| Abstract: | By using the Simulink toolbox of the MATLAB, the article simulates on the short-circuit fault of the electric power system and analyzes the single-phase current pilot differential relay operating characteristics. The simulation results show that the segregated current pilot differential protection is absolutely selective and highly sensitive in judging the short-circuit fault. |
