The NASA/GE MOD-1 wind turbine in Boone, North Carolina was the world's first turbine to produce 2 MW. NASA contracted with General Electric in 1978 to scale up from the MOD-0A with a 10-fold increase in power. The Mod-1 was the first wind turbine in the world to produce 2 megawatts and also General Electric's first wind turbine.
Wind-turbine blades in laydown yard awaiting installation. The primary application of wind turbines is to generate energy using the wind. Hence, the aerodynamics is a very important aspect of wind turbines. Like most machines, wind turbines come in many different types, all of them based on different energy extraction concepts.
A wind turbine is a device that converts the kinetic energy of wind into electrical energy. As of 2020, hundreds of thousands of large turbines, in installations known as wind farms, were generating over 650 gigawatts of power, with 60 GW added each year. [1]
A vehicle with a bladed rotor mechanically connected to the wheels can be designed to go at a speed faster than that of the wind, both directly into the wind and directly downwind. Upwind, the rotor works as a wind turbine driving the wheels. Downwind, it works as a propeller, driven by the wheels. In both cases, power comes from the difference ...
An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
Counter-rotating wind turbines Light pole wind turbine. Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2024, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.
The RETScreen software wind power model is designed to evaluate energy production and savings, costs, emission reductions, financial viability and risk for central-grid, isolated-grid and off-grid wind energy projects, for multi-turbine and single-turbine hybrid systems.
In 2006, Wind Harvest International began design work on a series of Windstar turbine models to take advantage of the properties demonstrated in the 530G LAVTS prototype: Model 636, 1500 and 3000 turbines. The Model 636 is a direct evolution of the 530G, with an increase in blade length, in order to increase swept area, and including a modified ...
