| Abstract: | According to the vertical natural circulation steam generator, a mathmatic model is build by modularized mechanism modeling method. The mathmatic model includes 16 control volumes. According to the control volumes the mathmatic model with 12 state variables is created and deduced by lumped parameter method. The mathematical model of vertical natural circulation steam generator is resolved by Runge-Kutta method. The model is verified by simulation test. The mathmatic model can be used to analyze the dynamic characteristics of steam generator,and design the controller. It has a definite application value. |
