Revisiting energy efficiency increasing in Underground

[摘要] Underground is one of the most important means of transport in big cities. Due to the constant increasing numbers of vehicles, it turned out that in cities with populations over 1 million only underground is able to solve the problem of mobility. Besides a number of positive qualities, underground has a significant disadvantage - high power consumption. There are several methods of its power consumption decrease. One of the most efficient is the usage of energy storage devices in underground system. The aim of this article is to compare different methods of power consumption decreasing, to choose the best type of energy storage device placing and prove it by calculations.
