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: : "Thanks for posting those results Robert. Too bad you didn't get a better response, but as I expected, this requirement will be handled differently by different entities."
Said: : "NAGF CIP LIS Survey Summary.xlsx Attached are the results of the CIP Low impact Physical Security Survey. Thanks for your responses. In addition, I would like to ask the following questions: 1. How do you plan to restrict access to your...
Said: : "I forgot to mention in the initial post that I plan to share the results of the survey with the group."
Said: : "I hope everybody is have a great and safe 4th of July. I managed to get some responses on the WICF forum when this standard is relevant as it is a WECC variant. I thought I would summarize here and see what others suggests are. This stan...
Said: : "David L: I was looking through the PSS commission reports from GE and noticed they did mention "gain margin". Remembering way, way back to small-signal theory the gain margin is a value assigned to how far away from the instability point...
Said: : "David, I like your thought process.  However, the hang up might be on page 9 where it states: “It is now part of Measure M3 to show the field test results that led to the determination of the maximum practical gain.”  The 2002 PSS tunin...
Said: : "Dave, have you talked to your plants to see if the original commissioning documents provide this information? In working with one of my plants, they have documents from their commissioning that shows what the manufacturer determined to be...
Said: : "All: So it would appear that the "maximum practical gain" value needs to be determined. What does everybody think about using either PSLF(TM) or PSS/E(TM) to derive that value? You take your verified or re-verified dynamic model that y...
Said: : "John: Thanks for asking the questions and posting the replies. So from what I can gleam from the responses, a GO must have the actual data of the PSS including the maximum practical gain value--that is too bad given that most of our PSSs...
Said: : "Mr. Tom Alrich, Manager Enterprise Risk Services for Deloitte Advisory, has written a blog regarding this thoughts to these FERC questions. You can read via access to this site. http://tomalrichblog.blogspot.com/2017/06/ferc-asks-twoque...
Said: : "Hi All; The following are our questions and the response we received from WECC. It is not encouraging. Black text is ours, red is WECC's. Regarding VAR-501-WECC-3 WECC has stated during the standard development process that this new sta...
Said: : "Thanks David P. The problem I am having is that our PSSs were tuned long before this standard was considered and there is only mention of following the WECC guidelines in the tuning report. So according to your statement, that is proof t...
Said: : "David R, The standard provides a bit more details regarding the requirements on pages 8-10. Specifically, additional details associated with R3.3. It mentions that the "maximum practical gain" should be made during PSS commissioning. The...
Said: : "The previous WECC document would talk about a gain margin. Gain margin requires an accurate knowledge of the maximum PSS gain that would be at the brink of instability and nobody wants to find that gain in practice, during the field tests...
Said: : "Here are a few comments from our field engineer who performs PSS calibrations: There are two possible definitions I can come up with for maximum practical gain: 1) Gain a which the PSS becomes unstable. For a delta-f type PSS, I incre...
Said: : "Thanks for the responses. My understanding is that the idea of maximum allowable gain came from the thought that one should take the PSS to the point of small-signal instability (sustained oscillations) and that is the value for maximum ...
Said: : "I would start by asking Kestrel the basis for their statement. They have been very cooperative whenever I have asked them for help. If that doesn't work, the next step is to look in your manual or be ready to pay the PSS vendor."
Said: : "Hi David; We have sent questions to WECC regarding R3. What evidence is needed; is a statement that we meet the existing Criteria and tuning procedure sufficient; or a statement from the supplier that it meets R3? So far, no response. I...
