Dynamic reactive power compensator with harmonic reduction LKD

We present a family of dynamic compensators designed for compensation of inductive and capacitive reactive power with an additional function of distortion power compensation. The presented solution gives the possibillity of low-loss reactive power compensation as well as through the appropriate selection of options we can compensate for the selected harmonic. The filters have been used replacing traditional capacitor-choke batteries, raising the standard by filtering higher harmonics. We have gained a large reduction of the compensation system's own losse while reducing the amount of apparent power further reducing electricity charges.
