Status:
The standard drafting team (SDT) finished the
first draft of the revised standards and they were posted for a 45-day
comment period from September 11 through October 26, 2009. The SDT is
responding to comments and will address the Standard Committee directive
regarding the "supplemental SAR” that proposes expanding the scope of
already approved work to address coordination of protection within an
entity’s footprint.
Purpose/Industry Need:
Protection system coordination is an absolute necessity for the North
American electric system to operate properly.
PRC-001 is a Version 0 standard, and was translated from an
operating policy that was appropriate in an era of voluntary
compliance.
The Version 0 standards and recent updates were put in place as a
temporary starting point to start up the electric reliability
organization and begin enforcement of mandatory standards.
However, it is important to update those standards,
incorporating improvements to make the standards more suitable for
enforcement.
Both FERC (within Order 693) and the SPCTF (in their report on PRC-001)
identified significant shortcomings in the existing standard.
The purpose of standard PRC-001-1 — System Protection Coordination
should remain “To ensure system protection is coordinated among
operating entities.”
The standard should be revised to:
-
Assure that Protection System application and performance issues are
coordinated among all related entities.
-
Correct the applicable entities within the standard to reflect the
actual functional responsibilities, as described in the NERC
Functional Model.
-
Incorporate other general improvements described in the standards
development work plan and from other sources.
-
Address directives received from ERO regulatory authorities.
