Wind turbine design is the process of defining the form and configuration of a wind turbine to extract energy from the wind. [1] An installation consists of the systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power , and other systems to start, stop, and control the turbine.

The active yaw systems are equipped with some sort of torque producing device able to rotate the nacelle of the wind turbine against the stationary tower based on automatic signals from wind direction sensors or manual actuation (control system override). The active yaw systems are considered to be the state of the art for all the modern medium ...

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.
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.
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]
Schematic representation of the main wind turbine components. The yaw system is located between the wind turbine nacelle and tower.. The yaw bearing is the most crucial and cost intensive component of a yaw system found on modern horizontal axis wind turbines.
