Abstract

Employing bipolar dc distribution systems introduces the possibility of imbalance in the system. To analyze these systems it is crucial to create novel modelling techniques. This paper presents a method to decompose dc distribution systems into symmetrical components. The presented method simplifies the analysis of balanced, unbalanced, and fault conditions of bipolar dc distribution systems. Equivalent circuits for several network components in the symmetrical domain are derived and are shown to be independent under symmetrical conditions. Furthermore, a dynamic analysis is performed in the symmetrical domain showing that the method simplifies the analysis of dc distribution systems. Additionally, the symmetrical domain equivalent circuits of several fault conditions are derived.
