This paper presents the design and development of a fuzzy controller using UPFCs to damp out the oscillations in FACTS-based integrated multi-machine power system when faults takes place at different buses. The combination of a fuzzy coordination scheme with a POD-based UPFC is used to suppress the oscillations upon the occurrence of a fault at the generator side. Three Simulink models are developed with and without the controller by considering the occurrence of one fault at a time near each generator. The three-phase to ground symmetrical fault is made to occur near first generator for 200 ms in the model 1, next at second generator in model 2 and finally at third generator in model 3. Simulations are performed with and without the controller. The three models are compared for the effectiveness of the fault occurrence near each of the generators. Simulation results show the effectiveness of the developed method.
