6月(yue)18日，華東(dong)電(dian)(dian)(dian)(dian)網500千伏(fu)海寧(ning)變電(dian)(dian)(dian)(dian)站順利帶(dai)電(dian)(dian)(dian)(dian)啟動，投入(ru)運行，這是國家電(dian)(dian)(dian)(dian)網公司第一座基于(yu)IEC61850標準的(de)500千伏(fu)數字化變電(dian)(dian)(dian)(dian)站。作為華東(dong)電(dian)(dian)(dian)(dian)網今(jin)年(nian)迎峰度夏前投運的(de)重點(dian)工程(cheng)，海寧(ning)變電(dian)(dian)(dian)(dian)站可(ke)為國家重點(dian)工程(cheng)秦山核電(dian)(dian)(dian)(dian)站擴(kuo)建工程(cheng)提(ti)供系統接入(ru)點(dian)，并提(ti)高浙江(jiang)嘉興電(dian)(dian)(dian)(dian)網的(de)供電(dian)(dian)(dian)(dian)可(ke)靠性。
為推(tui)進堅強智能電(dian)網(wang)(wang)(wang)研究和(he)(he)建設(she)(she)，依托500千(qian)伏(fu)海(hai)寧變(bian)電(dian)站工程(cheng)，華東(dong)(dong)電(dian)網(wang)(wang)(wang)有限公司積極開展科技創新，建設(she)(she)500千(qian)伏(fu)數字化(hua)變(bian)電(dian)站示范工程(cheng)，為500千(qian)伏(fu)數字化(hua)變(bian)電(dian)站的(de)推(tui)廣(guang)積累經驗。結(jie)合海(hai)寧變(bian)的(de)實(shi)際特點，華東(dong)(dong)公司多(duo)次(ci)組織專家論(lun)證、確定工程(cheng)采用目前最完善的(de)變(bian)電(dian)站通信(xin)網(wang)(wang)(wang)絡(luo)和(he)(he)系(xi)統標準——IEC61850系(xi)列標準為主要原則的(de)數字化(hua)方案。
根(gen)據國家電(dian)(dian)網公(gong)司有(you)關部署，華東公(gong)司在(zai)隨后新建(jian)(jian)的(de)(de)(de)500千伏蘇州東變(bian)電(dian)(dian)站工(gong)程(cheng)中顯著提升(sheng)了數字化變(bian)電(dian)(dian)站的(de)(de)(de)實施(shi)比例，積極推廣示范工(gong)程(cheng)成(cheng)果，開展(zhan)數字化變(bian)電(dian)(dian)站標(biao)準化建(jian)(jian)設研究。新建(jian)(jian)工(gong)程(cheng)投運后，將有(you)力支(zhi)撐未(wei)來的(de)(de)(de)堅強(qiang)智能電(dian)(dian)網建(jian)(jian)設。
海寧變(bian)由華(hua)(hua)東公(gong)司投資建(jian)設(she)，本期規模為(wei)2組(zu)100萬千伏(fu)(fu)安主變(bian)壓器，500千伏(fu)(fu)出線(xian)3回，220千伏(fu)(fu)出線(xian)9回。工程建(jian)設(she)過程中，華(hua)(hua)東公(gong)司認(ren)真貫徹“兩型一化”建(jian)設(she)要求。全(quan)站(zhan)圍墻(qiang)內占地3.21公(gong)頃，僅為(wei)同(tong)等規模敞開式設(she)備(bei)變(bian)電站(zhan)的一半。
