摘　　要：分析了励磁调节器励磁调节不当引起电力系统产生低频振荡的原因,然后阐述了电力系统稳定器(PSS)抑制低频振荡的原理;介绍了某水轮发电机组PSS参数试验步骤,验证PSS抑制低频振荡的效果,进而证实了PSS参数整定的正确性。The reason of low frequency oscillation in power system caused by improper excitation regulation is analyzed,then the principle of power system stabilizer（ PSS） to suppress low frequency oscillation is described; In this paper,the test procedure of PSS parameters for a hydroelectric generating set is introduced and the effect of PSS to suppress the low frequency oscillation is verified,which confirms the correctness of PSS parameter setting.
