Design of process supervisory system for thermal power plant based on systems engineering

The design and application of the production process supervisory system for the thermal power plant were emphatically demonstrated in detail. The systems engineering methodology was applied during the whole design process. From the actual process situation and the systematic overall function, the correct scheme decision had been made by the analytic hierarchy process (AHP). Then all the pictures of the supervisory system were programmed and made. According to about three-year successful application in a certain power plant, it is demonstrated that this supervisory system has many characteristics of high reliability, perfect functions, convenient operation and use, low cost and flexible configuration etc. Its application not only provides help for operators, but also improves the managing level of the production. Thus the production in the thermal power plant is safe and stable.
