| Abstract: | Through analyzing and comparing several algorithm methods of distance relay protection,the fourier algorithm is selected.The influence on the distance relay protection in EHV electric power system caused by the transient respond characteristics of CVT is studied by means of the digital simulation. The purpose is to help the persons who deal with the relay protection in electric power system,so as to focus on the study of algorithms of relay protection to find solutions,and to reduce the influence of the transient respond characteristics of CVT on the relay protection as far as possible. |
