Aiming at the influence of reactive load on the power quality of the grid, a three-phase four-wire static var generator (SVG) is researched. In order to deal with harmonic disturbance of the grid, the control strategy combining proportional resonance (PR) with repetitive control (RC) is proposed in the paper. In addition, the stability and harmonic suppression characteristics of the two different structures of the PR-repetitive control (PR-RC) strategies are analyzed and compared in detail. Finally, the theoretical analysis is verified by simulation.
