In this paper the model of computation of steam nozzle control systems with the given consumption of a working medium is considered, in which the task of shut-off elements positioning of control valves has been solved with the support of combinatorial algorithms. Thus the loading between the nozzle control systems segments of adjusting stage distributes in such a manner that the maximum possible power capacity of an adjusting stage is reached for each given steam consumption. The model describing joint operation of steam nozzle control system, the adjusting stage and the flow path of multicylinder steam turbine has been reviewed and analyzed.
