  • Modeling and Characterization of a Wind Turbine

    A wind turbine is a device that transforms a part of the kinetic energy of the wind (fluid in motion) into available mechanical energy on a transmission shaft and then into electrical energy via a generator ()In fact, wind energy is a nondegraded renewable energy, is geographically diffuse, and is in correlation with the season (electric power is much more demanded in winter,Horns Rev offshore wind farm is located in North Sea 15 km western off Denmark coastline and consists of Vestas V80 2 MW wind turbines Wake modeling in Horns Rev wind farm is studied in many literatures , , The abundant LES and observation data for Horns Rev wind farm provide useful sources for validation purposeWake modeling of wind turbines using machine learningWind power of a wind turbine2 in the wind farm using the input wind data file1 Average Value of Physical Factors of Wind Power Model considered from the Designed Algorithm Estimated Average Power of Vestas V 90, 3 MW Wind Turbine Vertical shear at hub height 143 MW Turbulence adjusted speed at hub height 215 MW Estimated disc speed at hubMODELLING AND SIMULATION OF WIND SPEED AND
