摘    要:目的研究变速恒频双馈风力发电系统的空载并网结构。方法在同步旋转坐标系下建立双馈电机空载数学模型,运用矢量控制得出空载并网策略及其结构图。结果在自行搭建的10kW双馈风力发电模拟平台上进行控制策略的验证。结论空载并网过程控制简单,过渡平稳,定、转子电流冲击小,是一种适合在风电现场使用的理想并网方式。

Abstract:Purposes—To study the no-load cutting-in structure of variable-speed constant-frequen-cy doubly fed wind power generator .Methods—The no-load mathematical model of doubly-fed induc-tion generator is established in the synchronous rotating reference frame ,vector control is applied to get the strategy and structure diagram of the no-load cutting-in .Results—The control strategy is veri-fied on the 10 kW doubly-fed wind power simulation platform .Conclusions—The results show that the no-load cutting-in control process is simple ,the transition is smooth and the current impact of the sta-tor and rotor is small ,so it is a relatively ideal cutting-in way in the field of the wind power .
