无扰切换在核电厂非安全级 DCS 平台上的实现及差异分析

摘要

本文阐述了核电厂采用的两种非安全级 DCS 系统实现闭环控制的方案，着重对闭环控制的无扰切换功能进行比较分析，并对两者差异形成原因以及设计理念讨论和分析。论证了 MACS6和 TXP 平台均可以实现闭环控制的无扰切换的功能。%The realization of closed-loop control in two different non-safety DCS systems(MACS6 and TXP) for nuclear power plant was described in detail.And the different analysis of bump-less switchover for the reason、design concept is also discussed.Finally,the conclusion is that bump-lessswitchover in MACS6 and TXP was realized.
