2. Aim of Project
Aim:
• The main aim of this project is to build a Hybrid Power Plant that
uses Renewable Energy Sources (Wind and Solar Energy) to produce
Electrical Power.
• This types of Arrangment make with the help of Combination of V.A.W.T
And Solar Panels .

3. Problem Specification
• The project has been designed to solve the problem of the unavailability of
electricity to the remote areas which are off grid and also to use it for peak
load sharing with the Thermal Power Plants.
• Hence, this project has been made with an aim to design a hybrid power
plant that uses renewable sources of energy to produce electricity.
• By using the hybrid power plant, we can get uninterrupted, reliable,
environment-friendly power, at an economical rate.

4. Plan of Work
• A hybrid power plant has been designed, which uses Wind energy and Solar
energy for generation of electricity.
• The V.A.W.T. generates Ac voltage (9 v) and with the help of rectifier converts
Ac into Dc voltage in the range of 12. 5 to 14.5 Volt.
• The Solar module generates D.C. voltage of 5.1 V, at the time of full sunlight.
• And this two sources combine with the help of switch assembly and given
supply to Dc Motor.
• If Ac voltage required to use inverter.

7. Mode of Operation
Case-1:
• The power from either the V.A.W.T. or the solar module can be fed to the load
as per requirement
• If the V.A.W.T stop due to absence of wind this time solar module is use .
• And also one Important facility to provide by V.A.W.T is If load demand is not
more so generate power store by Battery bank.
Case-2:
• If power demand is high this time combine power of V.A.W.T And Solar
module is use, with the help of Switch Assembly

12. Advantages And Disadvantages
Advantages:
• Solar and Wind is a renewable energy , And it is Easily Available by the Nature.
• Environmental Friendly.
• Accepts wind from any angle - no yaw mechanism and downward coning
required.
• Reliable .
• Virtually silent operation.
• High Mechanical stability.
• Ease of Operation.
• Components can be mounted at ground level. P.T.O

13. Disadvantages
• Initial Cost is High.
• One of the major outstanding challenges facing vertical axis wind turbine
technology is dynamic stall of the blades as the angle of attack varies rapidly.
• The majority of the disadvantages associated with VAWT technology have
been overcome by the use of modern composite materials and
improvements in engineering and design

14. Application
• Government.
• Educational Body.
• Power plant.
• Big industries.
• Small Villages.
• Environment clearances.
• Availability of a distribution sub-station connection
connected to the electrical grid, within a short distance.
