摘　　要：采用阻尼分析方法,在分析加速功率型电力系统稳定器(PSS)工作原理的基础上,阐述了PSS输入状态量的含义及其作用。分析了电网运行方式或电网结构变化对PSS工作特性的影响,提出了目前加速功率型PSS中不宜采用发电机组机端电压频率信号代替发电机组转速信号的观点。The operation principle of an improved rotational speed power system stabilizer （PSS） is analyzed with the power system damping analysis method. The concept and function of PSS input state variables are detailed, as is the effect of the operational mode and grid structure on PSS working performance. It is concluded that it is currently inadvisable to replace the generator rotational speed signal with the terminal voltage frequency signal as the PSS input state variable.
