基于can總線的變電站測控系統(tǒng)的設(shè)計與研究2-全文預(yù)覽
【正文】 動化的初級形式，尚不能稱為綜合自動化系統(tǒng)。該類系統(tǒng)實際上是在常規(guī)的繼電保護及二次接線的基礎(chǔ)上增設(shè) RTU裝置以實現(xiàn)“四遙”。由南京電力自動化研究院研制的第 l套適用于綜合自動化系統(tǒng)的成套微機保護裝置 ISA于1993年通過部級鑒定以后，各地電網(wǎng)逐步開始大量采用變電站綜合自動化系統(tǒng)。較遠動裝置采用微機技術(shù)滯后且更為復(fù)雜的繼電保護全面采用微機技術(shù)成為現(xiàn)實。這些稱之為集中式的弱電控制、信號、測量系統(tǒng)的研制成功和投運為研制微機化的綜合自動化裝置積累了有益的經(jīng)驗。二則目前高校、科研院所對現(xiàn)場總線及FCS技術(shù)從研究開發(fā)到應(yīng)用均處拋步階段，F(xiàn)cs在電力生產(chǎn)部門應(yīng)用不多，應(yīng)用與開發(fā)的技術(shù)很不成熟，在認(rèn)識和經(jīng)驗方面有很大的欠缺，需要在研究和實踐中不斷探索、不斷總結(jié)經(jīng)驗，將FCS的技術(shù)和應(yīng)用逐步完善起來?，F(xiàn)有的變電站綜合自動化設(shè)備中的設(shè)備層中的測控單元尚采用單片機技術(shù)，盡管晶振頻率逐步提高、運算速度大大加快，但單片機的結(jié)構(gòu)決定了無法進行快速數(shù)字信號處理、計算多個現(xiàn)場的數(shù)據(jù)，現(xiàn)有設(shè)備在速度上、精度上尚有不盡人意之處。關(guān)鍵詞： CAN總線 微控制器 網(wǎng)絡(luò)適配器CAN bus based design of substation monitoring system Absrtact Automation field bus is today one of the hot technology, known as the automation of puter local area network. It was a distributed control system between the nodes achieving realtime, reliable data munications to provide a strong technical support. Substation information and data sharing and the use of reliable, practical and efficient munication networks and protocols, to optimize the function of substation automation system to improve the level of substation automation system. With the continuous expansion of power network and puter monitoring and control technology, the rapid development of fieldbusbased control system will widely used in power system substations. CAN field bus the thesis based on research it in the substation automation system theory and practical methods of measurement and control network for the shortings of traditional design of a CAN bus is posed by the Fieldbus control network, and discussed in detail the CAN bus technology and its implications for substation automation system. Through a single chip microcontroller for the hardware and software design, making the whole substation within the system to achieve reliable munication between devices possible for the eventual unattended substation provides the conditions for the model..Keywords: CAN bus Microcontroller Netword card 目 錄第一章、緒論 9 9 10 10第二章CAN總線簡介 12 CAN的技術(shù)特點 12 連接和傳遞方式 12 CAN報文傳輸 12 CAN控制器 12 CAN總線系統(tǒng)的一般組成 12第三章、 基于CAN總線變電站監(jiān)控系統(tǒng)的總體設(shè)計 12 CAN總線節(jié)點（下位機）設(shè)計 12 CAN總線節(jié)點（上位機）設(shè)計 12第三章、CAN總線節(jié)點（下位機）設(shè)計 13 14 12 CAN通信模塊設(shè)計 14 14 14 C
