Various util ities have explored various ways to leverage IEC-61850’s flexibility. Th is presentation showcases real-world examples demonstrating how IEC-61850 can significantly address complex issues in existing substations with trad itional protection systems\, enabling additional functionality without the extensive wiring changes previously required.\n\nThis presentation detail s a practical application where IEC-61850 was used to resolve an existing problem and enhance system performance. The application involves five dist ribution lines connected to a common bus\, each line sharing poles for par t of the feeder. Multiple distribution lines on the same poles add complex ity to the protection system\, necessitating cross-interlock schemes and s taggered reclosing logic to maintain proper selectivity. While the partner ed utility has already standardized on a cross-interlock scheme using hard wired I/O and applies staggered definite-time delays for reclosing on each circuit\, this site predates this standardization\, so the hardwired I/O cabling was not installed.\n\nTo address this\, Burns and McDonnell and th e partner utility chose to adapt their cross-interlock scheme from hardwir ed I/O to IEC-61850 GOOSE for this site. This transition eliminated the ne ed for additional control cables and terminations on each device and enabl ed real-time sharing of fault current magnitude between feeder relays. Cus tom logic was also developed for each feeder relay to enable staggered rec losing based on fault current magnitude\, rather than a fixed delay.\n\nIn collaboration with the utility\, new cross-interlock and staggered reclos ing logic using IEC-61850 was implemented and rigorously tested in the Bur ns & McDonnell Atlanta laboratory to ensure it met performance expectation s. The successful results highlight the advantages of making such changes without additional wiring\, thus significantly reducing costs and implemen tation time. Moreover\, the programmable logic capabilities of IEC-61850 u nderscore its value in enhancing reliability and facilitating a smoother t ransition to a fully modernized grid.\n\nThis presentation will also inclu de a lab tour (the approach here will vary depending on audience size)\, a nd a brief demo of various approaches being taken in the industry\, with t he goal of highlighting the endless possible approaches that can be taken! \n\nAgenda: \n11:00am - 12:00pm - Presentation\n\n12:00pm - 1:00pm - Lunch and Networking\n\n4004 Summit Blvd.\, Suite 1100\, Atlanta\, Georgia\, Un ited States\, 30319 LOCATION:4004 Summit Blvd.\, Suite 1100\, Atlanta\, Georgia\, United States \, 30319 ORGANIZER:larhonda.julien@gatransmission.com SEQUENCE:28 SUMMARY:IEEE PES Atlanta Technical Talk - Innovation for the Future: Enhanc ing System Protection with IEC-61850 URL;VALUE=URI:https://events.vtools.ieee.org/m/485905 X-ALT-DESC:Description: <br /><p class="MsoNormal"><span style="font-size: 11.0pt\; font-family: 'Arial'\,sans-serif\; mso-fareast-font-family: 'Time s New Roman'\; color: black\;">The IEC-61850 communication protocol is gai ning recognition as the future of power system protection\, automation and control\, offering a transformative approach to substation design and ope ration.
