WAYS OF P-Q THEORY MODERNIZATION FOR WORK IN NON-SINUSOIDAL UNBALANCED VOLTAGE CONDITIONS

Abstract

Two different techniques of P-Q instantaneous power theory mathematical apparatus modernization for shunt active filters are analyzed. Both techniques are equal in nature while different in implementation. The modernization concepts introduced allow correcting imperfection of the P-Q theory under conditions of unbalanced and non-sinusoidal supply voltage systems.
