AI Technical Summary
In existing technologies, the efficiency of extracting action event information of relay protection devices is low, the data silo problem leads to long fault diagnosis time, and there is a lack of automatic association of multi-source data and standardized equipment matching benchmarks, making it difficult to support rapid fault analysis and operation and maintenance management of power systems.
Based on trip records, a globally standardized equipment knowledge base is constructed. A two-dimensional precise matching technology is adopted to achieve accurate correlation of data from the SCADA system, the information protection substation, and the fault recording system. Through automatic fusion of multi-source data, event information is automatically obtained and an accident analysis report is generated.
It reduces fault diagnosis time from over 4 hours to minutes, improves data matching accuracy, reduces manual verification costs, supports automatic matching and manual correction, and forms a closed loop of complete event extraction and accident judgment, meeting the rapid operation and maintenance needs of power systems.
