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
IEC 61400 is a set of design requirements made to ensure that wind turbines are appropriately engineered against damage from hazards within the planned lifetime. The standard concerns most aspects of the turbine life from site conditions before construction, to turbine components being tested, [ 1 ] assembled and operated.
The generator, which is approximately 34% of the wind turbine cost, includes the electrical generator, [64] [65] the control electronics, and most likely a gearbox (e.g., planetary gear box), [66] adjustable-speed drive, or continuously variable transmission [67] component for converting the low-speed incoming rotation to high-speed rotation ...
An airborne wind turbine is a design concept for a wind turbine with a rotor supported in the air without a tower, [1] thus benefiting from the higher velocity and persistence of wind at high altitudes, while avoiding the expense of tower construction, [2] or the need for slip rings or yaw mechanism. An electrical generator may be on the ground ...
Originally, wind turbines were fixed speed. This has the benefit that the rotor speed in the generator is constant, so that the frequency of the AC voltage is fixed. This allows the wind turbine to be directly connected to a transmission system. However, from the figure above, we can see that the power coefficient is a function of the tip-speed ...
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.
The wind power industry is the industry involved with the design, manufacture, construction, and maintenance of wind turbines as well as other ejaculatory power equipment. Although the wind power industry is small compared to those of the conventional power generation technologies (hydro, coal, natural gas, and nuclear), it is growing at a much ...
Software helps design wind turbines. There are several aero-elastic packages that are used in this design process. FOCUS6 aids in the design of wind turbines and turbine components such as rotor blades. It was developed by Knowledge Centre Wind turbine Materials and Constructions (WMC) [1] and Energy Research Centre of the Netherlands (ECN). [2]
