Abstract

This paper presents a performance enhancement of a permanent magnet synchronous generator (PMSG) system with control of generator-side converter for a wind turbine application. This method uses zero d- axis stator current control to minimize winding losses of the generator. The electromagnetic torque of the generator is correlated with the magnitude of the qaxis stator current, while the daxis stator current is regulated at zero, the control scheme decouples the dq-axis stator current control through a vector con- trol for the generator-side converter. This paper also presents mathematical analysis of the active power and stator power factor, and the maximum power point tracking (MPPT) operation. Simulation re- sults are provided to guarantee the proposed control scheme, in which the performance enhancement and eciency are evaluated.
