Research on water level control calculation of steam generator in nuclear power plant

Considering the steam generator's structure and working principle of water level control, a mathematical model was proposed for studying water level control. based on this model, a calculation code SGWLC was programed, which was used to dynamically simulate the transient behaviors of steam generator's parameters while water level was controlled. Using this program, the characteristics of steam generator's parameters were calculated and analysed, when the water level was controlled or uncontrolled under some disturbing conditions. The calculated results are in good agreement with the theoretical analysis.
