Research on Digital Upgrade Verification Platform Scheme for Simulation Control System of Daya Bay Nuclear Power Station

根据大亚湾核电站现有模拟控制系统的范围与实际情况,分析了信号配置、接口类型以及典型控制回路。结合第3个10年大修控制系统数字化升级的需求,提出了验证平台的技术要求,并搭建了基于数字化控制系统(DCS)小系统、工艺仿真系统与集中控制模拟量机柜(KRG)系统的验证平台;针对具体的验证内容,给出了详细的验证方案。利用验证平台开展相应的验证工作,可有效地识别改进前后的平台差异性,保证数字化升级的顺利实施。

According to the scope and actual situation of the existing simulation control system in Daya Bay Nuclear Power Station, the signal configuration, interface type and typical control loop are analyzed. In this paper, the technical requirements of the verification platform are put forward, and the verification platform based on DCS system, process simulation system and KRG system is set up. The specific verification contents are also given in detail. Using the verification platform to carry out the corresponding verification work, the differences before and after the improvement of the platform can be effectively identified to ensure the smooth implementation of digital upgrades.
