英文摘要：

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.
