Project Description
In order to ensure NERC compliance, an experienced engineer was required to review relay settings for 20 generation sites and continually support the client maintaining compliance whenever settings were updated.
Outcome
PRE has been the lead engineer for continued support of relay settings review for about 20 generation sites against NERC PRC-19 (voltage controls vs effect on loss of excitation relays), PRC-24 (over/under voltage/frequency relay sensitivity), and PRC-25 (generator system relay loadability) requirements versus facility relay settings. PRE also provided a relay training class for necessary personnel of the client, per PRC-01, describing the purpose of each relay and the types of events that could cause relays to trip.
