二次再熱技術自動化控制的成功應用，誕生出了全球效率最高的火電機組。而這項高精尖的技術又是如何誕生的
　　6月的泰州已經(jīng)有了夏日的悶熱感。走在長江邊的國電泰州電廠內(nèi)，不一會就會熱的滿身大汗。
　　這里是國內(nèi)最早一批百萬千瓦超超臨界火電機組(國電泰州電廠一期兩臺機組)的所在地。而如今，國電泰州電廠二期、世界首臺百萬千瓦超超臨界二次再熱燃煤發(fā)電機組，是當今世界上發(fā)電效率最高、供電煤耗最低、環(huán)保指標最優(yōu)的火電機組，代表了目前火力發(fā)電領域的最先進水平。
　　論起國電泰州電廠二期能夠成為世界上發(fā)電效率最高、供電煤耗最低、環(huán)保指標最優(yōu)的火電機組的首要功臣，非二次再熱技術莫屬。那么，讓二次再熱技術能夠安全高效運轉(zhuǎn)的首要功臣，則是北京國電智深控制技術有限公司研發(fā)的，針對燃煤火電機組二次再熱技術的DCS系統(tǒng)。
　　DCS系統(tǒng)如何保障了國電泰州電廠二期、世界首臺百萬千萬超超臨界二次再熱燃煤發(fā)電機組的高效運行這套完全自主知識產(chǎn)權、打破壟斷的系統(tǒng)，又是經(jīng)歷了哪些困難才順利誕生的
　　艱難誕生
　　“二次再熱是煤炭清潔高效利用的一個有效途徑。”北京國電智深控制技術有限公司副總經(jīng)理黃煥袍對記者說，“二次再熱在國外最早可以追溯到上世紀的60年代。但是國外在二次再熱的利用方面單機最大裝機容量大約只有70萬千瓦。百萬千瓦火電機組的二次再熱是中國首創(chuàng)?！倍卧贌峒夹g主要是通過在常規(guī)一次再熱機組基礎上增加一級再熱器(鍋爐)和增加超高壓缸(汽機)，進一步提高蒸汽參數(shù)(溫度和壓力)。這些參數(shù)提高之后，那么機組的燃煤效率、熱循環(huán)效率和發(fā)電效率就提高了。
　　這就要求設備需要重新設計制造，設備流程也與之前有了較大的不同?？梢哉f，百萬千瓦二次再熱機組是目前世界上結(jié)構最復雜的燃煤機組。
　　如此大規(guī)模和復雜的對象，對火電廠的控制系統(tǒng)提出了更高的要求。“最開始，我們對于讓北京國電智深控制技術有限公司來開發(fā)這一套系統(tǒng)，是存在一定的疑惑的?！眹娞┲莅l(fā)電有限公司副總經(jīng)理張?zhí)K閩對《能源》雜志記者說，“我們當時傾向于讓國外有過二次再熱項目業(yè)績的公司來做。”
　　火電廠控制系統(tǒng)開發(fā)企業(yè)數(shù)量多、競爭激烈。除了外企之外，還有數(shù)量不少的國內(nèi)企業(yè)也參與了競爭。國電智深于2013年11月與國電泰州發(fā)電有限公司簽訂DCS與仿真供貨服務合同，承擔了該電廠DCS與仿真系統(tǒng)研發(fā)制造供貨和工程應用服務。
　　國電泰州電廠二期百萬千瓦超超臨界機組二次再熱項目是國家科技支撐計劃項目——“高效率低排放的超600℃百萬千瓦等級超超臨界機組關鍵技術研究與工程應用”中，課題“二次再熱1000MW超超臨界機組關鍵技術工程示范”的依托示范工程。這是世界上首次在百萬千瓦機組上采用超超臨界、二次再熱技術，是國家燃煤發(fā)電節(jié)能減排示范項目。
