FIELD: control systems for steam boilers.
SUBSTANCE: method comprises automatic control of the mechanism for control of turbine valve, frequency in the power system, steam pressure in the turbine, and active power. The control signal from the frequency meter is fed to the main controller through the frequency controller whose control signal is fed to the mechanism for control of the turbine valve. The steam pressure and active power is controlled by feeding signals from the main controller.
EFFECT: enhanced reliability.
