Abstract：In this paper, a three-phase three-wire unified power quality controller based on combining harmonic detection of the generalized instantaneous reactive power with a timing control of the instantaneous value of comparative law and SVPWM control method, by using the harmonic source of a controlled bridge rectifier with resistive inductive load is presented . Through simulation, the paper verifies the following facts: While the current and voltage of power network distorts, this program can have a good tracking harmonic, and has a good dynamic response speed and higher compensation effect.
