摘要
为了提高风力发电机并网运行性能,提出一种符合大功率直驱并网永磁风力发电机要求的变流器电路拓扑结构.针对现有永磁直驱风力发电系统并网方案,设计了不可控整流、升压斩波、正弦脉宽调制SPWM逆变电路的控制方案,并对电路中升压斩波电路和SPWM逆变控制系统结构进行了重点分析.采用Matlab/Simulink软件进行系统并网仿真,结果表明,该控制方法可满足风力发电机运行的需要,证明了该方法的可行性和正确性.
The converter circuit topology satisfying the requirement of high-power direct-drive grid-connected permanent magnet wind power generator was proposed in order to improve the grid-connected performance of wind turbine. The control scheme based on uncontrolled rectifying, boost chopping and sine pulse-width modulation （SPWM） inverter circuit were designed for the existing grid-connected scheme of direct-drive permanent magnet wind power generation system. The boost chopping circuit and SPWM inverter control system structure were emphatically analyzed. The Matlab/Simulink simulating results show that the proposed control method can meet the requirement of wind power generation system. The feasibility and correctness of the method has been proved.
