一类含异步风电机组的电力系统小干扰区间稳定性分析
Interval Stability Analysis of Small Signal for a Class of Power System With Asynchronous Wind Turbine Generators
摘要
Abstract
Based on the small signal stability model of asynchronous wind turbine, which include the dynamic characteristics of turbine, shaft and generator, an asynchronous wind turbine model with interval parameters was built and the small signal stability of this model was analyzed in theory. In this model, uncertain parameters which vary in certain ranges were considered. By constructing Lyapunov function, applying matrix theory and other methods, the stability theorem of asynchronous wind turbine model with interval parameters was proved, which shows that the stability of the power system can be determined by the ranges of system operating parameters. Finally the method was tested by the numerical simulation, and the result shows that it is effective and practical.关键词
