Electric Traction

  1. 1. TRACTION Driving forward of vehicle is called traction and the system, which employs this type of mechanism is called Traction system. Classified broadly into groups namely: Non-Electric traction system. Electric traction system.
  2. 2. The system which use electrical power for traction system i.e. for railways, trams, trolleys, etc. is called electrical traction. OR  Electric traction means a location in which the driving force is obtained from electric motors.  Electric traction will continue to play a dominant role in the railways since it is an environmentally clean technology compare to diesel traction and also its running cost is low.  There are many advantages of electric traction over other forms of locomotion. 
  3. 3.  Maximum traction efforts should be exertion at starting in order to have rapid acceleration.  Equipment should be capable of overloads for short period .  The wear caused on the track should be minimum.  Braking should be possible without excessive wear on the brush.  Capacity of withstanding voltage fluctuation and temporary interruption of supply.  Parallel running usually more than one motor (two or four) should be possible.
  4. 4. Cheapness : It is cheapest method if all methods of traction. Cleanliness : It is free from smoke and flue gasses. Maintenance cost : Maintenance and repair cost is about 50% of steam traction system. Starting time : It can be started without loss of time. High starting torque : This system uses of D.C & A.C series motor, which has a very high starting torque. Braking : In electric traction, regenerative breaking is used which feeds back 40% of the energy. Saving in high grade coal : No coal is required for electric traction.
  5. 5. o o o o o High initial expenditure. Failure of supply is a problem. Electrically operated vehicles have to move only on electrified track. For braking & control, addition equipments required. Interference with telegraphs and telegraph lines.
  6. 6. D.C. system. II. A.C. system. i. There phase A.C. system. ii. Single phase standard frequency system. iii. Single phase low frequency system. iv. Single phase to three phase system [kondo system]. e.g:600v dc is given to tramways and trolley buses. I.
  7. 7. In general following electric system exist:  AC 3 phase 3.7 kV system.  AC single phase 15/16 kV-161/25 Hz.  AC single phase 20/25 kV-50/60 Hz.  DC 600 V.  DC 1200 V.  DC 1.5 Kv.  DC 3 Kv.
  8. 8. Advantages: 1. Light overhead catenary. 2. Saving in sub-station. 3. More flexibility. 4. Lesser equipment used & easy to maintain. 5. Starting efficiency. 6. Cheap as far as cost for fixed installation. Disadvantages: 1. Single-phase A.C. system imposes unbalancing effect 2. Produces interference with telecommunication lines.
  9. 9. THYRISTOR CONTROL Scheme of AC Electric locomotive power system with Thyristor control and separately excited DC motors.
  10. 10. HOW IT DRIVES
  11. 11. With AC Motor Traction With DC Motor Traction
