Recently, an increasing number of multi-MW (1MW and up) wind generating set are being developed with a variable speed-variable pitch (VS-VP) control strategy to improve the fast response speed and get optimal energy. But the power generated by wind turbine changes rapidly because of the continuous fluctuation of wind speed and direction, and wind energy conversion systems are of strong nonlinea...

Wind is one of the most widely used nonconventional sources of energy. A back-to-back PWM converter is used as the excitation power supply for the doubly fed induction generator (DFIG) wind power generation of variable speed constant frequency (VSCF).The Simulink model and control strategy of converter which is connected between rotor and grid is analyzed. Stator-flux oriented vector control ap...

The proposed control algorithm is applied...

As one of the most promising Distributed Generation (DG) sources, wind power technology has been widely developed in recent years. Doubly fed induction generator (DFIG) is currently employed as one of the most common topologies for wind turbine generators (WTGs). This generator operates as a synchronous/asynchronous hybrid generators. Therefore, it is necessary to power engineers find understan...
