Automation History

CenterPoint Energy (CNP) has had automation in place
for over 40 years




1970’s - Substation relays - SCADA
1980’s - Remote Control Reclosers & Pole Top Switches Distribution Automated Control System (DACS)
1990’s - Loop Sectionalizing - DACS
2010 – Department of Energy/CNP IG construction project begins
 2010 - 18 IGSDs installed
 2011 - 183 IGSDs installed; year end = 201
 2012 - 183 IGSDs installed; year end = 384
 DACS converted to Distribution Supervisory Control and Data
Acquisition (DSCADA)
 2013 - 21 IGSDs installed to date, 4/11/2013
Legacy DACS Maintenance Program

Legacy DACS Maintenance Improvements
DSCADA equipment monitored by Telecommunication & Control
Systems Orgs
 SAP Notifications
 Intelligent Distribution Device (IDD) work orders dispatched via
Mobile Data
 Distribution techs are DSCADA first responders
 System oversight and 30 day restoration metric




≈ 31 Substation
Upgrades
≈ 180 Distribution
Circuits
≈ 600 Intelligent
Grid Switching
Devices (IGSD)
≈ 420K Customers
Construction
Schedule

5,000 Square Miles
2.3M Customers
16.4 GW Peak
14-19 installations
per week
 67% Complete YE
2012
 100% by YE 2013
Challenges and Opportunities

New Technology





Multiple Vendors (5 IGSD combinations)
Failures & Material Issues



Firmware
Dual communication requirements
Distribution SCADA (DSCADA)
Volume of installations demanded higher expectations
Documentation of issues into a multi-departmental log
Training

Distribution Operations techs required training on new installations
and maintenance of devices
QA/QC Vendors

Vendor Audits


Audit Reports


Factory visits
CNP provided feedback
 Good/Best practices
 Gaps and improvement recommendations
Issue Resolution



Return Material Authorization (RMA) Reports
CNP encourages transparency with ALL issues
Encourage synergy between CNP and Vendors during acceptance
and installation
QA/QC CNP

Logistics


New Pallet design (Facilitates Testing and Shipping)
Shops




Itemized checklist (Tester’s signature)
Hi-Pot, Current Injection, and Relay Testing
Communication & DSCADA Testing
Kit (Distribution material palletized with IGSD)
QA/QC CNP (Cont.)

Field Installation and Commissioning




DPD crew and Telecom tech onsite
DPD crew and Distribution Controller partner to commission IGSD
 IGSD Commissioning Document
QC Each site is independently inspected
 IGSD QC report
Issue Log & Documentation


All issues are documented into a central issue log
Risk Management provides oversight
IGSD Test Farm
IGSD Test Farm
Availability Report 4-11-13
Operational Opportunities

Improved System Reliability


Critical Infrastructure is only out of service for short periods of time
 Existing Manual Switch replaced by IGSD within 2 days
 Existing IGSDs are out of service less than 14 days
Efficiencies Gained




IGSDs are fully tested prior to installation
 IGSDs are communicating upon construction completion (87%)
Kits require less hot shot deliveries
Early issue/problem detection
Defined, Repeatable, and Scalable Processes
