2MSRATF EngagementMSRATF formed in August by TSS upon assignment from PCC Chair – Responsive to Sep 8, 2011 event(Perform contingency events in WECC cases across the system with a few mouse clicks)Details in Needs Statement, Scope Statement approved by PCCIncludes vendor participation by GE, Siemens/PTI, PowerWorld, V&R, and PowerTechWECC groups helping include TSS, RPSOTF, MVWG, SRWG, RASRS, Relay WGWECC web site for documents:WECC > Committees > Standing Committees > PCC > TSS > Documents > MSRATF Documents
3MSRATF MeetingsSince August 2012, 6 face-to-face meetings and many WebEx sessionsFormed three subgroups with vendor representation in each groupRASRelays (Modeling Sequence Component Networks)Contingency Definitions (Breaker Node Topology)AdditionalBreaker Node TopologyModeling Sequence Component Networks
4RAS Subgroup James O’Brien (BPA) Developing a Generic RAS specificationMSRATF approved on Tuesday 8/7Seeking MVWG comment and approvalWith WebEx (8/26 at 2:00 Mt time)Seeking TSS comment and approvalWith WebEx (9/5 at 2:00 Mt time)Donald Davies will be ing to you this week.
5RAS Subgroup James O’Brien Colstrip owners are developing an ATR specificationPAC is beginning to develop a Bridger RAS specificationJason Wilson presented an overview of the Bridger RAS5
6RAS Subgroup James O’Brien To demonstrate responsiveness to 9/2011 Outage Report recommendations we are asked to post and share Conditional RAS model files we currently use:Send RAS files to Enoch by 8/21 to postUnder 2013 Base Cases, folder at bottom of web page: Contingency and Remedial Action Scheme Files (Various Formats)Template for RAS descriptions also being developed for later, starting with WAPS
7Relays Subgroup Amos Ang (SCE) Amos is new chair, taking over for Tracy3Φ Over-Current, non-directional RelaysMVWG approved existing relay models for WECCMSRATF & MVWG approved spec for 3Φ, non-directional, curves and equations Over-Current relay (use for RAS)Power Flow (steady-state) & Transient Stability (instantaneous and inverse time)Seeking TSS approval, then vendors will develop and jointly validate with WECC
8Relays Subgroup Amos Ang TSS Motion: Approve generic specification for 3Φ, non-directional, curves and equations Over-Current relay!!Next – Generic 3Φ Distance relayAfter that – 3Φ, differential relaysSoon - 3Φ, directional component to overcurrent relayThen – Model unbalanced sequence networks in WECC planning casesAnd – 1Φ Directional Over-Current and Distance relays
9Contingency Definitions Subgroup Jonathan Young (CG) Developed a Contingency Definitions generic specificationContingency file will be common format, read (translated) by all programsEditing, sorting, selecting would be done within the programsSeeking TSS approval, then vendors will develop and jointly validate with WECC
10Contingency Definitions Subgroup Jonathan Young TSS Motion: Approve generic specification for Contingency Definitions!!Developing specification to import / export in Contingency Definitions in BCCSBeginning to develop Breaker-Node Topology for WECC planning casesExplore changes to contingency definitions and relay models (bus / branch)
