Abstract

Abstract

Accurately obtaining the dynamic characteristics of natural circulation steam generator (SG) water level has important guiding significance for the design of SG water level control system. In this paper, based on the equations of mass conservation, energy conservation and momentum conservation of fluid, the sixteenth-order nonlinear dynamic model (N-M) of SG is established; based on the perturbation theory, the transfer function model (T-M) of SG is obtained by linearizing N-M; the same disturbance is introduced to the two models on the MATLAB/Simulink simulation platform, and the simulation results show that the transient results of the two models are consistent and can correctly reflect the water level dynamic characteristics of SG. The study of this paper is helpful to understand the mechanism of SG water level change and provide an analysis tool for the design of SG water level control system.
