Control strategy of variable-speed wind power generation system with constant-frequency double-rotor generator

A novel variable-speed wind power generation system with constant-frequency double-rotor (CFDR) generator is proposed which combines the advantages of low cost, good dynamical performance and high reliability. In this paper, the structure of the proposed wind power generation system is introduced and the working principle of the CFDR generator is presented. The control strategy of the wind power generation system is discussed where vector control strategy is used. The simulation model is built under Matlab/Simulink surroundings and the simulations are carried out. The correctness and effectiveness of the proposed control strategy are verified by simulation results.
