| 摘 要： | 从物质和能量传递过程均衡性的角度,提出基于系统动力学原理,以因果关系和存量流量关系为载体,从相对宏观的层面构建电站热力系统动态模型的建模方案。论述将系统动力学原理应用于发电过程建模的适用性,以盘山电厂N-36000-1型凝汽系统为例,给出系统动力学建模的基本过程,通过仿真及实际运行数据的对比分析,验证了所建模型的有效性。研究表明,系统动力学模型具有因果关系清晰、模型表述贴切、繁简程度适当、描述现实能力强的特点,可作为发电过程建模及优化问题研究的有力工具。

| Abstract: | A novel modeling scheme based on system dynamics theory for thermal system of power generation units was presented.This scheme,in which causal loop diagrams and stock-flow diagrams were adapted as the essential tools,is more macroscopic than other methods because of its emphasizing of mass and energy balance.After detail analysis on applicability of the scheme in power unit modeling,a particular process of its implementation was demonstrated for N-36000-1 condenser system in Panshan power plant.The accuracy... |
