Abstract
Description
Technical Field
[0001] This invention belongs to the field of power system automation technology, specifically relating to a method and system for monitoring safety measures throughout the entire remote operation process. Background Technology
[0002] Smart substations transform secondary circuits from physical to virtual, rendering them physically invisible. Furthermore, the diverse types of voltage plates in smart substations pose challenges for maintenance personnel, significantly increasing the risks associated with maintenance operations. Therefore, effective monitoring of the implementation of safety measures (hereinafter referred to as safety measures) during operations and providing alarms for abnormal operations are crucial. Previously, safety measure monitoring was typically conducted locally, requiring additional maintenance personnel, and multiple sites might be operating simultaneously, resulting in high labor costs. Therefore, how to remotely monitor the implementation of safety measures at multiple sites simultaneously, thereby reducing labor costs, has become one of the key approaches to enriching the advanced functions of the secondary maintenance master station.
[0003] Secondary maintenance master stations typically only connect to bay-level equipment. However, safety measures implementation in smart substations often involve process laminate information. Therefore, filling this data gap is a crucial prerequisite for achieving remote monitoring of safety measures. Furthermore, previous monitoring of safety measures only occurred before and after operations, neglecting to monitor their status during the operation process. The complex circuit structure of smart substations introduces significant risks of operational errors during operations; therefore, real-time monitoring of safety measures during the operation process is necessary. Summary of the Invention

[0010] Before operation, the process layer cross-sectional data file is retrieved from the intelligent waveform recorder and the general call message is obtained from the manufacturing message system (MMS). The relevant pressure plate status is obtained based on the process layer cross-sectional data file and the MMS general call message, and compared with the safety measure benchmark. If they are inconsistent, an alarm is triggered.
[0011] During the operation, a visual monitoring screen is generated based on the safety monitoring benchmark. The pressure plate displacement information involved in the safety benchmark is confirmed based on the information sent by the intelligent waveform recorder measurement point and the MMS displacement message, and displayed and alarmed on the screen.

[0046] The present invention will now be further described with reference to the accompanying drawings.
[0047] With the release of the "Engineering Application Guide for Intelligent Waveform Recorders, Volume 2: Master-Slave Communication" (hereinafter referred to as the "Guide"), the method of uploading process-level information has been more clearly defined and constrained, making it possible to remotely monitor safety measures throughout the entire operation process. Based on this, this application provides a method for remotely monitoring safety measures throughout the entire operation process, such as... Figure 1 As shown, it includes the following steps:
[0048] S100: Obtain the full station system configuration description SCD file and secondary loop model file from the intelligent waveform recorder.
[0049] SCD configuration files are a file type defined by the IEC 61850 standard, used to describe information about all equipment in the entire substation. They include the substation primary system configuration (including primary and secondary equipment association information configuration), secondary equipment configuration (including signal descriptions and GOOSE signal connection configuration), and communication network and parameter configuration.
[0050] The structure of the secondary loop model file is shown in Table 1. Parsing this file can obtain information on the process layer devices, filling in the missing process layer devices when modeling the main station. At the same time, the file contains the secondary loop connection relationship and the pressure plate information in the GOOSE link. Combining the secondary loop connection relationship and the information on the bay layer and process layer devices, a complete station-wide secondary loop model can be formed.

[0053]
[0054]
[0055] S200: Generate a complete full-site secondary loop model based on the SCD file and the secondary loop model file.
[0056] In some embodiments, the steps for generating a complete station secondary loop model specifically include: parsing the SCD file to extract information on bay-level protection devices, where bay-level protection devices in the SCD refer to all types of protection devices, such as devices whose IEDname starts with P according to the Southern Power Grid naming convention; the extracted information mainly includes functional pressure plates and maintenance pressure plates. Parsing the secondary loop model file to extract process-level related information, which includes merging units, intelligent terminals, and virtual loop information. Based on the bay-level protection device information and the process-level related information, a complete station secondary loop model is formed.
[0057] S300: Receives equipment maintenance information, determines the scope of impact of the operation based on the complete station secondary circuit model, and generates safety monitoring benchmarks.
[0058] In some embodiments, the steps for generating safety monitoring benchmarks specifically include: receiving information about equipment requiring maintenance, obtaining logical link information of the bay layer protection devices associated with the maintenance equipment based on the complete station secondary loop model, finding the bay layer and process layer devices with secondary connections to the maintenance protection devices based on the logical link outward topology, thereby determining the scope of the operation's impact, and sequentially combining the GOOSE receive / transmit pressure plates, functional pressure plates, and maintenance pressure plates found during the topology process to form safety monitoring benchmarks.
[0059] S400: Before operation, retrieve the process layer cross-sectional data file from the intelligent waveform recorder and obtain the general call message from the manufacturing message system (MMS); obtain the relevant pressure plate status based on the process layer cross-sectional data file and the MMS general call message, and compare it with the safety measure benchmark. If they are inconsistent, an alarm will be issued.
[0060] In some embodiments, the structure of the process layer cross-section data file is shown in Table 2. Parsing the process layer cross-section data file can obtain the real-time status of the GOOSE transmit / receive pressure plates in the process layer network. Parsing the MMS general call message obtains the real-time status of each functional pressure plate and maintenance pressure plate in the interval layer network. The real-time status of the GOOSE transmit / receive pressure plates, functional pressure plates, and maintenance pressure plates is compared with the safety measure benchmark; the main content of the comparison is to check whether the GOOSE transmit / receive pressure plates and functional pressure plates are deactivated, and whether the maintenance pressure plates are activated; if they are inconsistent, an alarm is issued.

[0063] S500: During operation, a visual monitoring screen is generated based on the safety monitoring benchmark. The pressure plate displacement information involved in the safety benchmark is confirmed based on the information sent by the intelligent waveform recorder measurement point and the MMS displacement message, and displayed on the screen with alarm prompts.
[0064] Specifically, during the operation, an automatic mapping technology is used to generate a visual monitoring screen based on the safety monitoring benchmark. The visual monitoring screen is a secondary loop connection diagram, used to reflect the scope of the operation's impact.
[0065] Real-time monitoring of the information transmitted from the measurement points of the intelligent waveform recorder allows for the parsing and acquisition of the process-level GOOSE transmit / receive plate displacement status. To transmit process-level GOOSE displacement information, the guidelines propose extending a measurement point under the intelligent operation and maintenance alarm information logic node GGIO of the intelligent waveform recorder model. Its structure is shown in Table 3, and it is used to transmit GOOSE displacement information. Therefore, the strings transmitted by the measurement point with the attribute name GseDigVal in the dsWarning dataset of the intelligent waveform recorder's own model can be monitored in real time. Parsing can then obtain the corresponding process-level device GOOSE measurement point reference name and displacement value, thereby monitoring the displacement status of the process-level GOOSE transmit / receive plate.
[0066] Real-time monitoring of MMS displacement messages reveals the displacement status of the bay layer functional pressure plates and maintenance pressure plates. Specifically, for the bay layer device functional pressure plates and maintenance pressure plates, the displacement status of the corresponding measuring points of the device is directly monitored.
[0067] Based on the displacement status of the process layer GOOSE receiving / transmitting pressure plates and the displacement status of the interval layer functional pressure plates and maintenance pressure plates, confirm whether any pressure plates involved in the safety measures benchmark have been displaced. If so, display the pressure plate status on the screen in real time and issue an alarm prompt.

[0069]
[0070] S600: After the operation, the process layer cross-sectional data file is retrieved from the intelligent waveform recorder and the general call message is obtained from the manufacturing message system (MMS); the relevant pressure plate status is obtained according to the process layer cross-sectional data file and the MMS general call message, and compared with the safety measure benchmark. If they are inconsistent, an alarm is issued.
[0071] In some embodiments, the structure of the process layer cross-section data file is shown in Table 2 above. Parsing the process layer cross-section data file can obtain the real-time status of the GOOSE transmit / receive pressure plates in the process layer network. Parsing the MMS general call message obtains the real-time status of each functional pressure plate and maintenance pressure plate in the interval layer network. The real-time status of the GOOSE transmit / receive pressure plates, functional pressure plates, and maintenance pressure plates is compared with the safety measure benchmark; the main content of the comparison is to check whether the GOOSE transmit / receive pressure plates and functional pressure plates are engaged, and whether the maintenance pressure plates are disengaged; if there is a discrepancy, an alarm is issued.
[0072] In a preferred embodiment, such as Figure 2 The method also includes step S700: After monitoring is completed, the monitoring record is saved for historical tracing. In some embodiments, after monitoring is completed, the process information is converted into a JSON file and a record is generated and saved. The JSON file format is shown in Table 4.
