核电安全级数字化仪控系统T2试验方案研究

Research on T2 Test Strategy for Nuclear Safety-class Digital Instrument and Control System

研究了基于Tricon平台的RPS系统T2试验方案,分析了Tricon平台"点对点"的自诊断能力对T2试验方案的作用,进而搭建基于VBA的第三方仿真平台验证该试验方案的正确性。通过与基于其他平台的RPS系统T2试验方案的对比分析,归纳出基于Tricon平台的RPS系统T2实验方案的优缺点并提出了相应的改进措施。论文中试验方案所采用的设计理念同样适用于基于其他DCS平台或FPGA平台的RPS系统T2试验。

This paper studies Tricon- based RPS T2 test strategy and the effects of ＂ Point to Point＂ self- diagnostic capacity for Tricon platform on T2 test strategy are analyzed. And then,the third- party simulation platform based on VBA is established to verify the test strategy. Through comparing the test strategy with that based on other platform,the paper summarizes the T2 test strategy’s advantages and disadvantages and proposes the related improvement measures. The design concepts in this kind of test strategy are also suitable for RPS T2 test which is based on other DCS or FPGA platforms.
