摘要
分析了220kV终端变的220kV保护配置方案。提出220kV终端变的220kV线路保护配置单套光纤纵差保护;针对终端变对侧的220kV旁路保护代线路光纤纵差保护的情况,给出了两种旁路保护配置方案;并提出了终端变的220kV失灵保护应按断路器配置。
The scheme of 220 kV relay protection about 220 kV terminal substation is analyzed. Single optical-fiber longitudinal differential protection is adopted as 220 kV line protection. When 220 kV bypass protection takes the place of optical-fiber longitudinal differential line protection in offside substation, two kinds of arrangements are provided. 220kV malfunction protection should be configured according to circuit breaker.
