Kawasaki 30D60F-A228現(xiàn)貨 in stock! 歡迎來(lái)電咨詢~！！

21世紀(jì)初，全球經(jīng)濟(jì)的發(fā)展使能源消耗總量創(chuàng)下了又一新高，對(duì)電的需求遠(yuǎn)遠(yuǎn)超出了對(duì)原始能量的需求總和，水利發(fā)電，將以其無(wú)可比擬的生態(tài)和環(huán)境優(yōu)勢(shì)在將來(lái)的能源供應(yīng)中起重要的作用。就這點(diǎn)來(lái)說(shuō)，自動(dòng)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(gè)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(lái)，公司一直致力于水輪機(jī)的開(kāi)發(fā)、設(shè)計(jì)和制造，如今，已成為水電系統(tǒng)的一個(gè)全面供應(yīng)商。“客戶們希望僅從一個(gè)供應(yīng)處獲取項(xiàng)目執(zhí)行的所有服務(wù)，將接口數(shù)量最小化，并且由一個(gè)項(xiàng)目經(jīng)理負(fù)責(zé)整個(gè)項(xiàng)目。” Andritz水利設(shè)備部門電氣及自動(dòng)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(jī)外，還提供完整的電力和過(guò)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(duì)來(lái)說(shuō)，中國(guó)在新建水電廠方面有很大的潛力，而且也會(huì)在新系統(tǒng)上投入較大的資金。
　　數(shù)字渦輪過(guò)程控制系統(tǒng)的開(kāi)發(fā)
　　Andritz過(guò)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(jì)并開(kāi)發(fā)。貝加萊2005控制器和APROL過(guò)程控制系統(tǒng)的良好性能一直得到精湛的演繹。第一個(gè)在奧地利使用的系統(tǒng)的兩年無(wú)故障運(yùn)行就是最好的證明。
　　在數(shù)字渦輪過(guò)程控制系統(tǒng)的開(kāi)發(fā)過(guò)程中，在供應(yīng)商方面有很多公司可以選擇，因?yàn)橐呀?jīng)對(duì)貝加萊產(chǎn)品有了良好的應(yīng)用經(jīng)驗(yàn)，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(guò)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(jiǎn)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(yǔ)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(dòng)生成內(nèi)部文檔的功能，來(lái)創(chuàng)建詳細(xì)準(zhǔn)確的編程文檔。“最主要的要求是用經(jīng)濟(jì)的方案完成復(fù)雜的控制任務(wù)。”Martinz在解釋為何選擇貝加萊時(shí)作如是回答。
　作為Andritz 的2005自動(dòng)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(duì)所有機(jī)器及傳動(dòng)裝置的自動(dòng)無(wú)人化操作，例如，當(dāng)水電站儲(chǔ)備水量過(guò)大時(shí)，一旦發(fā)生洪水就會(huì)造成巨大損失，因此，這時(shí)候就要降低水位，保證大水量降臨時(shí)不會(huì)對(duì)下游產(chǎn)生災(zāi)害性的沖擊力。
　　Andritz自動(dòng)化產(chǎn)品包括：ATC2005渦輪控制系統(tǒng)，機(jī)械渦輪和發(fā)電機(jī)保護(hù)，過(guò)程控制系統(tǒng)，貝加萊2005自動(dòng)化系統(tǒng)以及ASC2005，所有這些保證了整個(gè)工廠的性能特點(diǎn)能根據(jù)實(shí)際需要作調(diào)整。2005自動(dòng)化系統(tǒng)維持整個(gè)水電廠及上游流水在無(wú)干擾時(shí)處于正常狀態(tài)，在干擾發(fā)生時(shí)也能回復(fù)至安全操作狀態(tài)中。同樣來(lái)自貝加萊的2005控制系統(tǒng)和APROL過(guò)程控制系統(tǒng)針對(duì)苛刻的質(zhì)量要求完成所有的開(kāi)環(huán)和閉環(huán)控制任務(wù)。
　　我們大多數(shù)人都遇到過(guò)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(huì)產(chǎn)生電源不穩(wěn)，對(duì)個(gè)人財(cái)產(chǎn)帶來(lái)?yè)p失，也對(duì)企業(yè)管理工廠造成麻煩。同時(shí)高昂的維護(hù)費(fèi)用以及隨之帶來(lái)的低劣的控制性能以及長(zhǎng)期的不穩(wěn)定加速了磨損的過(guò)程并帶來(lái)了更多的污染問(wèn)題。
