摘要：核電站模擬量顯示精度是對模擬量點(diǎn)在操作員站上顯示的數(shù)據(jù)總位數(shù)和小數(shù)位數(shù)的要求，其準(zhǔn)確性直接影響操作員對于核電站運(yùn)行工況的判斷。在核電站DCS系統(tǒng)中存在近萬個(gè)模擬量點(diǎn)需要在操作員站上進(jìn)行顯示，每個(gè)點(diǎn)的顯示精度都要依據(jù)設(shè)定的規(guī)則進(jìn)行測試。目前行業(yè)內(nèi)采用的測試方式為人工逐個(gè)測試，測試質(zhì)量不理想且需要耗費(fèi)大量的時(shí)間。本文通過改變測試方法并開發(fā)工具，提出了一種新的模擬量自動(dòng)化測試方法，以替代傳統(tǒng)人工測試。經(jīng)實(shí)際項(xiàng)目試驗(yàn)，該方法可以大大提升測試效率和準(zhǔn)確性。

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.

Key words: Nuclear power plant DCS; Analog accuracy; VBA; Automatictest
