FIELD: power industry.
SUBSTANCE: operating method of heat extraction turbine plant with steam reheat and consisting of turbine that includes IP and LP cylinders with reheated steam supply to IP cylinder, chamber of heating extraction with steam discharge from the chamber to delivery water heater and steam inlet member of LP cylinder where steam temperature is measured in heating extraction chamber, compared with maximum allowable value and when maximum allowable value is exceeded, steam inlet members of LP cylinder are opened until steam temperature in heating extraction chamber is compared with maximum allowable value.
EFFECT: invention allows providing steam temperature decrease in heating extraction chamber in variable conditions without reducing the turbine plant economy.
