【正文】 這將減少投資提高可靠性,微機(jī)保護(hù),成熟的通信和現(xiàn)場(chǎng)總線技術(shù)是電氣系統(tǒng)綜合自動(dòng)化的技術(shù)保證。 因?yàn)橐y(tǒng)一現(xiàn)場(chǎng)總線系統(tǒng)很困難,解決這一問題的一個(gè)方法是把電力系統(tǒng)分割成一些子系統(tǒng)?,F(xiàn)如今工業(yè)以太網(wǎng)絡(luò)變成了新的熱點(diǎn) 。這篇論文分析的是發(fā)電廠電氣系統(tǒng)的現(xiàn)狀以及提出了基于微型計(jì)算機(jī)技術(shù)的發(fā)電廠電氣系統(tǒng)綜合自動(dòng)化的理想應(yīng)用程序,并給出了具體實(shí)現(xiàn)方案 2 發(fā)電廠電氣系統(tǒng)的現(xiàn)狀 電氣系統(tǒng)自動(dòng)化的進(jìn)步是建立在綜合自動(dòng)化和現(xiàn)場(chǎng)總線或以太網(wǎng)絡(luò)工藝學(xué)基礎(chǔ)之上的 。 lowersystem devices. Electrical devices have high reliability and swift action time. The technology level of individual electrical device is high. Presently, 16 or 32 bit singlechip scale programmable logic chip are used to build embedded system. Technologies of AC sampling and digital signal process are also widely DCS is widely used in power plants, and it fulfills basic operation and control functions. DCS concerns boiler system meanwhile little on Traditionally, control and signal exchange between DCS and electrical system is through this connection mode needs manycables, and the cost is high. Besides, the information It is electric operation management or achieve deep application of Since DCS is the most important system in power 3 Feasibility Analysis of Electrical System Integrated Automation The improvement of electrical system automation is based on integrated automation and field bus or industrial Ether technology. Microputer9based protection and automation devices are widely used in power plant electrical system. The measure, logic judge, action, record and man9 machine interface function can be done by software. Moreover, all these devices have munication interface, they can exchange information with master system or with each other through field bus. Fieldbus technology has been widely used in industry and electric power field , and it has been paid more and more attention. The technology in munication rate , munication distance and anti jamming capability has been improved. Many sorts of standards have been formed, such as Profibus advocated by Siemens, FF by ABB, CAN originated from au
