Variable speed of the wind turbine generator with DFIG connected to electric grid

Zellagui M.

The variable speed wind turbine generator with doubly-fed induction
generator (DFIG) is today widely used concept. This paper presents a control system of
the doubly-fed induction generator wind turbine with focus on the control strategies and
on active power reference value choice. The present control method is designed for supersynchronous,
subsynchronous and synchronous working modes. In order to investigate
the dynamic responses during step load of doubly fed induction generator connected to
the electric grid (EG), a model has been developed. This model includes the mechanical
drive train, the induction generator as well as the control parts.
