Abstract :
According to the operation performance of Doubly-fed wind power system, a novel soft grid connection strategy with initial error compensation is proposed in this paper. Grid connection mathematical model of doubly-fed induction generator is deduced, and soft grid-connection control system of DFIG is designed based on the stator flux orientation vector control technique with the rotor current dynamic regulation considered. The simulation models of the DFIG wind power system were established based upon Matlab/Simulink, and experiments on the platform of 1.5MW DFIG wind power system were done to verify the proposed control strategy. The results have proven no surge current grid connection for DFIG and verified its correctness and effectiveness.
