Vector Control of a Doubly Fed Induction Generator for Standalone Wind Energy Application

Indirect and direct vector control strategies can be applied to a stand alone doubly fed induction generator (DFIG) for wind energy applications. The control algorithm allows generating constant frequency and voltage with variable mechanical speed. The maximum power tracking can only be realised by controlling the load power. In this study the load was modelled as a controlled rectifier supplying an RL load. Simulation results for a 9 MW wind farm modelled as one aggregated DFIG machine are presented.
