PROJECT TITLE :

A Fortescue Approach for Real-Time Short Circuit Computation in Multiphase Distribution Networks

ABSTRACT:

This paper discusses the necessity for short circuit analysis in real-time applications of recent distribution networks and presents a brief circuit tool that builds on recent advances in Fortescue-based current injection power flow. The proposed short circuit computation (SCC) method is fundamentally based mostly on the symmetrical components transformation of 3-part, 2-part, and one-phase systems. Unlike the classical symmetrical elements SCC methodology that postulates a structurally symmetrical 3-section pre-fault network with balanced loading, the proposed technique accounts for multiphase networks that are comprised of three-section, 2-phase, and one-phase network elements; given a pre-fault power flow resolution, it requires a most of three current injection iterations to compute the short circuit current flow in the entire network. Numerical results show that the Fortescue SCC approach with multiphase lines exhibits vital computational performance improvement on large-scale networks as compared to classical SCC in phase coordinates.
