2007

• PRC-002-NPCC-01 – Disturbance Monitoring – November

2010 – Retired August 2016

• PRC-002-2 – Disturbance Monitoring and Reporting

Requirements – November 2014

• Directory 11 - Disturbance Monitoring Equipment Criteria –

October 2016

History or evolution of the Directory

• PRC-002-1

– PRC-002-1 required Regional Reliability Organization to establish disturbance monitoring requirement – A-15 and PRC-002-NPCC-01 served those functions

• PRC-002-NPCC-01

– NERC encouraged development of regional standards due to delays developing PRC-002-2 – Incorporated and expanded on most of the criteria in A-15 as Requirements in the Regional Standard with Measures , Compliance Monitoring Process and Violation Severity Levels – Increased maintenance Requirements – Expanded requirements for GO’s

History or evolution of the Directory

PRC-002-2

• Contained specific requirements, no longer delegating to the RRO.
• Most requirements were very similar or identical to the PRC-001-

NPCC-01 requirements.

• The Implementation Plan required NPCC to address three specific

requirements that were in conflict with PRC-002

• Rather than revise PRC-002-NPCC-01 to address those

requirements, it was felt that it would be too burdensome to have two NERC Standards with slightly different requirements both subject to auditing.

• Similar to retirement of Directory 3 when PRC-005-4 was approved.

Directory 11

• Retained applicability to all BPS TO and GO facilities for SER
• Retained applicability to all BPS TO facilities for FR

– For facilities identified in PRC-002 and as BPS, must meet more stringent

• f both documents

– Includes future BPS facilities

• Removed DDR requirements because these were covered in PRC-

002

• Removed most maintenance requirements
• Incorporated three NPCC Guidelines documents consistent with

NPCC document migration and to retain the body of knowledge

• Incorporated three NPCC Guidelines documents consistent

with NPCC document migration

– Appendix A – Guide to Time Synchronization of Substation Equipment (Guideline B-25) – Appendix B – Guide for Application of Disturbance Monitoring Equipment (Guideline B-26) – Appendix C – Guide for Generator Sequence of Events Monitoring (Guideline B-28)

Key differences from PRC-002

– Applicable facilities, not all BPS facilties covered by PRC-002 – SER Requirements

• PRC-002 SER for circuit breakers only
• D11 SER for circuit breakers, protective relays and teleprotection

keying and receiving – Elements

• PRC-002 – Transmission Lines and Transformers w/low side >100kV
• D11- Above plus Shunt capacitors and reactors, Dynamic VAR

devices and HVDC terminals, Line interconnecting BPS GSU’s

Key differences from PRC-002

– Recorded quantities

• PRC-002 – Three Phase –to-neutral voltages and Three phase

currents and residual currents

• D11 above plus polarizing voltages and currents and frequency

– Trigger Settings

• PRC-002- Phase and and residual overcurrent and phase
• vervoltage, no setting specified
• D11- Phase current =< 1.5 pu of secondary current rating, Residual

current = 0.2 pu secondary current, phase voltage 0.85 pu.

Key differences from PRC-002

– Recording lengths

• PRC-002 – Pre-trigger 2 cycles and minimum total record 30 cycles
• r pre trigger 2 cycles, 3 cycles post trigger and final cycle
• D11- Pre-trigger 2 cycles and minimum total of 1 second

– D11 requires monitoring time synchronization or monthly verification – Ability to determine current zero
