This report presents the whole process and all the results of the wind turbine lab, data calculations and results discussion.Wind turbine lab including the use of two software,which are very vital in the wind energy industry, Bladed and Matlab. Almost all the data in this report are calculated by Bladed , and then imported to Matlab for more accurate digital image. There will be a lot of data and diagram related to the wind turbine,curves figure and some data figure (tip speed ratio,electrical power, rotor speed generator speed,etc).All of them are key concepts for the course.Why pitch regulation? How does it work?Why variable-speed? How does it work? And which turbine is it? Getting close to the answers to the questions through curve producing , data calculating and results discussing . Comprehending more about those key concepts and understanding more about the principle of the Wind Turbine is the point of the whole process.

Wind energy has experienced a positive growth globally as an alternative source of energy (Thresher & Robinson, 2008). Also, it has been used for supplying the deficiency energy needed after the other forms of energy. Globally through innovation and invention, the wind energy has been used as a safe energy. It’s forecasted that the wind energy in the future will supply a significant amount of energy that is required globally. Through technological advancements, this growth of the wind energy is forecasted to continue. Wind energy is harnessed through the use of wind turbines that are used for the production of the energy. The presence of areas in the world that experience strong winds, the wind energy can be harnessed easily through the

Although the use of wind energy backs to more than hundreds of years (the wind wheel of Heron of Alexandria in the first century AD is the earliest known instance of using a wind-driven wheel to power a machine (Drachmann, 1961; Lohrmann, 1995)), it is yet an immature and growing technology. In recent years, coastal and offshore wind turbines are growing fast, as an attractive means for clean energy production. Due to the nature of the wind in offshore regions, that are powerful and more uniform than inland winds, offshore wind turbines can produce energy effectively (Musial and Butterfield, 2006). It should be noted that the extracted energy is proportional to the cubic of the wind speed which means an increase in wind speed has a significant influence on the amount of produced energy. In addition, it is more cost effective to place

We are facing an energy crisis on Earth. Burning fossil fuels are harming the atmosphere; this global warming and affects produces chemicals that hurt our body. People are starting to think about using alternative energy. Wind power would be our first choice, because it’s clean, inexhaustible and renewable. Today, wind power is mainly used in Europe. We believed wind power would be the main source of alternative energy for world use.

Since 1980’s wind turbines have noted a remarked progress making the whole sector and technology mature in order to enable the rapid growth on the market. This is justified by Fig.3 where it is observed that from 1996, the growth is steadily increased till 2012 and is still growing. From then till now, the cost

It gives me deep pleasure in acknowledging the valuable effort extended to me by various personalities in completion of my project because every project needs inspiration, guidance and help at every step. For this, I would like to thank Dr. Lakhwinder Singh, Head of department, for giving me opportunity to work under Dr. Fulbagh Singh, Department of Commerce, Guru Nanak Dev University, Amritsar. I offer heartfelt gratitude to Dr. Fulbagh Singh for his keen interest, suggestions, extreme support and invaluable guidance during the course of this project.

Wind turbine is a device that converts kinetic energy stored in wind to electrical energy using electrical generator. Before invention of electricity Windmill was used to convert energy of wind to rotational mechanical energy. In history we have seen many kind of drag and/or lift type of wind turbines. Currently mostly used wind turbines are three bladed Horizontal axis Wind turbine and Darrieus(or Egg-beater) type wind turbine. Majority of the modern wind turbine have can generate electrical power of 1.5 to 5MW [2]. We can define capacity factor as ratio of total wind energy extracted within a year to the total theoretical maximum power of a given wind turbine. Capacity factor depends on many factors but one on them is very low wind speed which is not enough to run a wind turbine. Wind speed increases at higher altitudes from the earth surface. Thus more energy can be extracted from the wind at high altitudes and in addition to that we have higher capacity factor because of more continuous winds. At 100m height estimated global wind power is about 230 TW [3]. We can get high amount of wind energy (80 GW as in [4].) at

However, in addition to these conventional designs there have been some rather revolutionary wind turbine designs. One such design, currently being developed by Vortec Energy, is the diffuser augmented wind turbine. This Turbine is 21 stories tall and has the unique feature of an hourglass-shaped metal shroud, which surrounds a set of rotor blades ("It's an ill wind that blows no good", 21). This turbine has a power output six times that of a conventional turbine and the reason is that the shroud creates a region of low pressure that sucks air past the blades at twice the normal wind speed (Anderson, 1). Another innovative design, being developed by an Open University Team, is a vertical axis wind turbine. The advantage of this turbine over the conventional wind turbine which has a horizontal axis is that it can catch wind from any direction without being re-orientated ("It's an ill wind that blows no good", 21). Both of these designs are currently being tested in several countries but if they work they will make wind power even more efficient than current technologies have been able to achieve.

The gearbox and generator are the most important aspect of a wind turbine because without, energy would not be produced. With better technology increasing the production of energy. There have been different three stages to the development of wind turbine technology; stage 1, which consist of constant speed turbine with a squirrel-cage induction generator; stage 2, consist of a variable speed turbine with a squirrel-cage induction generator and fully-rated frequency converter; stage 3, which consist of a variable speed turbine with a wound-rotor induction generator and partially-rated frequency converted. Advancement in these stages has

I would like to express my deep appreciations to my mentor Ms.S.Yadav who have greatly helped me with this project.

Setting up windmills and other wind harnessing hardware is costly, the innovation behind it is additionally costly and concentrated expanding the underlying expense of setting out the plant (Krohn, Morthorst, and Awerbuch, 2009). Be that as it may, the examination demonstrates that the approach is unsurprising and sure in spite of the cost not at all like different sources particularly the non-sustainable

for providing us constantguidance during our project and providing us with an opportunity to apply the concepts learnt

Noisy, Monstrous, Nauseous, giant, unpleasant, bird scaring are some of the basic properties that blink in our mind when we think about wind turbines. If we specifically talk about horizontal axis wind turbine(HAWT) then most turbines are not efficient when it is installed closed to the ground where there is not much wind. Also, the tall towers and long blades are very expensive and difficult to transport and install. Another disadvantage of HAWT is that it is difficult to perform repairing operations to HAWT because the gear box , generator and the rotor are all placed at the top of the tower. So to overcome this problems there is another option of Vertical Axis Wind
