摘　　要：对同走廊线路,若同一断面多回线路同时发生故障跳闸,将对整个电网的稳定运行造成极大的影响。本文对架空输电线路常见隐患进行了统计分类,针对不同风险隐患类型给出了同走廊多回线路的定义,利用三维GIS数据库和现场调研等方式,对南方电网500kV及以上交直流输电线路同走廊现状进行了研究分析,为风险管控和运行维护提供基础数据。For the transmission lines in common corridor,it could have a bigger impact on the stability of the power grid if multi-circuit lines in the same section trip at the same time.The classification and statistics of common hidden hazard are carried out,and also the definition of multi-circuit transmission lines in common corridor is proposed for different kinds of hidden hazard. The status of multi-circuit transmission Lines of China Southern Power Grid is researched by use of three-dimensional GIS database and field investigation.The detailed distribution of multi-circuit transmission lines in common corridor of China Southern Power Grid is obtained,which can provide guidance to risk control,operating and maintenance.
