摘　　要：在电力系统网络暂态能量函数的基础上,根据暂态能量在网络中的分布与系统稳定性之间的关系和对包含故障线路的脆弱割集分布的暂态能量的分析,提出了永久性故障最佳重合闸时间的自适应整定方法。对多机系统的仿真表明,用此方法可有效阻尼重合闸后对系统的摇摆,改善哲态稳定水平。On the basis of network transient energy function, the relationship between the distribution of transient energy in network and system stability,and analysis of transient energy including vulnerable cutset distribution over fault circuitry after fault clearing, the adaptive setting method on reclosing time of permanent fault was proposed in this paper. The vibration after reclosing time could be damped effectively in the simulation of multimachine system. The stability of system transient state also could be improved.

关 键 词：最佳重合闸时间 暂态稳定 网络暂态能量 割集
