攀鋼1#高爐TRT工藝流程如圖1所示。高爐煤氣經(jīng)過(guò)除塵裝置后，在高爐煤氣減壓閥組前將高壓高爐煤氣引出，經(jīng)過(guò)TRT裝置的入口蝶閥、插板閥等閥門(mén)后進(jìn)入透平機(jī)入口，通過(guò)預(yù)流器使高爐煤氣轉(zhuǎn)成軸向進(jìn)入葉柵，高爐煤氣在靜葉柵和動(dòng)葉柵組成的流道中不斷地膨脹作功，壓力和溫度逐級(jí)降低，并轉(zhuǎn)化成動(dòng)能作用于工作輪上使之轉(zhuǎn)動(dòng)，工作輪通過(guò)聯(lián)軸器帶動(dòng)發(fā)電機(jī)一起轉(zhuǎn)動(dòng)而發(fā)電。減壓閥組在正常停機(jī)和緊急停機(jī)時(shí)，進(jìn)行高爐頂壓控制。

l  系統(tǒng)配置

攀鋼1#高爐TRT控制系統(tǒng)為杭州和利時(shí)自動(dòng)化有限公司的HOLLiAS DEH控制系統(tǒng)，采用上zui流行的現(xiàn)場(chǎng)總線(xiàn)ProfiBus-DP來(lái)連接主控單元和I/O模件，既滿(mǎn)足高速傳輸，又經(jīng)濟(jì)實(shí)用。HOLLiAS DEH控制系統(tǒng)由三大部分組成，電控部分、軟件部分和執(zhí)行機(jī)構(gòu)。電控部分包括一臺(tái)完成操作畫(huà)面設(shè)計(jì)、控制邏輯組態(tài)的計(jì)算機(jī)——工程師站；一臺(tái)完成操作監(jiān)視的計(jì)算機(jī)——操作員站，一個(gè)電子控制柜。電子控制柜由一對(duì)冗余主控單元組成的現(xiàn)場(chǎng)控制站，其中安裝了的測(cè)速模塊、伺服模塊以及DCS系統(tǒng)常用的DI、DO、AI、AO模塊，用于處理各種I/O信號(hào)。軟件部分包括系統(tǒng)軟件和應(yīng)用軟件兩種，系統(tǒng)軟件為由和利時(shí)公司開(kāi)發(fā)設(shè)計(jì)的MACSV系統(tǒng)，應(yīng)用軟件為該項(xiàng)目的控制邏輯組態(tài)及操作畫(huà)面，由云南陽(yáng)光基業(yè)軟件有限公司與和杭州和利時(shí)自動(dòng)化有限公司的工程技術(shù)人員設(shè)計(jì)完成。執(zhí)行機(jī)構(gòu)部分由成都發(fā)動(dòng)機(jī)（集團(tuán)）公司成套供貨，油動(dòng)機(jī)采用14MPa壓力油提供動(dòng)力。
