Question Paper Code B3355
(AUTONOMOUS) M. Tech I Semester Regular Examinations, January 2018
(Regulations: VCE-R15) ENERGY CONVERSION SYSTEMS
(Power Electronics and Electric Drives) Date: 08 January, 2018 FN
Time: 3 hours
Max Marks: 70
Answer any FIVE Questions
Each Question carries equal marks
1.
Explain photo current and load current with necessary equations.
7M
Briefly explain the performance of a practical solar cell.
7M
2.
Explain the basic principle of MHD generation.
7M
An MHD duct has an inlet pressure of 10atm. and discharges into the atmosphere. Find its volume for a length of 20m and inlet diameter of 2m, if the duct is of circular cross section throughout, as well as the outlet diameter.
7M
3.
Explain the various properties of wind and air.
7M
Explain the types of wind turbine.
7M
4.
Explain the characteristics of turbines for tidal power generation.
7M
A tidal power station has installed capacity of 2176MW in 64 units each of 34MW rated output. The head at rated output is 5.52m. The embankment is 4 miles long=6.4km. Again assume 93% efficiency for both turbines and generator. The generation is 5 hours twice a day. Calculate:
i. The quantity of water flowing through each turbine and the total flow out of the tidal basin
ii. The surface area of the reservoir behind the embankment and the wash
iii. Energy produced in TW-h per year
7M
5.
Explain the principle of conversion of wave energy. Briefly explain open cycle and closed cycle OTEC system.
7M
Discuss the power content in waves.
7M
6.
Explain the energy conversion process from geothermal energy.
7M
Explain the principle of biomass conversion.
7M
7.
Explain the environmental effect of energy conversion system.
7M
Discuss the global energy position.
7M
8.
Discuss the pollution from coal and explain the preventive measures.
7M
What are the different classes of batteries?
7M
