Study on Direct-Driven Wind Power System Control Strategy

Abstract:

The development of direct-driven wind power system using permanent magnet synchronous generator (PMSG) is very fast, and the back-to-back converter has been paid much attention for its excellent performance. The work principle of the generator-side converter (GSC) and control strategy of PMSG are explained in detail, and the steady-state and dynamic performances are analyzed by simulation. The experimental prototype is built to achieve generation and motor state operation, and the vector control of PMSG is realized by generator-side converter. The simulation and experiment results show that using PWM converter as generator-side converter for direct-driven wind power system with PMSG, can achieve good control performance for PMSG and provide possibility to supply excellent power energy transmitted to power grid.
