Abstract:
1. A system for compensating harmonic components or a reactive power of an electrical network, the system comprising: a measurement unit configured to measure an electrical quantity to be compensated; a control unit configured to determine harmonics contents or a reactive power need of the measured electrical quantity to be compensated as well as to determine, as relative values, desired values corresponding with the harmonics to be compensated or the reactive power to be compensated, wherein the desired value of each harmonic amplitude to be compensated is between 0 and 100 percent; a plurality of compensation units configured, responsive to the desired values provided by the control unit, to generate harmonic components or reactive power according to the desired values given as relative values, and each compensation unit is configured to proportion a relative-value compensation instruction to a free compensation capacity; and a communications connection configured to communicate the desired values determined by the control unit to the plurality of compensation units.
