摘要
采用基于灵敏度分析的发电重新调度方法对电力系统的小干扰稳定问题进行分析研究。研究过程中使用小干扰稳定分析工具(small signal analysis tool,SSAT)对典型运行方式下湖北电网的低频振荡模式进行分析,并对其中的鄂恩纳吉模式进行了发电机组重新调度,验证结果显示,在没有用传统阻尼控制器的情况下,使用该方法可有效提高电力系统的小干扰稳定性。
Sensitivity-based generation rescheduling method is used for researching small signal stability of power system.By use of the small signal analysis tool（SSAT）,the modes of low frequency oscillation in Hubei grid under typical oprational patterns are anlayzed,and generating units are rescheduled for the E-En Naji mode.Results show that the proposed method can significantly improve the small signal stability of power system without traditional damping controllers.
