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.

基于电流源变换器的风能系统无功功率控制
本文提出了一种基于永磁同步发电机(PMSG)的大功率风能系统PWM电流源变换器。电流源变换器通常需要在其交流侧安装滤波电容,这可能会影响系统的功率因数。针对电网侧功率因数的调整,提出了一种解耦的有功/无功控制算法。直流电流基准以满足双方要求的方式产生。此外,将磁场定向控制理论应用于风力发电机的控制。在一个小型实验室进行了实验来验证分析,并给出了实验结果。
