This paper first introduces the basic theory of double-fed wind power generation system, and builds the mathematical model in two-phase rotary coordinate system. In order to deal with the strong coupling problems, the vector control technology is introduced, and the idea of dual-fed generator stator-flux-oriented vector control strategy is presented. Based on the two-phase simplify mathematical model...
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...
