Welcome to the North American Generator Forum


The North American Generator Forum (NAGF) was founded in 2009 as a vehicle for generator owners and/or operators to address issues related to registration, compliance, standards development and other NERC-related topics. In 2013, the North American Generator Forum, Inc. became a non-profit, dues-based corporation.

We provide entities who are generator owners and operators in North America a means to collaborate and communicate with FERC, NERC, the Regional Entities, the Canadian Provinces and other organizations with missions similar to ours, with the ultimate goal of improving the reliability of the bulk power system.

RECENT ACTIVITY

Said: : "David, Thanks for responding - I had lost track of this -I figured I wasn't going to get any responses. Actually we are applying distance backup overload protection rather than 51V, so we are looking at 1a/b/c of Table 1 rather than 2a/...
Said: : "I think the issue is in the wording of Requirement 1 where it says "....shall apply settings that are in accordance with PRC-025-1- Attachment 1.." From a compliance standpoint it seems to limit the options for achieving the desired resul...
Said: : "Carl: You mention generator back-up stator over-current protection. So I am going to assume you are looking at options 2a, 2b, 2c or 3 for setting the over-current relay on a synchronous generator--is this correct? My understanding of t...
Said: : "Nick, To date we have had no volunteers to present for a PER-006-1 webex. So, I would like to make the request again. Is there anyone in NAGF willing to share their best practices that they are using for their PER-006-1 training? Pl...
Said: : "Brad: Thanks. I love these discussions too. Glad we have this forum to share info and challenge each other. It is true that other Reliability Standards include more equipment; and, while a solid maintenance program for all equipment is e...
Said: : "Bradley, Yea - I agree. Normally that breaker failure relay will trip more than the individual feeder aggregation. I just wasn't sure on this particular configuration, it is possible that they have a distribution feeder breaker and then a...
Said: : "Thanks Andrew, I keep missing that point. I agree with your statement: Either way in situation #1 - the relay itself would not be considered BES item, but the breaker failure lockout relay would be only if it trips generation greater than...
Said: : "Section 4.2.5 of Facilities. "Protection Systems and Sudden Pressure Relaying for generator facilities that are part of the BES, except for generators identified through Inclusion I4 of the BES definition" The reason why they make this...
Said: : "Andrew, How exactly does PRC-005 exclude I4?"
Said: : "My interpretation would be that due to the definition of I4 inclusion - if you're facility is below 75 MVA total aggregated and interconnects below 100kV (which it sounds like it is) - then your site overall is a non-BES facility. Is the ...
Said: : "Michelle, Do you have any update for the PER-006-1 webinar described above? Do you have an anticipated timeline as to when this will occur? -Nick"
Said: : "My opinion. I love discussions like these. A couple of questions. PRC-024 requires voltage and frequency ride through. Do you have these UF, OF, UV, and UV settings on your feeder circuit breakers? Not only do we evaluate the feeder brea...
Said: : "Shivaz, for clarity the BES / non-BES is determined using the Inclusion I4 language. The BES breakers are included because they are part of the system designed for delivering 75 MVA. I4 - Dispersed power producing resources that aggregate...
Said: : "Without details on the BES determinations for the scenarios listed below, NYPA SME believes that the lockout relay and DTT equipment should be considered since they trip/isolate BES element."
Said: : "Bill, thanks for the reply. I agree with your analysis as it applies to a traditional generating station. The key difference here is both situations are distributed generation sites. So, 4.2.5.1 would not apply: 4.2.5.1 Protection Systems...
Said: : "My opinion... For Situation 1...If the breaker tripped by the breaker failure is the main generator breaker for the 20MVA plant, I agree it is not in scope of PRC-005. If the breaker tripped by the breaker failure is part of the BES net...
Said: : "I'm inclined to agree with your analysis but it would be interesting to hear some Protection Engineers chime in."
Said: : "At the last annual meeting, Tom Carpenter from TVA presented on PRC-005-6 in reference to Battery Testing. It was a great presentation. Unfortunately I cannot find my notes. The presentation is not posted because it was copyright material...
Said: : "We have been using a Megger BITE3 for our battery testing with varying success. Sometimes we get errant readings mostly due to poor connections with the test set leads. I think this is a pretty common problem. We are going trying several ...
