In this paper the power compensation for power system during faults in distribution line is described. The proposed system is designed by using the series and shunt APF based hysteresis control scheme to compensate harmonic distortion and control the system stability. Moreover, the system can be compensated the current as well as voltage simultaneously by using Unified Power Quality Controller (UPQC). Voltage Source Inverters (VSI) are connected in both the series and shunt. The main feeder is used to injecting power to these inverters using transformer and VSI compensate the imperfection line such as sag, interruption, swell, voltage unbalance. DC link voltage of the system is maintained at series and shunt operation. The proposed system is verified successfully and tested using MATLAB/Simulink.
