摘要：

A novel algorithm of dual space vector modulation (SVM) for two-stage matrix converter (TSMC) is proposed, which does not calculate real-time modulation factor of rectifier stage. Utilizing grid voltage oriented vector control strategy, decoupling control for active and reactive power generated by doubly fed induction generator (DFIG) is proposed. Then the model of grid-connection wind energy conversion system (WECS) consisting of doubly fed induction generator (DFIG) excited by TSMC is built up using MATLAB/SIMULINK. Finally, performances of low voltage ride-through (LVRT) for WECS using proposal control strategy under grid fault are illustrated by simulation. And results indicate: I. transient performance of LVRT for WECS during grid fault is good; 2. active and reactive power generated by DFIG supplying to grid never occur long-time oscillation after grid fault clearance; 3. proposed control strategy promotes dynamic and steady-state performances of WECS.
