Abstract :
The paper analyzed the defects and causes of shunt APF and serial APF when they are used to suppress the distortion in load current or in source voltage separately. It also introduced the operation principle of unified power quality compensator (UPQC), which is able to compensate for both the source voltage and load current at the same time. The paper proposed the reference criteria comparison detection method for voltage distortion, dq0 detection method for current distortion and PI control strategy for stabilizing the voltage of DC capacitors. Simulation result verified the correctness of analysis and the effectiveness of UPQC design.
