摘　　要：基于定子磁链定向的并网控制策略分析,提出了一种不依赖于发电机参数的实用并网控制方法,能使机端电压与电网电压快速匹配以满足并网条件,并以小型模拟试验机组为例进行了试验。结果表明,该方法能快速、准确地跟踪电网电压,使发电机电压满足并网条件,实现"软并网"。By studying the grid connected control strategy based on stator flux linkage orientation,this paper proposes an applied scheme for the grid connected of AC-excited wind turbine generator,which the control strategy does not depend on the parameters of generator.This method can effectively control the stator voltage so that the stator voltage can fast track the voltage of power system and meet the requirement of grid connected.In order to test and verify the validity of the proposed method,experiments are carried out by using an analogous wind turbine generator.Experimental results show that the proposed method can track the voltage of the grid rapidly and make the voltage of generator meeting the conditions of grid connected,which achieves flexible grid connected.
