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 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 –  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 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 DisplaySmart Appliances Home Area Network

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
