6月10日，國家(jia)電(dian)(dian)(dian)網(wang)公司組織專(zhuan)家(jia)，啟(qi)動了西北750千伏(fu)(fu)電(dian)(dian)(dian)網(wang)安全(quan)專(zhuan)項評(ping)估，系統(tong)地(di)梳理在運(yun)、在建和(he)規(gui)劃750千伏(fu)(fu)電(dian)(dian)(dian)網(wang)存(cun)在的安全(quan)問題和(he)風(feng)險，全(quan)面加強750千伏(fu)(fu)電(dian)(dian)(dian)網(wang)規(gui)劃設(she)計、設(she)備(bei)選型、安裝調試、運(yun)行控(kong)制(zhi)、設(she)備(bei)運(yun)維等工作，確保750千伏(fu)(fu)電(dian)(dian)(dian)網(wang)安全(quan)穩(wen)定運(yun)行。
750千(qian)(qian)(qian)伏(fu)(fu)電(dian)網(wang)是西(xi)北(bei)電(dian)網(wang)骨干網(wang)架。750千(qian)(qian)(qian)伏(fu)(fu)輸(shu)電(dian)示范工程投(tou)運后，750千(qian)(qian)(qian)伏(fu)(fu)電(dian)網(wang)建設不斷加快(kuai)，目前已累(lei)計投(tou)產(chan)10站(zhan)14線(xian)，總容量870萬千(qian)(qian)(qian)伏(fu)(fu)安，線(xian)路2065千(qian)(qian)(qian)米。750千(qian)(qian)(qian)伏(fu)(fu)電(dian)網(wang)覆蓋陜、甘、青、寧四省(sheng)（自治區），跨省(sheng)輸(shu)電(dian)能力大幅提升。現有在(zai)建750千(qian)(qian)(qian)伏(fu)(fu)變(bian)電(dian)站(zhan)10座、線(xian)路19條。
當前，西(xi)北750千伏(fu)(fu)電(dian)(dian)網(wang)(wang)全(quan)面(mian)快速發(fa)展，同時(shi)處在重要的轉型期。750千伏(fu)(fu)骨干(gan)網(wang)(wang)架成(cheng)(cheng)網(wang)(wang)初(chu)期，面(mian)臨著與(yu)330千伏(fu)(fu)電(dian)(dian)網(wang)(wang)協調過渡、電(dian)(dian)網(wang)(wang)運(yun)行控制(zhi)、主(zhu)設備質量(liang)風險控制(zhi)和運(yun)行維護管控等問(wen)題。國家電(dian)(dian)網(wang)(wang)高度重視750千伏(fu)(fu)電(dian)(dian)網(wang)(wang)的安(an)全(quan)穩定運(yun)行工作(zuo)(zuo)。西(xi)北電(dian)(dian)網(wang)(wang)有限公(gong)司、五省（自治區）電(dian)(dian)力公(gong)司按照有關指(zhi)示精神，周密部署，積極落實，依據《國家電(dian)(dian)網(wang)(wang)公(gong)司西(xi)北750千伏(fu)(fu)電(dian)(dian)網(wang)(wang)安(an)全(quan)評(ping)(ping)(ping)估(gu)框架》及時(shi)制(zhi)定安(an)全(quan)評(ping)(ping)(ping)估(gu)細則，做(zuo)好自查工作(zuo)(zuo)。自評(ping)(ping)(ping)估(gu)報告已(yi)于5月(yue)底完成(cheng)(cheng)，6月(yue)1日起(qi)接受專家預評(ping)(ping)(ping)。
據悉，本次評(ping)(ping)估工(gong)作有規劃運行、生產管理等兩個專家(jia)(jia)(jia)組參與，將(jiang)于14日結束。專家(jia)(jia)(jia)們(men)將(jiang)進一步聽取各(ge)單位安全(quan)專項自查(cha)中發現(xian)的(de)(de)問題和應對措施，查(cha)找需(xu)要(yao)改(gai)進和完(wan)善(shan)的(de)(de)部分，進一步完(wan)善(shan)安全(quan)評(ping)(ping)估報告。國家(jia)(jia)(jia)電網(wang)將(jiang)根據評(ping)(ping)估情況制定(ding)切實(shi)可行的(de)(de)《西北750千(qian)伏電網(wang)安全(quan)穩定(ding)工(gong)作實(shi)施方案》。
