The majority of wind turbines have a horizontal axis: a propeller-style design with blades that rotate around a horizontal axis. Horizontal axis turbines are either upwind (the wind hits the blades before the tower) or downwind (the wind hits the tower before the blades). Upwind turbines also include a yaw drive and motor -- components …
Conceptual design of horizontal axis wind turbines
Within the general category of horizontal axis wind turbines for grid applications, there exists a great variety of possible machine configurations, power control strategies, and braking systems. The machine rating determines the wind speed at which rated power is reached.
Types of Wind Turbines: HAWT, VAWT and More Explained
The most common type of wind turbine is the ''Horizontal Axis Wind Turbine'' (HAWT). It is referred to as a horizontal axis as the rotating axis lies horizontally (see diagram, below). A HAWT needs to point directly into the wind to operate at maximum efficiency, and the whole head is designed to turn to face the wind.
At the moment, the HAWT, which stands for horizontal axis wind turbine, is the kind of wind turbine that is used the most often. These turbines make use of airfoils, which are essentially aerodynamic blades, and link them to a rotor by putting themselves either in the upwind or downwind direction.
Aerodynamics and Design of Horizontal-Axis Wind Turbines
Modern wind turbine can further vary the angular velocity within a certain range. And assuming that for a given wind turbine the power depends on the air density, the viscosity, the wind speed, the rotor radius, the angular velocity, and the pitch angle as (9.32) P = f (ρ, μ, V o, R, ω, θ p) one can derive that (9.33) C p = f (ρ V o R μ ...
