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

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

AMS Communication Networks

RF Mesh Network900 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

ITSystems

In-Home Display Smart Appliances

Home Area Network

Integration with OMSFuture

• 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
