SECTION-B
2. The maximum demand of a power plant is 40 MW. The capacity factor is 0.5 and the
utilization factor is 0.8. Find (a) Load factor (b) Plant capacity (c) Reserve capacity
(d) Annual energy production.
3. The incremental costs in Rs. Per MW-hour of two 250 MW units are as under :

The minimum load of each is 20MW. Find the load division between the two units as the
total load varies from 40MW to 500 MW.
4. An industrial consumer has a single phase 230 V supply. His monthly energy
consumption is 2020 kWh. A maximum demand indicator installed at his premises
indicates 40A which is charged at unity power factor for 2 hours daily at Rs. 9.50 per
kWh. The remaining units are charged at Rs. 7.50 per kWh. Find the monthly bill (for 30
days) and average tariff per kWh.
5. Discuss the advantages of combined working of Run-off river plant and steam plant.
6. What are the benefits of Co-generation? Discuss the various cogeneration technologies.
SECTION-C
7. A region has a maximum demand of 500 MW at a load factor of 50%. The load duration
curve can be assumed to be a triangle. The utility has to meet this load by setting up a
generating system which is partly hydro and partly thermal. The costs are as under :
Hydro plant : Rs. 7300 per kW per annum + operating expenses Rs. 0.42 per kWh.
Thermal plant Rs. 3800 per kW per annum + operating expenses Rs. 1.66 per kWh.
Determine the capacity of hydro plant, capacity of thermal plant, energy generated
annually by each and overall generation cost per kWh.
8. a) What do you mean by load forecasting? Discuss the various methods of load
forecasting.
b) Discuss the Factors which tend to limit the size of units of steam plants.
9. Explain briefly :
a) Methods of loading turbo generators
b) Organization of power sector in India
