摘　　要：为提高教学实习船电站模拟器的动态仿真精度,提出柴油发电机组并联运行的数学模型.在模型中加入变阻抗负荷,考虑了同步发电机的定子暂态.基于MATLAB的Simulink组件,参考实船测试数据,建立柴油发电机组并联运行的动态仿真模型,实现非同期并车的冲击电流仿真和转移功率仿真.仿真波形与实测波形的比较表明,该动态模型有效.该模型已应用于实习船电站模拟器中.To improve the dynamic simulation precision of power system simulator in teaching-training ship,a mathematic model of diesel generator sets operating in parallel was presented.Variable impedance load was added to the model,and the transient state of stator of synchronous generator was considered.Referencing data from the ship test,the dynamic simulation model of diesel generator sets operating in parallel was set up based on the Simulink of the MATLAB.Impact current and load shift power simulations under the condition of asynchronous switching are realized.Comparison of simulation waveforms with measured waveforms show that the dynamic system model is effective, which has been used in simulator of the power system in teaching-training ship.
