This document summarizes a mini hydro power plant project. It describes the team members, R. Deepu Kumar and B. Karunakaran, and their course coordinator, K. Sheela Shobana Rani. It then provides details on the types and components of hydro power plants, including how they convert potential energy from water into electricity using turbines and generators. It also outlines the different classifications of hydro power plants based on size and head.

3. HYDRO POWER PLANT:
 Hydro power plants convert potential energy into mechanical
energy through water turbines , which then generate
electricity.
Hydro power is the most important and widely used renewable
source of energy.
It contributes about 17% of world total electricity production.
INDIA has about 197 hydro power plants.
Sidrapong hydro electric power station is the first hydro
electric power station in India.
INTRODUCTION

5. Layout of hydro power plant
ReservoirDam
Surge tank
Valve house
Pen stock
Turbine
Generator
Controlling unit
There are three types of
hydro electric power
plant
Based on head
Low head
Medium head
High head

6. BASED ON SIZE OF HYDRO POWER
PLANT
Types of Hydro Power Plant
 PICO HYDRO POWER PLANT
 MICRO HYDRO POWER PLANT
 SMALL HYDRO POWER PLANT
 MINI HYDRO POWER PLANT
 MEDIUM HYDRO POWER PLANT
 LARGE HYDRO POWER PLANT
Capacity
Upto 10 KW
Upto 10-300 KW
Upto 300-1 MW
Above 1 MW
15-100 MW
More than 100 MW

7. There are two types of turbines
 Impulse Turbines:
It uses the velocity of the water to move the runner
and discharges to atmospheric pressure. Its suitable for high
head, low flow applications.
 Reaction Turbines:
It develops power from the combined action of
pressure and moving water. It is generally used for sites with
lower head and higher flows than compared with the
impulse turbine.
BASED ON TURBINES

ADVANTAGE
 No operational green house
gas emmisions.
 Non environmental benifits:
 Flood Control
 Irrigation
 Transportation
 fisheries
 No fuel is required.
DISADVANTAGE
 Loss of land
 Interference with transport of
sediment by the Dam
 Climatic and sesimic effects
 Impact on acquatic ecosystem,
flora and fauna.

10.  It is one of the oldest power plant on the planet.
 It is the cheapest way to generate the electricity.
 World wide about 20% of all electricity is generated
by Hydro power plant.
 It prevents the burning of 22 Billion Gallons of oil/120
Million tons of Coal per year.
 It coverts 90% of the available energy into electricity.
 The world’s largest power plant is in china which is
1.4 miles wide and 6.7 feet height.
