Note:
It was shown that application of nonequilibrium thermodynamics in a new field of energy transformation processes permit to build (in linear approximation) the mathematical model of power plants, which describs kinetic of such proceses and consists of its phenomenological laws and singlevaluedness conditions. This model permits to introduce some criterian of similarity of power plants, to obtain a criterion's equation connecting their efficiency and output power with load and soundness, as well as to build the universal load characteristics of these plants. The similarity of power plants permits to transfer the results of studies from one to the other (new) power plants, to prognosticate their effectiveness, to build the individual load characteristics of various power plants using data of their test for one of the modes, to find their regime with maximum power and maximum efficiency etc. The application examples of power plants similarity theory were given. Neccesity of correction of the some conceptions of the classical heat machines theory was shown.
