CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
This project was the second major project in my electrical engineering career. Small
wind turbine can be defined as the specific wind turbine that is being utilized for the micro
generation as being opposed to the larger commercial wind turbines. These are majorly found
in the wind farms with high output of individual power. The significant range from less than
1000 watt or 1 kW eventually turbines up to around 300 kW. During this project, I designed
and fabricated the small wind turbine for the purpose of generating power. I investigated that
the smaller scale turbines have their blades usually from 1.5 meters to 3.5 meters in diameter
and noticed that around 1 to 10 kW of electricity is being produced at the optimal wind speed.
Some of the units are subsequently designed for being extremely lightweight and hence
enabling sensitivity to the smaller wind movements as well as the rapid response to wind
gusts. In this particular project, I have undertaken the savonious wind turbine for designing as
well as generating power. I had to design an exhaust fan in my project, since I work in

commercial kitchen. I implemented safety precautions within the site and then developed
healthier atmosphere by the proper enforcement of rules, regulations and procedures.
Therefore, I have researched and documented the design and fabrication of a smaller wind
turbine with the type of vertical axis and having a potential to generate power. Moreover, in
this project work, I have taken the blade shape as spiral involute.
CE 2.2.2 Objectives developed for the project
Small wind turbine with vertical axis comprises of the main rotor shaft that eventually
run vertically. The most significant advantage of this type of turbine is that the gearbox and
the generator could be easily placed at the bottom and this helps the turbine in not requiring
any support from the wind. While working on this project, I have identified that the spiral
involute shape of the turbine blade is required for the proper power generation. Therefore, in
order to complete my project and generating power by designing a small wind turbine, I have
developed the following objectives:
 To propose a design for the small wind turbine with the help of designing software.
 To identify the correct shape of our turbine blade.
 To set up the experiment to be undertake by me and my team.
 To determine size and efficiency of the smaller wind turbine for providing perfect
output to the project.
 To receive external electrical connections from the project and utilize this in
designing the exhaust fan.
 To generate power with the help of my designed smaller wind turbine.
 To check the results with the by comparing with the other experiment results.

CE 2.2.3 My area of work
I had been appointed as an electrical engineer in this project. Since, I had to design a
small wind turbine within the exhaust fan, I researched and studied several books, conference
papers, journals and past researches, which are absolutely relevant to the vertical axis
savonious wind turbine. As I was experienced in electrical projects and had executed some of
the most important projects in my engineering career, I investigated that the savonious wind
turbines are considered as of the simplest and most utilized turbines that consists of a
savonious wind rotor. I even checked that the savonious wind rotor is one of those vertical
axis wind turbines. I also provided significant suggestion to use the spiral involute shape of
the turbine blade for getting a better solution during the generation of power. Moreover, I was
also responsible for checking the power required in this project, which was of 300 kW and
even carried out the significant experimental investigation to study about the vertical axis
wind turbine or savonious wind turbine. My other area of work was to calculate the design
results of my exhaust fan in each and every dimension. Being a skilled electrical engineer, I
even assisted my project leader in this project.
