首先针对恒速异步风机和双馈变速风机的物理结构建立了数学模型,通过电力系统分析工具箱PSAT软件,建立了两机——无穷大的系统仿真模型;然后对含风电场并网的电力网络中,发生相同扰动后系统的动态响应行为进行了仿真对比,发现随着风电场并网容量的增加,风电场母线的频率曲线振荡幅值和风机转子角速度曲线的振荡幅值呈现减小的趋势。最后针对风力发电机的电气参数对风机转子角速度在扰动后的振荡幅度的影响进行了分析。

At first, a mathematical model of physical structure of constant speed wind turbine and doubly fed induction generator was set up. Then two machine-infinite system simulation models were set up with software named PSAT. The dynamic responses of different capacity of wind power integration into grid in different type of faults were compared. With the capacity of wind power getting increasing, the frequency of wind power bus and the rotor angle speed oscillation would decrease. At last, the effect of the electrical parameters of the wind generator on the wind generator rotor angle speed oscillation was analyzed.
