摘　　要：本文提出了一种新的故障检测方法，并与目前使用的检测单相电流突变量和相电流差突变量的方法进行了比较。文中还提出利用同一故障检测量实现故障选相，经过大量的动模实验表明所述方法具有一系列优点。A new fault-detection method is proposed in this paper.The newly developed method is compared with the existing ones,whose successful operation depend on checking the surge in single-phase current and phase to phase current difference.Also in this paper presented a new way of phase-select for faults through fault checking measurements.Dynamic model test`s results show that the proposed method has a series of advantages.
