城市集中供热控制系统优化控制的目标是在按需供热的前提下做到高效节能、减排环保,而集中供热系统是一个有着非线性、大滞后和强耦合等特点的多输入多输出系统,采用经典控制理论难以达到理想的控制效果.供热系统的运行调节是影响供热系统能耗的主要因素之一,本文以供热系统中的热源热量生产优化问题为主要研究内容,提出一种基于执行依赖启发式动态规划(ADHDP)算法的热源总供热量优化控制方法,在满足热用户供热需求的前提下,以系统总能耗为目标函数,求解获得热源出口优化供水温度和供水流量设定值.编写Matlab程序进行了仿真实验,实验结果表明了该方法的有效性,具有显著的节能效果.
The goal of optimal control of urban central heating control system is to achieve energy saving and emission reduction while heating on demand, while central heating system is a multi-input and multi-input system with nonlinear characteristics, large hysteresis and strong coupling Output system, it is difficult to achieve the ideal control effect by the classical control theory.The operation regulation of the heating system is one of the main factors that affect the energy consumption of the heating system.Taking the heat source heat production optimization in the heating system as the main research content, A total heat supply optimization control method based on ADHDP algorithm is proposed. On the premise of meeting the heating demand of heat users, the total energy consumption of the system is taken as the objective function, Temperature and water supply flow setting.A simulation program is written by Matlab program, the experimental results show the effectiveness of the method, with significant energy-saving effect.
