Abstract
Regenerative braking system is a system which converts mechanical energy to
electrical energy during braking action. It is an important system for the vehicle such
as hybrid and electric train. This paper which mainly concerned about the potential of
regenerative braking system on the reduction of energy consumption.
This study will start with literature review about the Regenerative Braking System
(RBS). The important components used in RBS will be determined such as electric
motor, motor controller and pantograph.
The methodology used to creating the simulation of the regenerative braking system
at different positions of the track levels of stations of the East-west line of Addis
Ababa LRT by using MATLAB software.
In general regenerative braking system generates a reusable energy about 3.7% of
the consumed energy of the system in the east-west line with in 22 stations and five
of the stations are elevated. This energy can be generated in one tripe of the train
movement from Ayat to Tor-hayloch.
