気タービン制御装置。 The extraction turbine has a turbine high pressure section and a turbine low pressure section, and the steam from the turbine high pressure section is supplied to the process section, and the steam from the turbine low pressure section is used for power generation. A main control valve is provided at the inlet, and a bleed control valve is provided at the inlet of the turbine low pressure section. In this bleed air turbine control device, which is operated by the opening/closing signal generated by the bleed air control valve calculation section based on the bleed steam pressure signal, a relay circuit is provided to detect the stop when the process section is stopped, and the above bleed air A hold circuit is provided when adding the vapor pressure signal to the speed signal, and in the event of an emergency stop of the process section, the signal from the relay circuit is sent to the hall circuit to hold the extracted steam pressure signal. Extraction turbine control device.
