Abstract
Static var generator(SVG) has found wide application in the distribution network thanks to its function in reactive power compensation and voltage stabilization.For solving the high-order harmonics generated by SVG in operation
LCL filter is generally used for filtering.The introduction of LCL filter affects the dynamic and static characteristics of SVG compensation.Therefore
a kind of a passive control method for SVG is proposed in this paper
which can improve the dynamic and static characteristics of SVG in operation.The effectiveness of the proposed strategy is verified by PSCAD-based simulation.
