Abstract
PURPOSE: To lessen the pressure given to the apparatus to follow and the fluctuation of temperature at the time of a sudden stop of the turbine by providing a turbine bypass valve whose opening is set on the basis of an adjusting valve opening signal and an extraction or exhaust pressure signal.
CONSTITUTION: A signal 20 for opening of the turbine bypass valve 7 equivalent to the flow rate passing the turbine is set by a converter 15 for the opening of an adjusting valve and by an opening-function generator 16. A pressure signal 27 is set by an extraction or exhaust pressure converter 25 and by a pressure adjusting meter 26. At the time of a trip of the turbine, a quick-open cutoff valve 6 is opened, the opening signal 20 and the pressure signal 27 are selected by a high-value selector 28, and the turbine bypass valve 7 is controlled by being switched more smoothly from the opening signal 20 to the pressure signal. An attemperator 8 reduces the temperature of bypass steam and renders the same to the following apparatuses. In this way, no fluctuation of presure and temperature is given to the following apparatuses at the time of the trip of the turbine.
