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: : "Ben, My take is in-line with Brad. The OLTC is used strictly to keep the generators/inverters online through various voltage ranges to produce maximum kW and kVAR when required. The plant controller/AVR is the only control loop that manag...
Said: : "I would start with Mike Wells – here is the WECC audit team contact info:"
Said: : "Leland: Thanks for the example about multiple AVRs. I can see how that fits in this standard. Can you provide me the contact at WECC? Brad: That's a good angle/method for looking at this requirement. The word "external" does throw out m...
Said: : "We are currently go thru our yearly self-certification and in tables 1-4(a) thru 1-4(c) (for the different battery types) it states in the 18 month interval to "verify battery intercell or unit-to-unit connection resistance" and "verify b...
Said: : "I understand the confusion. The question is, does your AVR/Controller send signals to the capacitors to come on or off? If yes, then the AVR/Controller is the only controller managing your MVar loading. Do you use your LTC to manage MVar ...
Said: : "Hi Benjamin,   I have had a little exposure to this requirement, so I can chime in.  EA18.2 is pretty straightforward, you will need documented concurrence from the TOP for the control loop design.  To answer your other questions all tog...
Said: : "The SDT's Consideration of Comments at http://www.nerc.com/pa/Stand/Project%20200709%20%20Generator%20Verification%20%20PRC0241/Consideration_of_Comments_2007-09_PRC-024-1_2012Dec07_final.pdf is definitive in stating, "The standard is lim...
Said: : "Incidentally, the 0.90 pu value at the transmission bus should, in most cases, coincide with what your Transmission Planner and Planning Coordinator use for the acceptable steady-state (beyond 4 seconds) acceptable voltage levels during e...
Said: : "Just as one additional comment to add on to what Mr. Esmaily-Radvar pointed out- because the IEEE standard is for the equipment, the voltage referred to in C50.13 is at the generator terminals, while the voltage referred to in the PRC-02...
Said: : "In my opinion, "continuous" by IEEE means thermal equilibrium. In other words, my interpretation is that 0.9pu is a continuous value pass the 4sec. It might help to distinguish between protection boundaries versus equipment boundaries. PR...
Said: : "My interpretation, take it for what its worth, is that for frequency they use the term "continuous operation" and use a logarithmic scale so you must be able to continuously run inside those values. Now for the voltage, they do not use t...
Said: : "Excellent - thank you very much Bill!"
Said: : "During the development of the standard, it was discussed that the time frames outside of beyond those plotted were not part of the "no trip zone". The values shown in the tables were included to identify the corners of the curves which ...
Said: : "To Mr. Harbour's comment...I think so for including PSS's in the notification agreement process. Most PSS's become active and inactive automatically as the MW output changes (active with MW 10-15% MW capability and off below that valu...
Said: : "Response to Question 1: We work with multiple TOPs and they are generally not willing to provide long term changes to the voltage schedule they provide. We have been successful in obtaining start-up exemption, usually below 10% of namepla...
Said: : "Bill, I agree and we have that communication with the TOPs, however at least at one site, we have an issue for about an hour after we are producing and having to follow the 9 PM to 7 AM voltage schedule during the summer months with June ...
Said: : "Is there a benefit to clarifying that the start-up and shut-down provisions in R1 apply to Power System Stabilizers as well as AVRs. There seems to be a mismatch between R1 and R3. R1 mentions an alternate notification process for start...
Said: : "In lieu of obtaining a schedule specific to PV sites that cannot control the voltage when not generating (Mr. Collard's comment) and notifying the TOP daily, the TOP can offer relief for PV plants relative to the repetitive notification o...
