热水锅炉供暖系统的模型辨识

Study on boiler heating system model

热水锅炉供暖时只根据锅炉出水温度来决定供暖温度的方法缺少科学的理论依据 .根据热力学定律构建了锅炉供暖系统的基本数学模型 ,并在几个锅炉系统的管网中加入了测点 ,采集到大量室外温度、室内温度、出口温度等数据 ,用最小二乘法辨识出供暖模型中的未知参数 ,绘制出室内温度在1 8℃时的供水温度的函数曲线 。

It is short of theoretical foundation to adjust heating temperature only according to output temperature of boilers.On the basis of thermodynamics theory and temperature data of outdoors,indoors and boilers output,constructed a basic mathematical model.Moreover,identified the parameters in this heating model by least square method.According to the function graph of output temperature and supply water temperature,boiler manipulator can control the boiler output temperature more reasonable.
