Abstract (en)
A computer-implemented method for analyzing the operation of power plant blocks, in which, on the basis of collected operational data, the deterministic models (202) of operation of individual blocks are examined and characteristics (203) of operational parameters are created. The selected operational parameters are examined by calculating for them the deviation of heat rate in time on the basis of the deterministic model and the characteristic of the parameter, destructions of exergy in various process points of the block are calculated; for various points of the process and for various power plant blocks, the calculated deviations of heat rate and the destruction of exergy are presented in a graphical form.
