摘要
船舶电站受到大扰动后,系统的结构或参数将发生较大的变化。本文设计并建立了电站柴油机系统、负载静态和动态计算、发电机及励磁调节系统的数学模型;依据有限容积法模型建立了电站柴油机仿真的实时算法,从恒定阻抗法、电动机机电暂态过程动态特性、负荷的静态特性三方面对船舶电站负荷进行归类计算,提高了负荷的动态和静态仿真性能;励磁系统采用三阶模型进行建模。通过matlab/SIMULINK进行了系统的稳态和暂态仿真建模,并用Visual Basic语言在Windows 2000操作系统上开发了仿真模型的算法和人机对话界面系统。
The structure and parameter of the marine diesel power station varies greatly after suffering strong disturbance.The marine power station diesel system,calculation methods of load in both static and dynamic state,as well as the mathematical model of excitation regulating system are designed and built in this paper.Real-time algorithm of the diesel simulation is built with volumetric method,power station load is calculated in three aspects,where invariable impedance method is included.Motor electromechanical transient state dynamical characteristics,load static characteristics and power station loads are classified to improve the static and dynamic performance of the power station.Modeling the excitation system is achieved with a three-state model.Modeling the static and dynamic simulation is achieved with MATLAB/SIMULINK.The simulation software is developed for the implementation of models and man-machine interface is designed with Visual Basic programming language under Windows 2000 operation environment.
