针对我国液化天然气(Liquefied Natural Gas,简称LNG)船舶轮机管理人员的培训全部依赖于国外昂贵产品的现状,以国产首制LNG船为母型船,开发了国内首套LNG船推进仿真系统.该系统既可独立运行;亦可与其他系统连接,构成整体系统运行;方便灵活.在实际的编程实现中,对实时仿真系统中仿真模型程序与仿真软件界面程序,提出了实现的优化方法;通过不同的子模型采用不同的仿真算法、模型程序全局变量与内部变量分离、模型程序与界面程序分离运行等机制,解决仿真系统中实时性和准确性的矛盾问题.该系统的成功开发,对推动我国LNG船舶轮机管理人员的教育与培训有着重要意义.

It is entirely dependent on foreign expensive engine simulators of LNG carrier at present stage in China for marine engineers to be educated and trained. With respect to the propulsion system of domestic LNG carrier, first set of domestic LNG carrier propulsion simulation system is developed with high-level computer programming language. The system is convenient and flexible, which can run independently and can also be connected with other systems to constitute the whole simulation system. An actual programming optimization method is proposed to realize the real-time simulation and interface programming in simulation software. Different simulation algorithms are applied to different sub-models; model global variables are separated from local variables; model program and software interface program runs separately to resolve the contradictions between real-time ability and accuracy of the simulation system. The successful development of the system will promote China's LNG carrier engineers’ education and training.
