Abstract Because of the characteristics of the interference in Power system and the Ports of Power system automation equipments, developing EMI filters applied to Power automation equipments .A new kind of EMI filter design method, which adopted Matlab-GUI, It’s a simple algorithm with real-time response. This detection method was fit for the single-phase and three -phase different topology filters. The filer was designed according to simulation result which compare the current interference which used or not. The result shows that it is good to adapting this method.
