Description

Technical Field

[0001] This invention relates to the field of power system testing technology, and in particular to a test method and apparatus for the switching logic of a safe and stable control system. Background Technology

[0002] As the core defense line for ensuring the safe and stable operation of the power system, the safety and stability control system is a system composed of the stability control devices of two or more power plants interconnected through communication equipment. Its purpose is to achieve stable control of the power system over a regional or even larger area. Therefore, before the safety and stability control system is officially put into operation, it is necessary to test its power line activation and deactivation judgment logic, that is, to verify the correctness of its logic for judging activation and deactivation states, to ensure that the system can effectively maintain the safety and stability of the power system.

[0003] However, current testing methods for the power line activation / deactivation logic of safety and stability control systems primarily rely on personnel manually setting electrical or switching quantities in the test environment to cause the line to be activated or deactivated, and then observing whether the test results match the preset conditions. Given the large number of lines covered by safety and stability control systems, this manual testing method is not only labor-intensive but also relatively inefficient. Summary of the Invention

[0004] In view of the above problems, the present invention provides a test method and apparatus for the start-stop discrimination logic of a safe and stable control system, the main purpose of which is to improve test efficiency.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following solution:

[0006] In a first aspect, the present invention provides a method for testing the start / stop discrimination logic of a safe and stable control system, the method comprising:

[0007] Obtain the electrical quantity setting sheet issued by the safety and stability control system;

[0008] Read the commissioning current setting and commissioning power setting of each target line from the commissioning electrical quantity setting sheet;

[0009] For each target line, based on the operating current setting and the operating power setting, set the electrical quantity data and switching quantity data of the substations at both ends of the target line;

[0010] For each target line, the set electrical quantity data and switch quantity data are sent to the safety and stability control system so that the safety and stability control system can output the line start / stop messages corresponding to the electrical quantity data and switch quantity data respectively.

[0011] The line start / stop messages corresponding to the electrical quantity data and switch quantity data of each target line are compared with the corresponding standard start / stop messages to obtain the test results of the safety and stability control system in the start / stop discrimination logic.

[0012] Secondly, the present invention provides a test device for the start / stop discrimination logic of a safe and stable control system, the device comprising:

[0013] The data acquisition unit is used to acquire the electrical quantity setting sheets issued by the safety and stability control system.

[0014] The data reading unit is used to read the commissioning current setting value and commissioning power setting value of each target line from the commissioning electrical quantity setting value sheet obtained by the data acquisition unit;

[0015] The data setting unit is used to set the electrical quantity data and switching quantity data of the substations at both ends of the target line according to the commissioning current setting value and the commissioning power setting value read by the data reading unit for each target line.

[0016] The data transmission unit is used to send the electrical quantity data and switch quantity data set by the data setting unit to the safety and stability control system for each target line, so that the safety and stability control system can output the line start / stop messages corresponding to the electrical quantity data and switch quantity data respectively.

[0017] The data comparison unit is used to compare the line start / stop messages corresponding to the electrical quantity data and switch quantity data of each target line obtained by the data sending unit with the corresponding standard start / stop messages, so as to obtain the test results of the safety and stability control system in the start / stop discrimination logic.

[0018] To achieve the above objectives, according to a third aspect of the present invention, a storage medium is provided, the storage medium including a stored program, wherein, when the program is executed, the device where the storage medium is located is controlled to perform the start / stop judgment logic test method of the security and stability control system of the first aspect.

[0019] To achieve the above objectives, according to a fourth aspect of the present invention, a processor is provided, the processor being used to run a program, wherein the program, when running, executes the above-described method for testing the start / stop judgment logic of the safety and stability control system of the first aspect.

[0020] By employing the above technical solution, the present invention provides a method and apparatus for testing the start / stop judgment logic of a safety and stability control system. First, it obtains the target line's electrical quantity setting sheet issued by the safety and stability control system. This setting sheet contains key information such as the start-up current setting and start-up power setting for each target line. Next, based on the start-up current setting and start-up power setting read from the setting sheet, it sets the electrical quantity data and switching quantity data of the substations at both ends of each target line. After setting, it feeds back the electrical quantity data and switching quantity data of each target line to the safety and stability control system. Based on the received data, the safety and stability control system can generate line start / stop messages corresponding to each electrical quantity data and switching quantity data for each target line. Subsequently, it compares the line start / stop messages corresponding to the electrical quantity data of each target line with standard start / stop messages, and similarly compares the line start / stop messages corresponding to the switching quantity data of each target line with standard start / stop messages. The comparison results are used to verify the accuracy of the safety and stability control system in processing the line start / stop judgment logic, i.e., the test results. In this way, the entire testing process requires no manual intervention; there is no need to manually set parameters or observe test results, greatly improving testing efficiency. This automated method not only saves time but also reduces the possibility of human error, making the testing of safety and stability control systems more efficient and accurate.

[0021] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0027] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] Currently, testing methods for safety and stability control systems rely on staff manually setting up the commissioning or shutdown conditions of the lines in the test environment and verifying whether the test results meet the preset conditions through manual observation. This method is not only inefficient but also easily affected by human factors, making it difficult to guarantee the accuracy and consistency of the test results.

[0029] To address this problem, the inventors, through extensive creative work, developed an automated testing system. This system, through interaction with a safety and stability control system, automatically sets the conditions for line commissioning or shutdown and automatically generates test results. This eliminates the need for manual settings and observation, significantly improving testing efficiency and accuracy while reducing the possibility of human error. This not only speeds up the testing process but also ensures consistency and reliability, greatly enhancing overall work efficiency.

[0030] The main implementing body of this invention is an automatic testing system, which can interact with the safety and stability control system to improve the testing efficiency and accuracy of the safety and stability control system. In this process, the safety and stability control system automatically generates an operational electrical quantity setting sheet, a document that guides and records the key electrical parameters that need to be set when power lines or equipment are put into operation. The setting sheet includes the operational current setting, operational power setting, and other relevant parameters such as voltage level and frequency limits. This data is generated by the safety and stability control system based on the power system's design specifications, operating requirements, and historical data to ensure the safe and stable operation of the power system.

[0031] After receiving the electrical quantity setting sheet from the safety and stability control system, the automatic testing system can extract relevant information about the target line, including the operating current setting and operating power setting, from the sheet, which may contain information about multiple lines. Based on the read operating current and power settings, the automatic testing system sets the electrical quantity and switching quantity data for the substations at both ends of the target line. After setting each data point, it is immediately sent to the safety and stability control system. Upon receiving this data, the safety and stability control system generates the corresponding line start / stop message and feeds it back to the automatic testing system.

[0032] After receiving the line activation / deactivation message corresponding to each data, the automatic testing system compares the line activation / deactivation message of each data with the corresponding standard activation / deactivation message, and the test result can be obtained from the comparison result.

[0033] Next, combined Figure 1 This invention provides a method for testing the start / stop judgment logic of a safe and stable control system, and its specific execution steps are as follows: Figure 1 As shown, it includes:

[0034] 101. Obtain the electrical quantity setting sheet issued by the safety and stability control system.

[0035] 102. Read the commissioning current setting and commissioning power setting of each target line from the commissioning electrical quantity setting sheet.

[0036] Regarding steps 101-102, in practical applications and testing environments, the safety and stability control system can set the operating parameters of each line and each piece of equipment according to the power system's design specifications and actual operating requirements, when new lines or equipment are about to be put into operation, or when equipment is put back into operation after maintenance or upgrades. These parameter settings aim to ensure the safe and stable operation of lines and equipment in the power system. Actual operating requirements include, but are not limited to, load balancing and voltage stability.

[0037] In some possible implementations, the safety and stability control system can also refer to historical operating data of the power system, such as past load conditions and fault records, to optimize the settings of lines or equipment and prevent the recurrence of historical problems.

[0038] In managing the electrical quantity setting sheets for operation, to ensure the accuracy and identifiability of information for each line, one of the following measures can be chosen:

[0039] First: Assign a unique identifier (such as line number, name, etc.) to each line or device and clearly mark it in the setting sheet for quick identification.

[0040] Second: The setting sheet should be divided into sections according to the line or equipment, with each section listing all relevant parameters of the line or equipment in detail, making the information more intuitive and easier to understand.

[0041] Third: Use standardized data formats, such as tables, to list the information of each line or device in a separate row, with each column representing different parameters (such as current setting, power setting, etc.). This makes it easy to view the specific parameters of each line at a glance.

[0042] Through the above measures, once the safety and stability control system generates the electrical quantity setting sheet for operation and sends it to the automatic testing system, the automatic testing system can clearly identify the relevant information of each target line from the setting sheet, including the operation current setting and operation power setting. The target line here can be any line in the power system, ensuring the accuracy and efficiency of information processing.

[0043] 103. For each target line, set the electrical quantity data and switching quantity data of the substations at both ends of the target line according to the commissioning current setting value and commissioning power setting value.

[0044] When testing a safety and stability control system, to ensure the accuracy and reliability of the test results, it is necessary to reasonably set the switching and electrical quantity data of the substations at both ends of each target line. For this purpose, the operating power setting or operating current setting can be set to its maximum value. This is to prevent the protection mechanism from being falsely triggered due to minor current fluctuations during the test, and also to avoid the system erroneously taking protective measures due to detecting power levels within the test range.

[0045] The specific steps are as follows: When configuring current data in electrical quantities, the operating power setting should be adjusted to the maximum value; when setting power data, the operating current setting should be set to the maximum value. When adjusting switch quantity data, both the operating current setting and the operating power setting can be set to the maximum value to ensure the comprehensiveness of the test.

[0046] In addition, when setting the current and power data in the switch quantity data and electrical quantity data, all possible states of line commissioning or shutdown should be covered as much as possible to ensure the completeness and accuracy of the test.

[0047] 104. For each target line, send the set electrical quantity data and switch quantity data to the safety and stability control system so that the safety and stability control system can output the line start / stop messages corresponding to the electrical quantity data and switch quantity data respectively.

[0048] In this embodiment, the settings for electrical quantity data and switching quantity data are diverse, enabling each target line to be in an operational or shutdown state. In other words, there are multiple configuration schemes for electrical quantity and switching quantity data. This embodiment provides two operating modes for handling these diverse settings, which can be selected according to the actual situation:

[0049] One approach is to immediately send each setting to the safety and stability control system after it is completed. Upon receiving the setting, the safety and stability control system will instantly generate a corresponding line commissioning or shutdown report.

[0050] Another approach is to compile all possible configuration options and send them to the safety and stability control system all at once. In this way, the system can then generate a unified report on the line's commissioning or shutdown after receiving all the configuration information.

[0051] It should be noted that the automatic testing system involved in this embodiment of the invention is built based on a script pre-written by staff. This script contains test scenarios for the switching and electrical quantities of all target lines, and these test scenarios can be pre-set in the script. Once the automatic testing system receives a commissioning electrical quantity customization order from the safety and stability control system, the system will automatically start the testing process, that is, automatically set the electrical and switching quantities of each target line sequentially according to the pre-set switching and electrical quantities for each target line in the script, completing the traversal testing of multiple target lines.

[0052] Line connection / disconnection messages (also known as switch status change messages or event messages) contain information related to the operating status of lines or equipment in the power system. These messages are crucial for monitoring and controlling the operation of the power system, helping operators understand the system's status and make necessary adjustments or responses. The following are common components and information content of line connection / disconnection messages:

[0053] 1. Basic Identification Information

[0054] Timestamp: Records the specific time when an event occurred, including the date, hour, minute, and second.

[0055] Device ID / Name: A unique identifier or name for the line, switch or other device involved.

[0056] Substation name: The name or number of the substation where the equipment is located.

[0057] 2. Operation type

[0058] Action type: such as "put into operation" (closing) or "stop" (opening), indicating whether the current operation is to put the equipment into operation (operation) or to stop operation (shutdown).

[0059] Reasons for operation: Possible reasons include planned maintenance, fault tripping, manual operation, etc.

[0060] 3. Status Information

[0061] Current status: Describes the state of the device when sending a message, such as "closed", "open" or "faulty".

[0062] Previous state: The original state of the device before operation, which helps to understand the process of state change.

[0063] 4. Protection device information

[0064] Protection device operation status: If the operation is triggered by the protection device, it will be detailed which protection functions were activated, such as overcurrent protection, differential protection, etc.

[0065] Fault type: If there is a fault, the type of fault will be described, such as short circuit, ground fault, etc.

[0066] 5. Electrical quantity data

[0067] Voltage value: The voltage level measured before and after operation.

[0068] Current value: The current level measured before and after operation.

[0069] Power values: Active and reactive power measured before and after operation.

[0070] 6. Auxiliary Information

[0071] Operator information: If it is a manual operation, record the operator's name or employee number.

[0072] Note: Any other information that requires further explanation, such as special instructions or precautions.

[0073] The example message format for line activation / deactivation is as follows:

[0074] Timestamp: 2025-02-06 17:32:00

[0075] Device ID: L123

[0076] Substation name: Substation A

[0088] Power value:

[0089] Before operation: 0MW

[0090] After operation: 55MW

[0091] Operator: Zhang San

[0092] Note: No abnormalities found.

[0093] 105. Compare the line start / stop messages corresponding to the electrical quantity data and switch quantity data of each target line with the corresponding standard start / stop messages to obtain the test results of the safety and stability control system in the start / stop judgment logic.

[0094] In this step, it should be noted that each electrical quantity or switch quantity data in each target line has a line start / stop message and a standard start / stop message output by the safety and stability control system. Therefore, in this step, the line start / stop message of each data in each target line can be compared with the standard start / stop message. The consistency of key fields such as timestamp, device ID, operation type, status information, and protection device action status can be checked one by one. If the line start / stop message of all data in all lines is consistent with the standard start / stop message, the test result of the safety and stability control system in the start / stop discrimination logic is determined to be passed; otherwise, it is considered to be failed, thereby ensuring the reliability and accuracy of the system.

[0095] Based on the above Figure 1As can be seen from the implementation method, the method for testing the start / stop judgment logic of a safety and stability control system provided by this invention first obtains the target line operation electrical quantity setting sheet issued by the safety and stability control system. This setting sheet contains key information such as the operation current setting and operation power setting of each target line. Next, based on the operation current setting and operation power setting read from the setting sheet, the electrical quantity data and switching quantity data of the substations at both ends of each target line are set. After setting, the electrical quantity data and switching quantity data of each target line are fed back to the safety and stability control system. Based on the received data, the safety and stability control system can generate line start / stop messages corresponding to each electrical quantity data and switching quantity data for each target line. Subsequently, the line start / stop messages corresponding to the electrical quantity data of each target line are compared with standard start / stop messages. Similarly, the line start / stop messages corresponding to the switching quantity data of each target line are also compared with standard start / stop messages. The accuracy of the safety and stability control system in processing the line start / stop judgment logic is verified based on the comparison results, i.e., the test results. In this way, the entire testing process requires no manual intervention; there is no need to manually set parameters or observe test results, greatly improving testing efficiency. This automated method not only saves time but also reduces the possibility of human error, making the testing of safety and stability control systems more efficient and accurate.

[0096] Furthermore, as a response to Figure 1 Further refinement and extension of the illustrated embodiment, this invention also provides another method for testing the start / stop judgment logic of a safe and stable control system, such as... Figure 2 As shown, the specific steps are as follows:

[0097] 201. Obtain the electrical quantity setting sheet issued by the safety and stability control system.

[0098] 202. Read the commissioning current setting and commissioning power setting of each target line from the commissioning electrical quantity setting sheet.

[0099] The implementation methods of steps 201-202 are the same as those of steps 101-102, and can achieve the same technical effect and solve the same technical problem, so they will not be repeated here.

[0100] 203. For each target line, set the electrical quantity data of the substations at both ends of the target line according to the commissioning current setting and commissioning power setting.

[0101] In this step, the operating power setting can be set to the maximum value first, and then the current data in the electrical quantity data of the substations at both ends of each target line can be set according to the preset current conditions; similarly, the power data in the electrical quantity data of the substations at both ends of each target line can be set according to the preset power conditions after the operating current setting is set to the maximum value.

[0102] It needs to be clarified that the typical logic for determining whether a line is put into operation or shut down is as follows: if the electrical quantities or switching quantities on one side of the line meet the commissioning conditions, that side is considered to be in operation. Specifically, the commissioning conditions for electrical quantities are: the line's active power is greater than the commissioning power setting, or the current in one of the three phases is greater than the commissioning current setting.

[0103] The preset current conditions include:

[0104] 1. In the case of the first substation at both ends of the target line, the first-phase current is greater than the operating current setting, while the second and third-phase currents are less than the operating current setting. Based on the above, it can be concluded that in this situation, one phase current in the line is greater than the operating current setting. Therefore, the first substation is in operation at this time. Simultaneously, the second substation can also be set to operation under the same conditions.

[0105] 2. The first-phase current, second-phase current, and third-phase current on the first substation side are all less than the operating current setting. Based on the above-mentioned information, it can be concluded that under these circumstances, no phase current in the line exceeds the operating current setting. Therefore, the first substation side is currently out of service. The second substation side remains in operation.

[0106] 3. The first-phase current at the second substation (one of the two substations at either end of the target line) is greater than the operating current setting, while the second and third-phase currents are less than the operating current setting. Based on the above, it is clear that in this situation, one phase current in the line is greater than the operating current setting. Therefore, the second substation is in operation at this time. Simultaneously, the first substation is also set to be in operation under these conditions.

[0107] 4. The first-phase current, second-phase current, and third-phase current on the second substation side are all less than the operating current setting. Based on the above-mentioned information, it can be concluded that in this situation, no phase current in the line exceeds the operating current setting. Therefore, the second substation side is currently out of service. The first substation side remains in operation.

[0108] It should be noted that the above four cases "1-4" are parallel and can be executed sequentially or randomly, as long as the four cases can be traversed. After the traversal is completed, the power setting can be restored to its original value.

[0109] It should be noted that for lines with stabilization devices on both sides, the safety and stability control system takes the overall line operation status when determining the line operation status. That is, the overall line operation status is determined by "AND" logic based on the operation status of the lines on both sides. That is, if both substations on both sides of the line are in operation, the line is judged to be in operation. If one side is out of operation, the line is judged to be out of operation. Therefore, the line status is in operation in the first case, out of operation in the second case, in operation in the third case, and out of operation in the fourth case.

[0110] In addition, the preset power settings include:

[0111] 1. The power of the first substation is greater than the set operating power. Since the active power of the first substation is greater than the set operating power, the first substation is in operation at this time. In this case, the second substation can also be set to be in operation. Based on the same theory, this situation is considered as operational.

[0112] 2. The power output of the first substation is less than the set operational power. Since the reactive power of the first substation is greater than the set operational power, the first substation is currently out of service. In this case, the second substation can be set to operational status. Based on the same theory, this situation is considered an outage.

[0113] 3. The power on the second substation side is greater than the set operating power. Since the active power on the second substation side is greater than the set operating power, the second substation is in operation at this time. In this case, the first substation side can also be set to operation. Based on the same theory, this situation is considered operational.

[0114] 4. The power output of the second substation is less than the set operating power. Since the reactive power of the second substation is greater than the set operating power, the second substation is in a shutdown state at this time. In this case, the first substation can be set to the operating state. Based on the same theory, this situation is considered a shutdown.

[0115] After going through all four scenarios, the operating current setting can be restored to its original value.

[0116] 204. For each target line, set the switching data of the substations at both ends of the target line according to the commissioning current setting and commissioning power setting.

[0117] In this step, the operating current setting and operating power setting of each target line can be set to the maximum value, and then the switching data of the substations at both ends of each target line can be set according to the first preset switching quantity.

[0118] In a switching circuit, if two or more phases of a circuit breaker on one side are in the closed position (using an exhaustive method, i.e., phases AB closed, phases BC closed, phases AC closed, and all three phases ABC closed), the circuit on that side is in operation. This means the circuit breaker is configured to have at least two phases (any two or all three phases of A, B, and C) in the closed state (i.e., in the closed position) to ensure that the circuit between these phases is continuous. In a three-phase circuit, each phase has a circuit breaker. By controlling the opening or closing of the circuit breaker in each phase, the three phases can be in either the closed or open state.

[0119] The first preset switch state includes:

[0120] 1. When at least two phases of the circuit breakers on the first substation side are closed (i.e., in the active position), based on the principle described in the previous paragraph, it can be determined that the first substation side is in operation. In this case, the second substation side can also be set to be in operation accordingly. Combining this with logical principles, when both substations meet the operation conditions, the overall status is determined to be in operation.

[0121] 2. If at least two phases of the circuit breakers on the first substation side are open (i.e., tethered), based on the principle described in the previous paragraph, this means that at least two phases are not in the closed state. Therefore, the first substation side should be considered out of service at this time. The second substation side is then set to the operational state; however, according to logical principles, if any one substation is out of service, the entire system is considered out of service.

[0122] 3. When at least two phases of the circuit breakers on the second substation side are closed, the second substation side can also be determined to be in operation based on the above principle. In this scenario, the first substation side can also be set to be in operation. Combining logical principles, when both substations meet the operation conditions, the overall status is naturally determined to be in operation.

[0123] 4. When at least two phases of the circuit breaker on the second substation side are open, according to the above principle, this means that at least two phases are not in the closed state. Therefore, the second substation side should be determined to be in an out-of-operation state at this time. The first substation side is set to be in an operational state at this time, but based on logical principles, the overall state is still determined to be out of operation due to the outage of one side.

[0124] Of course, the above situation is for normal switch data settings. There are two other situations, namely, the first substation side or the second substation side is a 3 / 2 connection (two-thirds connection, also known as one and a half connection) line. In this case, at least two phases or more of the side circuit breakers or interrupt circuit breakers of the substation are considered to be closed.

[0125] Specifically, when the first substation side is in the designated wiring condition, the operating current setting and the operating power setting are both set to their maximum values, and the closing status of the three-phase side circuit breakers or interruptors on the first substation side is set according to the first designated test sequence. The designated wiring condition is a three-half connection (i.e., open and closed positions). At this time, the first designated test sequence can be shown in Table 1 below:

[0126] Table 1

[0127]

[0128] It needs to be explained that in a three-phase electrical system (A, B, C), the two phases in the "closed" position are those whose circuit breakers are closed. Similarly, the two phases in the "open" position are those whose circuit breakers are open. The same principle applies to the "closed" and "open" positions of all three phases.

[0129] When the second substation side is in the designated wiring configuration, both the operating current setting and the operating power setting are set to their maximum values. The closing status (i.e., open and closed status) of the three-phase side circuit breakers or interruptors on the second substation side is then set according to the second designated test sequence. The second designated test sequence can be shown in Table 2 below:

[0130] Table 2

[0131]

[0132] It should be noted that the first phase, second phase, and third phase, as well as at least two phase circuits mentioned in the embodiments of the present invention, all refer to phase A, phase B, or phase C.

[0133] 205. For each target line, send the set electrical quantity data and switch quantity data to the safety and stability control system so that the safety and stability control system can output the line start / stop messages corresponding to the electrical quantity data and switch quantity data respectively.

[0134] The implementation method of step 205 is the same as that of step 104, and can achieve the same technical effect and solve the same technical problem, so it will not be repeated here.

[0135] 206. Compare the line start / stop messages corresponding to the electrical quantity data and switch quantity data of each target line with the corresponding standard start / stop messages to obtain the test results of the safety and stability control system in the start / stop judgment logic.

[0136] In this invention, the aforementioned detailed testing procedure must be performed for each target line in the electrical quantity setting sheet. Specifically, for each target line, the system must compare the line start / stop messages corresponding to the electrical quantity data and switch quantity data one by one to ensure they are completely consistent with the preset standard start / stop messages.

[0137] If, after comparison and confirmation, the line start / stop messages corresponding to all electrical quantity data and switch quantity data in each target line match the standard messages correctly, then the start / stop discrimination logic test result of the safety and stability control system can be determined as passed. Conversely, if any mismatch exists, the test result is failed.

[0138] If the test result is unsuccessful, the system must record in detail the inconsistencies between the line activation / deactivation message and the standard message, immediately terminate the current test process, and record the problems found.

[0139] It should be noted that since there are multiple lines in this invention, the test process for each line can be executed sequentially. If the current target line passes the test, the process seamlessly transitions to the next target line and continues to execute the test until all target lines in the commissioning electrical quantity setting list have been traversed.

[0140] In other words, in this embodiment of the invention, all possible test scenarios are comprehensively traversed for each target line. Only after all tests are completed and the corresponding line activation / deactivation messages are collected will these messages be compared in detail with preset standard activation / deactivation messages. Through this comparison process, the test results corresponding to each target line can be obtained. Only when the test results of all lines are passed will the test result of the safety and stability control system be considered passed.
