GIS: Source of Record for OMS’s 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.

But Data Quality Issues Can’t 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 OMS’s greater dependence on GIS data quality
– Insuring GIS data is updated when field changes are made
– Personal accountability for GIS data quality

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

EPRI’s 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)

Information Sharing = Better Outage ManagementOncor is striving for better two-way customer communication
