Abstract
A control device of a self-excited reactive power compensation apparatus controls a reactive current output from a self-excited converter to a power system. The control device includes a first reference generating unit, a second reference generating unit, and a selecting unit. The first reference generating unit generates a first voltage reference of an output voltage output from the self-excited converter, such that the reactive current detected by a reactive current detecting unit follows a current reference. The second reference generating unit generates a second voltage reference of the output voltage output from the self-excited converter, such that a value of the reactive current becomes a predetermined value. The selecting unit selects a maximum value from the first and second voltage references.
