高压长线的分布参数模型与测量阻抗

Distributed Paramefer Model of Long-UHV-Power-Line and Detected Impedance

本文介绍了分布参数的数学模型计算高压长线故障的方法。并以线路单相故障为例进行故障计算、探讨了接地阻抗继电器感受的阻抗和负荷状况。

?This paper introduces the fault calculation method of long-UHV-power line by distributed parameter model.As an exemplar,the paper discussed relay's detected impedance and effections of load current,grounding resistance under one-line-to-ground fault condition.
