<P>PROBLEM TO BE SOLVED: To provide a fully centralized compensation reactor system in a substation which when a ground fault accident occurs on a distribution line, suppresses a current resulting from the earth capacitance of the distribution line, and allows insertion of a proper amount of a reactor in each distribution line. Ž<P>SOLUTION: The fully centralized distribution line individual compensation reactor system in a substation compensates the earth capacitance of each distribution line via a zero-phase current transformer attached to each distribution line. The distribution line individual compensation reactor system includes a variable compensation reactor means 1 connected to a busbar 6 of distribution lines, a plurality of through ground lines which are connected to one end of the variable compensation reactor means 1 and are grounded through the zero-phase current transformer of each distribution line, and a ground line switching means which is connected in series to change the number of through ground lines for each distribution line for distributing compensation reactor amount in proportion to the number of through ground lines.
