Directory 11 Regional Reliability Reference Directory # 11 Disturbance Monitoring Equipment Criteria Presented to: Joint Meeting NPCC TFSP& WECC RWG September 2018 Tony Napikoski Principal Engineer – United Illuminatiing/Avangrid 9/13/2018 1

Directory 11 History or evolution of the Directory • PRC-002-1 – Define Regional Disturbance Monitoring and Reporting Requirements – August 2006 • A-15 - Disturbance Monitoring Equipment Criteria – August 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 9/13/2018 2

Directory 11 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 9/13/2018 3

Directory 11 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. • 9/13/2018 4

Directory 11 History or evolution of the Directory 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 of 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 9/13/2018 5

Directory 11 History or evolution of the Directory Directory 11 • 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) 9/13/2018 6

Directory 11 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 9/13/2018 7

Directory 11 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 overvoltage, 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. 9/13/2018 8

Directory 11 Key differences from PRC-002 – Recording lengths • PRC-002 – Pre-trigger 2 cycles and minimum total record 30 cycles or 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 9/13/2018 9
