Voltage sags can be defined as momentary reductions in supply voltage, lasting from a few milliseconds to a few cycles. Dynamic Voltage Restorer (DVR) and Distribution STATic COMpensator (D-STATCOM) can be used to correct the voltage sag at distribution level. In industrial area one 11KV feeder feeds an Induction motor load of variable power and then the normal domestic to industrial loads. Faults at Induction motor load effect the other feeder loads. This paper deals with the voltage dips and correction with DVR and D-STATCOM at the desired load point is studied by simulation.
