近日，南(nan)方電(dian)網(wang)公(gong)司在云南(nan)昆明實施了國內(nei)首(shou)次10千伏高(gao)壓發(fa)電(dian)系統同期接入(ru)電(dian)網(wang)轉供(gong)負(fu)荷，標志著南(nan)方電(dian)網(wang)重點科技(ji)項目“配網(wang)不停電(dian)關鍵技(ji)術研究”取(qu)得重大(da)突(tu)破(po)，填(tian)補該技(ji)術領域(yu)的國內(nei)空白。
本次作(zuo)業(ye)在昆明呈(cheng)貢地區通(tong)過旁路帶電(dian)(dian)(dian)作(zuo)業(ye)的方(fang)式，將10千(qian)伏移(yi)(yi)(yi)動發(fa)(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)(xi)統通(tong)過自(zi)主(zhu)研(yan)發(fa)(fa)(fa)的移(yi)(yi)(yi)動斷路器(qi)同期(qi)接入10千(qian)伏配網。10千(qian)伏移(yi)(yi)(yi)動發(fa)(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)(xi)統并(bing)網運行(xing)后，可實(shi)(shi)現(xian)檢修區段線(xian)路與轉供區段線(xian)路的隔離(li)，最終將轉供區段線(xian)路無縫切換(huan)由(you)10千(qian)伏移(yi)(yi)(yi)動發(fa)(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)(xi)統供電(dian)(dian)(dian)。該作(zuo)業(ye)方(fang)法(fa)改變了以(yi)往移(yi)(yi)(yi)動發(fa)(fa)(fa)電(dian)(dian)(dian)系(xi)(xi)(xi)統轉供電(dian)(dian)(dian)時需先停電(dian)(dian)(dian)接入系(xi)(xi)(xi)統，再由(you)發(fa)(fa)(fa)電(dian)(dian)(dian)機(ji)組供電(dian)(dian)(dian)的現(xian)狀，真正實(shi)(shi)現(xian)了對(dui)(dui)用(yong)戶(hu)轉供電(dian)(dian)(dian)的無縫切換(huan)，對(dui)(dui)提高客(ke)戶(hu)供電(dian)(dian)(dian)可靠(kao)性、減少客(ke)戶(hu)停電(dian)(dian)(dian)時間，特別是保障對(dui)(dui)敏(min)感用(yong)戶(hu)的持續穩(wen)定可靠(kao)供電(dian)(dian)(dian)具有重要的現(xian)實(shi)(shi)意(yi)義(yi)和實(shi)(shi)用(yong)價值。
