【Abstract】 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.更多还原
