Research On Mode Analysis And Damping Characteristic Of Low Frequency Oscillation In Power Syatem

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...
