摘要:通过对压水堆核电站稳压器实际运行特性的分析研究,在合理简化与假设的基础上分别对稳压器蒸汽区以及液体区建立质量和能量守恒方程,建立一个两区不平衡的稳压器模型。然后通过模块封装组建成稳压器水位和压力控制系统,最后通过仿真对稳压器主要参数进行动态特性分析,仿真结果符合理论分析,所建模型合理。

Abstract,By analysis of the actual operating characteristics of pressurizer in pressurized water reactor (PWR) nuclear power plant and based on some reasonable simplification and basic assumptions, the quality and energy conservation equations about pressurizer s steam zone and the liquid zone are set up.The purpose of this paper is to build a pressurizer model of two imbalance districts. Water level and pressure control system of pressurizer is formed though model encapsulation. Dynamic simulation curves of main parameters are also shown. At last, comparisons between the theoretical analysis and simulation results show that the pressurizer model of two imbalance districts is reasonable.
Key words:pressurizer; pressure and water level control system; modeling; simulation
