摘要
通过控制换热站一次侧电调阀开度调整二次侧温度是站点调控的主要手段。根据站点不同节能等级建筑、不同采暖方式制定对应的二次侧供、回水平均温度,作为电调阀控制器设定值,二网供、回水平均温度实际值温度作为返回值,根据两者的偏差进行调节。基于不同类别的二网均温调节曲线实现了一种快速响应式全网自动控制系统,并进行实际案例应用。研究表明,该调控系统可根据供热负荷变化实现各站点热量按需快速响应式调整,从而达到系统整体节能目的。
Adjusting the secondary side temperature by controlling the opening of the primary side electric regulating valve of the heat exchange station is the main means of station regulation.According to the different energy-saving buildings and different heating methods used in the station,the corresponding average temperature the supply and return water on the secondary side is set as the set value of the electric regulating valve controller,and the actual value temperature of the average temperature of the supply and return water on the secondary network is taken as the return value,which is adjusted according to the deviation between the set value and the return value.Based on different kinds of temperature equalization curves of secondary networks,a fast response automatic control system for the whole network is implemented,and an actual case is carried.The research shows that the control system can realize the quick response adjustment of heat in each station on demand according to the change of heating load,thus achieving the overall energy saving purpose of the system.
