摘要
随着电力系统的迅速发展以及互联规模的急剧扩大,电力系统低频振荡问题已成为影响其动态稳定性以及远距离传送容量的重要因素,对趋于运行极限状态的电力系统尤其如此。鉴于此,文章综述了目前低频振荡的各类分析方法以及抑制策略,通过对比及分析阐明了各种分析方法及抑制策略的优缺点,并进一步对未来研究方向作了探讨。
As power systems developing rapidly and being interconnected in a great scale, the issue of low frequency oscillation （LFO） of the power system becomes very important for the dynamic stability and long-distance-transmission capability of the system, especially to that operating in an unprecedentedly critical state. In this paper, an overview on the analysis and control of LFO is presented with a comparison of the advantages and shortcomings of various analytic techniques and control strategies, and a perspective on LFO research.
