To minimize the reactive power of the converter of the control winding in the novel dual stator-winding induction generator based on the PWM converter, design features of the induction generator with a rectified load are proposed. The optimization method of excited capacitors to minimize the reactive power of the control winding at a variable speed is given. The calculation capacity of the machine with a diode bridge rectifier load is proposed. To achieve global searching, the integrated method with the improved real-coded genetic algorithm and the twodimensional finite element method （FEM） is introduced. Design results of the sample show that reactive power can be reduced by the method, and the converter capacity can be decreased to 1/3 of output rated power at the speed ratio of 1 ： 3, thus reducing the volume and the mass of the inverter.
利用S-Function建立了新型双绕组异步发电机的Simulink核心模型,并利用Power Systems Blockset工具箱把核心模型转换为PSB模型,以利于与外部电气元件直接相连。由此建立了基于控制绕组定子电压定向控制的带整流桥负载的系统通用仿真模型,并对空载和额定负载下的变速运行分别进行了仿真与试验研究。结果表明,该仿真系统具有良好的运行性能。
