【摘要】：核電站數(shù)字化儀控系統(tǒng)(Digital Control System,簡(jiǎn)稱DCS)是核電站的信息神經(jīng)和控制中樞,對(duì)于保證核電站安全、可靠、穩(wěn)定和經(jīng)濟(jì)運(yùn)行以及提升生產(chǎn)管理水平都起著至關(guān)重要的作用。但長(zhǎng)期以來這一關(guān)鍵系統(tǒng)卻被國(guó)外供應(yīng)商壟斷,國(guó)內(nèi)已經(jīng)投運(yùn)的田灣核電站和嶺澳二期核電站均采用的是AREVA的安全級(jí)數(shù)字化平臺(tái)TXS和SIEMENS的非安級(jí)全數(shù)字化平臺(tái)TXP,這種現(xiàn)狀不符合國(guó)家推進(jìn)核電設(shè)備國(guó)產(chǎn)化的戰(zhàn)略要求,為此實(shí)現(xiàn)核電站數(shù)字化儀控系統(tǒng)設(shè)備國(guó)產(chǎn)化和設(shè)計(jì)自主化迫在眉睫。目前國(guó)內(nèi)的新建核電站已經(jīng)開始采用國(guó)內(nèi)的數(shù)字化儀控系統(tǒng)。 本文作者在核電站非安全級(jí)數(shù)字化儀控系統(tǒng)國(guó)產(chǎn)化及自主化工作實(shí)踐的基礎(chǔ)上,對(duì)核電站數(shù)字化儀控系統(tǒng)進(jìn)行了深入研究,取得了一定的成果,目前采用國(guó)內(nèi)自主知識(shí)產(chǎn)權(quán)的非安全級(jí)數(shù)字化儀控系統(tǒng)已經(jīng)成功地應(yīng)用于我國(guó)核電站。 本篇論文的第一部分主要從DCS系統(tǒng)發(fā)展概況、系統(tǒng)應(yīng)用、系統(tǒng)組成和系統(tǒng)特點(diǎn)幾個(gè)方面介紹了核電站儀控系統(tǒng)的發(fā)展,使人們對(duì)核電站數(shù)字化儀控系統(tǒng)有了進(jìn)一步的了解。第二部分主要分析研究了國(guó)內(nèi)典型壓水堆核電站數(shù)字化儀控系統(tǒng)的安全分級(jí)原則和安全分級(jí)方法。第三部分對(duì)國(guó)內(nèi)外壓水堆核電站數(shù)字化儀控系統(tǒng)的實(shí)現(xiàn)方案進(jìn)行了介紹,并從系統(tǒng)設(shè)計(jì)、設(shè)備研制和結(jié)構(gòu)設(shè)計(jì)等方面提出國(guó)內(nèi)的非安全級(jí)數(shù)字化儀控系統(tǒng)所進(jìn)行的優(yōu)化和創(chuàng)新,這些優(yōu)化和創(chuàng)新已經(jīng)成功地應(yīng)用到紅沿河核電站和寧德核電站中。
[Abstract]:(Digital Control System, is the information nerve and control center of the nuclear power plant, which plays an important role in ensuring the safety, reliability, stability and economic operation of the nuclear power plant as well as improving the level of production management. But for a long time this key system has been monopolized by foreign suppliers. Both the Tianwan Nuclear Power Station and the Lingao II Nuclear Power Station, which have been put into operation in China, use TXS, the safety grade digital platform of AREVA, and the non-safety grade full-digital platform, TXP, which is not in line with the national strategic requirement of promoting the localization of nuclear power equipment. Therefore, it is urgent to realize the localization of nuclear power plant digital instrument and control system equipment and design autonomy. At present, the domestic new nuclear power plant has begun to use the domestic digital instrument control system. On the basis of the localization and autonomization of the non-safety grade digital instrument and control system in nuclear power plant, the author has made a deep research on the digital instrument and control system of the nuclear power plant, and has achieved certain results. At present, the non-safety digital instrument and control system with domestic independent intellectual property rights has been successfully applied to nuclear power plants in China. The first part of this paper mainly introduces the development of instrument and control system in nuclear power plant from the aspects of DCS system development, system application, system composition and system characteristics, which makes people have a further understanding of digital instrument control system in nuclear power plant. In the second part, the safety classification principle and safety classification method of the digital instrument and control system of domestic typical PWR nuclear power station are analyzed and studied. In the third part, the realization scheme of digital instrument and control system for PWR nuclear power station at home and abroad is introduced, and the optimization and innovation of domestic non-safety grade digital instrument and control system are put forward from the aspects of system design, equipment development and structure design. These optimizations and innovations have been successfully applied to the Hongyan River and Ningde nuclear power stations.
