Abstract :
The aim of this paper is to explore the various dynamic controllers to enhance the fault ride-through (FRT) of doubly-fed induction generators (DFIGs). A wind farm of total capacity 9 MW is considered for the study. The flexible AC transmission system (FACTS) controllers like Static Synchronous Compensators (STATCOM) and Unified Power Flow Controllers (UPFC) are modelled and analysed to study their effect on the voltage at the point of common coupling (PCC) and FRT capability. This is then compared with the FRT capability of existing crow bar controller added to the converters of DFIG. The simulation is carried out using MATLAB/Simulink. A new Simulink model is developed for DFIG, to make it versatile for any FRT control strategy. The results presented show the effectiveness of the model.
