摘要
消磁船主发电机组所带的是典型的脉冲负载 ,具有变化幅度大和依次递减的特点。本文在介绍了其负载特点的基础上 ,考虑到对负载的适应性和经济性 ,分析了影响该类系统选型的因素 ,包括柴油机额定功率、飞轮转动惯量、调速器动态性能和机组工作转速等 ,结合多目标寻优理论得到了寻优问题的模型 ,并利用仿真的手段实现了一实例计算 ,得出了几点在实际选型时值得考虑的结论。
The load of the main diesel generating system on a degaussing ship is impulsive, which rise to the maximum value and drop to the minimum value in very short time, and its ranges are degressive. In this paper, based on the analysis of the load characteristics, and take the adaptability and economics into account, the factors like the rated power of diesel engine, the flywheel inertia, the governor's dynamic performance and the working speed which will affect the system's dynamic performance and cost are analyzed. An optimizing model which takes advantage of multiple-objective optimizing theory for the design of this kind of system is achieved. And based on this model, a design instance is committed by the using simulation method. At last, some conclusions which are worth consideration during realistic design are presented.
