摘要
为了提升输电线路故障原因的自主识别能力,提出了一种基于故障行波特征的输电线路故障原因辨识方法。该方法通过分析分布式监测装置采集到的线路故障暂态行波电流,获取雷击、非雷击故障行波特征,建立了线路雷击、非雷击故障与故障行波波形的匹配关系,为输电线路故障原因的自主诊断提供了依据。
In order to improve the fault reason self-identification capability of transmission lines, a fault reason identification method of transmission lines is proposed based on the fault traveling wave characteristics. In this method, the traveling wave characteristics of the lightning faults and the non-lightning faults are obtained by analyzing the fault transient traveling wave currents of lines collected by distributed monitoring devices and the matching relation between the fault traveling wave and the lightning fault or the non-lightning fault, so as to provide a basis for the fault reason self-diagnosis of transmission lines.
