A decoupled reference generation algorithm for harmonic, reactive power and current unbalance compensation in three-phase systems

摘要

In this paper a decoupled reference generation algorithm for harmonic, reactive power and current unbalance compensation is presented. The proposed method has the advantage that it generates the reference for compensation which is immune to supply voltage distortions and ensures that the source has to deliver only the fundamental active component of the load current. It also ensures that the source current after compensation is balanced and at unity power factor. Matlab simulation of the proposed method and a comparison of reference generation by the existing methods have been done and presented in this paper for establishing the validity and practicability of the proposed method.
