The design, development, and implementation of a data acquisition and handling system at Basin Electric Power Cooperative
- Black and Veatch, Kansas City, MO (United States)
The Clean Air Act Amendments of 1990 require all Phase 1 and 2 utilities to install Continuous Emissions Monitoring Systems (CEMS), which can consist of instrumentation including analyzers and a Data Acquisition and Handling System (DAHS). To meet these requirements, Basin Electric Power Cooperative contracted with Black and Veatch to design and develop a DAHS which would meet all 40 CFR Part 75 requirements. Basin Electric provided the specifications for the DAHS and the graphical user interface, and B and V designed, developed, and installed a DAHS at 3 units at Laramie River Station, 2 units at Antelope Valley Station, and 2 units at Leland Olds Station. B and V utilized the existing equipment, adding to it a unique DAHS design. B and V designed and implemented the DAHS which operates in the OS/2 environment to interface with multiple programmable logic controllers. This unique software was written in modular form so that multiple programs run in unison, monitoring each other for errors to ensure continuous operation. The reporting structure is flexible to allow for a variety of formats, including those specifically required by the state to meet CAAA guidelines. Today, these seven units are in operation and comply with the CAAA. This paper describes the issues faced during specification, general design, compliance, and implementation of the DAHS at BEPC, including the lessons learned. The continuous emissions monitoring (CEM) system for each unit at BEPC consisted of a set of dilution probe analyzers for measuring SO{sub 2}, NO{sub x}, and CO{sub 2}.
