Study on identificaiton of permanent fault for transmission lines with shunt reactors
Author(s): 
Pages: 43-46
Year: Issue:  18
Journal: POWER SYSTEM PROTECTION AND CONTROL

Keyword:  继电保护输电线路并联电抗器自适应重合闸;
Abstract: 以瞬时性故障模型为参考模型,根据已知量求取并联电抗器故障相电流,利用该求取电流与并联电抗器故障相实际测量电流之差同中性点小电抗器电流幅值比来实现永久性故障的判别.通过利用 ATP 仿真验证和西北电网 330kV 系统的故障数据验证,结果表明该方法可准确判别瞬时和永久性故障.
