Why is high efficiency important in wind power generation systems?

High efficiency: High efficiency is highly desirable in wind power generation systems so that the extracted energy from wind source can be converted as much as possible by reducing various electrical and mechanical losses.

What are the different types of wind turbine generation systems?

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).

What are the components of a wind 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 years 32, 33. The turbine converts wind energy into mechanical energy.

Can wind turbines improve efficiency and reduce costs?

In a bid to increase efficiency and reduce costs, wind turbine developers have produced a number of interesting, and perhaps radical, designs for new turbines, as well as further developed the capabilities of conventional models.

Can wind generation systems support grid frequency?

The ability of wind generation systems to support grid frequency is closely related to the synchronization mechanism. The conventional synchronization of wind generation systems with the power grid using PLLs typically involves power injection without offering frequency support.

What are electric machines & drives for wind turbines?

Electric machines and drives are the key enabling technology for wind turbines. The required basic characteristics of an electric machine–drive system for wind power generation are shown as follows.
