A wind mill is made by one or more aerogenerators that take advantage of the physical terrestrial wind features to produce electricity.
In turn an aerogenerator is made of a number of basic parts
- the rotor made of a circular crown (hub) to which are usually attached three glass or carbon blades;
- generator, attached to the rotor sometimes with the interposition of gear multiplier, which transforms mechanical energy into electricity with variable frequency;
- control and conversion system, placed inside the nacelle (or sometimes inside the tower or cabin), that regulates the functions of the entire system, assuring and guaranteeing the performances and security, among those the stabilisation of the frequency at 50 hertz of the network, the yaw (that is the rotor orientation with tail wind), the breaking;
- sustaining tower with its base.
