6月10日，國家電網(wang)公(gong)司組(zu)織專(zhuan)家，啟動了西(xi)北750千伏電網(wang)安(an)(an)(an)全(quan)專(zhuan)項評(ping)估(gu)，系統地(di)梳(shu)理在運、在建和(he)規劃750千伏電網(wang)存在的(de)安(an)(an)(an)全(quan)問(wen)題和(he)風(feng)險(xian)，全(quan)面加強750千伏電網(wang)規劃設(she)計、設(she)備選型、安(an)(an)(an)裝調試(shi)、運行(xing)控制、設(she)備運維等工作，確(que)保750千伏電網(wang)安(an)(an)(an)全(quan)穩(wen)定(ding)運行(xing)。
750千(qian)伏(fu)電(dian)(dian)網(wang)是(shi)西(xi)北電(dian)(dian)網(wang)骨(gu)干(gan)網(wang)架。750千(qian)伏(fu)輸電(dian)(dian)示(shi)范工(gong)程(cheng)投運(yun)后(hou)，750千(qian)伏(fu)電(dian)(dian)網(wang)建設不斷加(jia)快，目前已累計(ji)投產10站14線(xian)，總(zong)容量870萬千(qian)伏(fu)安，線(xian)路2065千(qian)米。750千(qian)伏(fu)電(dian)(dian)網(wang)覆蓋陜、甘、青、寧四(si)省(sheng)(sheng)（自治(zhi)區），跨(kua)省(sheng)(sheng)輸電(dian)(dian)能力大幅提(ti)升。現有在建750千(qian)伏(fu)變電(dian)(dian)站10座、線(xian)路19條。
當前，西北(bei)750千(qian)(qian)伏電(dian)(dian)(dian)(dian)網全面(mian)快速發(fa)展，同(tong)時(shi)處(chu)在重要的(de)轉型期(qi)。750千(qian)(qian)伏骨干(gan)網架(jia)成網初期(qi)，面(mian)臨著與(yu)330千(qian)(qian)伏電(dian)(dian)(dian)(dian)網協調過渡、電(dian)(dian)(dian)(dian)網運行(xing)控(kong)制(zhi)、主設備(bei)質量風險控(kong)制(zhi)和運行(xing)維(wei)護(hu)管控(kong)等問題。國(guo)家電(dian)(dian)(dian)(dian)網高度重視750千(qian)(qian)伏電(dian)(dian)(dian)(dian)網的(de)安全穩定運行(xing)工作(zuo)。西北(bei)電(dian)(dian)(dian)(dian)網有限公(gong)司(si)、五省（自(zi)治(zhi)區）電(dian)(dian)(dian)(dian)力公(gong)司(si)按照有關指示精神，周密部(bu)署，積(ji)極落實，依據《國(guo)家電(dian)(dian)(dian)(dian)網公(gong)司(si)西北(bei)750千(qian)(qian)伏電(dian)(dian)(dian)(dian)網安全評估框架(jia)》及(ji)時(shi)制(zhi)定安全評估細(xi)則(ze)，做好(hao)自(zi)查工作(zuo)。自(zi)評估報(bao)告(gao)已于5月(yue)底完成，6月(yue)1日起接(jie)受專(zhuan)家預評。
據悉，本(ben)次評(ping)估(gu)工作有規劃運行、生(sheng)產管理等兩個專家組參(can)與，將(jiang)于14日結束。專家們將(jiang)進(jin)一步聽取(qu)各(ge)單位安(an)全(quan)專項自查中(zhong)發現的問題和(he)應對措(cuo)施(shi)，查找需(xu)要改進(jin)和(he)完善(shan)的部分，進(jin)一步完善(shan)安(an)全(quan)評(ping)估(gu)報告。國家電網(wang)將(jiang)根據評(ping)估(gu)情況(kuang)制(zhi)定(ding)切實(shi)可行的《西北750千伏(fu)電網(wang)安(an)全(quan)穩(wen)定(ding)工作實(shi)施(shi)方案》。
