Optimized servo-speed control of wind turbine coupled to doubly fed induction generator

<p>Optimal control of any variable speed wind turbine needs maximum power point tracking (MPPT) coupled to doubly fed induction generator (DFIG) for better generation. This paper offers a novel direct servo-speed turbine. latter is based on DFIG optimal hysteresis MPPT inverter current combined with space voltage modulation (SVM) technique, thus providing stable and continuous energy flow grid. In this design, the asynchronous machine stator directly connected Bidirectional converter, acting as frequency rotor circuit located. Rectifier supplies windings voltages reference resulting from procedure exchange between Inverter controlled by means SVM technique maintain (DC) bus constant. Simulation results show that proposed configuration improves converters efficiency due less than which injected into grid.</p>
