1. SWEDE 2011 Conference Design-Smart Grid Workshop Presented by
Frank Daniel
Oncor Electric Delivery

2. Deployment Remote Control (600) and S&C IntelliTeam II (650)
Approximately 1250 switches Total
Switch types
ScadaMate
ScadaMate cx
Intellirupter
PMH
Vista

3. Deployment Previous installations 100-250 per year
Present installations approximately 30
CREZ
Typical cost - $75,000 per switch including repeaters
Normal installation is 1.5 switches per feeder

4. Deployment Capacitor controls Remotely monitored Fault Indicators 3600
SEL FCI – 6
Cooper - 3

5. Deployment Organizational responsibilities
Engineering
DOTs in field handle simple task
PNC techs out of WDOC handle all other aspects
After CREZ will pick back up to around 250 units per year

6. Switch Specifications
Interrupting Ratings – 12.5 kA
Voltage Ratings – 12.5 – 35 kV
Continuous Current rating – 630 amps
800 amps for short periods
Reclose Provisions – IntelliRupter only
Communications
L&G
S&C SpeedNet
Fiber

7. Mounting/Installation Requirements
Pole mounted switches
ScadaMate – Class 5 wood pole
IntelliRupters - Class 3 wood pole
Padmounted switches only in selected applications
Install at highest elevations possible
East Texas taller poles for better communications

8. Maintenance Provisions
By-Pass switch – standard recloser type with isolation and by-pass
IntelliRupters offer best modular approach
Programming done in advance
Install switch and some simple commissioning
Testing
S&C software for programming and trouble shooting – no in-house software

9. Safety Requirements Working line hot Working Line dead
Set hot line tag
Working Line dead
Visible Open required
Ground line section
Substation Integration Module (SIM)
SIM provides load information to switches
SIM takes switches out of ready for manual breaker operation, under frequency, etc

10. Non-AMI Communications
Communications in general is a mesh network with peer to peer communications
Back haul is cellular modems
Some sellected sites have fiber communications
All switches have local control / monitoring
Face plate – 5800 controls
Laptop via WiFi - IntelliRupter

11. Non-AMI Communications
Collecting Data
Manual
Initiated for trouble shooting and reports
Data includes
Loads
Switch operations
Automatic operations
Status of switch
S&C software is used to connect to switches

12. Advanced Metering Initiative
More than 1.5M total meters installed through December 2010
Industry-first, customer information portal launched in 2010 –
Began In-Home Monitor pilot program to 500 customers
Cooperating with Texas Retail Electric Providers by interoperability testing HAN devices for their rollouts

13. AMS Communication Networks
RF Mesh Network
900 MHz
Collectors
Mounted on 70 ft. concrete poles
Four antennas on the top, and a control panel and backhaul communication box at the base
Normally located in substations, within substation fence
Approximately 250
Backhaul Network
Satellite, microwave, cellular, fiber, and wide area network
Repeaters/Routers
Mounted on utility poles and street lights
Approximately 36 per collector
Approximately 9,000
Back Office
Advanced Meters
Installed in residential and commercial premises
Meter-to-meter communication
Approximately 378 per repeater/router
Approximately 3.4 million
IT Systems
In-Home Display
Smart Appliances
Home Area Network
AMI Integration
Evaluating two-way capacitor controls and FCIs
AMI communications layered
Takeout point
Routing
Meter (quazi routing)
Problems
Separate takeout point required
Command Center for DA
DA communications has priority over metering

14. Integration with OMS Future
Meters to provide last Gasp after outage
Transformer
Fused lateral
Switching device
Switches will provide sectionalization for faults
Switches and meters will provide load and voltage information
Planning will use info from switches to verify loads

15. Budgeting / Cost Recovery
Cost recovery at present is imbedded in rates
Budgeting is based on available funds and formula applied to each request
All installations have a separate code for tracking purposes

16. Oncor Substation Architecture – VLAN & VRF Tunnels
Virtual Routers
Securely ties Tunnels to VLANs
