1 Spatial Representation and Analysis of Distribution Outage Information

2 Distribution Geographic Information System (DistGIS) Maintains Distribution Model Generates Map Products Provides Model to Other Engineering Applications at Gulf Power

3 Trouble Call Management System (TCMS) Imports Distribution Feeders from DistGIS Handles Trouble Calls Records Detailed Trouble Information

4 DistGIS/TCMS Interface Distribution Feeders Extracted Daily to TCMS The Outage Tool creates a new TCMS to DistGIS Interface. Display Outage Points Create Outage Maps

5 Tool Placement Reliability Engineers Limited GIS skills Not terribly interested in learning GIS skills Companion to traditional tabular reports, not a replacement Reports Identify Feeders of Interest Maps Provide Better Analysis

6 Map Example Single Page Feeder Map Whole Feeder on 1 Page Intended for Online Review and Markup 3 Outage Layers Events Devices Customers Attributes Excel Spreadsheet

7 Event Outages Legend

8 Device Outages Legend

9 Customer Outages Legend

10 Symbology Large Symbols Easily Visible While Scanning Large Portion of Feeders Draw Order Events Devices Customers Feeder Draw Event, Device, Customers at decreasing sizes so all show up

11 Reliability Improvement Initiatives Worst Performing Feeders Most Customer Outages Recurring Trouble Animal Mitigation Lightning Mitigation

12 Worst Performing Feeders Improve SAIDI on Worst Feeders Across Company Outage Studies Performed Over Previous Year Steps for Reliability Engineers Compile list of top 10 worst feeders by SAIDI Generate Worst Performing Feeder Maps and Reports Strategic patrol of feeder for mitigation opportunities Generate work orders to repair

13 Most Customer Outages Reduce Outages for Customers having the Most Outages Analyze Most Customer Outages across the company Outage Studies Performed Over Previous Year Generate Most Customer Outages Maps and Reports Generate Worst Performing Feeder Isolating SAIDI5 Customers Maps and Reports

14 Recurring Trouble Correct Problems that Cause Multiple Device Outages Analyze Most Troublesome Devices Across the Company Outage Studies Performed Over Previous Year Generate Worst Performing Devices Maps and Reports Isolate Particular Types of Outages

15 Animal Mitigation Reduce Total Number of Animal Outages Animals Are #1 Cause of Total Outages Outage Studies Performed Over Previous 3 Years Steps for Reliability Engineers Compile list of top 10 feeders of animal outages Generate animal outage maps and reports Strategic patrol of feeder for animal mitigation opportunities Generate work orders to repair

16 Lightning Mitigation Reduce Total SAIDI from Lightning Lightning is #1 Cause of SAIDI Lightning studies are performed over previous 3 years Steps for Reliability Engineers Compile list of top 10 feeders of lightning outages Generate lightning outage maps and reports Strategic patrol of feeder for lightning arrestor opportunities Generate work orders to repair

17 Data Collection Event Table 1 Row per Outage Event Unique Event Code Event Location Number Date Feeder ID Cause DTR Flag Customer Table 1 Row per Customer Out Event Code Customer Location Number Feeding Transformer Location Number

18 Data Quality Historical Information on Current State of Circuit Device Changes Cutovers Customers Come and Go Location Numbers provide permanent unique identifier Equipment Number, XY coordinates Change Over Time Data Capture Quality No Free Text Input Field Personnel Understand How Data is Used
