The OMS system refers to the power grid dispatching information management system, which is connected to the Baoxin main station web server through a firewall to achieve rapid flow of dispatching business and can be used to apply for and issue maintenance orders.

[0029] Step S102, when it is determined that the above OMS maintenance order information is obtained within the preset time period, control and confirm whether the GOOSE export soft pressure plate has been completely withdrawn;

[0030] Step S103, when all the GOOSE export soft pressure plates are withdrawn and a GOOSE link break signal is received after all the GOOSE export soft pressure plates are withdrawn, confirm in real time whether a GOOSE link break recovery signal is received;

[0031] Specifically, when all the GOOSE outlet soft pressure plates are withdrawn and a GOOSE chain break signal is received after all the GOOSE outlet soft pressure plates are withdrawn, whether the maintenance work of the protection device is completed is determined by monitoring the GOOSE chain break recovery signal, thereby improving the safety of the maintenance process.

[0032] Step S104, when it is determined that the GOOSE link break recovery signal is received and the protection device maintenance signal disappears, the GOOSE outlet soft pressure plate is controlled to be fully restored.

[0033] Specifically, when the GOOSE chain break recovery signal is received and the protection device maintenance signal disappears, it indicates that the maintenance work of the protection device is completed, and all GOOSE outlet soft pressure plates are controlled to recover.

[0034] Through this embodiment, when the main station receives the protection device maintenance signal, the OMS maintenance order information is obtained, wherein the protection device includes the bus differential protection device, the main transformer protection device and the line protection device of the intelligent substation; when the OMS maintenance order information is obtained within the preset time period, the GOOSE export soft pressure plate is controlled and confirmed whether it has been completely withdrawn; when the GOOSE export soft pressure plate is completely withdrawn and the GOOSE chain break signal is received after the GOOSE export soft pressure plate is completely withdrawn, it is confirmed in real time whether the GOOSE chain break recovery signal is received; when it is determined that the GOOSE chain break recovery signal is received and the protection device maintenance signal disappears, the GOOSE export soft pressure plate is controlled to be completely restored. According to the OMS system maintenance order information, the protection device maintenance signal, the GOOSE chain break signal, and the GOOSE export soft pressure plate status are monitored in real time, and the protection device safety measures are intelligently judged whether the execution is normal; the existing scheme solves the problem that there is a lack of effective monitoring means for the safety measures during the maintenance of the protection device, and the protection device malfunctions or refuses to operate due to the erroneous execution of safety measures during the maintenance process.

[0035] During the specific implementation process, when it is determined that the above-mentioned GOOSE chain break recovery signal is received and the above-mentioned protection device maintenance signal is detected to disappear, the above-mentioned GOOSE export soft pressure plate is controlled to be fully restored, including: when it is determined that the above-mentioned GOOSE chain break recovery signal is received, it is confirmed again whether the above-mentioned GOOSE export soft pressure plate has been fully withdrawn; when the above-mentioned GOOSE export soft pressure plate has been fully withdrawn, it is detected whether the above-mentioned protection device maintenance signal disappears; when it is determined that the above-mentioned protection device maintenance signal disappears, the above-mentioned GOOSE export soft pressure plate is controlled to be fully restored, and it is determined whether the state of the above-mentioned GOOSE export soft pressure plate is consistent with the reference state.

[0036] Specifically, after reconfirming whether the above-mentioned GOOSE exit soft pressure plate has been completely withdrawn, the above-mentioned method also includes: when it is confirmed that the above-mentioned GOOSE exit soft pressure plate has not been completely withdrawn, generating a first alarm information, wherein the above-mentioned first alarm information is used to prompt that the safety measures of the protection device are executed abnormally; after determining whether the state of the above-mentioned GOOSE exit soft pressure plate is consistent with the reference state, the above-mentioned method also includes: when it is determined that the state of the above-mentioned GOOSE exit soft pressure plate is inconsistent with the above-mentioned reference state, generating a second alarm information, wherein the above-mentioned second alarm information is used to prompt that the state of the above-mentioned GOOSE exit soft pressure plate is inconsistent with the above-mentioned reference state.

[0037] The method determines whether the GOOSE outlet soft pressure plate is restored to its original position by judging whether the state of the GOOSE outlet soft pressure plate is consistent with the reference state, thereby greatly improving the safety of the system.

[0038] More specifically, after detecting whether the protection device maintenance signal disappears, the method further includes: when detecting that the protection device maintenance signal has not disappeared, monitoring the protection device maintenance signal in real time until the protection device maintenance signal disappears.

[0039] This method detects that the protection device maintenance signal has not disappeared, indicating that it is still in warranty status. The GOOSE export soft pressure plate can be restored only when the protection device maintenance signal disappears, thereby improving the safety of the system.

[0040] Furthermore, after obtaining the OMS maintenance order information, the above method also includes: when it is determined that the above OMS maintenance order information has not been obtained within the above preset time period, generating a third alarm information, wherein the above third alarm information is used to prompt that the protection device maintenance pressure plate is abnormal; after the above GOOSE export soft pressure plate is completely withdrawn, the above method also includes: confirming whether the above GOOSE link break signal is received, and when it is determined that the above GOOSE link break signal is not received, real-time monitoring until the above GOOSE link break signal is received.

[0053] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the safety monitoring system of the intelligent substation protection device and the safety monitoring method of the intelligent substation protection device of the present application will be described in detail below in combination with specific embodiments.

[0054] Currently, the implementation of safety measures during the maintenance of protective devices is mainly controlled by operating personnel through work tickets and secondary measures sheets. This method is inefficient and has the risk of incorrect execution or omission of safety measures.

[0055] This embodiment provides a specific method for monitoring safety measures of protection devices in smart substations. By opening the interfaces of the Baoxin master station, the OMS system, and the Elink office system, the Baoxin master station monitors the maintenance signal of the protection device, the GOOSE disconnection signal, the status of the soft pressure plate, etc. in real time according to the maintenance order information of the OMS system, and intelligently determines whether the execution of the safety measures of the protection device is normal. Any abnormal execution of the safety measures will be sent to relevant personnel through the Elink office system.

[0056] Safety monitoring system of intelligent substation protection device Figure 2 As shown;

[0057] Among them, the OMS system refers to the power grid dispatching information management system, which is deployed in the security zone II and connected to the Baoxin main station web server through a firewall to achieve rapid flow of dispatching business, and can be used to apply for and issue maintenance orders.

[0058] The Baoxin main station is deployed in safety zone I, and is connected to the Baoxin substation through the dispatching data network. It collects and monitors the data sent by protection devices, recorders, etc. in real time, and can realize real-time monitoring of the safety of protection devices.

[0059] The Baoxin main station web server is deployed in security zone II and is connected to the Baoxin main station through forward and reverse isolation devices. It can obtain the data of the Baoxin main station, connect to the OMS system and the elink office system through the firewall, and forward the protection device security execution exception information sent by the Baoxin main station to the Elink office system.

[0060] Elink office system refers to a power grid-specific office information transmission system, which is deployed in safety zone III and can be used to push abnormal information about the execution of protection device safety measures to relevant personnel;

[0061] The Baoxin substation is deployed in safety zone I, including intelligent telemotors, intelligent recorders, control substations, etc.

[0062] Protection devices refer to intelligent station bus differential protection, main transformer protection, line protection, etc.

[0063] This embodiment relates to a specific security monitoring method for a smart substation protection device, such as Figure 3 As shown, including the following:

[0064] Step 1: The main station receives the bus differential protection maintenance status signal;

[0065] The maintenance status of the mother differential protection is generated after the mother differential protection is put into operation after the maintenance hard pressure plate. For the intelligent station maintenance pressure plate, the maintenance hard pressure plate is allowed to be put into operation only when the protection device is under maintenance. The maintenance hard pressure plate participates in the protection logic. Only the messages between two devices with the same maintenance status can be received and processed, that is, "same processing, different discards". If the maintenance pressure plate is put into operation on a normally operating protection device, it may cause the protection device to refuse to operate.

[0066] Step 2: The Baoxin master station obtains the OMS maintenance order information and checks whether there is a maintenance order for the bus differential protection during this period? If yes, proceed to step 3; if not, the Baoxin master station sends a "bus differential protection maintenance pressure plate input abnormality" and sends it to relevant personnel through the elink office system to end the process;

[0067] Step 3: The Baoxin master station calls the GOOSE export soft pressure plate of the mother differential protection, and determines whether all the GOOSE export soft pressure plates have exited? If yes, execute step 4; if not, the Baoxin master station sends "mother differential protection safety measure execution exception" and sends it to relevant personnel through the elink office system, and then execute step 4;

[0068] The bus differential protection GOOSE outlet soft pressure plate includes: bus coupling (section) tripping outlet soft pressure plate, branch tripping outlet soft pressure plate, main transformer failure tripping three-side outlet soft pressure plate, etc.

[0069] Step 4: The Baoxin master station monitors the bus differential protection GOOSE disconnection signal in real time, and determines whether it receives the bus differential protection maintenance and GOOSE disconnection signals at the same time? If yes, the Baoxin master station does not detect the bus differential protection GOOSE outlet soft pressure plate status, and executes step 5; if not, the Baoxin master station continues to monitor the bus differential protection GOOSE disconnection signal;

[0070] Step 5: Does the Baoxin master station receive the bus differential protection GOOSE disconnection recovery signal? If yes, execute step 6; if not, the Baoxin master station continues to monitor the bus differential protection GOOSE disconnection signal;

[0071] Step 6: The Baoxin master station calls the status of the bus differential protection soft pressure plate, and determines whether all GOOSE export soft pressure plates have exited? If yes, execute step 7; if not, the Baoxin master station sends "bus differential protection safety measures execution exception" and sends it to relevant personnel through the elink office system, and then execute step 7;

[0072] Step 7: The Baoxin master station monitors the maintenance status of the bus differential protection in real time, and determines whether the maintenance signal of the bus differential protection disappears. If yes, execute step 8; if not, the Baoxin master station continues to monitor the maintenance status of the bus differential protection;

[0073] Step 8: The Baoxin master station calls the status of the mother differential protection soft pressure plate, and determines whether all the export soft pressure plates have been restored (the export soft pressure plate status is consistent with the reference value)? If yes, the process ends; if not, the Baoxin master station sends "mother differential protection safety measures recovery abnormality" and sends it to relevant personnel through the elink office system, and then the process ends.

[0074] The embodiment of the present application opens up the interfaces of the Baoxin main station, the OMS system, and the Elink office system, so that according to the maintenance order information of the OMS system, the Baoxin main station monitors the maintenance signal of the protection device, the GOOSE chain break signal, the status of the soft pressure plate, etc. in real time, and intelligently determines whether the execution of the safety measures of the protection device is normal, and sends the abnormal execution of the safety measures (safety measures) to the relevant personnel through the Elink office system.
