摘要
高速公路隧道照明在不同管控策略下能耗差异较大,当前无极调光模式下动态变化因素较多,导致测算照明能耗比较困难.为量化研究公路隧道运营过程中采用智能无极调光控制系统时的能耗水平,提出了一种基于季节、历史天气和实时洞外亮度的能耗计算模型.首先分析了公路隧道照明设计现状与不同天气工况下的调光控制策略,为公路隧道照明的能耗计算提供理论支撑;其次构建了基于季节、历史天气预测和单日实时洞外亮度变化的能耗计算模型,并以贵州省在建小寨隧道为例测算了能耗情况.结果表明,基于季节、历史天气统计与洞外亮度等因素测算的能耗能更加真实有效反映智能无极调光系统的实际运营状况,为运营管理单位实时调整照明控制策略与节能升级改造提供重要的参考依据.
Abstract
The energy consumption of highway tunnel lighting varies greatly under different control strategies,and there are many dynamic changes in the current infinite dimming mode,which makes it difficult to calculate the lighting energy consumption.To quantify the energy consumption level when using an intelligent stepless dimming control system during the operation of highway tunnels,this paper proposes an energy consumption calculation model based on season,historical weather,and real-time brightness outside the tunnel.Firstly,the current status of highway tunnel lighting design and dimming control strategies under different weather conditions were analyzed,providing theoretical support for energy consumption calculation of highway tunnel lighting.Secondly,an energy consumption calculation model was constructed based on seasonal and historical weather forecasts,as well as real-time changes in brightness outside the tunnel on a single day.The energy consumption situation was calculated using the Xiaozhai Tunnel(1 297 m/1 292 m)under construction in Guizhou Province as an example.The results indicate that energy consumption calculated based on seasonal,historical weather statistics,and outdoor brightness factors can more accurately and effectively reflect the actual operation status of intelligent stepless dimming systems,providing important reference basis for operation and management units to adjust lighting control strategies and energy-saving upgrades in real time.
