Quantitative Estimation of Railway Vehicle Regenerative Energy Saving: “A Case of Addis Ababa Light Rail Transit (AALRT)”

نویسندگان

چکیده

A rapidly growing demand and shortage of electric energy require mankind to efficiently use it, recuperate store it from the existing system, when possible, for further applications whenever need arises. Electric trains figure among big consumers different railway transportation services; light rail transit are characterized by frequent stoppings entrain detrain passengers. In their operation, traction drives made keep on braking in order meet service requirements between closely spaced passenger stations. The modern system used is regenerative braking, which acts as an generator during period. objective this paper estimate magnitude that can be recuperated a percentage train consumption East-West (Ayat Tolhailoch) West-East (Tolhailoch-Ayat) directions Addis Ababa Light Rail Transit. Mathematical equations have been calculate consumed stations followed quantification at each station. Considering current average running speed (24km/h) line, resulted 26.31% 28.18% respectively saved through recuperation. From above results, was observed strongly depends efficiencies inverter induction motor.

A Study of the Wear Behavior of a Rail Material

The rail track is one of the most important elements of a railway system. During the passage of trains, the rails are subjected to contact load that comes from the wheels of the train.  The railway track often fails in service due to wear caused by contact fatigue and other wear damage mechanisms that could also limit the life span of the railway infrastructure and railway vehicle. The aim of t...

Contact Force Estimation in the Railway Vehicle Wheel-Rail Interface

Increased patronage of railways in the UK in the past 20 years has put demands on rolling stock to operate at peak availability with reduced time available for maintenance. One possible tool to enable this is the use of real time fault detection and diagnosis on board railway vehicles to detect faulty components and provide information about the current running condition of the system. This pap...

Comparison of Light Rail Transit With Bus Semirapid Transit

Selection of transit modes is one of the most important decisions in the transit planning process. A particularly important decision is the selection between bus and rail modes, because it influences the type of service that will be offered and, more importantly, the role transit will play in the city. Ultimately, such a decision has an impact on the quality of life in the city. It is therefore...

The Highlight of Growing Light Rail Transit

Light Rail Transit (LRT) is a kind of rail vehicle form which includes from modern tramcars to speed transport. These vehicles go on special road, underground, floor or specific altitude. Today the number of active serving LRT systems in 50 countries is more than 400. Moreover, a forceful increase has been expected for next years. It is clear that this growing up has certain reasons. In this st...
