Design of distributed control system for Malakoff Generating Station

Microprocessor-based distributed control technology can provide increased reliability and flexibility, and together with an integrated operator interface promises better plant efficiency and availability. An overview of the procedure followed in engineering a distributed digital control system with an integrated operator interface for a large lignite-fired generating plant is presented. The system includes Boiler and Burner control, Interposing Logic System and the Plant Monitoring Computer. Design criteria, vendor selection and overall system architecture for the chosen equipment are described. System limitations and problems encountered to date are addressed.
