Description

Technical Field

[0001] This invention belongs to the field of power system automatic control technology, and relates to the sequential control technology of substation systems. Specifically, it relates to a method and system for generating and applying a one-click sequential control expert test library for simulation testing. Background Technology

[0002] Currently, the State Grid Corporation of China is widely promoting and applying "one-click sequential control" technology in various substations. "One-click sequential control" is an operation mode characterized by pre-configured software for operation items, modular operation tasks, automatic equipment status identification, intelligent verification of anti-maloperation interlocks, one-click initiation of operation steps, automatic sequential execution of the operation process, and automatic judgment of operation results. Applying one-click sequential control technology can achieve one-click automatic execution of multiple primary equipment operations, reducing the problems of low efficiency, high error rates, and high manpower requirements associated with manual switch operation.

[0003] The deployment and practical application of one-click sequential control cannot be separated from detailed testing and verification of the sequential control logic. However, the actual field testing and verification are limited by the operating conditions of the primary equipment and the strict judgment criteria required by the operation itself, which makes it impossible to complete the testing and verification work efficiently and with high quality.

[0004] Testing one-click sequential control through simulation can effectively address the problems of low efficiency, error susceptibility, and high manpower requirements encountered in actual testing. However, existing simulation testing technologies lack independent modeling of the one-click sequential control device state configuration library and operation ticket configuration library. Therefore, while testing one-click sequential control through simulation is theoretically feasible, it lacks practicality in actual operation. Although some existing technical literature considers generating test benchmark libraries, these libraries lack universality and can only be generated directly from actual engineering SCD files, making widespread application difficult. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a method for generating and applying a one-click sequential control expert test library for simulation testing. By constructing a general test library, simulation testing can be effectively carried out, and a verified test library can be formed through self-evaluation, thereby achieving the correctness assessment of the test library itself.

[0006] The present invention adopts the following technical solution.

[0007] A method for generating and applying a one-click sequential control expert test library for simulation testing includes the following steps:

[0008] Step 1: Determine if there is an expert test library. If there is no expert test library, further classify the typical voltage level, wiring method, and bay type of the power grid and proceed to Step 2. If there is an expert test library, proceed to Step 7.

[0009] Step 2: Build an intermediate database based on the standard operation ticket file, and use the information points in the intermediate database to describe the configuration of the device status and operation ticket definition for the typical interval operation ticket of one-click sequential control.

[0010] Step 3: Construct a dictionary and interpret the information points in the intermediate database. The dictionary is a semantic mapping relationship library formed by interpreting each information point defined in the intermediate database.

[0011] Step 4: Using the information points in the intermediate database, construct a one-click sequential control expert test library based on the standard one-click sequential control operation ticket and the bay type under typical wiring methods. The expert test library includes the equipment status test library and the operation ticket test library.

[0012] Step 5: Classify the constructed expert test library according to typical voltage levels, wiring methods, and bay types to form different types of expert test library sets;

[0013] Step 6: Perform simulation tests or verification tests on the generated expert test library set to obtain a verified expert test library set;

[0014] Step 7: Perform simulation tests or verification tests on the expert test library to obtain a set of verified expert test libraries;

[0015] Step 8: Apply the expert test library in the verified expert test library set as the correctly configured test library directly to one-click sequential control simulation tests in other similar scenarios.

[0016] Preferably, in step 1, typical voltage levels include 750kV, 500kV, 330kV, 220kV, 110kV, 66kV, 35kV, 10kV, and 0.4kV.

[0017] Typical wiring methods include 3 / 2 wiring, double bus wiring, double bus double branch wiring, double bus single branch wiring, single bus wiring, single bus segmented wiring, single bus double segmented wiring, single bus three segmented wiring, internal bridge wiring, external bridge wiring, and expanded internal bridge wiring.

[0018] Typical bay types include busbar, main transformer, line, bus tie, bus branch, capacitor, reactor, and station service transformer bay types.

[0019] Preferably, in step 2:

[0020] The intermediate database is constructed based on the information points in the standard operating tickets for each main wiring method. By analyzing the definition of information points in the standard operating tickets for each voltage level, main wiring method, and bay type, the corresponding intermediate database is constructed. The intermediate database includes all the information point configurations required for one-click sequential control configuration.

[0021] The information points in the constructed intermediate database include main position signals, auxiliary position signals, primary and secondary equipment monitoring self-test signals, secondary circuit monitoring signals, analog signals, remote control signals, etc. Using the information points in the intermediate database, the configuration description of the equipment status and operation ticket definition of one-click sequential control typical interval operation ticket can be realized.

[0022] Preferably, step 3, constructing the dictionary database, further includes:

[0023] The dictionary is a semantic mapping database formed by interpreting each information point defined in the intermediate database. The dictionary is constructed by using a keyword information combination weighting algorithm to determine the interpretation algorithm for each information point in the intermediate database.

[0024] Preferably, in step 3, the dictionary definition includes mapping the signal configuration in the actual engineering SCD file to the information point configuration in the intermediate database. The definition object is the information point in the intermediate database, and the definition entry is the corresponding signal description or reference key information combination obtained from the specific engineering SCD file. The similarity between the target entry and the definition object is determined by a weighted algorithm. The target entry with the highest similarity is the dictionary definition of the definition object, and the two can form an associated mapping relationship.

[0025] Preferably, step 4 further includes:

[0026] Step 4-1: Referring to the standards for classifying the voltage level, wiring method, and bay type of the substation in Step 1, construct a specific intermediate database modeling object, which serves as the basic unit of the expert test library.

[0027] Step 4-2: Define device states for the basic units of the expert test library and generate the device state test library;

[0028] Step 4-3: Define operation tickets for each pair of device states in the device state test library that have operation tickets, and obtain the operation ticket test library;

[0029] Step 4-4: Sequentially complete the operation process definition for specific voltage levels, wiring methods, and bay types, forming a configuration group consisting of several operation processes. This configuration group is the expert test library that describes the operation ticket configuration for the corresponding bay.

[0030] Preferably, step 5 further includes:

[0031] The expert test library generated in step 4 is divided according to voltage level, wiring method, and bay type to form an expert test library set. This expert test library set can be continuously expanded and supplemented according to special needs and actual field conditions. That is, when a new expert test library that does not meet the existing voltage level, wiring method, and bay type appears, it is added to the expert test library set. Under dynamic expansion conditions, test libraries suitable for various standard and non-standard configurations in the field are formed, and standard and non-standard expert test libraries are formed. For the same voltage level, wiring method, and bay type, there is one standard expert test library and several non-standard expert test libraries.

[0032] Preferably, in step 6, if the expert test library set is directly used for simulation testing, then step 6 further includes:

[0033] Step 6-1: Import the SCD file and select the corresponding expert test library. The expert test library information configuration is completed through the constructed dictionary library, and the automatic mapping and association with the signals in the SCD file are completed to form an instantiated expert test library.

[0034] Step 6-2: Using MMS simulation, the actual one-click sequential control system is configured and verified using an instantiated expert test library to determine whether the one-click sequential control system configuration is correct.

[0035] Step 6-3: Based on the results of the configuration verification test, generate the status test report and operation ticket test report for each interval device of the one-click sequential control system under test;

[0036] Step 6-4 verifies and corrects the correctness of the expert test library configuration through manual verification and judgment in the first test, and marks the expert test library that has completed the first test verification and correction as a verified expert test library, forming a set of verified expert test libraries.

[0037] Preferably, step 6-1 further includes:

[0038] Step 6-1-1: By constructing a dictionary to interpret the information point configuration in the intermediate information database, the dictionary defines a signal description or a combination of reference key information for each signal point in the intermediate information database.

[0039] Step 6-1-2: Assign weights to each sub-element in the key information combination. The standard for assigning weights is the characteristics of the information object that the sub-element can represent.

[0040] Step 6-1-3: Import the SCD file and obtain the similarity value between the information points in the SCD file and the target information points in the intermediate information database through weighted calculation;

[0041] Step 6-1-4: Associate and map the information points with the highest similarity to the target information points in the intermediate information database to realize the instantiation of the expert test database.

[0042] Preferably, in step 6-2:

[0043] Configuration verification testing includes testing the one-click sequential control interval device state configuration and interval operation ticket configuration. The testing process should include positive logic testing and negative logic testing; among them,

[0044] Device state simulation testing involves the testing device simulating device state signals based on an expert test library for the divided interval types, verifying the correctness of the one-click sequential control device state logic configuration;

[0045] Operation ticket simulation testing involves the testing device performing operation ticket tests on selected intervals based on an expert test library to verify the correctness of all operation ticket configurations.

[0046] Preferably, in step 6-3:

[0047] The device state test report is a test report generated based on the device state configuration information of the one-click sequential control expert test library in step 4 and the evaluation of the device state test results in step 6-2. Its content includes the configuration information of each device state in each interval, that is, the signal state combination contained in each device state, and the corresponding evaluation of the test results of each device state.

[0048] The operation ticket test report is a test report generated based on the operation ticket configuration information of the one-click sequential control expert test library in step 4 and the evaluation of the operation ticket test results in step 6-2. Its content includes configuration information such as the operation process, execution conditions and confirmation conditions of each operation ticket, as well as the evaluation of the corresponding operation ticket test results.

[0049] Preferably, step 7 further includes:

[0050] If an expert test library already exists, it can be verified first. The expert test libraries that are evaluated correctly are marked as verified, thus forming a set of verified expert test libraries.

[0051] Alternatively, the existing expert test library can be directly applied to the engineering one-click sequential control simulation test for the first time. The correctness of the expert test library can be determined by manual evaluation. The expert test library that is confirmed to be correct is marked as verified, thus forming a set of verified expert test libraries.

[0052] A terminal includes a processor and a storage medium, the storage medium being used to store instructions;

[0053] The processor is used to operate according to the instructions to execute the steps of the one-click sequential control expert test library generation and application method for simulation testing.

[0054] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of a method for generating and applying a one-click sequential control expert test library for simulation testing.

[0055] The beneficial effects of this invention are as follows: Compared with the prior art, the method for generating and applying a one-click sequential control expert test library for simulation testing proposed in this invention can effectively address the problem of simulation testing by constructing a general test library for one-click sequential control simulation testing. Simultaneously, it solves the problem of correctness assessment of the test library itself by forming a verified test library through self-evaluation, enabling the effective application and implementation of one-click sequential control simulation testing and making it applicable to various scenarios. This invention includes at least the following beneficial effects:

[0056] 1. The generation method proposed in this invention can construct an intermediate database based on the signal definition in the standard one-click sequential control operation ticket, construct a dictionary to interpret the information points in the intermediate database, and realize the mapping instantiation of signal points in the intermediate database with signals in the actual engineering SCD file;

[0057] 2. Based on the standard one-click sequential control operation ticket and the bay type under typical wiring method, this invention uses information points in the intermediate database to construct a one-click sequential control expert test library, including a device state test library and an operation ticket test library. The expert test library is instantiated by importing SCD files and using a dictionary library. Combined with MMS simulation technology, the expert test library is applied to one-click sequential control simulation testing in specific projects.

[0058] 3. This invention evaluates the expert test library by combining the results of the first simulation test, determines whether the expert test library itself is correct, and marks the expert test library that is evaluated correctly as a verified expert test library, thereby realizing the evaluation of the correctness of the test library itself.

[0060] Figure 2 This is a schematic diagram of the intermediate database configuration for the expert test library proposed in this invention;

[0061] Figure 3 This is a flowchart illustrating the method for generating a one-click sequential control expert test library for simulation testing proposed in this invention. Detailed Implementation

[0062] The present application will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and should not be construed as limiting the scope of protection of the present application.

[0063] One-click sequential control technology is an operation mode for substation switching operations. It enables modular construction of operation tasks, one-click initiation of operation steps, and automatic sequential execution of the operation process, thereby improving operational efficiency, reducing operational risks, and enhancing emergency response capabilities. In practical applications, the deployment and application of one-click sequential control require detailed testing and verification of the sequential control logic. However, the actual field testing and verification of the sequential control logic is limited by the operating conditions of the primary equipment and the strict judgment criteria required by the operation itself, making it difficult to complete the testing and verification work efficiently and with high quality.

[0064] Testing one-click sequential control through simulation testing can effectively solve the problems of low efficiency, easy error and high manpower input faced by actual testing. However, conventional simulation testing methods do not independently model the one-click sequential control device state configuration library and operation ticket configuration library. Therefore, the simulation testing process is currently feasible in principle, but not practical in actual operation.

[0065] like Figure 1 As shown, to solve the above problems, this invention proposes a method for generating and applying a one-click sequential control expert test library for simulation testing. This method specifically includes the following steps:

[0066] Step 1: Determine if there is an expert test library. If there is no expert test library, further classify the typical voltage level, wiring method, and bay type of the power grid and proceed to Step 2. If there is an expert test library, proceed to Step 7.

[0067] The typical voltage levels of the power grid include 750kV, 500kV, 330kV, 220kV, 110kV, 66kV, 35kV, 10kV, and 0.4kV. Typical wiring methods include 3 / 2 wiring, double busbar wiring, double busbar double branch wiring, double busbar single branch wiring, single busbar wiring, single busbar segmented wiring, single busbar double segmented wiring, single busbar three segmented wiring, internal bridge wiring, external bridge wiring, and expanded internal bridge wiring. Typical bay types include busbar, main transformer, line, bus tie, bus branch, capacitor, reactor, and station service transformer bay types.

[0068] Step 2: Build an intermediate database based on the standard operation ticket file, and use the information points in the intermediate database to describe the configuration of the device status and operation ticket definition for the typical interval operation ticket of one-click sequential control.

[0069] In this embodiment, the standard operation ticket is a one-click sequential control operation ticket that conforms to the unified technical specifications for one-click sequential control transformation or a fixed standard for a specific region. The technical specifications and standards of the standard operation ticket are issued by the State Grid or the regional power grid, and the equipment status conditions, operating conditions and other signals in the standard operation ticket have been standardized.

[0070] The intermediate database is constructed based on the information points in the standard operating tickets for each main wiring method. By analyzing the definition of information points in the standard operating tickets for each voltage level, main wiring method, and bay type, the corresponding intermediate database is constructed. The intermediate database includes all the information point configurations required for one-click sequential control configuration.

[0071] The information points in the constructed intermediate database include main position signals, auxiliary position signals, primary and secondary equipment monitoring self-test signals, secondary circuit monitoring signals, analog signals, and remote control signals. Using the information points in the intermediate database, the configuration description of the equipment status and operation ticket definition for one-click sequential control of typical interval operation tickets can be realized.

[0072] Specifically, refer to Figure 2 The diagram illustrates the process of dividing the substation into typical voltage levels, wiring methods, and bay types as described in step 1. This forms a specific intermediate database modeling object. Then, intermediate database information points are established under the modeling object, including at least the main position signal, auxiliary position signal, primary and secondary equipment monitoring self-test signal, secondary circuit monitoring signal, analog signal, and remote control signal information points.

[0073] For example, for a substation bay with a voltage level of 500kV, a double busbar connection, and a bus tie bay type, specific signal points such as circuit breaker position, 1G disconnector position, and 2G disconnector position are defined according to the signal definitions in the standard operation ticket document. These signal points also include main position signals, auxiliary position signals, primary and secondary equipment monitoring self-test signals, secondary circuit monitoring signals, analog signals, and remote control signals.

[0074] Step 3: Construct a dictionary database, which is a semantic mapping relationship database formed by interpreting each information point defined in the intermediate database.

[0075] The construction of the dictionary database includes interpreting the information points in the intermediate database and mapping the signal configurations in the actual engineering SCD file to the information point configurations in the intermediate database to form a semantic association mapping.

[0076] Specifically, the construction of the dictionary includes interpreting information points in the intermediate database and mapping the signal configurations in the actual engineering SCD file to the information point configurations in the intermediate database. The interpretation objects are the information points in the intermediate database, and the interpretation entries are combinations of corresponding signal descriptions or reference key information obtained from the specific engineering SCD file. The similarity between the target entry and the interpretation object is determined by a weighted algorithm. The target entry with the highest similarity is the dictionary definition of the interpretation object. The two can form a semantic association mapping relationship, thereby obtaining the dictionary.

[0077] Determining the similarity between key information combinations and information points in the intermediate database using a weighted algorithm also includes: assigning weights to each keyword in the key information combination, with the weighting standard being the characteristics of the information object that the keyword can represent; importing the specific project SCD file; and obtaining the similarity value between the information points in the SCD file and the information points in the intermediate database through weighted calculation. The similarity value calculation formula is as follows:

[0078]

[0079] Where m is the keyword index, m w This represents the weight of keyword m, where M is the total number of keywords and n is the similarity value.

[0080] The target entry with the highest similarity is the dictionary definition of the object being defined. The two form a semantic association mapping relationship. By defining each information point defined in the intermediate database, the dictionary is obtained.

[0081] Step 4: Using the information points in the intermediate database, construct a one-click sequential control expert test library based on the standard one-click sequential control operation ticket and the bay type under typical wiring methods. The expert test library includes the equipment status test library and the operation ticket test library.

[0082] Specifically, the information points defined in the intermediate information library are used for configuration to generate a one-click sequential control general expert test library with specific voltage levels, wiring methods, and interval types. The configuration content of this expert test library includes device state configuration and operation ticket configuration. The device state configuration includes device state division and signal status definition for each device state. The operation ticket configuration includes the initial state and target state definition for each operation ticket, the operation steps for each operation ticket, and the pre-execution conditions and confirmation conditions for each operation step.

[0083] Step 4 also includes:

[0084] Step 4-1: Based on the voltage level, wiring method, and bay type standards of the substation as defined in Step 1, construct a specific intermediate database modeling object, which serves as the basic unit of the expert test library.

[0085] Step 4-2: Define device states for the basic units of the expert test library and generate the device state test library;

[0086] Several device states are defined for the basic unit of the expert test library. Each device state contains a combination of specific signal point states in the intermediate database, and finally, a device state test library for the voltage level, wiring method, and interval type object is generated.

[0087] Specifically, for objects with different voltage levels, wiring methods, and bay types, three types of equipment states are defined: operating, hot standby, and cold standby. Therefore, the number of equipment states varies depending on the object, but at least three equipment states are included. If the wiring method involves complex wiring situations such as double bus wiring, the operating and hot standby states may cross bus lines, meaning there may be multiple bus operating and hot standby states.

[0088] For example, the 220kV double busbar bay object is defined with five equipment states: running (#1 busbar), running (#2 busbar), hot standby (#1 busbar), hot standby (#2 busbar), and cold standby.

[0089] Based on the expert principles of the standard operating procedure, signal points in the intermediate database are added to the defined equipment states, and the value of each signal point is defined. The remote signaling signals are defined to be open or closed, and the telemetry signals are defined to be defined to be numerically required, forming a configuration group consisting of several signal state conditions. This configuration group is the expert test library that describes the equipment state configuration of the corresponding interval.

[0090] Step 4-3: Define operation tickets for each pair of device states in the device state test library that have operation tickets, and obtain the operation ticket test library;

[0091] For each pair of device states defined in the above objects, there is an operation ticket definition operation ticket. Select the initial state and target state in the device state respectively to generate an operation ticket. Each operation ticket contains a specific remote control operation combination in the intermediate database, and finally obtains the operation ticket test library for the voltage level, wiring method and interval type object.

[0092] Taking a 220kV double busbar bay as an example, the following operations need to be defined: Operation (#1 busbar) to Operation (#2 busbar), Operation (#1 busbar) to Hot Standby (#1 busbar), Operation (#1 busbar) to Cold Standby, Operation (#2 busbar) to Operation (#1 busbar), Operation (#2 busbar) to Hot Standby (#2 busbar), Operation (#2 busbar) to Cold Standby, Hot Standby (#1 busbar) to Operation (#1 busbar), Hot Standby (#1 busbar) to Cold Standby, Hot Standby (#2 busbar) to Operation (#2 busbar), Hot Standby (#2 busbar) to Cold Standby, Cold Standby to Operation (#1 busbar), Cold Standby to Hot Standby (#1 busbar), Cold Standby to Operation (#2 busbar), Cold Standby to Hot Standby (#2 busbar), Cold Standby to Hot Standby (#2 busbar), generating a total of 14 typical operation tickets.

[0093] Each generated operation ticket includes several operation steps, and each operation step includes pre-operation conditions and post-operation confirmation conditions. For example, to switch from cold standby to operation (#1 bus), the 1G disconnector (#1 bus disconnector), the 6G disconnector (line-side disconnector), and the circuit breaker must be closed sequentially. The pre-operation conditions for switching on the 1G disconnector are that the main signal and auxiliary signal of the 1G disconnector are both in the open position. The post-operation confirmation conditions are that the main signal and auxiliary signal of the 1G disconnector are both in the closed position.

[0094] Step 4-4: Sequentially complete the operation process definition for specific voltage levels, wiring methods, and bay types, forming a configuration group consisting of several operation processes. This configuration group is the expert test library that describes the operation ticket configuration for the corresponding bay.

[0095] Specifically, the expert test library generated through the above configuration is a non-instantiated general test library. After instantiation, it can be applied to simulation tests of one-click sequential control configuration of any object of the same voltage level, wiring method, and interval type.

[0096] Step 5: Classify the constructed expert test library according to voltage level, wiring method and bay type to form different types of expert test library sets;

[0097] The expert test library collection includes a typical one-click sequential control configuration library for various voltage levels, wiring methods, and bay types, generated based on intermediate database configurations. It can be continuously expanded and supplemented according to needs and actual field conditions, forming a test library suitable for various standard and non-standard configurations in the field under dynamic expansion conditions.

[0098] Specifically, step 5 also includes:

[0099] The expert test library generated in step 4 is categorized according to different voltage levels, wiring methods, and bay types to form an expert test library set. The classification of voltage levels, wiring methods, and bay types can refer to the classification standards of typical voltage levels, wiring methods, and bay types in step 1. This expert test library set can be continuously expanded and supplemented based on special needs and actual field conditions. That is, when a new expert test library that does not meet the existing voltage level, wiring method, and bay type appears, it is added to the expert test library set. Under dynamic expansion conditions, test libraries suitable for various standard and non-standard configurations in the field are formed, and standard and non-standard expert test libraries are formed. The relationship is generally that for the same voltage level, wiring method, and bay type, there is one standard expert test library and several non-standard expert test libraries. Finally, through iterative accumulation, a one-click sequential control test that can be used for most voltage levels, wiring methods, and bay types is formed.

[0100] A preferred implementation is to save the standard expert test library as a general test library, which can be used for one-click sequential control testing of most common standard configuration sites, and save the non-standard expert test library as a special test library and mark its specificity, which can be used for one-click sequential control testing of a few special sites.

[0101] Step 6: Perform simulation tests or verification tests on the generated expert test library set to obtain a verified expert test library set, and then proceed to step 8;

[0102] Specifically, methods for testing expert test database sets include:

[0103] The expert test library set is directly used for one-click sequential control simulation test: Import the SCD file and select the corresponding expert test library. The expert test library information configuration is automatically mapped and associated with the signals in the SCD file through the constructed dictionary library to form an instantiated expert test library. Then, through the MMS simulation function, the simulation test of the one-click sequential control device status and operation ticket is carried out with the help of the instantiated expert test library. The correctness of the test results is verified by manual review. When there is an inconsistency between the engineering configuration and the expert test library, it is necessary to check and evaluate whether they are correct. After correction, the simulation test is continued until all evaluations are correct. The expert test library that has completed the first test verification will be marked as verified and a verified expert test library set will be formed.

[0104] Alternatively, the expert test library set can be independently verified: design test scenarios to verify the expert test library, determine the correctness of the expert test library through manual evaluation, mark the expert test library that is correctly evaluated as verified, and form a set of verified expert test libraries.

[0105] Furthermore, if the expert test library set is used directly for simulation testing, then step 6 also includes:

[0106] Step 6-1: Import the SCD file and select the corresponding expert test library. The expert test library information configuration is completed through the constructed dictionary library, and the automatic mapping and association with the signals in the SCD file are completed to form an instantiated expert test library.

[0107] Step 6-1-1: The dictionary library defines the information point configuration in the intermediate information library by interpreting the constructed dictionary library. The dictionary library defines the signal description or reference key information combination for each signal point in the intermediate information library.

[0108] For example, for the 220kV double busbar connection bus tie interval circuit breaker position signal defined in the intermediate information database, the signal description keywords are: 1: circuit breaker, 2: switch, 3: position, 4: bus tie monitoring and control, and 5: 220kV.

[0109] Step 6-1-2: Assign weights to each sub-element in the key information combination. The standard for assigning weights is the characteristics of the information object that the sub-element can represent.

[0110] Based on the example of the 220kV double busbar connection bus tie interval circuit breaker position signal in step 6-1-1, the keyword weights are assigned as follows: Keyword 1 has a weight of 1, Keyword 2 has a weight of 1, Keyword 3 has a weight of 0.5, Keyword 4 has a weight of 1, and Keyword 5 has a weight of 1. In the example, keywords 1, 2, 4, and 5 can all reflect the important characteristics of the information object, while keyword 3 is a general description, so keyword 3 has a lighter weight when assigning weights.

[0111] Step 6-1-3: Import the SCD file and obtain the similarity value between the information points in the SCD file and the target information points in the intermediate information database through weighted calculation;

[0112] Specifically, the signals in the imported SCD file are traversed, and the similarity value is calculated using a weighted average. The calculation formula is as follows:

[0113]

[0114] Where m is the keyword index, m w This represents the weight of keyword m, where M is the total number of keywords and n is the similarity value.

[0115] Step 6-1-4: Associate and map the information points with the highest similarity to the target information points in the intermediate information database to realize the instantiation of the expert test database.

[0116] The information point with the highest similarity value is associated and mapped to the signal defined in the intermediate information library. For example, combined with step 5-1, it is mapped to the position signal of the 220kV double bus tie interval circuit breaker, thus realizing the instantiation of the signal.

[0117] Step 6-2: Using MMS simulation, the actual one-click sequential control system is configured and verified using an instantiated expert test library to determine whether the one-click sequential control system configuration is correct.

[0118] After instantiation, the expert test uses the MMS simulation function and the instantiated expert test library to perform one-click sequential control of device status and operation tickets. The correctness of the test results is verified manually. When there is an inconsistency between the engineering configuration and the expert test library, the two need to be checked and evaluated for correctness. After correction, the simulation test is continued until all evaluations are correct.

[0119] Specifically, the instantiated expert test library undergoes verification testing. Specifically, when first applied to a real-world engineering one-click sequential control simulation test or when a simulation test specifically designed to verify the expert test library logic is built, the correctness of the expert test library's configuration is determined through manual evaluation. The standard for manual evaluation is the configuration logic described in the standard operation ticket. The expert test library should be consistent with the configuration logic described in the standard operation ticket. The evaluation process includes evaluation of the device-state test library and evaluation of the operation ticket test library. The specific methods are as follows:

[0120] The configuration verification test includes testing the one-click sequential control interval device state configuration and interval operation ticket configuration. The test process should include positive logic testing and negative logic testing.

[0121] Device state simulation testing involves a testing device simulating device state signals based on an expert test library for defined interval types, verifying the correctness of the one-click sequential control device state logic configuration. Specifically, device state simulation testing also includes the following steps:

[0122] First, the simulation service simulates the state of all signal combinations in the device state with a single click, ensuring that the selected interval device state meets the positive logic test requirements. It then checks whether the corresponding interval device state in the one-click sequential control host meets the conditions. If the conditions are met, the reverse logic test is performed on the configuration logic of the device state individually. That is, if the state of a single signal in each signal combination of the corresponding device state is not met, the corresponding interval device state in the one-click sequential control host is checked to confirm whether the changed signal caused the change in the sequential control device state. This process continues until all signals of the selected interval device state are tested, verifying the correctness of all device state configurations and achieving device state simulation testing based on an expert test library.

[0123] Operation ticket simulation testing involves the testing device performing operation ticket tests on selected intervals based on an expert test library to verify the correctness of all operation ticket configurations. Specifically, the operation ticket simulation test also includes the following steps:

[0124] First, the simulation ensures all signals meet the selected interval device state. Then, the test device retrieves the operation ticket test task, setting all logical conditions within the test task to be satisfied. The corresponding operation task is retrieved from the one-key sequential control host and execution begins. The test device returns all satisfied conditions according to the operation ticket flow definition and pre-execution and confirmation conditions in the expert test library. After completing the positive logic test with all logical conditions satisfied, reverse logic tests are performed by sequentially assigning individual pre-execution conditions or post-execution confirmation conditions that are not satisfied. This process continues until all operation tickets for the selected interval are tested, verifying the correctness of all operation ticket configurations and realizing device state simulation testing based on the expert test library.

[0125] After completing the equipment state simulation test and the operation ticket simulation test, the expert test library will be marked as verified. In the subsequent one-click sequential control simulation test, any engineering configuration that differs from the verified expert test library will be identified as an incorrect configuration.

[0126] Step 6-3: Based on the results of the configuration verification test, generate the status test report and operation ticket test report for each interval device of the one-click sequential control system under test;

[0127] The test report includes a device status test report and an operation ticket test report, specifically including the following contents:

[0128] The device state test report is a test report generated based on the device state configuration information of the one-click sequential control expert test library in step 4 and the evaluation of the test results of the device state in step 6-2. Its content includes the configuration information of each device state in each interval, that is, the combination of signal states contained in each device state, and the corresponding evaluation of the test results of each device state.

[0129] The operation ticket test report is a test report generated based on the operation ticket configuration information of the one-click sequential control expert test library in step 4 and the evaluation of the operation ticket test results in step 6-2. Its content includes configuration information such as the operation process, execution conditions and confirmation conditions of each operation ticket, as well as the evaluation of the corresponding operation ticket test results.

[0130] Step 6-4 verifies and corrects the correctness of the expert test library configuration through manual verification and judgment in the first test, and marks the expert test library that has completed the first test verification and correction as a verified expert test library, forming a set of verified expert test libraries.

[0131] Specifically, since the expert test library is generated through manual configuration, in order to ensure the rigor and correctness of the simulation test, the correctness of the expert test library itself needs to be determined by manual verification and judgment during the first test. Once the first test verification and correction are completed, the expert test library can be marked as a verified expert test library.

[0132] If the expert test library set is to be independently verified and tested, then step 6 also includes:

[0133] Considering the universality and inheritability of the expert test library configuration, a test scenario specifically designed to verify the correctness of the expert test library can be designed. The expert test library can be verified independently, that is, the expert test library set obtained in step 5 can be directly and independently subjected to self-simulation test. The correctness of the expert test library is determined by manually comparing the logical relationship of the self-simulation test with the configuration described in the standard one-click sequential control operation ticket. The correct expert test library is evaluated and verified. The verified expert test library is marked as verified and a set of verified expert test libraries is formed. Its effect is equivalent to determining the correctness of its configuration through manual verification and judgment during the initial test.

[0134] Step 7: Perform simulation tests or verification tests on the expert test library to obtain a set of verified expert test libraries;

[0135] If there is an existing expert test library, the expert test library can be verified first. The expert test libraries that are evaluated correctly are marked as verified, forming a set of verified expert test libraries.

[0136] Alternatively, the existing expert test library can be directly applied to the one-click sequential control simulation test of the project for the first time. The correctness of the expert test library can be determined by manual evaluation. The expert test library that is confirmed to be correct is marked as verified, forming a set of verified expert test libraries. The verified expert test library is generated at the same time as the test report is issued. The expert test library can then be used for one-click sequential control simulation tests of other projects.

[0137] For specific steps of verification testing and one-click sequential control simulation testing, please refer to the method for testing the expert test library set in step 6.

[0138] Step 8: Apply the expert test library in the verified expert test library set as the correctly configured test library directly to one-click sequential control simulation tests in other similar scenarios.

[0139] The test libraries in the verified expert test library set are considered to be correctly configured and can be directly applied to one-click sequential control simulation tests in other similar scenarios. The verified expert test libraries are used for one-click sequential control simulation tests in actual engineering projects and can directly generate test reports. If a mismatch occurs with the engineering configuration during the simulation test application, it will be considered that the engineering configuration is incorrect.

[0140] This invention also proposes a one-click sequential control expert test library generation and application system for simulation testing. The above-mentioned one-click sequential control expert test library generation and application method for simulation testing can be implemented through this system. Specifically, the system includes: an intermediate database construction module, a dictionary database construction module, an expert test library construction module, a classification module, and a testing module.

[0141] Among them, the intermediate database construction module can construct an intermediate database based on the information points in the standard operation tickets under each main wiring method;

[0142] The dictionary building module can build a dictionary based on intermediate database information;

[0143] The expert test library construction module can build a one-click sequential control expert test library based on information points in the intermediate database;

[0144] The classification module can categorize typical voltage levels, wiring methods, and bay type standards of the power grid, and can also classify the expert test library according to the standards.

[0145] The testing module is used to perform simulation or verification tests on the expert test library to obtain a correctly configured test library that can be directly applied to one-click sequential control simulation tests in other similar scenarios.
