Self-healing networks performance improvement by automated switching algorithm

This paper explores a methodology for performing automated switching on high voltage (11kV) distribution networks to restore supplies following fault trips using an algorithmic approach based on real-time tracing and analysis of the electrical network model held in the Network Management System (NMS). The approach offers a number of advantages over local automation and pre-configured switching schemes: ” A single algorithm to handle any network configuration. ” Impervious to network alterations. ” Reduced and simplified maintenance overhead of schemes. ” Comprehensive checks can be performed against the actual network diagram.
