Humans have invented thousands of machines and gadgets that use energy to make everyday works easier. For example, to warm our house, to get ourselves from one place to another. Some of these machines use electricity, while others, such as cars, use the energy stored in gasoline. Much of the energy supply comes from coal, oil, natural gas or radioactive element. In fact, all these deposits of natural resources took millions of years to form. They are considered non-renewable, which means that once removed from the ground, they are not replaced immediately in human time.
This current topic is frequently discussed worldwide to find a solution. At the present time, it will be necessary to seek renewable or practically inexhaustible energy for human development to continue. Renewable energy is defined as the energy generated by natural resources such as wind, sunlight, water that are quickly replaced and usually in the endless source. Exploring renewable energy is the only approach to reduce our dependence on fossil fuels. Among renewable energy resources, wind energy is the only resource that will be discussed in this document. Wind energy was first harvested centuries ago, when early windmills were used for power mills, pumps and forges. More recently, wind is harnessed by the use of a special manifold, called wind turbine to produce a clean and safe source of electricity.
This project focuses on the use of wind energy as a renewable source. Wind energy, as an alternative to fossil fuels, is abundant, renewable, widely distributed, clean, does not produce gas emissions during operation and uses little soil. Any effect on the environment is often less problematic than that of other energy sources. As of 2011, Denmark is generating more than a quarter of its electricity, and 83 countries around the world are using wind power on a commercial basis. In 2010, wind power production exceeded 2.5% of total global electricity consumption and grew rapidly by more than 25% per year. The monetary cost per unit of energy produced is similar to the cost of new coal and natural gas facilities. The development of wind energy in India began in the 1990s, and has increased significantly in recent years. India has the fifth installed wind power in the world. In 2009-10 India's growth rate was highest among the other four countries. In India, wind capacity is approximately 6% of total installed power and continues to grow with the facilitation of new wind projects.
Various designs have been proposed to create a high efficiency wind turbine that is capable of generating maximum electrical energy. They can either design the shapes of the turbine blades, the axis of rotation, and other useful modifications. Recently, an advanced technique, magnetic levitation (Maglev) is incorporated into the turbine system to meet the needs of those energy industries. The objective of this important qualification project is to design and implement a magnetically levitated vertical axis wind turbine system. Our choice for this model is to show its efficiency in different wind conditions compared to the traditional horizontal axis wind turbine and contribute to its steadily increasing popularity in order to mass use in the near future as a reliable source of generation Energy.
Unlike the traditional horizontal axis wind turbine, this design is levitated via maglev (vertical levitation) on a rotor shaft. The Maglev phenomenon operates on the repulsion characteristics of the permanent magnets. This technology has been used mainly in the rail industry in the Far East to provide very fast and reliable transport on maglev trains and with ongoing research its popularity is increasingly reaching new heights. Using a pair of permanent magnets like neodymium magnets and substantial magnetic levitation support can be easily experienced. By placing two magnets one on top of the other with the same polarities they face, the magnetic repulsion will be strong enough to hold both magnets at a distance from each other. The force created as a result of this repulsion can be used for suspension purposes and is strong enough to balance the weight of an object depending on the threshold of the magnets.
