What is pc-GAR?


                         Unique software product
                          to allow access to the
                          data collected in the
                          GADS database.
                         It reports equipment
                          outage information for the
                          purpose of improving
                          electric power output.



             pc-G.A.R
Why pc-GAR?

  Introduced in 1992
  Created to:
   • Reduce the number of special studies produced
     annually.
   • Allow users quick access to GADS information.
   • Increase the need to maintain good outage records.
  Only one of it’s kind in the world!
   • WEC wants to follow this example
With data mining, you take advantage
        of past experience …
     you learn from the past to
       prepare for the future.
Unit Types Available (12 choices)


  Fossil                  Hydro
  Fluidized bed fossil    Pumped Storage
  Nuclear                 Combined Cycle

Help with pc-GAR
Help #1 – Selecting Fuels

  Two fuel selections
    • “As designed” means what the unit was designed to
      burn.
    • “Actual fuel burned” means what did the unit actually
      burn in the specific year.

  100% of the “actual burned” fuels
  90% of the “designed fuels”
Help #1 – Selecting Fuels




     Actual Fuel Burned     Design Fuel
Help #2 – Apply Criteria By…

  You can apply the performance/fuel criteria by
   either year or range.
    • Year – tests the criteria on a year by year basis. A unit
      may pass the test one year but not the next. Only the
      one year where it passed will be in the survey.
    • Range – tests the criteria on the average for the
      period you selected. If you picked a 5-year period for
      an EAF > 85%, then the average EAF for the period is
      tested. If it fails, that unit will be removed from the
      survey.
Help #2 – Apply Criteria By…

 Accepted     EAF = 90.40%
                               If criteria included
 Accepted     EAF = 87.56%     EAF of 85% or
 Rejected     EAF = 84.55%
                               greater, then 3 of
                               4 years accepted using
 Accepted     EAF = 85.98%     “Year” button.


                               If criteria included
                               EAF of 85% or
 Accepted     EAF = 86.91%     greater, then average EAF
                               of 4 years accepted using
                               “Range” button.
Help #3 – for Years/for Periods

  Events and performance data are divided into monthly
   intervals for retrieving and analyzing data by months, years,
   and multi-year periods.
  When using less than one year, use:
    • “Annual/monthly Unit Summary Report” for viewing
      monthly numbers.
    • “Unit-year Statistical Report” for projections of how the
      unit would operate if operated in the same manner as
      the short period.

Help #4 – Adding/removing Units

  pc-GAR allows you to add or remove youp own
   units from any selected group (“units included in
   report”)
  You cannot remove units that NERC considers
   not yours (even if you are a part-owner.)
   “Ownership” (to NERC) is the organization
   reporting data to GADS.
Help #4 – Adding/removing Units



                                   All own units

                                  and out of the report.
Help #5 – Same Peer Group

  This procedure allows you to use the same group of units
   from one period to the next, assuming the same units
   reported in both periods.
  First, select the group of units using the standard
   procedure for choosing a group.
  Second, in “Menu of Reports,” choose “Report Data
   Range.”
  Third, select a new period to analyze.

                            group of units.
Help #6 – Single, Own Unit Report

  For when you want to create a pc-GAR report for
   just one of your own units.
  Normal selection procedure for own units.
  Remove all but the single unit from the “Units included
   in Report” section.
  Apply criteria as “Reapply Criteria …”

                                    you normally do.
Help #7 – Data Making Statistics

  There are three options for choosing the units
   and data for making the statistics in the reports:
    • Units that report both event & performance records
      and units reporting performance data only.
    • Units that report both event and performance data
      only.
    • Units that report both event and performance data for
      all years of the period.
Help #7 – Data Making Statistics




    This option includes all units reporting to GADS, whether
    they reported events data or not.

    This option may show differences in statistics like EAF, EFOR,
    EFORd, etc because not all units reported deratings.
Help #7 – Data Making Statistics




    This option includes all units reporting to GADS where
    events are reported during the period being examined.

    This option will show accurate statistics like EAF, EFOR, EFORd, etc
    because all units report deratings.
Help #7 – Data Making Statistics




    This option includes all units reporting to GADS where events were
    reported during the complete period being examined. If you were
    examining 5 years, the unit would have to report events all 5 years.

    This option will show accurate statistics like EAF, EFOR, EFORd, etc.
    because all units reported deratings.
Help #8 – Start Fresh or Re-examine?


  When retrieving data, you have the option to
   start fresh each time or re-examine the existing
   data.
  It is faster to start with a big group, add a criteria,
   and then re-examine the group as each criteria
   is added.
Help #8 – Start Fresh or Re-examine?




   Always uses this option when starting a new retrieval or increasing the
   population of an existing retrieval.
Help #8 – Start Fresh or Re-examine?




  Use this option if you are “trimming” an existing retrieval. Never use it if you
  suspect that the population of the retrieval will increase.
Help #9 – Inclusion

  In pc-GAR, the software assume you want
   everything unless you specify that you only want
   something special.
  For example, the program will assume you want
   all NERC Regions unless you specify you only
   want two certain Regions.
Help #10 – Exclusion

  In pc-GAR, you may have to specify you DON’T
   WANT something in order to get the condition
   you really want.
  For example, if you wanted units with a single
   reheater in the boiler, you would have to specify
   that the first RH section is 1 to 9999 psig and the
   second RH section is 0 to 0 psig.
Help #10 – Exclusion




          By placing a “0” (zero) in some criteria, you can
          focus on special cases of design. Here we locate
          single RH units and remove non- and double RH.

Question & Answer
What is pc-GAR MT?
What is pc-GAR MT?

  Software product to provide a distribution of
   times to repair (TTR) and times between failures
   (TBF)
  Software product to provide Mean TTR and
   Mean TBF for modeling and analysis programs
  Software product that allows YOU control of the
   units in the data set.
Events as Reported to GADS

  Most events are shown as one, continuous
   activity per year
  However, there are some where the single event
   is divided into parts by:
   • Months for internal utility reporting
   • Years as part of the GADS cut off
Need for New Software

  Combine monthly events into one
  Combine year-ending & year starting events into
   one
  Ability to isolate events by event types
  Ability to isolate events by cause codes or
   groups of cause codes
