Abstract : The performance analysis of three phase three wire voltage source inverter based unified power quality conditioner
(UPQC) with a control configuration is implemented in this paper. UPQC is utilized for power quality improvement at
distribution level. The operation of UPQC combines the operations of series component Dynamic Voltage Restorer (DVR)
and shunt component Distribution Static Compensator (DSTATCOM) together. The series component of the UPQC inserts
voltage so as to maintain the voltage at the point of common coupling balanced and free of distortion. Simultaneously, the
shunt component of the UPQC injects current into the system such that the currents entering the bus to which the UPQC is
connected are balanced sinusoids. Both these objectives must be met irrespective of unbalance or distortion in either source or
load sides. When UPQC is used in a power distribution system, the series and shunt active filters of the UPQC are made to
operate in an effective and efficient unified manner. The control strategy should be able to reduce the negative effects of the
variations in distorted supply voltage and the nonlinear load current. The control signals, generated by the various functional
modules of the control design circuit Discrete Proportional IntegralController. Phase Locked Loop and Discrete Pulse Width
Modulation Generator, will be the switching schemes for the series and shunt active filters of the UPQC to provide
simultaneous shunt and series compensation in a power distribution system. The validation of performance analysis of three
phase three wire voltage source inverter based unified power quality conditioner is verified through simulation inMatlab.
Keywords- Compensation, Distribution Static Compensator, Dynamic Voltage Restorer and Unified Power quality
