摘要

针对带并联电抗器的超高压线路，分析了故障跳开相恢复电压公式，详细推导了故障跳开相恢复电压的工频分量幅值、自由分量幅值及自由分量频率，理论分析及EMTDC仿真实验证明了推导结果的正确性，基于此提出采用恢复电压的拍频特性作为无故障判据，该无故障识别方法具有很强的实用性，为带并联电抗器输电线路采用单相自适应重合闸提供了一种非常简单可靠的方案。

Abstract

This paper analyzes the voltage characteristics of the faulted phase for EHV transmission lines with shunt reactor， as well as the power frequency component， low frequency component， and the frequency of free component. A new criterion using the beat frequency characteristics is proposed， which can distinguish the temporary faults from permanent faults perfectly. Theoretical analysis and EMTDC simulation tests show that this novel criterion is correct and practical， which provides a simple and reliable method for the realization of single-pole adaptive reclosure.
