Graph traversal-based automation of fault detection, location, and recovery on MVDC shipboard power systems

This paper describes a graph traversal-based method for automating system-wide programming of differential fault protection and generation of fault isolation steps in MVDC shipboard power systems (SPS). Automation is highly desired due to the increased complexity of isolating faults using disconnect switches rather than breakers. The method in this paper describes the derivation of a graph abstraction from the electrical system that is then used for computing a minimal but sufficient isolation sequence consisting of commands issued to breakers and switching converters.
