21世紀(jì)初，全球經(jīng)濟的發(fā)展使能源消耗總量創(chuàng)下了又一新高，對電的需求遠(yuǎn)遠(yuǎn)超出了對原始能量的需求總和，水利發(fā)電，將以其無可比擬的生態(tài)和環(huán)境優(yōu)勢在將來的能源供應(yīng)中起重要的作用。就這點來說，自動化系統(tǒng)是水電站水電系統(tǒng)的操作和維護(hù)進(jìn)行優(yōu)化的一個關(guān)鍵因素。
　　Andritz　AG公司是水利設(shè)備先驅(qū)制造商之一。120多年來，公司一直致力于水輪機的開發(fā)、設(shè)計和制造，如今，已成為水電系統(tǒng)的一個全面供應(yīng)商?！翱蛻魝兿Ｍ麅H從一個供應(yīng)處獲取項目執(zhí)行的所有服務(wù)，將接口數(shù)量最小化，并且由一個項目經(jīng)理負(fù)責(zé)整個項目?！?Andritz水利設(shè)備部門電氣及自動化部經(jīng)理Armin Martinz作了以上解釋。Andritz除了提供Kaplan,Francis, Pelton和小型渦輪機外，還提供完整的電力和過程控制設(shè)備。
　　在歐洲，水利發(fā)電廠的主要工作集中在更新和維護(hù)。相對來說，中國在新建水電廠方面有很大的潛力，而且也會在新系統(tǒng)上投入較大的資金。
　　數(shù)字渦輪過程控制系統(tǒng)的開發(fā)
　　Andritz過程控制設(shè)備其中有一部分是渦輪控制系統(tǒng)，由貝加萊公司設(shè)計并開發(fā)。貝加萊2005控制器和APROL過程控制系統(tǒng)的良好性能一直得到精湛的演繹。第一個在奧地利使用的系統(tǒng)的兩年無故障運行就是最好的證明。
　　在數(shù)字渦輪過程控制系統(tǒng)的開發(fā)過程中，在供應(yīng)商方面有很多公司可以選擇，因為已經(jīng)對貝加萊產(chǎn)品有了良好的應(yīng)用經(jīng)驗，Andritz 理所當(dāng)然也將貝加萊列入了考慮的名單中。Andritz所需要的供應(yīng)商除了要能提供適用于水電系統(tǒng)的整套控制產(chǎn)品，還包括過程控制硬件。產(chǎn)品除了要滿足諸如模塊化，電磁兼容(EMC)等一些基本要求以外，圖形化用戶界面、可確定性多任務(wù)以及簡便的遠(yuǎn)程控制方案也是必要的部分。另外，系統(tǒng)必須兼容C語言源代碼，這樣，已有的技術(shù)才能繼續(xù)使用，此外，還必須具備自動生成內(nèi)部文檔的功能，來創(chuàng)建詳細(xì)準(zhǔn)確的編程文檔?！白钪饕囊笫怯媒?jīng)濟的方案完成復(fù)雜的控制任務(wù)?！盡artinz在解釋為何選擇貝加萊時作如是回答。
　作為Andritz 的2005自動化系列產(chǎn)品的一部分，在ASC 2005控制站中可根據(jù)水流系統(tǒng)完成對所有機器及傳動裝置的自動無人化操作，例如，當(dāng)水電站儲備水量過大時，一旦發(fā)生洪水就會造成巨大損失，因此，這時候就要降低水位，保證大水量降臨時不會對下游產(chǎn)生災(zāi)害性的沖擊力。
　　Andritz自動化產(chǎn)品包括：ATC2005渦輪控制系統(tǒng)，機械渦輪和發(fā)電機保護(hù)，過程控制系統(tǒng)，貝加萊2005自動化系統(tǒng)以及ASC2005，所有這些保證了整個工廠的性能特點能根據(jù)實際需要作調(diào)整。2005自動化系統(tǒng)維持整個水電廠及上游流水在無干擾時處于正常狀態(tài)，在干擾發(fā)生時也能回復(fù)至安全操作狀態(tài)中。同樣來自貝加萊的2005控制系統(tǒng)和APROL過程控制系統(tǒng)針對苛刻的質(zhì)量要求完成所有的開環(huán)和閉環(huán)控制任務(wù)。
　　我們大多數(shù)人都遇到過在暴雨中突然斷電的情況，渦輪控制器的作用就是防止這種情況的發(fā)生，性能較差的渦輪控制器因其頻率不被支持，可能會產(chǎn)生電源不穩(wěn)，對個人財產(chǎn)帶來損失，也對企業(yè)管理工廠造成麻煩。同時高昂的維護(hù)費用以及隨之帶來的低劣的控制性能以及長期的不穩(wěn)定加速了磨損的過程并帶來了更多的污染問題。
