  1. Enoch DaviesAssociate Engineer Base Case Basics

  2. “People who work together will win, whether it be against complex football defenses, or the problems of modern society.” Vince Lombardie “If everyone is moving forward together, then success takes care of itself.” Henry Ford

  3. Introductions From the WECC Staff • Doug Tucker • dtucker@wecc.biz • Enoch Davies • enoch@wecc.biz • Kent Bolton • kent@wecc.biz

  4. Discussion Outline • WECC Base Case Building Procedure • Reporting Data Anomalies

  5. Base Case Building Power flow • From each AC we should receive the following: • Area Specific power flow data • L&R spreadsheet • Any dynamic model changes/updates • Any tie line changes (must be coordinated!!!) • List of significant changes • Any additional info that will help with base case compilation

  6. Creating a Raw Case

  7. The Master Tie Line File Contains raw data for the following: • Branches • Transformers • Line connected shunts • DC lines (Bus, Line, DCC) • Transformer impedance tables • Interface data (Paths) • Branch interface data • Zones • Owners • Area Interchange

  8. Tying It All Together

  9. Area Interchange Schedules BC Hydro Interchange with Northwest 2300 MW Northwest Interchange with BC Hydro -2300 MW

  10. Power Flow Solution and Data Checking • Island check • Tie line check • Edit table checks • Mustfix.p • Checks.p • svdsnap.p • Overload check (Line & Path) • Solution check • Baseload flag check

  11. Questions About Power Flow Compilation?

  12. Base Case Building - Dynamics • The Master Dynamics File (MDF) • Models • Updates in PSLF format • Temporary vs. permanent changes • Motor load modeling • Condenser and pump check • Unused models

  13. Initializing Dynamics Data • Reading in the MDF • Missing data • Duplicate models • Modstat.p • Built into PSLF 17.0 • Initialization • Governor errors/warnings • Exciter errors

  14. Running and Plotting • A no-disturbance run • The alldyns.p disturbance routine • Ringdown • Double Palo Verde Outage • Loss of PDCI • Plotting the channel file • Searching for the largest deviation (spread) • Plotting parameters

  15. Base Case Building - Comments • Types • Submitted in EPCL, EPC, .m, or by list • MUST be made to review case • Changes to tie lines must be coordinated • Extensive data changes

  16. Questions about Dynamics and Comment Submission?

  17. Reporting Data Anomalies • Master Tie Line File Data • Series Compensation • New Phase Shifters • Additional Solution Tools • Any Area Substitution Data • PSS Exemptions • Dynamics Data • Study Report Suggestions
