Abstract
A power conversion device in one embodiment includes power conversion circuitry having a plurality of converter cells connected in series to each other. Each converter cell includes an energy storage device and is configured to be capable of discharging stored energy. A control device is configured to generate a control command for controlling operation of each converter cell. A protection device is configured to generate a protection command for instructing whether to cause each converter cell to operate based on the control command or to stop operation of each converter cell regardless of the control command. A repeating device is configured to generate a control-and-protection command that is a combination of control information based on the control command and protection information based on the protection command, and output the generated control-and-protection command to each converter cell.
