FIELD: engines and pumps.
SUBSTANCE: invention is related to power engineering and may be used for automatic control of steam-gas plants (SGP) automatic control. According to invention, steam pressure detector is connected to one of SGP capacity controller inlets via differentiator upstream control valves of steam turbine (ST), and generator of anticipatory signal of ST controller is arranged in the form of two summators, to inlets of the first of which, outlets are connected from identifiers of current values of gas turbines (GT) capacities, and to inlets of the other - via damper - identifier of current ST capacity value, outlet of the first summator via another damper and outlet of SGP capacity setting generator.
EFFECT: invention makes it possible to increase quality of control as a result of simplification of SGP control system adjustment and accuracy of control due to the fact that additional signal is sent to ST controller on unbalance between specified and actual capacity of SGP.
