摘要
核电厂应急辅助决策系统数据接口众多,如果对应急系统接口考虑不足,可能会造成应急系统功能缺失,对应急响应造成影响。对核电厂应急系统的接口进行了梳理,明确了不同系统和应急系统间的通信方式和通信内容。依据信息安全的要求,生产控制大区(如全厂非安全级控制系统)向信息管理大区(如应急系统)传输数据应为单向通信。因此,设计了基于用户数据报协议(UDP)和数据摆渡的数据单向传输方案,以及基于超文本传输协议(HTTP)的数据双向传输方案。针对在应急演习期间,应急系统会将数据源切换为模拟机和人工预置数据的情况,设计了分布式控制系统(DCS)和模拟机的数据源切换方案以及人工预置数据模板。通过对核电厂应急系统数据接口的梳理和通信方案的设计,为后续新建核电厂的核电厂应急系统建设提供了指导,降低了应急系统现场调试数据接口的风险。
There are many data interfaces in the emergency auxiliary decision⁃making system of nuclear power plants,and if insufficient consideration is given to the interfaces of the emergency system,it may result in the lack of functions of the emergency system and affect the emergency response.The interfaces of the emergency system of nuclear power plants are sorted out,and the communication methods and communication contents between different systems and emergency systems are clarified.According to the requirements of information security,the transmission of data from the production control area(e.g,.plant⁃wide non⁃safety level control system)to the information management area(e.g,.emergency system)should be unidirectional communication.Therefore,a unidirectional data transmission scheme based on user datagram protocol(UDP)and data ferrying,and a bidirectional data transmission scheme based on hypertext transfer protocol(HTTP)are designed.Aiming at the situation that the emergency system will switch the data source to the simulator and the manual preset data during the emergency exercise,the data source switching scheme of distributed control system(DCS)and simulator as well as the manual preset data template are designed.By sorting out the data interfaces of the emergency system of nuclear power plants and designing the communication scheme,it provides guidance for the construction of the emergency system of the subsequent new nuclear power plants and reduces the risk of debugging the data interfaces of the emergency system on site.
