3RASRS Scheme Reviews BC Hydro South Interior East RAS Consolidation of previously reviewed schemes for Kootenay Canal, Seven Mile, Waneta Expansion, Arrow Lakes Hydro, Brilliant Expansion, most of 5L91 and 5L96 RAS. No change to hardware, studies or arming, just reporting. Consolidation accepted by RASRS.South Interior East RAS modification for Waneta Expansion approved with one action itemModicon 984 PLC Replacements at Ingledow and Nicola were approvedNorth Vancouver Island RAS accepted as LAPSMica GS RAS upgrades and modifications approved with one action itemNatal previous action item resolution approved

6RASRS Scheme Reviews BPA RAS Test Intervals Proposed test interval changes for WAPS to target annual with a maximum of two years and for LAPS a target of 5 years with a maximum of 72 months (6 years). Accepted by RASRS.The following BPA scheme modifications were reviewed in closed session:West Side RAS controller and changes at Pearl and Keeler substations approvedJohn Day LLL (line loss logic) modifications were approvedGrizzley LLL modifications were approvedCaptain Jack LLL modifications were approved
7PRC-( )-WECC-CRT-2The revised criterion requires owners to track and report periodic assessments of schemes. This is a follow up to the September 8, 2011 disturbance.Effective date January 1, 2014
8WECC RAS Review Procedure Revision to the RAS criterion also necessitates some minor revisions to the WECC Procedure to Submit a RAS for AssessmentCriterion Attachment B dataPeriodic assessment review process explanationOC review/approval now!
9WECC RASRS Charter Significant Charter changes include: Removed a specific percentage of members present as a quorum requirementRemoved the Chair’s authorization to “approve” new RASRS members in favor of “accepting” nominations of new members from WECC member’s OC representativesOC review/approval now!
11WECC RAS DatabaseGood cooperation from WECC members for the annual database update in DecemberAESO “joined the party” with 39 schemesA few other (mostly) thermal emulation schemes addedMore removals than new schemes reviewed in 2013Presently 267 schemes in the database
12RAS & Protection System Oversight Task Force (RPSOTF) Task Force provides oversight of PCC/TSS MSRATF activitiesCo-chairs: Don Watkins, Dave AngellMembership drawn from:RAS Reliability SubcommitteeRelay Work GroupTechnical Studies SubcommitteeWECC and RC StaffTechnical Support, Standards, and others
13Modeling SPS & Relays Adhoc Task Force The MSRATF is organized under TSS (and PCC), Joe Seabrook, chair:RAS modeling groupRelay modeling groupContingency definition group
14Modeling SPS & Relays Adhoc Task Force “Big picture” objective is to develop and use contingency, relay, and RAS models as part of the Base Case Coordination System (BCCS), including models for unbalanced faults, accessed via a common data format from any of the four major software vendors’ programs.
15Modeling SPS & Relays Adhoc Task Force Specifications for Power Flow and Stability models already approved by MVWG:RAS modelsPhase Relays: Overcurrent, Directional, DistanceGround and OOS Relays: FutureNode-Breaker topology to be adopted
16Peak Reliability and RAS Peak Reliability (the RC) has been developing RAS models to include in their EMS models. RASRS is discussing database and collection coordination to minimize the number of separate data requests to WECC members and align both the RASRS data and the RC data to be collected.
17NERC SPS/RAS Standards NERC has a new drafting team to write a new SPS definition and related standards. Among the ten members are four from WECC:Gene Henneberg (NV Energy, Chair)Amos Ang (SCE)Davis Erwin (PG&E)Hari Singh (Excel)
18NERC SPS/RAS Standards There will be lots of chances for industry comment, but . . .Please provide any informal feedback to the drafting team, especially on the SPS/RAS definition, sooner rather than later.
19NERC SPS/RAS Definition Example SPS Exclusion: Schemes to protect against SSR, which might include:Local SSR filtersTorsional Stress RelayCritical contingency element monitoring and mitigation
