It provides fast channel-independent tripping for a portio n of the protected line (Zone 1)\, it detects faults for the entire line i n pilot protection schemes (Zone 2)\, and it provides step distance backup protection for the line and surrounding system. In line protection\, dist ance elements are our go-to solution. Wind-powered generators and inverter -based sources considerably change the fault current characteristics in th e electric grid. These sources challenge several protection fundamentals t hat used to serve us well in the days of large synchronous generators. Our industry seems to insist on keeping present distance protection designs a nd looks for a patch\, a tweak\, or an add-on that would make the present designs work. We struggle to find and justify those patches because of the complexity of the problem\, the lack of a universal fault response from u nconventional sources\, and proprietary relay designs. Even when we find a nd apply tweaks\, we slide back into using simulations to prove protection schemes and their settings on a project-by-project basis. This talk shows that a solution lies in the direction opposite of the reflex to add a fix based on the details of the problem. Instead of adding more logic based o n the exact nature of the problem\, we simplify the present design and mak e it work under worst-case assumptions. Working with worst-case assumption s about the problem frees us from having to know the exact source characte ristics and from insisting on a universal fault response from the sources. When pursuing this path\, we will rediscover some older distance protecti on concepts and approaches that our industry has forgotten about.\n\nCo-sp onsored by: IEEE Power and Energy Socieity\n\nSpeaker(s): Bogdan Kasztenny \, \n\nAgenda: \n4:00 pm IEEE Announcements\n4:02 pm Introduction of Speak er\n4:04 pm Presentation\n4:50 pm Q&A\n\nVirtual: https://events.vtools.ie ee.org/m/326558 LOCATION:Virtual: https://events.vtools.ieee.org/m/326558 ORGANIZER:mike.brisbois@ieee.org SEQUENCE:8 SUMMARY:Angle of distance elements in applications to IBR/Wind dominated gr id URL;VALUE=URI:https://events.vtools.ieee.org/m/326558 X-ALT-DESC:Description: <br /><p>Distance protection has been a valuable to ol in our toolbox for over 70 years.
