摘　　要：由于建筑所采用的节能技术有较大差异,传统的集中供暖系统控制方式不能保证建筑群体的室内舒适性温度,无法根据建筑群体供暖需求量有效分配各循环水泵的工作量。本文考虑相邻室温影响,建立了基于状态空间法室内温度控制数学模型并进行验证分析。采用模型预测分布式群控方法对建筑室内温度进行控制与优化,并根据预测后的需热量对换热站循环水泵进行分布式群控优化。实验结果表明,在相同室内外环境下,所建立的室内温度控制数学模型能够很好的反映实际室内温度和阀门开度;基于分布式的室内温度模型预测群控能够有效的调节室内温度并稳定跟踪各室内温度设定值,相较于传统温控阀控制方式其热能能耗降低14.28%。同时循环水泵群控优化后的效率提高了16.74%。The indoor thermal comfort temperature of the building groups cannot be guaranteed by the traditional central heating system control mode,and the workload of each circulating water pump cannot be effectively distributed according to the heating demand of the building groups due to the large difference in energy conservation technology used in the buildings.In this paper,a mathematical model of indoor temperature control based on the state-space method was established and verified on the basis of considering the influence of adjacent room temperature.The model prediction distributed group control method was adopted to control and optimize the indoor temperature of the buildings,and the circulating water pump of the heat exchange station was optimized by the distributed group control according to the predicted heat demand.The experimental results show that under the same indoor and outdoor environment,the actual indoor temperature and valve opening can be well reflected by the established mathematical model of indoor temperature control;The indoor temperature can be effectively adjusted and the set value of each indoor temperature can be stably tracked based on the distributed indoor temperature model prediction group control,with its thermal energy consumption reduced by 14.28%compared with the traditional temperature control valve control method.At the same time,the efficiency after the group control optimization of circulating water pump has increased by 16.74%.
