Method and system for programming and implementing automated fault isolation and restoration using sequential logic

摘要

A method and system for programming and implementing automated fault isolation and restoration of high-speed fault detection of circuits in power distribution networks using sequential logic and peer-to-peer communication is provided. High-speed fault detection of circuits in power distribution networks uses protective relay devices (14) segmenting a distribution line (11) having Intelligent Electronic Devices (IED) (22) associated with switching devices (20) communicating peer-to-peer via a communication system (30) to provide fast and accurate fault location information in distribution systems with sequential logic.

主权项

1. A method for facilitating automated fault isolation and service restoration in power distribution networks having protective relay devices, comprising:
programming into each of the protective relay devices a plurality of operational sequences that when executed control associated switching devices when a fault detection element identifies a faulted section in the network, wherein each operational sequence is selected for execution based on system status information and fault information; sharing system status information and fault information via peer-to-peer messaging between protective relay devices via a high speed communication system; and executing an isolation operation comprising a proper operational sequence based on system status information and fault information shared between protective relay devices to isolate the faulted.
