6 FAQs about [Wind power double-fed asynchronous generator]

What is advanced control of doubly fed induction generator for wind power systems?

Advanced Control of Doubly Fed Induction Generator for Wind Power Systems is an ideal book for graduate students studying renewable energy and power electronics as well as for research and development engineers working with wind power converters.

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 .

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 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.

What is a DFIG wind turbine?

The construction of a DFIG is similar to a wound rotor induc-tion machine (IM) and comprises a three-phase stator winding and a three-phase rotor winding. The latter is fed via slip rings. The voltage and torque equations of the DFIG in a stationary ref-erence frame are: Doubly fed induction generator wind turbine system. speed ratio n/n0 (right).
