摘　　要：受电源分布、电网结构及负荷特性等因素影响,电网运行中存在着一些薄弱环节,这些薄弱环节成为制约电源送出及电网受电的重要瓶颈。本文分析探讨湖南电网实际运行,通过合理安排运行方式,在重要元件检修方式下通过开合环改变局部电网结构、并辅以切机切负荷等措施,提高电网输送能力,确保负荷供应。There are some weaknesses in the power grid due to the location of the power plant,structure of the power grid and the load property. These weaknesses become the bottleneck of the power transmission. This paper analyzes the power operation of hunan power grid,The transmission capacity of the power grid can be improved and the load supply can be ensured by arranging the operation mode reasonably,changing the structure of the local grid through the opening and closing ring and cutting the load with the cutting machine under the maintenance mode of the important components.
