摘　　要：国内外船舶电站模拟器的发展严重滞后于当前船用机电设备的更新步伐,新型双馈式轴带发电机的装船使用使得现阶段的模拟器不能满足船舶机电管理人员的培训要求,制约着船员技术水平的提高。为了解决当前船舶电站模拟器匮缺双馈轴带仿真系统的不足,在此结合双馈发电机和船用轴带发电机自身特点首次建立了船用双馈轴带系统的数学模型,以定子磁链定向的方式实现了双馈轴带系统功率的解耦。并以船舶主机转速突减为仿真情景,得到了此航行工况下双馈轴带系统各物理量的变化波形,同时在实验室硬件平台上进行了对应实验。实验结果的波形与同参数下的仿真波形高度吻合,证明了所建数学模型的正确性、实用性,为双馈轴带仿真系统以及故障诊断系统的开发奠定了坚实的理论基础。The development of marine power station simulator at home and abroad lags behind the update pace of marine mechanical and electrical equipment.The use of the new type of doubly fed shaft generator on board makes the simulator at this stage unable to meet the training requirements of ship mechanical and electrical management personnel,which restricts the improvement of crew technical level.In order to solve the shortage of the simulation system of the doubly fed shaft generator in the marine power station simulator,the mathematical model of the marine doubly fed shaft generator system based on the characteristics of the doubly generator and the marine shaft generator is established,and the power decoupling of the doubly fed shaft generator system by the way of stator flux orientation is realized.Taking the speed of the main engine suddenly reducing into as the simulation scenario,the change waveforms of parameters of the doubly fed shaft generator system under this navigation condition are obtained.At the same time,the corresponding experiments are made on the hardware platform of the laboratory.The waveforms of the experimental results are highly consistent with the simulation waveforms under the same parameters,which proves the correctness and practicability of the mathematical model.Which lays a solid theoretical foundation for the development of the simulation system and fault diagnosis system of marine doubly fed shaft generator.
