摘要
根据变速恒频双馈风力发电机组的运行特点,将矢量变换控制技术应用于发电机并网控制。利用Matlab软件建立空载并网仿真模型,对并网前的空载运行、并网时的过渡过程进行了仿真研究。仿真结果表明,所采用的空载并网技术是变速恒频双馈风力发电机的一种较理想并网方式。
According to the operation performance of variable speed constant frequency （VSCF） doubly - fed wind - energy generator set, vector control technique is presented to be used for grid connection control of generator. Using the Matlab software, a no - load grid - connected simulation model is established and applied to make a comprehensive system simulation on the no - load operation before the connection with the grid and the transient process at the connection moment. Both simulation and experiment studies prove that the proposed no - load grid - connected scheme is a relatively ideal approach for VSCF doubly - fed wind - energy generator.
