6月18日，華(hua)東電(dian)(dian)(dian)網500千(qian)(qian)伏(fu)海(hai)寧變電(dian)(dian)(dian)站(zhan)(zhan)順利(li)帶電(dian)(dian)(dian)啟動(dong)，投(tou)入(ru)運行，這是國家(jia)電(dian)(dian)(dian)網公司第(di)一座基于IEC61850標準的500千(qian)(qian)伏(fu)數字化變電(dian)(dian)(dian)站(zhan)(zhan)。作(zuo)為(wei)華(hua)東電(dian)(dian)(dian)網今年迎(ying)峰度夏前投(tou)運的重點工(gong)程，海(hai)寧變電(dian)(dian)(dian)站(zhan)(zhan)可(ke)為(wei)國家(jia)重點工(gong)程秦山核電(dian)(dian)(dian)站(zhan)(zhan)擴建工(gong)程提(ti)(ti)供(gong)系統接入(ru)點，并提(ti)(ti)高浙江(jiang)嘉興電(dian)(dian)(dian)網的供(gong)電(dian)(dian)(dian)可(ke)靠性。
為推進堅強智能電(dian)(dian)(dian)網研究和建(jian)設，依托500千(qian)伏(fu)(fu)海寧(ning)變電(dian)(dian)(dian)站(zhan)工程(cheng)，華(hua)東電(dian)(dian)(dian)網有限公司積極開展科技創新，建(jian)設500千(qian)伏(fu)(fu)數(shu)字化(hua)變電(dian)(dian)(dian)站(zhan)示范工程(cheng)，為500千(qian)伏(fu)(fu)數(shu)字化(hua)變電(dian)(dian)(dian)站(zhan)的(de)推廣積累經驗。結合海寧(ning)變的(de)實際特點(dian)，華(hua)東公司多(duo)次組(zu)織專(zhuan)家論證、確定工程(cheng)采用(yong)目前最完善的(de)變電(dian)(dian)(dian)站(zhan)通信網絡(luo)和系統標(biao)準——IEC61850系列標(biao)準為主要原則(ze)的(de)數(shu)字化(hua)方案(an)。
根(gen)據國家電(dian)(dian)網(wang)公司(si)有(you)(you)關(guan)部署，華東(dong)公司(si)在隨后新(xin)建的(de)500千(qian)伏蘇州東(dong)變(bian)電(dian)(dian)站工(gong)(gong)(gong)程(cheng)中顯著提升了(le)數字化(hua)變(bian)電(dian)(dian)站的(de)實(shi)施(shi)比例(li)，積(ji)極推廣示(shi)范工(gong)(gong)(gong)程(cheng)成果(guo)，開展數字化(hua)變(bian)電(dian)(dian)站標準(zhun)化(hua)建設研(yan)究。新(xin)建工(gong)(gong)(gong)程(cheng)投運后，將有(you)(you)力支撐(cheng)未來(lai)的(de)堅強(qiang)智能電(dian)(dian)網(wang)建設。
海寧變(bian)由華東公司投資建設，本期(qi)規模(mo)為2組100萬千(qian)伏(fu)(fu)安主變(bian)壓器(qi)，500千(qian)伏(fu)(fu)出線3回(hui)，220千(qian)伏(fu)(fu)出線9回(hui)。工程(cheng)建設過(guo)程(cheng)中，華東公司認真(zhen)貫徹“兩型(xing)一(yi)化”建設要求(qiu)。全站(zhan)圍墻內占地3.21公頃(qing)，僅為同等規模(mo)敞開式設備變(bian)電站(zhan)的一(yi)半。
