11月1日，南方電網直流輸電功率自動調整功能正式投入運行，西電東送通道±500千伏天廣、貴廣、貴廣二回直流功率調整正式由手動模式轉為自動模式，有效提高了電網的調控質量和調度運行人員的工作效率，對進一步提升電網安全運行水平具有重要意義。
±500千伏天(tian)廣(guang)、貴廣(guang)、貴廣(guang)二回(hui)直(zhi)(zhi)(zhi)流(liu)自(zi)(zi)(zi)(zi)投產以來，直(zhi)(zhi)(zhi)流(liu)功(gong)(gong)(gong)率(lv)(lv)(lv)調(diao)(diao)整(zheng)一直(zhi)(zhi)(zhi)采用手動模式(shi)(shi)。為了(le)更好地適(shi)應現代大電網(wang)(wang)運行(xing)需要(yao)，南方電網(wang)(wang)公司(si)對直(zhi)(zhi)(zhi)流(liu)功(gong)(gong)(gong)率(lv)(lv)(lv)采用自(zi)(zi)(zi)(zi)動定(ding)功(gong)(gong)(gong)率(lv)(lv)(lv)模式(shi)(shi)進(jin)(jin)行(xing)可行(xing)性(xing)研究(jiu)，開展直(zhi)(zhi)(zhi)流(liu)自(zi)(zi)(zi)(zi)動定(ding)功(gong)(gong)(gong)率(lv)(lv)(lv)的實時數(shu)字仿(fang)真（RTDS）、現場試(shi)驗，驗證了(le)直(zhi)(zhi)(zhi)流(liu)自(zi)(zi)(zi)(zi)動定(ding)功(gong)(gong)(gong)率(lv)(lv)(lv)模式(shi)(shi)的可行(xing)性(xing)及安全性(xing)，并于3月(yue)23日至5月(yue)23日進(jin)(jin)行(xing)直(zhi)(zhi)(zhi)流(liu)功(gong)(gong)(gong)率(lv)(lv)(lv)自(zi)(zi)(zi)(zi)動調(diao)(diao)整(zheng)試(shi)運行(xing)。試(shi)運行(xing)結果(guo)表明，直(zhi)(zhi)(zhi)流(liu)功(gong)(gong)(gong)率(lv)(lv)(lv)自(zi)(zi)(zi)(zi)動調(diao)(diao)整(zheng)功(gong)(gong)(gong)能(neng)具備正(zheng)式(shi)(shi)運行(xing)條件，于11月(yue)1日正(zheng)式(shi)(shi)投運。
