近日，四川(chuan)、重慶多地發布高溫(wen)預警，氣溫(wen)超過40攝氏(shi)度，持續高溫(wen)天氣導致電(dian)(dian)網用(yong)電(dian)(dian)負荷(he)屢(lv)創(chuang)新高。高溫(wen)考(kao)驗下，國網四川(chuan)省(sheng)電(dian)(dian)力公司、國網重慶市電(dian)(dian)力公司提前部(bu)署，科學應(ying)對，合理調度，全力保障居(ju)民用(yong)電(dian)(dian)和全市工(gong)(gong)業生產用(yong)電(dian)(dian)，切實做好迎(ying)峰度夏(xia)攻堅(jian)時(shi)期各項(xiang)工(gong)(gong)作，確保電(dian)(dian)網運行平穩，電(dian)(dian)力供應(ying)可(ke)靠(kao)。

據(ju)悉，此輪(lun)(lun)高(gao)(gao)溫持(chi)(chi)續(xu)時間長、溫度(du)高(gao)(gao)。四川省(sheng)連續(xu)發(fa)布多(duo)個高(gao)(gao)溫橙色(se)預警，高(gao)(gao)溫酷熱天(tian)(tian)氣(qi)(qi)已(yi)持(chi)(chi)續(xu)10天(tian)(tian)，電(dian)(dian)(dian)網用(yong)(yong)電(dian)(dian)(dian)負荷不斷攀升，特別是成都、宜賓、自貢(gong)、瀘州(zhou)、南充、眉山(shan)、遂寧(ning)、內江等地8月(yue)22日(ri)用(yong)(yong)電(dian)(dian)(dian)量均創(chuang)(chuang)歷史(shi)新(xin)高(gao)(gao)。成都電(dian)(dian)(dian)網形(xing)勢嚴(yan)峻，電(dian)(dian)(dian)網用(yong)(yong)電(dian)(dian)(dian)負荷連續(xu)13次(ci)創(chuang)(chuang)歷史(shi)新(xin)高(gao)(gao)，并(bing)已(yi)啟動迎峰度(du)夏一(yi)級響應。今年，受(shou)厄爾尼諾(nuo)現象影響，重慶市(shi)極端氣(qi)(qi)候變化頻繁，出(chu)現了三輪(lun)(lun)持(chi)(chi)續(xu)高(gao)(gao)溫天(tian)(tian)氣(qi)(qi)。8月(yue)24日(ri)，重慶市(shi)氣(qi)(qi)象臺發(fa)布高(gao)(gao)溫紅色(se)預警，局部地區氣(qi)(qi)溫突破40攝氏度(du)。

近期，川(chuan)(chuan)渝兩地電(dian)(dian)(dian)網(wang)用(yong)電(dian)(dian)(dian)負(fu)荷(he)(he)均(jun)較(jiao)去(qu)年(nian)大幅增(zeng)長。8月(yue)22日(ri)(ri)，四(si)(si)川(chuan)(chuan)電(dian)(dian)(dian)網(wang)用(yong)電(dian)(dian)(dian)量(liang)64368.9萬千(qian)瓦，日(ri)(ri)最大供電(dian)(dian)(dian)負(fu)荷(he)(he)3236萬千(qian)瓦，發電(dian)(dian)(dian)量(liang)68932萬千(qian)瓦，均(jun)創歷史新高。據了解，今(jin)年(nian)四(si)(si)川(chuan)(chuan)電(dian)(dian)(dian)網(wang)的用(yong)電(dian)(dian)(dian)負(fu)荷(he)(he)和日(ri)(ri)用(yong)電(dian)(dian)(dian)量(liang)均(jun)較(jiao)往年(nian)增(zeng)加了45％。7月(yue)以(yi)來，重慶電(dian)(dian)(dian)網(wang)負(fu)荷(he)(he)九創歷史新高，統調負(fu)荷(he)(he)最高達到(dao)1767萬千(qian)瓦，較(jiao)去(qu)年(nian)最大負(fu)荷(he)(he)增(zeng)長33.5%。

據統(tong)計，四川(chuan)電(dian)力負荷(he)缺口已突(tu)破20％，供(gong)電(dian)形勢十(shi)分嚴峻(jun)，輸配電(dian)線(xian)路及設備運(yun)行壓(ya)力較大。對(dui)此，國網四川(chuan)電(dian)力采取一(yi)系列措施(shi)確保設備設施(shi)安全(quan)運(yun)轉(zhuan)；同(tong)時組織(zhi)落(luo)實有(you)序用電(dian)方(fang)案，堅持“民生(sheng)(sheng)第一(yi)”，優先(xian)保障(zhang)居民生(sheng)(sheng)活、能源(yuan)生(sheng)(sheng)產供(gong)應(ying)企業，以及黨政機關、醫院、交通運(yun)輸、通訊、廣播電(dian)視媒體等重要(yao)客戶(hu)和重要(yao)設施(shi)的用電(dian)需求。

除落實有序用電(dian)(dian)(dian)方案以(yi)外，國網四川電(dian)(dian)(dian)力(li)還采(cai)取(qu)一系列(lie)措(cuo)施全(quan)力(li)以(yi)赴迎戰高溫(wen)(wen)。該公(gong)司(si)要求各相(xiang)關單位加(jia)派人(ren)手，加(jia)強設備(bei)巡(xun)視、測溫(wen)(wen)，特別(bie)在成都設置了168個搶(qiang)修駐(zhu)點，安排輸電(dian)(dian)(dian)、配電(dian)(dian)(dian)、變(bian)電(dian)(dian)(dian)各專(zhuan)業工(gong)種搶(qiang)修值班人(ren)員(yuan)8000余人(ren)，不分晝(zhou)夜(ye)24小(xiao)時組織搶(qiang)修、排除故障；采(cai)取(qu)沖洗、冰(bing)塊等方式(shi)為變(bian)壓(ya)器物理(li)降溫(wen)(wen)，確保(bao)輸變(bian)電(dian)(dian)(dian)設備(bei)正常運行；針對局部供電(dian)(dian)(dian)“卡脖子”地(di)區，為保(bao)障電(dian)(dian)(dian)網安全(quan)，不排除實施用電(dian)(dian)(dian)負荷控(kong)制措(cuo)施，緊急限電(dian)(dian)(dian)；在加(jia)強排查電(dian)(dian)(dian)網薄弱(ruo)點的同(tong)時，同(tong)步推進電(dian)(dian)(dian)網建設、農網改造升級(ji)等工(gong)程，積極采(cai)用“零(ling)點作業”、帶電(dian)(dian)(dian)作業等多種措(cuo)施，全(quan)力(li)以(yi)赴確保(bao)全(quan)川人(ren)民群(qun)眾清涼度夏(xia)。

針對(dui)今年的(de)高(gao)溫天氣，國(guo)(guo)網(wang)重慶(qing)電力提前謀(mou)劃(hua)，科(ke)學部(bu)署，投(tou)資50.2億(yi)元，完成57項度夏(xia)工程(cheng)及城市配電網(wang)改造，為打好(hao)迎峰度夏(xia)攻堅戰做(zuo)好(hao)充分準(zhun)備。當前，重慶(qing)電網(wang)持續(xu)經受高(gao)溫大負(fu)荷(he)考驗，負(fu)荷(he)保持高(gao)位運行。國(guo)(guo)網(wang)重慶(qing)電力加強組織領(ling)導，強化領(ling)導帶班，嚴格值班紀律，做(zuo)好(hao)與發電企業、客戶(hu)之間信息(xi)溝通；精心調度、科(ke)學運維，確保當前持續(xu)高(gao)負(fu)荷(he)和迎峰度夏(xia)期間電網(wang)安全(quan)穩定(ding)、電力可靠供(gong)應。

同時，國網(wang)重慶電(dian)(dian)(dian)(dian)力重點做(zuo)(zuo)好(hao)五(wu)個方面的工作(zuo)：做(zuo)(zuo)好(hao)電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)量平衡(heng)工作(zuo)，精準負(fu)荷(he)(he)預測，用足市(shi)內(nei)火電(dian)(dian)(dian)(dian)、水電(dian)(dian)(dian)(dian)和(he)(he)計(ji)(ji)劃(hua)內(nei)區外(wai)來電(dian)(dian)(dian)(dian)，爭取(qu)國網(wang)華中分部(bu)增加(jia)(jia)臨時外(wai)購(gou)電(dian)(dian)(dian)(dian)力150萬千瓦(wa)，確(que)保(bao)電(dian)(dian)(dian)(dian)力供(gong)(gong)應(ying)充(chong)足，積極(ji)推(tui)進500千伏川(chuan)渝第(di)三(san)通道工程建(jian)設(she), 建(jian)成后(hou)增加(jia)(jia)川(chuan)渝通道輸送能力200萬千瓦(wa)；精心調(diao)度電(dian)(dian)(dian)(dian)網(wang)，嚴格執行(xing)(xing)西南(nan)電(dian)(dian)(dian)(dian)網(wang)夏季穩(wen)定規(gui)定，合理調(diao)整重載(zai)斷面和(he)(he)設(she)備(bei)潮流，優化安排電(dian)(dian)(dian)(dian)網(wang)運(yun)行(xing)(xing)方式(shi)，嚴禁電(dian)(dian)(dian)(dian)網(wang)超(chao)穩(wen)定極(ji)限、設(she)備(bei)超(chao)負(fu)荷(he)(he)運(yun)行(xing)(xing)；全力做(zuo)(zuo)好(hao)設(she)備(bei)運(yun)維監控，加(jia)(jia)強(qiang)重載(zai)主(zhu)變(bian)、重要(yao)線路通道特巡(xun)維護，及時處理高溫大負(fu)荷(he)(he)期(qi)間設(she)備(bei)缺陷(xian)，確(que)保(bao)電(dian)(dian)(dian)(dian)網(wang)設(she)備(bei)安全運(yun)行(xing)(xing)；做(zuo)(zuo)好(hao)并網(wang)電(dian)(dian)(dian)(dian)廠(chang)協調(diao)，督促加(jia)(jia)強(qiang)機組檢修安排和(he)(he)運(yun)行(xing)(xing)維護管理，做(zuo)(zuo)好(hao)電(dian)(dian)(dian)(dian)煤儲備(bei)，防(fang)止非計(ji)(ji)劃(hua)停運(yun)；加(jia)(jia)強(qiang)應(ying)急(ji)(ji)值(zhi)守和(he)(he)搶修隊伍及應(ying)急(ji)(ji)物(wu)資保(bao)障，遇到故障及時搶修恢復供(gong)(gong)電(dian)(dian)(dian)(dian)。
