Simulation Calculation and Analysis of Single-Phase Faults in Distribution Networks

The phase component method can comprehensively and accurately characterize the electrical properties of asymmetrical components in power systems. In this paper, the mathematical model of the phase component method is used to describe the asymmetry of distribution network structural parameters and loads. On this basis, a comprehensive simulation calculation and theoretical analysis of single-phase grounding faults in distribution networks is carried out by using the comprehensive simulation calculation software NETOMAC, and the relevant conclusions of single-phase grounding faults in distribution networks are obtained, which provide a quantitative basis for the analysis of faults in distribution networks.
