SWEDE 2011 Conference

Design-Smart Grid Workshop Presented by Frank Daniel Oncor Electric Delivery

Deployment

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

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

Deployment

• Capacitor controls – 3600 • Remotely monitored Fault Indicators – SEL FCI – 6 – Cooper - 3

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

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

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

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

Safety Requirements

• Working line hot – 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

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

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

Advanced Metering Initiative  More than 1.5M total meters installed through December 2010  Industry-first, customer information portal launched in 2010 – www.smartmetertexas.com

 Began In-Home Monitor pilot program to 500 customers  Cooperating with Texas Retail Electric Providers by interoperability testing HAN devices for their rollouts

AMS Communication Networks Home Area Network

AMI Integration

In-Home Display Smart Appliances

• Evaluating two-way capacitor controls and FCIs

RF Mesh Network

900 MHz • AMI communications layered

Backhaul Network

– Takeout point Satellite, microwave, cellular, fiber, and – Routing wide area network – Meter (quazi routing) • Problems   

Repeaters/Routers

Mounted on utility poles and street lights Approximately 36 per collector Approximately 9,000

Collectors

  Mounted on 70 ft. concrete poles Four antennas on the top, and a control panel and backhaul

Back Office

  – Command Center for DA Meter-to-meter communication  communication box at the base Normally located in substations,  within substation fence   Approximately 250 • DA communications has priority over metering

Advanced Meters IT Systems

Installed in residential and commercial premises Approximately 378 per repeater/router Approximately 3.4 million

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

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
