摘要： PURPOSE:To restrain the thermal stress within the range of specified value and obtain the minimum starting time by a method wherein a starting schedule is calculated, at the starting, according to a generator load when the generator load exceeds the specified value and the turbine rotor thermal stress exceeds the limited value. CONSTITUTION:At the starting of a steam turbine, a starting schedule calculating unit 3 stores a starting control command K from an operator and input signals P1-Pn of the electricity generating process required for the monitor control of the turbine via an input processing device 2 of a turbine starting control device 1. When a generator load exceeds the specified value, and a turbine rotor thermal stress exceeds limited value, also after passage of the specified time, said calculating unit 3 calculates the starting schedule according to the generator load. On the other hand, in case of other than said case, said calculating unit 3 calculates as usual the starting schedule as a function of a main steam temperature, a pressure and a turbine metal temperature, then starts the steam turbine via the starting control unit 4.

摘要： PURPOSE:To have safety drive of a turbine by calculating the thermal stress of the rotor in the exhaust part of a high pressure turbine and thereby calculating and indicating the consumption of the given life of rotor. CONSTITUTION:A seat 5 is carved at a position directly close to the labyrinth patching part 2 of the high-pressure external casing 4 of a turbine, and a thermocouple 6 is set and fixed in this seat 5 by boring a bottomed hole 5a from outside of the casing. Thereby the thermocouple 6 senses the approximate temperature of the labyrinth coupling part 2 with high accuracy. This detected temperature signal 103 is inputted to an automatic calculator 100 to calculate and indicate the thermal stress of the rotor 3. Thus safety drive of the turbine can be secured.

摘要： PURPOSE:To enable properly grasping brittle fracture strength by providing a temperature detector to detect the temperature in the center hole of a rotor shaft and the temperature near the surface of the rotor outer peripheral part, and a throttle valve to jet steam which has been brought under high pressure cooling. CONSTITUTION:Temperature detector 27b, 27a to detect the temperature in the center hole of a rotor shaft 19 in a turbine, and the steam temperature near the surface of the rotor outer peripheral part are provided. Both detected temperatures are sent to a heat stress arithmetic unit 32, and in case where the heat stress exceeds its allowable value, a command is sent from a controller 28 to a throttle valve 29. Steam 31 which has been brought under high pressure cooling is jetted in promper quantity from a diaphragm 30 through the throttle valve 29 toward the outer peripheral part surface of the rotor 19, and it cools the rotor to its proper temperature. Thus, while brittle fracture strength of the rotor is properly grasped, the stream turbine can be kept up its safe operation.

摘要： PURPOSE:To prevent mis-operation of each valve in high pressure turbine steam releasing line by controlling with each cam existed on one driving cam shaft, a plurality of turbine plant steam discharge control valves such as intercept bypath valve, etc. CONSTITUTION:Up-and-down movement of servomotor 29 which is driven by controlling oil 28, drive cam shaft 31 by means of rack 51 and pinion 30. On cam shaft 31, cam 32, 33, 34 and 36 which control intercept bypath valve 10 to be used when releasing steam existed inside of high pressure turbine to condenser, ventilator valve 12, intercept valve 14 and spill valve 35, are fixed, each providing with cam type to perform valve opening mode. By this can avoid mechanical motion lag on motion of each valve and insure supressing function on uprising of inner temperature of high pressure turbine.

摘要： PURPOSE:To regulate idling of a main-steam-cut-off-valve-bypass-valve for proper stroke and free from the idling of it at atarting for timely acceleration of a turbine. CONSTITUTION:Once an output of starting is thrown, a switch 13 is turned ON and a bypass signal is precedingly applied to a subtracter 7 which to regulate the idling of a main-steam-cut-off-valve-bypass-valve MSV-BV stroke. The resulting main- steam-cut-off-valve-bypass-valve MSV-BV makes dramatical stroke until the valve opens. The output signal of a regulator 4 is applied to the subtracter 7 in parallel with the bypass signal from the switch 13. Immediately after that, the main-steam- cut-off-valve-bypass-valve MSV-BV is opened to let steam into a high-, intermediate-, and low-pressure turbine of HP, IP, LP turbine so that a turbine can be given stable acceleration without delay.
