Research on the Electric Efficiency Evaluation of Subway Station Lighting System

研究目的:地铁照明系统是维持地铁正常运行的关键部分,由于其工作时间长并且能耗大,因此地铁照明节能意义重大。课题通过建立地铁车站照明系统的电效评价体系,获取对电效影响程度较深的指标,确定地铁照明系统的经济实用节能方向,是对地铁照明系统节能的决策性研究。研究结论:论文明确界定了参数集的层级框架及其关系,结合特尔菲法(Delphi)和BP神经网络法,在参数集中二次确认了评价体系的指标;再以层次分析法及拟熵值法作为分析工具,以综合赋权的方式得出地铁车站照明系统中影响电效指标的权重。整个地铁车站照明系统的电效评价体系反应了专家对于节能的趋向性意见,是对地铁照明系统能源的科学管理和可节约能源的全面分析,同时为实行节能技术改造和提高能源的利用率提供科学依据。

Research purposes： The lighting system is the key component to maintain routine operation,because of its long operation time and huge power consumption,the subway lighting energy-saving has great significant nowadays.The subject of obtains the indicators which has deeper impact on electricity efficiency and the economical practical of energy-saving direction for the subway lighting system according to the electric efficiency evaluation construction. Research conclusions：The electric efficiency parameter of metro station lighting system is extracted,the set of parameters＇ hierarchical framework and relationship are clearly defined.Combination of Delphi method and BP neural network method,the index of evaluation system are twice-confirmed in the parameter set.With the analytical hierarchy process and the qusai-entropy method as an analysis tools,the index which affected electric efficiency in subway station lighting system are empowered weights in an integrated way.The electric efficiency evaluation system of whole subway station lighting system which is reflected the expert opinion tendency about energy-saving,which is a scientific management of energy and a comprehensive analysis of energy saving,which is provided the scientific basis for technological transformation of implementation energy-saving and enhancement of energy efficiency.
