What is wind power generation?

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.

What are the components of wind power generation system?

In terms of configuration, wind power generation system normally consists of wind turbine, generator, and grid interface converters where the generator is one of the core components. There are the following wind power generation technologies such as synchronous generator, induction generator, and doubly fed induction generator.

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).

How much energy does wind power generate a year?

Wind power generation technology is now relatively mature, with annual generation amounting to 640 TWh, accounting for less than 3% of the world’s total energy consumption.

How efficient is a wind generator?

A 100% efficient wind generator can transform maximum up to 60% of the available energy in wind into mechanical energy. In addition to this, losses occurring in the generator or pump decrease the overall efficiency of power generation to 35%. III. PRINCIPLE OF ENERGY CONVERSION:

What are the different types of wind power generators?

Among the most common varieties of wind power generators now available is the doubly-fed induction generator (DFIG). It typically operates in MPPT condition (maximum power point tracking) , where the speed of the rotor is uncoupled from the power system.
