摘要: 介绍CPR1000核电机组核功率变化率(dΦ/dt)修正通道的设置原理以及修正参数的设置方法。并结合实际电厂的相关数据,利用最佳估算瞬态程序CATIA2进行了详细的论证分析。通过分析计算及电厂甩负荷至厂用电试验数据的对比,说明了本文通道修正参数设置的合理性,为后续CPR1000核电机组的参数论证打下基础。

Abstract: This paper describes the methodology and parameter definition of dΦ/dt correction channel of CPR1000. These correction parameters have been studied essentially by combining with real nuclear power plant design parameters and using best-estimated transient analysis code CATIA2. According to comparison with house-load test data from site, these correction parameters have been validated. This analysis process could also be used for the coming new CPR1000 projects.
