A review of numerical modelling and optimisation of the floating

Other examples of structure control based on mass-spring-damper systems in different parts of the floating wind turbine structure can be found in Si et al. ; Dinh et al. ; Li and

How Are Wind Turbines Made?

Made of fiberglass, the nacelle houses the gearbox, generator, and electronic systems for each wind turbine. In both onshore and offshore wind turbines, a crane lifts the nacelle onto the top of the tower. Inside the nacelle

How a Wind Turbine Works

The tower and the nacelle of a wind turbine are usually made out of cylindrical steel and can either be supported by guy wires and guy tensions or stand alone using a lattice standing base. Again, this diagram shows an example of an up

Anatomy of a wind turbine: Analysing the key

The nacelle houses a wind turbine''s generator, and is mostly commonly manufactured as either gear-driven or direct drive. A wind turbine''s nacelle houses a multitude of sub-components (Credit: Fabricators &

Wind turbine

Modern wind turbines come a variety of sizes but all types generally consist of several main components: Rotor Blades - The rotor blades of a wind turbine operate under the same principle as aircraft wings. One side of the blade is

The Parts of a Wind Turbine: Major Components Explained

According to the structure of a nacelle of a horizontal axis wind turbine, the rotation of the blades is driven by wind energy and controlled by the nacelle, which may face the blades to the wind (yaw control) and change the

6 FAQs about [Wind turbine nacelle structure]

How much does a wind turbine nacelle weigh?

The nacelle is the ‘head’ of the wind turbine, and it is mounted on top of the support tower. The rotor blade assembly is attached to the front of the nacelle. The nacelle of a standard 2MW onshore wind turbine assembly weighs approximately 72 tons. Housed inside the nacelle are five major components (see diagram): a. Gearbox assembly b.

What is a nacelle in a wind turbine?

The nacelle sits atop the tower and contains the gearbox, low- and high-speed shafts, generator, and brake. Some nacelles are larger than a house and for a 1.5 MW geared turbine, can weigh more than 4.5 tons. The yaw drive rotates the nacelle on upwind turbines to keep them facing the wind when wind direction changes.

How many rotor hubs are in a wind turbine nacelle?

200-ton wind turbine rotor hubs that will be installed at the forward end of the nacelles. A nacelle / nəˈsɛl / is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly.

What are nacelle components?

Key nacelle components include the main bearing, gearbox (where used), generator, yaw bearing and yaw system. The main bearing supports the rotor and transfers the rotor loading to the nacelle bedplate. Several bearing arrangements exist for offshore wind turbines including a single bearing supporting the generator and rotor.

What is the difference between a nacelle and a floating wind turbine?

The nacelle incorporates high levels of remote monitoring, health checking and control. There are no major differences in the nacelles designed for floating or fixed offshore wind farms. Adjustments are needed to the control system to make the turbine suitable for application in floating.

What is nacelle manufacturing?

Nacelle manufacturing is a key activity encompassed by the Turbine Manufacturing step of our On-Shore Wind value chain. The nacelle houses the drivetrain, which is typically composed of the rotor shaft, gearbox and generator, and contains a yaw drive system and a control system.
