摘要：核电站模拟量显示精度是对模拟量点在操作员站上显示的数据总位数和小数位数的要求，其准确性直接影响操作员对于核电站运行工况的判断。在核电站DCS系统中存在近万个模拟量点需要在操作员站上进行显示，每个点的显示精度都要依据设定的规则进行测试。目前行业内采用的测试方式为人工逐个测试，测试质量不理想且需要耗费大量的时间。本文通过改变测试方法并开发工具，提出了一种新的模拟量自动化测试方法，以替代传统人工测试。经实际项目试验，该方法可以大大提升测试效率和准确性。

Abstract: The accuracy of the analog display quantity in nuclear power plant is the requirement of the total number and fractional number of the data displayed on the operator station, and its accuracy directly affects the operator's judgment on the operation of nuclear power plant. There are nearly ten thousand analog points in the DCS system of nuclear power plant, which need to be displayed on the operator station. The display accuracy of each point needs to be tested according to the set rules. At present, the test method used in the industry is manual test one by one, the test quality is not ideal and it takes a lot of time. By changing the test method and developing the tool, this paper proposes a new automated test method of analog quantity precision to replace the traditional manual test method. Through the actual project test, this method can greatly improve the test efficiency and accuracy.
