THREE-PHASE, PRECISE INDEPENDENT COMPENSATION SVG DEVICE AND CONTROL METHOD THEREOF

摘要

A three-phase, precise independent compensation SVG device and control method thereof. The device comprises three independent compensation units with two bridge arms. Each compensation unit with two bridge arms performs independently reactive compensation and harmonic compensation for one phase. The compensation unit of each phase can obtain precise reactive compensation and harmonic compensation for the phase. No coupling relation exists among the three phases, and thus precise compensation can also be carried out under the condition of unbalanced loads.
