基于ADACS_N平台的DCS一二层状态不一致问题分析与解决

Analysis and Solution of Inconsistency Between DCS Level 1 and Level 2 Based on ADACS_N Platform

ADACS_N平台作为电站操作和监视系统(DCS二层)的应用平台,实现对整个电站的监视和控制功能。基于ADACS_N的DCS二层系统,若出现设备状态或工艺变量与DCS一层的实际状态或参数值不一致,将严重影响操纵员对机组状态的监视与控制。文章对基于ADACS_N平台的DCS一、二层状态不一致问题进行深入分析,通过一系列工作方案的执行,最终分析得出基于ADACS_N平台的DCS一、二层状态不一致的根本原因及解决方案,有效解决了重大隐患,对基于ADACS_N平台的核电机组的DCS的稳定运行及软件优化有积极作用。

As an application platform of Plant Control and Monitor System （DCS Level 2）, the ADACS_N platform is used to monitor and control the whole plant. When the DCS Level 2 system, which based on the ADACS N platfom~, occurs inconsistency with the DCS Level 1 system on the Devices State and Technology Parameters, it will seriously affect the operator to monitor and control the plant state. This article makes deep analysis of the inconsistency between DCS Level 2 and Level I system, and obtains the root causes and solutions with a series of schemes implementation, which has made a great progress for the steady operating of DCS as well as software improvement for the follow-up units.
