摘　　要：基于网络拓扑结构,根据系统失稳时暂态能量在网络中的分布变化特性以及支路两端相角差的变化特点,提出了利用支路两端相角差作为失步解列原理的判据,并对失步解列装置在电力系统中的布点及解列点的选取进行了探索性的分析,指出解列点的选取不应仅以平息振荡为原则,还应保证尽量增强解列后系统的自恢复能力。对新英格兰10机系统进行仿真分析,验证了所提方法的有效性。Based on topological structure of network, according to distribution feature of transient energy in network and the change feature of branch phase angle difference, the criterion using branch phase angle difference was proposed, the distribution of out-of-step separation device in power system and the selection of out-of-step separation location were investigated. The rational selection of out-of-step separation location should not only suppress oscillation, but also strengthen self-restoring capability of power system. The simulation on NEW ENGLAND 10 machines testifies the validation of the proposed method.
