摘要
随着电力工业的迅猛发展,电力系统的规模越来越大,在获得更高的可靠性和经济性的同时,大型互联电力系统的低频振荡严重危及了系统的安全运行。该文简要介绍了电力系统低频振荡的产生机理和常用分析方法,也给出了低频振荡的抑制措施,并指出了未来的发展方向。
As the rapid development of power industry, the scale of the power system becomes larger and larger. Thus, it should be more reliable and economical. At the same time, the low frequency oscillation of large-scale inter-area system has badly endangered the secure operation of the system. This paper briefly presents the causes and analysis methods of low frequency oscillations in power system, and its restraining measures. The direction of future development is predicted.
