Wind Power :: essays papers

Wind PowerThe bring up turbine, also called a windmill, is a misbegots of harnessing thekinetic energy of the wind and converting it into electrical energy. Thisis accomplished by turning blades called aerofoils, which drive a shaft,which drive a motor (turbine) and ar e connected to a generator. It isestimated that the total power capacity of winds meet the earth is1 x 1011 Gigawatts (Cheremisinoff 6). The total energy of the windsfluctuates from year to year. wind generator expert Richard Hills said that thewind really is a fickle extraction of power, with wind speeds to low orinconsistent for the windmill to be of possible use. However, thathasnt stopped windmill engineers from trying. Today, there argon manykinds of windmills, some of which parcel out differen t functions. They atomic number 18 acomplex alternative energy source. What to opine when building a windmill In choosing where to build awindmill, there are many important factors to consider. First is thel ocation 1) Available wind energy is usually higher near the seacoast orcoasts of rattling giving lakes and offshore islands. 2) Available wind energyis gene torment high in the central plains region of the U.S. because of thewide expanses of level (low bob up roughness) terrain. 3) Available windenergy is generally low throughout the south U.S. except forcertain hills in the Appalachian and Blue Rid ge Mountains, the NorthCarolina coast, and the Southern tip of Florida. This is because of theinfluence of the Bermuda high pressure system, which is a factorespecially during the summer. Also important to consider is the windwhere you are going to build 1) the remember wind speed (calculated mycubing the averages and taking the mean of the cubes) and its seasonalvariations. 2) The probability distribution of wind speed and of extremewi nds. The mean wind speed moldiness be high enough, and the distribution mustbe so that all the data points are very similar. 3) The superl ative variationof wind speed and wind direction. Wind cannot be similarly high or too low inrelation to the backcloth or it is too difficult to harness. 4) The gustiness of the wind field in both speed and direction. Gusty winds greatly affect the power output of thewindmills and are usually harmful. 5) The wind direction distribution andprobability of sudden large slopes in di rection. The wind must beunlikely to suddenly shift direction.
