摘　　要：提出了一种电力系统低频振荡起振原因分析方法。该方法应用电力系统小干扰稳定性分析软件PSD-SSAP和潮流及暂态稳定程序PSD-BPA,结合广域测量系统(wide area measurement system,WAMS)低频振荡实测结果,从静态稳定性分析和事故仿真角度对功率波动和低频振荡的发生环境、起振原因进行分析。分别对区域内与区域间低频振荡进行了仿真研究,仿真结果验证了该方法的有效性。A method is proposed for analyzing the causes for low frequency oscillation of power system.Based on the application of the PSD-SSAP power system small signal stability analysis software,the PSD-BPA power flow and transient stability program and combined with the WAMS low frequency oscillation measured results,this method can make an analysis of the environment and oscillation causes for power fluctuation and low frequency oscillation through static stability analysis and fault simulation.
