MICROHYDEL POWER GENERATION SYSTEM FROM

BUILDING ROOF RAIN WATER FLOW TO POWER

AC / DC LOADS WITH BATTERY REVERSE CHARGE

PROTECTION

Electricity is a basic form of energy of nature which is most widely used

forms of energy.

MOTIVATION

Energy in India? It is a big problem which is faced by people who reside in the

country

An innovative ideaThe idea is simple, by using the Micro Hydel system

which uses the roof rain water in rainy season and

generates electricity by small turbine blades connected

to geared DC generator

What Is Hydel system ?

WHAT HAPPENS ??

HYDRO ELECTRIC DAMS

TYPES OF HEADS IN HYDRO ELECTRIC DAMS

Generally there are three types of heads. They are-

1.High head ( >300m )2.Medium head ( 100-300m )3.Low head ( <100m )

Power Generation Capacity and type of hydro power plantT

Generally Microhydel power plant generates about 1000W

TYPES OF TURBINES IN THE HYDEL SYSTEM

Pelton Wheel

Kaplan wheel

Type of turbine used here is…..tle

Pelton Turbine

Procedure of Hydel system Power Generation

1. Catchment area ( The area for collecting rain water )

Procedure cont…2. The collected water is sent

through the pipes connected from the top of the building through the turbine blades.

3. These blades rotate the geared DC generator and battery is charged from it.

4. The charged battery is connected to the inverter circuit and 220V AC is obtained.

Voltage and Current ratings

Input:From DC generator12 V DC voltage (1A – 7A) current

Output:From inverter220V AC voltage (50Hz)(3A-5A) currentOutput Power: 1000 WATTS

Battery :For chargingType: Dry Voltage: 12VAmp : 7AHr

LAY OUT DIAGRAM

DISADVANTAGES

1. NO RAIN, NO WATER STORAGE, NO

POWER!!

2. MAINTAINENCE IS REQUIRED TO CLEAN

UP THE PIPES .

3. EFFICIENT GENERATION IS ONLY

POSSIBLE IF THE HEAD IS VERY HIGH

ie.., TALL BUILDINGS

ANOTHER FORM OF ENERGY …SOLAR

REMEDY

Solar Panel Rating Input :Solar Radiation ExposureAll exposed roofs shall have

a maximum U-factor of 0.261 W/m2

Understanding the value of ‘U’• The U-factor is the overall heat transfer

coefficient that describes how well a building element conducts heat.

• It measures the rate of heat transfer through a building element over a given area under standardised conditions.

• The usual standard is at a temperature gradient of 24 °C, at 50% humidity with no wind .

• SI units of W/(m²K)

COMBINATION OF SOLAR AND MICRO HYDEL

CONTROL UNIT AND LAYOUT

Reverse Charge Protection

Micro hydel is a primary source of energy in India especially in the southern regions. Promoting renewable energy sources for energy requirements in conjunction with alleviation of rural poverty, diversification of energy resources as well as economical growth towards greater sustainability, as well as environmental and social stability.
