Our “Fuel”

Jump to first page Reporting Requirements n CFR 40 part 60 n State Title V permit n NOX, SO2, CO, opacity u O2 u Steam n At least two “good” 15 minute averages required to create an hourly average

Jump to first page Inops and Exceedances n Inop Is a Loss of Valid Data Due to a Monitoring Equipment Problem n Exceedance Is the Violation of Permitted Concentration, Opacity, or Emission Rate n Each Inop or Exceedance Must Be Recorded and Assigned a Reason and Action

Jump to first page Reporting Requirements n Monthly,Quarterly, Semi-annual and Annual Reports n Quarterly EDR – Electronic Data Record u Comma Separated Values u Very Precise and Specific Format u Documents RATAs, CGAs, Exceedances and Inops

Jump to first page Project Execution n Searched, Interviewed and Selected PI System Integrator. n Installed VPN Capability. n Used Simulators at Start. n Ten Days of Meetings With Integrator. n Were Able to Run New System in Parallel With Old.

Jump to first page Summary n A Complex System That Came Together Smoothly u Open Architecture. u Standard, Configurable Tools. n We Have All the Application Code Available to Us. n PI Has Proven to Be an Ideal Platform

Jump to first page Things to Keep in Mind….. n PI Server n Averaging n Time Stamping n Data Types n Tag Naming n Tracing n Recalc n Overrides

Jump to first page n Use a dedicated PI server if possible. u Avoids interference from other plant activities. u Data custody. u Data retention. n Averaging – u Can’t just average raw values. u Each value needs to be validated. u Store results without compression.

Jump to first page n Time stamping – typically at beginning of time period. n Data types – u use full precision for manual input values and calculations. u Use integers to hold “state” data n Tag naming – use structured tag names.

Jump to first page n Tracing – aids in development, testing and auditing. n Recalculation – allows Manual Inputs to be re-processed, BAF’s to be reapplied, logic errors to be corrected. n Overrides – provide ability to correct for operations or maintenance errors.
