摘 要: 双馈风力发电采用变速恒频发电技术,通过转子侧交直交(AC-DC-AC)变流器,对双馈电机实现功率因数可调的四象限运行。变流器采用机侧、网侧双脉宽调制(pulse width modulation, PWM)控制策略和旋转坐标系下电流内环、转速外环及电压前馈解耦控制。通过Matlab仿真,分析风机的调速跟踪和抗负载扰动性能,验证了控制策略的有效性。
关 键 词: 电气工程;脉宽调制;变速恒频;双馈风力发电

Abstract: Doubly fed induction generator (DFIG) uses variable speed constant frequency (VSCF) technology, and realizes four quadrant operation with adjustable power factors to doubly-fed wind power generator though rotor side AC-DC-AC converter. The converter adopts pulse width modulation (PWM) strategy at rotor side and grid side, and uses current inner loop, speed outer loop and voltage feedforward decoupling control. By Matlab simulation, the paper analyzes the speed regulation tracking and load disturbance resistance performance, and demonstrates the effectiveness of the control strategy.
Key words: electrical engineering; pulse width modulation; variable speed constant frequency; doubly-fed wind power generation
