摘　　要：采用传统的PI控制、模糊控制以及积分型变结构控制(IVSC)分别与矢量控制相结合,对双馈风力发电机空载并网控制,即并网前的空载运行、并网时的过渡过程做了仿真实验。在IVSC与矢量控制相结合的控制策略中,将饱和函数加入到切换控制,使系统在边界层内产生准滑模运动,有效地抑制了转子电流的抖振。通过比较,积分型变结构控制(IVSC)分别与矢量控制相结合的控制策略能使系统在全局范围动态性能最佳。There are three control strategies（traditional PI control ,fuzzy control ,integral variable structure control （IVSC） and the field-oriented vector control technique）are presented for double-fed wind generator＇s no-load cutting-in. In IVSC and the field-oriented vector control technique, the saturation function is employed in switch control, which can make the system to produce quasi slide mode movement in boundary layer, the chattering of rotor current is decreased effectively. Compared with the traditional PI control,fuzyy control is given. IVSC is verified optimal by corresponding simulations with PSCAD for no-load operation before the cutting- in, the transient process at the cutting-in moment.
