摘要
近年来世界范围内发生的多起电压失稳事件使电压稳定问题受到更多关注。对江西电网的电压稳定状况进行了评估,介绍了用于求取电压稳定极限的延拓算法,并采用该方法计算了江西电网2007夏季大方式下的电压稳定裕度,电网的电压稳定关键节点及电压稳定薄弱区域研究采用雅可比矩阵的模态分析法,对江西电网的电压稳定分析结果为江西电网的安全稳定运行提供了有意义的指导。
In recent years, much attention has been attracted to the problems of voltage stability in power systems. The operation status about voltage stability in Jiangxi power system was evaluated. The continuation algorithm was introduced first to acquire the voltage stability limit using the 2007 summer data of Jiangxi power system. The key node and the weak area of voltage stability were studied using Jaeobian matrix modal analysis method. The results of the research provide the reference to the safe and stable operation of Jiangxi power system.
