Research on three-phase unbalance decrease of distribution network based on SVG

Abstract

Aiming at various unbalanced load added to the Electric System, Which lead to the three-phase current imbalance problem, Based on the existing solutions, the Static Var Generator (SVG) is proposed to balanced three-phase current, Whose control structure and working principle are introduced, and the simulation test platform is built. the results of which show that the device has good dynamic balance performance, reducing the reactive power and improving power factor at the same time, which greatly improved the power quality.
