DCS系統(tǒng)的供電系統(tǒng)是其運(yùn)行的基礎(chǔ)，電源負(fù)荷不要超過60%，以免電源高負(fù)荷運(yùn)行。同時(shí)要考慮用高品質(zhì)的電源，一般筆者采用UPS電源，采用兩臺(tái)UPS互為備用最好，一臺(tái)出現(xiàn)故障后備用機(jī)能夠無擾切換，提高電源的可靠性。UPS輸入電源不要采用電氣的同一母線，要根據(jù)電氣廠用接線取可靠性高的不同母線段電源，這樣保證電氣一段母線出現(xiàn)問題后不會(huì)影響DCS系統(tǒng)的電源。
? ??DCS電源系統(tǒng)(UPS、電源柜等)在現(xiàn)場(chǎng)安裝時(shí)要安裝在滿足無塵、無振動(dòng)、防腐等要求的電子設(shè)備間內(nèi)，同時(shí)安裝完畢通電前把電纜孔封堵，以防泄漏蒸汽從電纜孔進(jìn)入電源系統(tǒng)造成電源短路。在DCS電源上電后，要在UPS、電源柜等設(shè)備上掛“設(shè)備帶電運(yùn)行禁止操作”標(biāo)識(shí)牌，更不準(zhǔn)可以在DCS電源系統(tǒng)上接入與DCS系統(tǒng)無關(guān)的負(fù)載，如檢修電源、檢修照明、充電設(shè)備、空調(diào)等。
