　　近日，江西電(dian)(dian)網充(chong)分發揮(hui)晉(jin)東南(nan)—南(nan)陽—荊門1000千(qian)伏(fu)特高(gao)壓輸(shu)電(dian)(dian)工程(cheng)大功率遠距離輸(shu)電(dian)(dian)優勢，變運煤為輸(shu)電(dian)(dian)，在(zai)用電(dian)(dian)高(gao)峰(feng)時期每天(tian)從(cong)外(wai)輸(shu)入電(dian)(dian)力達110萬(wan)千(qian)瓦(wa)，成功確(que)保了江西電(dian)(dian)網未拉閘限電(dian)(dian)和電(dian)(dian)網的(de)安全(quan)穩定運行(xing)。

　　據了解，2009年，特高(gao)(gao)(gao)(gao)(gao)壓(ya)(ya)入(ru)贛電(dian)(dian)(dian)量達10.52億千瓦時，電(dian)(dian)(dian)網(wang)變(bian)運煤(mei)(mei)為(wei)輸(shu)(shu)電(dian)(dian)(dian)，減(jian)少(shao)江(jiang)(jiang)西(xi)(xi)煤(mei)(mei)炭(tan)運力(li)約(yue)58萬(wan)(wan)噸，減(jian)少(shao)省內二氧化碳(tan)排(pai)(pai)放150萬(wan)(wan)噸，減(jian)少(shao)二氧化硫排(pai)(pai)放7165噸。入(ru)冬以來(lai)，江(jiang)(jiang)西(xi)(xi)電(dian)(dian)(dian)網(wang)消納晉東南—南陽—荊(jing)門1000千伏特高(gao)(gao)(gao)(gao)(gao)壓(ya)(ya)輸(shu)(shu)電(dian)(dian)(dian)約(yue)4.38億千瓦時。在(zai)今年1月(yue)上(shang)旬(xun)江(jiang)(jiang)西(xi)(xi)最高(gao)(gao)(gao)(gao)(gao)用(yong)(yong)電(dian)(dian)(dian)負荷首次突破1000萬(wan)(wan)千瓦并三次創出歷史(shi)新高(gao)(gao)(gao)(gao)(gao)的(de)情況下，省內發(fa)電(dian)(dian)(dian)用(yong)(yong)煤(mei)(mei)儲備僅(jin)83萬(wan)(wan)噸左右，遠低(di)于迎峰度(du)(du)冬低(di)限要求的(de)160萬(wan)(wan)噸，各發(fa)電(dian)(dian)(dian)企業電(dian)(dian)(dian)煤(mei)(mei)庫存紛紛告(gao)急。在(zai)火電(dian)(dian)(dian)機組因(yin)(yin)缺煤(mei)(mei)出現發(fa)電(dian)(dian)(dian)能(neng)力(li)受限制的(de)同時，江(jiang)(jiang)西(xi)(xi)各水電(dian)(dian)(dian)站因(yin)(yin)枯水也出力(li)不足，使江(jiang)(jiang)西(xi)(xi)電(dian)(dian)(dian)網(wang)保(bao)電(dian)(dian)(dian)壓(ya)(ya)力(li)巨大。面對(dui)巨大，江(jiang)(jiang)西(xi)(xi)電(dian)(dian)(dian)網(wang)充分發(fa)揮(hui)特高(gao)(gao)(gao)(gao)(gao)壓(ya)(ya)線(xian)路發(fa)揮(hui)大功(gong)率遠距離輸(shu)(shu)電(dian)(dian)(dian)優勢，積(ji)極(ji)強化跨(kua)省區輸(shu)(shu)電(dian)(dian)(dian)調(diao)度(du)(du)，依賴晉東南—南陽—荊(jing)門、靈寶、德寶等特高(gao)(gao)(gao)(gao)(gao)壓(ya)(ya)輸(shu)(shu)電(dian)(dian)(dian)線(xian)路，在(zai)1月(yue)上(shang)旬(xun)用(yong)(yong)電(dian)(dian)(dian)高(gao)(gao)(gao)(gao)(gao)峰期，特高(gao)(gao)(gao)(gao)(gao)壓(ya)(ya)輸(shu)(shu)電(dian)(dian)(dian)線(xian)路入(ru)贛電(dian)(dian)(dian)力(li)平均每天達60萬(wan)(wan)千瓦以上(shang)，占省外入(ru)贛電(dian)(dian)(dian)力(li)的(de)近50%，這(zhe)種變(bian)運煤(mei)(mei)為(wei)輸(shu)(shu)電(dian)(dian)(dian)的(de)做法，在(zai)一定程度(du)(du)緩(huan)解了電(dian)(dian)(dian)煤(mei)(mei)短缺和鐵路運力(li)緊張，為(wei)彌補江(jiang)(jiang)西(xi)(xi)用(yong)(yong)電(dian)(dian)(dian)高(gao)(gao)(gao)(gao)(gao)峰時段的(de)電(dian)(dian)(dian)力(li)缺口，確保(bao)不拉閘限電(dian)(dian)(dian)發(fa)揮(hui)了關鍵作(zuo)用(yong)(yong)。

　　據(ju)介紹，江(jiang)(jiang)西(xi)是一(yi)次能(neng)源(yuan)缺乏(fa)省(sheng)份(fen)(fen)(fen)，70%的(de)電(dian)(dian)(dian)煤(mei)(mei)(mei)靠省(sheng)外調(diao)入(ru)，平均輸(shu)(shu)送(song)距離近1000公里，且(qie)90%以(yi)上(shang)靠鐵路運(yun)輸(shu)(shu)，每年的(de)電(dian)(dian)(dian)力(li)迎(ying)峰度冬(dong)，江(jiang)(jiang)西(xi)都是電(dian)(dian)(dian)煤(mei)(mei)(mei)最(zui)緊(jin)張(zhang)的(de)省(sheng)份(fen)(fen)(fen)之一(yi)，前幾就發生(sheng)過為保江(jiang)(jiang)西(xi)不斷(duan)煤(mei)(mei)(mei)停(ting)機(ji)而“在途截煤(mei)(mei)(mei)”的(de)情況(kuang)。今(jin)年1月份(fen)(fen)(fen)，由于煤(mei)(mei)(mei)炭(tan)短缺與運(yun)力(li)偏緊(jin)，造成江(jiang)(jiang)西(xi)發電(dian)(dian)(dian)用煤(mei)(mei)(mei)儲備僅83萬噸(dun)左右，低(di)于省(sheng)政府要求的(de)迎(ying)峰度冬(dong)存煤(mei)(mei)(mei)160萬噸(dun)的(de)低(di)限要求。有關(guan)專家指出，在輸(shu)(shu)煤(mei)(mei)(mei)的(de)同(tong)時，依賴(lai)特高壓電(dian)(dian)(dian)網(wang)輸(shu)(shu)電(dian)(dian)(dian)，實施輸(shu)(shu)煤(mei)(mei)(mei)與輸(shu)(shu)電(dian)(dian)(dian)并舉，是緩(huan)解江(jiang)(jiang)西(xi)電(dian)(dian)(dian)煤(mei)(mei)(mei)緊(jin)張(zhang)，確(que)保電(dian)(dian)(dian)力(li)供應(ying)的(de)有效手段。
