摘要
针对海阳核电首台AP1000核电汽轮机的主保护组成、跳闸项目及逻辑条件的形成,进行介绍及优化。通过在逻辑条件形成中引入仪控设备故障信号判断、坏信号剔除及逻辑条件优化等方法,提高仪控保护系统的可靠性,减少设备发生误动和拒动的概率。
This paper introduces the composition of the main protection and the formations of trip items and logical conditions of the first AP1000 nuclear power steam turbine in Haiyang Nuclear Power Plant.In addition,it puts forward relevant optimizing methods such as the introduction of the I&C equipment fault signal judgment,the bad signal removal and the logical condition optimization in the formation of logical conditions,which can enhance the reliability of I&C protection system and reduce the probability of equipment malfunctions and refusals.
