DEH系統(tǒng)介紹
華能岳陽(yáng)電廠二期擴(kuò)建工程(2×300MW)汽輪機(jī)是由哈爾濱汽輪機(jī)廠生產(chǎn)的N300-16.7/537/537型亞臨界、中間再熱、高中壓合缸、雙缸雙排汽單軸反動(dòng)凝汽式汽輪機(jī)組。DCS系統(tǒng)采用PineControl系統(tǒng)，DEH為該系統(tǒng)的一個(gè)控制站。系統(tǒng)硬件采用進(jìn)口的雙CPU、雙電源熱備PLC，組態(tài)軟件為PineControl系統(tǒng)的PineCAD組態(tài)軟件。
汽輪機(jī)數(shù)字式電液調(diào)節(jié)系統(tǒng)(DEH)硬件配置主要由上位計(jì)算機(jī)(工程師站、操作員站等與DCS共用)、邏輯處理單元CPU以及各種I/O卡件、機(jī)柜等組成。系統(tǒng)采用兩層網(wǎng)絡(luò)結(jié)構(gòu)：第一層為管理層采用冗余100M工業(yè)以太網(wǎng)，負(fù)責(zé)上位機(jī)與控制站的通信；第二層為控制層采用Controller Link總線(xiàn)，負(fù)責(zé)控制站間的通信。當(dāng)控制層網(wǎng)絡(luò)故障時(shí)，100M工業(yè)以太網(wǎng)作為控制層網(wǎng)絡(luò)的后備，能自動(dòng)切到100M冗余工業(yè)以太網(wǎng)通信。
產(chǎn)品廣泛應(yīng)用于：電力、石油、礦井提升、港口、供熱、燃?xì)?、供水、污水處理、冶金、造紙、紡織、化工、水利等現(xiàn)代化工業(yè)領(lǐng)域！
