Beschreibung
Zusammenfassung:	The embodiment of the invention provides a temperature control system and method for turbine blades. A gas tank communicates with a cooling channel of a guide vane through a cooling pipeline, and a cooling valve is arranged on the cooling pipeline; the first temperature measuring unit is used for measuring the temperature of the guide vane; when the temperature of the guide vane is larger than a preset guide vane temperature threshold value, the control unit controls the cooling valve to be opened, gas in the gas tank circulates in the cooling pipeline and the cooling channel, and the guide vane is cooled; the gas tank is communicated with a suction channel on the movable blade casing through a suction pipeline, and a suction valve is arranged on the suction pipeline; the second temperature measuring unit is used for measuring the moving blade temperature of the moving blade; when the temperature of the movable blade is larger than a preset movable blade temperature threshold value, the control unit controls
