Abstract

PURPOSE: To operate either of main steam flow rate or condensation flow rate in fixed flow rate, by providing only either of said main steam flow rate or condensation flow rate with variation even when bleed flow rate changes.
CONSTITUTION: Bleed pressure control signals, the output of a low-value preference circuit 33, are used as the input of an adder 20 through variable constants 35, added to speed control signals and utilized as steam regulating valve control signals. The bleed pressure control signals are used as the input of an adder 25, and produce bleed regulating valve control signals. The output of the adder 20 is compared with a set point of a main steam flow rate miximum set instrument 38 by means of an adder 37, and error signals are utilized as the input of a limiter 39. Either of main steam flow rate great operation or condensation flow minimum operation or operation except said operation is selected by means of a select circuit 40 in the output of the limiter 39.
