TPP Generating Unit Technical and Economic Index Accuracy Increase

Abstract

Calculation of technical and economic indicators (TEI) at TPP that are equipped with automated information-measuring systems (IMS) is carried out, as a rule, automatically. In this case, the values are obtained with a period of 15 minutes based on the current values of the process parameters averaged over this period. An approach is proposed to increase the accuracy of determining the values of operational TEC, including reducing the static and dynamic components of uncertainty, using the example of the gross coefficient of a boiler unit. The application of the described methods leads to a reduction in uncertainty, more rapid obtaining of TEC values, which favorably affects the equipment control mode.
