The NAGF has moved!

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.

Said: : "I spoke with GE, we have an ongoing exciter replacement project with them, when the WECC wording came out. They were concerned, relating what Ted says about preferred gain, and contacted WECC about it. WECC's response was to start a SAR...
Said: : "The WECC Standards Development Procedures permit SARs to be submitted for revision or interpretation on the regional reliability standard. See page 6 of https://www.wecc.org/Reliability/WECC%20Reliability%20Standards%20Development%20Pro...

Said: : "NAGF, Back in the EPRI Power Plant NERC Standards days, ETAP came in and made a presentation on using the ETAP tool to help with NERC Standards activities and plant config control. I've attached the presentations made then. I have su...

Said: : "Bill's outlook on PRC-005-1 applicability could be traced to the NERC's White paper having cited Protection Systems "of" GSUs and aux transformers (i.e. the line-ups shown next to this equipment on the one-line diagram), while it includes...
Said: : "Here is a slightly different interpretation for PRC-005-1, -2, and -6:   The protection system elements contained within excitation control systems is there to provide protection for the generator.    It is not protection for the excitati...
Said: : "All, As mentioned on the call last Friday, one of our member companies has done a deep dive to determine when the protective functions of AVRs first came to fall under PRC-005. Below is their interpretation. Does anyone see it differently...
Said: : "YES! Ameren would like to participate in a Peer Review through the NAGF. I will look at which standards we are interested in reviewing this week, and respond to this thread shortly!"
Said: : "I have created a recurring weekly meeting to draft the next communication to NERC on this topic (SAR or implementation guidance?). The first meeting will be held this Friday, March 22nd at 1PM EDT, chaired by Alison MacKellar. See the Gro...

Said: : "A clarification is needed in that the expression, "trip the unit," does not appear in PRC-005-6, which instead applies to devices that "trip the generator either directly or via lockout or auxiliary tripping relays." A V/Hz relay in the ...
