摘　　要：基于灰色关联度理论,提出了将灰色关联分析用于判断输电线的故障类型。把各种故障类型与RTDS的真实故障波形运用灰色关联度进行分析,运用实例验证了该方法评判输电线故障类型的正确性、可行性。Based on the principle of grey relational analysis, the application of judging the fault type of transmission line is proposed. With the grey relational analysis of actual fault data from all kinds of fault types and RTDS, the type of fault-phase is obtained. And the test demonstrates that the proposed method is reliable and feasible.
