• Hydroelectric power plant: Selection of site–
Hydrological cycle / flow measurement –
drainage area characteristics – Hydrographs –
storage and pondage – losses due to percolation,
evaporation and transpiration-General layout of
the plant- classification-low, medium and high
head plants pumped storage plants-Typical
layouts – plant auxiliaries – plant operation- spill
ways-Mini and micro hydel power plants
,• The potential for Hydroelectric power in India
is 145300 MW,
• Installed capacity of hydroelectric power in
India is 45699 MW
, Advantages and disadvantages of hydroelectric power plant
Advantages
• 1. No feel requirement
• 2. Low running cost
• 3. No problem of ash disposal
• 3. Pollution free electric generation
• 4. easily switch on and off in a short period
• 5. Greater expectancy of life
• 6. Ancillary benefits: irrigation, flood control, aqua culture.
• 7. Less skilled workers
• 8. Quick response to the change of load
Disadvantages
• High capital cost, power dependent on quantity of water
available, site selection dependent on water availability, long
erection time, disturbed ecology of the area.
, Site selection for hydroelectric power plant
• (i) Availability of water, (ii) Water
storage capacity,
(iii) Available water head, (iv)
Accessibility of site, (v) Distance
from the load centre, (vi) Type of the
land on site, (vii) environmental
aspects,
(Viii) sociological aspects.
