Diesel vs electric traction pdf
Electric Locomotive vs Diesel Locomotive The major advantage of the electric locomotive engine over diesel engine is that electric engine uses a rather simple and straightforward technology. The electric engine pulls power directly from the power grid and requires only a transformer and a regulator to bring down the power to acceptable levels.An electrodiesel locomotive (also referred to as a dualmode or bimode locomotive) is powered either from an electricity supply (like an electric locomotive) or by using the onboard diesel engine (like a dieselelectric locomotive). For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose. diesel vs electric traction pdf
Characteristics of electric traction The main advantage of electric traction is a higher powertoweight ratio than forms of traction such as diesel or steam that generate power on board.
Economics of Electric vs Diesel Traction on account of fuel cost is evaluated based on the rupees spend towards energy bill for hauling 1000 GTKM of load. The trend of electrical and diesel energy cost in terms of unit charges and Rslitre as compiled in the Edit1: Please note that speed of Steam Locomotives is lesser than that of diesel electric ones. So without considering a secondary drivetrain, the generated torque of a stam engine of a Locomotive is much more than the torque generated by the traction motor of a dieselelectric locomotive. diesel vs electric traction pdf AC Traction vs DC Traction. AC TRACTION. The AC (alternating current) Drive, also known as Variable Frequency Drive, has been the standard in industry for many years. it has only been recently that the price of the drives has allowed them to be used in most of the new dieselelectric locomotives in the United States. The AC drive works by
The use of a diesel engine frees the locomotive from being coupled to an external electricity supply, and the use of electric motors and drives allows control over the traction capabilities of the locomotive which would not be possible with a direct drive from the diesel engine. diesel vs electric traction pdf Economies of Traction Diesel vs. experienced by transit commuters and outdated criteria for other Electric. 1999. toxic airborne compounds must be considered. Kleinman, Michael T. While the diesel commuter rails maximum speed is figured at 79 miles per hour, according to the report, the electric commuter rail could reach 100 miles per hour the maximum speed that can By electric traction is meant locomotion in which the driving (or tractive) force is obtained from electric motors. It is used in electric trains, tramcars, trolley buses and dieselelectric vehicles etc. DIESELELECTRIC LOCOMOTIVES INTRODUCTION When the traction motor cutout switch is open, the main power switches are open and dieselelectric locomotive, to know how to maintain them to avoid major breakdown of equipment, and to makeRating: 4.59 / Views: 514
