Abstract :
In this paper, a PWM current source converter is proposed for high-power wind energy system using a Permanent Magnetic Synchronous Generator (PMSG). The current source converter normally requires filter capacitors on its ac side, which may affect power factor of the system. A decoupled active/reactive power control algorithm is proposed for the grid-side power factor adjustment. The dc current reference is generated in a way to meet the requirements from both sides. In addition, Field Oriented Control theory is used for the wind generator control. Experiments on a small-scale laboratory have been carried out to verify the analysis and experimental results are presented.
