GIS to Schematics - The Data Exchange
2 likes733 views
The document details a presentation on the integration of GIS with schematics by Pacific Gas and Electric Company (PG&E), highlighting key project managers and their extensive experience. It outlines the infrastructure of PG&E's GIS systems, the functionality of the ESRI schematics product, and the objectives for converting existing GIS data into updated schematic diagrams. Additionally, it emphasizes the collaborative efforts and support from multiple teams that facilitated the successful conversion of over 4,200 diagrams and timely updates to schematics based on GIS changes.

GIS to Schematics - The Data Exchange
- 1. GIS To Schematics Esri GeoConX White Paper Presentation October 19, 2016
- 2. PRESENTERS Peter Zimmermann • UDC Inc. • Sr. Project Manager – GIS data • Over 25 years gas and electric utility project management experience • Working with PG&E for over 3 years • Project Manager for Schematics project Robert Smith • Pacific Gas and Electric • Electric Distribution Lead -‐ Business Operations Support • Over 31 years with PG&E • GIS Implemented 2013 • PG&E business requirements lead -‐ Schematics project
- 3. PG&E – WHO WE ARE ü Pacific Gas and Electric Company was incorporated in California in 1905 ü There are approximately 20,000 employees who carry out Pacific Gas and Electric Company's primary business—the transmission and delivery of energy ü The company provides natural gas and electric service to approximately 15 million people throughout a 70,000-‐square-‐mile service area in northern and central California. ü Pacific Gas and Electric Company and other utilities in the state are regulated by the California Public Utilities Commission, created by the state Legislature in 1911.
- 4. PG&E – SERVICE TERRITORY • Service area stretches from Eureka in the north to Bakersfield in the south • 2.4 Million Wood Poles • More than 141,215 circuit miles of electric lines (over 120,000 of Overhead) • More than 42,141 miles of natural gas pipelines. • 5.3 million electric & 4.3 million gas customer accounts.
- 5. BACKGROUND INFO PG&E GIS Infrastructure • ArcGISArcFM Desktop 10.2.1 – 5 Citrix Servers • ArcGIS Server/ArcFM Server 10.2.1 – 7 servers -‐ 84 cpus • Oracle RDBMS – 2 node RAC • ArcGIS Desktop Schematics – 4 Citrix servers • SAP Enterprise Asset Management • IVARA Inspection & Maintenance Management • ArcFM CM/UFM • Ventyx Network Manager OMS • Ventyx Field Service MWM • CYMEDist Distribution Planning System • Oracle CC&B CIS • Documentum Content Management System • AutoCAD Estimating, Design, Drafting • Transformer Load Management (TLM) • Distributed Energy Resource Management (ENOS) • Engineering Settings • Feeder Device Information / Fault Duty, I-‐ BAL (FDI) • SAP BO Data Warehouse
- 6. WHAT IS THE SCHEMATICS PRODUCT • Esri extension that works with ArcGIS/ArcFM • For PG&E it provides primary circuit system representation • Easy to read; quick reference for primary equipment • Graphic Data is housed as diagrams in a standalone database • Annotation is kept with the GIS feature as an added anno class • Also applicable to gas systems
- 7. GIS AND SCHEMATICS VIEW
- 8. BUSINESS CASE FOR SCHEMATICS • Replace current Cadd based circuit maps • Integrate with GIS to make schematics closer to real time • Help support switching in the OMS system • Ability to plot as needed
- 9. SCHEMATIC DESIGN OBJECTIVES • Try to stay with a COTS solution as much possible • Create symbology familiar to current users • Colorize conductor features by circuit number • Provide a product that can be distributed using the internet (Web Viewer) • Keep up to date using the GIS editing process • Keep it easy to maintain the generated schematics • Keep features relative to the major land features (geo-‐schematic)
- 10. CONVERSION TASKS • Convert existing GIS data into Schematics diagrams using schematic engine, and model rule definitions • Adjust graphics and annotation for over 4,200 -‐ 500 scale and 100 -‐ 50 scale diagrams using predefined specifications and schematic edit tools • Adjust graphics to create a geo schematic • Edgematch at all diagram boundaries • Ensure all annotation is associated to the correct features and perform general white space management
- 12. CONVERSION BEFORE • Generated by the Schematics processing tool
- 13. CONVERSION AFTER • Edit using Schematics editing tools • Tech uses GIS view to help with schematic placements
- 14. CHALLENGES • Convert and clean–up 4,200 diagrams on an aggressive schedule • Managing the GIS based annotation during the conversion process • Provide a consistent looking product across all regions • All diagrams were edgematched • Address dense areas (UG) and maintain general geo positioning • 50 scale diagrams • “Blow up” tight areas • Come up with a strategy to deal with extremely dense areas such as San Francisco (Multi-‐view)
- 15. MULTI-VIEW SOLUTION (OMS) • Separate views for Radial, Tie and Network Conductors • Users are able to toggle between views on the fly RADIAL TIE NETWORK
- 16. MAINTAINING THE SCHEMATIC DATA CHALLENGES • Only capture GIS changes that affect schematics features model (Change detection tools) • Create a repository so no Schematic edit is missed (Geo processing tools) • Create an Schematic editing environment (Check-‐out/Check in tools) • Keep current with GIS
- 17. MAINTAINING THE SCHEMATIC DATA
- 18. MAINTAINING THE SCHEMATIC DATA SUP – Schematic Update Polygon Features that were edited in GIS (shows the positioning in the GIS) SIP – Schematic Interactive Polygon Area to be cleaned up in Schematics diagram(s) SUPS AND SIPS
- 23. ACCOMPLISHMENTS • Over 4,200 diagrams converted and cleaned by UDC • Successful publication to PG&E Webviewer • Implemented schematic view within the DMS application (OMS) • Schematic updates within 48 hours of GIS change • Over 30,000 SUPs processed annually by UDC
- 24. WHAT MADE THIS POSSIBLE • Substantial and continued support from PG&E stakeholders and management • Close coordination between multiple teams at PG&E, ESRI, UDC and IBM • Critical design input from many PG&E departments • Solid project management provided by all parties during conversion and SUP maintenance
