POWER CONVERSION DEVICE

A power conversion device includes a power conversion circuit and a control device. The control device includes a virtual power generation device model unit and a control signal generation unit. The virtual power generation device model unit includes: a motor model unit; an AVR model unit; an angular velocity difference acquisition unit; and a power generator model unit. The control signal generation unit is configured to generate the pulse width modulation signal based on the current command value and an output current value from the power conversion circuit.
