Abstract

A power conversion device includes: a power converter which includes a plurality of converter cells; and a control device. The control device includes: a phase-balance control unit to generate arm-current command values, based on direct-current voltages of power storage elements of the plurality converter cells; a circulating-current control unit to generate a circulating-voltage command value for controlling a circulating current, based on the arm-current command values; a correction-voltage generation unit to correct a reference-voltage command value, using a correction value for suppressing an overcurrent due to a voltage imbalance of the power system, to generate a correction-voltage command value; a voltage-command calculation unit to generate arm-voltage command values, based on the circulating-voltage command value and the correction-voltage command value; and a gate-signal generation unit to generate control signals for the plurality of switching elements of the at least one arm, according to the arm-voltage command values.
