What is electric traction system explain its major components?
Main components of electrical traction systems: electric power sources, traction power substations and tractive engines. … Dimensioning of the stable traction power substations. Influences of the two-phase traction substation connections on the unsymmetry in the three phase power system.
How does a traction converter works?
Traction Converter would have multiple line converters which convert single phase AC input to a stable DC link bus voltage. A combination of one or more inverters converts this DC bus voltage to 3-phase power controlling one or more traction motors each.
What is electric traction?
Introduction: 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 diesel-electric vehicles etc.
What are the different components of tractive effort?
- the adhesion between the rail and the wheels being braked, and.
- the normal reaction of the rail on the wheels being braked (and hence on the weight per braked wheel)
What do you mean by traction system?
The traction system is a component of the train. It is a system installed on the roof or underneath the train. The traction system converts the electrical energy, collected from the catenary via the pantograph, into mechanical energy, thus enabling the wheels to turn and, therefore, the train to accelerate and brake.
What are the major requirements of good traction system?
Ideal traction system should have capability of developing high tractive effort in order to have rapid acceleration. The speed control of the traction motors should be easy. Vehicles should be able to run on any route, without interruption. Equipment required for traction systems should be minimum with high efficiency.
Do trains run on AC or DC?
Railways and electrical utilities use AC for the same reason: to use transformers, which require AC, to produce higher voltages. The higher the voltage, the lower the current for the same power, which reduces line loss, thus allowing higher power to be delivered.
