Abstract
A control device includes a generator simulating unit to generate a phase of output voltage of a power converter by simulating characteristics of a synchronous generator, a first voltage command generating unit to generate a first voltage command value of output voltage of the power converter so that an AC voltage of a power grid attains a target voltage, a setting unit to set an overcurrent level, and a second command generating unit to generate a second voltage command value by limiting the first voltage command value based on the overcurrent level. The control device further includes a signal generating unit to generate a control signal for the power converter, based on the phase generated by the generator simulating unit and the second voltage command value.
