從我國自主研發和生產的DCS成功應用于60萬千瓦、100萬千瓦超超臨界機組,到首臺最大容量60萬千瓦超臨界循環流化床機組DCS的突破,再到被稱為核電站“神經中樞”的核電站全數字化儀控系統實現自主研發,近年來我國DCS實現了跨越式發展。
20世紀末,DCS在國內燃煤機組上應用時,其監控功能覆蓋范圍還僅限DAS、MCS、FSSS和SCS四項。即使在2004年發布的Q/DG1-K401-2004《火力發電廠分散控制系統(DCS)技術規范書》中,DCS應用的主要功能子系統仍然還是以上四項。“但實際上近幾年DCS的應用范圍迅速擴展,除了一大批高參數、大容量、不同控制結構的燃煤火電機組(如浙江玉環電廠100萬千瓦機組)的各個控制子系統全面應用外,脫硫系統、脫硝系統、空冷系統、大型循環流化床(CFB)鍋爐等新工藝方面都成功應用。可以說只要工藝上能夠實現的系統,DCS都能實現對其進行可靠控制。”一位熱工行業的負責人曾表示。
有專家分析認為,目前隨著自動化控制技術的發展,火力發電系統的自動化程度也越來越高。在火電系統中DCS應用雖然說不是國內最早,但絕對是最廣泛的。在火電的發展過程中,隨著社會對電力資源需求越來越高,以往較為粗放式的發電已經行不通了,需要進更精細化的發電,以達到資源的最大利用率。而這種控制都需要靠自動化技術來實現,單純的人工是達不到這種效果的。作為國家基礎建設的重中之重,電力系統只能盡可能選用國產控制系統,來提高安全率。
“目前,主機控制和輔網控制采用DCS一體化的項目也愈來愈多。即在控制系統的高、精、尖上不斷突破,在控制的范圍上不斷擴大,且國產化市場占有率增加勢頭也較猛,特別是在老機組DCS改造方面。近期,我們也拿到了DCS改造項目,為后續老機組DCS改造的國產化開了個好頭。
