摘　　要：针对山西电网神雁双回线路故障后安全稳定控制量过大可能引起大同电网和山西主网解列的问题,对影响安全稳定控制量的敏感因素进行详细分析,包括故障形式、故障清除时间、安全稳定控制量动作时间、切机方案、电压水平等因素,为山西电网优化安全稳定控制量措施提供技术参考,保证电网安全稳定运行。Excessive security and stability controlling margin on Shanxi power grid Shenyan double circuit line may lead to splitting accident in Datong power grid and Shanxi main grid. In this paper,sensitive factors affecting the security and stability controlling margin are analysed,including failure mode, the fault clearing time, the action time for security control,generator tripping scheme,and voltage level etc.. The conclusion provides reference for optimizing the margin controlling scheme in Shanxi power grid,and ensures the safe and stable operation of the power grid.
