摘　　要：分析实际船舶电力系统,将同步电机理想化,忽略定子暂态,考虑转子阻尼绕组作用,建立简化的五阶同步发电机数学模型.应用计算机仿真技术,并结合实际,实现船舶同步发电机电力系统的仿真.分别对同步发电机、负载、励磁建模,在Matlab开发环境下,借助Simulink工具,选择合适的参数,对船舶同步发电机系统进行仿真.对发电机系统突加负载和突卸负载的仿真表明,该模型是准确有效的.The simplified five-step mathematical model of synchronous generator is built by analyzing the real power station system under the condition of considering the rotor winding damping effect but ignoring the stator transient.Applying the computer simulation technology,the ship synchronous generators simulation system is realized combining with practical situation.The mathematical models of synchronous generator,load and excitation are established respectively,and the synchronous generator model is simulated with Matlab/Simulink by choosing proper parameters.The simulation of loading up or down suddenly on the synchronous generator system shows that the proposed model is precise and effective.
