摘要

永磁直驱风力发电系统中可采用全功率双脉宽调制（PWM）变换器作为永磁同步发电机（PMSG）的并网电路，当风速变化时，双PWM变换器的直流链电压会随着PMSG输出功率的改变而出现大幅度波动，这将不利于变换器功率器件的安全运行及整个发电系统的稳定运行。结合永磁直驱同步风力发电系统的运行特点，提出一种适用于永磁直驱风电机组的双PWM变换器协调控制策略。系统仿真和实验结果验证了所提出的控制策略的正确性，该方案可显著提高风速变化时双PWM变换器的直流链电压的稳定性，有助于提高发电系统的安全稳定运行能力。

Abstract

The full power back-to-back pulse-width modulation（PWM） converter can be used to connect the permanent magnet synchronous generator（PMSG） with the power grid. The DC-link voltage of the back-to-back PWM converter will excessively fluctuate with the output power change of the generator when the wind speed changes， which has adverse effects on the safe operation of the converter power devices and the generation system. A coordinated control strategy of back-to-back PWM converter for the permanent magnet direct-driven wind turbine is proposed based on the operation characteristics of the PMSG system. The simulation and experimental results indicate the validity of the proposed control strategy. The method can effectively improve the stability of the DC-link voltage of the back-to-back PWM converter， enhancing the safety and stability of the generation system.
