ABSTRACT:

ABSTRACT

In this paper Power Quality (PQ) improvement for a distribution system is presented using Dynamic Voltage Restorer (DVR) and Unified Power Quality Conditioner (UPQC) controllers. DVR and UPQC are widely adopted custom devices that are reported for mitigation of voltage sag. Voltage sag is a result of the faults in the power system. The designed UPQC and DVR systems help in obtaining regulated and balanced output voltages with reduced harmonics across the load terminals. Also, they suppress the source harmonics generated by the loads. The Matlab simulation model is presented for both the types of controllers using synchronous reference frame. Their performances have been analyzed under 3-phase fault condition and the results are compared to assess the improvement achieved in power quality by DVR and UPQC devices.
