Temperature fields in electric energy generation may lead to the mechanical disbalance of an already balanced rotor. The authors collected information in a number of Serbian steam power plants and they realized the existence of the problem. On the grounds of the relevant physical aspects they propose a mathematical model for identifying temperature fields in a turbo-generator rotor, and they suggest the optimum control by which the unwanted effects are eliminated.

Pole temperaturowe w wytwarzaniu energii elektrycznej może prowadzić do nierównowagi mechanicznej wirnika będącego w stanie równowagi. Autorzy zebrali informacje w wielu elektrowniach cieplnych na terenie Serbii i stwierdzili istnienie tego problemu. Biorąc pod uwagę istotne czynniki fizyczne zaproponowano model matematyczny dla celów identyfikacji pól temperaturowych w wirniku turbogeneratora i na jego podstawie dobrano sposób sterowania optymalny ze względu na eliminacje niepożądanych zjawisk.
