摘要:

用户侧室温采集是智慧能源系统实现按需供热和效果评估的重要手段和关键测量参数,但现有方法面临成本问题和局部测点安装位置选择导致的准确度问题。基于红外遥感的测温方法与实际场景相结合,探究结合红外遥感与传感器测温的综合室温测量方法,分析测温位置、气象、用户开窗行为和基准房间数量对测温效果的影响,以及该方法的优化效果并讨论其工程应用性。结论显示,当基准房间数量增加至2个后收益最高,可明显降低天气、开窗等外界干扰的影响,提高方法的鲁棒性,同时不受边际递减效益的影响,误差约在±1.5 ℃的范围内。对于基准传感器的布置优化问题,经过对比发现,边-顶组合可作为一个较好的参考位置,该方法与常规方法相比能明显降低覆盖率指标中的传感器安装要求,为未来的工程适用性提供参考。

Abstract:

User-side room temperature acquisition is an essential tool for integrated intelligent energy systems' on-demand heat supply, and room temperature is the key performance evaluation parameter for the system. However, current acquisition approaches are of excessive cost and high uncertainty caused by sensor locations. Combining the infrared remote sensing-based temperature measurement method with the actual scenarios, the impacts of sensor locations, weather conditions, users' open window behaviors and the number of baseline rooms on the temperature measurement were analyzed. Then, the optimization and applicability of the proposed method were discussed. The analysis results show that when the number of baseline rooms goes up to two, the impacts of external interferences, such as weather conditions and window opening behaviors, can be reduced significantly,and the robustness of the system can be improved. Unaffected by diminishing marginal benefits, the approach can keep the measurement error within ±1.5 ℃. As for the installation position of sensors, the edge-top combination is taken as the better choice. Compared with the conventional method, the proposed method can significantly reduce the requirements on the coverage rate of sensors, and can provide a reference for the engineering cases in the future.
