摘　　要：针对工程应用中集中供热系统的换热站调节策略单一、参数动态调节能力不足的问题,根据热平衡方程及管网特性,提出基于室外温度与室内预设温度的供水温度调节模型和流量调节模型,并引入系数对相对负荷进行修正。在此基础上设计具备实时动态调控能力的换热站节能控制系统,并应用于换热站的实际运行控制。测试结果表明,在满足供热需求条件下,可实现二级管网热水泵节省电量30.47%,节省热量16.50%,具有良好节能效果,可为集中供热系统换热站的节能运行提供参考。This paper aims at the problems of single adjusting strategy and insufficient dynamic adjusting ability of parameters in heat exchange station of central heating system in engineering application.According to the heat balance equation and the characteristics of pipe network,the water supply temperature regulation model and flow regulation model based on outdoor temperature and indoor preset temperature are put forward,and the relative load is modified by introducing coefficient.On this basis,the energy-saving control system of heat exchange station with real-time dynamic control ability is designed applied to the actual operation control of the Heat Exchange station.Under the condition of meeting the heating demand,the test results show that the electricity of secondary network hot water pump and heat can be saved by 30.47% and 16.50% respectively.It has good energy-saving effect and can provide reference for energy-saving operation of heat exchange station in central heating system.
