【Abstract】 The power system stabilizer( PSS) was the most effective method to suppress the low frequency oscillation. This paper studied the domestic and international relevant achievements and its application of PSS in regional system application and reviews the PSS,including analyzing the working principle of PSS,modeling of power system,the disposition of regional PSS,time delay and the processing,PSS controller design,etc. It analyzed the basic principle of PSS based on single-machine infinite system. In the field of system modeling,it pointed that the Prony method analysis was the most frequent method of measuring analysis methods. In the disposition of regional PSS,geometric method worked better than residue method on controller placement and feedback signal selection. It also stated that phase compensation method was the most commonly used method about the processing of time delay and the PSS should have the characteristics of high degree of adaptive to meet the needs of controller about the design of PSS. In addition,the paper summarized the research directions of regional PSS,and put forward some research topics of PSS in the future.更多还原
