Simulation of Control for Without Wind Speedometer Grid-connected Doubly-fed Induction Generator

In this paper, the fundamental strategy for controlling the grid-connected doubly-fed induction wind power generation system is taken under deliberation. In varying wind speed, according to the maximum power point tracking control theory, the fuzzy controller is premeditated to reinstate the wind speedometer to track the optimum generator speed based on the generator output power error and rotation speed error. The wind turbine can contrive to operate at the optimal tip speed ratio to ensure the maximum wind energy performance coefficient, avoiding the effects of turbulence on wind speed measurement. Finally, the wind power system is built to demonstrate the feasibility of control strategy.
