Book excerpt: Master's Thesis from the year 2018 in the subject Engineering - Power Engineering, grade: 9, language: English, abstract: The rising demand of electricity and the environmental concern in the recent past necessities the need of renewable energy sources. The Renewable energy sources have gained major importance due to the depletion of the conventional fuels in the future. Among the available renewable sources the Wind energy has gained a significant importance due to its high efficiency and pollution free nature. Large Wind Farms have been set up to meet the energy demand globally. The capacity of the Wind Turbine Generator is being increased gradually from a few KW capacities in the beginning rising up to almost 5 MW in the present. More research has to be carried in this field to make it a dominant source for the rising energy demand. Wind energy potential has to be harnessed on a large scale in places which have high wind density. Before the actual commissioning of the Wind Farm on site, a wide range of analysis has to be carried in terms of simulation. This is done to understand the behavior of the system under various conditions and preventive actions if any are to be taken. The pre analysis gives us an idea of the selection of devices for higher efficiency and system reliability. This project is a research work carried in ETAP (Electrical Transient Analyzer Program), which is a Power System Simulation tool. The analysis carried out to demonstrate the capabilities of the SCIG (Squirrel Cage Induction Generator) based Wind Farm include Load Flow analysis, to find out the Power transferred to the Grid in normal condition at rated Wind Speed.

This book was released on 2008-08-19 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among renewable sources wind power systems have developed to prominent s- pliers of electrical energy. Since the 1980s they have seen an exponential increase, both in unit power ratings and overall capacity. While most of the systems are found on dry land, preferably in coastal regions, off-shore wind parks are expected to add signi?cantly to wind energy conversion in the future. The theory of modern wind turbines has not been established before the 20th century. Currently wind turbines with three blades and horizontal shaft prevail. The drivenelectricgeneratorsareoftheasynchronousorsynchronoustype,withorwi- out interposed gearbox. Modern systems are designed for variable speed operation which make power electronic devices play an important part in wind energy conv- sion. Manufacturing has reached the state of a high-tech industry. Countries prominent for the amount of installed wind turbine systems feeding into the grid are in Europe Denmark, Germany and Spain. Outside Europe it is the United States of America and India who stand out with large rates of increase. The market and the degree of contribution to the energy consumption in a country has been strongly in?uenced by National support schemes, such as guaranteed feed-in tariffs or tax credits. Due to the personal background of the author, the view is mainly directed on Europe, and many examples are taken from the German scene. However, the sit- tion in other continents, especially North America and Asia is also considered.
