摘要
近期深圳地区500 kV鲲鹏变电站500 kV线路完成了保护改造,将根据500kV岭鲲甲线保护改造的实际情况,对500kV线路保护的配置以及500 kV线路保护光纤通道的配合进行分析,并且对几种远跳方式进行了比较。改造后,线路跨线故障时保护能正确选相,保护信号通过光纤通道能更可靠快速地传输,为500 kV线路更加安全稳定运行提供保障。
Kunpeng 500kV substation in Shenzhen has completed protection transformation of 500kV line recently, according to the actual situation of 500kV Ling-Kun Line A, this paper analyses about the protection configuration of 500kV line and cooperation of optic fiber channel, and compares several ways of remote trip. After transformation, line protection can select phase correctly when cross country fault occurs, the transmission of protection signals can be more reliable and rapid in optic fiber channel, to provide more safe and stable operation for 500kV power line.
