Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution network communication power supply and operation and maintenance monitoring, and particularly relates to a remote discharge control system and method for a battery for power distribution network communication. BACKGROUND

[0002] In the technical field of power distribution network communication power supply and operation and maintenance monitoring, lead-acid batteries are generally configured as backup energy at power distribution network communication sites, and the relationship between the rated capacity and discharge testing affects the power supply reliability and maintenance plan of communication equipment. At present, the common practice is to rely on manual access to the load on site, and to carry out discharge in a constant resistance or constant current manner. The data records are scattered and the time scale is not unified, and the remote visibility and controllability are insufficient. During the discharge process in a wide voltage range, the bus voltage decreases over time, and the traditional constant power control link lacks pre-compensation for the voltage decay trend. The controller output often fluctuates in power target and declines in power at the end, resulting in low stability and repeatability of the rated capacity results.

[0003] The existing sampling link mostly uses single-ended voltage sampling and shunt resistance sampling. Influenced by common-mode disturbance, cable voltage drop and temperature drift, voltage and current measurement errors are easily accumulated at both low and high frequencies, and the power closed-loop reference is unstable. At the control algorithm level, the proportional-integral-derivative control with fixed parameters does not distinguish the differences between the state of charge stages, and the trade-off between dynamic response and steady-state deviation is insufficient at the early, middle and late discharge stages. Moreover, there is a lack of time reference management consistent with the power target caliber, causing problems such as beat drift and inconsistent power caliber between different modules.

[0004] In terms of thermal management, when the outdoor cabinet environment temperature rises, the air cooling efficiency decreases, and the temperature difference regulation between the power device and the cooling medium lacks segmented thresholds and hysteresis strategies. The heat dissipation mode is prone to jitter, and the thermal load and power control interfere with each other, triggering protection shutdown or passive derating, and the discharge process is prone to interruption. In terms of safety protection, the overcurrent, overtemperature and undervoltage judgment links are scattered, the action threshold and write-back control are not linked, the remote emergency stop response link is delayed, the event records are not systematic, and it is difficult to support the generation of full-process tracing and recovery strategies.

[0005] In the communication and data links, the remote parameter issuance, sampling data upload and execution receipt lack redundancy check, breakpoint resume and state confirmation mechanism, leading to loss of instructions, missing samples and time scale misplacement at individual sites under weak link conditions; the report generation and strategy write-back process is not closed-loop, and there is a lack of structured association between the rated capacity curve, parameter change list and next round of task configuration, making it difficult to achieve execution continuity and data consistency in long-term unattended sites.

[0052] Embodiment one: refer to Figure 1 In the field of power distribution network communication power supply and operation and maintenance monitoring, Figure 1 The flowchart of the battery remote discharge control method for distribution network communication provided by the embodiment of the application can at least include steps S1-S6:

[0053] Step S1: obtain remote setting parameters and communication robustness strategy, standardize, check and parameter boundary check based on electronic load capacity list and battery rated protection threshold, generate task configuration set and control initial value, and issue storage to obtain initialization completion mark based on instruction reply requirement and breakpoint continuation rule;

[0055] Step S3: Selecting a segmented parameter control table item based on the interval index and the hysteresis rule, calculating the duty cycle and processing the power deviation based on the power error signal and the integral limit, and generating a compact flag;

[0056] Step S4: Adjusting the coolant flow and refrigeration power based on the three-section threshold and the hysteresis logic to obtain the thermal state according to the compact flag, generating the power write-back instruction and issuing the confirmation to obtain the write-back confirmation flag based on the power allowed bandwidth and the duty cycle constraint boundary;

[0057] Step S5: Generating the emergency stop flag based on the overcurrent, overtemperature and undervoltage determination based on the thermal state and the state sequence, and generating the recovery process guide based on the time index coupling relationship and the event record;

[0058] Step S6: Verifying and filling in the data based on the sampling beat and the breakpoint continuation rule from the recovery process guide and the state sequence, generating the structured report data based on the capacity measurement criterion, adjusting the task configuration set based on the curve segment set and the change segment set, and obtaining the adjustment parameter set.

[0059] S1: Obtain remote setting parameters and communication robustness strategy, based on the electronic load capacity list and the battery rated protection threshold to perform normalization, check and parameter boundary check, generate task configuration set and control initial value, and based on instruction reply requirement and breakpoint continuation rule to issue storage to obtain initialization completion flag;

[0060] After identity verification and permission confirmation are completed at the centralized management end, remote setting parameters and communication robustness strategies are obtained, the remote setting parameters including target power, cutoff voltage, time length, heat dissipation threshold table, sampling period, record granularity, concurrent quantity and site identification, the communication robustness strategies including instruction receipt requirement, retry number and interval, link health determination threshold, breakpoint resume rule and time synchronization rule. Specifically, the obtained remote setting parameters and communication robustness strategies are standardized according to a unified standard, including unit conversion, dimension correction, time reference alignment and field completion; for entries involving numerical ranges, legality checks are performed, target power and site capability list are compared with electronic load capability list, cutoff voltage is compared with the lower limit and safety belt of the rated range and protection threshold of the battery under test, time length and sampling period are checked for divisibility and upper limit constraint; for the heat dissipation threshold table involving table structure, interval continuity and threshold order are checked, abnormal entries are marked according to preset rules and manual review is prompted. Further, entries that have been standardized and checked are summarized and deployed as a task configuration set, the task configuration set recording parameter source, version number, timestamp and applicable site range, and solidifying the association between fields in a key-value mapping structure, and clearly indicating the dependent links of target power and cutoff voltage, time length and sampling period, heat dissipation threshold table and temperature sampling; the task configuration set is cached at the remote terminal as a unified input for subsequent links, and provides a searchable query entry for subsequent extraction and consistency mapping. Understandably, the task configuration set is exposed as a read-only handle after formation, for subsequent extraction process calls, and the link health determination threshold and breakpoint resume rule are registered in the communication robustness strategy to ensure that there is a recovery basis when link jitter occurs in the delivery process; thus, the output of this step is the task configuration set, which is used for extraction and mapping in the next step, and is used as the basis for pre-data before the initialization completion flag is generated in subsequent collection and control.

[0061] After the task configuration set is called, three types of key entries, target power, cutoff voltage and duration, are sequentially extracted by field name; boundary check is performed on the extracted data, the upper limit comparison is performed between target power and power bearing list of electronic load, the lower limit and safety belt comparison is performed between cutoff voltage and rated range and protection threshold of the battery under test, and the intersection operation is performed between duration and available window of the site to give executable section, if out of range is found, the correction is made according to the preset rounding strategy and priority rules and is registered in the correction rule table. Specifically, to ensure that each entry has a directly executable caliber in the subsequent control link, the consistency mapping is performed on target power, cutoff voltage and duration: target power is mapped to power target caliber required for control synthesis, cutoff voltage is mapped to local protection threshold caliber, and duration is mapped to task scheduling caliber; at the same time, according to the registration relationship of heat dissipation threshold table and sampling period in the task configuration set, the collection tempo and heat threshold switching tempo matched with the three types of key entries are derived, so that the control caliber and the heat management caliber keep the same time reference. Further, the three types of entries after boundary check and consistency mapping are encapsulated to form control initial value, which contains the numerical set of power target caliber, protection threshold caliber and task scheduling caliber, and records the reference identifier and mapping relationship summary of the correction rule table; the control initial value and the communication robustness strategy formed in the previous step jointly constitute the delivery object, providing complete input for the next step of storage and activation. Understandably, the control initial value as the precondition of collection and control will be acquired for setting of sampling tempo and generation of state sequence in the subsequent collection step, so the control initial value is written into the to-be-delivered cache at the end of this step and the check information and time stamp are generated, so as to perform consistency check in the next step; thus, the output of this step is the control initial value, which explicitly references the task configuration set, ensuring consistency with the parameter link formed in the previous step.

[0062] After the control initial value and the communication robustness strategy are obtained, an instruction channel to a local controller of a target station is established, and a segmented configuration of a downlink message is performed according to an instruction acknowledgement requirement and a retry number and interval specified by the communication robustness strategy, the control initial value is placed in a parameter downlink segment, the communication robustness strategy is placed in a link strategy segment, and time synchronization information and a version number and a time stamp of a task configuration set are attached to a first segment. Specifically, a link probe instruction is first sent, and after it is determined that a link health state meets a threshold according to an acknowledgement, parameter transmission is started; then, the control initial value is written into a parameter area of the local controller according to a field order, a local check is requested after the writing is completed, and a parameter check result is returned by the local controller after the check is completed; if an exception is returned, a retransmission process or a breakpoint resume process is triggered according to the communication robustness strategy, and only unconfirmed fields are retransmitted; when the control initial value is confirmed to be correct, the communication robustness strategy is started to be downlinked, and a write is performed on the acknowledgement requirement, the retry number and interval, the breakpoint resume rule, and the time synchronization rule, and a local confirmation is requested. Further, after the two data segments are both confirmed, a storage and activation process is triggered: a persistent instruction is downlinked to the local controller, so that the content of the parameter area is stored; then, an activation instruction is downlinked, requiring the local controller to refresh an initial register area of an internal control loop according to a power target threshold and a protection threshold, configure a local task timer according to a task scheduling threshold, load the link strategy segment to make the communication side enter a robustness mode, and return an activation acknowledgement after the refresh and the timer configuration are completed. To ensure that a subsequent acquisition and control link operates according to a unified benchmark, a time synchronization operation is initiated after the activation acknowledgement, and a time benchmark is aligned to the time stamp of the task configuration set; after the alignment is completed, an initialization completion flag is generated and returned to the remote terminal, the remote terminal records a correspondence between the initialization completion flag and a local confirmation record, and the current session is closed. Understandably, the initialization completion flag serves as a trigger signal of an acquisition step and an essential input of state sequence acquisition, and will be read first in a subsequent acquisition to set a sampling start time and a beat; the power target threshold and the protection threshold in the control initial value will be used for constant power joint control and triple protection, respectively; and the task scheduling threshold will be used for aligning a record granularity and a planned update period during report archiving and task rewriting. Thus, the input of the present step is the control initial value and the communication robustness strategy, the output is the initialization completion flag and the local confirmation record, and through the field reference relationship of the acquisition, control, heat dissipation, protection, and archiving, a unified parameter link and an execution link with the task configuration set as the root are formed, so that the subsequent steps can be directly called and continuously operated.

[0063] S2: Obtain a state sequence from the initialization completion flag and the control initial value based on a local acquisition timer synchronization pulse, calculate a state of charge, and generate an interval index based on a segmented parameter control table preset interval, generate a feedforward compensation amount based on a compensation mapping entry through voltage attenuation evaluation;

[0064] After receiving the initialization completion flag generated in the previous step, the control initial value corresponding to it is called, which includes the power target aperture, the protection threshold aperture, and the task scheduling aperture, and the timestamp and verification information are recorded. Specifically, first, according to the task scheduling aperture, the acquisition period and the starting time are set, so that the local acquisition timer is consistent with the timestamp; then the voltage measurement channel and the current measurement channel are self-checked, including channel open circuit detection, zero point offset estimation and range adaptation, so that the acquisition hardware is in a usable state. During the acquisition process, the voltage measurement channel uses differential access, combined with the front-stage isolation and anti-aliasing filter to complete the acquisition of the instantaneous voltage; the current measurement channel uses a magneto-electric sensor to acquire the group terminal current, and the bias and temperature drift term are corrected once before acquisition. To ensure the time consistency of voltage and current, a synchronization pulse is sent by the local acquisition timer at the beginning of each sampling period to trigger the voltage measurement channel and the current measurement channel to complete synchronous sampling, and the two original samples are paired and cached according to the same time index. The cached original samples are denoised, which sequentially completes outlier rejection, smoothing and baseline regression. The outlier rejection uses amplitude threshold and change rate threshold joint determination, the smoothing uses fixed window sliding smoothing, and the baseline regression corrects the baseline according to the steady state segment of the previous task period. After denoising, the voltage sample sequence and the current sample sequence organized in time sequence are generated, and the two are spliced into a state sequence according to the same time index. The state sequence records three elements of sampling time, voltage sample and current sample in a structured manner. To facilitate subsequent interval determination and compensation generation, the protection threshold aperture is written into the protection register of the local critical device at the same time as the state sequence is formed, which is used for subsequent reference; and the power target aperture and the timestamp are recorded together in the head metadata area of the state sequence, which is used as a unified input identifier for subsequent processing. Thus, the input of this step is the initialization completion flag and the control initial value, and the output is the state sequence; wherein the state sequence will be used in the next step to calculate the state of charge and the interval index, and the power target aperture recorded in the head metadata area of the state sequence is referenced in the subsequent control synthesis, forming a consistent link with the previous parameters.

[0065] After obtaining the state sequence, first read its head metadata area, check whether the timestamp and collection period are consistent with the task scheduling criterion, if there is deviation, according to the data integrity rule, fill or cut, make the current processing window and the scheduling window one by one. Specifically, according to the current sample in the state sequence, the available capacity is estimated, and the time index is combined to form the capacity accumulation quantity changing with time; at the same time, according to the voltage sample in the state sequence, the open circuit trend is approximately restored, and the equivalent static voltage corresponding to the current working condition is obtained, which is used as the auxiliary reference of the state of charge. The capacity accumulation quantity and the equivalent static voltage are paired and fused under the unified time index to obtain the state of charge estimation, which is expressed in percentage scale as the relative proportion of the current available capacity, and has one-to-one corresponding time index with the state sequence. In order to enable the subsequent control link to use different parameter sets according to different working conditions, after obtaining the state of charge, interval judgment and marking are carried out immediately: according to the pre-set several continuous intervals in the segmented parameter control table, the interval attribution judgment of the state of charge landing point is carried out, and the interval index is formed by adding the interval mark at each time index; when the state of charge is near the boundary of the interval, the interval switching is delayed according to the hysteresis rule, so as to avoid frequent jumping near the boundary. After completing the interval judgment, the sequence of state of charge with time and the sequence of interval index with time are output together, and they are written into the extended area of the state sequence, so that the subsequent steps can be directly retrieved in the same data container. Understandably, the interval index is used to select the parameter item from the segmented parameter control table in the subsequent control synthesis, and the state of charge is read as a necessary reference quantity in the subsequent compensation quantity generation and power bandwidth monitoring; therefore, the input of this step is the state sequence, the output is the state of charge and the interval index, and the extended area is filled back to the state sequence, which provides data continuity for direct reference of the next step.

[0066] After the calculation of the state of charge and the interval index is completed, the state sequence containing the voltage sample and the current sample, and the state of charge and the interval index backfilled to the extended area in the previous step are read to construct an evaluation dataset corresponding to the current processing window. Specifically, first, the voltage sample and the current sample of the reference time point and the current time point are located in the state sequence, and the reference time point is determined according to the initial timestamp and the scheduling window in the task configuration set, which is used to reflect the voltage level at the start of the current core capacity task; then, in combination with the change amount of the state of charge, the voltage difference between the reference time point and the current time point is attributed to attenuation, which distinguishes between transient changes introduced by load fluctuations and slow changes introduced by capacity degradation, so that subsequent compensation is established on the basis of voltage attenuation related to capacity. After the attenuation attribution is completed, the current parameter interval is determined in combination with the interval index, and the compensation mapping entry corresponding to the interval in the segmented parameter control table is retrieved; in order to avoid discontinuous jumps in the compensation amount of different time windows, a hysteresis reference to the interval of the previous window is introduced during mapping retrieval, and if the interval does not switch, the mapping entry of the previous window is used, otherwise the switching is delayed once according to the hysteresis rule. After obtaining the mapping entry, the voltage attenuation amount is mapped and calculated with the mapping entry to obtain a compensation amount base value matched with the current window; in order to make the compensation amount consistent with the execution caliber of the current power target caliber, the power target caliber in the head metadata area of the state sequence is read, and the compensation amount base value is scaled according to the execution caliber, so that the final compensation amount can be directly used as the input of subsequent control synthesis. After the scaling is completed, a complete integrity check is performed on the data quality: if there is a missing in the state sequence in the current window, the missing segment is filled according to the breakpoint continuation rule recorded by the communication robustness strategy; if the state of charge jumps rapidly near the boundary, the compensation amount is smoothed according to the hysteresis rule to reduce the mutation between different windows. The result after verification and smoothing is set as the feedforward compensation amount, and the feedforward compensation amount is written into the control input area of the state sequence, while a one-to-one correspondence between the time index and the interval index is established, ensuring that the parameter entry can be selected according to the interval and the feedforward compensation amount paired with it can be read synchronously in the subsequent control synthesis. Thus, the input of this step is the state sequence and the state of charge, and the output is the feedforward compensation amount; the feedforward compensation amount and the interval index will be read together for control synthesis by the subsequent control step, and the state sequence continues to be read by the subsequent thermal management and protection judgment for temperature-related and threshold-related judgments, thereby maintaining consistent reference paths in both data container and parameter container levels.Understandably, after the completion of the feedforward compensation amount write, the state sequence has three types of input elements for controlling synthesis, heat-power linkage and protection determination, corresponding to power-related, interval-related and threshold-related processing branches respectively; in the subsequent control synthesis, the interval index is used to select the segmented parameter control table item, and the feedforward compensation amount and the table item jointly form the duty cycle calculation synthesis input, and the output deviation of the synthesis input will be read by the heat management for the arrangement of the power write instruction, forming a continuous execution chain composed of parameter area, data area and control area. In summary, the three sub-steps of step 200 form a closed loop in the input-output relationship: the initialization completion flag and the control initial value enter the collected state sequence, the state sequence is processed to obtain the state of charge and the interval index, the state sequence and the state of charge are evaluated to obtain the feedforward compensation amount, and finally the same data container form is provided for subsequent control synthesis, heat dissipation cooperation and three protection direct calling, so as to keep consistent with the subsequent control execution in terms and fields.

[0067] S3: Select a segmented parameter control table item based on the interval index and the hysteresis rule, combine the feedforward compensation amount to perform duty cycle calculation and power deviation processing based on the power error signal and integral limiting, and generate a compact flag;

[0068] After the collection and calculation are completed, the control execution unit first sequentially reads the interval index from the extended area of the state sequence, and performs consistency checking on the time index of each current processing window, so that the interval index corresponds to the time index of the state sequence. Specifically, the control execution unit defines the start and end positions of the current processing window according to the task scheduling criterion written in the initialization stage; then, the interval index is used as a search key to locate the corresponding parameter entry from the locally stored segmented parameter control table. The segmented parameter control table is organized according to the continuous interval of the state of charge, and each parameter entry contains fields such as proportional parameter, integral parameter, derivative parameter, integral limit, jitter suppression threshold, power allowable bandwidth, duty cycle constraint boundary, and hysteresis switching threshold, and records the entry version and effective period. To ensure the stability of interval switching, before the target entry is retrieved, the control execution unit first reads the parameter entry selected by the previous processing window and its hysteresis switching threshold, compares the current interval index with the interval marker of the previous processing window, and when the hysteresis condition is met, the original parameter entry remains unchanged, and when the switching condition is met, the new parameter entry is updated. To avoid retrieval failure caused by missing entries or inconsistent versions, the control execution unit performs integrity checking and version checking on the segmented parameter control table, and if a missing entry is found, a backup table item is called, and if the version is found to be behind the version number of the task configuration set, a one-time synchronization is triggered and the replacement is completed before the end of the window. After the entry is determined, the control execution unit generates the execution boundary of the current window according to the power allowable bandwidth and the duty cycle constraint boundary, and loads the proportional parameter, integral parameter, derivative parameter and integral limit to the local fast register area for subsequent control synthesis call. At the same time, in order to maintain consistent criteria in subsequent thermal and power linkage, the control execution unit mirrors the power allowable bandwidth of the current window to the shared area of the temperature management unit, ensuring that when a power write-back instruction needs to be generated, the same boundary can be directly referenced. Thus, the input of S310 is the interval index and the segmented parameter control table, and the output is the segmented parameter control table item matched with the current processing window, and the execution boundary and shared mirror are generated locally to provide a complete parameter set for the control synthesis of the next step.

[0069] After obtaining the segmented parameter control table, the control execution unit reads the feedforward compensation corresponding to the current time index from the control input area of the state sequence, and uses the proportional parameter, integral parameter, and differential parameter just loaded, together with the integral limit, as inputs for control synthesis. At the same time, the power target caliber and time reference are read from the state sequence header metadata area to ensure that the control calculation is performed under unified caliber and unified tempo. Specifically, the control execution unit first generates the power error signal of the current period according to the power target caliber, the voltage sample at the current time index, and the current sample; then calls the proportional integral differential control link to perform component decomposition and limit accumulation on the power error signal, and the integral component is subjected to upper and lower boundary constraints under the action of the integral limit, and the differential component is subjected to mutation suppression under the action of the jitter suppression threshold; after obtaining the three types of components, the control execution unit superimposes the feedforward compensation on the control link synthesis quantity in the same execution caliber, so that the feedforward part pre-compensates the trend quantity of voltage attenuation, and the feedback part corrects the instantaneous error. To ensure that the duty cycle calculation result meets the execution boundary, the control execution unit performs boundary mapping on the synthesis quantity, and clips the part exceeding the duty cycle constraint boundary to the allowed interval; after mapping is completed, the duty cycle of the current time index is obtained, and the power deviation is calculated according to the power target caliber of the current period, the current voltage sample, and the current sample, and the power deviation is compared with the power allowed bandwidth to obtain the instant judgment of the bandwidth position. To avoid excessive fluctuations in the control quantity between adjacent time indexes, the control execution unit applies a time-adjacent smoothing strategy to the duty cycle sequence, and when the difference between two adjacent time indexes exceeds a threshold, it transitions by a preset gradual step; at the same time, the updated duty cycle is written into the execution buffer for the power device to use when the next timing interrupt comes. In this step, the control execution unit also records the relative relationship between the power deviation and the power allowed bandwidth as three state marks of in-band, close to the band boundary, or out-of-band, and appends the state mark to the extension area of the state sequence for bandwidth judgment and compact processing call in the next step. Thus, the input of S320 is the segmented parameter control table, the feedforward compensation, and the samples and metadata related to the current period in the state sequence, and the output is the duty cycle and the power deviation, and the state mark is formed in the extension area to provide a direct basis for generating a compact flag subsequently.

[0070] After the calculation of the duty cycle and power deviation, the control execution unit obtains the state flag written in the last step and the power deviation and power allowed bandwidth of the current window, and determines the bandwidth of the power deviation in the time dimension. Specifically, the control execution unit slides the power deviation of a plurality of continuous time indexes in the current processing window to determine the proportion of the power deviation located in the bandwidth, close to the bandwidth boundary or out of the bandwidth, and determines the bandwidth state of the current window by combining the historical statistical value of the adjacent window and the hysteresis rule. When the statistical result shows that the power deviation is close to the bandwidth boundary at a considerable proportion of time indexes, the control execution unit starts the compact processing procedure: first, read the jitter suppression threshold and integral clipping in the segmentation parameter control table item, appropriately tighten the upper and lower boundaries of the integral clipping, so that the accumulation rate of the integral component to small deviation is reduced; then, without changing the power target aperture, an incremental compression strategy is applied to the duty cycle sequence, the incremental compression strategy limits the variation amplitude of the duty cycle of a plurality of future time indexes by a fixed step, and ensures that the compressed duty cycle is still within the duty cycle constraint boundary, so that the time adjacent difference of the control output is kept within the controlled range. If the statistical result shows that the power deviation is out of the bandwidth, the update of the boundary mapping parameter of the current window is triggered at the same time on the basis of the compact processing, so that the upper limit or lower limit of the subsequent duty cycle mapping is appropriately converged; if the statistical result shows that the power deviation is long-term located in the bandwidth, the compact processing is maintained in the minimum state, and only the temporary suppression of the burst jitter is reserved. In order to realize the closed loop with the subsequent heat and power linkage, the control execution unit generates a compact flag after each compact processing is completed, the compact flag records whether the compact processing is effective, the level of the compact processing and the time window number of the duration, and writes the compact flag in the extension area of the state sequence in a unified format, and mirrors to the shared area of the temperature management unit, so that the subsequent power write-back instruction can be generated in combination with the compact flag and the heat state to determine whether the derating or recovery is needed. In order to maintain the consistency with the event record, the control execution unit also writes the trigger time, processing level and duration of the compact processing into the local event cache for subsequent unified reading and reconstruction of the time axis by the recording and archiving steps. Finally, the control execution unit summarizes the effective state of the compact flag at the end of the current processing window, and adapts the initial parameters of the next processing window, so that the level of the compact processing and the incremental compression strategy can be smoothly continued without switching the interval; when the interval is switched and the hysteresis rule is met, the level of the compact processing is automatically released or adjusted to match the new parameter item. Therefore, the input of S330 is the power deviation, the power allowed bandwidth, the segmentation parameter control table item and the state flag generated in the last step, the output is the compact flag, and the compact flag is transmitted to the heat and power linkage step through the mirroring mechanism of the shared area, and the original basis is provided for the subsequent recording and archiving steps through the event cache.Understandably, the segment parameter control table item generated in S310 is directly used to control synthesis in S320, the duty cycle and power deviation generated in S320 is used for bandwidth determination and compact processing in S330, the compact flag generated in S330 is read for generating power write-back instructions in the subsequent process of heat dissipation adjustment according to the three-segment threshold and hysteresis logic, and is read for constructing time axis entries and participating in parameter write-back in the process of protection determination and report archiving; thereby establishing a continuous link from selection, synthesis to constraint and mirroring between the parameter table, the control quantity and the linkage flag. In general, the running process of S310 to S330 forms a closed loop at the input and output level: the interval index drives the determination of the parameter entry, the segment parameter control table item and the feedforward compensation quantity jointly complete the calculation of the duty cycle and the power deviation, the power deviation generates the compact flag after bandwidth determination and compact processing, and provides unified trigger quantity and record quantity for subsequent heat dissipation cooperation, threefold protection and report archiving, so that the control parameters, the execution quantity and the linkage quantity remain consistent reference and continuous transmission in the same data container.

[0071] S4: adjusting the cooling liquid flow and the refrigeration power based on the three-segment threshold and the hysteresis logic according to the compact flag to obtain a thermal state, generating a power write-back instruction based on the power allowed bandwidth and the duty cycle constraint boundary and issuing a confirmation to obtain a write-back confirmation flag;

[0072] At the input of the present step, the heat dissipation coordination unit first acquires temperatures from the temperature acquisition channel, including the power device shell temperature, the heat exchange plate center temperature, the cooling liquid inlet temperature, and the cooling liquid outlet temperature, and aligns the sampling time with the task scheduling interval. At the same time, the compact flag generated by the previous step is read from the shared area to represent whether the control output has entered the compact processing level. Specifically, the heat dissipation coordination unit constructs a temperature judgment window according to the three threshold values registered in the task configuration set and the hysteresis logic, and judges the above-mentioned temperatures in sections: when the temperature is below the first threshold value, it is judged as the basic heat dissipation section; when the temperature is between the first threshold value and the second threshold value and does not exceed the second threshold value, it is judged as the enhanced heat dissipation section; when the temperature exceeds the second threshold value or the thermal pressure represented by the temperature difference continues to rise to the vicinity of the third threshold value, it is judged as the intensive heat dissipation section; when the temperature falls back and meets the corresponding fall-back threshold, it exits to the previous section according to the hysteresis logic to eliminate frequent jitter. In order to keep the time reference of heat dissipation control consistent with the control output, the heat dissipation coordination unit first calculates the temperature difference between the cooling liquid inlet and outlet in each processing window, and adjusts the water pump speed and valve opening degree linearly or in sections according to the temperature difference. When it is judged to enter the enhanced heat dissipation section or the intensive heat dissipation section, the refrigeration power ratio of the refrigeration unit is also increased, and the current heat dissipation working level and the continuous window number are registered in the shared area. Further, when the compact flag indicates that the control output is in compact processing, the heat dissipation coordination unit sets a more conservative climbing step for the water pump speed and the refrigeration power under the same temperature difference, and sets a longer delay window for the fall-back path, so that the heat dissipation and the compact processing form a cooperative relationship, avoiding the reverse mutation of the heat dissipation side in the control output convergence process. In order to ensure that the power write-back instruction generated subsequently can directly reference the unified criterion, the heat dissipation coordination unit, at the end of the current processing window, solidifies the comprehensive judgment based on the three threshold values and the hysteresis logic into a heat state, which records the heat dissipation working level, the hysteresis position, the continuous window number, and the temperature difference statistics, and writes it into the extension area of the state sequence, and at the same time synchronizes to the shared area of the power control side in a mirror image manner. Thus, the input of the present step is the temperature and the compact flag, and the output is the heat state, which is consistent with the index of the previous state sequence, the power allowed bandwidth, and the compact processing record, facilitating direct retrieval and use in the next step.

[0073] After the generation of the thermal state is completed, the power linkage unit reads the thermal state from the shared area and reads the power deviation paired with the current time index from the extension area of the state sequence, while obtaining the power allowed bandwidth and the duty cycle constraint boundary mirrored by the parameter selection step as the scheduling reference. Specifically, the power linkage unit first parses the thermal state in a window granularity: when the thermal state corresponds to the basic heat dissipation segment, only a tracking queue is established to record the subsequent possible state changes, and no adjustment is made to the power target caliber; when the thermal state corresponds to the enhanced heat dissipation segment, in the case where the power deviation is close to the power allowed bandwidth boundary, a first-level power write-back instruction item is generated, which includes four types of fields of target correction amount, duration window number, release condition and slope limit, wherein the target correction amount is generated according to the relative position of the power deviation and the power allowed bandwidth, the duration window number and the release condition are determined according to the hysteresis position of the thermal state, and the slope limit is set according to the remaining margin of the duty cycle constraint boundary; when the thermal state corresponds to the strengthened heat dissipation segment or the temperature difference statistic continuously rises and reaches the vicinity of the third threshold, a second-level or multi-level power write-back instruction item is superimposed, and the release condition is set as the window number of the thermal state falling back to the previous segment and continuously satisfying the falling back threshold, so as to ensure that the power write-back instruction is maintained effective before the heat dissipation load is relieved. In order to make the power write-back instruction consistent with the time tick of the control synthesis, the power linkage unit aligns and de-duplicates all the items, if the trigger conditions of different levels are met at the same time in the same window, the items are merged into a single instruction according to the priority of the items, and the reference identifier of the merged items is recorded for subsequent event reconstruction. Further, when the thermal state falls back and the release condition is met, the power linkage unit generates a recovery item, reverses the sign of the target correction amount and sets a gradual recovery step, so that the change speed of the recovery process is controlled by the slope limit; if the compact flag is still in the effective state, the step of the recovery item is proportionally converged, so that the recovery process and the compact processing keep the same direction evolution. After the scheduling is completed, the power linkage unit encapsulates all the items into the power write-back instruction, which records the target correction amount, the duration window number, the release condition, the slope limit, the applicable interval index and the reference identifier in a structured format, and establishes a one-to-one association relationship with the time index of the current window, and is written into the shared area for the control unit to pull and execute. Thus, the input of this step is the thermal state and the power deviation, and the output is the power write-back instruction, which maintains the consistent caliber with the power allowed bandwidth, the duty cycle constraint boundary and the compact flag, so that the subsequent parameter update and confirmation can be completed in a single session.

[0074] After obtaining the power backwrite instruction, the control interface unit establishes an instruction channel with the control unit according to the communication robustness strategy, and writes the version number of the task configuration set and the time index of the current window in the session header; then writes the power backwrite instruction into the parameter area of the control unit in field order, including the target correction amount, the number of continuous windows, the release condition, the slope limit, and the applicable interval index, etc. fields, while retaining the reference identifier for subsequent event alignment. Specifically, the control interface unit first sends a write request, and the control unit checks the instruction structure after receiving it. If it finds that the fields are missing or out of bounds, it returns an exception marker and requests retransmission. The control interface unit triggers the breakpoint resume transmission accordingly, and only supplements the fields that do not pass the check. When all fields pass the check, the control interface unit issues an activation request, and the control unit loads the target correction amount and the slope limit into the fast register area, registers the number of continuous windows and the release condition in the scheduling table, and binds them with the interval index to ensure that the power backwrite instruction takes effect within the corresponding interval. To ensure the uniformity of the execution boundary, the control unit reads the power allowed bandwidth and the duty cycle constraint boundary mirrored by the parameter selection step before activation. If the target correction amount of the power backwrite instruction may cause the subsequent duty cycle to exceed the boundary, the control unit performs a boundary mapping on the correction amount locally and writes the mapping result back to the instruction buffer. After completing the mapping, the control unit returns an activation reply, including the activation time, the boundary mapping result, and the bound interval index. After receiving the activation reply, the control interface unit performs a time alignment, maps the reply time with the time index of the current window, and writes the mapping together with the activation reply into the extended area of the state sequence, while generating a backwrite confirmation marker in the shared area. The backwrite confirmation marker records the session number, the activation time, the mapping result, and the instruction reference identifier. Further, to facilitate subsequent protection judgment and report archiving, the control interface unit writes the number of retransmissions, the breakpoint resume paragraph number, and the exception marker that occur in this session into the event cache for subsequent record step reading; at the same time, the backwrite confirmation marker is notified to the heat dissipation coordination unit for evaluating the cooperation between the thermal state and the power backwrite instruction in the next window. Thus, the input of this step is the power backwrite instruction, and the output is the backwrite confirmation marker, which is provided to the protection judgment and data archiving branches at the same time through the dual-writing mechanism of the state sequence extension area and the shared area, ensuring that the subsequent emergency stop judgment can refer to the latest instruction effective information, and the report archiving can reconstruct the complete time axis and parameter change link. In summary, the three steps form a continuous link in the input and output level: the temperature and the compact flag generate the thermal state in the first step, the thermal state and the power deviation generate the power backwrite instruction in the second step, and the power backwrite instruction completes parameter update and confirmation and forms the backwrite confirmation marker in the third step, thereby providing synchronous input for the protection judgment branch and the data archiving branch, so that the heat dissipation adjustment, power target correction, and execution confirmation run in a closed loop under the unified time index and parameter caliber.

[0075] S5: generating emergency stop flag based on thermal state and state sequence, sorting event records based on time index coupling relationship and generating recovery procedure guide based on guide template;

[0076] Upon entering this step, the protection determination unit first reads the thermal state from the shared area, and extracts voltage samples and current samples and corresponding time indexes from the state sequence according to the current processing window, so that the temperature side and the electrical parameter side are aligned under the same scheduling caliber. Specifically, the protection determination unit performs boundary check and transient discrimination on the current samples according to the protection threshold caliber and sampling beat registered in the task configuration set: when the current sample exceeds the overcurrent threshold within a plurality of consecutive time indexes, or a sudden increase occurs within a single time index and the duration exceeds the minimum holding time slot, the index segment is marked as an overcurrent candidate segment; for the temperature side, read the heat dissipation working level, hysteresis position and temperature difference statistics in the thermal state, if the heat dissipation working level is in the intensive heat dissipation segment and lasts for more than a set window number, or the temperature difference statistics shows a continuous upward trend and exceeds the temperature threshold upward threshold, the processing window is marked as an overtemperature candidate segment; for the voltage side, combined with the voltage samples of the state sequence and the voltage trend of the previous window, if the voltage sample is below the undervoltage threshold and has not recovered within the hysteresis fall threshold, or the voltage sample plunges sharply within a short time and the plunge amplitude exceeds the undervoltage rate threshold, the processing window is marked as an undervoltage candidate segment. Further, to eliminate the influence of single accidental disturbance on the determination, the protection determination unit performs consistency review on the three types of candidate segments: cross comparison between the candidate segment and the continuous window number in the thermal state, only when the candidate segment and the continuous window number overlap, and the voltage sample or current sample still meets the corresponding threshold condition in the overlapping interval, the candidate segment is upgraded to an effective alarm segment; for overtemperature and overcurrent occurring at the same time, the overtemperature is disposed first according to the priority table in the task configuration set, and then the overcurrent is reviewed to avoid repeated reporting. After consistency review, the protection determination unit generates an emergency stop flag according to the type of the effective alarm segment, the emergency stop flag contains fields such as alarm type, trigger time index, related channel, continuous window number and corresponding interval index, and is written into a read-only mapping in the extension area of the state sequence for subsequent event generation step to directly retrieve; at the same time, the emergency stop flag is notified to the local control unit in a synchronous manner, for triggering the local emergency stop branch and the supply side trip linkage, to ensure that the state is consistent before parameter updating and recording. Thus, the input of this step is the thermal state and the state sequence, and the output is the emergency stop flag, and the index alignment and field solidification are completed in the data container, providing sufficient basis for the time axis sorting and event construction of the next step.

[0077] After the emergency stop mark is generated, the event construction unit reads the write-back confirmation mark formed by the previous step from the shared area and performs field-level pairing with the currently obtained emergency stop mark. Specifically, the event construction unit takes the time index as the primary key, maps the trigger time index in the emergency stop mark with the activation time in the write-back confirmation mark, and if both cross the same processing window, determines that they are same-window coupled events; if both are in adjacent windows and the difference does not exceed the maximum tolerance window number defined by the scheduling caliber, determines that they are adjacent coupled events; otherwise, marks them as independent events and records the cross-window offset. Subsequently, the event construction unit assembles event records around the coupling relationship: when there are same-window coupled events, the boundary mapping results in the write-back confirmation mark are merged into the event record with the applicable interval index to fully present the parameter side change link before and after the emergency stop trigger; when there are adjacent coupled events, the snapshots of the slope limit, the number of continuous windows, and the release condition are appended to the fields, so that the subsequent recovery process can be arranged based on the real issuance state; when it is an independent event, only the core fields of the emergency stop mark are retained, and the independent reason is written in the event record, prompting the subsequent archiving step to adopt a conservative strategy when generating the recovery process guide. To ensure the continuous reconstructability of the time axis, the event construction unit sorts all event records in time order and merges multiple source triggers within the same time index: if there are both over-temperature and over-current in the same index, the primary cause is written into the main event field according to the priority table, and the secondary cause is written into the auxiliary cause field; if there is also an abnormal reply from the communication side in the same index, the number of retransmissions and the breakpoint continuation paragraph number are written in the event annotation, so that the subsequent link robustness strategy can be reviewed. After sorting and merging, the event construction unit assigns a unique serial number to each event record and establishes a bidirectional index with the original sample area of the state sequence, so that the subsequent archiving can quickly trace back to the corresponding voltage sample and current sample and the temperature side continuous window number. Thus, the input of this step is the emergency stop mark and the write-back confirmation mark, and the output is the event record, which is saved in the event cache in a structured format and is simultaneously written into the extended area of the state sequence, providing standardized input for the archiving and guide generation of the next step.

[0078] After the event record is formed, the archiving and guiding unit calls the event cache, sequentially reads each event record, and cross-checks the time index, the main cause and auxiliary cause, the boundary mapping result, and the applicability interval index with the original sample area of the state sequence. Specifically, the archiving and guiding unit first performs structured segmentation on the event record: writes the main event field, the auxiliary cause field, the parameter snapshot, and the link note into the archiving entry, and establishes a multi-level directory with the time index as the primary key and the event unique serial number as the secondary key; then, according to the event type, the corresponding guide template is selected, for the over-temperature event, the heat dissipation working level, the hysteresis position, and the number of continuous windows are extracted from the event record, combined with the boundary mapping result and the slope limit, to generate the derating reservation paragraph, the heat dissipation rollback monitoring paragraph, and the recovery step paragraph; for the over-current event, the relative position of the current channel and the power allowed bandwidth is extracted from the event record to generate the duty cycle limit paragraph, the sampling beat review paragraph, and the short-term retest paragraph; for the undervoltage event, the down amplitude of the voltage sample and the interval index are extracted from the event record to generate the cutoff threshold review paragraph, the charging window coordination paragraph, and the re-capacity scheduling paragraph. To ensure that the recovery process guide can be directly referenced in subsequent data arrangement and plan rewriting, the archiving and guiding unit arranges the above paragraphs into a single recovery process guide according to the execution order, which specifies the trigger condition, execution object, continuous window number, and exit condition of each paragraph, and appends a placeholder field for the plan update suggestion at the end for subsequent rewriting steps to fill in. Further, the archiving and guiding unit starts the synchronization mechanism: the archiving entry and the recovery process guide are synchronized to the operation side and the control side respectively, the operation side is used for subsequent report data generation and time axis display, and the control side is used for actual arrangement of derating and recovery in the next task period; after synchronization is completed, the archiving and guiding unit writes a guide completion marker in the shared area, and records the guide version and the corresponding event unique serial number in the extension area of the state sequence, ensuring that any recovery process guide read subsequently can be traced back to the original event. At this point, the input of this step is the event record, and the output is the recovery process guide, which is indexed by the archiving directory and the guide version to achieve seamless connection with the report generation step and the task configuration rewriting step. In summary, the three steps form a closed loop in the input and output level: the hot state and the state sequence generate the emergency stop marker in the first step, the emergency stop marker and the rewriting confirmation marker generate the event record in the second step, and the event record is archived and converted into the recovery process guide in the third step; the recovery process guide is then used for data arrangement and plan update, so that the protection judgment, event construction, and guide generation are continuously transmitted and traceable under the unified time index and parameter caliber.

[0079] S6: Check and fill data based on sampling time and breakpoint resume rule from the recovery process guide and the state sequence, generate structured report data based on the capacity measurement caliber, adjust the task configuration set and obtain the adjustment parameter set based on the curve segment set and the change segment set.

[0080] Upon entering this step, the data compilation unit first acquires the recovery process guide from the shared area according to the time index, and extracts the voltage samples, current samples, temperature samples, and interval indexes, duty cycle records, power allowable bandwidth records, and write-back confirmation marks within the corresponding time range from the state sequence, so that the recovery process guide and the state sequence are aligned under the same scheduling caliber. The data compilation unit establishes a window-level input set accordingly, and the input set explicitly specifies the sampling time, channel identifier, and sampling time for each window. Specifically, the data compilation unit performs data integrity checking on the above input set according to the sampling time and link robustness strategy registered in the task configuration set: for each window, check whether the voltage samples and current samples are complete item by item, if there is a missing segment, retrieve and splice the breakpoint resume segment adjacent to the window in the event cache; perform pairing check on the inlet and outlet readings of the temperature samples, and perform consistency review with the heat dissipation working level recorded in the recovery process guide, if the heat dissipation working level is not consistent with the temperature difference trend, mark the abnormality in the original sample and trigger the adjacent window backtracking. To avoid time drift caused by cross-site synchronization, the data compilation unit performs a clock calibration with session number and time index as primary keys, and only allows correction for windows without write-back confirmation marks during the calibration process; if there is a write-back confirmation mark in the window, the original time is retained and a fixed identifier is registered in the calibration result to ensure accurate positioning of the parameter effective time during subsequent curve generation. After the above checking is completed, the data compilation unit implements missing data filling for windows that still have blanks: when the missing data only occurs in a single channel and the adjacent window sample changes continuously, fill in the missing data by adjacent window interpolation and add a filling identifier; when the missing data involves multiple channels or there is a mutation in adjacent windows, extract parameter snapshots from the control side write-back cache of the same time index according to the execution paragraph of the recovery process guide, set the filling window to read-only snapshot and block derivation to avoid introducing uncertain calculations; when the missing data involves communication side interruption and the event record marks the retransmission number and paragraph number, preferentially merge the retransmission segment and cancel the same window interpolation. Finally, the data compilation unit aggregates all types of samples, interval indexes, duty cycle records, power allowable bandwidth records, heat dissipation working levels, and write-back confirmation marks after checking and filling to form a complete data set, and establishes a directory with time index as the primary key and channel identifier as the secondary key. The directory item saves the filling identifier and the calibration identifier as the unique input for generating curves and lists in the next step.

[0081] After obtaining the complete data set, the curve and list generation unit traverses the directory according to the time index, merges the voltage samples and current samples in the same window according to the power caliber, calculates the temperature difference between the inlet and outlet of the temperature samples, and aligns the duty cycle record and the power allowable bandwidth record by window to form the curve element set. Specifically, the curve and list generation unit first accumulates and arranges the curve element set according to the capacity measurement caliber registered in the task configuration set to generate the basic sequence of the core capacity curve; when the directory item contains a supplement identifier, the supplement interval is distinguished by a dashed line or a mark in the basic sequence; when the directory item carries a write-back confirmation mark, the parameter effective identification is written in the basic sequence, so that the start and end positions of the parameter change can be accurately presented on the subsequent time axis. Subsequently, the curve and list generation unit extracts the parameter snapshot and interval index associated with the paragraph from the complete data set based on the execution paragraph in the recovery process guide, generates a parameter change list according to the execution order of the paragraph, and lists the target correction amount, the number of continuous windows, the release condition, the slope limit and the applicable interval index in the parameter change list one by one; if there are multiple parameter snapshots in the same time index, they are merged according to the priority table, and the reference identifier of the merged item is retained in the list. In order to improve the consistency of subsequent retrieval, the curve and list generation unit performs structured processing on the core capacity curve and the parameter change list: the curve basic sequence, the supplement interval and the parameter effective identification are combined into a curve segment set, and the interval index and the heat dissipation working level at the time of generation are associated with each curve segment; the parameter change list is sorted by time and interval, a change segment set is generated, and a bidirectional index is established with the curve segment set to ensure that any paragraph can be traced back to the original window and directory item. Further, the curve and list generation unit samples the curve segment set and the change segment set with the original sample area of the state sequence, compares the combination trend of the voltage sample and the current sample with the boundary relationship of the power allowable bandwidth record in the sampling window, and if there is a discrepancy, inserts a check note in the draft report and marks the window number that needs to be reviewed. Finally, the curve and list generation unit packages the core capacity curve and the parameter change list together with the sampling check note into report data, saves the report data in a structured format, includes the curve segment set, the change segment set, the index mapping, the check note and the directory pointer, and registers the report version in the shared area to provide standardized input for the write-back and update of the next step.

[0082] After the report data is generated, the planning and writing unit loads the report version from the shared area and reads the curve segment set and the change segment set in turn, while extracting the current target power, cutoff voltage, time length, sampling beat and link robustness strategy from the task configuration set, so that the writing and updating are executed under the same version caliber. The planning and writing unit first determines the new parameters that need to be solidified and the temporary parameters that need to be revoked according to the parameter effective identification in the change segment set: when the release condition of a change segment has been met and the temperature difference trend has fallen within the hysteresis fall threshold within the time range corresponding to the curve segment set, the change segment is marked as revocable, and a revocation entry is generated in the writing queue; when the target correction amount of a change segment is continuously stable in the curve segment set and consistent with the power allowed bandwidth record boundary, the change segment is marked as solidifiable, and a solidification entry is generated in the writing queue. Subsequently, the planning and writing unit performs a quick review on the window number marked for review according to the sampling check note in the report data: if the review window involves communication side retransmission information, a feedback strategy entry is appended to the writing queue, requiring higher level feedback and retransmission configuration to be enabled for the corresponding link in the next task period; if the review window involves the completion interval, an observation strategy entry is appended to the writing queue, requiring the sampling beat or observation time length of the interval to be increased in the next task period. To ensure the timing consistency of parameter writing and plan updating, the planning and writing unit sorts all entries according to execution priority: first execute the revocation entry, then execute the solidification entry, and finally execute the feedback strategy entry and the observation strategy entry; the execution of each entry is anchored by session number and time index, and a corresponding writing confirmation mark is generated after the execution is completed, which is one-to-one bound with the entry and written into the shared area. After the above writing is completed, the planning and writing unit updates the plan according to the capacity trend of the report data and the duration window number of the parameter change list: for the interval that needs to be re-capped, a new task time window is generated according to the interval index and the end position of the curve segment set; for the interval that needs to be started at a reduced capacity, new target power and change step are generated according to the target correction amount and slope limit of the change segment set; for the interval that needs to adjust the cutoff condition, new cutoff voltage and protection boundary are generated according to the downward amplitude in the curve segment set; and new sampling beat suggestion is given for the interval involving observation strategy. Finally, the planning and writing unit aggregates all the executed and updated parameter entries into an adjustment parameter set, which records the curve segment or change segment reference identification, execution result and writing confirmation mark of each entry, and establishes a version mapping relationship with the original entry of the task configuration set; at the same time, the planning and writing unit registers the adjustment parameter set version in the shared area, so that the next task period can refer to the results of this update when reading the task configuration set.In summary, the input of this step is report data, and the output is a set of adjustment parameters. The complete dataset drives the formation of report data, which is then transformed into a set of adjustment parameters after being written back and updated. This set establishes a stable index relationship with the preceding task configuration set, status sequence, and recovery process guidelines, thereby forming a continuous closed loop from data compilation to curve and list generation, and then to parameter write-back and plan update, all within the same index and parameter caliber at the same time.

A sliding statistical determination and a gradual compression strategy processing are performed on the power deviation to obtain the compact flag. The compact flag is output to the thermal regulation and instruction module for registration, and a state marker is returned to an extension area of the state sequence.

Specifically, the thermal regulation and instruction module 105 receives the compact flag from the control synthesis module and temperature data from a temperature acquisition channel, adjusts the water pump speed, the valve opening degree, and the refrigeration power to obtain the thermal state. Based on the thermal state and the power deviation, a first derating item and a second derating item of the power write-back instruction are generated. The power write-back instruction is issued to a control unit for parameter updating and confirmation, and the write-back confirmation marker is obtained. The write-back confirmation marker is transmitted to the safety determination and event processing module.

[0089] The safety determination and event processing module 106 is configured to perform overcurrent, overtemperature, and undervoltage determination based on the thermal state and the state sequence to generate an emergency stop marker, sort event records, and generate a recovery process guide. Specifically, the safety determination and event processing module 106 receives the thermal state from the thermal regulation and instruction module and the state sequence from the data acquisition and state calculation module, performs transient discrimination and consistency review on overcurrent threshold, temperature threshold, and undervoltage threshold, and generates the emergency stop marker. Based on the emergency stop marker and the write-back confirmation marker, event merging and field assembly are performed to obtain the event records. The event records are divided into archiving items and arranged into recovery paragraphs to generate the recovery process guide. The recovery process guide is transmitted to the data compilation and parameter updating module.

[0090] The data compilation and parameter updating module 107 is configured to check and supplement data from the recovery process guide and the state sequence, generate structured report data, and adjust a task configuration set to obtain an adjustment parameter set. Specifically, the data compilation and parameter updating module 107 receives the recovery process guide and the state sequence from the safety determination and event processing module, performs data integrity checking and missing supplementing to form a complete data set. Based on the complete data set, a nuclear capacity curve basic sequence and a parameter change list are generated, and structured processing of curve segment sets and change segment sets is performed to obtain report data. According to the report data, the target power, the cutoff voltage, and the time length of the task configuration set are adjusted to obtain the adjustment parameter set. The adjustment parameter set is written back to the parameter configuration and issuing module for use in the next task period.
