Wind Turbine Location

A wind installation on a large scale, called wind farm or wind farm consists of a collection of these turbines. There are two main factors to consider when making a site for wind turbines. These are the location where the turbines are located and the other is the height the towers will have. Below we explain both factors. Exact estimates of the speed of the wind are critical when evaluating the potential of wind energy in any location. Wind resources are characterized by a scale of wind classes according to their speed, that extends class 1 (lowest) to class 7 (highest). The unevenness of the surface through which the wind is blowing before reaching a turbine determines the amount of turbulence that turbine will experience. The turbulent winds put greater stress on the rotor and soar, consequently reducing the life expectancy of the turbine. Thus, the majority of wind farms are located in rural locations, far from buildings, trees and other obstacles. While the technical characteristics of the wind in a specific location are very important, many other factors also contribute to the decision of the site. A location away from the electric distribution network can become unprofitable, because they will require new transmission lines to connect wind farm with the network. The existing transmission infrastructure may require an extension to be able to handle the additional power source. Soil and terrain conditions should be suitable for the construction of the foundations of the towers. Finally, the choice of a location may be limited by regulations on the use of land and the ability to obtain the required permissions of local, regional and national authorities. The Tower's height affects the amount of power that can be obtained with a given turbine wind, as well as tensions over the rotor. At an altitude of one kilometer on the surface, wind speeds are not influenced by the ground below. The wind moves more slowly as more baja is tall, with the maximum reduction of wind speed located very close to the surface. This phenomenon, known as shearing of the wind, is a factor at the time of the decision on the height of the Tower, since with a greater height rotors are exposed to faster winds. In addition, differences between the top and bottom of the rotor of the wind speed decreases to higher altitudes, causing less wear on the turbine.
