由智光電(dian)(dian)氣承建的(de)秦皇島港高壓(ya)(ya)船(chuan)舶岸電(dian)(dian)系(xi)統在(zai)秦皇島709泊位成功為76000噸的(de)“神(shen)華(hua)801”輪順(shun)利接(jie)電(dian)(dian)，實(shi)現(xian)了一次性連船(chuan)成功，采用岸上高壓(ya)(ya)電(dian)(dian)源(yuan)直(zhi)接(jie)供電(dian)(dian)，經大功率(lv)電(dian)(dian)力(li)電(dian)(dian)子技術進行變(bian)換之后可直(zhi)接(jie)實(shi)現(xian)異頻雙高電(dian)(dian)壓(ya)(ya)（6.6kV及11kV）輸出，可適應不同船(chuan)舶電(dian)(dian)壓(ya)(ya)等級的(de)需要，中間回路(lu)無需采用降壓(ya)(ya)及升壓(ya)(ya)變(bian)壓(ya)(ya)器來實(shi)現(xian)電(dian)(dian)壓(ya)(ya)變(bian)換，轉換效率(lv)高。
