Research on Topology Identification Method of Intelligent Terminals for High-Voltage Consumer Electrical Systems
As the grid environment is becomes increasingly complex,and the uncertainty in the operation process continues to increase,and the topology is constantly changing leading to difficulties in accurately recognizing faults.To improve the accuracy of topology identification of high-voltage consumers power supply and use systems,an intelligent terminal topology identification method for high-voltage consumers electrical systems based on intelligent terminal measurement data is proposed.The communication address of the electrical intelligent terminal is utilized to correlate the switch sub-nodes at all levels,and the electrical intelligent terminal node data is collected.According to the clustering algorithm,the parent-child relationship characteristics of the electrical energy data of each branch are determined.Innovatively,the affiliation of feeder nodes at all levels in the system is obtained through the data clustering analysis method to realize the topology identification of high-voltage consumer electrical system.The effect of topology identification is tested in three scenarios.The test results show that the method accurately recognizes three topologies under different situations in the same station area and can effectively use the measurement data to accurately identify the topology of the distribution system.
