CONTROL DEVICE AND POWER CONVERSION DEVICE

A control device (10) includes a generator simulating unit (153) to generate a phase of output voltage of a power converter by simulating characteristics of a synchronous generator, a first voltage command generating unit (155) to generate a first voltage command value of output voltage of the power converter (2) so that an AC voltage of a power grid (2) attains a target voltage, a setting unit (157) to set an overcurrent level, and a second command generating unit (159) to generate a second voltage command value by limiting the first voltage command value based on the overcurrent level. The control device (10) further includes a signal generating unit (103) to generate a control signal for the power converter (110), based on the phase generated by the generator simulating unit (153) and the second voltage command value.
