style="text-indent:25px">柴油發(fā)電機(jī)組備用電源可以替代電源的使用：替代電源的作用是彌補(bǔ)網(wǎng)電供應(yīng)之不足。這可能有兩種情況，一是網(wǎng)電價(jià)格過高，從節(jié)約成本的角度選擇柴油發(fā)電機(jī)作為替代電源;另一是在網(wǎng)電供應(yīng)不足的情況下，網(wǎng)電使用受到限制，供電部門不得已到處拉閘限電，這時(shí)，用電單位為了正常地生產(chǎn)和工作，就需要替代電源加以救濟(jì)。柴油發(fā)電機(jī)組備用電源可以用于消防電源：消防用發(fā)電機(jī)組主要是為了樓宇消防設(shè)備而配備的電源，一旦火災(zāi)等情況發(fā)生時(shí)，市電被切斷，發(fā)電機(jī)組成為消防設(shè)備的動(dòng)力來源，隨著消防法的遍極，國內(nèi)地產(chǎn)消防電源將會有巨大潛力發(fā)展的一個(gè)非常龐大的市場。常州備用電源控制有時(shí)備用電源需要手工啟動(dòng)，從而保證用電單位和個(gè)人能夠正常用電。</p><div

style="text-indent:25px">隨著科學(xué)技術(shù)的發(fā)展，一些電力用戶和用電設(shè)備，對電力供應(yīng)可靠性的要求越來越高。醫(yī)院、數(shù)據(jù)中心、通訊樞紐等一些重要用戶為了保證供電的可靠性，在它們的供電系統(tǒng)中，除了有雙電源供電外，其內(nèi)部另外設(shè)置了備用發(fā)電機(jī)，甚至有的還設(shè)置了不停電電源。以保證在緊急情況下給一些重要的場所和設(shè)備不間斷的供電。這些備用發(fā)電機(jī)組，只有電力系統(tǒng)故障，供電的兩個(gè)電源都同時(shí)停電時(shí)，才緊急啟動(dòng)發(fā)電。近幾年來我國的輸變電技術(shù)和設(shè)備都有了很大的發(fā)展，極大地提高了供電的可靠性，兩個(gè)電源同時(shí)故障的幾率很小。所以備用發(fā)電機(jī)啟動(dòng)的機(jī)會也越來越少。有的一年甚至幾年都不用一次。盡管如此，為了在緊急關(guān)頭有電可用，一些重要的用戶還是要花上幾十萬甚至幾百萬元，去購置備用發(fā)電機(jī)，放在那里以備不時(shí)之需。雖然這些發(fā)電機(jī)平時(shí)是不動(dòng)的，但是為了在緊急時(shí)能開得起來，發(fā)的出電，平時(shí)還要花費(fèi)許多的人力物力去精心維護(hù)保養(yǎng)。</p><p style="text-indent:25px">備用電源和應(yīng)急電源主要區(qū)別在于：一、一般來說，備用電源是相對于主電源來命名的，而且備用電源**于主電源，不是一個(gè)系統(tǒng)的電源，如果遇到主電源消失，也就是遇到停電時(shí)，備用電源就會自動(dòng)啟用，有時(shí)備用電源需要手工啟動(dòng)，從而保證用電單位和個(gè)人能夠正常用電。二、應(yīng)急電源是**于主電源和備用電源以外，也就是說不與外部電網(wǎng)聯(lián)系在一起，當(dāng)主電源和備用電源都不能正常供電時(shí)，應(yīng)急電源就會利用起來，保證正常用電。三、應(yīng)急電源的電會輸送到應(yīng)急供電系統(tǒng)，包括開關(guān)柜等。四、應(yīng)急電源一般情況下是停運(yùn)的，應(yīng)急電源可以在主電源和備用電源停電數(shù)秒內(nèi)啟動(dòng)使用，可以采用直流逆變電源，也可以快速啟動(dòng)柴油發(fā)電機(jī)組。備用電源和應(yīng)急電源共同點(diǎn)：二者都可以在主要電源出現(xiàn)故障時(shí)啟動(dòng)，向外發(fā)電，帶動(dòng)用電設(shè)備正常工作。備用電源和應(yīng)急電源都可以采用發(fā)電機(jī)組。對于一些居民區(qū)、酒店、醫(yī)院、超市、數(shù)據(jù)中心、養(yǎng)殖企業(yè)、化工企業(yè)等配備備用電源或者應(yīng)急電源是十分有必要的。現(xiàn)在，很多場合對供電的連續(xù)性要求很高，這類場合不但要求提供足夠的備用電源。</p><div
