Research on Modeling and Excitation Start Method of Dual Stator-Winding Wind Turbine

This paper revolves around the application of the dual stator-winding induction generator in the field of wind power generation. It involves establishing a mathematical model of the dual stator-winding wind turbine and proposing an excitation start-up method for the generator. The study begins by describing the structure, working principle, and excitation start-up method of the dual stator-winding generator, and leverages the Matlab/Simulink to establish the simulation model of the dual stator-winding induction generator. In this study, we conducted simulation and analysis to evaluate the performance and excitation starting method for the generator and carried out a prototype test. The results demonstrate that the dual stator-winding wind turbine can obtain a stable low-voltage power supply at the auxiliary winding end of the generator at different speeds by adjusting the rotor excitation currents, and can provide stable excitation voltage for the rotor end through the converter. Moreover, the stator end of the generator can yield stable-frequency and high-voltage output.
