摘　　要：多回输电线路共用通道发生故障时需要考虑整个通道N-1对电网带来的冲击及影响,本文对不同线路故障引起的多回输电线路共用通道N-1引起的电网故障运行风险进行研究,对电网各项工程实施前后不同网架下的同一处多回输电线路共用通道各种组合进行分析和总结,并针对当前项目中存在的问题和不足提出相关建议。When the shared channel of multi-circuit transmission lines fails,it is necessary to consider the impact and influence of the whole channel N-1 on the power grid.In this paper,the operation risk of power grid failure caused by the shared channel N-1 of multi-circuit transmission lines caused by different line failures is studied,and various combinations of shared channels of the same multi-circuit transmission lines under different grids before and after the implementation of various power grid projects are analyzed and summarized.And discuss the existing problems and shortcomings in the current project,and give relevant suggestions。
