摘要 以非线性分岔分析软件Auto97为工具,以一个标准的三节点系统为对象,研究了发电机阻尼模型和参数扰动对电力系统小扰动稳定性和系统分岔的影响。研究发现,在采用不同的阻尼模型时,会导致不同的系统分岔形式和不同的混沌现象出现区域;为此求解了在关键参数扰动下系统的受扰稳定域,并分析了稳定域的边界特性。 Using the bifurcation analysis software Auto97 and aiming at a standard three-bus power system, the influence of generator damping models and parameter fluctuation on small signal stability and bifurcation of power system is analyzed. It is found that different damping models will lead to different system bifurcation modes and distinct chaos regions. Therefore the disturbed stability region of system under the fluctuation of key parameters is solved, and the boundary characteristic of the stability region is analyzed.
