DEH系統介紹

華能岳陽電廠二期擴建工程(2×300MW)汽輪機是由哈爾濱汽輪機廠生產的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凝汽式汽輪機組。DCS系統采用PineControl系統，DEH為該系統的一個控制站。系統硬件采用進口的雙CPU、雙電源熱備PLC，組態(tài)軟件為PineControl系統的PineCAD組態(tài)軟件。

汽輪機數字式電液調節(jié)系統(DEH)硬件配置主要由上位計算機(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、機柜等組成。系統采用兩層網絡結構：第一層為管理層采用冗余100M工業(yè)以太網，負責上位機與控制站的通信；第二層為控制層采用Controller Link總線，負責控制站間的通信。當控制層網絡故障時，100M工業(yè)以太網作為控制層網絡的后備，能自動切到100M冗余工業(yè)以太網通信。

產品廣泛應用于：電力、石油、礦井提升、港口、供熱、燃氣、供水、污水處理、冶金、造紙、紡織、化工、水利等現代化工業(yè)領域！
