Power system relay protection simulation based on MATLAB

Jie Yang and Qiufeng Yao

Abstract

MATLAB -based simulation technology can support the analysis and design of relay protection systems. A simulation model is built for the study of power system relay protection. As an example, the power system fault simulation, zero-sequence current protection simulation and transformer differential protection simulation are presented herein. The case studies show that the simulation of power system relay protection is effective and feasible.
