Abstract

PURPOSE: To perform stable control of water supply by controlling the revolving speed of a condensate pump according to the deviation of the revolving speed signal, which is determined from the sensed water supply pump suction pressure on the water supply system, from the set value signal, and thereby holding the suction pressure of a water suction pump constant.
CONSTITUTION: The pressure of condensate from a water condenser 1 is boosted by a condensate pump 2, and the condensate is supplied to a nuclear reactor 5 through a motor-driven pump 3 at the time of low load and through a turbine pump 4 at the time of high load, and there the condensate is heated to become a high pressure vapor to drive a turbine. The suction pressures of pumps 3, 4 are sensed 13 and fed to a revolving speed calculating device 14 as a pressure signal, and there the revolving speed is computed and fed to a revolving speed control device 15 as a revolving speed signal. This revolving speed control device 15 determines the control deviation between the given revolving speed signal and the predetermined set value signal, and the result from computation is given to the motor 16 of the condensate pump 2 as a revolving speed command signal. This holds the suction pressure of the water supply pump 2 constant, and water supply control is carried out stably.
