摘　　要：结合电网的实际运行情况及国内外停电事故的经验教训,确定了华东电网预想故障集,并对故障集进行了仿真分析。根据仿真结果,总结了2012年华东电网潜在的失稳模式及所需要的解决方案,并基于无功功率的原理对各个潜在失稳模式下的失步中心进行研究分析,确定了在各个失稳模式下的失步解列断面,为华东电网制定失步解列控制策略提供依据。Combining with the actual operation of power grid and the lessons of blackouts, the anticipated fault sets of East China gird are determined, and the fault sets are simulated in the paper. Based on the simulation results, the potential unstable modes and the solutions of East China grid are summarized. The center of out-of-step under each potential unstable mode is analyzed based on the principle of reactive power, separation interface under each unstable mode is determined, which provides the basis for the separation control of East China gird.
