摘　　要：在分析双馈电机动态数学模型和定子磁链定向矢量控制的基础上,针对变速恒频风力发电系统中定子有功功率PI调节器自适用能力较差,提出了用单神经元控制器代替定子有功功率PI调节器,实现双馈发电机的有功和无功功率的解耦控制以及最大风能追踪。和传统系统相比,系统对有功功率跟踪速度快、无超调。仿真结果表明系统具有优良的动、静态性能,从而验证了控制策略的可行性。Aiming to the stator active power PI regulator being low adjusting capacity, single neuron controller instead of stator active power PI regulator is presented in variable-speed constant-frequency （VSCF） wind power generation system, which is based on the dynamic mathematic model of doubly-fed maechine and the stator-flux orientated vector control. This system realizes active power and reactive power decoupling and maximal wind power tracking. Compared with the traditional system, the new system has fast active power tracking and no overshoot. The simulation results show the novel system has good dynamic and static performance, which proves the feasibility of the control strategy.
