Research on Dynamic Model of Double-Feed Induction Generator

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.
