Power Quality Improvement using Unified Power Quality Conditioner with Distributed Generation [ ]


Recently power quality has become more important issue. Now a day’s power electronics based appliances are widely used in industries and in distribution system which creates more power quality problems. The power electronics based power conditioning devices can be an effective solution to improve power quality in power system. Unified Power Quality Conditioner (UPQC) is one of the custom power devices which are used to solve voltage and current related problems simultaneously. In this paper, combined operation of UPQC with Distributed Generation (DG) is discussed. This system integrated with wind energy is able to compensate voltage sag/swell, load current disturbances. Also proposed system is able to compensate voltage interruption and active power transfer to load and source in both interconnected and islanding mode and help to improve power quality. The operation of UPQC with DG has been evaluated through simulation studies using MATLAB/SIMULINK software.
