FIELD: power industry.
SUBSTANCE: power plant is controlled by steam temperature maintenance by temperature control of heat carrier of the first circuit at the steam generator inlet as per a signal of deviation of its measured value from its setpoint. Steam pressure is controlled by correction of the specified feed water flow rate as per a signal of deviation of the measured steam pressure from its setpoint with correction of temperature setpoint of heat carrier of the first circuit at the steam generator inlet as per a signal of deviation of the measured steam temperature from its setpoint. Correction of temperature setpoint of heat carrier of the first circuit at the steam generator inlet is activated when the measured steam temperature of a corrector activation setpoint is achieved.
EFFECT: excluding self-oscillations of a system due to mutual interlocking between correction of temperature setpoint at the steam generator inlet and correction of the specified feed water flow rate.
