摘要 在新型双绕组感应发电系统中,通过选取功率绕组的励磁电容,可以实现控制绕组励磁变换器容量的最小化。采用了控制绕组定子磁场的定向控制策略,对1:2.5宽变速范围内,空载和额定负载下的运行规律进行了仿真研究,给出了系统电路参数的计算方法。结果证明,该系统在宽变速运行范围内具有较好的电压控制性能,并可以用小容量的变换器有效控制大容量的电能输出。 The minimization to the reactive power of control winding of dual stator-winding induction generator can be realized via optimal excited capacitors.The performances of the system operating with 1:2.5 speed range under no-load and rating-load are simulated based on direct flux stator control of control winding.The calculating methods of system circuit parameters are presented.The results show the good voltage control can be achieved and the large output power can be controlled by minimal capacity converter.
