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: : "The drafting team, added R4 to prevent someone from verifying a model under R2, then changing equipment that affects the dynamics (say within 1 year), and then not revising the model for up to 9 years on the repeat verification. Someone...
Said: : "For MOD-027, we had changes before initial verification testing and followed the process that Bryan Dixon described. The RSAW question that David Lemmons referenced prompted us to interpret R4 would be triggered without a verified model."
Said: : "My understanding: to meet R4, you need to provide revised model data (from OEM design data and unverified model) to TP to update their model database and provide plan (future schedule to perform model verification as per R2 schedule) with...
Said: : "I would caution that people may be reading the wording "revised model", in the requirement and assuming that it means a "verified model". Please remember that theoretically all generators will provide information as they are being designe...
Said: : "We had no plans on testing for R4 compliance if R2 was not met i.e. the unit has not been tested as yet. Our thought process was if a units model has been tested and sent to our TP then we would follow the R4 compliance requirement. Havin...
Said: : "When we made changes to the unit which met the conditions of MOD-026 R4 we performed a MOD-026 verification test and submitted the data. We used the verification to meet R2 as well."
Said: : "My opinion is that until the original model has been verified, a change in the model (revision) due to control system work doesn't make sense, because the model has not yet been verified."
Said: : "Douglas, We at Dominion Energy use what the our regional Transmission Planner (PJM) reports to us in a report we request annually. Here in Virginia, we are the TO, however PJM is the Transmission planner, among other things. In our case ...
Said: : "Bryan, You have that backwards. There are the P values in the calculations. P = PF*Generator_Nameplate (this is used to calculate Q) P_reported = The gross real power reported to the Transmission Planner. These are two differen...
Said: : "We use installed and authorized generator net values as reported to the TP with auxiliary loads added back in to get the generator gross value for PRC-025-2 calculations. This value is typically always less than the generator nameplate M...
Said: : "Net Megawatts as reported to the TP. I have found that transmission only cares about what you can get over the fence that they then have to deal with. Dave"
Said: : "Gerry:     Here is an estimate for you…. (per installation)                Equipment           $25,000                Installation          80 man-hours                Configuration     8 man-hours   Best Regards,   Bill From: Gerry Ad...
Said: : "We have installed them for roughly $80k per DDR. Includes engineering/design, equipment, installation, and training."
