Composition of Berne s wind power generation system

In wind generation systems, the wind turbine, the electrical generator and the grid-interfaced converters are three key components that have been developed in the past 30 years32,33. The turbine converts wind energy into mechanical energy.

Fig. 5 is the typical framework of a wind power generation system. For a wind power generation system, the wind turbine is a critical part. Modern wind turbines (Fig. 6) can be divided into horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT).

It also must have one or more of the following additional components: Anemometers, which measure the wind speed and transmit the data to the controller. Numerous sensors to monitor and regulate various mechanical and electrical parameters. A 1-MW turbine may have several hundred sensors.

Wind power generation is power generation that converts wind energy into electric energy. The wind generating set absorbs wind energy with a specially designed blade and converts wind energy to mechanical energy, which further drives the generator rotating and realizes conversion of wind energy to electric energy.

Two typical configurations of power electronic converter-based wind turbine generation systems have been widely adopted in modern wind power applications: type 3 wind generation systems with doubly fed induction generators (DFIGs) (Fig. 2a); and type 4 wind generation systems with permanent magnet synchronous generators (PMSGs) (Fig. 2b).

In a modern wind farm, each turbine must have its own control system to provide operational and safety functions from a remote location. It also must have one or more of the following additional components: Anemometers, which measure the wind speed and transmit the data to the controller.
