摘　　要：随着电网规模的不断扩大,电力系统低频振荡问题目益突出。电力系统稳定器(PSS)是抑制振荡,增强电力系统稳定性的重要措施。它通过把相关信号传递到电压调节器来抑制机组之间的低频振荡。PSS的设计方法、参数调整的优劣直接影响到其功能有效性。分别从研究和工程的角度进行了介绍,研究角度从参数选择、选址问题和鲁棒性方面介绍了PSS的基本问题,而后交代了工程中参数整定的基本方法。最后对PSS的未来发展进行了展望,认为系统运行工况、多频段PSS设计和广域测量方法等方面还需更进一步研究。With continuous expansion of power grid,low-frequency oscillation in power system is increasingly serious.Power system stabilizer （PSS）,which can suppress low frequency oscillations by transferring related signals to voltage regulator,is widely accepted as an effective method for restraining the low frequency oscillations and improving the stability of power system.The validity of its function depends on the design method and parameters adjustment of the PSS.The paper gives an introduction from the aspects of both research and engineering respectively.The parameter selection,site selection and robustness is studied as basic problems of the PSS,and basic parameter setting methods in engineering are mentioned.Finally,the paper discusses the development prospect of the PSS,and also shows the necessity to further study the system operation condition,the design of multiband PSS and wide-area measurement methods.
