Advantage And Disadvantage Of Wind Energy
In recent days, because of energy shortage and environmental contamination, the renewable energy is increasingly valued and it has been employed worldwide. A typical renewable energy system has renewable energy sources, such as wind power generation, fuel cells, and solar systems, convert sources energy into electrical energy, which generate low output voltage. Because of low output voltage, this system required high DC/DC convertor which convert low voltage into high voltage, that commonly used in many renewable energy system. Thus high step up conversion is most important in renewable energy sources system because of its high efficiency with sufficiently high step up conversion.
In all over the world, wind energy becomes a research focus and it has more priority among various types of renewable energy. Wind energy is one of the fastest growing energy because of free availability, friendly environment and the development of turbine techniques, is becoming the key part among the serious energy sources [1], [2]. In wind energy conversion system (WECS), the doubly fed induction generator (DFIG) – based WECS and the direct drive permanent magnet synchronous generator (PMSG) – based WECS are regularly used turbine structure for variable speed wind turbine.
This block diagram shown in Fig 1.1 represents the proposed method of ILBC. The three phase input voltage which is produces by wind generator is fed to three phase diode rectifier and in turn it converts into a dc source. The

Pros And Cons Of Windrider
399 Words | 2 PagesIn Dragonwings, Windrider is described as a practical person and idealistic person. He is idealistic because he dreamed of becoming a dragon again and he is practical by taking steps to become a dragon. Being practical means taking step by step or little by little to achieve a goal of some kind and being idealistic means dreaming big. It is more valuable to be practical rather than idealistic because by being practical, people can achieve their goals rather than simply dreaming about it. Being practical is better than being idealistic because little by little someone can finish a goal.

The Pros And Cons Of Wind Power
1318 Words | 6 PagesIn today’s world, energy demands are constantly expanding. The use of fossil fuels as the main energy source in the United States has lead to environmental pollution and there are also concerns for the supply of fossil fuels. In response to the growing global concern for alternative sources of energy that are environmentally friendly, there has been significant development over the years for wind energy production and other energy sources. However, as development of wind energy production has increased, there have been claims made against the strategies used to produce power from wind that dub them as being unclean, and in fact not environmentally friendly. As such, the controversy lies in whether large-scale wind power is in fact environmentally
Essay On Wind Energy
1104 Words | 5 PagesFor many years now, it has been debated which of the new and upcoming renewable and sustainable energy sources if the best to use. Energy create from wind, is a very favourable contented in this debate as it is a very good alternative energy source. Wind energy is used all around the world. Humanity has been using wind energy for over 100 years. For example, we used to (some still do) use the wind energy to grind grain in old fashioned wind mills..
Pros And Cons Of Alternative Energy Sources

There is one very important nuance in the operation of windmill - their stable location towards the wind. The wind is constantly changing its direction and strength, resulting in leaps and bounds, and that is the time when the generator is running. To eliminate unevenness applied voltage stabiliser that keeps the output voltage within the normal range, which do not depend on the whims of the wind. Another innovation which we are going to face soon is that the windmill are going to be able to move with the direction of the
