11月11日，西北電網外(wai)(wai)(wai)送(song)(song)電量達(da)(da)到1.051億千瓦時，單日外(wai)(wai)(wai)送(song)(song)電量首(shou)次突破(po)1億千瓦時大(da)關，外(wai)(wai)(wai)送(song)(song)最大(da)負荷達(da)(da)511萬(wan)千瓦，占目前(qian)西北外(wai)(wai)(wai)送(song)(song)總(zong)容量的83.63%，日外(wai)(wai)(wai)送(song)(song)電量和外(wai)(wai)(wai)送(song)(song)負荷均(jun)創歷史(shi)新(xin)高。
隨著寧(ning)東(dong)—山東(dong)±660千伏直(zhi)流輸(shu)電(dian)(dian)示(shi)范工程順利投入(ru)試(shi)運行，西(xi)北(bei)電(dian)(dian)網(wang)外(wai)送(song)(song)最(zui)大容量達到611萬(wan)千瓦，西(xi)北(bei)外(wai)向型、送(song)(song)出(chu)型、規模(mo)型堅強(qiang)送(song)(song)端電(dian)(dian)網(wang)已(yi)初(chu)具規模(mo)，實現西(xi)北(bei)—華(hua)北(bei)、西(xi)北(bei)—華(hua)中(zhong)聯(lian)網(wang)，將(jiang)黃(huang)河上游水電(dian)(dian)、煤電(dian)(dian)基地(di)火電(dian)(dian)打捆送(song)(song)往四川、山東(dong)，有(you)力推進西(xi)北(bei)能源資源在(zai)更大范圍內優化配置，為緩(huan)解冬季華(hua)中(zhong)、華(hua)北(bei)電(dian)(dian)網(wang)缺電(dian)(dian)局面(mian)提供了強(qiang)大的電(dian)(dian)力支(zhi)撐。
為應對外送(song)(song)負(fu)荷(he)和網(wang)(wang)(wang)(wang)內用電負(fu)荷(he)高峰(feng)的到來，確保迎峰(feng)度冬和大負(fu)荷(he)外送(song)(song)期間(jian)電網(wang)(wang)(wang)(wang)安全(quan)穩(wen)定(ding)運行(xing)，西(xi)(xi)(xi)北(bei)電網(wang)(wang)(wang)(wang)有限公司加快全(quan)網(wang)(wang)(wang)(wang)檢修和設備投產速度，目前已實現(xian)750千伏統一(yi)電網(wang)(wang)(wang)(wang)覆蓋(gai)西(xi)(xi)(xi)北(bei)五省（區），強化了西(xi)(xi)(xi)北(bei)送(song)(song)端(duan)網(wang)(wang)(wang)(wang)架結構。
西北(bei)公(gong)司(si)(si)還(huan)指導主(zhu)要火電(dian)發電(dian)企(qi)業簽訂了年利用5000小時以上(shang)的中(zhong)長期(qi)合同(tong)，以黃河富余水電(dian)進(jin)行短期(qi)調(diao)節(jie)，充分發揮“電(dian)量(liang)(liang)庫”交易機(ji)制，提前做(zuo)好(hao)外送電(dian)力電(dian)量(liang)(liang)組織工作(zuo)。同(tong)時，密切關(guan)注天氣變(bian)化，提高負(fu)荷預測的準確性，合理(li)安排機(ji)組開機(ji)方式，加大(da)電(dian)煤儲運工作(zuo)力度，提前落(luo)實全網發用電(dian)平衡。此(ci)外，西北(bei)公(gong)司(si)(si)還(huan)將440萬千瓦(wa)火電(dian)裝機(ji)列(lie)入外送裝機(ji)序(xu)列(lie)，協調(diao)西北(bei)區(qu)域(yu)內(nei)主(zhu)要水、火電(dian)廠留足備(bei)用容量(liang)(liang)，提前做(zuo)好(hao)電(dian)力電(dian)量(liang)(liang)平衡工作(zuo)。
