Abstract

In this paper, the basic mechanisms of generation and flow of harmonic signals in electric power networks are discussed. With regard to generation, the unbalanced operating condition of a six-pulse converter is studied. Guidelines which are applicable in the general case are obtained. With regard to flow of harmonic signals, a new relationship between distortion voltamperes (D) and total harmonic distortion (THD) is derived. This relationship is very similar to the P/δ and Q/ |V| relations which are well known in electric power flow studies.
