探索综合利用故障初始电流、电压行波线模分量实现配电线路双端故障测距的新方法。
A new method of fault location for distribution feeders based on the aerial mode component of fault generating current and voltage traveling waves is discussed.
该文提出利用线路故障产生的暂态行波实现配电架空线、电缆混合线路单相接地及相间短路故障测距，分析了故障初始行波模分量的暂态特征。
Using transient traveling waves generated by fault to locate single-phase earth fault or short circuit fault in distribution feeders mixed with overhead lines and cables is proposed.
此外，故障电压行波于非对称短路点发生线模与零模行波相互交叉透射，致使故障电压自然频率“混叠”。
In addition, line mode and zero-mode voltage wave cross each other at the point of fault which causes the natural frequency "aliasing".
