| 摘 要： | 对北京核电厂模拟培训中心的压水堆模拟器稳压数学模型作了改进。原稳压器数学模型采用修正的平衡态模型，对于快速瞬变过程，不能满足模拟的逼真度要求。改进后的模型采用三区非平衡态模型，考虑了稳压器内汽泡上升、液滴下降和喷淋凝结等传热传质过程，实现了联机实时运行。

| Abstract: | The improvement of mathematical model of the pressurizer for a PWR nuclear power plantsimulator, located in Beijing Nuclear Power Plant Simulation Training Center, is presented. Theoriginal model is a revised equilibrium model. It couldn' t satisfy the requirement of simulation fi-delity for the fast transients. The improved pressurizer model is a three region, non-equilibriummodel with bubble rise and condensate drop dynamics, taking into consignation the spray and con-densate on spray heat and mass transfer processes in the pressurizer. The model was implanted inthe system and real-time simulation was realized, and satisfactory simulation effect was obtained.In addition, study on the sensibility of the simulation results to the computational time incrementis also performed. |
