Abstract

PURPOSE: To prevent a linked tripping of the whole plant at the time of occurrence of a trouble anywhere in a generating plant, which has two or more boilers, turbines and generator machines and feeds a varying amount of power, by furnishing an emergency working device separate from the controller of conventional type.
CONSTITUTION: This emergency working device is composed of an expected load calculator 5 to put out the regular load upon receiving an emergency input signal 4 from the plant 2, a turbine load and air bleeding calculating/setting device 8 to set a target value for the turbine output and the amount of bled air, and load selecting and shutoff setting device 9 to set the shutoff of the air bleeding and electric load in accordance with the sort of emergency. Further this is equipped with a steam balance calculator 10, a air bleeding mode calculator 11, a by-pass valve opening/closing calculator 12, a boiler evaporation calculator 13, a relay setting signal generator 14 whose input is connected with the outputs of the turbine load and air bleeding/setting device 8 and the load selecting and shutoff setting device 9, and an emergency action signal generator 15 connected with the inputs to the plant 2.
