【摘要】 提出了几种变速恒频风力发电机组的变流装置,重点分析了矢量控制策略在风力发电系统中的应用,并建立了基于定子磁场矢量定向控制模型。结果表明,采用这种协调控制策略时,直流母线电压波动很小,电压调节更加迅速,具有十分重要的应用价值。更多还原

【Abstract】 Several kinds of convertors for the variable speed constant frequency(VSCF) wind power generation unit were presented.The vector control strategy was applied to wind power generation systems,and the model of stator magnetic field oriented vector control was established.Research demonstrated that the DC-link voltage fluctuation was small and the voltage regulation was fast by using this strategy.更多还原
