4 FAQs about Wind power double-fed generator grid-connected

Is double fed induction generator suitable for grid-connected wind energy conversion system?

This paper presents the control strategies and performance analysis of doubly fed induction generator (DFIG) for grid-connected wind energy conversion system (WECS). The wind power produces environmentally sustainable electricity and helps to meet national energy demand as the amounts of non-renewable resources are declining.

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) is one of the main technologies employed in wind energy conversion systems (WECSs). The history of the development of this technology, its importance, and its singularities are pointed out. This chapter presents several representations used to model DFIG according to the main goal one has in sight.

How are rotor windings connected to the grid?

The rotor windings are connected to grid through two B-2-B converter bridges, while the stator windings are connected to the grid directly. The DFIG system has to experience high peak currents during grid failure in view of its fault ride-through capabilities, and an advanced protection scheme may be necessary.
