A New Type Marine Shaft Generating System Based on Brushless Doubly-fed Generator

传统船舶主机轴带发电机在提高船舶营运经济性能方面取得了很大的效益,但也存在不少问题。在简要总结传统的轴带发电系统和一种作为新型发电机的无刷双馈发电机结构特点的基础上,提出了采用无刷双馈发电机作为船舶轴带发电系统的方案。而后结合无刷双馈发电机的数学模型和船舶轴带发电系统的特点,详细分析了船舶无刷双馈轴带发电机系统的组成结构与控制措施,为其在船舶轴带发电系统的实际应用奠定了理论基础。

Traditional M/E shaft generators have brought great benefits in the respect of enhancing marine economic performance,but still,there exist some problems in them.After a brief introduction of traditional shaft generator system and the new brushless doubly fed generator （BDFG）,a scheme of marine shaft generating system with BD-FG is presented.Using the math model of BDFG combined with the structural features of marine shaft generating system,the configuration of marine BDFG shaft generating system and the measures of controlling it are analyzed in detail,which makes a theoretical support for the practical application of BDFG in marine shaft generating system.
