【摘要】 在电力系统网络暂态能量函数的基础上，分析网络中暂态能量分布与系统稳定性的关系。通过对网络中输电瓶颈（割集）的暂态能量变化特点的讨论，提出系统在发生瞬时性故障情况下重合闸最佳时间的整定方法。该方法能自动适应电力系统运行方式和故障方式的改变，在线整定最佳重合同时刻，改善重合闸后系统的暂态稳定水平。更多还原

【Abstract】 This paper discusses the relationship relationship betwoee the transient stability and the transient energy distributed over thepower network based on the network transient energy’ function. The adaptive setting on reclosing time is presented accordingto the analysis on transient energy across transmission bottleneck in the network. This method enables setting optimalreclosing time on line corresponding to the up-to date power system operating operating and fault states for improving powersystem transient stability.更多还原
