Harmonics mitigation of industrial power system using harmonic blocking compensators

Abstract

This paper presents a passive harmonic blocking compensator (PHBC) for harmonic suppression and reactive power compensation in distribution systems. PHBC composed of a line series filter tuned to the fundamental frequency and a shunt passive filter. FORTRAN Feasible Sequential Quadratic Programming (FFSQP) is used as an optimization tool to find the proper sizing of parameters of the suggested filter for minimizing the supply current total demand distortion (TDD), where maintaining a given power factor at a specified range is desired. The optimal design of the PHBC, the contribution of the newly developed method and its feasibility are presented in two study cases.
