Abstract

Proposed is a control strategy of voltage and frequency control for a doubly fed induction generator (DFIG) connected to variable speed wind turbines. The scheme is based on stator voltage vector represented in a rotating polar coordinate system. Modified direct voltage control strategy for rotor side converter is used. The control pulses for the rotor side converter are supplied by the hysteresis controller. Simulation and analysis of a 5HP grid connected variable speed DFIG based on wind power generation system is presented to demonstrate the system performance in different operating conditions. The operating conditions are based on the change in wind velocity.
