SEL is releasing a new software solution for automating fault location, isolation, and service restoration (FLISR). The new solution is part of the SEL Distribution Management System (DMS) suite of wide-area control applications designed for distribution systems. DMS currently includes FLISR and DMS Designer, with more applications coming soon.

FLISR is a solution that reduces customer outage times during a permanent fault. It continuously monitors breakers, reclosers, and switches for a permanent fault

and takes over after any involved protection is finished. FLISR opens switching devices to isolate the faulted area and uses adjacent sources to restore power to as many customers as possible. FLISR supports any circuit breaker, recloser, or switch control that uses the DNP3 protocol.

DMS Designer allows you to configure and test your system via a web-based interface. It is simple to use and allows you to easily scale to a large distribution system. The DMS suite does not require complicated modeling software, such as Geographic Information System (GIS) software, to function all it requires is a distribution feeder topology.

Its graphical interface and integrated simulator allow you to build and test your system in minutes. Once tested and deployed, the feeder configuration transforms into the live view in the FLISR application, providing you with at-a-glance status information in the web browser.

DMS software runs as secure, container-based applications on SEL Blueframe, a specialized software platform for operational technology (OT) systems. Blueframe can be deployed on SEL's rugged computing platforms or virtualized on other server-grade hardware.

Try SEL's new FLISR solution for yourself at IEEE T&D. Lead product developer Bryan Fazzari will be onsite providing interactive demos of the new solution, including how to design a FLISR system and simulate it in real-world scenarios.
