Abstract

PURPOSE:To prevent the feed of extracted steam containing a surplus quantity of heat and to improve the efficiency of the interior of a turbine, by a method wherein the set value of an extraction pressure is varied so that the temperature of extraction steam extracted from a steam turbine high pressure part is maintained at a specified value. CONSTITUTION:Steam fed from a steam turbine high pressure part 2 to a steam turbine low pressure part 4 is controlled by means of an extraction steam regulating valve 3. The pressure of steam extracted from the steam turbine high pressure part 2 is detected by a detector 10, and a set value is generated by a generator 12. The detecting value of an extraction pressure and the set value are compared with each other and computed by means of an adder 11, and after an extraction steam pressure control signal 13 is inputted as an extraction steam regulating valve control signal 20 to an electrohydraulic converter 21, it is outputted to the extraction steam regulating valve 3. In this constitution, a system 25 is provided for varying the set value of an extraction steam pressure so that the temperature of extraction steam is maintained at a specified value. The system 25 is formed with an extraction steam temperature detector 26, a set value generator 27, and an adder 28.
