核电厂数字化控制系统调试模式初探

The Discussion on Commissioning of DCS of Nuclear Power Plant

AP1000分布式数字控制系统的测试是以自下而上的方式组织的,从初级模块和应用软件开始,然后是设备和系统,高一级测试建立在低一级测试结果的基础之上,最后证明整个仪控系统有效可用。由于在工厂环境里进行了大量的测试,只要系统组态的可追溯性得到维护,并运用相应的回归分析和重新测试来验证设计变更,则许多工厂测试不需要在电厂调试中完全重复进行。上述测试策略的变化,决定了核电厂控制系统调试内容的变化,对应的仪控调试管理模式应做适应性调整,即实现仪控技术管理的一体化,以便仪控调试人员提前参与工厂测试,不再将仪控技术管理职责分散到设计、采购、安装、调试等部门,而是集中在某一个部门统筹管理。

AP1000 digital distributed control system testing is organized from a＂bottom-up＂approach, starting at low-level modules and application software, and then building up as the equipment and system. Tests build upon the results of previous test activities. Finally, the full DCS system is demonstrated to be work together. Due to extensive tests of the DCS system are in a factory environment, if traceability of the system configuration is maintained, with corresponding regression analysis and retesting utilized to verify changes to the design, then much of this factory testing does not need full repetition in a site environment. As the test strategy is changed, the commissioning of nuclear power plant digital control system is also changed, so that the management of the commissioning should be adjusted, i.e. IC technical management should be integrated, and IC commissioning staff will participate in factory test. That means IC technical management will no longer be distributed into design department, procurement department, installation department and commissioning department. One department will be responsible for overall IC technical management.
