A Power System is actually a vast system thatrequires an outstanding plan for maintaining the continualflow of electricity. When a fault occurs at the powersystem, number of difficulties arises because of transientsin system. so to attenuate these transients, powerelectronics based devices like FACTS are utilized. Aunified power flow controller (UPFC) is one amongdifferent power electronics controller which can dispenseVAR compensation, line impedance control and phaseshifting. The thought is to see potential of UPFC to requirecare of active and reactive power movement within thecompensated line (including UPFC) and to shrink the falloff of the bus voltage in case of grounding fault within thecable. power system block consisting of simulink is usedfor numerical analysis. Simulation outcomes fromMATLAB reflects major improvement in the overallsystem’s behaviour with UPFC in sustain the voltage andpower flow even under severe line faults by properinjection of series voltage into the cable at the point ofconnection. outcomes shows how the UPFC contributeseffectively to a faster regaining of the power system to the pre-fault conditions.
