HYDRO ELECTRIC POWER PLANT: 
1 Components Of Hydro Electric Power Plant 
2 Working Principle Of Hydro Electric Power Plant 
3 Classification Of Hydro Electric Power Plant 
Reservoir : 
Water is accrued in the long run of moist season 
• 
It is stored withinside the reservoir. 
• 
A dam is built sooner or later of the river accurate sufficient water head. 
Penstock : 
• It is a passage thru which water flows from reservoir to turbine. 
Surge Tank : 
• 
It is set up along the penstock (amongst turbine and reservoir) 
• 
To manipulate or alter the unexpected water over go with the flow and to guard the penstock from bursting. 
• 
It reduces the strain and avoids damage to the penstock due to the water hammer effect. 
• 
When the load on the turbine is decreased there may be a all over again go with the flow, which motives boom or decrease in strain. It is known as water hammer. 
• 
Power House : 
• 
It is building that houses that water turbine, generator, transformer and manipulate room. 
• 
Water Turbine: 
• 
Water turbines which incorporates Pelton, Kaplan and Francis are used to convert strain and kinetic power of flowing water into mechanical power. 
• 
Draft Tube: 
• 
It is installation to the hollow of the turbine. 
• 
Tailrace: 
• 
It refers to the downstream diploma of water discharged from turbine. 
• 
Generator : 
• 
It is a tool used to convert mechanical power into electric powered powered powered power. 
• 
Step up transformer: 
• 
It converts the Alternating Current (AC) into immoderate voltage contemporary suitable for transmission. 
2 WORKING PRINCIPLE
• 
It uses the cappotential power of water of water stored in a reservoir. 
• 
The water from the reservoir thru a penstock and then forced thru nozzle or nozzles in advance than accomplishing the turbine. 
• 
The hydraulic turbine converts the kinetic power of water beneathneath strain into mechanical power. 
• 
The shaft of the turbine is coupled to a generator that generates power 
• 
The power generated is fed to the step-up transformer to boom its voltage. 
• 
Power is fed to the transmission lines for distribution. 
• 
The output power of Hydel power plant is based completely upon at the top of water stored withinside the reservoir and the quantity of water discharge. 
Factors to be considered for the area of hydro electric powered powered powered powered Power 
Availability of Water: 
Adequate water ought to be available with precise head.

Merits of Hydro Electric Power Plant:

 •         Requires no fuels and hence pollution free.

 •           Low operating cost.

 •           Simple in construction and requires less maintenance.

 •           Skilled personnel is required for construction
