Research on the Condensation and Feedwater Control System for Nuclear Power Plant
(0) In order to study the mechanism of the condensation and feedwater system of nuclear power plant, some simplified mathematic models are presented. The controlling principle of condensation and feedwater control system is explained, and their controllers are designed. Matlab/Simulink module is used for the simulation, result shows that the water level control system of steam generator could make the feedwater flow rate well track the change of the steam flow rate, reduce the false action of the feedwater valve and make the water level keep invariant The control system of the vacuum and condensate subcooling degree of the condenser could timely regulate the flow rate of cooling water. Thereby, the vacuum and condensate subcooling degree could be limited in certain range. The validity of the control system is proved which could provide reference for the design of the condensation and feedwater control sytem of nuclear power plant
