get advantages of wind to produce electricity as the wind has a Kinetic energy. Kinetic energy is the main factor in converting the wind energy into electricity. The wind energy is produced by using a specific type of turbines called wind turbine, where this turbine absorbs the kinetic energy and produces the electricity power 2 Ð.

3. Energy transformations in a wind turbine A wind turbine uses energy transfer and energy transformations to generate electricity.

of integrity. The wind load beyond which loss of integrity can be expected is referred to as ultimate wind load. The nominal ultimate strength provided for by the designer is based on an assumed ultimate wind load equal to the design wind load times a wind load fac:tor.

Aerodynamics of Wind Turbines Emrah Kulunk New Mexico Institute of Mining and Technology USA 1. Introduction A wind turbine is a device that extracts kine tic energy from the wind and converts it into mechanical energy. Therefore wind turbine power production depends on the interaction between the rotor and the wind.

Wind turbines use the kinetic energy of the wind and convert it to mechanical energy. This is then used to produce electricity, grinding of grain or pumping of water (windmills, wind pumps). There are two types of wind turbines, horizontal and vertical. Vertical axis wind turbines (VAWT) have the rotor shaft vertically.

For application in wind energy resource assessment, sodar is primarily used to (1) measure the characteristics of the wind shear profile at heights above ground where wind turbine rotors operate, and/or (2) compare the wind conditions at selected sites relative to one or more reference wind measurement locations (typically meteorological masts).
