As much as nonlinear loads and power electronics devices are more applied in power distribution
systems, the importance of power quality increases. This study proposes a Universal Power Quality Conditioner
(UPQC) with double-converter structure. The operation principle, the algorithm of compensation reference
generation, and the control method are introduced. Computer simulation and many prototype experiments are
carried out to verify the operation principle and investigate the compensation characteristics of UPQC for
different power quality problems. It is verified that the UPQC can effectively compensate multiple different
power quality interferences originated either from the load side or from the line side. The capacity of series and
shunt inverters is calculated through loading calculations of these inverters applying phasor diagram to increase
the design accuracy. The results of simulation in MATLAB/SIMULINK software show that the system operates
correctly.
Key words: Active power filter, inverter loading, power quality, Universal Power Quality Condetonor (UPQC), , ,
