連日來，受冷空(kong)氣影(ying)響，四(si)川電網(wang)用(yong)(yong)電負荷(he)、用(yong)(yong)電量(liang)節節攀升(sheng)。11月19日四(si)川電網(wang)用(yong)(yong)電負荷(he)達到1819萬千瓦，用(yong)(yong)電量(liang)達3.35億千瓦時，繼18日后，用(yong)(yong)電負荷(he)及(ji)用(yong)(yong)電量(liang)再創歷(li)史新高。目前(qian)，四(si)川省(sheng)電力公(gong)司已(yi)啟動應急預案，做好迎(ying)峰度(du)冬(dong)的(de)各項準備(bei)，采取多(duo)項措(cuo)施，確保群(qun)眾溫暖過冬(dong)。
針對地震災區(qu)板房的(de)特(te)點及(ji)冬季(ji)負(fu)荷(he)預測(ce)情況，廣元電(dian)業局(ju)部署了迎峰度冬有序(xu)用(yong)電(dian)工作(zuo)——地震災區(qu)安(an)(an)置(zhi)點和(he)市民生活(huo)區(qu)在(zai)供電(dian)線(xian)路一律不納入(ru)拉閘限電(dian)序(xu)位表；對安(an)(an)置(zhi)點供電(dian)線(xian)路等進行(xing)隱(yin)患排查整改；開通95598專線(xian)服(fu)務(wu)電(dian)話，提高安(an)(an)置(zhi)點用(yong)電(dian)服(fu)務(wu)訴(su)求的(de)響應(ying)級別，同(tong)時配備大功率(lv)應(ying)急發電(dian)車。
今年(nian)四川入冬比往年(nian)提前(qian)，線(xian)(xian)(xian)路防覆(fu)冰工(gong)作(zuo)更加(jia)嚴峻。國家(jia)電(dian)網(wang)四川公司十分重視500千伏石雅(ya)一線(xian)(xian)(xian)提高抗冰能力改造工(gong)作(zuo)，認(ren)真落(luo)實施工(gong)方案，在(zai)現(xian)有覆(fu)冰在(zai)線(xian)(xian)(xian)監測的基(ji)礎上，新(xin)增設7個覆(fu)冰觀(guan)測點，以加(jia)強覆(fu)冰線(xian)(xian)(xian)路的觀(guan)測和分析工(gong)作(zuo)。
近年來四川(chuan)省(sheng)水(shui)(shui)電(dian)(dian)裝機增(zeng)長較快，一批大水(shui)(shui)庫(ku)電(dian)(dian)站相(xiang)繼投運(yun)，改變了(le)四川(chuan)枯水(shui)(shui)期嚴重(zhong)缺(que)電(dian)(dian)的局(ju)面(mian)。盡管(guan)今(jin)冬明春四川(chuan)省(sheng)各主要河流來水(shui)(shui)較往年平均偏少，但水(shui)(shui)電(dian)(dian)裝機規模明顯增(zeng)長，預(yu)計(ji)今(jin)冬明春四川(chuan)電(dian)(dian)網水(shui)(shui)電(dian)(dian)日均電(dian)(dian)量將達到1.3億~1.4億千(qian)瓦時，較2008年增(zeng)長約20%。
在火電(dian)(dian)(dian)方面，今年四(si)川(chuan)省電(dian)(dian)(dian)煤(mei)供需形勢平穩(wen)，各主要火電(dian)(dian)(dian)廠存煤(mei)相(xiang)對充足，截至(zhi)10月31日(ri)，四(si)川(chuan)電(dian)(dian)(dian)網全(quan)網存煤(mei)300萬(wan)噸。若不發生(sheng)重(zhong)大突發事件，今冬明春(chun)可維持800萬(wan)千瓦的火電(dian)(dian)(dian)持續開機容(rong)量(liang)，日(ri)均發電(dian)(dian)(dian)量(liang)約1.5億千瓦時。
另外，考慮到火(huo)電(dian)(dian)運行和電(dian)(dian)煤供應存在的不確定因素，國家電(dian)(dian)網(wang)四川公司簽訂了今年(nian)下半年(nian)枯水期的外購電(dian)(dian)計劃，將通過特高壓(ya)試(shi)驗示范(fan)工程從華(hua)北電(dian)(dian)網(wang)輸入超(chao)過30萬(wan)千瓦的電(dian)(dian)力。
目前(qian)，國(guo)家電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)四川公司(si)正加快±500千伏德寶直(zhi)流工(gong)(gong)程建設進度，確(que)保年底單極投運，實現與西北電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)的(de)聯網(wang)(wang)(wang)(wang)。德寶直(zhi)流投運后(hou)，四川電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)將(jiang)(jiang)增加一(yi)(yi)條與西北電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)進行豐枯(ku)互(hu)濟和提(ti)供應急支援的(de)重(zhong)要通道(dao)。乘跨區聯網(wang)(wang)(wang)(wang)工(gong)(gong)程的(de)“東風”，繼去年之后(hou)，四川電(dian)(dian)(dian)網(wang)(wang)(wang)(wang)將(jiang)(jiang)再次迎來一(yi)(yi)個不(bu)缺(que)電(dian)(dian)(dian)的(de)“暖冬”。
