船舶岸電供電也成為大鏟灣踐行環(huán)保承諾的舉措。“但是作為一門新的工藝技術(shù)，國內(nèi)岸電技術(shù)的應(yīng)用案例并不多，技術(shù)解決方案本身沒有太多經(jīng)驗可以參考?！标愜娨徽Z道出大鏟灣上馬岸電項目之初大的挑戰(zhàn)，“我們要尋找高品質(zhì)、高性價比，能滿足自身港口特定需求的岸電解決方案?！?br />
作為岸電解決方案的核心技術(shù)，西門子的岸電變頻電源設(shè)備使陳軍的愿望變成了現(xiàn)實。

西門子專注于船舶電氣和自動化技術(shù)已有百年歷史，相比其他競爭對手，西門子大型傳動部開發(fā)的專用于船舶岸電供電系統(tǒng)的岸電專用變頻電源在并船切換、邏輯控制等關(guān)鍵領(lǐng)域表現(xiàn)突出，而且具備工業(yè)級的產(chǎn)品品質(zhì)，完全能夠滿足大鏟灣岸電工程的訴求。

作為此次主體岸電系統(tǒng)設(shè)備供貨方，西門子充分考慮大鏟灣碼頭?？看暗拇图霸O(shè)計靠泊噸位，確定大鏟灣碼頭岸電的供電容量為5MVA，并為用戶提供2套 2.5MVA 的集裝箱式岸電系統(tǒng)設(shè)備，整體覆蓋 4 個泊位，既可實現(xiàn)單獨使用，亦可并聯(lián)實現(xiàn)高 5MVA 的大容量、穩(wěn)定電源給進港船只。而且，兩個相同2.5MVA容量的岸電系統(tǒng)所需備品備件相同，更加節(jié)省成本。

西門子岸電變頻電源設(shè)備的優(yōu)異性還體現(xiàn)在系統(tǒng)設(shè)計上。對大鏟灣碼頭而言，港區(qū)主要?？看肮╇婎l率為60Hz，主要靠泊船舶的供電電壓為6.6kV。西門子采用了“高-低-高”系統(tǒng)解決方案，即10kV-50Hz輸入，經(jīng)過降壓變壓器、低壓變頻電源及升壓變壓器，，變?yōu)?.6kV-60Hz輸出，通過變頻電源將岸上50Hz頻率轉(zhuǎn)化為60Hz輸出給船側(cè)，實現(xiàn)船電向岸電的在線平穩(wěn)切換。
