基于仿真技术的动力装置优化设计技术研究

Application of simulation technology to design of power plant

针对传统动力装置设计方法中存在计算复杂、动态性能难以计算等问题,提出利用动力装置仿真系统来设计船舶动力装置的方法。首先,利用模块化建模原理建立了动力装置各组成部件的数学模型,然后利用C++语言编写了各模型的仿真程序,并建立了动力装置仿真系统。利用该仿真系统对某型船舶的全燃动力装置进行了详细设计,设计过程及结果表明,采用仿真系统来设计动力装置可以准确计算动力装置的动态性能,同时对动力装置各部件的性能参数进行优化。

In designing the power plant there are many problems with the traditional design method, for instance, the calculation is very complex, and the calculation of the dynamic characteristic is very difficult. So this paper puts forward the method of designing the power plant by using the simulation system of power plant. Then the mathematical model of a power plant is established by using the technology of modular modeling, and the simulation program is drawn up with C＋ ＋ language to build the simulation system. Using the simulation system, a combined gas turbine with gas turbine power plant is designed. The design process and the result indicate that this design method can exactly calculate the dynamic characteristic of the power plant, and meanwhile optimize the characteristic parameters of every component.
