Abstract

Abstract: A multi-agent units-based coordinated protection method is proposed based on analyzing the methods for realizing hierarchical regional protection of power system. The fault information of each measurement point’s agent unit is firstly optimized by Kalman filter, and then the fault direction information and the fault correlation matrix can be obtained. Finally, the fault location can be determined according to the correlation matrix and the criterion. Numerous theoretical analysis and simulation results show that such method can effectively locate the fault components. This regional protective system can match with the traditional point protection and solve the override trip problem in the power supply system.

Key words: regional protection system, multi-agent units, Kalman filtering, fault correlation matrix, override trip
