Sample EE6801 Question Bank:

1. (i)Describe the series- parallel control of electric traction motor. Also specify the advantages of the above control.(8) (EE6801 Question Bank)

(ii)A train runs with an average speed of 50 kmph.Distance between stations is 4.5 km. Values of acceleration and retardation are 1.5 kmphs and 1.8 kmphps respectively. Calculate the maximum speed of the train assuming a trapezoidal speed time curve.(8) (EE6801 Question Bank)

2. (i)Explain the recent trends in electric traction systems(8) (ii).A sub urban electric train has a maximum speed of 65kmph.The schedule speed including a station stop of 30seconds is 43.5kmph.If the acceleration is 1.3kmphps; Identify the value of retardation when the distance between stops is 3km.(8)

3. (i)Explain about the types of supply system used in traction system.(8) (ii) A 250 tonnes train with 10% rotational inertia effect is started with uniform acceleration and reaches a speed of 50 kmphps in 265 seconds on level road. Calculate the specific energy consumption if the journey is to be made
according to trapezoidal speed- time curve. Acceration = 2 kmphps; Tracking retardation = 3 kmphps ; Distance between the stations = 2.4 km ; efficiency = 0.9; Track resistance = 5 kg/tones.(8) (EE6801 Question Bank)

4. (i)With the aid of transmission of tractive effort, describe the mechanism of train movement.(8) (iiDescribe clearly regenerative braking when used for Dc series traction motors. Also discuss the requirements for ideal traction.(8)

5. (i)A sub urban electric train has a maximum speed of 65kmph.The schedule speed including a station stop of 30seconds is 43.5kmph.If the acceleration is 1.3kmphps; Calculate the value of retardation when the distance between stops is 3km. (8) (ii)Discuss short notes on Trolley bus.(8) (EE6801 Question Bank)
