The average rating of newly installed windsturbines was 164 kW in 1990, in 2000 for the first time more than 1 MW, in 2009 for the first time about 2 MW. In 2011, it stood at 2.2 MW, with plants with an installed capacity from 2.1 to 2.9 MW dominated with a share of 54%. A further increase in average power rating is foreseeable, in part due to introduction of 3-MW onshore windsturbines and because of increasing construction of offshore winds farms, percentage of capital assets are built with a rated capacity from 3.6 to 6 MW (wind turbine maintenance Idaho).
The consideration of several windsturbines can be found in article winds farm, more applications and energy aspects in Articles Winds Energy, Renewable Energy and Energy Transition. The first documented system for power generation Established in 1887, the Scotsman James Blyth to charge batteries for lighting his holiday cottage.
Its simple, rugged design with a vertical axis of ten meters high and four arranged on a circle of eight meters in diameter Sailing a modest efficiency. Almost simultaneously, Charles F. Brush in Cleveland, Ohio oriented with a 20-meter-high plant at the time quite advanced windsmill technology. When it comes mills rather than on the torque on the speed; Brush used a two-stage translation with belt drives to drive a 12 kW generator.
To estimate the annual income the so-called average windspeed is given for the location windsturbine. It is an average winds velocities occurring over the year. The lower limit for the economic operation of a system is dependent on the feed-in tariff, at an average windspeed of 5-6 m / s at hub height. However, other factors need to be considered.
A winds assessment based on the frequency distribution windspeed for a location is the optimal choice of rated windspeed (usually 1.4 to 2 times the mean windspeed) or given plant data to estimate the energy produced per year, industry-standard specified as a full load hours (quotient of anticipated or actually achieved annual amount of power installed capacity).
About calculation programs on the internet can be the income of certain investments to be elected under conditions determined approximately. However, information on the actual income of a site can be only on winds measurements based winds reports. In this case, the degree of turbulence due to geological conditions, vegetation, higher buildings or adjacent windsturbines must be considered.
This energy is transported by the winds. In free flow far ahead of rotor of windsturbine, the power density of this transport. Due to this sharp increase in power density with the winds speed winds energy sites are particularly interesting. The tower height plays an important role, especially in inland areas where (buildings and vegetation) reduced the winds speed and increases the degree of turbulence.
A windsturbine Enercon E-126, with a capacity of 7.5 MW. Currently, the most powerful onshore windsturbine. Based on these small by today's standards plants found in 1990s and 2000s, the further development to modern large turbines instead. Since then, Denmark is the country with the largest winds power generation shares.
