Advanced Control Systems' Centrix™ Feeder Automation Helps Pennsylvania Utility Deal with Transmission Outages

Wednesday, Feb 17, 2016

Advanced Control Systems (ACS), a global provider of smart grid automation technology, is proud to announce that Ryan R. Meller, Manager of Technical Services at Northwestern Rural Electric Cooperative, is presenting how his utility has leveraged the ACS Centrix automation solution to dramatically improve reliability on its system. Mr. Meller will present his paper, entitled: "Tackling Source Transfers and FDIR on the Distribution Grid", at 10:30 a.m. to 11:30 a.m. on Thursday, February 18 in the Gallery 1 Room at the New Orleans Marriott.

"The Centrix solution has been a great tool for our cooperative, helping us reduce outage durations significantly through automatic source transfers upon loss of power supply," says Meller.  The system also enables Northwestern REC to automatically isolate feeder faults and restore customers upstream and downstream where multi-feeder ties exist.  This is made possible through the ACS Fault Detection, Isolation and Restoration (FDIR) application running on Centrix.

"Centrix is a field-proven solution for self-healing feeder automation," says Rob Sadler, ACS Director of Product Management.  "Whether delivered on Centrix or as part of the PRISM™ Advanced Distribution Management System (ADMS), ACS customers have now deployed our FDIR application on thousands of feeders worldwide. We value the trust that NWREC and all ACS customers place in us to help reduce outage times for their customers and to keep their networks operating more reliably and efficiently."  

In his TechAdvantage paper presentation, Mr. Meller will discuss how NWREC uses the Centrix platform to automatically transfer as much of the interrupted load as possible within one minute of the loss of power supply, or in the event of a permanent fault condition that occurs on the feeder.  The restoration takes place without the need for operator intervention, utilizing real-time load flow calculations and automated sectionalizing devices on the feeder.
