Passive-component-based reactive power compensation in a non-sinusoidal multi-line system

In this paper, a generalized compensation method of reactive power applicable to a multi-line system under non-sinusoidal conditions is studied. The compensation is confined to parallel compensation with passive components, i.e., inductors and capacitors. If the required reactive currents containing harmonics are given, an L–C network, composed of passive components and generating the required reactive currents, is synthesized. The proposed L–C network is composed of a star-connected part and a circular connected part. It is shown that the proposed method is comprehensive, easy, and systematic to apply.
