Title:
CONTROL DEVICE, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/092812
Kind Code:
A1
Abstract:
The control device according to an embodiment is a control device for a self-commutated converter connected to an AC system. The control device has a filter calculation unit, a coordinate transformation unit, and a converter control unit. The filter calculation unit calculates, on the basis of the voltage of each of the three phases of the AC system, a current target value for each of the three phases so as to obtain a transfer function based on the RLC components of an AC filter capable of suppressing the harmonics of a predetermined frequency band. The coordinate transformation unit transforms the current target value for each of the three phases calculated by the filter calculation unit to a first d-axis current target value and a first q-axis current target value. The converter control unit controls the self-commutated converter on the basis of a second d-axis current target value based on requested power and the first d-axis and q-axis current target values transformed by the coordinate transformation unit.
