摘　　要：利用某一高压故障选相算法进行EMTP计算机离线仿真,通过各种故障情况和4种过渡电阻状态的仿真验证了该故障选相算法的正确,满足理想选相的要求。最后通过电力系统实际运行时发生的故障数据检验算法,验证了该算法的实用性。EMTP off-line simulation is conducted by using certain HV fault phase selection algorithm. The correctness of the fault phase selection algorithm is verified through the simulation of different fault and 4 kinds of transitional resistance states. At last, the practicability of algorithm is verified through data check algorithm of fault occurred in the real operation of power system.
