Abstract
A method and apparatus for the static compensation of reactive power using controlled reactive power converters having control variables derived from the phase load currents in which the phase load currents are converted into a line frequency oscillation and two rotating current vectors derived from each of the line frequency components, with the current vector components then transformed into d-c quantities by addition to a system vector to form a co-rotating and counter-rotating vector, from the components of which control variables of the reactive power converter are formed.
