Variable Speed Of The Wind Turbine Generator With Dfig Connected To Electric Grid



Authors : Zellagui M. .

Abstract

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.
