摘　　要：根据输电线路电磁行波的暂态表示形式,考虑线路分布参数影响和电磁行波特点,建立线路分布参数模型,考虑电磁行波在该模型中的波动特点,提出复域中的行波分析方法,并通过推导证明,发生短路故障时,该模型可以计算线路各点电压分布,从而定位故障点。According to the representation of electromagnetic traveling wave,in consideration of the distributed distributed-parameter effect and electromagnetic traveling wave features,a distributed-parameter model is thus built up.Considering the features of the electromagnetic traveling wave in the model,traveling wave analysis method is proposed for the complex domain.And by derivation and demonstration,when short-circuits occurred,the model can calculated out the voltage distribution of the transmission line to locate the fault points.

关 键 词：电磁行波 分布参数 投影变换 正交尺度
