关于安鹤濮220kV电网安全稳定风险评估的研究

针对500／220kV电磁环网解环前的豫北电网（2007年-2008年），从供电负荷、网架结构、电网稳定性等方面对安鹤濮电网存在的问题进行分析，并尝试分析母线故障、开关失灵等“N-（1＋1）”严重故障对电网的影响，校核电网的安全稳定性，分析电网发生稳定破坏、电网解列、大面积停电等重大电网事故的关键环节和重要变电站、线路。为电网运行风险控制提供参考。

Research on the Risk Evaluation of Safety and Stabilization about AnHePu's 220kV Power Network

In year 2007 or 2008,electromagnetic loop circuits of the north power network of Henan will not be opened,this paper try to find some problems by researching on loads,power network structure;then try to study the infection of some serious faults,for example,the bus fault,the switch malfunction,or N-(1+1) faults,and so on;and check against network's safety and stability.By the study,we can find out the key points and important substations and lines. Some useful references can be provided also.
