近(jin)日，南方電(dian)(dian)網(wang)公司在云南昆(kun)明(ming)實施了國內首(shou)次10千伏(fu)高壓發電(dian)(dian)系統同期接(jie)入(ru)電(dian)(dian)網(wang)轉供負荷，標(biao)志(zhi)著南方電(dian)(dian)網(wang)重點科技(ji)項目“配網(wang)不停電(dian)(dian)關鍵技(ji)術(shu)研究(jiu)”取得(de)重大突破，填補該(gai)技(ji)術(shu)領域的(de)國內空白(bai)。
本次作(zuo)業在(zai)昆明呈貢地區(qu)通過(guo)旁路帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)作(zuo)業的(de)方(fang)式(shi)，將(jiang)10千(qian)伏(fu)移(yi)(yi)(yi)(yi)動發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統通過(guo)自主研發的(de)移(yi)(yi)(yi)(yi)動斷路器同期接(jie)入(ru)10千(qian)伏(fu)配網(wang)。10千(qian)伏(fu)移(yi)(yi)(yi)(yi)動發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統并網(wang)運(yun)行后，可(ke)實(shi)(shi)現(xian)檢修(xiu)區(qu)段(duan)線路與轉(zhuan)供(gong)區(qu)段(duan)線路的(de)隔離，最(zui)終將(jiang)轉(zhuan)供(gong)區(qu)段(duan)線路無(wu)縫(feng)切(qie)換(huan)由(you)10千(qian)伏(fu)移(yi)(yi)(yi)(yi)動發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。該作(zuo)業方(fang)法(fa)改(gai)變了以往移(yi)(yi)(yi)(yi)動發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統轉(zhuan)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時需先停電(dian)(dian)(dian)(dian)(dian)(dian)(dian)接(jie)入(ru)系統，再由(you)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機組供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)現(xian)狀，真正實(shi)(shi)現(xian)了對用戶(hu)(hu)轉(zhuan)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)無(wu)縫(feng)切(qie)換(huan)，對提(ti)高客戶(hu)(hu)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)可(ke)靠(kao)(kao)性、減少客戶(hu)(hu)停電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時間，特別是(shi)保障對敏感用戶(hu)(hu)的(de)持續穩定可(ke)靠(kao)(kao)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)具(ju)有重(zhong)要的(de)現(xian)實(shi)(shi)意義和實(shi)(shi)用價值。
