本文介绍了国外电气化铁道节电工作的经济效益,分析了列车牵引总能耗的组成,说明设计省能牵引动力和省能运行、最佳驾驶是两项有效的途径。认为其中延长惰行时分、选好旅行速度和运行时分是节能的关键。当前应该加强节电方面的科研工作,制订一个整体的节电规划。 This paper introduces the economic benefits of electric railway energy saving in foreign countries, analyzes the composition of the total energy consumption of train traction, shows that the design province can pull power and save energy, and the best driving is two effective ways. It is considered that the key point of energy saving is to choose the speed of travel and the hours of operation in order to prolong idling time. At present, the scientific research on energy conservation should be strengthened and an overall energy-saving plan should be formulated.
