An energy firm has launched a system that aims to boost the efficiency and reliability of the grid. 

The End-to-End Fault Detection, Isolation & Restoration (FDIR/FLISR) system, which US firm GE has launched, is a complete distribution automation solution that enables utilities to significantly improve the reliability of their distribution networks.

This solution is capable of detecting power system outage locations and automatically sectionalising and reconfiguring distribution circuits to restore power to as many customers as possible.

The FDIR/FLISR advanced distribution automation system can often reduce typical customer outage time from hours to under a minute as well as improve a utility’s SAIDI and SAIFI reliability indices.

The solution from GE includes the Multilin D400 DA, a substation-based FDIR system that can automate up to 20 distribution feeder circuits; the Multilin DGCS Switch Controller; the Multilin DGCR Recloser Controller; and the MDS Wireless Communication network, which seamlessly work together enabling easy deployment across the distribution network.

GE said: “This solution is very scalable and can be rolled out incrementally across the system providing utilities with the flexibility for staged deployments as their network requires. This distributed substation and field intelligence solution provides additional reliability with the ability to restore local parts of the network even when wide-scale problems such as loss of backhaul communications to the control centre occur.”

Grid and electrical infrastructure will be one of the many topics covered at BigSwitch Offshore Wind, a global wind event, which Renewable Energy Technology (RET) is sponsoring. The event, which is taking place in Glasgow on 26th and 27th June, aims to advance technological developments across the global offshore wind industry.
