[0001] The present application relates to the technical field of power system fault information management, and in particular to a power system fault information centralized management method, system, device and medium. BACKGROUND
[0002] The safe and stable operation of a power system is of great importance. Fault recording data is a key basis for analyzing the causes of power system faults, evaluating equipment status, and improving system design, and plays an important role in fast recovery of power supply and prevention of accident expansion.
[0003] In the prior art, fault recording data is usually collected by deploying fault recording devices in substations, and it is necessary to periodically visit each substation to collect fault recording data manually. In addition, some technologies attempt to transmit data fault recording data to a data processing center for aggregation and processing in order to realize the integration and application of information.
[0004] However, the prior art still has deficiencies in realizing centralized management of fault information. On the one hand, the original data formats (such as ICD, CID files) generated by fault recording devices of different substations or different manufacturers are different, and direct transmission to the central platform will cause subsequent processing difficulties due to non-uniform formats, affecting data integration efficiency and timeliness of analysis; on the other hand, the prior art lacks effective unified identification and management mechanism for scattered fault recording devices and their data, making it difficult to accurately track data sources and associated equipment information on the centralized platform, affecting the accuracy of data management; in addition, the prior art is difficult to realize real-time and efficient centralized processing and analysis of fault recording data from each substation on the centralized platform, especially for effective monitoring and early warning of slight trigger records (such as transient ground fault, transient voltage sag) reflecting potential risks of the system. SUMMARY
[0005] In view of the technical problems of the prior art that the scattered fault recording data formats are not uniform, lack of effective unified identification management, and insufficient centralized analysis capability, resulting in low efficiency of centralized management of fault information, difficulty in data integration, and difficulty in timely in-depth analysis and early warning, the present application provides a power system fault information centralized management method, system, device and medium, which unifies the data format locally in the substation, assigns a unique identifier to the device and binds data upload, and constructs a structured database on the central platform for centralized analysis, effectively solving the problem of integration of scattered heterogeneous data, and realizing efficient centralized management, accurate tracing and in-depth analysis and early warning of fault information.
[0006] In a first aspect, the present application provides a power system fault information centralized management method, comprising the following steps: S1.

[0015] It should be further noted that the conditions for generating dynamic alarm records are: when the duration of a single minor trigger record exceeds a set time threshold, or when the number of minor trigger records occurring in the same substation within a certain time window exceeds a set number threshold, a dynamic alarm record is generated.
[0016] It should be further noted that the trigger condition for the accident warning is: when the time interval between three consecutive minor trigger records is less than 5 minutes, the accident warning is triggered.
[0017] It should be further noted that step S5 also includes periodically performing data cleaning operations on the structured fault database, retaining only minor trigger records from historical data, and deleting non-trigger continuous records.

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0035] The centralized management method for power system fault information provided in this application embodiment is executed by computer equipment, and correspondingly, the centralized management system for power system fault information runs on the computer equipment.
[0036] Figure 1 This is a flowchart of a centralized management method for power system fault information according to an embodiment of this application. Figure 1 The implementing entity can be a centralized management system for power system fault information. Depending on different needs, the order of the steps in this flowchart can be changed, and some steps can be omitted.
[0037] like Figure 1 As shown, the centralized management method for power system fault information includes: Step S1: Real-time acquisition of fault recording data of the corresponding substations through fault recording devices installed in each substation, and allocation of a unique IP address and unique ID to each fault recording device. The fault recording data is in the form of an ICD file or a CID file, which contains logical nodes, data attributes, waveform sample values and timestamps.
[0038] By setting up fault recording devices in substations to collect fault recording data in real time, including logical nodes, data attributes, waveform sampling values and timestamps, and assigning a unique IP address and unique ID to each device, it is possible to obtain raw data at the source of the fault and establish accurate device identification, providing an irreplaceable basic data source and location identifier for subsequent data tracing, transmission and processing.
[0039] In some specific embodiments, the fault recording device is directly connected to the local dispatch network switch in the substation via a network cable, and the local dispatch network switch is connected to the existing dispatch communication network of the power system.
[0040] By directly connecting the fault recording device to the local dispatch network switch of the substation via a network cable, and having the switch connected to the existing dispatch communication network, a highly reliable physical connection between the fault recording device and the core communication network of the power system is achieved, avoiding the cost and complexity of adding a new independent transmission channel.
[0041] Step S2: At each substation, the fault recording data is processed for format standardization to generate transcoded fault recording data in a unified format. The transcoded fault recording data includes channel configuration information, waveform sampling values, and timestamps.
[0042] By performing format standardization processing on fault recording data locally at each substation, the original heterogeneous data was converted into unified format data locally, eliminating format barriers for subsequent system processing and preserving key data mapping relationships.
[0043] In some specific embodiments, the format standardization process includes: S201. Import fault waveform data; S202. Parse the logical nodes and data attributes in the fault recording data to generate a device data structure mapping table; S203. Configure the parsing rules for fault recording data based on the device data structure mapping table; S204. According to the parsing rules, the original waveform sample values and fault timestamps are converted into waveform sample values and timestamps in COMTRADE format. At the same time, the logical nodes and data attributes are mapped to channel configuration information to generate transcoded fault waveform recording data in COMTRADE format.
[0044] By clearly defining the specific steps of the format standardization process—importing data, parsing logical nodes and data attributes to generate a mapping table, configuring parsing rules based on the mapping table, converting data to COMTRADE format according to the rules and generating channel configuration information—the standardization and operability of the processing flow are achieved, ensuring the accuracy and consistency of the conversion results.
[0045] In some specific embodiments, the device data structure mapping table includes: The correspondence between signal types and logical nodes; The correspondence between sampling rate and data attributes.
[0046] By explicitly recording the correspondence between signal types and logical nodes, and the correspondence between sampling rates and data attributes in the device data structure mapping table, the standardized recording of the original data structure characteristics is achieved, providing a clear basis for configuring parsing rules.
[0047] In some specific embodiments, in step S203, the operation of configuring the fault recording data parsing rules is performed in the PCS-9700 system configured locally in the substation.
[0048] Among them, the PCS-9700 system is a series of automation systems developed by NARI Group Corporation, covering comprehensive automation systems applicable to substations, power plants and various industrial scenarios, as well as photovoltaic power control AGC / AVC systems.
[0049] By configuring the fault recording data parsing rules in the PCS-9700 system configured locally in the substation, the core standardized processing steps were implemented on the mature control system on the substation side, ensuring the stability of the operation and compatibility with the existing system.
[0050] Step S3: Upload the transcoded fault recording data and its corresponding IP address and ID to the regional dispatch communication network through the local dispatch network switch, and then transmit it to the centralized fault information management platform through the regional dispatch communication network.
[0051] By uploading transcoded fault recording data, unique IP addresses, and IDs to the centralized management platform via local dispatch network switches and regional dispatch communication networks, reliable and targeted transmission of standardized data and equipment identification is achieved, ensuring the integrity and traceability of data in the dedicated power system network.
[0052] In some specific embodiments, the scheduling system communication network uses the IEC61850 communication protocol when transmitting data.
[0053] By adopting the IEC61850 communication protocol in the data transmission of the dispatching system communication network, efficient and reliable transmission of transcoded fault recording data under the power system standard communication protocol was achieved, ensuring interoperability with the existing dispatching system and the standardization of data exchange.
[0054] Step S4: Configure the transcoded fault recording data through the fault information centralized management platform to generate a structured fault database.
[0055] By configuring the received transcoded fault waveform data through the centralized fault information management platform, a structured database is constructed, realizing the logical association of massive fault data, the establishment of communication channels, and the structured storage that supports multi-dimensional queries, providing an organizational foundation for efficient data analysis.
[0056] In some specific embodiments, configuring transcoded fault recording data through a centralized fault information management platform includes: S401. Data Identifier Association: Bind the transcoded fault recording data to the IP address and ID of the corresponding fault recording device; S402. Communication Link Configuration: Based on IP address and ID, establish a two-way communication link between the centralized fault information management platform and the fault recording devices of each substation; S403. Database Construction: Parse the channel configuration information in the transcoded fault recording data, and generate a structured fault database that supports multi-dimensional queries by time, substation location, and fault type based on the channel configuration information and the IP address and ID bound to the transcoded fault recording data.
[0057] By clearly defining the specific configuration steps—binding data identifiers to associated IPs and IDs, establishing bidirectional communication links based on IPs and IDs, and parsing channel configuration information to build a structured database that supports multi-dimensional queries—a strong association between data and devices, the establishment of interactive channels between the platform and devices, and the construction of flexible database query capabilities are achieved.
[0058] Step S5 involves centralized processing and analysis of the transcoded fault recording data in the structured fault database.
[0059] By centrally processing and analyzing the structured fault database, proactive monitoring, early warning, and visualization of potential faults and abnormal states in the power grid are achieved.
[0060] In some specific embodiments, centralized processing and analysis of transcoded fault recording data in the structured fault database includes: A visual monitoring interface is generated based on transcoded fault recording data from a structured fault database. Real-time monitoring of minor trigger records, including instantaneous ground fault records and phase voltage instantaneous sag records; Dynamic alarm records and early warnings of accidents are generated based on minor triggering records.
[0061] By centrally processing and analyzing data to generate a visual monitoring interface, monitor minor trigger records in real time, and generate dynamic alarm records and early warnings of potential accidents, the system has improved its ability to monitor, visualize, and warn of minor anomalies in the power grid.
[0062] In some specific embodiments, the criteria for determining a minor trigger record are: a phase voltage sag of ≥10% and a duration of ≥0.1 seconds.
[0063] By clarifying the criteria for determining minor trigger records, a quantitative identification threshold for potential power grid anomalies was set, providing a unified and operable basis for judgment for the early warning system.
[0064] In some specific embodiments, the conditions for generating dynamic alarm records are: when the duration of a single minor trigger record exceeds a set time threshold, or when the number of minor trigger records occurring in the same substation within a certain time window exceeds a set number threshold, dynamic alarm records are generated.
[0065] By setting the generation conditions for dynamic alarm records as either a single minor trigger duration exceeding a threshold or the number of times the same station exceeds a threshold within a certain time window, a combined judgment mechanism based on the frequency and duration of minor trigger records is implemented, improving the targeting and accuracy of alarms.
[0066] In some specific embodiments, the triggering condition for an accident precursor warning is: when the time interval between three consecutive minor trigger records is less than 5 minutes, an accident precursor warning is triggered.
[0067] By setting the trigger condition for accident early warning to the time interval between three consecutive minor trigger records being less than 5 minutes, the system can identify multiple abnormal event clustering patterns within a short period of time, providing earlier warning signals for potential serious accidents.
[0068] In some specific embodiments, step S5 further includes periodically performing data cleanup operations on the structured fault database, retaining only minor trigger record data in the historical data, and deleting non-trigger continuous record data.
[0069] By regularly performing data cleanup operations on the structured fault database, the database storage space was optimized, focusing on valuable event records and improving the efficiency of subsequent analysis.
[0070] In some specific embodiments, the data cleaning operation is performed every 150 days.
[0071] By explicitly setting the execution cycle of data cleaning operations to 150 days, standardized management of database maintenance frequency is achieved, striking a balance between ensuring data validity and controlling storage costs.
[0072] In one specific embodiment, the steps of the centralized management method for power system fault information include: Step S1: Real-time acquisition of fault recording data of the corresponding substations through fault recording devices installed in each substation, and allocation of a unique IP address and unique ID to each fault recording device. The fault waveform data is in the form of an ICD file or a CID file, containing logical nodes, data attributes, waveform sample values, and timestamps; The fault recording device is directly connected to the local dispatch network switch in the substation via a network cable, and the local dispatch network switch is connected to the existing dispatch communication network of the power system.
[0073] Step S2: At each substation, the fault recording data is processed for format standardization to generate transcoded fault recording data in a unified format. The transcoded fault recording data includes channel configuration information, waveform sampling values and timestamps. Format standardization processes include: S201. Import fault waveform data; S202. Parse the logical nodes and data attributes in the fault recording data to generate a device data structure mapping table; S203. Based on the equipment data structure mapping table, configure the parsing rules for fault recording data in the PCS-9700 system configured locally in the substation; S204. According to the parsing rules, the original waveform sample values and fault timestamps are converted into waveform sample values and timestamps in COMTRADE format. At the same time, the logical nodes and data attributes are mapped to channel configuration information to generate transcoded fault waveform recording data in COMTRADE format. The device data structure mapping table includes: The correspondence between signal types and logical nodes; The correspondence between sampling rate and data attributes.
[0074] Step S3: Upload the transcoded fault recording data and its corresponding IP address and ID to the regional dispatch communication network through the local dispatch network switch, and then transmit it to the fault information centralized management platform through the regional dispatch communication network. The dispatch system communication network adopts the IEC61850 communication protocol when transmitting data.
[0075] Step S4: Configure the transcoded fault recording data through the centralized fault information management platform to generate a structured fault database, including: S401. Data Identifier Association: Bind the transcoded fault recording data to the IP address and ID of the corresponding fault recording device; S402. Communication Link Configuration: Based on IP address and ID, establish a two-way communication link between the centralized fault information management platform and the fault recording devices of each substation; S403. Database Construction: Parse the channel configuration information in the transcoded fault recording data, and generate a structured fault database that supports multi-dimensional queries by time, substation location, and fault type based on the channel configuration information and the IP address and ID bound to the transcoded fault recording data.
[0076] Step S5 involves centralized processing and analysis of the transcoded fault recording data in the structured fault database, including: A visual monitoring interface is generated based on transcoded fault recording data from a structured fault database. Real-time monitoring of minor trigger records, including instantaneous ground fault records and phase voltage instantaneous sag records. The criteria for judging minor trigger records are: phase voltage sag amplitude ≥10% and duration ≥0.1 seconds; Dynamic alarm records and early warnings of accidents are generated based on minor trigger records; Regularly perform data cleanup operations on the structured fault database, retaining only minor trigger records from historical data and deleting non-trigger continuous records. The data cleanup operation is performed every 150 days. The conditions for generating dynamic alarm records are as follows: when the duration of a single minor trigger record exceeds a set time threshold, or when the number of minor trigger records occurring in the same substation within a certain time window exceeds a set number threshold, a dynamic alarm record is generated. The trigger condition for an accident warning is: when the time interval between three consecutive minor trigger records is less than 5 minutes, an accident warning is triggered.
