摘要
从电机学基本原理出发,建立了用电压源代替转子绕组电气注入的双馈感应发电机3阶动态模型。该模型阶数较少,物理意义明确,适用于描述调速范围较大的双馈感应发电机,例如大型变速恒频风力发电机组中的双债感应发电机,并且应用MATLAB对该动态模型进行了仿真研究,仿真结果表明了该模型的正确性。
Based on the theory of induction motor, a dynamic model for double-feed induction generator is presented. In this model, voltage sources replace electrical injections of the rotor circuit. The model is simple with definited physical meaning and it is applicable to describe the generator with wide speed range such as the generator in variable speed wind turbines (VWT) . Finally, a dynamic simulation of the model is developed by using MATLAB, and the results prove the model correct.
