DFIG based standalone power system operating at low load conditions.
- Grzegorz Iwański
The comparison of inductive and capacitive filter for standalone variable speed operated doubly fed induction generator DFIG is presented in the paper. Simulation and experimental results of both methods of filtration are shown. The model equations with stator connected filtering capacitors are analyzed. Sensorless control of the stator voltage vector in the polar frame is described. PLL based frequency control of generated stator voltage is presented. Modification of the control system allow for faster synchronization of the actual and reference voltage vector, what provide shorter start-up procedure of the system and better stabilization especially at low load conditions. Simulation and experimental results of improved frequency control of the standalone doubly fed induction generator are presented.
