【摘要】 随着电力系统规模不断扩大和快速励磁系统的引入，电力系统低频振荡问题日益突出。本文根据特征值分析法对河北南网振荡模式分类，深入研究了励磁方式对系统阻尼特性的影响，同时结合大系统固定模的概念，对振荡模式的可控可观性进行了分析。所得结论对于电力系统低频振荡抑制以及电力系统稳定运行具有重要的参考价值。更多还原

【Abstract】 With the continuous spreading of scale in power system and introducing of fast exciter system, the problem of low frequency oscillation becomes worse and worse By means of eigen-analysis, this paper classified the oscillation modes based on South Hebei power system and presented the careful research for the influence of exciter type to damping characteristic0 At the same time, the concept of fixed modes is used to analyze the controllability and observability of oscillation mode The conclusions provide the important reference for the suppression of low frequency oscillation and stable operation in power system 0Li Lingzhi (Power System and its Automation)Directed by Prof. Pan Yunjiang and Zhao Shuqiang更多还原
