| Abstract: | Based on the analysis of the problems of starting element commonly used in high voltage transmission line protection. according to different characters in different operating state.several operation state discrimination criterions arc developed. Analysis and simulation results show that the crilerions can discriminate power swing from short circuit and also detect whether the relay is closed on a normal line or a fault line during manual closure and auto-reclosure. |

| Keywords: | power system protection starting element power swing auto and manual closure harmonic terms |
