电气节能技术在地铁车站供配电与照明系统中的应用研究

以某市地铁为例进行车站供配电与照明系统能耗分析，对车站供配电与照明系统节能措施进行了研究。研究结果表明，照明功率密度值是否满足节能标准，会对整个照明系统耗能高低有直接影响。在进行地铁车站的照明系统选择和供配电的设计过程中，将首要选择更加节能环保的照明措施和设备，在达到了相应的地铁车站的照明标准后，可以使用LED等作为照明光源。通过优化车站照明控制系统，在地铁车站中引入自然光，不仅可以达到室内照明标准，满足照明需求，还可以最大限度地降低照明设备消耗的能源，同时还能为自然通风状态创造相应条件。

Application study on electrical energy saving technology in power supply and distribution and lighting system of metro station

Taking a subway as an example，the energy consumption analysis of station power supply and distribution and lighting system was carried out，and the energy saving measures of the station power supply and distribution and lighting system were studied.The results showed that whether the lighting power density meets the energy-saving standard will directly affect the energy consumption of the whole lighting system.In the process of lighting system selection and power supply and distribution design of subway station，more energy-saving and environmental protection lighting measures and equipment will be the first choice.After reaching the corresponding lighting standards of subway station，LED can be used as lighting source.By optimizing the station lighting control system and introducing natural light into the subway station，it can not only meet the indoor lighting standard and meet the lighting demand，but also minimize the energy consumption of lighting equipment，and create corresponding conditions for the natural ventilation state.
