摘　　要：本文从方家山DCS系统时钟网络出发,研究分析Mesh数据网络架构拆分后DCS一层时钟网络拆分设计,通过DCS系统最小化平台测试验证DCS系统时钟网络拆分可实施性,得到对“一机组运行,一机组停运”下DCS系统影响最小的时钟网络拆分方案。本方案可为同类型核电机组时钟网络变更改造提供重要经验反馈和技术支持,亦可为全数字化核电机组DCS系统时钟网络设计提供良好参考借鉴。This paper studies and analyzes the split design of the one-layer clock network of DCS after the split of Mesh data network architecture,the feasibility of clock network disassembly of DCS system is verified by the test of DCS system minimization platform,and the scheme of clock network disassembly which has the least influence on DCS system under the condition of“One unit running,one unit outage”is obtained.This scheme can provide important experience feedback and technical support for the modification of the clock network of the same type of nuclear power unit,and can also provide a good reference for the design of the clock network of the full-digital DCS system of the nuclear power unit.
