Description

Technical Field

[0001] This invention relates to the fields of backup power supply control and AC power supply control, and particularly to a method and system for rapid switching and voltage regulation of mobile islanded power supplies. Background Technology

[0002] In the fields of backup power supply control and AC power supply control, existing solutions typically employ a decentralized monitoring and segmented control approach involving external power sources, inverters, energy storage batteries, and the load side. This approach suffers from limitations such as fragmented acquisition of external power availability and power quality information, disconnect between power supply mode determination and load priority determination, and a lack of unified sequence constraints for the isolation control of fast power outlets and inverter access. Existing methods often rely on separate processing paths for data acquisition, switching, and power maintenance, which can lead to inconsistent switching timing and difficulty in verifying post-switching states in islanded and emergency power supply scenarios. This makes it challenging to reliably achieve stable switching execution results for the isolation control of fast power outlets and inverter access. Existing technologies generally suffer from common shortcomings in the joint processing of status input sets, switching decision packages, switching execution results, regulated power supply status, load guarantee lists, power supply status packages, and traceable event logs. These shortcomings include the separation of data acquisition and decision-making links, the separation of decision-making and control links, and the separation of control and event recording processing links. This makes it difficult to form a consistent process for generating status input sets, switching decision packages, switching execution results, regulated power supply status, load guarantee lists, power supply status packages, and traceable event logs in scenarios where mobile islanded power supplies are rapidly switching and regulated. As a result, there is insufficient field correlation between switching execution and event recording processing, which affects the continuous invocation of anomaly markers in subsequent processing cycles. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a method for rapid switching and voltage regulation of mobile islanded power supplies, comprising:

[0004] S100 performs time alignment and validity verification based on the original monitoring data from the external power supply, inverter, energy storage battery and load side, and performs anomaly marking and unified coding to generate a status input set.

[0005] S200: Based on the state input set, perform power supply mode determination and load priority determination processing to generate a switching decision package;

[0006] S300, based on the switching decision package, performs fast power socket and inverter access isolation control processing, and generates switching execution results;

[0007] S400: Based on the switching execution result, perform energy storage battery charging and discharging control and inverter voltage regulation control to generate a regulated power supply state;

[0008] S500 performs load grading and load reduction control based on the stable power supply status, and generates a load guarantee list.

[0009] S600, based on the load guarantee list, performs monitoring quantity updates and fast power socket power supply control processing to generate power supply status packets;

[0010] S700 performs event recording processing based on power supply status packets to generate traceable event logs.

[0011] Further, the process of performing time alignment and validity checks, and executing anomaly marking and unified encoding to generate the state input set includes:

[0012] The time alignment process includes establishing a unified acquisition timeline by the status acquisition module, writing the status fields from the external power supply, inverter, energy storage battery, and load side within the same acquisition window to the same time identifier, and retaining the most recent valid field and writing an anomaly mark for monitoring data that arrives late or is temporarily missing from a certain source; the legality verification process includes field range verification, field type verification, acquisition order verification, and time sequence verification, and writing an anomaly mark for fields that fail the verification while retaining the original field content; the anomaly marking process includes writing the event type, triggering reason, and handling result fields from the previous round of traceable event logs into the associated segment of the anomaly marking field in this round; the unified encoding process includes performing field name unification and status value mapping for external power supply voltage status, frequency status, fluctuation anomaly flag, inverter operating status, fault protection status, energy storage battery charge status, charge / discharge permission status, load online status, and load change flag.

[0013] Furthermore, the process of determining the power supply mode includes:

[0014] The power supply mode determination process includes splitting the state input set into an external power supply determination subset, an inverter determination subset, an energy storage battery determination subset, and a load determination subset, and performing threshold rule group matching and state trigger rule group matching respectively. When the threshold matching result and the trigger matching result conflict, the conflict resolution is performed in the order of fault protection status, external power supply fluctuation abnormal flag, inverter operating status, and energy storage battery charge status, and the target power supply mode is output.

[0015] Furthermore, the load priority determination process includes:

[0016] The load priority determination process includes grouping and mapping the loads and determining the order of their activation based on preset load priority rules and the current power supply capacity status. This generates a load classification result that includes critical guaranteed loads, delayed activation loads, and interruptible loads. It also generates load activation strategies, load reduction strategies, and voltage stabilization constraints in conjunction with the target power supply mode. The switching decision package includes the target power supply mode, switching execution sequence identifier, load activation strategy, load reduction strategy, and voltage stabilization constraints. The switching execution sequence identifier is generated by the sequence mapping unit by calling a preset sequence table based on the target power supply mode, trigger matching result, and anomaly flag field.

[0017] Furthermore, the process of performing rapid power socket and inverter access isolation control processing and generating switching execution results includes:

[0018] The access isolation control process includes pre-access status confirmation, access path confirmation, isolation path confirmation, action issuance, status confirmation, anomaly marking, and result encapsulation. The pre-access status confirmation process involves reading a snapshot of the current monitoring data from the status acquisition module and comparing it with the target power supply mode, switching execution sequence identifier, and voltage regulation constraints in the switching decision package. When a field conflict occurs, an anomaly marker is written, and action issuance is paused according to the anomaly rollback field in the sequence template. The access path confirmation process includes confirming the on / off status, interlock status, and occupancy status of the power supply path to be closed. The isolation path confirmation process includes confirming the on / off status, reverse power supply risk status, and action permission status of the power supply path to be disconnected. The action issuance process includes calling the corresponding sequence template according to the switching execution sequence identifier and executing the fast power socket access action, path isolation action, inverter start action, hold action, or exit action in series according to the action waiting window in the sequence template. The current step status is maintained until the previous action receipt arrives and the waiting window ends. When the waiting window ends and the receipt field is missing, an anomaly marker is written, and the result confirmation processing link is triggered.

[0019] Furthermore, the process of controlling the charging and discharging of the energy storage battery and regulating the voltage of the inverter to generate a regulated power supply includes:

[0020] The energy storage battery charging and discharging control and inverter voltage regulation control processing includes parsing the power supply path status summary and protection trigger information in the switching execution result, loading the inverter voltage regulation control parameter call boundary, energy storage battery charging and discharging state switching boundary and load input cycle constraint fields in the voltage regulation constraints, reading the external power supply voltage status, frequency status, fluctuation anomaly flag, energy storage battery charge status and charging and discharging permission status, and load change flag returned by the status acquisition module, performing external power supply status determination, path status determination and protection current diversion processing, and adjusting the inverter voltage regulation control parameters according to the load change flag; the voltage regulation power supply status includes the inverter output status, energy storage battery status, current power supply capacity status, external power supply status determination result, power supply path status summary reference field, protection trigger information reference field, load change flag processing result and monitoring time identifier.

[0021] Furthermore, the process of implementing load grading and load reduction control to generate a load guarantee list includes:

[0022] The load grading and load reduction control process includes parsing the current power supply capacity status, generating a load operation group view, establishing a current action queue that includes action type, action sequence, cycle window, prohibition of load input, and load reduction trigger conditions, executing critical load input processing to generate critical load action records, executing delayed load input cycle control to generate delayed load input action records, and executing interruptible load reduction processing to generate interruptible load reduction action records when the current power supply capacity status does not meet the load input strategy; the load protection list includes the power supply status, protection level, and action time of each load.

[0023] Furthermore, the process of updating monitoring data and controlling power supply through the fast power outlet to generate a power status packet includes:

[0024] The monitoring update process includes generating a load assurance status summary, reading back the external power supply status, inverter status, and energy storage battery status, and combining the load assurance status summary and protection trigger information reference fields to synthesize an alarm status; the fast power socket power supply control process includes performing action arbitration based on the assurance level field and each load power supply status field in the load assurance list, and combining the current power supply capacity status reference relationship and the power supply path status summary reference relationship, issuing a fast power socket output emergency power supply command or maintaining the current output status and reading back the socket output status; the power supply status package includes the current power supply mode, external power supply status summary, inverter status, energy storage battery status, load assurance status summary, alarm status, and monitoring time identifier.

[0025] Furthermore, the process of recording and processing events to generate a traceable event log includes:

[0026] The event recording process includes extracting the current power supply mode field, load guarantee status summary field, alarm status field, and monitoring time identifier field from the power supply status packet; extracting the actual execution sequence identifier field and execution completion time field from the switch execution result; extracting the action time field and load power supply status field from the load guarantee list; performing time sequence alignment processing on the extracted results to generate event time sequence segments; and generating event type, triggering reason, execution action, handling result, key status summary, and operation source identifier based on the event time sequence segments. The traceable event log includes event type, triggering reason, execution action, handling result, key status summary, operation source identifier, switch time, and alarm reason.

[0027] Furthermore, a mobile islanded power supply fast switching and voltage regulation system includes: a status acquisition module, a power supply mode and load priority determination module, a switching execution control module, an energy storage battery charging and discharging and inverter voltage regulation control module, a load grading and load reduction control module, a monitoring quantity update and fast power socket power supply control module, and an event recording and processing module; the modules are connected in sequence to implement the method described in any of the above-mentioned embodiments.

[0028] The following are its main beneficial effects:

[0029] (1) In response to the existing solution's segmented determination and segmented distribution of external power supply, inverter, energy storage battery and load side, the status input set and the switching decision package incorporate power supply mode determination, load priority determination, switching execution sequence identifier, load input strategy, load reduction strategy and voltage regulation constraint into the same link, so that the fast power socket and inverter access isolation control, the energy storage battery charging and discharging control and inverter voltage regulation control, and the load graded input and load reduction control call objects are consistent.

[0030] (2) In response to the existing solution where the fast power socket access action, path isolation action and inverter action are executed separately, the fast power socket and inverter access isolation control organize the pre-access status confirmation, the path to be accessed confirmation and the path to be isolated confirmation according to the switching execution sequence identifier, and output the switching execution result, so that the subsequent energy storage battery charging and discharging control and inverter voltage regulation control call the power supply path status summary and protection trigger information, and the event record processing call the actual execution sequence identifier and execution completion time link remain continuous.

[0031] (3) In response to the existing solution where switching control, voltage regulation control, load control and recording processing are separated, the voltage regulation power supply status, the load guarantee list, the power supply status package and the traceable event log are generated in sequence and the object correspondence is maintained, so that the monitoring update and the fast power socket power supply control, event recording processing and subsequent status input set generation form a continuous calling relationship. The switching time, alarm cause and handling result in the traceable event log can be used in subsequent processing cycles. Attached Figure Description

[0033] Figure 2 This is a structural block diagram of a mobile islanded power supply fast switching voltage regulation system provided in an embodiment of this application. Detailed Implementation

[0034] Example 1: Refer to Figure 1 This is a flowchart illustrating a fast switching and voltage regulation method for mobile islanded power supplies provided in an embodiment of the present invention. The process may include at least steps S100-S700:

[0035] S100 performs time alignment and validity verification based on the original monitoring data from the external power supply, inverter, energy storage battery and load side, and performs anomaly marking and unified coding to generate a status input set.

[0036] S200: Based on the state input set, perform power supply mode determination and load priority determination processing to generate a switching decision package;

[0037] S300, based on the switching decision package, performs fast power socket and inverter access isolation control processing, and generates switching execution results;

[0038] S400: Based on the switching execution result, perform energy storage battery charging and discharging control and inverter voltage regulation control to generate a regulated power supply state;

[0039] S500 performs load grading and load reduction control based on the stable power supply status, and generates a load guarantee list.

[0040] S600, based on the load guarantee list, performs monitoring quantity updates and fast power socket power supply control processing to generate power supply status packets;

[0041] S700 performs event recording processing based on power supply status packets to generate traceable event logs.

[0042] S100 performs time alignment and validity verification based on the original monitoring data from the external power supply, inverter, energy storage battery and load side, and performs anomaly marking and unified coding to generate a status input set.

[0043] Specifically, S100 is executed by the status acquisition module within the instrument cabinet in a mobile islanded power supply scenario. This status acquisition module receives raw monitoring data from the external power supply access point, inverter, energy storage battery, and load side, and receives traceable event log fields from the previous round of operation as a reference for verification in the same round of acquisition. The external power availability indicates whether the external power supply access point is currently in an effective access state, a continuous power supply state, or a non-interrupted state; the power quality indicates the voltage status, frequency status, and fluctuation anomaly flags of the external power supply; the inverter status indicates the inverter's operating status and fault protection status; the energy storage battery state of charge is the percentage of remaining battery capacity, with the first occurrence of the state of charge abbreviated as State of Charge (SOC); and the load status indicates the load's online status and load change flags. The status acquisition module triggers the acquisition process when the system is powered on, an external power supply is connected, the inverter status changes, the load status changes, the alarm status changes, or the preset polling cycle arrives. When the trigger signal is manually verified, a supplementary acquisition process is executed. The supplementary acquisition process is integrated into the same data processing link and does not change the main step sequence of S100 to S700.

[0044] Furthermore, the status acquisition module reads voltage and frequency sampling values ​​from the external power supply input at the physical level, and reads the operating status word and fault protection status word from the inverter at the control level, the state of charge and charge / discharge permission status from the energy storage battery monitoring link, and the online status and load change flag of each load from the load-side monitoring link. The external power supply voltage status is generated by performing interval mapping on the voltage sampling values, the frequency status is generated by performing interval mapping on the frequency sampling values, and the fluctuation anomaly flag is generated by judging the change amplitude and number of consecutive changes in adjacent sampling periods; the inverter operating status is generated by reading the internal operating identifier of the inverter and converting it into a unified status field, the fault protection status is generated by reading the inverter protection trigger information and converting it into a unified status field; the energy storage battery state of charge is generated by reading the current state of charge value of the energy storage battery monitoring link and converting it into a state of charge field, the charge / discharge permission status is generated by reading the permission flag of the energy storage battery monitoring link and converting it into a permission field; the load online status is generated by reading the load-side switch status or branch on / off status, and the load change flag is generated by comparing the load current status or power status in adjacent sampling periods. Understandably, the term "generation" in this step refers to the field encapsulation action and does not involve subsequent power supply mode determination and load priority determination actions. The relevant determination actions are left to be executed in step S200.

[0045] Furthermore, after the data acquisition action is completed, S100 performs time alignment, validity verification, anomaly marking, and unified coding. Time alignment is achieved by the status acquisition module establishing a unified acquisition timeline, writing the status fields from the external power supply, inverter, energy storage battery, and load side within the same acquisition window to the same time identifier. When a monitoring value from a certain source arrives late or is temporarily missing, the status acquisition module retains the most recently valid field and writes an anomaly mark, thus maintaining the integrity of the status fields in the same round. Validity verification includes field range verification, field type verification, acquisition order verification, and time sequence verification. Fields that fail verification are not directly deleted but instead have an anomaly mark written and their original content retained for subsequent use by S200 in power supply mode determination and load priority determination. Unified coding refers to unifying field names and mapping status values ​​for external power supply voltage status, frequency status, fluctuation anomaly flag, inverter operating status, fault protection status, energy storage battery charge status, charge / discharge permission status, load online status, and load change flag, ensuring that output formats from different acquisition sources enter the same set of status fields. In this processing chain, the log recording unit synchronously provides the event type, triggering reason and handling result fields from the previous round of traceable event logs. The status acquisition module writes these three types of fields into the associated segment of the current round of abnormal marker field to characterize whether the current round of acquisition time is in the alarm subsequent running interval, the switching subsequent running interval or the load reduction subsequent running interval. The associated segment directly participates in the switching execution sequence identifier and load reduction strategy call in S200.

[0046] In the engineering embodiment, after the instrument cabinet, fast power socket, inverter, and energy storage battery are deployed at the temporary power supply point for island emergency repairs, the status acquisition module immediately triggers a data acquisition upon completion of the external power supply connection, reading the external power supply voltage status, frequency status, and fluctuation anomaly flag. Within the same acquisition window, it reads the inverter's operating status and fault protection status, the energy storage battery's charge status and charge / discharge permission status, and the load online status and load change flags of critical protection load branches and delayed-connection load branches. Subsequently, it performs time alignment, legality verification, anomaly marking, and unified coding, and writes the trigger reason field from the previous round of traceable event log into the associated segment of the anomaly mark field. If the on-site structure changes so that the load-side monitoring link converges into the instrument cabinet via a branch acquisition unit, the acquisition triggering conditions and processing order of S100 remain unchanged. The changed part is the access path of the original load status monitoring quantity, and the status acquisition module still performs encapsulation according to the unified field name. If the on-site structure is changed so that the inverter and energy storage battery monitoring links use the same communication acquisition interface, the S100 will still complete the acquisition first, and then complete the time alignment, legality verification, anomaly marking and unified coding. The unified coding action will split the shared interface output into inverter status field and energy storage battery status field and then write them into the same status input set.

[0047] Understandably, the minimum set of core parameters in S100 includes external power supply voltage status, frequency status, fluctuation anomaly flag, inverter operating status, fault protection status, energy storage battery state of charge, charge / discharge permission status, load online status, load change flag, time identifier, and anomaly flag fields. This minimum set directly corresponds to the power supply mode determination and load priority determination inputs of S200 and does not depend on redundant extended fields. Preferred extended functions include acquisition source identifier, acquisition channel identifier, and acquisition sequence identifier. After being written into the status field extension section, these preferred extended functions, along with the time identifier, status field, and anomaly flag, are encapsulated into the status input set. The output field names of the state input set in the main text implementation process include time identifier, state field and anomaly flag. The state field includes external power supply voltage status, frequency status, fluctuation anomaly flag, inverter operating status, fault protection status, energy storage battery charge status, charge / discharge permission status, load online status and load change flag. The state input set serves as the direct input for "power supply mode determination and load priority determination" in S200, and forms a closed loop connection with the traceable event log of the previous round in subsequent rounds of operation.

[0048] The technical effects of this step can be summarized as follows: Step S100 organizes the dispersed monitoring data from the external power supply, inverter, energy storage battery, and load side into a unified state input set, and incorporates the traceable event log fields from the previous round into the anomaly flag field, forming a continuous input link for subsequent judgment stages. Step S100 integrates time alignment, validity verification, anomaly flagging, and unified coding into the same processing flow, ensuring consistency between the source of the fields called for power supply mode determination and load priority determination. Step S100 establishes a parallel acquisition path for external power availability and power quality in mobile islanded power supply scenarios, which, together with inverter status, energy storage battery charge status, and load status, constitutes a tightened main chain input.

[0049] S200: Based on the state input set, perform power supply mode determination and load priority determination processing to generate a switching decision package;

[0050] Specifically, S200 is completed by the power supply mode determination and load priority determination execution link within the instrument cabinet. S200 receives the status input set output by S100 as a direct input source. The status input set contains a time identifier, status fields, and anomaly flags. The status fields include external power supply voltage status, frequency status, fluctuation anomaly flag, inverter operating status, fault protection status, energy storage battery state of charge, charge / discharge permission status, load online status, and load change flag. Further, upon startup, S200 reads preset load priority rules, threshold rule groups, and status trigger rule groups. The preset load priority rules are used for load classification. The threshold rule groups include external power supply voltage status thresholds, frequency status thresholds, energy storage battery state of charge thresholds, and inverter output capacity thresholds. The status trigger rule groups are used to respond to anomaly flag fields, alarm subsequent operating range flags, and switching subsequent operating range flags. The rule content is stored in the rule storage unit within the instrument cabinet and carries a rule version identifier. This rule version identifier is written into the encapsulation section of the switching decision package during this round of determination.

[0051] Furthermore, using the aforementioned state input set as input, the power supply mode determination processing link performs field parsing, rule matching, conflict resolution, and mode confirmation to obtain the target power supply mode, and records the trigger source in the determination process as a determination record field. The "power supply mode" in the power supply mode determination refers to the power supply path organization method in the current operating cycle, specifically including external power supply mode, inverter emergency power supply mode, parallel support mode, load reduction guarantee mode, switchback preparation mode, or fault protection mode; the "target power supply mode" refers to the mode field written into the switching decision package after this round of rule matching and called by the S300. The power supply mode determination and processing link first extracts the external power supply voltage status, frequency status, and fluctuation anomaly flag from the status input set to form an external power supply determination subset. Then, it extracts the inverter operating status, fault protection status, and inverter output capability-related fields to form an inverter determination subset. Next, it extracts the energy storage battery state of charge and charge / discharge permission status to form an energy storage battery determination subset. Finally, it extracts the load online status and load change flag to form a load determination subset. Subsequently, it performs threshold rule group matching to generate a threshold matching result, and then performs state trigger rule group matching to generate a trigger matching result. When the threshold matching result and the trigger matching result conflict, the power supply mode determination and processing link performs conflict resolution in the order of fault protection status, external power supply fluctuation anomaly flag, inverter operating status, and energy storage battery state of charge, outputting a single target power supply mode, and simultaneously writing the mode source field and conflict resolution flag field.

[0052] Furthermore, the online status and load change flags of the load are extracted from the status input set, and load priority determination is performed to generate load classification results and current power supply capacity status. The "load priority determination" refers to the process of grouping and mapping the loads and determining the order of their operation according to preset load priority rules and current power supply capacity. The "current power supply capacity status" refers to the power supply capacity field formed by the external power supply voltage status, frequency status, inverter output capacity threshold matching result, energy storage battery state of charge threshold matching result, and charge and discharge permit status. The load priority determination and processing link consists of a load classification unit, a strategy generation unit, and a constraint generation unit. The load classification unit reads the load identifier and guarantee level mapping relationship in the preset load priority rules and forms three groups: critical guarantee loads, delayed-entry loads, and interruptible loads based on the online status of the loads. The strategy generation unit generates load entry strategies and load reduction strategies based on the target power supply mode and the current power supply capacity status. The load entry strategy refers to the entry sequence, entry cycle, and prohibition conditions for various types of loads. The load reduction strategy refers to the load reduction sequence, load reduction trigger conditions, and load reduction maintenance conditions for interruptible loads. The constraint generation unit generates voltage regulation constraints based on the target power supply mode, the current power supply capacity status, and load change flags. The voltage regulation constraints refer to the boundary fields for subsequent energy storage battery charging and discharging control and inverter voltage regulation control calls, including inverter voltage regulation control parameter call boundaries, energy storage battery charging and discharging state switching boundaries, and load entry cycle constraint fields.

[0053] Understandably, the switching execution sequence identifier is generated by the sequence mapping unit within S200. The sequence mapping unit calls a preset sequence table based on the target power supply mode, trigger matching result, and anomaly flag field, and outputs the sequence identifier field corresponding to the access isolation control processing link of S300. The switching execution sequence identifier corresponds to the external power supply access sequence, inverter emergency activation sequence, parallel support sequence, load reduction switching sequence, or back-switch sequence. The "switching execution sequence identifier" refers to the sequential encoding field for the pre-access status confirmation, pending access path confirmation, pending isolation path confirmation, fast power socket access action, path isolation action and inverter start-up action, hold action, or exit action. This field does not perform access isolation action in this step; it only completes judgment and encapsulation. Furthermore, S200 reads the associated segment of the anomaly marker field in the state input set. If the associated segment records the event type, triggering reason, and handling result in the previous round of traceable event log, the state triggering rule group calls the corresponding switching execution sequence identifier and deload strategy according to the associated segment, thereby forming a cross-master step connection with the traceable event log output by S700, and maintaining field consistency with the anomaly marker field of the state input set generated by S100 in subsequent rounds.

[0054] In the engineering embodiment, when the temporary power supply point for emergency repair on the island enters the nighttime load fluctuation stage, the status input set output by S100 displays the external power frequency status fluctuation, the fluctuation abnormality flag is valid, the inverter operation status is normal, the energy storage battery charge status is within the permissible range, the critical protection load is online and the load change flag is rising. S200 first performs threshold rule group matching and status trigger rule group matching by the power supply mode determination processing link, and then confirms that the target power supply mode is the parallel support mode by the conflict resolution processing link. Subsequently, the sequence mapping unit generates the switching execution sequence identifier corresponding to the parallel support sequence. The load priority determination processing link in the same round classifies the communication protection equipment and the lighting main circuit into critical protection loads, classifies the auxiliary operation equipment into delayed input loads, classifies the non-critical operation equipment into interruptible loads, and generates load input strategies, load reduction strategies and voltage stabilization constraints according to the current power supply capacity status. If the site structure is changed to add a branch acquisition unit on the load side, the input of S200 is still the status input set, and the processing order of the power supply mode determination and load priority determination remains unchanged. The change is manifested in the different source paths of the load online status and load change flag fields. If the site structure is changed to the inverter output capacity threshold coming from the inverter internal configuration update, after the threshold rule group is updated, a new rule version identifier is written. S200 still generates the switching decision package according to the same encapsulation link and writes the rule version identifier into the encapsulation section for subsequent log recording processing.

[0055] Furthermore, in the encapsulation stage of S200, the decision package encapsulation unit writes the target power supply mode, the switching execution sequence identifier, the load input strategy, the load reduction strategy, and the voltage regulation constraint into the switching decision package, and simultaneously writes the time identifier, rule version identifier, judgment record field, and conflict resolution flag field. Understandably, the minimum set of core parameters of the switching decision package is the target power supply mode, the switching execution sequence identifier, the load input strategy, the load reduction strategy, and the voltage regulation constraint. This minimum set directly serves as the input field set for the "fast power socket and inverter access isolation control" in S300. The time identifier, rule version identifier, judgment record field, and conflict resolution flag field are preferred extended fields, and participate in field traceability association when S300 generates the switching execution result and S700 generates the traceable event log. The output product of S200 is the switching decision package. The switching decision package is received by S300 in the cross-master step relationship, and the voltage stabilization constraint is invoked in S400. The load input strategy and the load reduction strategy are invoked in S500 to form a continuous input relationship in the same round of operation link.

[0056] The technical effects of this step can be summarized as follows: Step S200 organizes the state input set into a switching decision package that integrates the target power supply mode, switching execution sequence identifier, load input strategy, load reduction strategy, and voltage stabilization constraint. The input relationships between the main chain fields and subsequent access isolation control, voltage stabilization control, and load control are fixed within this step. Step S200 incorporates threshold rule groups and state trigger rule groups in parallel into the decision chain, and introduces anomaly marker fields associated with certain segments to participate in sequence and strategy calls. Cross-round connection relationships are written into the same encapsulated chain. In mobile islanded power supply scenarios, Step S200 maintains synchronous execution of power supply mode determination and load priority determination, ensuring consistency in the source of fields called in subsequent main steps.

[0057] S300, based on the switching decision package, performs fast power socket and inverter access isolation control processing, and generates switching execution results;

[0058] Specifically, S300 is executed by the switching execution control module within the instrument cabinet. This module establishes control connections with the fast power socket, inverter, and path isolation execution unit, and maintains a monitoring quantity readback connection with the status acquisition module. The input source for S300 is the switching decision package output by S200. In this step, the switching decision package is parsed into the target power supply mode, switching execution sequence identifier, load input strategy, load reduction strategy, voltage stabilization constraint, time identifier, rule version identifier, decision record field, and conflict resolution flag field. The target power supply mode and the switching execution sequence identifier constitute the main execution fields for this step, the voltage stabilization constraint constitutes the boundary verification field for this step, and the load input strategy and load reduction strategy constitute the path conflict check field for this step. The "fast power socket" refers to the controlled interface node corresponding to the external power input terminal and the emergency output terminal. The "inverter access isolation control" refers to the sequential control processing link that performs access, hold, exit and path disconnection actions on the power supply path where the inverter is located. The "access isolation control" in this step includes four continuous processing stages: action issuance, status confirmation, abnormal marking and result encapsulation. It does not include energy storage battery charging and discharging control and inverter voltage regulation control. The relevant content is executed when the switching execution result is called by S400.

[0059] Furthermore, the triggering conditions of S300 are jointly managed by the switching execution control module according to the automatic triggering link and the manual confirmation triggering link. The automatic triggering link starts when the switching decision packet arrives and passes the verification, while the manual confirmation triggering link starts when a conflict resolution flag field or an alarm subsequent operation interval flag appears after the switching decision packet arrives. The manual confirmation triggering link only changes the timing of the action command, without changing the execution order of the pre-access status confirmation, pending access path confirmation, pending isolation path confirmation, fast power socket access action, path isolation action, inverter start action, hold action, or exit action. The switching execution control module first performs packet integrity verification and version consistency verification on the switching decision packet, then reads the switching execution sequence identifier and calls the corresponding sequence template. The sequence template is stored in the sequence table storage unit in the instrument cabinet. The sequence table storage unit saves the action sequence definition, action waiting window, status confirmation field, and abnormal rollback field for the external power access sequence, inverter emergency input sequence, parallel support sequence, load reduction switching sequence, and back-off sequence. Understandably, the “sequence template” refers to a combination record of the arrangement relationship of action steps and the status confirmation rule, and does not replace the field judgment in the switching decision package, nor does it change the meaning of the S200 output field.

[0060] Furthermore, the aforementioned switching decision package is used as input, and the status is verified through the pre-access status confirmation processing link to obtain the pre-access status confirmation result, which is then recorded as a pre-execution confirmation field. The "pre-access status confirmation" refers to the process of simultaneously verifying the status of the external power supply access terminal, the operable status of the fast power socket, the inverter operating status, the fault protection status, the current location status of the path isolation execution unit, and the online status of the load before the action is issued. In specific implementation, the switching execution control module reads the current monitoring snapshot from the status acquisition module and compares it with the target power supply mode, switching execution sequence identifier, and voltage regulation constraint execution fields in the switching decision package. When a field conflict occurs between the monitoring snapshot and the switching decision package, the switching execution control module writes the conflicting content into an anomaly flag and suspends the action issuance according to the anomaly rollback field in the sequence template, waiting for manual confirmation of the trigger link or a new round of S100 and S200 outputs. The "path to be accessed confirmation" refers to confirming the on / off status, interlock status, and occupancy status of the power supply path to be closed. The "path to be isolated confirmation" refers to confirming the on / off status, reverse power supply risk status, and action permission status of the power supply path to be disconnected. Both are executed by the path status confirmation unit. The path status confirmation unit outputs the path to be accessed confirmation result and the path to be isolated confirmation result, and writes both into the path confirmation field. The path confirmation field is entered into the action command sub-link as a command precondition.

[0061] Further, the action sequence is extracted from the switching execution sequence identifier, and the fast power socket access action, path isolation action, and inverter start-up action, hold action, or exit action are executed to generate a process status record. This process status record is used for result confirmation processing link calls. The "fast power socket access action" refers to the process where the switching execution control module sends an access command to the corresponding actuator of the fast power socket and receives a position receipt or status receipt. The "path isolation action" refers to the process where the switching execution control module sends a disconnection command or a hold-disconnection command to the path isolation execution unit and receives a position receipt or status receipt. The "inverter start-up action, hold action, or exit action" refers to the process where the switching execution control module issues a start command, hold command, or exit command to the inverter operating status field based on the target power supply mode and reads the inverter receipt field. The action command sub-link is executed sequentially according to the action waiting window in the sequence template. The current step state is maintained until the previous action receipt arrives and the waiting window ends. An exception flag is written and the result confirmation processing link is triggered when the waiting window ends and the receipt field is missing. The next action is started when the previous action receipt arrives and the status value meets the sequence template definition. In Technical Solution 1, the parallel support sequence follows the order of "path isolation action first, fast power socket access action second, inverter hold action last." In Technical Solution 2, the inverter emergency activation sequence follows the order of "path to be isolated confirmation, path isolation action, inverter start action, fast power socket access action." In Technical Solution 3, the switchback sequence follows the order of "pre-access status confirmation, path to be accessed confirmation, fast power socket access action, inverter exit action, path isolation action verification." Technical Solutions 1, 2, and 3 are selected by the switching execution sequence identifier, without adding a main step field. When the product structure changes, only the sequence template content of the sequence table storage unit is adjusted.

[0062] Furthermore, after the action is executed, S300 enters the result confirmation processing link to confirm the result of the execution process and mark any anomalies, generating the switching execution result containing the execution status, actual execution sequence identifier, protection trigger information, execution completion time, and power supply path status summary. "Result confirmation" refers to checking the action command record, location receipt, status receipt, inverter receipt, and path status readback item by item according to the sequence template, and outputting an action completion judgment; "anomaly marking" refers to recording receipt timeouts, status inconsistencies, protection triggers, path occupancy conflicts, and action interruptions in a field-based manner. The "Execution Status" refers to the completion status field of this round of access isolation control, including status values ​​of completion, interruption, or partial completion; the "Actual Execution Sequence Identifier" refers to the sequence field actually executed in this round. When the switching execution sequence identifier experiences an abnormal rollback during execution, the actual execution sequence identifier records the name of the rolled-back sequence; the "Protection Trigger Information" refers to the summary field formed by the inverter protection trigger receipt, the path isolation execution unit protection status receipt, or the fast power socket protection status receipt; the "Execution Completion Time" refers to the time field when the result is confirmed and the switching execution result is encapsulated; the "Power Supply Path Status Summary" refers to the summary field of the on / off status of each power supply path, the inverter access status, and the fast power socket access status at the end of this round of execution. The result confirmation processing link consists of a receipt verification unit, a status readback unit, and a result encapsulation unit. The receipt verification unit is responsible for pairing the action command record with the receipt record, the status readback unit is responsible for reading the path status snapshot after execution, and the result encapsulation unit is responsible for writing the execution status, actual execution sequence identifier, protection trigger information, execution completion time, and power supply path status summary into the switching execution result.

[0063] In the engineering embodiment, after a typhoon, the external power fluctuation anomaly flag at the temporary power supply point for emergency repairs on the island remains valid. After S200 outputs the switching decision package, S300 reads the inverter emergency activation sequence corresponding to the switching execution sequence identifier. First, it performs a pre-access status confirmation and reads the operable status of the fast power socket, the inverter's operating status, and the current position status of the path isolation execution unit. Then, it performs confirmation of the path to be accessed and the path to be isolated. When the path confirmation field meets the preconditions for action command, the switching execution control module issues the path isolation action and the inverter start action according to the sequence template, and issues the fast power socket access action after the inverter receipt arrives. If protection trigger information appears in the inverter receipt during execution, S300 writes the protection trigger information into the anomaly flag and calls the anomaly rollback field, stops subsequent actions, and enters the result confirmation processing link, finally generating the switching execution result containing the execution status, actual execution sequence identifier, protection trigger information, execution completion time, and power supply path status summary. If the on-site structure is changed to an integrated setup of a fast power socket actuator and a path isolation actuator, the input of the S300 is still the switching decision package. The pre-access status confirmation, the path to be accessed confirmation, and the path to be isolated confirmation are still executed in the same order. The change is that the action command objects are merged, and the result confirmation processing link still outputs the switching execution result with the same field name.

[0064] Understandably, the minimum set of core parameters of the S300 includes the target power supply mode, switching execution sequence identifier, voltage regulation constraint, pre-access status confirmation result, path to be accessed confirmation result, path to be isolated confirmation result, execution status, actual execution sequence identifier, protection trigger information, execution completion time, and power supply path status summary. The target power supply mode, switching execution sequence identifier, and voltage regulation constraint are derived from the switching decision package. The execution status, actual execution sequence identifier, protection trigger information, execution completion time, and power supply path status summary constitute the main field set of the switching execution result. Preferred extended fields include a pre-execution confirmation field, a path confirmation field, an action command record summary, an exception marker, and a rule version identifier. These preferred extended fields are written into the extended section of the switching execution result and participate in subsequent log recording processing. The output product of S300 is the switching execution result. The power supply path status summary and protection trigger information in the switching execution result are used as direct input fields for the S400 "energy storage battery charging and discharging control and inverter voltage regulation control". The actual execution sequence identifier and execution completion time are used as direct extraction fields for the S700 "event recording processing". The abnormal marker is written into the traceable event log by the log recording unit and then participates in the processing link of S100 and S200 in subsequent rounds.

[0065] In summary, the technical effects of this step are as follows: Step S300 converts the sequence fields in the switching decision package into an executable action link for the fast power socket and inverter access isolation control, and writes the action receipt, path status readback, and exception flag into the same switching execution result. Step S300 incorporates pre-access status confirmation, path to be accessed confirmation, and path to be isolated confirmation into the action command preconditions, ensuring that the fields called by S400 and the fields extracted by S700 are formed synchronously within this step. Step S300 maintains the same field output structure in scenarios where automatic triggering links and manual confirmation triggering links coexist, facilitating continuous round-robin operation.

[0066] S400: Based on the switching execution result, perform energy storage battery charging and discharging control and inverter voltage regulation control to generate a regulated power supply state;

[0067] Specifically, S400 is executed by the energy storage battery charging and discharging control and inverter voltage regulation control execution link within the instrument cabinet. This execution link maintains data interaction relationships with the inverter, energy storage battery monitoring link, status acquisition module, and log recording unit. The main input source of S400 is the switching execution result output by S300. In this step, the switching execution result is parsed into execution status, actual execution sequence identifier, protection trigger information, execution completion time, and power supply path status summary. Simultaneously, S400 calls the voltage regulation constraint in the switching decision package generated by S200. This voltage regulation constraint serves as a boundary field in this step and participates in the energy storage battery charging and discharging control and inverter voltage regulation control. The "energy storage battery charging and discharging control" refers to the control process of switching and maintaining the charging, discharging, or maintenance states of the energy storage battery. The "inverter voltage regulation control" refers to the process of regulating the target AC output power of the inverter. The "regulated power supply state" refers to the operating state object encapsulated and output in this step, including the inverter output state, energy storage battery state, and current power supply capacity state after this round of voltage regulation control. Further, the S400 is triggered by a combination of switching execution completion trigger, external power supply state change trigger, load change flag trigger, and protection trigger information trigger. The switching execution completion trigger comes from the execution completion time field, the external power supply state change trigger and load change flag trigger come from the monitoring data read back from the state acquisition module, and the protection trigger information trigger comes from the protection trigger information field in the switching execution result.

[0068] Specifically, the aforementioned switching execution result is used as input. The power supply path status parsing and protection trigger information parsing processing link is used to split the fields, obtaining the power supply path status summary parsing result and the protection trigger information parsing result. The parsing results are recorded as the pre-stabilization status field. In this step, the "power supply path status summary" is used to determine whether the external power supply path is in the connected state, whether the inverter path is in the connected state, and whether the parallel support path is in the valid state. The "protection trigger information" is used to determine whether the inverter has entered a restricted operating range, exited an operating range, or is waiting for a reset range. After parsing the switching execution result, the execution link retrieves the voltage stabilization constraint from the switching decision package and performs constraint loading processing. The constraint loading processing writes the inverter voltage stabilization control parameter call boundary, the energy storage battery charge / discharge state switching boundary, and the load input cycle constraint fields into the current control context. Understandably, the voltage stabilization constraint does not change the actual execution sequence identifier in this step; it only participates in subsequent control parameter selection, state switching determination, and abnormal current diversion processing. Subsequently, the execution link reads the external power supply voltage status, frequency status, fluctuation anomaly flag, inverter operating status, fault protection status, energy storage battery charge status and charge / discharge permission status, and load change flags returned by the status acquisition module. The charge status appears for the first time as the English abbreviation State of Charge (SOC). The returned monitoring quantity is then matched with the pre-stabilization status field to generate a set of voltage regulation control input fields.

[0069] Further, the external power supply voltage status, frequency status, and fluctuation anomaly flag are extracted from the voltage regulation control input field set, and an external power supply status determination is performed. The path access status is extracted from the power supply path status summary parsing result, and a path status determination is performed. Then, the protection status is extracted from the protection trigger information parsing result, and protection shunt processing is performed. This generates an external power supply anomaly status determination result or an external power supply recovery and power quality threshold satisfaction status determination result. The "external power supply anomaly status" refers to a state where any field of the external power supply voltage status, frequency status, or fluctuation anomaly flag triggers an anomaly, and the state, combined with the power supply path status summary and protection trigger information, enters the inverter support operation processing link. The "external power supply recovery and power quality threshold satisfaction status" refers to a state where the external power supply voltage status and frequency status match the threshold rules, the fluctuation anomaly flag does not trigger an anomaly, and the state, combined with the power supply path status summary, enters the external power supply recovery operation processing link. Based on the external power supply abnormality determination result, the energy storage battery charging and discharging control sub-link reads the energy storage battery's state of charge and charging / discharging permission status. If the charging / discharging permission status allows and the protection trigger information does not indicate exit from operation, a discharge status control command is issued, and the discharge status is written into the energy storage battery status field. The inverter voltage regulation control sub-link reads the inverter voltage regulation control parameter call boundary in the voltage regulation constraint, loads the inverter output adjustment parameters in combination with the operating range corresponding to the target power supply mode, issues the inverter output target AC power control command, and reads back the inverter output status and writes it into the inverter output status field. In response to the external power supply recovery and power quality meeting the threshold conditions, the energy storage battery charging and discharging control sub-link issues a charging status control command when the energy storage battery's state of charge and charging / discharging permit states meet the switching boundary, and issues a maintenance status control command when the switching boundary is not met, and writes the charging status or maintenance status into the energy storage battery status field; the inverter voltage regulation control sub-link keeps the inverter output adjustment parameters operating within the voltage regulation constraint range, and reads back the inverter operating status and output status and writes them into the inverter output status field.

[0070] Further, S400 adjusts the inverter voltage regulation control parameters according to the load change flag. The "load change flag" refers to the change field output by the status acquisition module after comparing adjacent sampling windows of the load status. In this step, it is used to determine whether the load suddenly increases, decreases, or remains stable. In specific implementation, the execution link is set up with a load change response processing link. When the load change flag indicates a sudden increase in load, the inverter voltage regulation control sub-link calls the corresponding adjustment parameter group according to the load input cycle constraint field in the voltage regulation constraint, and simultaneously checks the state of charge and charge / discharge permission status of the energy storage battery to maintain the combination relationship between the energy storage battery status and the inverter output status. When the load change flag indicates a sudden decrease in load, the inverter voltage regulation control sub-link operates according to another set of adjustment parameters, and the energy storage battery charge / discharge control sub-link verifies the charging status, discharging status, or maintenance status. When the load change flag indicates a stable load, the execution link maintains the current adjustment parameters and performs periodic readback. If the protection trigger information is updated during this process, the execution link first writes the protection trigger information update field, and then triggers the protection diversion process. The protection diversion process only modifies the parameter call and state switching path, without changing the structure of the S400 output field. Thus, the S400 forms a continuous operation link at the action level: "parse the switching execution result—call the voltage regulation constraint—determine the external power supply status—execute the energy storage battery charging and discharging control and the inverter voltage regulation control—correct the control parameters according to the load change flag—encapsulate the output".

[0071] In the engineering embodiment, after the temporary power supply point for island emergency repair completes S300, the switching execution result shows that the inverter path is in the access state, the external power supply path is in the abnormal operation range, and the protection trigger information has not been triggered to exit operation. S400 receives the switching execution result and calls the voltage regulation constraint in the switching decision package. First, the power supply path status parsing and protection trigger information parsing processing link loads the current round control context. Then, it reads the external power supply voltage status, frequency status, fluctuation abnormal flag, energy storage battery charge status and charge / discharge permission status, and load change flag returned by the status acquisition module. After the external power supply abnormal status determination result is established, the energy storage battery charge / discharge control sub-link issues a discharge status control command, and the inverter voltage regulation control sub-link issues a target AC power control command and reads back the inverter output status. When the main lighting circuit and communication support equipment are simultaneously connected, causing a sudden load increase as indicated by the load change flag, the S400 calls the load surge adjustment parameter group according to the voltage stabilization constraint and performs a readback verification. Subsequently, it encapsulates the inverter output status, energy storage battery status, current power supply capacity status, and the load change flag processing result into the stabilized power supply status. If the field structure is changed to use the same communication interface for the inverter and energy storage battery monitoring links, the input to the S400 remains the switching execution result, and the called fields remain the voltage stabilization constraint. The change is manifested in the merging of the readback monitoring input paths, while the structure of the stabilized power supply status field remains unchanged.

[0072] Further, in the encapsulation stage of S400, the regulated power supply state is generated by the regulated state encapsulation unit. This unit writes the inverter output state, energy storage battery state, current power supply capacity state, external power supply state determination result, power supply path state summary reference field, protection trigger information reference field, load change flag processing result, and monitoring time identifier into the regulated power supply state. The "current power supply capacity state" is jointly generated in this step from the external power supply state determination result, inverter output state, energy storage battery state, and protection trigger information, serving as a direct input field for load grading and load reduction control in S500. The power supply path state summary reference field and protection trigger information reference field are used for subsequent log recording processing field traceability. The monitoring time identifier is used for the time correlation between this round of regulated control and subsequent monitoring quantity updates. Understandably, the minimum set of core parameters of S400 includes a power supply path status summary, protection trigger information, voltage regulation constraints, external power supply voltage status, frequency status, fluctuation anomaly flag, energy storage battery state of charge, charge / discharge permission status, load change flag, inverter output status, energy storage battery status, and current power supply capacity status. The first nine items are the main control input fields, and the last three items are the set of main fields for the regulated power supply status. Preferred extended fields include external power supply status determination result, power supply path status summary reference field, protection trigger information reference field, load change flag processing result, and monitoring time identifier. The preferred extended fields are invoked when associated with the execution fields of S500, S600, and S700.

[0073] The technical effects of this step can be summarized as follows: S400 merges the power supply path status summary and protection trigger information from the switching execution result with the voltage regulation constraints in the switching decision package and loads them into the same control context. Based on the same round-robin monitoring data, it completes the charging and discharging control of the energy storage battery and the voltage regulation control of the inverter. S400 maintains the same output field structure in two operating ranges: when the external power supply is abnormal and when the external power supply is restored and the power quality meets the threshold, thus stabilizing the S500 call path. S400 incorporates the load change flag into the inverter voltage regulation control parameter adjustment link, ensuring a continuous connection between the voltage regulation power supply status and subsequent load grading and load reduction control.

[0074] S500 performs load grading and load reduction control based on the stable power supply status, and generates a load guarantee list.

[0075] Specifically, S500 is completed by the load grading and load shedding control execution link within the instrument cabinet. This load grading and load shedding control execution link maintains data and control connections with the status acquisition module, the fast power socket control link, the load-side switch execution unit, and the log recording unit. S500 receives the regulated power supply status output by S400 as its main input and calls the load input and load shedding strategies from the switching decision package generated by S200 as strategy inputs. The "stabilized power supply status" in this step includes at least the inverter output status, energy storage battery status, current power supply capacity status, external power supply status determination result, power supply path status summary reference field, protection trigger information reference field, load change flag processing result, and monitoring time identifier. The "load tiered activation and load reduction control" refers to the continuous control processing of sequential activation, tidal activation, and load reduction actions for critical guaranteed loads, delayed activation loads, and interruptible loads. The "load guarantee list" refers to the status object encapsulated and output after this round of load control, recording the power supply status, guarantee level, and action time of each load, and is directly invoked by the S600's monitoring update and fast power socket power supply control. The triggering conditions of the S500 include the arrival of the stabilized power supply status trigger, the change in current power supply capacity status trigger, the change in load change flag processing result trigger, and the change in the protection trigger information reference field trigger. These triggering conditions are uniformly determined by the load management triggering unit and written into the control context of this round.

[0076] Furthermore, taking the aforementioned stable power supply status as input, the current power supply capacity status analysis and load status mapping processing link performs field parsing to obtain the current power supply capacity status analysis result and load operation group view, and records the analysis result as the pre-load control status field. The "current power supply capacity status" in this step refers to the determination field of the executable range of load input and load reduction actions, including the input range, restricted input range, or load reduction operation range; the "load operation group view" is jointly generated by the load identifier, protection level mapping relationship in the preset load priority rules, and the load online status and load change flags collected by S100. Specifically, the load grading input and load reduction control execution link first reads the load input strategy and load reduction strategy in the switching decision package, then reads the current power supply capacity status, protection trigger information reference field, and load change flag processing result in the stable power supply status, and groups the critical protection loads, delayed input loads, and interruptible loads for loading; subsequently, a current action queue is established, which records the action type, action sequence, cycle window, prohibited input conditions, and load reduction trigger conditions for each load or load group. Understandably, the "load input strategy" is used to generate the input action queue in this step, and the "load reduction strategy" is used to generate the load reduction action queue in this step. Both participate in action arbitration in the same round of control and do not change the structure of the voltage stabilization power supply status field.

[0077] Furthermore, the load input strategy is extracted from the switching decision package and the critical backup load input process is executed, generating a critical backup load action record. The phrase "inputting critical backup loads in a preset order" refers to the process of issuing input commands one by one according to the critical backup load sequence field defined in the load input strategy and reading back the status feedback from the load-side switch execution unit. Before the critical backup load input process begins, the load grading input and load reduction control execution link first verifies the current power supply capacity status analysis result. If the current power supply capacity status analysis result is in the available input range, the critical backup load input action is executed; if the current power supply capacity status analysis result is in the restricted input range, only the critical backup load input action corresponding to the allowed input mark in the load input strategy is executed; if the protection trigger information reference field shows that the inverter is in the restricted operating range, the critical backup load input action is executed according to the restricted sequence field and the cycle window is extended synchronously. After each action is completed, the status readback unit reads the load-side switch execution unit's receipt and the load online status readback field, and writes the action completion status, load power supply status, and action time into the critical load action record; when the receipt times out or the status is inconsistent, the abnormal flag sub-link writes the action abnormal flag and triggers the action arbitration unit to review the load reduction strategy.

[0078] Further, the load input strategy is extracted from the switching decision package and delayed load input cycle control is executed to generate a delayed load input action record. Here, "inputting delayed loads according to cycle" refers to the process of progressively issuing input instructions according to the cycle window field, sequence field, and prohibited input condition field in the load input strategy, and performing readback verification between adjacent actions. At the beginning of each cycle window, the load management cycle control unit reads the current power supply capacity status analysis result and the load change flag processing result. When the current power supply capacity status analysis result is still within the available input range and the load change flag processing result does not indicate a sudden load increase, the next delayed load input action is executed. When the current power supply capacity status analysis result enters the restricted input range or the load change flag processing result indicates a sudden load increase, the next delayed load input action is paused, and the pause status is written to the action record field, waiting for the arrival of a new round of voltage stabilization power supply status before continuing arbitration. This processing path maintains the action queue order unchanged, only updating the action timing field, facilitating the subsequent extraction of the action time and load power supply status field by the S700 from the load guarantee list for event recording processing.

[0079] Furthermore, when the current power supply capacity status does not meet the load input strategy, the S500 performs interruptible load reduction processing and generates an interruptible load reduction action record. "Current power supply capacity status does not meet the load input strategy" means that the current power supply capacity status analysis result enters the load reduction operation range, or the protection trigger information reference field displays a restricted operation status, or the load change flag processing result continuously indicates a sudden load increase and the cycle control is paused. "Interruptible load reduction" means performing a disconnection action or maintaining a disconnection action on the interruptible load according to the load reduction sequence field, load reduction trigger condition field, and load reduction hold condition field in the load reduction strategy. Specifically, the action arbitration unit first locks the critical protection load action queue and freezes subsequent actions for delayed load input, then calls the load reduction action queue to issue load reduction instructions to each interruptible load; after each load reduction action is completed, the status readback unit reads the load online status readback field and verifies the current power supply capacity status analysis result. If the current power supply capacity status analysis result returns to the restricted input range or the input range, then the addition of new load reduction actions is stopped and the stop time is written into the interruptible load reduction action record. In technical solution one, the interruptible load descent processing operates along a single load-by-load descent path, suitable for scenarios with a small number of loads. In technical solution two, the interruptible load descent processing operates along a load group-by-load segmented descent path, suitable for scenarios with multiple branches in parallel. In technical solution three, the interruptible load descent processing operates along a path driven by the priority of the protection trigger information reference field, suitable for scenarios where the inverter's operating state changes frequently. Technical solutions one, two, and three are invoked by the path selection field in the descent strategy and do not change the structure of the S500 output fields.

[0080] In the engineering embodiment, after the temporary power supply point for island emergency repair completes S400, the voltage stabilization power supply status shows that the current power supply capacity is in the limited input range, the protection trigger information reference field has not triggered the exit operation, and the load change flag processing result indicates that the load is stable. After S500 reads the load input strategy and load reduction strategy in the switching decision package, it first puts the communication support equipment branch and the lighting main circuit branch in the key protection load in a preset order, reads back the status feedback of the load-side switch execution unit and writes it into the action record; then it starts the delayed input load cycle control, and puts the auxiliary operation equipment branch in the first cycle window. If the access of the newly added temporary operation equipment on site causes the load change flag processing result to change to a load surge, and the current power supply capacity status changes to the load reduction operation range, S500 suspends the subsequent delayed input load action and executes the interruptible load reduction processing, and issues a load reduction command to the non-critical operation equipment branch; after the status feedback unit verifies that the current power supply capacity status has returned to the limited input range, it stops the new load reduction action and records the stopping time. If the on-site structure is changed to integrate the load-side switch execution unit and the status readback unit, the input of the S500 will still be the regulated power supply status and the load input strategy and load reduction strategy in the switching decision package. The action arbitration process and field output order will remain unchanged. The change is that the receipt path and the readback path will be merged.

[0081] Further, during the encapsulation phase, the S500 load guarantee list encapsulation unit summarizes the action records of critical guaranteed loads, delayed-start loads, and interruptible load reduction actions to generate the load guarantee list. The main fields written into the load guarantee list in this step include the power supply status of each load, the guarantee level, and the action time. Extended fields include action type, action sequence status, cycle window status, action anomaly flag, current power supply capacity status reference field, protection trigger information reference field, and monitoring time identifier. The "power supply status of each load" refers to the field indicating whether each load is currently in an activated, inactive, suspended, or reduced-load state. The "guarantee level" corresponds to the classification field for critical guaranteed loads, delayed-start loads, or interruptible loads. The "action time" refers to the time when the current action is completed, suspended, or reduced-load stops. Understandably, the core parameter set of the load assurance list consists of the power supply status, assurance level, and action time of each load. This minimum set is directly used for monitoring updates and fast power socket power supply control by the S600. The extended fields participate in the event log processing field traceability of the S700, and indirectly participate in the processing links of the S100 and S200 in subsequent rounds through the traceable event log. The output product of the S500 is the load assurance list. In the cross-master step relationship, the load assurance list is received by the S600 for monitoring updates and fast power socket power supply control, and the action time and load power supply status are extracted by the S700 for event log processing.

[0082] The technical effects of this step can be summarized as follows: S500 loads the regulated power supply status and the load input and load reduction strategies from the switching decision package into the same action arbitration link, forming continuous control processing for critical guaranteed loads, delayed input loads, and interruptible loads. S500 writes load input in a preset order, load input by tick, and interruptible load reduction into the same load guarantee list, ensuring that the fields called by S600 and S700 are consistent. S500 maintains the same output field structure under scenarios of changes in current power supply capacity status and changes in load change flag processing results, facilitating continuous round-robin operation and subsequent recording processing.

[0083] S600, based on the load guarantee list, performs monitoring quantity updates and fast power socket power supply control processing to generate power supply status packets;

[0084] Specifically, the S600 is completed by the monitoring quantity update and fast power socket power supply control execution link in the instrument cabinet. The execution link receives the load guarantee list output by the S500 as the main input and maintains data interaction with the status acquisition module, fast power socket control link, inverter monitoring link, energy storage battery monitoring link and log recording unit. The "Load Guarantee List" in this step is used to indicate the power supply status, guarantee level, and action time of each load, and serves as the source of action constraints for the fast power socket to output emergency power supply. The "Monitoring Quantity Update" refers to the process of performing round-robin readings, field verification, and time correlation on the external power supply status, inverter status, energy storage battery status, load guarantee status, and alarm status. The "Fast Power Socket Power Supply Control" refers to the process of controlling the fast power socket to output emergency power supply or maintain the current output status according to the load guarantee list. The "Power Supply Status Package" refers to the status object encapsulated and output in this step, containing the current power supply mode, external power supply status summary, inverter status, energy storage battery status, load guarantee status summary, alarm status, and monitoring time identifier, and is directly invoked by the event recording processing of S700. The S600 triggering conditions include load guarantee list arrival trigger, action time update trigger, alarm status change trigger, and monitoring polling cycle trigger. The triggering conditions are uniformly determined by the monitoring and scheduling unit and written into the current execution context.

[0085] Furthermore, using the aforementioned load assurance list as input, the load assurance status summary generation and processing link performs field merging and status mapping to obtain the load assurance status summary, which is then recorded as a field before monitoring updates. The "load assurance status summary" refers to a summary field formed by summarizing the power supply status, assurance level, and action time of each load. The summary content includes the status of critical assurance loads in operation, the status of delayed loads in operation, the status of interruptible loads being deloaded, and the most recent action time. The load assurance status summary generation and processing link retains the reference relationship of the anomaly marker field during merging. When an anomaly marker exists in the load assurance list, the summary field is synchronously written with the anomaly summary marker for subsequent alarm status update processing links to call. Understandably, the load assurance status summary does not replace the load assurance list; the load assurance list still serves as the direct source for the S700 to extract action times and load power supply status.

[0086] Furthermore, the system reads back and updates monitoring data from the status acquisition module, inverter monitoring link, and energy storage battery monitoring link to generate external power supply status, inverter status, energy storage battery status, and alarm status. Specifically, the monitoring data update execution link first reads the external power supply voltage status, frequency status, and fluctuation anomaly flag to form an external power supply status update subset. Then, it reads the inverter operating status, fault protection status, and inverter output status to form an inverter status update subset. Next, it reads the energy storage battery charge status, charge / discharge permission status, and energy storage battery status to form an energy storage battery status update subset. Finally, it updates the alarm status by combining the load guarantee status summary and protection trigger information reference fields. In this step, "External Power Supply Status" refers to a combined record of the current external power supply operating status field and the abnormality field. "Inverter Status" refers to a combined record of the inverter's operating status, fault protection status, and output status. "Energy Storage Battery Status" refers to a combined record of the energy storage battery's state of charge, charge / discharge permission status, and current charging, discharging, or maintenance status. "Alarm Status" refers to a summary field indicating whether there are any external power supply abnormalities, inverter fault protection triggering, energy storage battery operating restrictions, or load action abnormalities in this round of operation. The alarm status update processing link performs field synthesis in the order of external power supply status, inverter status, energy storage battery status, and load guarantee status summary, and writes a conflict flag when fields conflict. The conflict flag does not trigger action rollback in this step; it only participates in the event recording processing of S700.

[0087] Further, S600 controls the fast power socket to output emergency power supply according to the load guarantee list. The fast power socket power supply control execution link reads the guarantee level field and the power supply status field of each load in the load guarantee list, and performs action arbitration by combining the current power supply capacity status reference relationship in the regulated power supply status formed by S400 and the power supply path status summary reference relationship formed by S300. In technical solution one, when the critical guarantee load is in operation and the current power supply capacity status allows emergency output, a fast power socket output emergency power supply command is issued and the socket output status is read back; in technical solution two, when the interruptible load reduction status continues and the alarm status includes the external power abnormality field, the fast power socket maintains the current output status and periodically reads back the socket output status; in technical solution three, when the alarm status includes the inverter fault protection trigger field, the fast power socket power supply control execution link stops adding new output actions and writes a power supply control abnormality flag. The above technical solutions one, two, and three are jointly selected by the action arbitration unit according to the load guarantee list, the alarm status, and the monitoring polling cycle, and the output field structure remains consistent. In this step, "output emergency power supply" refers to the process of issuing output commands and receiving status acknowledgments from the actuator corresponding to the fast power socket. The status acknowledgments are written into the output status field of the fast power socket and then participate in the update association of the external power status summary or alarm status.

[0088] In the engineering embodiment, after the temporary power supply point for island emergency repairs generates the load guarantee list in S500, the monitoring and scheduling unit receives the load guarantee list arrival trigger. First, it generates a summary of the critical guarantee load activation status, delayed activation load activation status, interruptible load descent status, and most recent action time from the load guarantee status summary processing link. Then, it updates the execution link with the monitored quantities, reading back the external power supply voltage status, frequency status, and fluctuation anomaly flag; reading back the inverter operating status, fault protection status, and inverter output status; and reading back the energy storage battery charge status, charge / discharge permission status, and energy storage battery status. Finally, it synthesizes the alarm status. If the critical guarantee load activation status is established and the current power supply capacity is still within the output range, the fast power socket power supply control execution link issues a fast power socket output emergency power supply command and reads back the socket output status. If the external power fluctuation anomaly flag is triggered again during operation and the interruptible load descent status persists, the execution link switches to the path of maintaining the current output status and writes a power supply control anomaly flag. If the on-site structure is changed to integrate the fast power socket actuator and the status readback interface, the S600 will still receive the load guarantee list as the main input, and the order of monitoring quantity update and fast power socket power supply control processing will remain unchanged. The change is manifested in the merging of the readback path of the fast power socket output status field.

[0089] Further, in the encapsulation stage of S600, the power supply status package is generated by the power supply status package encapsulation unit. The power supply status package encapsulation unit references the current power supply mode field from S200 or the switching decision package, writes the external power supply status summary, inverter status, energy storage battery status, and alarm status from the monitoring quantity update execution link of this step, writes the load guarantee status summary from the load guarantee status summary generation processing link, and writes the monitoring time identifier. The "external power supply status summary" refers to the summary field after compressing and mapping the operating and abnormal fields in the external power supply status, and the "monitoring time identifier" refers to the time field when the current round of monitoring quantity update is completed and the power supply status package is encapsulated. Understandably, the minimum set of core parameters for the power supply status package is the current power supply mode, external power supply status summary, inverter status, energy storage battery status, load guarantee status summary, alarm status, and monitoring time identifier. This minimum set directly serves as the input field set for the "event recording processing" of S700. Preferred extended fields include conflict flags, power supply control abnormal flags, fast power socket output status fields, and rule version identifier reference fields. These preferred extended fields participate in subsequent field tracing and log recording. The output product of S600 is the power supply status packet. S700 extracts the current power supply mode, load guarantee status summary and alarm status from the power supply status packet to perform event recording processing, and in subsequent rounds, it forms a cross-master step connection with S100 and S200 through the traceable event log.

[0090] The technical effects of this step can be summarized as follows: S600 loads the load guarantee list and the monitoring data from the same round-robin reading into the same monitoring data update and fast power socket power supply control execution link, forming a unified encapsulation of power supply operation status and emergency output status. S600 writes the current power supply mode, external power supply status summary, inverter status, energy storage battery status, load guarantee status summary, alarm status, and monitoring time identifier into the power supply status package, ensuring consistency in the source of the fields called by S700. S600 maintains the same output field structure in scenarios where both monitoring polling cycle triggering and status change triggering coexist, facilitating continuous round-robin operation and subsequent recording processing.

[0091] S700 performs event recording processing based on power supply status packets to generate traceable event logs;

[0092] Specifically, S700 is completed by the event recording and processing execution link within the instrument cabinet. This link includes a field extraction unit, a timing association unit, an event judgment unit, a log writing unit, and a log indexing unit, and maintains data connectivity with the log recording unit and the status acquisition module. S700 receives the power supply status packet output by S600 as its main input, and simultaneously calls the switching execution result and load guarantee list as associated inputs. The power supply status packet provides the current power supply mode, load guarantee status summary, alarm status, and monitoring time identifier; the switching execution result provides the actual execution sequence identifier and execution completion time; and the load guarantee list provides the action time and load power supply status. "Event recording processing" refers to the continuous processing of extracting, associating, judging, encapsulating, and writing the status fields, action fields, and alarm fields in this round of power supply operation. The "traceable event log" refers to a log object stored according to a field structure. The fields include event type, triggering reason, executed action, handling result, key status summary, and operation source identifier, and store the switching time, alarm reason, and handling result at the field level for subsequent rounds of S100 and S200 to call. The S700 triggering conditions include power supply status packet arrival trigger, alarm status change trigger, execution completion time arrival trigger, and monitoring time identifier polling trigger. The triggering conditions are uniformly determined by the event scheduling unit and written into the current round of log processing context.

[0093] Further, taking the aforementioned power supply status package as input, the field extraction unit performs main field extraction to obtain the current power supply mode field, load guarantee status summary field, alarm status field, and monitoring time identifier field, and records these four types of fields as the power supply status extraction result. Subsequently, the field extraction unit extracts the actual execution sequence identifier field and execution completion time field from the switching execution result, and extracts the action time field and load power supply status field from the load guarantee list, and writes the extraction results into the action status extraction result. The "key status summary" in this step consists of the current power supply mode field, load guarantee status summary field, alarm status field, power supply path status summary reference field, or protection trigger information reference field. If the power supply status package does not directly write the reference field, the event record processing execution link generates the key status summary by associating the monitoring time identifier field with the extended field of the most recent round of switching execution result through the log indexing unit. Understandably, the field extraction unit does not rewrite the upstream field name. The field extraction unit only performs field reading, field verification, and field caching. The field name remains consistent with the previous main step, so that in subsequent rounds, S100 writes the event type, triggering reason, and handling result fields from the previous round's traceable event log into the exception flag field of the status input set.

[0094] Furthermore, the timing association unit performs timing alignment processing on the power supply status extraction results and action status extraction results to generate event timing segments. The "timing alignment processing" refers to establishing a time window based on the monitoring time identifier field, the execution completion time field, and the action time field, and associating alarm status changes, load action changes, and switching execution sequence changes within the same time window. In specific implementation, the timing association unit first uses the execution completion time field as a candidate time for switching events, then expands the association window forward and backward according to the action time field, writing the load power supply status changes into this window; subsequently, the alarm status field corresponding to the monitoring time identifier field is merged into the same window to form an event timing segment. If the action time field is missing or multiple action time fields overlap, the timing association unit writes the missing or overlapping status into the timing anomaly marker field and retains the original field content for the event judgment unit to call. The "switching time" in this step is determined by the relationship between the execution completion time field and the time window in the event time sequence segment. When the execution completion time field is valid, the switching time is taken from the execution completion time field; when the execution completion time field is missing but the time sequence anomaly flag field is valid, the switching time is taken from the monitoring time identifier field and the time sequence anomaly flag field is written into the log.

[0095] Furthermore, the event determination unit generates event type, triggering cause, executed action, handling result, key status summary, and operation source identifier based on the event time sequence fragment. The "event type" refers to the classification field for switching, alarm, load reduction, recovery, or status update, with the determination criteria derived from the actual execution sequence identifier field, alarm status field, load power supply status field, and load protection status summary field. The "triggering cause" refers to the combination of fields that triggers this round of event determination, originating from the alarm status field, time sequence anomaly marker field, load power supply status change field, or protection trigger information reference field. The "executed action" refers to the action summary corresponding to this round of events, originating from the actual execution sequence identifier field, the action time field in the load protection list, and the load power supply status field. The "handling result" refers to the status merging field after the execution of this round of actions, originating from changes in the alarm status field, changes in the load protection status summary field, and changes in the current power supply mode field. The "operation source identifier" refers to the source field corresponding to the automatically triggered link or the manually confirmed triggered link, originating from the event scheduling unit context field and the extended field written in the preceding main step. In the event determination unit, in the event of a field conflict, conflict resolution is performed in the following order: alarm status field first, actual execution sequence identifier field second, load power supply status field third, and monitoring time identifier field last. The conflict resolution marker is then written to the log extension field. In Technical Solution 1, the event determination unit outputs log records according to a single-event, single-window path, suitable for scenarios with low switching action density. In Technical Solution 2, the event determination unit outputs log records according to a merged window path for similar events, suitable for scenarios with frequent alarm status changes. In Technical Solution 3, the event determination unit outputs log records according to the dominant window path of the switching event, suitable for scenarios with frequent changes in the switching execution sequence. All three technical solutions are selected by the log template version identifier field, which is written in the same round by the log writing unit without changing the main field structure.

[0096] In the engineering embodiment, after the temporary power supply point for island emergency repair completes the S600, the power supply status packet reaches the event scheduling unit. The field extraction unit first extracts the current power supply mode field, load guarantee status summary field, alarm status field, and monitoring time identifier field. Then, it extracts the actual execution sequence identifier field and execution completion time field from the switching execution result, and extracts the action time field and load power supply status field from the load guarantee list. Subsequently, the timing association unit establishes a time window according to the execution completion time field, and merges the action time field and alarm status field corresponding to the load reduction action into the same event timing segment. The event determination unit determines the event type as load reduction based on the event timing segment, the triggering reason as external power supply abnormality and alarm status change, the execution action as the action summary corresponding to the load reduction switching sequence, and the handling result as critical guarantee loads remain in operation and interruptible loads are reduced. The critical status summary consists of the current power supply mode field, load guarantee status summary field, and alarm status field, and the operation source identifier is taken from the automatic triggering link. If the site structure is changed to an integrated setup of the log recording unit and the log indexing unit, the S700 will still receive the power supply status packet as the main input, and will still call the switching execution result and the load guarantee list as associated inputs. The timing association and event judgment order will remain unchanged. The change is manifested in the merging of the log writing path and the index writing path.

[0097] Further, the log writing unit writes the event type, triggering reason, executed action, handling result, key status summary, and operation source identifier into the log recording unit by field, and simultaneously writes the switching time, alarm reason, and handling result fields to generate the traceable event log. The "alarm reason" in this step is generated and written separately from the field corresponding to the source of the alarm status change in the triggering reason field. The "switching time" is output by the timing association unit, and the "handling result" is output by the event judgment unit. After generating the traceable event log, the log indexing unit establishes index fields, including the monitoring time identifier, event type, and operation source identifier, and writes them into the log index section for easy field retrieval in subsequent rounds. Specifically, the output product of S700 is the traceable event log. The event type, triggering reason, and handling result fields in the traceable event log are called by S100 in subsequent rounds and written into the anomaly flag field of the status input set. S200 calls the corresponding switching execution sequence identifier and load reduction strategy based on the anomaly flag field, thereby forming a closed-loop relationship across the main steps. Understandably, the minimum set of core parameters of the traceable event log includes event type, triggering reason, execution action, handling result, key status summary, operation source identifier, switching time and alarm reason. Preferred extended fields include time sequence anomaly marker field, conflict resolution marker field, log template version identifier field and index field. The preferred extended fields participate in subsequent field tracing and template switching, without changing the field names called by S100 and S200.

[0098] The technical effects of this step can be summarized as follows: S700 completes field extraction, timing association, and event determination of the power supply status packet, switching execution result, and load guarantee list within the same event recording processing execution chain, and generates the traceable event log according to a fixed field structure. S700 writes the switching time, alarm cause, and handling result, along with the event type, triggering reason, execution action, key status summary, and operation source identifier, into the same log object, ensuring that the field sources called by S100 and S200 remain consistent in subsequent rounds. S700 maintains the same output field structure in scenarios where power supply status change triggering and polling triggering coexist, facilitating continuous round-by-round operation and log traceability.

[0099] Example 2: Figure 2 A structural block diagram of a mobile islanded power supply fast switching voltage regulation system according to an embodiment of the present invention is shown. Figure 2 As shown, the structure may include:

[0100] The status acquisition module 01 receives raw monitoring data from the external power supply, inverter, energy storage battery, and load side. It also receives traceable event log fields from the previous operation, performs time alignment, validity verification, anomaly marking, and unified encoding processing to generate a status input set. Specifically, this module triggers the acquisition process when the system powers on, an external power supply is connected, the inverter status changes, the load status changes, the alarm status changes, or a preset polling cycle arrives. A supplementary acquisition process is executed when the trigger signal input is manually reviewed, and this process is integrated into the same data processing link. At the physical level, it reads voltage and frequency sampling values ​​from the external power supply; at the control level, it reads the operating status word and fault protection status word from the inverter; it reads the state of charge and charge / discharge permission status from the energy storage battery monitoring link; and it reads the online status and load change flags of each load from the load-side monitoring link.

[0101] The power supply mode and load priority determination module 02 is connected to the status acquisition module. It is used to receive the status input set, read the preset load priority rules, threshold rule groups, and status trigger rule groups, perform power supply mode determination and load priority determination processing, and generate a switching decision package. Specifically, this module receives the status input set as direct input. At startup, it reads the preset load priority rules, threshold rule groups, and status trigger rule groups stored in the rule storage unit in the instrument cabinet. The threshold rule group includes the external power supply voltage status threshold, frequency status threshold, energy storage battery charge status threshold, and inverter output capability threshold. The status trigger rule group is used to respond to the abnormal flag field, the alarm subsequent operating range flag, and the switching subsequent operating range flag.

[0102] The switching execution control module 03, connected to the power supply mode and load priority determination module, is used to receive the switching decision packet, perform fast power socket and inverter access isolation control processing, and generate switching execution results. Specifically, this module receives the switching decision packet and parses it into target power supply mode, switching execution sequence identifier, load input strategy, load reduction strategy, voltage stabilization constraint, time identifier, rule version identifier, determination record field, and conflict resolution flag field. Among them, the target power supply mode and switching execution sequence identifier constitute the main execution field of this step, the voltage stabilization constraint constitutes the boundary verification field of this step, and the load input strategy and load reduction strategy constitute the path conflict check field of this step. The triggering conditions are jointly managed by the switching execution control module according to the automatic triggering link and the manual confirmation triggering link. The automatic triggering link is started when the switching decision package arrives and passes the verification. The manual confirmation triggering link is started when the conflict resolution flag field or the alarm subsequent operation interval flag appears after the switching decision package arrives. The manual confirmation triggering link only changes the timing of the action command, and does not change the execution order of the pre-access status confirmation, pending access path confirmation, pending isolation path confirmation, fast power socket access action, path isolation action, inverter start action, hold action, or exit action.

[0103] The energy storage battery charging / discharging and inverter voltage regulation control module 04, connected to the switching execution control module, is used to receive the switching execution result and call the voltage regulation constraints in the switching decision package to perform energy storage battery charging / discharging control and inverter voltage regulation control processing, generating a regulated power supply state. Specifically, this module receives the switching execution result and parses it into execution state, actual execution sequence identifier, protection trigger information, execution completion time, and power supply path state summary, while simultaneously calling the voltage regulation constraints in the switching decision package. The triggering timing is jointly composed of switching execution completion trigger, external power supply state change trigger, load change flag trigger, and protection trigger information trigger. The switching execution completion trigger comes from the execution completion time field, the external power supply state change trigger and load change flag trigger come from the monitoring data read back by the state acquisition module, and the protection trigger information trigger comes from the protection trigger information field in the switching execution result. The power supply path status parsing and protection trigger information parsing processing link splits fields to obtain the power supply path status summary parsing result and the protection trigger information parsing result. The parsing results are recorded as the pre-stabilization status field. The power supply path status summary parsing result is used to determine whether the external power supply path is in the connected state, whether the inverter path is in the connected state, and whether the parallel support path is in the effective state. The protection trigger information parsing result is used to determine whether the inverter has entered the restricted operating range, exited the operating range, or is waiting for a reset range. After parsing the switching execution result, the execution link retrieves the voltage stabilization constraints from the switching decision package and performs constraint loading processing, writing the inverter voltage stabilization control parameter call boundary, the energy storage battery charge / discharge state switching boundary, and the load input cycle constraint fields into the current round of control context.

[0104] The load grading and load reduction control module 05, connected to the energy storage battery charging / discharging and inverter voltage regulation control module, receives the regulated power supply status and invokes the load input and load reduction strategies in the switching decision package to perform load grading and load reduction control processing and generate a load guarantee list. Specifically, this module receives the regulated power supply status as the main input, which includes the inverter output status, energy storage battery status, current power supply capacity status, external power supply status determination result, power supply path status summary reference field, protection trigger information reference field, load change flag processing result, and monitoring time identifier. Simultaneously, it invokes the load input and load reduction strategies in the switching decision package as strategy inputs. Triggering conditions include regulated power supply status arrival trigger, current power supply capacity status change trigger, load change flag processing result change trigger, and protection trigger information reference field change trigger. These triggering conditions are uniformly determined by the load management trigger unit and written into the current control context. The current power supply capacity status is parsed through the current power supply capacity status parsing and load status mapping processing link to obtain the current power supply capacity status parsing result and load operation group view. The parsing result is recorded as the load control pre-state field. The current power supply capacity status parsing result includes the available range, the restricted range, or the reduced load operation range. The load operation group view is jointly generated by the load identifier in the preset load priority rules, the guarantee level mapping relationship, and the load online status and load change flags collected by the status acquisition module.

[0105] The monitoring quantity update and fast power socket power supply control module 06, connected to the load grading and load reduction control module, receives the load guarantee list, performs monitoring quantity update and fast power socket power supply control processing, and generates a power supply status package. Specifically, this module receives the load guarantee list as the main input. The load guarantee list indicates the power supply status, guarantee level, and action time of each load, and serves as the source of action constraints for the fast power socket to output emergency power supply. Triggering conditions include load guarantee list arrival trigger, action time update trigger, alarm status change trigger, and monitoring polling cycle trigger. The triggering conditions are uniformly determined by the monitoring and scheduling unit and written into the current execution context. The load assurance status summary generation and processing link merges fields and maps them to obtain the load assurance status summary. The load assurance status summary is then recorded as a field before monitoring updates. The load assurance status summary refers to the summary field formed by summarizing the power supply status, assurance level, and action time of each load. The summary content includes the status of critical assurance loads, the status of delayed loads, the status of interruptible loads being deloaded, and the most recent action time. The load assurance status summary generation and processing link retains the reference relationship of the abnormal marker field during merging. When an abnormal action marker exists in the load assurance list, the summary field is synchronously written with the abnormal summary marker for subsequent alarm status update processing links to call.

[0106] The event logging and processing module 07, connected to the monitoring quantity update and fast power socket power supply control module, receives the power supply status packet and calls the switching execution result and load guarantee list to perform event logging processing and generate a traceable event log. Specifically, this module receives the power supply status packet as the main input and calls the switching execution result and load guarantee list as associated inputs. The power supply status packet provides the current power supply mode, load guarantee status summary, alarm status, and monitoring time identifier. The switching execution result provides the actual execution sequence identifier and execution completion time. The load guarantee list provides the action time and load power supply status. Triggering conditions include power supply status packet arrival trigger, alarm status change trigger, execution completion time arrival trigger, and monitoring time identifier polling trigger. The triggering conditions are uniformly determined by the event scheduling unit and written into the current round of log processing context. The main field extraction is performed by the field extraction unit to obtain the current power supply mode field, load guarantee status summary field, alarm status field, and monitoring time identifier field, and these four types of fields are recorded as the power supply status extraction results. Subsequently, the actual execution sequence identifier field and execution completion time field are extracted from the switching execution results, and the action time field and load power supply status field are extracted from the load guarantee list. The extraction results are written into the action status extraction results. In this step, the key status summary consists of the current power supply mode field, load guarantee status summary field, alarm status field, power supply path status summary reference field, or protection trigger information reference field. If the power supply status packet is not directly written into the reference field, the event record processing execution link generates the key status summary by associating the monitoring time identifier field with the extended field of the most recent round of switching execution results through the log index unit. The field extraction unit does not rewrite the upstream field names, but only performs field reading, field verification, and field caching. The field names remain consistent with the previous main steps.The timing association unit performs timing alignment processing on the power supply status extraction results and action status extraction results to generate event timing segments. Timing alignment processing refers to establishing a time window based on the monitoring time identifier field, the execution completion time field, and the action time field, and associating alarm status changes, load action changes, and switching execution sequence changes within the same time window. In specific implementation, the execution completion time field is used as the candidate time for switching events, and the association window is expanded forward and backward according to the action time field. The load power supply status changes are written into this window, and then the alarm status field corresponding to the monitoring time identifier field is merged into the same window to form an event timing segment. If the action time field is missing or multiple action time fields overlap, the timing association unit writes the missing or overlapping status into the timing anomaly marker field and retains the original field content for the event judgment unit to call. In this step, the switching time is jointly determined by the execution completion time field and the time window relationship in the event timing segment. When the execution completion time field is valid, the switching time is taken from the execution completion time field. When the execution completion time field is missing but the timing anomaly marker field is valid, the switching time is taken from the monitoring time identifier field and written into the timing anomaly marker field in the log.
