二次再熱技術(shù)自動化控制的成功應(yīng)用，誕生出了全球效率最高的火電機(jī)組。而這項高精尖的技術(shù)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(jī)組(國電泰州電廠一期兩臺機(jī)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(jī)組，是當(dāng)今世界上發(fā)電效率最高、供電煤耗最低、環(huán)保指標(biāo)最優(yōu)的火電機(jī)組，代表了目前火力發(fā)電領(lǐng)域的最先進(jìn)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(biāo)最優(yōu)的火電機(jī)組的首要功臣，非二次再熱技術(shù)莫屬。那么，讓二次再熱技術(shù)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(shù)有限公司研發(fā)的，針對燃煤火電機(jī)組二次再熱技術(shù)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(jī)組的高效運行這套完全自主知識產(chǎn)權(quán)、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(shù)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(jì)的60年代。但是國外在二次再熱的利用方面單機(jī)最大裝機(jī)容量大約只有70萬千瓦。百萬千瓦火電機(jī)組的二次再熱是中國首創(chuàng)?！倍卧贌峒夹g(shù)主要是通過在常規(guī)一次再熱機(jī)組基礎(chǔ)上增加一級再熱器(鍋爐)和增加超高壓缸(汽機(jī))，進(jìn)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(jī)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(shè)備需要重新設(shè)計制造，設(shè)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(jī)組是目前世界上結(jié)構(gòu)最復(fù)雜的燃煤機(jī)組。
　　如此大規(guī)模和復(fù)雜的對象，對火電廠的控制系統(tǒng)提出了更高的要求?！白铋_始，我們對于讓北京國電智深控制技術(shù)有限公司來開發(fā)這一套系統(tǒng)，是存在一定的疑惑的。”國電泰州發(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(dāng)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(wù)合同，承擔(dān)了該電廠DCS與仿真系統(tǒng)研發(fā)制造供貨和工程應(yīng)用服務(wù)。
　　國電泰州電廠二期百萬千瓦超超臨界機(jī)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(jī)組關(guān)鍵技術(shù)研究與工程應(yīng)用”中，課題“二次再熱1000MW超超臨界機(jī)組關(guān)鍵技術(shù)工程示范”的依托示范工程。這是世界上首次在百萬千瓦機(jī)組上采用超超臨界、二次再熱技術(shù)，是國家燃煤發(fā)電節(jié)能減排示范項目。
