Title:
POWER CONVERSION DEVICE AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/058196
Kind Code:
A1
Abstract:
A current suppression control unit (100) calculates a correction amount (ΔVmg) of a reference voltage command value (VmgDB) for operating a power converter as a voltage source and sets the amplitude value (Vmg*) of a voltage command value on which the correction amount (ΔVmg) of the amplitude value (VmgDB) of the reference voltage command value is reflected. The correction amount (ΔVmg) is set in order to make the amplitude value (Vmg*) of the voltage command value smaller than the amplitude value (Vmgbs) of the reference voltage command value in accordance with the decrease of AC voltage (Vsys) at an interconnection point.
