摘　　要：本文以某型船舶电站为仿真对象,依据电站工作原理及网络结构,重点研究发电机励磁系统数学模型和柴油机与调速系统数学模型,然后在Simulink中分别建立了船舶电站的同步发电机模块,柴油机及其控制系统模块和大功率负载模块,完成某型船舶电站仿真平台设计方案。通过搭建的仿真模型对船舶电站单机运行和双机并车进行仿真实验,模拟电站正常运行和对地短路故障工况,分析船舶电站的不同参数的变化情况。仿真结果显示搭建的船舶电站仿真平台各电气环节特性与实际系统非常接近,电站系统相关参数测量值和变化趋势与实际系统参数接近。研究表明该设计方案可以用于船舶电站系统全面仿真,仿真平台设计方案具有通用性,可应用于不同船型电站系统设计与仿真。Based on the working principle and network structure of the power station,this paper focuses on the mathematical models of the generator excitation system and the diesel engine and speed control system.The synchronous generator module,the diesel engine and its control system module and the high-power load module are established respectively in Simulink to complete the simulation platform design of a certain type of ship power station.Through the built simulation model,the simulation experiment is carried out on the single operation and dual-machine parallel operation of the marine power station,the normal operation of the power station and the short-circuit fault condition to the ground are simulated,and the change of different parameters of the marine power station is analyzed.The simulation results show that the characteristics of each electrical link of the built simulation platform are very close to the actual system,and the measured values and changing trends of the relevant parameters of the power station system are close to the actual system parameters.The research shows that the design scheme can be used for the comprehensive simulation of ship power station system,and the design scheme of simulation platform is universal and can be applied to the design and simulation of power station system of different ship types.
