摘　　要：本文论述了华中电网在线安全稳定分析系统的基本原理和机制,在线实时态实时发现电网运行薄弱点和风险并给出辅助控制策略,在线研究态可进行预想方式和应急状态分析评估,提前拟定电网控制策略,能大幅提高电网安全运行水平和降低大范围停电风险。以特高压线路为实例进行了详细分析探讨,验证了在线分析系统功能,为调控人员掌控大电网运行提供了深入研究手段。This article discusses the basic principles and mechanisms of the online security and stability analysis system of Central China Power Grid,finds weak points and risks of grid operation online, and gives the auxiliary control strategy.The expected grid mode and emergency state can also be analyzed and evaluated in the online research mode.And the control strategies can be prepared in advance at the same time.The system improves the ability of the grid safe operation and reduces the risk of large-scale power outages greatly.As example,the UHV lines are analyzed and discussed in detail. The features of the system are verified,which provided the in-depth research tools for the dispatching and control of the power grid.
