近日，中國能源建設集團廣東省電力設計研究院設計的500千伏惠茅線改造工程順利竣工投產，比原計劃整整提前了65天。該工程被稱為緩解廣東用電緊缺的“解渴工程”，是中國南方電網公司重點電網建設項目。隨著送電大通道的打通，5月份廣東將增加供電能力250萬—300萬千瓦，彌補廣東電力1/3缺口。廣東院在開展工程設計的過程中實現了一系列的技術創新。
據了(le)(le)解(jie)，今年廣(guang)東全(quan)(quan)社會最(zui)高負荷(he)將(jiang)(jiang)達8700萬(wan)千瓦，二季度將(jiang)(jiang)是廣(guang)東最(zui)缺電(dian)的時(shi)(shi)期，預計(ji)(ji)最(zui)大(da)(da)電(dian)力缺口將(jiang)(jiang)達950萬(wan)千瓦，這項(xiang)“解(jie)渴工程(cheng)(cheng)(cheng)”工期緊、任(ren)務重。廣(guang)東院在確(que)保工程(cheng)(cheng)(cheng)質量的同時(shi)(shi)，加大(da)(da)投入，銳意創新(xin)，攻克了(le)(le)多個設(she)計(ji)(ji)難(nan)關，創造(zao)了(le)(le)諸多南方(fang)電(dian)網的“第一”：500千伏電(dian)壓等級交流(liu)(liu)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)路中首(shou)次采(cai)(cai)用(yong)(yong)六分裂大(da)(da)截面(mian)導線(xian)(xian)(xian)(xian)(xian)(xian)(xian)，輸送(song)能力提(ti)高4倍；首(shou)次全(quan)(quan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)采(cai)(cai)用(yong)(yong)籠式剛性跳線(xian)(xian)(xian)(xian)(xian)(xian)(xian)，能減少80%以上因風吹跳線(xian)(xian)(xian)(xian)(xian)(xian)(xian)造(zao)成跳閘的幾率，大(da)(da)大(da)(da)提(ti)高供電(dian)可靠(kao)性；首(shou)個全(quan)(quan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)普通(tong)地(di)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)金(jin)具(ju)(ju)采(cai)(cai)用(yong)(yong)預絞式金(jin)具(ju)(ju)，具(ju)(ju)有應力分布均勻的特點，能較(jiao)好地(di)保護(hu)地(di)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)；首(shou)個采(cai)(cai)用(yong)(yong)“燕翅形(xing)”鐵(tie)塔(ta)的交流(liu)(liu)工程(cheng)(cheng)(cheng)，使全(quan)(quan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)節省塔(ta)材將(jiang)(jiang)近900萬(wan)元，更安(an)全(quan)(quan)美觀。通(tong)過優化設(she)計(ji)(ji)，工程(cheng)(cheng)(cheng)建設(she)對沿線(xian)(xian)(xian)(xian)(xian)(xian)(xian)百姓生活的影響被降(jiang)至(zhi)最(zui)低。據統計(ji)(ji)，惠茅全(quan)(quan)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)控制用(yong)(yong)電(dian)面(mian)積6.48平方(fang)公里，節約土地(di)19.44平方(fang)公里，土地(di)資源(yuan)利(li)用(yong)(yong)率提(ti)高75%。
