[0002] When the on-site operation mode of a substation changes, some protection panels need to be switched accordingly, and misoperation of the switching of the panels will cause the relay protection to act or malfunction, causing serious power grid accidents. Power grid accidents caused by misoperation of the switching of the panels occur from time to time, and therefore, the secondary anti-misoperation of substations gradually becomes the focus of attention for preventing electrical misoperation of power grids and is the development direction of anti-misoperation technology.

[0003] The secondary anti-misoperation of substations performs three-protection logic verification. Firstly, primary lockout secondary logic verification is performed, when the primary equipment is in hot standby or running state, and an operation and maintenance personnel performs protection panel switching operation, the monitoring host automatically verifies the panel state of the operation interval, to ensure that at least one set of protection function is put into operation, to prevent the primary equipment from losing protection. Secondly, secondary lockout primary logic verification is performed, when the primary equipment is switched, and the operation and maintenance personnel performs primary equipment cold standby to hot standby, hot standby to running operation on the monitoring host or locally, the monitoring host automatically verifies the panel state of the operation interval, to ensure that at least one set of protection function is put into operation, to prevent the primary equipment from being put into operation without protection. Then, secondary lockout secondary logic verification is performed, the panel operation of the intelligent substation requires that the SV receiving panel is put in first, then the function panel, and finally the outlet panel, and the exit operation is opposite to the above, the monitoring host automatically verifies the panel state of the operation interval, to prevent the secondary panel operation sequence from being wrong.

[0004] The monitoring host needs to be configured with three-protection logic. According to the traditional anti-misoperation logic configuration method, the secondary lockout primary logic needs to be configured for each primary equipment in the whole station, and the primary lockout secondary logic and the secondary lockout secondary logic need to be configured for each protection panel in the whole station, the configuration workload is huge, and configuration errors are prone to occur, which cannot guarantee the correctness of the secondary anti-misoperation function of the substation, and seriously restricts the practicality of the secondary anti-misoperation function of the substation.

[0005] Therefore, it is urgent to improve the current substation secondary anti-misoperation logic configuration and verification method. SUMMARY

[0006] The present application aims at the deficiencies of the prior art, and provides a substation anti-misoperation logic verification method, which can overcome the defects of the existing substation secondary anti-misoperation logic configuration, such as complexity, error-prone and difficult to accept.

In the case of local operation of the protection pressure plate, after detecting the state displacement of the protection pressure plate, the primary lockout secondary check is realized by judging the secondary lockout primary logic of the interval to which the protection pressure plate belongs. In the case of remote operation of the protection pressure plate, after receiving the remote preset instruction of the protection pressure plate, the expected state of the simulation pressure plate is set according to the operation type of the protection pressure plate, and the secondary lockout primary logic of the interval to which the protection pressure plate belongs is checked based on the expected state of the simulation pressure plate, so as to realize the primary lockout secondary check.

[0053] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings.

[0054] The embodiment of the application provides a substation misoperation prevention logic verification method, which is described with reference to Figure 1 , and includes the following steps:

[0055] Step 1, configuring the secondary lockout primary logic for the primary device.

[0056] The secondary lockout primary logic of all switches and disconnectors in the same interval is the same, and only one secondary lockout primary logic needs to be configured for one interval and stored under the interval.

[0057] Specifically, the secondary lockout primary logic rule is configured as the protection function of the interval being put into operation.

[0058] Specifically, the interval under protection configuration mode is divided into double set configuration protection and single set configuration protection, so the interval under protection device is divided into three groups, which are the first set protection, the second set protection and the single set protection, and the logic rule of interval protection function input is:

[0059] ((interval first set protection function input || interval second set protection function input) && interval single set protection function input)

[0060] In the rule formula, "||" represents or operation, and "&&" or "&" represents and operation. The rule indicates that any one of the double set protection function input and the single set protection input.

[0061] Referring to Figure 2 the example, in the overall logic function under an interval, A set and B set are double sets, and C set is a single set, so only one secondary interlocking primary logic needs to be configured under the interval: (A set || B set) & C set.

[0062] Specifically, the interval first set protection function input is the logical and operation of the function inputs of all single protection devices included in the first set protection group; the interval second set protection function input is the logical and operation of the function inputs of all single protection devices included in the second set protection group; and the interval single set protection function input is the logical and operation of the function inputs of all single protection devices included in the single set protection group.

[0063] For example, the devices included in the first set protection group under the 220kV #1 main transformer medium voltage side interval in a certain intelligent substation include the 220kV #1 main transformer medium voltage side first set main transformer protection and the 220kV #1 main transformer medium voltage side XX switch first set integrated intelligent device; the devices included in the second set protection group include the 220kV #1 main transformer medium voltage side second set main transformer protection and the 220kV #1 main transformer medium voltage side XX switch second set integrated intelligent device; and the devices included in the single set protection group include the 220kV #1 main transformer medium voltage side bus protection, the 220kV #1 main transformer medium voltage side XX switch first set integrated intelligent device and the 220kV #1 main transformer medium voltage side bus protection merging unit. The logic rule of the protection function input of the interval is:

[0064] (((The first set of main transformer protection functions on the medium-voltage side of 220kV#1 main transformer is put into operation && The first set of integrated intelligent device functions on the XX switch on the medium-voltage side of 220kV#1 main transformer is put into operation) | | (The second set of main transformer protection functions on the medium-voltage side of 220kV#1 main transformer is put into operation && The second set of integrated intelligent device functions on the XX switch on the medium-voltage side of 220kV#1 main transformer is put into operation) && (The protection function of the bus where the medium-voltage side of 220kV#1 main transformer is located is put into operation && The first set of integrated intelligent device functions on the XX switch on the medium-voltage side of 220kV#1 main transformer is located && The combined protection unit function of the bus where the medium-voltage side of 220kV#1 main transformer is located is put into operation))

[0065] Specifically, activating the function of a single protection device involves performing a logical AND operation on the relevant pressure plates contained in the device under normal conditions.

[0066] For example, the logic rule for activating the first set of main transformer protection functions on the medium-voltage side of the 220kV#1 main transformer is:

[0067] (Main protection soft switch is in the active state && Trip medium voltage side XX switch soft switch is in the active state && Medium voltage side XX switch SV receiver soft switch is in the active state && Medium voltage side voltage soft switch is in the active state && Medium voltage side XX switch backup protection soft switch is in the active state && Device maintenance hard switch is in the deactivated state && Device interlock signal status is 0)

[0068] Here, the normal state of the pressure plate has been pre-configured in the monitoring host database.

[0069] Step 2: Configure secondary interlocking logic for the protection pressure plate; there is no need to configure primary interlocking logic.

[0070] First, set the specific type of the protection pressure plate, which is divided into functional pressure plate, outlet pressure plate, and SV receiving pressure plate.

[0071] Then, the monitoring host automatically generates secondary interlocking logic rules based on the specific type of the protection switch. For conventional stations, protection switches are activated first, then outputs, and deactivated in the reverse order. For intelligent stations, protection switches are activated first (SV receiving), then functions, then outputs, and deactivated in the reverse order. The automatic generation algorithm for secondary interlocking logic rules is as follows: Figure 3 As shown. The input operations must be performed in a top-down order: first input the SV receiving platen; when inputting functional plates, ensure all SV receiving plates are input; and when inputting the output platen, ensure all functional plates are input. Conversely, the output operations must be performed in a bottom-up order: first output the output platen; when outputting functional plates, ensure all output plates are output; and when outputting the SV receiving platen, ensure all functional plates are output. This enforces the correct operating sequence and prevents misoperation.

[0072] Specifically, each pressing plate automatically generates a secondary locking secondary logic of an input operation and a secondary locking secondary logic of an exit operation, which are saved under the pressing plate.

[0073] For example, the secondary locking secondary logic rule of the input operation of the distance protection soft pressing plate of the first set of line protection of 220kV XX line is:

[0074] (The input of all SV receiving soft pressing plates of the device)

[0075] The secondary locking secondary logic rule of the exit operation of the SV receiving soft pressing plate is:

[0076] (The exit of all protection function pressing plates of the device && The exit of all exit pressing plates of the device)

[0077] Step 3, when operating the primary equipment, check the secondary locking primary logic.

[0078] The operation of the primary equipment includes remote or on-site operation of the primary equipment. When the monitoring host receives the remote preset instruction of the primary equipment or detects the state change of the primary equipment, the secondary locking primary logic is checked. If the check fails, an alarm is given.

[0079] When the primary equipment is remotely operated, the monitoring host determines that the primary equipment is operated from cold standby to hot standby or from hot standby to operation. The secondary locking primary logic of the interval to which the primary equipment belongs is searched and checked. If the check fails, an alarm is given to prompt the secondary locking primary, and the operation personnel can choose whether to terminate the operation.

[0080] When the primary equipment is operated on-site, the monitoring host detects the state change of the primary equipment and determines that the primary equipment is operated from cold standby to hot standby or from hot standby to operation. The secondary locking primary logic of the interval to which the primary equipment belongs is searched and checked. If the check fails, an alarm is given to prompt the secondary locking primary.

[0081] Step 4, when operating the protection pressing plate, check the secondary locking secondary logic, and at the same time, check the secondary locking primary logic based on the expected state of the simulation pressing plate to realize the primary locking secondary check.

[0082] The operation of the protection pressing plate includes remote or on-site operation of the pressing plate. When the monitoring host receives the remote preset instruction of the pressing plate or detects the state change of the pressing plate, it is determined that the interval to which the pressing plate belongs is in operation or hot standby. The secondary locking secondary logic of the pressing plate is searched and checked. If the check fails, an alarm is given to prompt the secondary locking secondary.

[0083] Specifically, if the pressboard is put into operation, the secondary locking secondary logic of the pressboard put-in operation is searched, and if found, the secondary locking secondary logic verification is performed, and if not found, no verification is needed; if the pressboard is withdrawn, the secondary locking secondary logic of the pressboard withdrawal operation is searched, and if found, the secondary locking secondary logic verification is performed, and if not found, no verification is needed.

[0084] The monitoring host simultaneously performs primary locking secondary verification.

[0085] Specifically, if the normal state of the pressboard is 1, the pressboard is put in without primary locking secondary verification, and the pressboard is withdrawn to perform primary locking secondary verification; if the normal state of the pressboard is 0, the pressboard is withdrawn without primary locking secondary verification, and the pressboard is put in to perform primary locking secondary verification.

[0086] The purpose of primary locking secondary verification is to prevent the running primary equipment from losing protection after putting in or withdrawing a certain pressboard, so when the operation and maintenance personnel perform protection pressboard put-in or withdrawal operation in the hot standby or running state of the primary equipment, the monitoring host automatically verifies the operation interval pressboard state logic, and if the logic is not met, an alarm is prompted to avoid mistaken withdrawal of all protections. For protection dualization configuration of 220kV and above equipment, when one set of protection function is withdrawn, the related another set of protection function of the operation interval is required to be complete. Taking a line interval as an example, the first set of line protection or the first set of bus protection is withdrawn, and the second set of line protection, bus protection and corresponding merging unit, intelligent terminal function are required to be put in.

[0087] Specifically, if it is a local operation, the pressboard has completed the put-in or withdrawal operation, and the monitoring host performs primary locking secondary verification after detecting the pressboard state change, that is, it is judged that the related another set of protection function of the operation interval is put in. At this time, the pressboard is not in the normal state, and judging that the related another set of protection function of the operation interval is put in is equivalent to judging that at least one set of protection function of the operation interval is put in, that is, equivalent to judging the secondary locking primary logic of the interval to which the pressboard belongs. The monitoring host verifies the secondary locking primary logic of the interval to which the pressboard belongs, and if the verification fails, it means that the primary equipment has lost protection, and an alarm is prompted for primary locking secondary verification. The pressboard local operation logic verification flow is as shown in Figure 4 .

[0088] Specifically, in the case of remote control operation, before the pressure plate is fully engaged or disengaged, the monitoring host receives the preset remote control command for the pressure plate and performs a secondary interlock check, i.e., determines whether the other set of protection functions related to the operation interval is engaged. At this time, the pressure plate has not been operated and is still in normal state. If the secondary interlock logic of the interval to which the pressure plate belongs is directly judged, the judgment result will always be true. Therefore, before judging the secondary interlock logic of the interval to which the pressure plate belongs, the monitoring host first presets the pressure plate to the target state and simulates engaging or disengaging the pressure plate. If the operation is to engage the pressure plate, the expected state (i.e., the target state) of the pressure plate is engaged; if the operation is to disengage the pressure plate, the expected state of the pressure plate is disengaged. Then, the secondary interlock logic of the interval to which the pressure plate belongs is checked. If the check fails, it means that operating the pressure plate will cause the primary equipment to lose protection, and an alarm is triggered indicating secondary interlock. The pressure plate remote control operation logic verification process is as follows: Figure 5 As shown.

[0089] Specifically, the simulated pressure plate's expected state and verification logic are as follows: During remote control operation, the monitoring host transmits the currently operated pressure plate and its target state to the logic calculation module. If the current operation is to engage the pressure plate, the target state of the pressure plate is 1; if the current operation is to disengage the pressure plate, the target state of the pressure plate is 0. The logic calculation module calculates the secondary interlocking primary logic for the interval to which the pressure plate belongs. When determining whether the pressure plate's state meets the secondary interlocking primary logic requirements, it compares the pressure plate's target state with its normal state. If they match, the logic requirement is met; otherwise, the logic verification fails.

[0090] Specifically, when remotely controlling the pressure plate, if the secondary interlock or the primary interlock fails the secondary verification, the maintenance personnel can choose whether to terminate the operation.

[0091] Preferably, the monitoring host can export the primary logic rules for secondary interlocking and the secondary logic rules for secondary interlocking of the entire station for verification by operation and maintenance personnel.

[0092] This method overcomes the challenge of complex configuration of secondary protection and three-dimensional protection logic in existing substations. Taking a 500kV substation as an example, containing 82 protection devices and 65 bays, traditional three-dimensional protection logic verification requires configuring 126 secondary interlocking primary logics for switches and disconnectors, and 52 primary interlocking secondary logics and 20 secondary interlocking secondary logics for each bay's pressure plate, totaling approximately 4800 three-dimensional protection logics for the entire substation. Using this method, only 65 secondary interlocking primary logics and 1300 secondary interlocking secondary logics are required, reducing the number of three-dimensional protection logic configurations by approximately 70%. This significantly improves engineering configuration efficiency, shortens logic acceptance time, and reduces labor costs. Furthermore, the reduced configuration complexity significantly reduces the risk of configuration errors caused by human error, significantly improving system reliability and enhancing the practicality of secondary protection in substations, especially in large-scale high-voltage substations.

[0093] Based on the same technical concept as the method embodiment, the application also provides a substation anti-misoperation logic verification system, comprising:
