SynchroGrid verified that all generator types that Pattern has in its system complied with the NERC PRC-019-2 standard, making sure the limiters operated first before the relays, as per standard recommendations.

Services included:

  • Coordinating the voltage regulating system controls, including in-service limiters and protection functions, with applicable equipment capabilities and settings of the applicable protection system devices and functions
  • Setting the in-service limiters to operate before the protection system of the applicable facility in order to avoid disconnecting the generator unnecessarily
  • Setting the applicable in-service protection system devices to operate in order to isolate or de-energize equipment to limit the extent of damage when operating conditions exceed equipment capabilities or stability limits
  • Relaying evidence that the facility coordinated the voltage regulating system controls, including in-service limiters and protection functions, with the applicable equipment capabilities and settings of the applicable protection system devices and functions, in compliance with PRC-019-2
