This Nodal Operating Guide Revision Request (NOGRR) provides more stringent protection and control requirements for all new Competitive Renewable Energy Zone (CREZ) 345 kV Facilities.
Reason:
This NOGRR provides requirements for the protection and control for the CREZ transmission system that supports the transfer of renewable energy reliably from remote areas to large Load centers. This NOGRR is aimed at achieving fault clearing within the voltage curve described in North American Electric Reliability Corporation (NERC) Draft Reliability Standard PRC-024-01, Generator During Frequency and Voltage Excursions (http://www.nerc.com/docs/standards/sar/PRC-024-1_Draft1_2009Feb17.pdf). The proposed revisions also address new NERC Planning (http://www.nerc.com/filez/standards/Assess-Transmission-Future-Needs.html) and Protection (http://www.nerc.com/docs/standards/sar/Project2009-07_Tech_Paper_Reliability_of_Protection_Systems_2009Jan20.pdf)standards currently under consideration.
