摘要:

以天津市某住宅小区为研究对象,建设了二级网智能平衡调控系统。基于对供热的大数据分析技术,实现了分户平衡控制,并以热用户舒适室温为目标的“站荷联动”智能调控策略指导热力站节能优化运行。在保障供热质量的前提下,实现了按需供热、节能降耗。通过对改造前后的供热运行数据对比分析可知:二级网供回水温差、用户回水温度离散度、室内温度达标率、循环水泵运行频率、循环泵耗电量以及单位面积热耗等均发生了显著变化。研究结果表明,启用二级网智能平衡系统后,该小区的单位面积热耗和电耗,分别下降14%和23%,热用户室温达标率为99%,供热质量明显提高,节能效果显著。通过对本项目的研究,旨在为同类项目的改造与设计提供参考。

Abstract:

A secondary network intelligent balance system for a residential district in Tianjin was built. Based on big data analysis,heat can be accurately supplied to each dwelling house,and a "station-load linkage" intelligent regulation strategy aiming at providing comfortable room temperature for thermal power users was established to guide the energy-saving and optimal operation of the thermal power station.On the premise of ensuring the heating quality,the strategy realizes the heating on demand,energy-saving and consumption reduction.By comparing the heating operation data before and after the optimization,it can be seen that the temperature difference between the supply and return water of the secondary network,the dispersion of the household return water temperature,the compliance rate of indoor temperature,the operation frequency of the circulating water pump,the power consumption of the circulating pump and the heat consumption per unit area changed significantly.The research results showed that after taking the secondary network intelligent balance system,the heat consumption per unit area and power consumption per unit area in this residential area were reduced by 14% and 23% respectively,and the compliance rate of indoor temperature reached 99%.Moreover,the heating quality was improved significantly while the energy-saving effect was remarkable.The study on this project can provide reference for the transformation and design of similar projects.
