基于暂态量超高压输电线路无通信保护的研究

高压输电线路发生故障后的暂态电压或电流分量中含比工频分量更多的故障信息，充分利用这一信息是构成具有绝对选择性单端无通信保护的前提，对目前基于暂态量的无通信保护的研究进行了对比和分析，并提出了目前基于暂态量的高压线路无通信保护的发展方向。

Superpressure Power Transmission Line Non-Communication Protection Based on Transient Component

During the fault period,transient component of fault current or voltage which consists of large amount of high frequency components is mainly due to the current travelling wave and nonlinear arc fault resistance at fault position.Moreover,it is the basis of constructing a new non communication protection through absolutely utilizing the fault information which is comprised in transient component of fault current or voltage.This paper explains all principles of transient protection and directs the way of non communication protection development.
