Question Paper
1. Choose the correct answer from the given alternatives
The load of a system is shown in the following figure
<img src='./qimages/13268-1a.jpg'>
Load factor for the period 6 -24 hours period is
0·438
0·50
0·876
1·00
Which meter is installed at the premises of a consumer for recovery of charges of electrical energy
Voltmeter
Ammeter
kVA meter
kWh meter
Which equipment provides fluctuating load?
Lathe machine
Exhaust fan
Welding transformer
All of the above
The capital cost per MWh is highest in case of
steam power plants
diesel engine power plants
nuclear power plants
hydroelectric power plants
A steam power station will run with maximum efficiency when it is run
at low steam pressure
on pulverized coal
at higher speeds
near full load
In case of medium sized induction motor, the power factor will be maximum at
No load
50% load
Full load
Power factor remains constant at all loads
The power factor of a system on a 460 3-phase, 60 Hz, in which the ammeter indicates 100 amp and the wattmeter reads 62 kW will be
0·95
0·74
0·65
0·55
2. Explain the two-part and three-part tariffs and give -the economic basis for adopting the above tariffs.
3. Discuss the factors affecting the economics of generation of power and how one can reduce the cost of power generation.
Discuss the economic loading· of combined steam and hydro plants.
What is the importance of diversity factor and load factor and how do they influence the cost of generation
5. Explain the paramagnetic and zirconium sensor in respect of gas analysis.
6. Determine the thermal efficiency of a power station and its coal bill per annum from the following data:
Maximum demand: 20 MW
Coal consumption: 0·54 kg/kWh
Load factor: 50%
Calorific value of coal 6400 kcal/kg
Price of coal RS 500 per tonne
7. Discuss the methods used for coordination of incremental fuel cost and incremental transmission loss in the economic loading studies of power plant.
8. Write short notes on any two of the following:
Furnace Draft Control Method
Unit Commitment
Subsidization and Cross Subsidization
