摘要
本文基于质量和能量守恒宏观角度,分析了球磨机制粉系统对象的特性,应用系统动力学原理,以因果回路图和存量流量图为载体,提出了球磨机制粉系统的系统动力学建模方案。并将仿真曲线与传统模型的仿真曲线对比分析,验证了模型的准确性。所建系统动力学模型结构层次清晰,繁简适当,可很好的贴近实际系统。同时,系统动力学可以为整个火电厂的建模和优化提供一种新的思路和方法。
Based on the macroscopic angle of mass and energy conservation,this paper analyzes the characteristics of ball mill coal pulverizing system deeply. By using the principle of system dynamics and taking causal loop diagram and stock and flow diagrams as its carriers,it proposes a modeling scheme of ball mill coal pulverizing system. In addition,through comparing and analyzing simulation curves of the new and traditional models,and the accuracy of system dynamics model can be verified. The system dynamics model's structure is with distinct hierarchy and suitable complexity,which is well closed to the actual system.Meanwhile,system dynamics provides a new idea and a method of modeling and optimization in the whole coal-fired power plant.
