摘要
整流器是风力发电系统中不可或缺的核心部件,针对风力发电系统能量随机波动的缺点以及传统整流方式的不足,设计了一种基于同步旋转坐标系下双闭环控制的三相PWM整流器。网侧采用空间矢量脉宽调制技术(SVPWM)及电流前馈解耦控制,实现了直流母线电压可调及高功率因数运行。仿真及实验结果充分证明了该PWM整流技术在风力发电系统上的应用是可行的、有效的。
Rectifier was an indispensable core module of wind power generation system. Three-phase PWM rectifier based on DSP was put forward by the disadvantages of random fluctuation about wind energy and the deficiency of the traditional rectifier. The space vector pulse width modulation strategy (SVPWM) and the current feed-forward compensation based on synchronous rotation frames were used. The circulating of voltage's tracking and unity power factor was achieved. The simulation and experimental results show PWM rectifier applied in wind power generation system is valid and feasible,
