Description

Technical Field

[0001] The present invention belongs to the field of electric power automation and relates to a digital intelligent debugging method for substation automation services and related devices. Background Art

[0002] With the construction of digital power grid, relevant research on the automation test and construction of substation protection, telecontrol, one-button sequential control and anti-error blocking logic has been carried out. At present, research has been carried out on substation commissioning verification, focusing on the automatic test of the one-button sequential control function and the automatic acceptance of equipment signals. At the same time, the SCD model file, anti-error blocking logic and one-button sequential control business models of substation automation include all the interval information of the entire station. Various information is cross-coupled, and the impact range between intervals cannot be determined. This leads to the current single-person single-task on-site power outage method for commissioning and testing operations.

[0003] However, the use of a single-person single-task on-site power outage method for debugging and testing has the following major disadvantages: 1. The single-task debugging method is inefficient. The automatic service debugging of a station generally takes more than 30 days, and the operation cycle is long; 2. On-site power outage debugging affects the operation of the power grid; 3. The on-site work is complex and the operation risk is high. In scenarios such as operation maintenance, renovation and expansion, the operation system operation and security measures are complex, there are many on-site construction areas, and the construction personnel work cross-operation is prominent, there are high equipment and personal risks, and the management cost of the project is increased.

[0025] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0028] See also Figure 1 In one embodiment of the present invention, a digital debugging method for substation automation services is provided, which improves debugging efficiency by performing multi-task collaborative parallel debugging verification, decouples the debugging environment from the on-site physical environment, avoids on-site power outages affecting grid operation, and improves substation automation debugging efficiency.

[0029] Specifically, the digital intelligent debugging method of substation automation service of the present invention includes the following steps:

[0030] S1: According to the digital model information of the substation, the interval-related interface is used as the interface unit to construct the digital debugging clone model of each interface of the substation.

[0031] S2: Through the digital intelligent debugging clone models of each interface of the substation, the independent debugging operation tasks corresponding to the digital intelligent debugging clone models of each interface are executed in parallel.

[0032] S3: The digital debugging clone models of each interface that have completed independent debugging tasks are merged to obtain the digital debugging clone model of the entire substation.

[0033] S4: Execute the whole-station debugging task through the whole-station digital debugging clone model of the substation.

[0034] The digital intelligent debugging method for substation automation business of the present invention first constructs digital intelligent debugging clone models of each interface of the substation based on the digital model information of the substation and with the interval associated interface as the interface unit, and then executes the independent debugging operation tasks corresponding to the digital intelligent debugging clone models of each interface in parallel through the digital intelligent debugging clone models of each interface of the substation. On the one hand, the problem of low efficiency of the debugging method of a single task can be solved by parallel execution, which greatly improves the debugging efficiency; on the other hand, by constructing the digital intelligent debugging clone model of the interface, the debugging verification environment is decoupled from the on-site physical environment, and efficient testing is achieved in the non-power outage scenario, which can avoid the on-site power outage operation affecting the operation of the power grid, eliminate the on-site debugging equipment and personal risks, and reduce the cost of engineering management. Then, the digital intelligent debugging clone models of each interface that completes the independent debugging operation task are merged to obtain the digital intelligent debugging clone model of the whole station of the substation, and the whole station debugging operation task is executed through the digital intelligent debugging clone model of the whole station of the substation, so as to realize the all-round digital intelligent debugging of the substation, and the digital intelligent debugging clone model of the whole station after the debugging is completed can be directly imported into the on-site system to ensure the reliable and stable operation of the substation.

[0035] In a possible implementation, the method of constructing a digital debugging clone model of each interface of the substation based on the digital model information of the substation and taking the interval-associated interface as the interface unit includes: constructing a configuration model of each interval in the substation based on the digital model information of the substation; obtaining the association relationship between intervals across voltage levels in the substation and the association relationship between intervals within the same voltage level based on the digital model information of the substation; obtaining the associated interfaces of each interval in the substation based on the configuration model of each interval in the substation and the association relationship between intervals across voltage levels in the substation and the association relationship between intervals within the same voltage level; constructing a substation clone debugging model based on the digital model information of the substation; and logically decomposing the substation clone debugging model based on the interval-associated interface as the interface unit to obtain the digital debugging clone model of each interface of the substation.

[0036] Explanatory, the substation automation business debugging of newly built stations and expanded stations includes the monitoring system and communication gateway machine at the station control layer, the measurement and control device at the bay layer, and the process layer equipment, involving a series of automation services such as one-button sequential control tickets, interlocking logic, and telemetry and telesignaling points. The debugging and verification of automation business functions involves information within the bay, between different bays, and between different voltage levels.

[0037] Substation automation business debugging only relies on the external interaction characteristic data of the system, equipment or function. Therefore, according to the digital model information of the substation, a digital debugging clone model of each interface of the substation is constructed. The digital debugging clone model of each interface has the function of simulating and cloning the external characteristics of the substation automation business system and equipment, and can analyze the correlation between different voltage levels and different intervals.

[0038] The digital model information of the measurement and control devices and the on-site debugging of the automation monitoring system in the substation system includes SCD model files, RCD files, one-key sequential control operation tickets, interlocking logic files, data record files, database export information files, monitoring screen sequence files and replacement record files.

[0039] The clone model simulates the external characteristics of the substation by importing digital model information, clones the functions of the phenomenal operating system and equipment, ensures that the debugging system functions are consistent with the functions of the on-site operation, and decouples the debugging environment from the on-site physical environment. Clone the on-site debugging system functions and analyze the correlation between different voltage levels of the substation and different intervals within the voltage level.

[0040] Substation commissioning and testing are usually carried out in bays. The existing engineering implementation habit is to divide bays mainly based on primary equipment. The correlation between bays in the entire station is analyzed based on the SCD model file, and the digital intelligent commissioning clone model of each interface is constructed based on the bay correlation.

[0041] The SCD model file of the substation includes all the interval information of the entire station. Various information is cross-coupled, and the impact range between intervals cannot be determined. It is not possible to directly carry out multi-task configuration, debugging, testing and other operations based on intervals. At the same time, during the substation configuration and debugging process, the SCD model file is frequently modified. At this time, it is often necessary to re-debug the entire station after power outage, and re-confirm that all functions are normal before it can be put into operation. This process is time-consuming, high-risk, and engineering construction efficiency is low.

[0042] The primary equipment and its topological relationship, and the primary and secondary equipment association relationship in the SCD model file of the substation are the basis for analyzing the interval association relationship. By analyzing the primary equipment topological relationship, the primary and secondary equipment association, and the interval modeling, on this basis, the relationship information between the equipment, intervals and their configuration contents is mined, the scope of the interval impact is defined, the scope of power outage is reduced, and multi-task parallel automated business mirror debugging based on intervals is carried out, so that multiple intervals can carry out multi-task operations such as configuration, debugging, and testing at the same time, thereby improving debugging efficiency.

[0043] The primary equipment has a good bay division method, but the secondary equipment cannot be completely classified into bays. In view of this situation, the bay division of the SCD model file is carried out according to the structure and function of the substation based on the bay division of the primary equipment, and the bay object is created to achieve a complete classification of the primary and secondary equipment bays. The created bays can include two types of bays: primary equipment bays and functional bays (also called virtual bays).

[0044] Secondary equipment in substations, namely intelligent devices (IEDs), mainly perform metering, control, protection and other functions on primary equipment and serve primary equipment. Some secondary equipment has a strict corresponding matching relationship with primary equipment, while others do not.

[0045] Common primary equipment bays in substations include: bus bay, line bay, bus-coupler bay, transformer bay, switch bay (3 / 2 wiring) and bus equipment bay, etc. For each primary equipment bay, the associated secondary equipment can group the corresponding IED under the bay. Secondary equipment related to the primary (such as measurement and control equipment) belongs to the corresponding primary equipment bay, and is associated with the primary equipment (main equipment or conductive equipment) in the bay through logical nodes, and no functional bay is created.

[0046] The digital debugging of the substation establishes the configuration model of the interval based on the primary equipment. The established interval configuration models mainly include: busbar interval, line interval, bus-tie interval, transformer interval, switch interval (3 / 2 wiring) and busbar equipment interval configuration models. The configuration model of each interval includes the primary equipment of the interval and its topological relationship, and the secondary equipment associated with the primary equipment.

[0047] The SSD (System Specification Description) model in IEC 61850 defines the Bay element, which belongs to the primary device container. The Bay element can describe the bay device, the topological connection relationship, and the relationship between the secondary device and the primary device through the logical node. The SSD model is used in the SCD model as <substation>The content section exists.

[0048] The digital commissioning model builds the bay configuration model based on the SSD model. The typical substation digital commissioning model is modeled by bay, including the configuration models of all bays at each voltage level and the system configuration description SSD model, which constitutes the logical architecture of the bay configuration of the entire station, such as Figure 2 shown.

[0049] In order to better realize the SSD modeling of primary equipment and primary and secondary models, and facilitate the analysis of topological association, the principles of equipment object modeling are further refined and supplemented on the basis of following the IEC 61850 standard: 1. The primary equipment model should include substation model, voltage level model, and primary topology model; 2. The interval should be used as the modeling object, and the interval division and equipment description principles should be clarified; 3. The name of the primary equipment is described in the form of "equipment type code" + "equipment number"; 4. The desc of the primary equipment uses the description of the primary equipment in the monitoring system database; 5. The model file should be able to describe the association between the primary and secondary equipment, and all equipment-related logical nodes LNode should be associated with the corresponding equipment objects. The corresponding relationship between the process layer function pressure plate and the control object (i.e., circuit breaker) should be clarified through the configuration of the logical node LNode. 6. Each primary conductive equipment object should be connected to the ConnectivityNode according to its Terminal, and no primary equipment with unconnected or incomplete connections is allowed; 7. Phase separation equipment and main components should be modeled. 8. The interval should include: lines, busbars, transformers, busbars (sections) and circuit breakers and other live equipment; 9. Virtual equipment, grounding point and phase equipment models can be created according to different main wiring application requirements; 10. The data association between the station control layer and the process layer and the pressure plate control association relationship adopts a short address description scheme.

[0050] Optionally, obtaining the association relationship between intervals across voltage levels in the substation and the association relationship between intervals within the same voltage level based on the digital model information of the substation includes: determining the typical association relationship between different types of intervals in the substation based on the cross-interval association configuration information in the digital model information of the substation; adopting a hierarchical logical decomposition method to hierarchize each interval in the substation according to the voltage level and determine the association relationship between intervals across voltage levels in the substation and the association relationship between intervals within the same voltage level based on the typical association relationship between different types of intervals in the substation.

[0051] Optionally, the cross-interval association configuration information includes five-protection interlocking information, protection device cross-interval association configuration information, and merging unit cross-interval cascading information. Explanatory, combined with actual engineering applications, the cross-interval association configuration information such as five-protection interlocking information, protection device cross-interval association configuration information, and merging unit cross-interval cascading information are sorted out to facilitate the analysis of the association relationship between substation intervals.

[0052] 1. Five-defense interlocking information. The five-defense interlocking rules of the substation are: 1. Prevent the disconnector from pulling and closing with load; 2. Prevent the circuit breaker from being opened and closed by mistake; 3. Prevent the grounding wire from being hung with power; 4. Prevent the switch from being closed with the grounding wire; 5. Prevent the person from entering the energized compartment by mistake. The five-defense interlocking of the substation is divided into the station control layer, the compartment layer and the process layer. The five-defense at the compartment layer works between the measurement and control equipment at the compartment layer. The measurement and control equipment at the compartment layer completes the sending, receiving and logical operation of the interlocking signal, thereby locking or opening the corresponding operation.

[0053] In the SCD model file configuration, the position signals of switches, switches or ground switches required to be sent and received by the five-protection interlocking of the bay layer are expressed through a secondary virtual circuit. The bay layer five-protection model information is configured in the measurement and control device IED device configuration model is the station control access point S1 segment. The S1 segment uses the hierarchical structure of logical device (LDevice) SGOLD->LN0->Inputs->ExtRef to express the signals received from other devices. See Table 1, which shows the association relationship between the position signals of the bay switches, switches or ground switches associated with the five-protection interlocking of a typical bay.

[0054] Table 1 Cross-interval five-protection interlocking relationship matrix

[0055]

[0056]

[0057] 2. Inter-interval association configuration information of protection devices. The inter-interval association configuration information of protection devices mainly includes inter-interval current and voltage collection, failure start-up and reclosing lockout, etc. The model information of the inter-interval association configuration of protection devices is in the GOOSE service access point G1 and SV service access point M1 fragments of the information model process layer of the protection device IED. The virtual terminal expression of the receiving information number in the model with the GOOSE process layer access point LD as "PIGO" and the SV process layer access point LD as "PISV" is the hierarchical structure of LN0->Inputs->ExtRef; the sending signal is expressed in the data set sub-element under the LN0 element with the GOOSE process layer access point LD as "PIGO". See Table 2, which shows the inter-interval association configuration information of the protection device of the interval.

[0059]

[0060] 3. Merging unit cross-interval cascade information. See Table 3, which shows the merging unit cross-interval cascade association configuration information.

[0061] Table 3 Merged unit cross-interval correlation matrix

[0062]

[0063]

[0064] According to the above cross-bay information sorting, see Table 4, the typical correlation relationship between different types of bays in the substation is obtained.

[0065] Table 4 Correlation matrix between different types of intervals

[0066]

[0067]

[0068] The typical correlation between different types of intervals in a substation is the basis for analyzing the correlation between intervals. According to the correlation between intervals in a substation, the clone debugging system uses a hierarchical logical decomposition method to decompose the substation into logical voltage levels, and further decomposes the intervals based on the logical voltage levels. Taking the interval as the unit, based on the typical correlation matrix between different types of intervals in the substation, the correlation between intervals across voltage levels and the correlation between intervals within each logical voltage level are obtained. Based on the correlation between intervals across voltage levels, the correlation between different logical voltage levels can be obtained.

[0069] Explanatory, based on the aforementioned correlation between the intervals across voltage levels in the substation and the correlation between the intervals within the same voltage level, the correlation interface between the different voltage levels and the intervals within the voltage level of the substation is analyzed. That is, the intervals with correlation between different voltage levels are decomposed and marked at the voltage level, and the correlation between different intervals is obtained within the same voltage level. Each interval obtains the intervals associated with the interval and the intervals unrelated to the interval. For example, the interval of the line type obtained by decomposition is only related to the bus interval, bus coupling interval and bus sub-interval, but has no correlation with the reactor interval, station transformer interval and grounding transformer interval. The digital models such as SCD model files, RCD files, one-button sequential control operation tickets, interlocking logic files, database export information files, and monitoring screen sequence files in the substation describe the model information of all intervals in the entire station in units of intervals.

[0070] Based on the associated interfaces of each interval in the substation obtained by analysis, the digital model of the substation is logically decoupled with the associated interfaces of each interval in each substation as the interface unit, and the digital model of the substation is logically decomposed to achieve the decoupling of the association relationship between different voltage levels and different intervals. Logical decoupling means that the original digital model structure is not changed, and the digital model is logically decomposed according to the original structure to obtain the digital model information of the interval and its associated intervals within each voltage level, thereby obtaining multiple interface digital debugging models. There is no correlation between the multiple interface digital debugging models, forming a digital debugging model capable of multi-task collaboration. For example, the decomposed line interface digital debugging model includes the digital models of the line interval and the associated bus interval, bus tie interval and bus equipment interval, and the interface digital debugging models between the line interfaces have no correlation.

[0071] The substation clone debugging model is logically decomposed with the interval-associated interface as the interface unit to obtain the digital debugging clone model of each interface of the substation. Based on this, the cross-voltage level and cross-interval business debugging such as interlocking logic and secondary circuit virtual terminals can be accurately troubleshooted and located. The renovation and expansion debugging can accurately locate the affected scope, improve the accuracy and safety of debugging verification, and avoid inaccurate positioning of the affected scope of debugging verification problems and hidden dangers to debugging operations and power grid operation.

[0072] After logical decoupling, the multi-person collaborative digital debugging clone model of the interface is managed uniformly by name. The name of the digital debugging clone model of the interface includes the station name, voltage level and interval name. The name is organized in the format of station name_voltage level name_interval name, which is unique. The digital debugging clone model data set of the interface is established based on the name. The digital debugging clone model data set of the interface includes the SCD model file, RCD file, one-key sequential control operation ticket, interlocking logic file, data record file, database export information file, monitoring screen sequence file and replacement record file corresponding to the interval information.

[0073] In summary, the main methods for constructing digital debugging clone models of each interface are: 1. Load various types of digital models of the entire station to obtain the interval information under each voltage level; 2. Analyze the correlation information between substation intervals based on the SCD model file; 3. Based on the correlation between substation intervals, take the interval interface as the interface unit, and form the information of the same interface into digital information to construct a data set to represent the logical decoupling information of each interface of the entire station. Logical decoupling forms digital debugging clone models of each interface; 4. There is no correlation between the digital debugging clone models of each interface. Based on multiple digital debugging clone models of each interface, a multi-person collaborative digital debugging model is formed; 5. The names of the digital debugging clone models of the interfaces are uniformly managed, and the names contain the station name, voltage level and interval name, and are unique.

[0074] Explanatory, substation debugging tasks are divided into independent debugging tasks that are independent of each other and full-station debugging tasks that are related to the whole station. Each interface digital debugging clone model corresponds to a debugging task, and multiple interface digital debugging clone models divide independent debugging tasks for multi-person parallel operations. Multi-person collaborative debugging is independent of each other. During debugging, the independent debugging task is subject to authority control. When in the debugging state, the current independent debugging task will be locked, and other personnel cannot carry out debugging, so as to maintain the independence of the independent debugging task.

[0075] After the clone debugging system loads the digital debugging clone model of the interface, it parses the information in the data set of the digital debugging clone model of the debugging interface to obtain the following information: 1. Extract the IP address, MAC address, virtual circuit, MMS, GOOSE and SV configuration information of the SCD model file in the debugging task; 2. Extract the debugging task information in the one-key sequential control ticket, interlocking logic rule file, RCD file, database export information file and monitoring screen sequence file, and analyze the one-key sequential control, anti-mislocking, remote control gateway and monitoring screen point-to-point business debugging elements of the debugging task.

[0076] Based on the configuration information in each independent debugging task, the MMS, GOOSE and SV interaction information of the equipment corresponding to the simulation debugging task is automatically cloned to build a clone simulation environment for digital debugging. Automatically build debugging test cases for each independent debugging task, and build debugging cases for one-button sequential control, anti-mislocking logic, monitoring screen point-to-point and remote control gateway debugging respectively. Then, debug based on the clone simulation environment of digital debugging and the debugging cases of independent debugging tasks. Exemplarily, for one-button sequential control collaborative debugging tasks, the clone verification system selects the operation ticket to enter the debugging state, automatically simulates the device to change the position state of the device once, so that the signal state meets the source state of the operation ticket to be tested, and starts the sequential control operation in the monitoring host. The clone debugging verification system automatically obtains the single-step execution instructions of the sequential control ticket issued by the monitoring host, and performs a closed-loop check with the operation ticket items and operation objects being debugged in the test operation ticket to realize the debugging of the sequential control operation ticket. Anti-error interlocking logic collaborative debugging task, clone verification system imports logic rule test cases, automatically generates forward and reverse logic test library, simulates its five-prevention logic to operate, sends corresponding switch / knife switch position MMS signal to the monitoring host, and operates the monitoring host in turn to determine whether the anti-error interlocking logic is correct when the conditions are met and when the conditions are not met, to achieve the forward and reverse logic verification of the anti-error interlocking logic. Monitoring screen point-to-point collaborative debugging task, clone verification system simulates triggering simulation measurement and control device signal changes, and then obtains the received trigger result signal sequence from the monitoring host, and compares the trigger sequence with the actual received trigger sequence value through a closed loop to achieve monitoring host communication debugging and screen-to-point debugging. The debugging results form a debugging report, which supports pdf, word and csv formats, and supports debugging report import and export. Telecontrol gateway debugging task, clone verification system simulates triggering simulation interval layer device signal changes, receives telecontrol device 104 signal, and compares the trigger value with the actual received 104 signal through a closed loop to achieve telecontrol gateway debugging verification.

[0077] In a possible implementation, when the independent debugging tasks corresponding to the digital debugging clone models of each interface of the substation are executed in parallel through the digital debugging clone models of each interface, there is only one execution process of the same independent debugging task at the same time.

[0078] Explanatory, multi-task collaborative independent debugging task sets multiple states: not debugged, debugging, and debugging completed. When the independent debugging task has not started debugging, it is set to the not debugged state; when the independent debugging task is being debugged, it is set to the debugging state; when the independent debugging task is completed, it is set to the debugging completed state. The authority of the independent debugging task in debugging is locked, and the authority is unlocked when the debugging is exited midway or the debugging is completed. After the independent debugging task is debugged, its task state is set to the debugging completed state.

[0079] In a possible implementation, before merging the digital debugging clone models of each interface that has completed the independent debugging task, it also includes: verifying the digital signature information in the digital debugging clone models of each interface that has completed the independent debugging task, and re-executing the corresponding independent debugging task on the digital debugging clone models of the interface that have failed the digital signature information verification.

[0080] Explanatory, digital signature is performed on each interface digital intelligent debugging clone model, and the digital signature information is saved in the digital model data set of the interface digital intelligent debugging clone model. After completing all independent debugging tasks in the station, the debugging of the whole station debugging task with the whole station associated tasks is carried out. The debugging of the whole station debugging task adopts an independent method, and there is no need for collaborative debugging.

[0081] Load and extract the digital debugging clone models of each interface of the entire station, extract the digital signature information of each interface digital debugging clone model, and perform data signature information consistency verification. The digital debugging clone models of the interfaces that fail the digital signature information verification are returned, and a prompt is given that they are unqualified, and re-debugging verification is performed. The digital debugging clone models of the interfaces that pass the digital signature information verification are merged to form the digital debugging clone model of the entire station to debug the debugging tasks of the entire station.

[0082] When debugging the whole station debugging task, the clone debugging verification system loads the whole station digital debugging clone model, simulates the whole station's measurement and control devices and protection equipment based on the SCD model file in the whole station digital debugging clone model, and builds a complete simulation environment for the whole station. Then extract the debugging task information related to different voltage levels and different intervals in the one-key sequential control ticket, interlocking logic rule file, RCD file, database export information file, and monitoring screen sequence file, and build a one-key sequential control, anti-mislocking, telecontrol gateway, and monitoring screen point-to-point automatic debugging verification case for the whole station debugging task.

[0083] Based on the complete simulation environment of the whole station and the one-button sequential control, anti-error interlocking, telecontrol gateway and monitoring screen point-to-point automatic debugging verification cases of the whole station debugging task, the one-button sequential control, anti-error interlocking, telecontrol gateway and monitoring screen point-to-point debugging of the whole station debugging task are debugged. After completing the debugging of the whole station debugging task, a digital debugging clone model of the whole station is formed after test verification. After the verification is correct, the digital debugging clone model of the whole station is losslessly migrated from the clone debugging system to the actual operating substation system and equipment, realizing the debugging verification test without power outage on site, greatly improving work efficiency and reducing the power outage time on site.

[0084] In a possible implementation manner, taking one-key sequential control service debugging verification as an example, the main process of the digital debugging method for substation automation service of the present invention is explained.

[0085] The sequence control ticket file configured by the substation monitoring system follows a unified format. The definition of sequence control ticket file types includes equipment state file and operation ticket file. The two files are used in groups. The equipment state file describes the equipment state information of one-key sequence control. The equipment state of the entire station is exported as a text file. The file name format is: substation name-equipment state-YYYYMMDD-hhmmss.txt, for example: 500kV Zhuji substation-equipment state-20220310-104744.txt. The content of the equipment state description includes the interval name, version information and equipment state information. The equipment state information includes the number of equipment states in this interval, the equipment state description, and the logical definition of each equipment state. The equipment state file adopts a hierarchical structure. The operation ticket file describes the equipment operation information of one-key sequence control. The operation ticket of the entire station is exported as a text file. The file name format is: substation name-operation ticket-YYYYMMDD-hhmmss.txt, for example: East China_Zhuji substation-operation ticket-20220322-181216.txt. The operation ticket file describes the one-key sequential control operation ticket configuration information. The file content includes the substation, voltage level, bay name, number of operation tasks, definition of each operation task and blocking signal information. The operation ticket file adopts a hierarchical description.

[0086] The process of collaborative parallel operation debugging verification of one-key sequential control business debugging is as follows: 1. Build a clone debugging system; 2. Import digital business models; 3. Analyze the correlation between different voltage levels and different intervals in the station; 4. Build a digital debugging clone model of the one-key sequential control interface for multi-task collaboration; 5. Establish independent one-key sequential control independent debugging tasks; 6. Build a debugging verification environment for each independent debugging task; 7. Carry out automatic debugging verification of individual one-key sequential control independent debugging tasks, and obtain the digital debugging clone model of the one-key sequential control interface for each independent debugging task; 8. Merge the digital debugging clone model of the one-key sequential control interface for independent independent debugging tasks; 9. Import the merged digital debugging clone model of the one-key sequential control full station; 10. Carry out debugging of the one-key sequential control full station debugging task for the whole station; 11. Migrate the digital debugging clone model of the one-key sequential control full station for the one-key sequential control full station debugging task to the on-site system and equipment without loss; 12. Complete the one-key sequential control business debugging.

[0087] The digital debugging method for substation automation services of the present invention constructs a clone debugging system, imports a digital debugging model, analyzes the association relationship between the intervals in the station based on the SCD model file, and constructs digital debugging clone models of each interface of the substation based on the SCD model file of the substation, one-key sequential control ticket, anti-mislocking and other cross-interval association configuration information according to the analyzed relationship. Based on the digital debugging clone model of each interface, multi-person collaborative mirror debugging is started, and finally the business after multi-person collaborative debugging is integrated into the business of the entire station and imported into the on-site system to achieve the effect of no power outage or less power outage.

[0088] The present invention constructs a clone debugging system, analyzes the correlation between intervals across voltage levels in the substation and the correlation between intervals within the same voltage level, constructs independent interface digital debugging clone models, and establishes a multi-person collaborative debugging digital model. On this basis, multi-person collaborative debugging is realized to complete the substation automation business debugging. Firstly, the problem of low efficiency of debugging mode of single task can be solved based on parallel operation. The debugging of automation business of a station generally takes more than 30 days, and the operation cycle is long. Through the present invention, it can be carried out in the manner of debugging by different manufacturers alone, debugging by multi-person collaborative division of labor, etc., and the debugging of automation business of a station is shortened to less than 7 days, and the work efficiency is improved by more than 4 times; secondly, by constructing a clone debugging system to decouple the debugging verification environment from the on-site physical environment, it can solve the problems of on-site power outage debugging grid operation, complex on-site work, high operation risk, complex operation and safety measures of the operating system, many on-site construction surfaces, cross-operation of construction personnel, etc., avoid the on-site power outage operation affecting the operation of the grid, eliminate the on-site debugging equipment and personal risks, and reduce the management cost of the project; furthermore, the correlation relationship between the intervals across voltage levels in the substation and the correlation relationship between the intervals within the same voltage level are obtained, and the debugging of cross-voltage levels and cross-interval business such as interlocking logic and secondary circuit virtual terminals can accurately check and locate problems, and the scope of influence can be accurately located in the expansion and reconstruction debugging, so as to improve the accuracy and safety of debugging verification, avoid inaccurate positioning of the scope of influence of debugging verification problems and bring hidden dangers to debugging operations and power grid operation.

[0089] Through the method of the present invention, debugging and verification can be carried out independently according to different manufacturers, and debugging and verification can be carried out according to multi-person collaborative parallel operations. The problems of debugging and verification can be accurately checked and located. The affected scope of renovation and expansion debugging can be quickly located. For new stations, local debugging, local configuration and local testing can be carried out. It is not necessary to complete all configurations before debugging and testing. The debugging environment is decoupled from the on-site physical environment, thereby improving the debugging efficiency of substation automation services, avoiding on-site power outages that affect power grid operation, and providing protection for the safe and stable operation of the power grid.
