摘要
为了揭示故障行波在故障点的产生及折、反射规律,给出了一种故障行波通用分析方法。该方法将故障附加状态网络分解为正常运行系统侧输电线路和故障点新增的故障支路。根据该方法,在故障点新增的故障支路上的电流决定着电流行波在故障点的产生和折、反射;若故障点新增的故障支路是不对称接地的,零模分量和线模分量是相互转换的。
In order to explode the rules of fault traveling wave ’s generation,refraction and reflection at fault point,a universal method to analyze fault traveling wave is proposed. It decomposes additional fault state network into normal system transmission lines and fault point new fault branch. The current in new additional fault branch at the fault point determined how the current traveling waves generate,refract and reflect at the fault point. If the fault point in the new fault branch is asymmetrical and grounded,zero mode component and aerial mode component are interconverted.
