摘　　要：提出在发电机PSS现场试验时,通过人为设置扰动事件来激发电网区域振荡模式以验证发电机PSS对低频区域振荡模式的阻尼效果,并基于精细时域仿真软件PSCAD/EMTDC,建立云南电网PSS阻尼效果仿真系统模型,通过设置扰动事件进行仿真计算,验证发电机PSS对低频区域振荡模式具有正阻尼效果,弥补了现场试验的不足。A concept is proposed in this paper, that is： during the side experiment of generator＇s PSS, to stir up the area oscillation by a artificial disturbance, therefore to verificate the positive damping effect given by the generator＇s PSS, Based on the PSCAD/EMTDC software, simulation model of PSS demping effect of Yunnan Power Grid is built. The calculation result on disturbance proved the positive damping effect given by the generator＇s PSS, therefore to make up the insufficiency of side experiment.
