摘要：定子双绕组异步风力发电机是为了适应变速范围较宽的风力发电以及船艇、车辆等电源系统的新发展而提出的系统。它的定子设有两套绕组，一套是功率绕组，输出端接有励磁电容、滤波电容、整流器，输出变频交流电或整流直流电压；另一套是控制绕组，接有静止的励磁变换器，可以为发电机连续地提供励磁，解决了异步发电机在负载和转速都大范围的变化时，所需要的大范围变化的励磁电流调节等问题。两套定子绕组在电气上没有直接连接，仅是通过磁耦合，容易达到高性能的控制。
定子双绕组异步电机风电机组与当前风电主流产品有刷双馈异步和直驱永磁同步机组相比具有很多固有的优点，首先定子双绕组感应电机在结构上继承了传统异步电机的优点：转子为笼型，结构简单坚固，无电刷和滑环，可适应复杂恶劣的环境，电机成本低、以及功率密度高等优点，其次系统所需励磁变换器容量仅为额定容量的三分之一，即可通过灵活的控制策略，实现连续调节发电机励磁无功，获得高品质的电能。
本文以定子双绕组异步电机风力发电系统为研究对象，阐述了其基本工作原理，给出了数学模型，针对其输出稳定电压的控制要求，研究了其用于风力发电系统的控制策略。论文重点对定子双绕组异步风力发电系统的正常运行做了仿真研究，将系统的数学模型和控制策略在SIMULINK中建立模型，通过仿真结果验证控制方案的准确性及系统的可行性。

Simulation Study of Dual Stator Winding Induction Motor wind power generation system
Abstract: Dual stator-winding induction generator is to adapt to new developments in a wide range of wind speed and aviation, combat vehicles, such as the power system and the proposed. It has two sets of stator windings, a set of power winding, excitation output termination capacitors, rectifier, filter capacitor, the output frequency AC or DC voltage rectifier, Another set of control winding is connected with a stationary transducer excitation, the excitation can be continuously provided to the generator, induction generator to solve a wide range of speed and load are in the variation range, the required change in the field current controller issues. By optimizing the design of a control strategy and system parameters, in a wide speed range and variable load conditions, with a small amount of excitation capacity to effectively control the inverter power output, ora small current to effectively control the excitation transducer the large current power output to maintain a constant output voltage amplitude, effectively reduce the system cost, size and weight. Two stator windings are not directly electrically connected only through the magnetic coupling, easy to control, high-performance.
