长沙地铁2号线能耗分析

Energy Consumption Analysis for Changsha Metro Line 2

为降低地铁运营能耗成本,根据长沙地铁2号线试运营期间的能耗情况,分析了牵引能耗和动力照明能耗的特点,对已采用的节能技术和措施进行了综述,肯定了列车再生制动、车站空调优化控制等节能措施在实际运营中的效果,同时介绍了再生电能吸收利用系统等下一步的节能方案。

For reducing the metro operation cost,according to the energy consumption during the trial operation of Changsha metro line 2,the characteristics of energy consumption for propulsion,motive and lighting devices was analyzed,and the existing energy saving technical and measures were described.The effect of energy saving measures,such as regenerative braking of train,optimal control of air conditioning in station etc.,were affirmed in actual operation,at the same time,the next energy saving scheme such as the regenerative electric energy absorption and utilization system was introduced.
