摘要随着社会的发展以及海上贸易的需求，船舶的载重量逐渐增加，对电力推进系统的要求越来越高，导致船舶电站复杂性增大。因此在船舶电站设计方案正式投入实施前，需要进行一系列的测试、评估。这些工作不但耗费大量人力、物力，还有一定的危险性。87023

在这种情况下，计算机仿真应运而生。在一定的仿真环境和条件下，建立系统模型，对系统进行仿真，模拟现实可能发生的工况并对结果进行分析，完善设计方案。

本文主要研究12000HP油服船中船舶电站的主发电机、轴带发电机和应急发电机，分析它们的工作原理。然后在Matlab软件的Simulink环境下，利用逻辑关系和简单的数学运算，建立主发电机、轴带发电机和应急发电机的模型，根据工况改变这个条件进行仿真，得出不同工况下相应发电机的基本参数。最后利用Web Access画出简易仪表，并把仿真数据传输到Web Access数据库里，最后在仪表上显示出来

研究结果显示，在一定的误差范围内，模型能较准确地得出不同工况下发电机组的基本参数，能为船舶电站的设计方案提供一定的基础帮助。

Abstract With the development of society and the demand of maritime trade, ship's deadweight increase gradually, on the power propulsion system requirements getting higher and higher, resulting in increasing the complexity of ship power station。 This reflected an increase in the difficulty of the management and control of power plant, improve。 So in the design of ship power station officially put into operation before and need to a series of tests are carried out to evaluate the stability of its operation。 These work not only spend a lot of manpower, material resources and certain risk。

Under these circumstances, the computer simulation arises at the historic moment。 Under certain conditions,the system model is established,and the system is simulated。 The simulation results are analyzed,and the design scheme is improved。

In this paper,we mainly study the main generator,shaft generator and emergency generator in the ship station and analysis of their working principle。Under the Simulink environment of MATLAB,using logical relations and simple mathematical operations, and establish the main generator,shaft generator and emergency generator model, according to the conditions of changing the conditions of simulation that under different conditions corresponding generator basic parameters。Then the web access to draw a simple instrument,and the simulation data to the web access database。Finally,on the instrument displayed。

Finally,the results show that the model can accurately show some basic parameters of generating units under different conditions in a certain error range。
