            摘要:

            隨著地鐵車站用電量的不斷增長,有必要對其用能主要項建立能耗指標,對其運行現狀及節能措施進行評估和研究?;诘罔F車站各主要用能系統的運行特征,建立了詳細的分項能耗原理模型,包括通風空調、照明和垂直交通系統。該模型可以通過輸入車站的建筑和運營狀況,對各分項用能系統的合理能耗進行詳細計算??紤]到數據收集工作量大的問題,為了滿足實際工程應用的需要,進一步通過敏感性分析提取了能耗模型的重要輸入參數,探究了模型的簡化。簡化的通風空調系統和垂直交通系統能耗模型的均方根誤差變異系數分別為7.6%和7.4%,符合工程應用的精度要求。簡化模型的提出降低了工程中數據收集工作的難度,可以實現將能耗模型在全國不同氣候區各城市地鐵車站中進行大規模應用,快速評估車站的運行狀況和節能潛力。

            Abstract:

            With the continuous growth of electricity consumption in underground railway stations, it is necessary to establish energy consumption indicators for major energy use systems to evaluate the energy consumption level and energy saving potentials. Based on the operating characteristics of the major energy use systems of underground railway stations, develops the sub-system energy models, including ventilation and air conditioning (VAC) model, lighting (LIGHT) model and vertical transport (TRANS) model. With the help of these models, the reasonable energy consumption of each sub-system can be simulated by inputting construction and operation status of the underground railway station. Furthermore, taking into account the large workload of data collection in practical engineering applications, extracts the important input parameters of the sub-system energy models using sensitivity analysis, and studies the simplification of the models. The results show that the CV-RMSE of the simplified VAC and TRANS models are 7.6% and 7.4%, respectively, which are acceptable for engineering application. The proposed simplified model greatly reduces the difficulty of data collection in actual projects. Therefore, it is easy to be used in the large-scale application in more underground railway stations across the country to quickly evaluate the operating conditions and assess energy saving potential of underground railway stations.
