Modeling and Application of Universal Power Quality Controller System
並列摘要
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.
