HYDRO POWER PLANT
 The hydro power plant play very important role in
development of the country as it provides power at cheapest
rate as source of natural energy
 About 20% of power of the total world power is generated
by hydropower station
 The main source of hydroelectricity is the water which is the
readily available in india
MAJOR APPLICATIONS OF HYDRO
POWER PLANT
 The controll the floods in the river
 To produced electricity
 To store the water for irrigation
 To store the drinking water
 To supply a drinking water
 Small hydro power plant is used for serving a small
community or industrial plant
 Micro hydro power plant is used to provide power to an
isolated home
PRINCIPAL OF GENERATION OF
HYDROPOWER
 The water of hydrolic turbine converts kineticenergy in to
the potential energy in mechanical power and is thus a prime
mover which couple to a generator,produced electrical
power the power plants designed to produced electrical
power from water,flowing continuously under pressure are
known as “HYDRO ELECTRIC POWER PLANTS”.
COMPONENTS OF HYDRO ELECTRIC
POWER PLANT
 Catchment area:it is the whole area behind the dam.
 Reservoir:to store the water during rainy season and supply
the water during dry season.
 Dam:a dam built across the river.it increase the working head
of the power plant
 Trashrack:to prevent the entry of a debris which might
damage the fixed blades and runner of turbine.
 Forebay:this are a kind of storage tanks which are present at
end of the head race pipe.
 Surge tank:it provides better regulation of water in the
system during variable load conditions.
COMPONENTS OF HYDRO ELECTRIC
POWER PLANT
 Penstock:to carry water under the pressure from the large
reserviour to the turbine.
 Slipway:to discharge major floods without damage to the
dam and same time keep the reserviour level below
predetermine maximum level.
 Turbine:to converts kinetic energy in to mechanical energy
and produced electric energy
 Electrical generator
 Power house
 Draft tube
SITE SELECTION FOR HYDRO
ELECTRIC POWER PLANT
1) Availability of water
2) Water storage
3) Water head
4) Catchment area
5) Availability of a water and type of land
6) Accessibility of the site
7) Distance from load centre

According to availability of head
Low head plants:when the head of water available is less
then 50m,the power plant is called low head plant .in this
plant generally francis,propeller or kaplan turbine used as
a prime mover
Medium head plants:when available head usually lies
between 50m-300m the plant is called medium head
plants. In this power plant francis ,propeller,or kaplan
turbine are used
High head plants:when available head is usually greater
than 300m its used infrancis and pelton wheel turbine.
CLASSIFICATION OF HYDROELECTRIC
POWER PLANT
 According to the quantity of water
available
 Run off river plant
 Run ofn river plant with reserviour
 Storage type plants
 Pump storage plants
 Mini and micro hydro plants
CLASSIFICATION OF HYDROELECTRIC
POWER PLANT
 According to nature of load
 Base load plants
 Peak load plants
ADVANTAGES OF HYDRO ELECTRIC
POWER PLANT

5.
the operating cost of hydroelectic plant is less compare to
thermal and other power plant
The cost of power generation of hydro electric power plant
is not affected by the load factor
Yhere is no requirement of a fuel
Less mechanical problem and no required any special
material for construction of plant
The life of hydroelectric power plant is 100-125 year of
thermal power plant.
DISADVANTAGES
the investment cost of hydroelectric power plant much
more than thermal power plant
2. Power generation by hydro electric plant depends on water
availability which depends on natural phenomenon of rain
3. The side of hydroelectirc plant is selected where water
availability at economical head
4. Time required for construction of plant is much more than
thermal power plant
