摘　　要：本文从小机组对220kV主网动态稳定性影响的角度,对基于小机组详细模型的2006年安徽电网进行了小干扰稳定性深入研究,具体采用频域法及PSD-SSAP程序对全系统的特征根进行仿真,分析安徽电网加入地区电网小机组后的阻尼特性,找出动态稳定的薄弱环节,用时域曲线仿真计算校核时域计算结果,并对全网弱阻尼特性机组提出改善与控制措施。This paper presents an analysis of the small perturbation stability of the AnHui power grid based on the detailed excitation model of the small-load generators. To find the weakness of the grid dynamic stability, all the eigenvectors of the system are calculated by the PSD-SSAP software and the frequency-domain method, then the damping characteristic of the AnHui grid is analyzed considering the small-load generators. The result is verified by simulation.
