6月(yue)10日，國(guo)家(jia)電(dian)(dian)網公司(si)組織專(zhuan)家(jia)，啟動了西北750千(qian)(qian)(qian)伏電(dian)(dian)網安(an)全(quan)專(zhuan)項評估，系統(tong)地梳理在(zai)運(yun)(yun)、在(zai)建和(he)規劃(hua)(hua)750千(qian)(qian)(qian)伏電(dian)(dian)網存在(zai)的安(an)全(quan)問題和(he)風險，全(quan)面加強750千(qian)(qian)(qian)伏電(dian)(dian)網規劃(hua)(hua)設(she)(she)計、設(she)(she)備選(xuan)型、安(an)裝調試、運(yun)(yun)行控制(zhi)、設(she)(she)備運(yun)(yun)維等(deng)工作，確保750千(qian)(qian)(qian)伏電(dian)(dian)網安(an)全(quan)穩定(ding)運(yun)(yun)行。
750千(qian)(qian)伏電(dian)(dian)網(wang)是西北(bei)電(dian)(dian)網(wang)骨干(gan)網(wang)架。750千(qian)(qian)伏輸電(dian)(dian)示范工程投(tou)運后，750千(qian)(qian)伏電(dian)(dian)網(wang)建(jian)設不斷加(jia)快，目前已累計(ji)投(tou)產(chan)10站(zhan)14線(xian)，總(zong)容量870萬千(qian)(qian)伏安(an)，線(xian)路2065千(qian)(qian)米。750千(qian)(qian)伏電(dian)(dian)網(wang)覆(fu)蓋(gai)陜、甘、青、寧(ning)四省（自治區），跨省輸電(dian)(dian)能力大幅提升。現有在建(jian)750千(qian)(qian)伏變(bian)電(dian)(dian)站(zhan)10座、線(xian)路19條(tiao)。
當前(qian)，西北750千(qian)(qian)伏(fu)(fu)電(dian)網(wang)(wang)全(quan)面(mian)快速發(fa)展，同(tong)時(shi)處在(zai)重要(yao)的轉型(xing)期(qi)。750千(qian)(qian)伏(fu)(fu)骨干網(wang)(wang)架成網(wang)(wang)初期(qi)，面(mian)臨(lin)著與330千(qian)(qian)伏(fu)(fu)電(dian)網(wang)(wang)協調過渡、電(dian)網(wang)(wang)運(yun)(yun)行(xing)控(kong)制、主設備質量(liang)風險控(kong)制和運(yun)(yun)行(xing)維護(hu)管控(kong)等問題(ti)。國家電(dian)網(wang)(wang)高度重視750千(qian)(qian)伏(fu)(fu)電(dian)網(wang)(wang)的安(an)全(quan)穩定運(yun)(yun)行(xing)工(gong)(gong)作(zuo)。西北電(dian)網(wang)(wang)有限公(gong)司、五(wu)省（自治(zhi)區(qu)）電(dian)力(li)公(gong)司按(an)照有關指示精神，周密部署，積極落實，依據《國家電(dian)網(wang)(wang)公(gong)司西北750千(qian)(qian)伏(fu)(fu)電(dian)網(wang)(wang)安(an)全(quan)評估(gu)框架》及時(shi)制定安(an)全(quan)評估(gu)細則，做好自查工(gong)(gong)作(zuo)。自評估(gu)報告(gao)已于5月(yue)底完成，6月(yue)1日(ri)起接(jie)受專家預評。
據(ju)悉，本次評估(gu)工作有(you)規劃運(yun)行、生產管理等兩個專家組參與(yu)，將(jiang)于14日(ri)結束。專家們(men)將(jiang)進一步(bu)聽取(qu)各單位安(an)全(quan)(quan)專項自查(cha)中發(fa)現的(de)問題和應(ying)對措施(shi)，查(cha)找需要改進和完(wan)善的(de)部分，進一步(bu)完(wan)善安(an)全(quan)(quan)評估(gu)報告。國家電網將(jiang)根據(ju)評估(gu)情況制定切實(shi)可行的(de)《西北750千伏電網安(an)全(quan)(quan)穩定工作實(shi)施(shi)方案》。
