摘要
从无刷双馈电机(BDFM)转子速d q模型出发,推导出BDFM的有功和无功功率数学模型,并设计了初步的变速恒频无刷双馈电机风力发电系统功率控制策略.计算机仿真结果表明,BDFM通过定子功率绕组发电,定子控制绕组通过变频器从电网吸收或向电网反馈电能.系统响应快,稳定性好.该研究表明变速恒频无刷双馈电机风力发电的设想在技术上是可行的.
Using the rotor d-q reference frame of the brushless doubly-fed machine(BDFM),a mathematical model for the power was derived, and the power control scheme was primary designed. Computer simulation showed that when the power winding acted as generator, the power was absorbed or fed back by the control winding through the transducer, and the system responded quickly and run stably. So the technology for variable speed constant frequency doubly-fed machine wind-power generation is feasible and is of superiority and good future development.
