220kV长距离联络线降损方案研究及验证

Investigation and Verification of Loss Reduction Scheme for 220kV Long-distance Interconnection Line

以秦皇岛220 kV长距离联络线降损方案为实例,简要对比几种联络线线损率,得出与唐山220 kV电磁环网的解环运行方式将最有利于降低线路率,以期为类似长距离联络线降损方案提供借鉴。

Taking the scheme of reducing loss of Qinhuangdao 220kV long-distance interconnection line for example,the line loss rates of several types of interconnection lines were compared briefly.It was concluded that the operation mode of uncoupling the loop with Tangshan 220 kV electromagnetic loop network was the most advantageous to reducing the line loss rate,which was expected to provide references for the loss reduction scheme of similar long-distance interconnection lines.
