摘　　要：基于DIgSILENT/PowerFactory模态分析功能,得出了发生机电振荡时局部和区域模态各电机参与因子的模态柱状图、向量图,以辨识PSS最佳安装位置。通过特征值分析和时域仿真,验证了系统安装PSS后的稳定性,对复杂系统PSS安装地址的选取至关重要。The vector diagram and bar plot of the generator participation factor of local mode and inter area mode were put forward based on DIgSILENT/PowerFactory, when the power system occurs electromechanical oscillations. The PSS optimum position was pointed out. Through eigenvalue analysis and time-domain simulation, the system stability was identified. It is important for PSS installing address selection in complex systems.
