Status:
A final ballot for PRC-027-1 – Coordination of Protection Systems for Performance During Faults concluded 8 p.m. Eastern, Wednesday, October 14, 2015. The ballot results can be accessed via the links below. The standard will be submitted to the Board of Trustees for adoption. Once TOP-009-1 is approved by ballot and adopted by the Board of Trustees, PRC-027-1 will be filed with the appropriate regulatory authorities in conjunction with TOP-009-1 to achieve the complete retirement of PRC-001-1.1(ii).

Retirement of PRC-001-1.1(ii)
In conjunction with Project 2007-06.2 Phase 2 of System Protection Coordination, NERC is proposing the complete retirement of PRC-001-1.1(ii). In Phase 2, Requirement R1 is being incorporated into the proposed Reliability Standard TOP-009-1. Requirements R2, R5, and R6 are proposed for retirement as the reliability objectives of those requirements are addressed by other TOP/IRO standards. See the Mapping Document on the Phase 2
project page for an explanation of how the reliability objectives of Requirements R1, R2, R5, and R6 are addressed. The remaining two Requirements R3 and R4 of PRC-001-1.1(ii) are addressed by PRC-027-1. See the Project 2007-06 System Protection Coordination Mapping Document below. The complete retirement of PRC-001-1.1(ii) is contingent upon the approval of Reliability Standards PRC-027-1 and TOP-009-1. NERC is proposing the retirement of PRC-001-1.1(ii) in the implementation plans associated with both projects.

Background
Project 2007-06 System Protection Coordination originated in 2007 to address directives from FERC Order 693 and other issues identified by the System Protection and Control Task Force pertaining to PRC-001. The System Protection Coordination Standard Drafting Team (SPCSDT) has developed Reliability Standard PRC-027-1 with the stated purpose: “To maintain the coordination of Protection Systems installed to detect and isolate Faults on Bulk Electric System (BES) Elements, such that those Protection Systems operate in the intended sequence during Faults to address all of the outstanding issues. PRC-027-1 clarifies the coordination aspects and incorporates the reliability objectives of Requirements R3 and R4 from PRC-001-1.1(ii).

Draft 5 of PRC-027-1 was posted for formal comment and ballot from April 1 – May 15, 2015. The standard received affirmative votes totaling 39.63 percent. The drafting team appreciated the feedback industry stakeholders provided and has incorporated many of the suggested revisions into draft 6 of the standard. In accordance with section 4.13: Additional Ballots of the Standards Process Manual, the drafting team is not providing written responses to the comments with this posting because significant revisions to the standard were made and an Additional Ballot will be conducted.

Draft 6 of PRC-027-1 consists of three proposed requirements.
 
Requirement R1 mandates that an entity establish a process for developing new and revised Protection System settings for BES Elements to operate in the intended sequence during Faults; and stipulates certain attributes that must be included in the process.
 
Requirement R2 mandates that an entity periodically perform Protection System Coordination Studies and/or compare existing Fault current values to established Fault current baselines for Protection Systems applied on BES Elements that are identified as being affected by changes in Fault current. The applicable Protection System functions are identified in Attachment A.
 
Requirement R3 mandates that an entity utilize the process established in accordance with Requirement R1.

 

 

 


Standard(s) Affected:
PRC-027-1 - System Protection Coordination, Retirement of PRC-001-1.1(ii) - System Protection Coordination


Purpose/Industry Need

Coordinated Protection Systems enhance reliability by isolating Faults, thus reducing the risk of BES instability or Cascading and leaving the remainder of the BES operational and more capable of withstanding the next Contingency. When Faults occur, properly coordinated Protection Systems minimize the number of BES Elements removed from service and protect equipment from damage.
