| 摘 要： | 研究了一种基于混合励磁同步发电机与矩阵变换器组合的宽转速范围的变速恒频发电系统。在理论推导该新型发电系统数学模型的基础上,提出了一种将发电机端电压闭环控制与矩阵变换器输出电压的瞬时值闭环控制相结合的两级式电压闭环控制策略,并通过推导闭环系统传递函数对系统稳定性进行了分析。最后,通过实验验证了该发电系统及其控制策略的有效性。

| Abstract: | A novel variable speed constant frequency generation system was investigated,which was constructed by hybrid excited synchronous generator(HESG) and matrix converter(MC)for wide speed range application.Based on theoretical analysis on it,the mathematical model was derived,a two-stage closed loop control scheme which combined with both generator terminal voltage closed loop control and instantaneous value closed loop control of matrix converter output voltage was proposed.The transfer function of the generation system was deduced to analyze system stability.At last,the validity of HESG-MC system and its control method are verified by experiments. |
