　　6月(yue)18日，華東電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)500千伏(fu)海(hai)寧(ning)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)順利帶(dai)電(dian)(dian)(dian)(dian)(dian)啟動，投(tou)入運行，這是國家電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)公司(si)第(di)一座基(ji)于IEC61850標準的(de)500千伏(fu)數字化(hua)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)。作為(wei)華東電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)今年(nian)迎峰度夏前投(tou)運的(de)重點工(gong)程，海(hai)寧(ning)變(bian)(bian)電(dian)(dian)(dian)(dian)(dian)站(zhan)可(ke)為(wei)國家重點工(gong)程秦山核(he)電(dian)(dian)(dian)(dian)(dian)站(zhan)擴建(jian)工(gong)程提(ti)供系統接(jie)入點，并提(ti)高浙(zhe)江(jiang)嘉興電(dian)(dian)(dian)(dian)(dian)網(wang)(wang)(wang)的(de)供電(dian)(dian)(dian)(dian)(dian)可(ke)靠性。

　　為推進堅強智能(neng)電(dian)網研(yan)究和建設，依托500千(qian)伏海寧(ning)變(bian)電(dian)站(zhan)工程(cheng)，華(hua)東電(dian)網有限(xian)公司積極開展科技(ji)創新，建設500千(qian)伏數(shu)字(zi)化(hua)變(bian)電(dian)站(zhan)示范工程(cheng)，為500千(qian)伏數(shu)字(zi)化(hua)變(bian)電(dian)站(zhan)的(de)推廣積累經驗。結合海寧(ning)變(bian)的(de)實際特(te)點，華(hua)東公司多次組織專家(jia)論證、確定(ding)工程(cheng)采用目前最完善的(de)變(bian)電(dian)站(zhan)通信網絡和系(xi)統標準——IEC61850系(xi)列標準為主(zhu)要(yao)原則的(de)數(shu)字(zi)化(hua)方案。

　　根據國家電(dian)網公(gong)司(si)有關(guan)部署，華東公(gong)司(si)在隨后新建的(de)500千伏蘇州(zhou)東變(bian)(bian)電(dian)站工(gong)程中顯著提升(sheng)了(le)數字化(hua)(hua)變(bian)(bian)電(dian)站的(de)實施比例，積極推廣示范工(gong)程成果，開展(zhan)數字化(hua)(hua)變(bian)(bian)電(dian)站標準化(hua)(hua)建設研究。新建工(gong)程投(tou)運后，將有力支撐(cheng)未來的(de)堅強(qiang)智能電(dian)網建設。

　　海(hai)寧變由華東公司投資建設(she)(she)(she)，本(ben)期(qi)規(gui)模(mo)為(wei)2組100萬(wan)千(qian)伏(fu)安主變壓器，500千(qian)伏(fu)出線3回(hui)(hui)，220千(qian)伏(fu)出線9回(hui)(hui)。工程建設(she)(she)(she)過(guo)程中，華東公司認(ren)真貫徹“兩型一化(hua)”建設(she)(she)(she)要求。全站(zhan)圍(wei)墻內(nei)占地(di)3.21公頃，僅為(wei)同(tong)等規(gui)模(mo)敞開(kai)式設(she)(she)(she)備變電站(zhan)的一半。
