大型供热系统水力仿真计算方法的研究

The Research of Flow Simulation Algorithm for District Heating System

在现有水力计算方法基础上,根据供热系统运行的实际,提出了供回管网相分离的思想,并通过加入管网的热力工况计算．设计出一个能适用于不同工况的通用的大型供热系统的仿真计算模型。该模型不仅可以对热网实际运行工况进行模拟,而且可以求出热网理想工况下的热网参数,并通过实例分析证明其正确有效。为热网的模拟分析和调节提供了依据。从而实现热力管网的管理、调度、网络仿真的集成化,为供热系统的现代化运行和管理提供了一个有力的工具。

Based on the method of water flow calculation and the system conditions of thermal network, this paper presents a method how to separate the supply network from the return network and establishes a simulation algorithm model to satisfy District Heating System. It has been proved that the model is correct and helpful to adjust District Heating System.
