摘　　要：本文就电气整套启动试验中发变组短路试验提出了改进方法,即在发变组短路试验中,利用各微机自动装置的采样进行电流回路的幅值相序检查,通过检测各自动装置无功测量的结果来判断方向性保护的正确性。This paper proposes improvement method on the short-circuit test of generator-transformer unit in the test of electric wholeunit start-up. namely, uses the sampling by the automatic device of every microcomputer to carry out amplitude, phase sequence inspection of current circuit, and judges the correctness of directional protection by testing the result of reactive power measurement of every automatic device in the short-circuit test of generator-transformer unit.
