Application of matrix converter for variable speed wind turbine driving a doubly fed induction generator

In order to meet power needs, taking into account economical and environmental factors, wind energy conversion is gradually gaining interest as a suitable source of renewable energy. In this paper, a grid connected wind power generation scheme using a doubly fed induction generator with a direct AC-AC matrix converter is proposed. The aims of this paper are: to model and to simulate the operation of a doubly fed induction generator; the analysis employs a stator flux vector control algorithm and a space vector modulated matrix converter to control rotor current; the matrix converter-based rotor current control scheme is highlighted; the system enables optimal speed tracking for maximum energy capture from the wind and high performance active and reactive power regulation used the RST regulator. Lastly, the obtained simulation results, for different operating points, are presented illustrating the good control performances of the system
