| 摘 要： | 针对当前核安全级数字化仪控系统（DCS）冗余切换功能测试方法缺乏、测试活动主要依靠人员经验的情况，提出了一种针对核安全级DCS设备的通用的冗余切换测试方法，通过设计机理分析，建立冗余切换测试基础故障模式，并对故障模式进行模式组合和系统状态变迁分析，完成对冗余切换测试场景、测试环境等整体方案的设计。通过在某核安全级仪控平台中的应用以及在核电厂的成功运行经验，对本测试方法的有效性进行了验证。结果表明，提出的冗余切换测试技术能够有效地发现设计缺陷，对设备冗余切换功能的出口质量控制具有实际应用价值。

| Abstract: | To solve the problems in current redundancy testing of nuclear safety Digital Control System (DCS), such as the lack of systemic technology, a testing method based on failure mode analysis was proposed for nuclear safety DCS redundancy function. The basic failure modes for redundancy testing were established through the analysis of the design mechanism, and were combined into different kinds of failure scenario. The overall testing method was then designed based on failure mode combinations and system state transition analysis under the failures, including the design of redundancy testing scenarios and testing environment. The validity of the testing method is validated through the successful application experience in a nuclear power station, which shows that the redundancy testing method proposed could effectively detect defects in product design and is valuable for the quality control of the redundancy function in nuclear safety DCS. |
