| Abstract: | In this paper, the protection principle based on current rate of change is introduced, and a kind of filtering algorithm is deduced by mathematics. By this algorithm, the AC harmonic components of short-circuit current can be filtered, and the accurate DC current rate of change can be obtained. The simulation result shows the effectiveness of the filtering algorithm. |
