Actual name of the topic
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.
