Business Challenges and Opportunities

• Connectivity Model
• No connectivity model available, only one-line
  diagrams in AutoCAD
• No Transmission connectivity tool available to
  analyze SCADA data and outage data
• Multiple copies of transmission line database
  throughout company
• No real-time weather data or warning reports over
  our assets
• Area load by state and company needs updates
• No area load available for operating areas
• No standard tag naming convention for most PI
  tags
• Transmission reliability statistic calculation
  done in Excel
• Alive T.V news for operation dispatchers
• Calculation on Weather Data
• Manual download from weather underground and NOAA
• Manual weather calculation, weather variables,
  and load correlations

Business Solution

• PI Archived Data-ACE
• Developed VB.Net application to access free NOAA
  weather data and archive in PI server.
• Create calculation tags CDD, HDD, daily average
  Temp, daily peak Temp, etc.
• Total area load calculation by operating area,
  state, and by operating companies.
• Connectivity Model
• Real-time SCADA data over PAC transmission
  model-Process Book
• Merged multiple transmission line databases into
  one.
• Link to relational database to add non-SCADA data
  over model.
• PI tags are mapped to each appropriate asset.
• Convert AutoCAD drawing to display in Process
  Book.
• Real-time warning and reports over transmission
  model-Google Earth Pro
• Existing ESRI GIS shape files was converted to
  Google Earth KMZ files.
• Free Java Script to convert asset connectivity
  data to KML file.
• Free web services for lightning, weather, fire,
  warnings, etc.
• Reliability Statistic tool.
• User resources
• Department MS Sharepoint site to provide platform
  for training videos, users manual, document
  library, WIKI, and technical support.

Business Values

• Quality Data Analysis
• Aggregation of loading data that is consistent
  with area planning facilities
• Engineers and planners now can normalize weather
  variation into load history analysis and load
  forecasts
• Simplified assembly of transmission line
  performance for benchmarking and outage
  calculations
• Easy verification of outage time stamps and
  unknown causes.
• Updated PI total load information
• Transmission reliability performance
• Utilization of resource and time.
• Easy to identify PacifiCorp topology and asset
  location
• No need to go back to schematic (one-line
  diagram) drawings
• One master database for transmission line ratings
• No calls to PI administrator to translate tag
  names
• WIKI site for technical support and trainings
• Quality real-time monitoring for operation
  dispatcher
• Visual topology presents simplified status of
  transmission facilities
• From T.V news to real-time weather reports and
  warnings over Google Earth model, as well as
  fire, lightning, earthquake, etc.
• Real-time PI data over transmission model

Considerations

• What was available
• PI with ACE (Advance Calculation Engine)
• ESRI GIS files
• Visual Studio 2005
• PI Process Book
• Web services
• Visit to book stores
• What we bought
• Google Earth Pro
• What we are researching
• Archive-quality lightning data into database
