The optimal passive filters to minimize voltage harmonic distortion at a load bus

A method is presented for finding the optimum fixed inductance-capacitance combination to minimize voltage harmonic distortion at a load bus where it is desired to maintain the displacement power factor at a desired level constraining the compensator values, which would create resonance conditions, and the manufacturers´ standard values for power shunt capacitors according to IEEE Standard 18-2002. A comparison study of using the constraint, holding either the displacement power factor or the power factor at a desired value, is done. Finally, the contribution of the newly developed method is demonstrated in six examples taken from existing publications.
