Project Summary

Energy generation from fossil fuel may cause so many environmental problems like emission of greenhouse gasses, global warming and acid rains. Renewable energy sources play a major role in these types of situation. Renewable energy is the energy that extracts from renewable sources such as Winds, Sunlight, Rain, Tides, Waves, Geothermal heat…etc.

The popularity of renewable energy has experienced significant growth recently due to the foreseeable exhaustion of conventional fossil fuel power generation methods and increasing realization of the adverse effects that conventional fossil fuel power generation has on the environment. Wind power represents an environmentally friendly energy source without fuel cost and without gas emissions. It is an attractive and alternative power source for both large scale and small scale and distributed power generation applications.

Wind turbines are capable of producing higher power in a smaller place when the wind is blowing at a constant rate. Wind turbines can be divided into two main groups: horizontal axis wind turbines (HAWT), and vertical axis wind turbines (VAWT). The main difference between these two is the orientation of the rotational axis. Recently, vertical axis wind turbines have been receiving popularity because of its ability to rotate regardless of wind direction and easy maintenance.

The advantage of having a vertical axis of rotation is that wind can be absorbed from all directions without the need for a yawing mechanism. The blades do not require to be pitched to compensate for fluctuations in wind speed. These factors make the VAWT simpler to build and maintain than a HAWT. Also, VAWTs are generally less noisy than HAWTs. However, the VAWT is not self-starting meaning that it will not begin to rotate of its own accord. This is easily overcome by running the generator as a motor during initialization. And we will use the axial flux alternator to increase the efficiency of vertical axis wind turbine, for this we have to fabricate the axial flux alternator also using this turbine as a hybrid VAWT by placing solar with batteries.

Project Objectives

Objective 1:  To review the literature related to renewable energy and VAWT.

               First of all we will review the literature related to the project from internet and from different research papers for thorough study of the project from different aspects.

Objective 2:  To design the Axial Flux Motor.

               Axial flux Motors are not much introduced in Pakistan. In order to make our system cost effective we are designing Axial Flux Motor based on 1stator and 2 rotor structure that would be compatible with our VAWT.

Objective 3: To build up simulation based model to test the efficiency of Axial Flux Motor.

               To analyze the efficiency of the Axial Flux Motor a simulation based model will be made.

 Objective 4:  To improve the overall performance of Wind energy system by using Axial Flux Motor.

               Vertical axis Wind Energy conversion system has been under consideration for a long time but most of them are based on Radial Flux Motor, Induction Motors and other kinds of motors due to which the efficiency of VAWT are compromised. Therefore we are using Axial Flux motors to increase the efficiency at the maximum level.

Objective 5: Report Writing

               Finally we will write a Formal report of the work that we are doing.

Project Implementation Method

Implementation process will be done through these steps:

• We studied different research paper for improving our wind turbine speed.
• Designing of different parts of wind turbine on Autocad.
• We are break wind turbine into different sub small parts.
• Making of stator of VAWT because we are using axial flux generator.
• Fabrication of axial flux generator divided into sub parts.
• To develop an efficient method of generating Electrical Energy through Hybrid (Solar, Wind) energy system.
• To improve the efficiency of conventional Wind Turbine system.
• To develop an efficient design for the Axial Flux Permanent Magnet Motor.
• To implement the hybrid energy system.
• Improve the structure of the VAWT so wind losses will be less.
• Implement the simulation based VAWT in the hardware form.

Benefits of the Project

Benefits of the project are as follows:

1. we can use this project in roads or highways to reduce electricity consumption.

2. This vertical axis wind turbine can be used for power generation at low scale i.e. it’s a domestic source of energy.

3. As it is vertical in design therefore it can easily be place parallel to the road to generate power for street lights.

4. Strong supporting tower in not needed because generator, gearbox and other components are placed on the ground.

5. Maintenance workers do not have to climb as high to reach parts of the tower. Not only are VAWT’s shorter. They also have major components closer to the ground. Maintaining generators, gearboxes, and most of the mechanical and electrical parts of the structure therefor lifting equipment and climbing gear aren’t needed either.

6. Quieter to operate, so they don’t disturb people in residential neighborhoods.

Technical Details of Final Deliverable

Once the project is fully implemented and installed, it can produce energy enough to charge the 12 volts battery within a minimum amount of time and also lightning the lights if we will use in roads or streets. However, it depends on the windspeed as well. If the windspeed is lower the solar panel can supply enough power to charge the battery.

It approximately delivers enough power to households needs the energy requirement.

at the final stages we will compare the results with the simulation.
