<p>An arrangement for supplying electric power to a load through a filter bus comprises at least two Voltage Source Converters connected in parallel to said filter bus through an inductor each and configured to share said load. Each converter is associated with a control unit (10) configured to regulate the voltage ( v f ) of the filter bus while maintaining dynamic control of the current from the converter. This control unit involves production of two perpendicularly-intersecting filter bus voltage vectors ( ½ fx , ½ fy ) from the filter bus voltage and the control unit involves production of a current vector ( i kx , i ky ) for each said filter bus vector. The control unit also involves multiplying of each said current vector with a droop coefficient common to all the current vectors. The result of this multiplication is sent to means (13) for subtracting this result from the respective filter bus voltage reference vector ( ).</p> |
