FIELD: electricity.SUBSTANCE: invention relates to electrical engineering. The arrangement of electric energy supply to a load through a filtering bus comprises at least two converters of voltage sources, each of them is connected in parallel to the filtering bus through an inductance coil and configured for joint loaded operation. Each converter is connected to a control unit (10) configured to control voltage (v) of the filtering bus at maintenance of dynamic control of the converter current. This control unit engages generation of two perpendicular intercrossing voltage vectors (v, v) of the filtering bus out of the filtering bus voltage as well as generation of the current vector (i, i) for each voltage vector of the filtering bus. Also the control unit uses multiplication of each current vector by the attenuation coefficient (D) common for all current vectors. Multiplication product (13) is delivered for subtraction of this result from the respective reference vector (v?, v?) of the filtering bus voltage.EFFECT: potential dynamic current control and current limitation.13 cl, 4 dwg |
