摘　　要：在核电站数字化仪控系统中,应用软件中的算法块是执行核反应堆安全功能的关键环节和重要组成部分。驱动类算法块作为应用软件的一部分,运行在控制器中,主要完成对现场驱动及控制类设备的控制。若该部分功能实现不正确,会导致现场设备异常启动或停止,不能正确地实现对现场设备的调节和控制。保证算法块功能运行的正确性,对于核电站现场设备的安全稳定运行具有重要意义。驱动类算法块功能结构复杂,且与现场操作流程及工艺密切相关。为了更贴近核电站现场实际应用场景,提出了一种基于场景分析法的核电仪控系统驱动算法块的测试用例设计方法。该研究对测试用例设计方法进行了分析和描述,有效保障了测试用例设计的充分性和完整性,并成功地将其应用到实际工程项目驱动算法块的测试中,取得良好的应用效果。In the digital instrument control system of nuclear power plant,the algorithm block in the application software is the key link and important part of implementing the safety function of nuclear reactor.As a part of the application software,the driver algorithm block runs in the controller,which mainly completes the control of the field driver and control equipment.If this part of the function is not realized correctly,it will lead to abnormal start or stop of the field equipment,and the regulation and control of the field equipment cannot be realized correctly.To ensure the correctness of the algorithm block function is of great significance for the safe and stable operation of the on-site equipment in nuclear power plants.The function structure of the driver algorithm block is complex,and it is closely related to the field operation process and technology.In order to get closer to the actual application scenario of nuclear power plant,a test case design method of driving algorithm block of nuclear power instrument control system based on scenario analysis method is proposed.In this study,the test case design method is analyzed and described,which effectively guarantees the adequacy and integrity of the test case design,and it is successfully applied to the test of the actual engineering project driven algorithm block,and obtains good application effect.
