摘要
为了实现双馈风力发电机组无冲击电流并网,基于电网电压定向矢量控制技术,提出了一种考虑转子电流动态调节特性的双馈风力发电机组空载并网控制策略。基于Matlab/Simulink仿真平台,建立了双馈风力发电机系统及其并网控制的数学模型,并对不同初始运行转速的双馈风力发电机组的自动并网运行特性进行了仿真。仿真实验结果证明无论初始转速为同步转速,还是超、亚同步转速,利用提出的并网控制策略,双馈风力发电机组能很好快速地建立定子电压,并网过渡过程定子电流基本没有冲击。
Based on the grid voltage orientation vector control technique,this paper proposes a no-load grid-connecting control strategy for doubly fed induction generators(DFIG) with the rotor current dynamic regulation considered in order to realize no surge current grid-connecting for wind turbine system.The mathematic models of the DFIG wind turbine system,including a rotor-side converter and the grid-connecting control strategies are established based on Matlab/Simulink software.The operational performances of au...
