| 摘 要： | 传统的风力发电机组直接并网和降压并网都会在并网瞬间产生很大的冲击电流,基于定子磁链定向的双馈发电机组空载并网,由于并网前定子磁链的检测不准确也会对电网造成冲击.根据变速恒频双馈风力发电机组的运行特点,通过对其数学模型的分析,建立了双馈异步发电机的空载数学模型,研究了其基于电网电压定向的空载并网控制策略,避免了由于定子磁链检测不准确造成的电网冲击.试验结果表明,该控制策略可以实现大容量风电机组的无冲击软并网,是一种理想的风电机组并网方式.

| Abstract: | The current impact of directly or step-down cutting-in of traditional wind power generation is extremely high,and the stator field-oriented vector control is in the same way due to inaccurate stator flux.By analyzing the operation behavior and model of variable-speed constant-frequency (VSCF) wind power generation based on doubly fed induction generator (DFIG),the model of DFIG with no load was founded,and a idle load cutting-in control strategy was developed based on grid voltage orientation.The experiment... |
