摘要
故障行波技术已经广泛应用于输电网中,然而不同电力设备在行波传变过程中存在着明显的差异,因此有必要研究电力设备传变故障行波信号的特性。首先分析了变电站故障行波的构成,然后分析了故障行波在典型变电站设备中的传变特性,最后分析了变电站不同电力元件处对行波信号的影响,揭示了电力设备传变故障行波信号的本质。
The fault traveling wave technology has been widely used in the transmission network.However,there are obvious differences in the traveling wave transmission process of different power equipment.Therefore,it is necessary to study the characteristics of the power equipment transmission fault traveling wave signal.This paper first analyzes the composition of fault traveling waves in substation,and then analyzes the transmission characteristics of fault traveling waves in typical substation equipment.Finally,the influence of different power components in the substation on the traveling wave signal is analyzed,and the essence of the traveling wave signal of the power equipment transmission fault is revealed.
