摘　　要：对华东电网主要区域间振荡模式、浙江电网主要区域内低频振荡模式进行了仿真分析,并着重围绕浙江机组的参与特性展开研究。研究了主要机组PSS的投退、以及浙江电网不同运行方式对华东电网主要区域间振荡模式及浙江电网主要区域内振荡模式的影响,指出2010年各相关电厂应充分重视机组励磁系统及PSS实测建模、PSS整定和投入工作。The main interregional oscillation modes of East China Power Grid and the main regional low frequency oscillation modes of Zhejiang Power Grid were simulated and analyzed in this paper.The participation characteristics of Zhejiang power plants were investigated.The impacts of different operation modes of Zhejiang Power Gird as well as the exiting of PSS on the above main low frequency oscillation modes were analyzed.Conclusions were drawn that the related power plants should pay attention to the unit excitation system,the measuring data based PSS modeling,and the setting and input operating of PSS.
