近日，南(nan)方電(dian)網公(gong)司在云南(nan)昆明實施了(le)國(guo)內(nei)首次(ci)10千伏高壓(ya)發電(dian)系統同期接入電(dian)網轉(zhuan)供負荷，標志著南(nan)方電(dian)網重(zhong)點科技項目“配(pei)網不停電(dian)關鍵技術(shu)研(yan)究”取得重(zhong)大突破，填補該(gai)技術(shu)領域的國(guo)內(nei)空白。
本次作(zuo)業(ye)(ye)在昆(kun)明呈貢地(di)區(qu)通(tong)過旁路帶(dai)電(dian)(dian)(dian)(dian)(dian)(dian)作(zuo)業(ye)(ye)的(de)方(fang)式，將10千(qian)伏(fu)(fu)移(yi)動發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)通(tong)過自主研(yan)發(fa)(fa)的(de)移(yi)動斷路器同(tong)期接(jie)入10千(qian)伏(fu)(fu)配網(wang)。10千(qian)伏(fu)(fu)移(yi)動發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)并網(wang)運行后，可(ke)(ke)實(shi)現檢修區(qu)段(duan)線路與(yu)轉供(gong)(gong)(gong)區(qu)段(duan)線路的(de)隔離，最(zui)終將轉供(gong)(gong)(gong)區(qu)段(duan)線路無縫(feng)切換由10千(qian)伏(fu)(fu)移(yi)動發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。該作(zuo)業(ye)(ye)方(fang)法改(gai)變(bian)了以往移(yi)動發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統(tong)轉供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)需先停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)接(jie)入系(xi)(xi)統(tong)，再由發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機(ji)組供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)現狀，真正實(shi)現了對(dui)用(yong)戶(hu)轉供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)無縫(feng)切換，對(dui)提(ti)高客戶(hu)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)可(ke)(ke)靠性(xing)、減少客戶(hu)停(ting)(ting)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)間，特別是保障對(dui)敏感(gan)用(yong)戶(hu)的(de)持續穩定可(ke)(ke)靠供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)具有重(zhong)要的(de)現實(shi)意(yi)義和實(shi)用(yong)價值(zhi)。
