دانلود Capacitive and Hybrid Energy Storages for Metro Railcars

Abstract

In this paper the simulation models by Matlab for an urban-metro  railcar  and  some  newer  methods  for  reducing  the  need value of capacitance for energy storage are presented. The achievable decreasing ratio of the needed energy storage at SCAP is 25  to 40 % with this improved energy control method. It was been investigated the supercapacitor and the Li-ion battery as hybrid energy storage system and its effectiveness under operation of a suitable energy control system. Mass reduction of our hybrid storage system is significant.
