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

25

GIS Data Quality Issues Plague Other Utilities

GIS Interest Group

Mitigating Data Quality Issues

26

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
