2022年國家(jia)電(dian)網(wang)公司三(san)大(da)(da)重點(dian)改造工程之一——三(san)峽近區電(dian)網(wang)優化工程日前(qian)順利投(tou)產。工程投(tou)運后，電(dian)網(wang)安全穩定水平(ping)進(jin)一步提(ti)升，能(neng)有(you)效(xiao)解決三(san)峽近區短路(lu)電(dian)流水平(ping)偏高、電(dian)磁(ci)環網(wang)潮(chao)流穿越、電(dian)力(li)疏散(san)能(neng)力(li)不足等問題。同時，豐(feng)水期恩施(shi)地區電(dian)力(li)外送能(neng)力(li)最大(da)(da)提(ti)升80萬(wan)千瓦(wa)，湖北(bei)西(xi)電(dian)東送通道能(neng)力(li)最大(da)(da)提(ti)升95萬(wan)千瓦(wa)，鄂西(xi)豐(feng)富的清潔能(neng)源消納力(li)度將進(jin)一步加大(da)(da)，有(you)力(li)支撐區域(yu)雙(shuang)碳目標的落實。

三(san)峽(xia)近區電網伴隨(sui)著世界規(gui)模最大的水電站——三(san)峽(xia)水電廠的興(xing)建(jian)而逐步成型(xing)，隨(sui)著渝鄂直流背(bei)靠背(bei)工(gong)程的投產(chan)，三(san)峽(xia)近區電網電力疏(shu)散壓力陡(dou)增。

國(guo)網華中分部(bu)(bu)于(yu)2017年研究提出三峽(xia)近(jin)區電網優(you)化方案(an)，并最終在國(guo)家(jia)電網公(gong)司和湖北省能源主管部(bu)(bu)門幫助支持下，將該(gai)工(gong)程方案(an)納入(ru)國(guo)家(jia)“十三五(wu)”電力(li)規劃。

三峽(xia)近區電(dian)(dian)(dian)網(wang)優(you)化(hua)工(gong)(gong)(gong)(gong)程項目涉(she)及國家(jia)電(dian)(dian)(dian)網(wang)公司、國網(wang)華中分部和國網(wang)湖北電(dian)(dian)(dian)力三家(jia)投資單位，共有(you)6項500千伏(fu)項目（安福-江陵與宜(yi)都-興(xing)隆500千伏(fu)線(xian)路(lu)對調(diao)工(gong)(gong)(gong)(gong)程、葛洲壩-雙河雙回500千伏(fu)線(xian)路(lu)增容改造工(gong)(gong)(gong)(gong)程、漁峽(xia)-宜(yi)都改接朝陽500千伏(fu)線(xian)路(lu)工(gong)(gong)(gong)(gong)程、宜(yi)都-孱陵500千伏(fu)線(xian)路(lu)工(gong)(gong)(gong)(gong)程、孱陵500千伏(fu)變電(dian)(dian)(dian)站擴建(jian)工(gong)(gong)(gong)(gong)程、安福500千伏(fu)變電(dian)(dian)(dian)站擴建(jian)工(gong)(gong)(gong)(gong)程）。工(gong)(gong)(gong)(gong)程具有(you)投資主體多、停電(dian)(dian)(dian)協(xie)調(diao)難(nan)、建(jian)設環境復雜等三大顯著特點。

為保(bao)障(zhang)工程順(shun)利實施，國網華中分(fen)部始(shi)終把確保(bao)大電網安全放(fang)在首位，充(chong)分(fen)發揮區(qu)域協調優勢和分(fen)部平臺作(zuo)用，創(chuang)新體(ti)制(zhi)機(ji)制(zhi)，多(duo)維度、全方位、精細化、全過程確保(bao)三(san)峽近區(qu)優化工程順(shun)利投產。
