    • Case Study Utilizing AMR Functionality and the OMS Detailed Circuit Model Gregory A. Wolven, P.E. Director of Engineering WIN Energy REMC
    • In the past, all of us have lived with our software processes because…. “We have always done it this way.”
    • Topics to Cover • Who is WIN Energy REMC? (put things in perspective) • AMR and AMI • Engineering and Operations Benefits • AMI Tools (Grid Stream™ or Smart Grid) – Outage Management – Load Studies – Power Quality
    • Who is WIN Energy REMC?
    • • • • • Located in SW Indiana Approx. 16,500 meters 135 MW NCP 40 Substations – 17 Dedicated – 23 Residential • Approx. 1,500 sq. mile Territory • 46 total employees
    • Topics to Cover • AMR and AMI – AMR – Automated Meter Reading • Typically just for meter reading, typically a one-way information flow FROM the meter to the processing software. – AMI – Automated Meter Information • Much more powerful system than AMR; takes the information provided by AMR and adds additional functionality such as request / response regarding outages.
    • Topics to Cover Engineering and Operations Benefits  Engineering and Operations benefits greatly enhance the AMI business case. – These benefits include, but are not limited to the following: • Blink Count – Use this option, along with a good OMS system, to help track down system disturbances and, therefore, enhance member service satisfaction.
    • Topics to Cover Engineering and Operations Benefits  Engineering and Operations benefits greatly enhance the AMI business case. – These benefits include, but are not limited to: • Signal strength from each meter (or endpoint) – This can be used to enhance AMR performance. – Continuously look into potential problems, proactively meter, circuit and substation BEFORE outage events occur. » Vines, tree contact, bad connections
    • Topics to Cover Engineering and Operations Benefits, continued • kW Demand – Transformer sizing – Load Flow » Enhanced with a good EA system, system planning is taken to a level few dreamed of even as recently as 5-10 years ago.
    • Topics to Cover Engineering and Operations Benefits (cont.) • System Line Losses – Aggregate System losses mask issues (or opportunities). – The ability to use daily energy readings allows both cycle billing and the ability to read ALL meters at the time of supplier billing. – The ability to review losses by delivery point allows focused review of places opportunities for efficiency improvement exist. » Example: 2008 “unaccounted for” kWh = 28,064,840, which was a SYSTEM line loss of 4.62%. This represented a direct increase in the purchased power of $1,643,472. MOST of WIN Energy REMC’s substation line losses were around 10%. Dedicated substations (zero line loss) masked the real issue.
    • AMI and OMS Tools • Outage Management – Manage expectations. • AMR outage DETECTION (NOT outage verification) is a tool, not the “silver bullet.” – Realize system potential. – OMS integration and custom application • By graphically DISPLAYING meters that are in the lost status in OMS, outage detection and the extent of outages can be determined before visually verified, allowing better utilization of resources.
    • AMI and OMS • Realizing system potential – Looking for reoccurring problems
    • AMI and OMS – OMS integration and custom application • By graphically DISPLAYING meters that are in the lost status in OMS, outage detection and the extent of outages can be determined before visually verified, allowing better utilization of resources.
    • Managing Load • Managing Load – Reporting coincident data values that take guesswork out of load balancing and load flow – Improving line loss, sizing equipment, and distribution system design
    • Conclusion • Data Mining (AMR or AMI) – What has been discussed in this presentation is just the start. – Ask yourself “What is this data telling me?” – Results of daily unsolicited data from every meter can show trends and potential issues that users need to interpret for their system.
