摘　　要：新型船用双馈式轴带发电机具有传统同步式轴带发电机不可比拟的优点,并得到了广泛应用,但是当前国内船舶电站模拟器仍采用传统的同步式轴带发电机仿真系统,严重制约着船员实操培训的更新步伐。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,针对双馈电机及船用轴带发电机的特点首次建立了船用双馈轴带系统的数学模型,采用定子磁链定向的方式实现了功率的解耦,并对双馈轴带在次同步工作状态下进行了仿真分析,仿真波形中各物理量的变化趋势满足实际物理量之间的数学关系,证明了所建数学模型的正确性,为双馈轴带仿真系统的开发奠定了理论基础。The new type of marine asynchronous shaft generator has the incomparable advantages of the traditional synchronous shaft generator and has been widely used.However,the traditional synchronous shaft generator simulation system was still used in domestic ship power station simulators,which seriously restricted the renewal of crew training.In order to overcome the shortage of the simulation system of doubly fed shaft generator for ship power plant simulator,in this paper,the mathematical model of marine doubly fed shaft system was established for the first time,according to the characteristics of doubly fed machine and marine shaft generator.This paper realized power decoupling by stator flux orientation,and simulated and analysed the asynchronous shaft generator under sub-synchronous working condition.The changing trend of each physical quantity in the simulation waveform meets the mathematical relationships of actual physical quantity,which proves the correctness of the mathematical model and lays a theoretical foundation for the development of the simulation system of asynchronous shaft generator.
