Topology Identification Method for Electric System of High-voltage Customer Based on Electric Intelligent Terminal Measurements

Abstract

Aiming at the low degree of automation in the identification of the topology structure of the high-voltage customer power supply and consumption system, this paper proposes a topology identification method of the high-voltage customer power supply and consumption system based on the measurement data of the intelligent terminal. The communication address of the electrical intelligent terminal (EIT) is used to correlate the switch sub-nodes at all levels, and the topological relationship between the upper and lower levels of each branch is determined, and then the subordination relationship of each level in the platform system is obtained through a large amount of data clustering analysis method. The simulation results of the example system show that the method can effectively utilize the redundancy of measurement data and accurately identify the topology of the power distribution system.
