Research on the control strategy of wind turbine with a doubly-fed generator and its simulation

The wind power is a kind of clean and renewable energy way of generating electric power. In the wind turbine technology, the doubly-fed induction generator (DFIG) drive is one of the most frequently applied variable speed generator drive concepts. In terms of the basic principles of the DFIG, the mathematical model of DFIG is founded. Then the control strategy based on the stator voltage directional vector control is primarily analyzed. According to the mathematical model, the simulation based on Matlab is done, and provides the theoretical basis for the future experiments. The simulation result verifies that the theory is accurate and efficacious.
