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.

RECENT ACTIVITY

Said: : "All, Here is NERC's response to our questions. I think we should get a call together to discuss further, and potentially develop additional questions or clarifications. -Mike Gabriel NERC Engineering and Standards technical responses are...
Said: : "This question caused a lot of discussion at WECC and NERC. In November, I got a final answer from James Hanson at WECC: "This has been a fun scenario to talk through amongst our group. Strong feelings on both sides, but we ultimately ...
Said: : "I will modify my comment to state the NAGF requests the opportunity to review this prior to it being completed and send it in."
Said: : "Thank you everyone. Your insights were very helpful. I'll update this post once NERC comes back with a response or additional questions. -Mike"
Said: : "In response to NERC's clarifying questions, most if not all AVR designs incorporate protective functions paired with corresponding limiting functions which may or may not be configured to trip the unit. However, if the sensing inputs to t...
Said: : "in your experience, are generator owners using AVR protective functions as an alternative to traditional protection systems?" not typically as an alternative for the 'traditional' elements but yes often for field current protection. Ther...
Said: : "Mike: Addressing your questions... Does anyone have any AVR OEM documentation they are willing to share? We are willing. Most of the AVR equipment vendors openly describe the protection system functionality that is optionally available w...
Said: : "Comment to Chris Schaeffer's on possible group comment: I think some commenting is appropriate to the subject document and to the PRC-019 SAR in development. Forcing application of PRC-019 to the entire plant design and performance wa...
Said: : "What kinds of PRC-005 related testing are you doing? Are you testing DC trip circuits related to the AVR? Are you verifying settings? Inputs? I don't know much about AVR, so I'm trying to relate this to protective relays. Thanks."
Said: : "It is in our experience not unusual for AVRs to contain programming that will trip the generator breaker, especially for V/Hz. This is typically a supplement to traditional generator relaying, not an alternative. We consider these lines...
Said: : "Hi everyone,   It is mentioned on page 6/11 of PRC019-2 standard that “inverter over current limit and associated protection functions” could be included as a part of PRC-019-2 coordination assessment. In my opinion, this implies that on...
Said: : "I am concerned that this document extends the applicability of AVRs and DCS controllers that have tripping functionality into this standard. These are not currently defined within the context of the PRC-005 protection system definitions ...
Said: : "All, We have received a response back from NERC, which asks two clarifying questions: "We are supportive of the SERC position regarding AVR protective functions. I will be meeting with our Regional Entity Compliance staff next week gain t...
Said: : "things to consider here. If the Sudden pressure relay trips the generator's 86 is a part of the protective system (understanding that it does not meet the definition) why would NERC add this device to the PRC-005 requirements That being...
Said: : "Thank you Brad."
Said: : "Thanks for the responses. Sorry, I wasn't clear in my question. Let me try again. I'm not asking about applicability of blackstart units to PRC-019 and other Standards. Section 1.4.4 of the guidance states "Blackstart generators are any g...
Said: : "The statements, "The overexcitation capability curve for the GSU should be obtained from the transformer OEM or test reports," and, " This curve [generator over-excitation capability] should be obtained from the generator OEM," are highly...
Said: : "Ref. Dave Gordon's question, this issue was raised when PRC-019 was balloted; see for example pp. 19-20 of the SDT's Consideration of Comments at https://www.nerc.com/pa/Stand/Project%20200709%20%20Generator%20Verification%20%20PRC0241/Co...
Said: : "Readings can be taken on the high side or the low side of the GSU, as stated in the standard; but, whichever way one goes, voltage and current need to be measured at the same location (per R6.1 and 6.2). The choice of location is therefo...
