Fault detection, isolation and restoration (FDIR): A decentralized approach

Electric power distribution network is gaining more attention in order to supply reliable, efficient and safe power to the end users (e.g. industrial, business, and residential). With deployment of distribution automation applications, power utilities can not only achieve the performance goals, but also improve situational awareness, and reduce the financial penalties they incur due to system outages. This paper presents an overview of advanced distribution automation with focus on how a Fault Detection Isolation and Restoration (FDIR) solution can address some of the challenges faced in today's power distribution systems. After comparing various FDIR approaches,this paper presents various algorithms for the decentralized FDIR approach.
