220 kV及以上电网一次设备的复杂故障分析及处理研究
|
摘要
从资料收集、初始分析、特征量、过程分析、现场检查验证等方面介绍了复杂故障分析的过程,详细分析了两种常见复杂故障即同杆双回线同时故障和交叉区域故障时的特征,并通过实际案例波形进行说明,该特征量分析能快速准确对故障定位,为复杂故障整体分析提供很好的参考。
The process of complex fault analysis is introduced from the aspects of data collection, initial analysis, characteristic quantity, process analysis, on-site inspection and verification. The characteristics of two kinds of common complex faults namely simultaneous fault of double circuit lines on the same pole and fault of intersection area are analyzed in detail, which is explained through actual case waveform. This characteristic analysis can quickly and accurately locate faults and provide a good reference for the overall analysis of complex fault.
