【Abstract】 The decoupled control for active power and reactive power of the doubly-fed induction generator(DFIG)is a key technology of variable speed constant frequency(VSCF)wind energy generation system,which is realized by the vector control strategy.Based on analyzing the mathematical model of a doubly-fed wind power generator,the decoupling control strategy of the active and reactive power of the DFIG was deduced,and the decoupled control of active power and reactive power based on the grid flux orientation vector control technique was designed,a simulation platform of doubly-fed wind power generation system based on Matlab/Simulink and a experimental system of doubly-fed wind generator vector control based on TMS320F28335 DSP were built.The experiment was carried out on the base of the simulation research.Simulation and experiment results confirm the validity of the control strategy.更多还原
