6 FAQs about [Doubly-fed wind turbine generator set structure]

What is a doubly fed generator for wind turbine?

Doubly fed generator for wind turbine. Doubly fed electrical generators are similar to AC electrical generators, but have additional features which allow them to run at speeds slightly above or below their natural synchronous speed. This is useful for large variable speed wind turbines, because wind speed can change suddenly.

What is doubly fed induction generator?

The doubly fed induction generator (DFIG) is a portion of wound rotor and an adjustable speed IG widely used in wind power industry. DFIG provides high energy yields, reduction of mechanical loads, simpler pitch control, less fluctuations in output power, an extensive controllability of both active and reactive powers .

What is doubly fed induction generator (DFIG)?

Doubly fed induction generator (DFIG), a generating principle widely used in wind turbines. It is based on an induction generator with a multiphase wound rotor and a multiphase slip ring assembly with brushes for access to the rotor windings.

How does a double fed wind turbine work?

The stator of the doubly-fed wind turbine is directly connected to the grid and can only output power. In contrast, the rotor is connected to the grid through an AC/DC/AC power converter, with power flow determined by the generator's operating mode.

What is a DFIG wind turbine rotor?

The DFIG is currently the system of choice for multi-MW wind turbines. The aerodynamic system must be capable of operating over a wide wind speed range in order to achieve optimum aerodynamic efficiency by tracking the optimum tip-speed ratio. Therefore, the generator’s rotor must be able to operate at a variable rotational speed.

What is a double-fed induction generator?

Paul Breeze, in Wind Power Generation, 2016 A more modern and more flexible version of the induction generator that is used in large wind turbines is a variant called the doubly-fed induction generator. In a conventional induction generator the generator stator is connected to directly to the grid and the rotor is a closed loop coil.
