针对核电机组实际启动前无法建立动态运行工况而导致无法对反应堆控制系统(RRC)的组态设计进行评估及分析的问题,介绍了利用反应堆热工水力仿真模型、Labview图形化虚拟仪表编程语言和DAQ数据采集技术研发的RRC仿真测试平台,通过将该测试平台与核电站的实际数字化仪表控制系统(DCS)机柜相连,对实际的RRC实施了单步和关联运行测试,实现了RRC功率运行或瞬态工况下的逻辑预演和动态评估,并逐一排查了大量设计错误或不符合项.岭澳二期核电站3/4号机组的应用实践证明,利用核电站仿真技术对RRC进行调试,可有效降低机组功率运行的大瞬态试验风险,缩短启动工期.

Based on the nuclear power thermal-hydraulic model, Labview graphical programming lan-guage and virtual instrument data acquisition technology, this paper describes a dedicate test platform to solve the problem that the reactor control system (RRC) can not be evaluated and analyzed far before the actual startup of the unit. By connecting the test platform to the nuclear Digital Control System (DCS), the step-by-step closed-looped test and global function test of RRC system were performed, the dynamic valida-tion and logical function demonstration for RRC were realized, and a lot of configuration mistakes of RRC and nonconformity were solved. The test for unit 3 of Ling'ao phase Ⅱ has proved that the implementation of nuclear power plant simulation in the start-up commissioning of RRC can greatly reduce the risk of normal power operation and great transient tests, with which the term of startup for overall unit test can be greatly shortened.
