摘要(Abstract)：

甩负荷特性是衡量核电机组安全稳定运行能力的重要标准,因而甩负荷试验是压水堆(pressurized water reactor,PWR)核电厂调试阶段必不可少的试验项目,在不同功率水平下运行的核电机组表现出不同的甩负荷特性。根据核电机组的实际运行特性,建立压水堆核电机组模型,仿真模拟多种功率水平下核电机组的甩负荷工况。在此基础上加入旁路蒸汽排放系统和汽门快关系统,对压水堆核电机组的甩负荷保护进行研究。仿真结果表明,功率水平越高,机组甩负荷引起的扰动越大,必须装设保护系统;旁路蒸汽排放系统和汽门快关系统都能够对核电机组产生有效的保护作用,前者对核电机组反应堆、热力系统参数保护作用较显著,后者对汽轮机转速飞升抑制作用较显著。
