摘要
为提高船舶电力系统的用电稳定性,保证船舶在空载、加载、短路等诸多工况下功率分配的合理性,采用模块化的思想,对船舶原动机及调速系统、励磁调压系统、同步发电机及发电机并车模型进行详细建模。模拟仿真单台发电机和多台发电机并车运行下空载运行、突加负载运行、突加异步电机等几种典型工况,观察同步发电机转速及端电压变化,电网电压变化,异步电动机电流及电压变化情况,避免在实船上进行典型工况故障分析和实船实验测试产生的高昂成本,仿真结果的数据对船舶电力系统的设计与研究具有积极意义。
In order to improve the power stability of the ship’s power system and ensure the rationality of the ship’s power distribution under many working conditions such as no-load,loading,short-circuit,etc.,a modular idea is adopted for the ship’s prime mover,speed control system,and excitation voltage regulation system,synchronous generator and generator parallel model for detailed modeling.Simulate and simulate several typical working conditions such as no-load operation,sudden load operation,sudden application of asynchronous motor under the parallel operation of a single generator and multiple generators.Observe the change of synchronous generator speed and terminal voltage,grid voltage change,asynchronous The current and voltage changes of the motor avoid the high cost of typical working condition failure analysis and experimental tests on real ships.The data of simulation results have positive significance for the design and research of ship power systems.
