摘要
分析了低频振荡产生的原因以及电力系统稳定器（PSS）对低频振荡的抑制作用。利用Matlab对PSS的参数进行整定，并建立了励磁调节系统仿真模型。用3种运行方式验证电力系统稳定器抑制低频振荡的能力。仿真结果表明：整定后的电力系统稳定器对低频振荡具有良好的抑制作用。
The paper analysed the causes of low - frequency oscillations, as well as the inhibitory action of the power system stabilizer （PSS） to low -frequency oscillations. We use Matlab to optimize the parameters of PSS and to establish the simulation model of excitation governor system. We verify the ability of the power system stabilizer to suppress low - frequency oscillations in three modes . The simuliation results illustrated that the PSS with the settings has good inhibitory action to low - frequency oscillations.
