摘　　要：由于以电功率信号为单输入的传统PSS存在严重的无功反调现象,该文研究了加速功率型PSS在抽水蓄能机组中的应用及其参数整定方法,分别在发电和抽水工况下,以及工况转换过程中,对附加PSS前后的系统响应进行了仿真及对比分析,结果表明该方法的正确性和有效性。加速功率型PSS在提供良好的阻尼的同时,可以有效地抑制无功反调。The traditional PSS with electric power as single input signal has serious reactive power antiregulation problem, so the parameter setting method of PSS based on PSS2A model of IEEE is studied when it is applied to pumped storage units. The system responses are simulated respectively in generation and pumping conditions, as well as the conversion progress of working condition and the results before and after installing PSS are compared, it proves that the method is valid. PSS based on PSS2A model of IEEE can efficiently restrain the atiregulation problem while providing good damping effect.
