20 GIS-to-OMS Interface Weekly DMS Storm Center Website

21 GIS: Source of Record for OMSs Electrical Connectivity

22 OMS: Uses a Weekly Extract of the GIS Connectivity Model

23 New GIS will Address GIS-to-OMS Interface Issues GIS & OMS will use identical connectivity models. GIS-to-OMS updates will be real-time & two-way. GIS will disallow user errors that adversely affect OMS.

24 But Data Quality Issues Cant Wait for the New GIS New OMS Requires New Focus on GIS Data Quality: Connectivity –Unconnected Features –Half Connected Protective Devices –Protective Devices with Duplicate Nodes –Self-Referencing Protective Devices –Voltage Changes –Closed Loop Errors Phasing –Transformer/Conductor Phase Mismatches –Inconsistent Phase Changes –Number of Phases Increase (when tracing out from the substation) New OMS Requires Process Improvements related to GIS Support Implementing tool to comprehensively measure fitness of GIS data Developing process to better track GIS/OMS data issues Updating GIS user training to focus on: –The new OMSs greater dependence on GIS data quality –Insuring GIS data is updated when field changes are made –Personal accountability for GIS data quality

25 GIS Data Quality Issues Plague Other Utilities GIS Interest Group Mitigating Data Quality Issues

26 EPRIs Goal: Quantify Benefits of Good GIS Data Reduced cost of deploying AMS network ($4.5-million) Reduced outage durations Reduced overall cost of operations –Reduced windshield time –Reduced O&M labor expenses Improved safety (due to more accurate connectivity) Improved load management (matching loads to transformers) Improved load forecasting and system planning Improved material management and forecasting Improved information exchange: –Internal (between departments and IT systems) –External (with governmental agencies and customers)

27 Information Sharing = Better Outage Management Oncor is striving for better two-way customer communication
