LNG船推进系统动态性能建模与仿真

介绍了LNG船柴油机推进系统和电力推进系统的结构、特点及性能，讨论了其数学模型，并利用MATLAB实现了对这两种推进系统的数字仿真。采用了分层结构和模块化设计，能够实现船舶推进系统的稳态、动态仿真等计算功能。通过对仿真结果的比较，综合分析了两种推进方式的优缺点以及在未来LNG船上的应用前景。

Modeling and Simulation of the Dynemic Characteristic of LNG Ship Propelling Systems

Structure,features and peformance of both diesel propelling system and electric propelling system used in LNG ships were introduced.Its mathematical model was discussed and the digital simulation of both propelling system was realized by MATLAB.Using hierarchical structure and modular design,the Simulation was able to compute the power of steady and dynamic state either,through the comparison of simulation results,a comprehensive analysis of the two ways to promote the advantages and disadvantages was summa...
