Abstract

Large converters in applications of high-power industrial drives are the main harmonic sources in a power system. In this paper, the model for harmonic analysis of AC/DC power systems coupled by power electronic converters is proposed. The basic principles are that the operation cycling of the converter and sampling switching characteristics of the thyristors can be represented by logic switching and its eign equations. Two instances of harmonic calculation for a 6-pulse bridge converter and a 6/12-pulse converter are taken. The computed results are in good agreement with the measuring results. It is proven that the suggested method is more effective and accurate
