Was doing a bit of research on wind turbine components.
My interest was in both the main components and the sub-components. The primary components of a wind turbine (and the associated wind power plant) are as follows:
Primary Wind Turbine Components
- Blade
- Shaft
- Gearbox
- Generator
- Nacelle
- Tower
Other Wind Turbine Components of Importance
- Rotor
- Yaw mechanism
- Anemometer
- Brakes
The rest of the components that complete the wind power plant include
Our specialty focus areas include
- Power converter
- Transformer
While reading up on the above, some of the web resources I came across were quite good; thought it could be useful to many other who could be interested in this topic as well

The two pictures above say it all; both in terms of the key components, and which are the most costly components.
