摘要
核电站数字化仪控系统存在系统风险。基于安全性理论,风险形成是一个传导过程,针对仪控系统失效这一概率事件,提出一级预警和二级预警的概念。基于特征向量的安全预警,可以合理描述系统风险的各种情况,并提高对DCS仪控系统问题的预警时间裕量,增加核电站的安全及可靠性。
The digital instrument control system of nuclear power station exists risk. Based on the theory of safety, the risk forming is a conduction process. For the failure probability of instrument control system, puts forward the concept of the first and second level of early warning. The safety early warning is based on feature vector. It is reasonable to describe system risk situations. The warning time of DCS instrument control system is improved. The safety and reliability of nuclear power plant are increased.
