针对 2 0 0 2年 7月 15日 5 0 0kV漫昆I回线路发生C相瞬时性接地故障 ,漫湾侧TLS - 1B高频距离保护在非全相过程中发生三跳的动作行为进行仿真试验及分析 ,并阐明漫侧TLS - 1B高频距离保护在非全相过程中异常动作行为的原因。
In order to simulate the three-hop instantaneous ground fault occurred on the 500kV Man-Kun I line and the TLS-1B high-frequency distance protection on the Manchuian side on July 15, 2002, Test and analysis, and elucidate the reasons for the abnormal behavior of diffuse TLS - 1B high frequency distance protection in nonphase processes.
