A grid-connected wind-power generation scheme using a doubly-fed induction generator (DFIG) in conjunction with a direct AC-AC matrix converter is proposed. The analysis employs a stator-flux vector-control algorithm and a space vector modulated matrix converter to control the generator rotor current. The system enables optimal speed tracking for maximum energy capture from the wind and high performance active and reactive power regulation. The paper discusses the operating principles of this power generation scheme. The matrix converter-based rotor current control method is described. Simulation studies of the proposed power generation system were carried out. Results obtained are presented illustrating good control performance of the system.
