Development of a Fuzzy Controller with UPFC’s For Damping of Oscillation in Multi-machine Integrated Power System

Vibha N. Parmar; Ashok L. Vaghamshi

In This paper damping of oscillations in FACTS based integrated multi-machine power system. When 3 phase to ground symmetrical fault is made to occur near each generator. (one fault at a time). The multi-machine system consists of 3 generators, 3 transformers, 9 buses, 4 loads {&} 2UPFCs. Simulations are performed with {&} without the controller. UPFC based POD controllers can be used to suppress the oscillations upon the occurrence of a fault at the generator side . This paper depicts about this hybrid combination of a fuzzy with a UPFC {&} POD control strategy to damp the electro-mechanical oscillations. Digital simulations of a multi-machine power system subjected to a wide variety of disturbances are validating the efficiency of the power system
