2098-DSD-010-SE現(xiàn)貨 in stock! 歡迎來(lái)電咨詢~！！

加拿大多倫多皮爾森國(guó)際機(jī)場(chǎng)以及加拿大東部和美國(guó)八個(gè)州共計(jì)百萬(wàn)人口，遭遇了嚴(yán)重的停電。這場(chǎng)災(zāi)難性事故警示我 們，機(jī)場(chǎng)需要獨(dú)立可靠的供電系統(tǒng)。該系統(tǒng)不僅要絕對(duì)保證全天候的可靠性，其經(jīng)濟(jì)性也是需要仔細(xì)考慮的。
　　熱電廠的設(shè)計(jì)采用一對(duì)GE LM6000PD航改氣輪機(jī)，每臺(tái)可輸出42MW，滿足了可靠性和成本的要求。渦輪機(jī)產(chǎn)生的氣體通過(guò)蒸汽 發(fā)動(dòng)機(jī)使第三個(gè)蒸汽驅(qū)動(dòng)發(fā)動(dòng)機(jī)運(yùn)行，輸出33MW。電廠剩余的熱量用于航站樓的制熱/制冷。該設(shè)計(jì)十分注重經(jīng)濟(jì)效益，產(chǎn)生的 多余電力可以出售給安大略湖電網(wǎng)。在詳細(xì)評(píng)估各供應(yīng)商的系統(tǒng)可靠性后，最終選擇了橫河電機(jī)CENTUM CS 3000控制系統(tǒng)。
　　“包括Cogen電廠在內(nèi)，我們對(duì)橫河電機(jī)控制系統(tǒng)的可靠性非常滿意�！贝蠖鄠惗鄼C(jī)場(chǎng)管理局(以下簡(jiǎn)稱GTAA)*1公共事業(yè)部高級(jí) 經(jīng)理Henry Oberhauser先生說(shuō)道。“這個(gè)可靠系統(tǒng)發(fā)生的唯一一次運(yùn)行中斷是由于分承包商提供的次標(biāo)準(zhǔn)的工藝用水引起的。我 們切實(shí)感受到了橫河電機(jī)的‘7個(gè)9’的可靠性，即40年停車時(shí)間少于一分鐘。”
　　*1 GTAA負(fù)責(zé)皮爾森機(jī)場(chǎng)的運(yùn)營(yíng)，在三個(gè)航站樓中，共有65家航空公司、82個(gè)登機(jī)口。第四航站樓正在設(shè)計(jì)中。機(jī)場(chǎng)年收入為140億美元，其中 稅收收入28億美元，同時(shí)提供135,000個(gè)工作崗位。它還擁有16,000個(gè)停車位。 *2 SNC-Lavalin是全球工程和建筑集團(tuán)公司的行業(yè)龍頭，已經(jīng)在加拿大及另外三十個(gè)國(guó)家設(shè)立了辦事處。其業(yè)務(wù)覆蓋超過(guò)100個(gè)國(guó)家。
　　電廠簡(jiǎn)介
　　該機(jī)場(chǎng)隸屬于GTAA，外部公司受雇負(fù)責(zé)電廠設(shè)計(jì)、建造以及運(yùn)行。為了滿足對(duì)電力和熱能的同步需求，同時(shí)獲得燃料(天然氣)， 熱電聯(lián)產(chǎn)系統(tǒng)是機(jī)場(chǎng)的最佳選擇。2001年初，GTAA曾為機(jī)場(chǎng)建立了一個(gè)中心公用電廠;隨著機(jī)場(chǎng)中各種設(shè)備的不斷增加，它逐 步取代了原有電廠。該電廠不僅為機(jī)場(chǎng)提供蒸汽取暖，還提供冷卻水為機(jī)場(chǎng)終端設(shè)備降溫。此次建立的新電廠可以提供所需要的 蒸汽，在使用熱電聯(lián)產(chǎn)系統(tǒng)產(chǎn)生的蒸汽時(shí)，還允許在備用模式下對(duì)電廠的蒸汽鍋爐進(jìn)行可選操作。該電廠于2003年建成。一年之 后，橫河電機(jī)控制系統(tǒng)投入運(yùn)行。 設(shè)計(jì)上一個(gè)有趣之處是采用了兩臺(tái)“直流蒸汽發(fā)生器”O(jiān)TSG，應(yīng)用了安大略省劍橋的創(chuàng)新蒸汽技術(shù)(IST)。與傳統(tǒng)設(shè)計(jì)相比，這 些機(jī)組具有以下一些優(yōu)點(diǎn)。它們不僅高效靈活，還可在三十分鐘之內(nèi)實(shí)現(xiàn)從冷啟動(dòng)到完全運(yùn)行。它們啟動(dòng)，運(yùn)行并完成干燥。無(wú) 需通過(guò)排氣管、分流閥系統(tǒng)和排氣管消聲器。從根本上說(shuō)，直流蒸汽發(fā)生器(OTSG)是熱交換器，由一系列管道組成，其中的鍋爐 水同時(shí)被加熱、蒸發(fā)和過(guò)熱。OTSG中回收的熱為蒸汽渦輪機(jī)提供所需的溫度和壓力。
　　橫河電機(jī)CENTUM CS 3000控制系統(tǒng) 整個(gè)Cogen電廠包括橫河電機(jī)監(jiān)視與控制系統(tǒng)和兩臺(tái)OTSG。OTSG的啟動(dòng)、運(yùn)行與停車是全自動(dòng)化的。其中復(fù)雜邏輯是由橫河電 機(jī)、IST與SNC-Lavalin*2的工程師們緊密合作而開發(fā)的。
　　控制室不僅可以顯示，它還是工程站。通過(guò)它可以訪問(wèn)技術(shù)圖紙和相關(guān)信息，如應(yīng)用代碼和標(biāo)準(zhǔn)以及其他工程信息等。系統(tǒng)仿真器不僅用于操作員培訓(xùn)，同時(shí)用于檢查和測(cè)試CS-3000邏輯中的變化。邏輯的修改可以通過(guò)該工程站完成。HART插件實(shí)現(xiàn)對(duì) HART I/O的診斷。而且，對(duì)該站的訪問(wèn)完全被保護(hù)，只有經(jīng)電廠授權(quán)的工程師才可以進(jìn)入。 每個(gè)月，協(xié)同工作的J.D.Edwards軟件包從橫河電機(jī)文件中選擇輸入項(xiàng)，打印出表格和圖示，提供維護(hù)指南。自從安裝了橫河電機(jī)的 系統(tǒng)后，沒有發(fā)生過(guò)重大維修。另外，CENTUM系統(tǒng)也同樣用于蒸汽監(jiān)控和水純度控制，以確保供給直流蒸汽發(fā)生器(OTSG)的蒸汽 的超高質(zhì)量。
