摘　　要：针对CPR1000直立式自然循环蒸汽发生器虚假水位现象进行研究,讨论了不同功率水平下的蒸汽发生器虚假水位现象,并进一步研究了水位控制方案对虚假水位的调节作用。结果表明,水位偏差与汽水失配串级控制方法对虚假水位现象具有良好的调节效果;在手动控制模式下,操纵员控制给水阀门应考虑到虚假水位的影响,以避免虚假水位现象触发报警信号甚至停堆保护信号。The false water level phenomenon of the vertical natural-circuit steam generator of CPR1000 has been investigated.The discussion on the false water level phenomenon under different power steps has been conducted,and based on which,several water level control methods have been discussed.The result shows that the cascade control of the water level deviation and steam-water mismatch has positive effect on the control of the false water level phenomenon.The operator should take the false water level into consideration when it comes to the manual control,in order to avoid triggering the alarm even the trip signal.
