Abstract
A direct-current-controlled Static Var Generator (SVG) is proposed to solve the voltage unbalance issue at the Point of Common Coupling (PCC). The SVG is operated as a current source controlled by the negative sequence voltage at the PCC. The relationship between all the parameters and the compensating characteristics is analyzed in detail. And an optimum control parameter is decided. The negative sequence voltage decomposition method is also introduced. Simulation and experiment results verify the satisfactory performance of the SVG in compensating voltage unbalance with the proposed control strategy.
