摘　　要：本文用计算机时域分析法研究了某大型水电厂在弱联系工作状态下的持续低频振荡现象,并由计算和计算机仿真结果,提出抑制低频振荡的附加励磁控制(PSS)及附加调速器控制的参数,同时,对两者的效果作了比较。In this paper,the author used computer time-domain analysis method to study the continuous low-frequency oscillation phenomenon for hydraulic power unit of a large hydraulic power stat- ion in the state of “weak” linking to finite-bus-system,operation And the rational parameter sets of the auxiliary exciting control and the auxiliary governor control for restraining the low-frequency oscillation have been given based on the calculation and computer simulation. The effects of two auxiliary controls on the lowfrequency oscillation was provided and a comparison between them was made as well.
