小型压水堆核电厂通常采用结构紧凑的直流蒸汽发生器,在甩负荷工况下,其蒸汽压力急剧升高.为防止蒸汽压力过高对设备造成损坏,本文在建立小型压水堆一、二回路设备模型以及控制系统的基础上,分别基于压力模式、温度-压力和功率-压力模式设计蒸汽排放控制系统,并在甩负荷工况下开展小型压水堆系统的仿真研究.结果表明,在甩负荷工况下,与压力模式相比,温度-压力和功率-压力模式能够有效减小蒸汽压力的超调量.
Small pressurized water reactor nuclear power plant usually uses compact once-through steam generator,which has dramatically increased steam pressure under load rejection condition.In order to prevent damage to the system equipment caused by excessive steam pressure,based on the establishment of the mathematical model and the control system for the primary and secondary equipment of SPWR,this paper designs the steam dump control system based on pressure mode,temperature-pressure mode and power-pressure mode respectively,and carries out simulation research of SPWR system under load rejection condition.The results show that under load rejection condition,the temperature-pressure mode and power-pressure mode can effectively reduce the steam pressure overshoot compared with the pressure mode.
