摘　　要：核电站正常运行期间,DAS系统的表现与系统发生拒动的表现相同,为了发现系统中存在的潜在故障,在DAS投运时,功能正常运行,设计了一套定期试验方案。本方案与模拟系统的试验方案相比,逻辑功能试验采用自动执行试验用例的方案,接口试验方面,结合Fit Rel平台的特点,采用可视化显示单元(VDU)进行试验信号注入与试验结果的查看,简化了试验方法,提高试验效率。本方案已经在工程样机中完成验证,且应用于某核电站的多样性驱动系统中。该方案对后续的数字化多样性驱动系统定期试验方案的设计具有借鉴意义。During NPP normal operating, diverse actuation system performance is as same as refuse operation. In order to find DAS potential faults and make sure DAS can execute actuation function when it is in operation, we design a periodic test scheme. This scheme designs based on digital system design. Compared with the test scheme of analog system, the logic function test using automated test cases, the test method of logic test improves the test efficiency and reduce the probability of human error, combining the characteristics of FitRel platform. The interface test injects test signal and view the results of tests by using visual display unit （VDU）, which simplified test method, improve the test efficiency. The test scheme has finished test on the prototype and it has been applied in a nuclear power plant in DAS. The scheme has a reference significance for subsequent periodic test of diverse actuation system.
