近日，四川、重慶多地發布高(gao)溫(wen)預警，氣(qi)溫(wen)超過40攝氏(shi)度(du)，持續高(gao)溫(wen)天(tian)氣(qi)導(dao)致電網用(yong)電負(fu)荷屢創新高(gao)。高(gao)溫(wen)考驗下，國網四川省電力公司(si)、國網重慶市電力公司(si)提前部(bu)署，科(ke)學應對，合理(li)調度(du)，全(quan)力保障居民用(yong)電和全(quan)市工業生產用(yong)電，切(qie)實(shi)做好迎峰度(du)夏攻堅時期(qi)各項工作，確(que)保電網運行平穩，電力供(gong)應可靠。

據悉(xi)，此輪高(gao)(gao)溫(wen)持續時間長、溫(wen)度高(gao)(gao)。四川省連續發(fa)布多(duo)個高(gao)(gao)溫(wen)橙色預警(jing)，高(gao)(gao)溫(wen)酷熱天(tian)氣(qi)(qi)(qi)(qi)已持續10天(tian)，電(dian)(dian)網(wang)用電(dian)(dian)負荷(he)不(bu)斷攀升，特別是成(cheng)都、宜賓、自貢(gong)、瀘(lu)州、南充、眉山、遂寧、內江等地8月22日(ri)用電(dian)(dian)量均創(chuang)(chuang)歷史新高(gao)(gao)。成(cheng)都電(dian)(dian)網(wang)形勢嚴峻(jun)，電(dian)(dian)網(wang)用電(dian)(dian)負荷(he)連續13次創(chuang)(chuang)歷史新高(gao)(gao)，并(bing)已啟動迎峰度夏一級響應。今年(nian)，受厄爾尼(ni)諾現(xian)象影響，重慶(qing)市極端氣(qi)(qi)(qi)(qi)候變化頻(pin)繁(fan)，出現(xian)了三輪持續高(gao)(gao)溫(wen)天(tian)氣(qi)(qi)(qi)(qi)。8月24日(ri)，重慶(qing)市氣(qi)(qi)(qi)(qi)象臺發(fa)布高(gao)(gao)溫(wen)紅(hong)色預警(jing)，局部(bu)地區氣(qi)(qi)(qi)(qi)溫(wen)突破40攝氏度。

近期，川渝兩地電(dian)(dian)(dian)(dian)網(wang)(wang)用(yong)(yong)電(dian)(dian)(dian)(dian)負荷均較去年大(da)幅(fu)增(zeng)長。8月22日(ri)，四川電(dian)(dian)(dian)(dian)網(wang)(wang)用(yong)(yong)電(dian)(dian)(dian)(dian)量(liang)64368.9萬(wan)千瓦，日(ri)最大(da)供電(dian)(dian)(dian)(dian)負荷3236萬(wan)千瓦，發電(dian)(dian)(dian)(dian)量(liang)68932萬(wan)千瓦，均創歷史新高(gao)。據了(le)解，今年四川電(dian)(dian)(dian)(dian)網(wang)(wang)的用(yong)(yong)電(dian)(dian)(dian)(dian)負荷和日(ri)用(yong)(yong)電(dian)(dian)(dian)(dian)量(liang)均較往年增(zeng)加了(le)45％。7月以來(lai)，重慶(qing)電(dian)(dian)(dian)(dian)網(wang)(wang)負荷九創歷史新高(gao)，統調(diao)負荷最高(gao)達到1767萬(wan)千瓦，較去年最大(da)負荷增(zeng)長33.5%。

據(ju)統(tong)計，四川電(dian)力(li)負荷(he)缺口(kou)已突破20％，供(gong)電(dian)形勢十分嚴(yan)峻(jun)，輸(shu)配電(dian)線路及設(she)(she)(she)備(bei)運(yun)行壓(ya)力(li)較(jiao)大。對此，國網四川電(dian)力(li)采取(qu)一(yi)系列措(cuo)施(shi)(shi)確(que)保設(she)(she)(she)備(bei)設(she)(she)(she)施(shi)(shi)安全(quan)運(yun)轉；同時組(zu)織(zhi)落(luo)實有序(xu)用電(dian)方案，堅持“民生(sheng)第一(yi)”，優先保障居(ju)民生(sheng)活、能源(yuan)生(sheng)產供(gong)應企業，以及黨政機關、醫院、交通(tong)運(yun)輸(shu)、通(tong)訊(xun)、廣播電(dian)視媒體(ti)等(deng)重要客戶和重要設(she)(she)(she)施(shi)(shi)的(de)用電(dian)需求。

除(chu)落實(shi)有序用電(dian)(dian)方案(an)以外，國網(wang)(wang)(wang)(wang)四川電(dian)(dian)力還采(cai)取一系列措施(shi)全(quan)力以赴迎(ying)戰高(gao)溫。該公司要求各(ge)(ge)相關單位加派人手(shou)，加強設(she)備巡視、測(ce)溫，特別在成都設(she)置(zhi)了(le)168個(ge)搶修駐點，安排(pai)(pai)輸(shu)電(dian)(dian)、配電(dian)(dian)、變電(dian)(dian)各(ge)(ge)專業(ye)工種(zhong)搶修值班人員8000余(yu)人，不分晝(zhou)夜24小時組織(zhi)搶修、排(pai)(pai)除(chu)故障；采(cai)取沖洗、冰塊等(deng)方式為變壓器物理降溫，確保(bao)(bao)輸(shu)變電(dian)(dian)設(she)備正常運行；針對局部供電(dian)(dian)“卡(ka)脖子”地區，為保(bao)(bao)障電(dian)(dian)網(wang)(wang)(wang)(wang)安全(quan)，不排(pai)(pai)除(chu)實(shi)施(shi)用電(dian)(dian)負荷控制措施(shi)，緊急(ji)限電(dian)(dian)；在加強排(pai)(pai)查電(dian)(dian)網(wang)(wang)(wang)(wang)薄弱點的同時，同步推進電(dian)(dian)網(wang)(wang)(wang)(wang)建設(she)、農網(wang)(wang)(wang)(wang)改(gai)造升級等(deng)工程，積極采(cai)用“零(ling)點作業(ye)”、帶電(dian)(dian)作業(ye)等(deng)多種(zhong)措施(shi)，全(quan)力以赴確保(bao)(bao)全(quan)川人民群眾清(qing)涼(liang)度夏。

針對(dui)今年的高(gao)溫天氣，國網(wang)重慶(qing)電(dian)(dian)力(li)提前謀劃，科學部署(shu)，投資50.2億元，完成57項度(du)夏(xia)工程及(ji)城市配電(dian)(dian)網(wang)改造，為打好迎(ying)峰(feng)度(du)夏(xia)攻堅戰做好充分準備(bei)。當前，重慶(qing)電(dian)(dian)網(wang)持(chi)續經受(shou)高(gao)溫大負荷(he)考驗，負荷(he)保(bao)持(chi)高(gao)位運行。國網(wang)重慶(qing)電(dian)(dian)力(li)加強組織領導，強化(hua)領導帶班，嚴(yan)格值班紀(ji)律，做好與發(fa)電(dian)(dian)企(qi)業(ye)、客(ke)戶之間信息溝通；精心調度(du)、科學運維(wei)，確保(bao)當前持(chi)續高(gao)負荷(he)和迎(ying)峰(feng)度(du)夏(xia)期間電(dian)(dian)網(wang)安全穩定、電(dian)(dian)力(li)可靠供應(ying)。
