Study on modeling and simulation of double-fed induction wind power generator control system

Double-fed induction generator (DFIG) is took as a research object in this paper, a relatively complete mathematical model of DFIG control system including wind turbines, driving system and generator has been established. Besides, a variable-speed variable-pitch control strategy is put forward and some simulation models of DFIG based on MATLAB / SIMULINK are built and realized. Then, take step change wind speed and turbulent random wind speed as examples to make simulation research on the operating characteristics of wind turbine. Simulation results validated the rationality of the models and the feasibility of the control strategies.
