| 摘 要： | 介绍了双馈异步发电机(DFIG)的运行原理,通过坐标变换建立了DFIG在同步旋转坐标系下的数学模型。采用定子磁链定向矢量控制策略,建立了基于功率和电流双闭环控制策略模型。并利用Matlab/Simulink仿真软件对控制策略进行仿真,在仿真模型下进行了最大风能追踪和并网运行特性的研究,仿真的结果证明了控制算法的正确性和良好的控制性能。

| Abstract: | Running theory of the DFIG is introduced,and the mathematics model of DFIG in the synchronous rotary coordinate is established by coordinate transformation.The stator flux oriented vector control strategy is used to build up the control strategy model based on power and current dual-closed-loop control strategy.It is simulated by means of Matlab/Simulink software.The maximum wind tracking and operational characteristics of grid are researched under the simulation model.The simulation results prove the valid... |
