　　按照“重要線路在上面”的原(yuan)則，國家電網江(jiang)(jiang)蘇省電力公司將(jiang)連云港核電送出線路，由從(cong)其(qi)他線路下部(bu)穿越改為從(cong)其(qi)上部(bu)跨(kua)越。近日，江(jiang)(jiang)蘇公司透露，年(nian)初(chu)冰災(zai)后，江(jiang)(jiang)蘇公司進一步加(jia)強(qiang)電網科學規劃，以完善(shan)堅強(qiang)電網為目標，全面推進六大(da)工程建設。

　　目前(qian)，江(jiang)蘇(su)(su)電(dian)網(wang)(wang)(wang)內發電(dian)裝機（全(quan)口徑）共(gong)5600萬千(qian)(qian)瓦，預(yu)計今年全(quan)省統(tong)(tong)調用(yong)電(dian)最(zui)高負荷為5100萬千(qian)(qian)瓦、全(quan)社(she)會用(yong)電(dian)量3310億千(qian)(qian)瓦時(shi)。為了滿足江(jiang)蘇(su)(su)經濟發展對電(dian)力(li)的需(xu)求，國家電(dian)網(wang)(wang)(wang)公司(si)統(tong)(tong)籌安排，加快電(dian)網(wang)(wang)(wang)建設(she)步(bu)伐(fa)，加大跨省資(zi)源優(you)化配置力(li)度。目前(qian)，江(jiang)蘇(su)(su)電(dian)網(wang)(wang)(wang)跨省市500千(qian)(qian)伏聯絡(luo)線有8條，江(jiang)蘇(su)(su)電(dian)網(wang)(wang)(wang)安全(quan)穩定與浙江(jiang)、安徽、上海等周邊省市電(dian)網(wang)(wang)(wang)息(xi)息(xi)相關。

　　冰災過后，江蘇公司更加注重事(shi)前防范(fan)和增強抵(di)御能力，全(quan)面推進電(dian)網科(ke)學規劃工程(cheng)(cheng)、電(dian)源合理(li)接入系(xi)統工程(cheng)(cheng)、電(dian)網建設加強工程(cheng)(cheng)、電(dian)網生(sheng)命(ming)線工程(cheng)(cheng)、黑(hei)啟動工程(cheng)(cheng)、控(kong)制技術進步工程(cheng)(cheng)等六大工程(cheng)(cheng)建設。

　　電(dian)網(wang)(wang)(wang)科學規劃(hua)工(gong)(gong)程，是按(an)照(zhao)“1個(ge)500千(qian)(qian)伏(fu)(fu)主(zhu)網(wang)(wang)(wang)、20個(ge)左(zuo)右(you)220千(qian)(qian)伏(fu)(fu)分區(qu)(qu)電(dian)網(wang)(wang)(wang)、100個(ge)左(zuo)右(you)110千(qian)(qian)伏(fu)(fu)互(hu)供電(dian)網(wang)(wang)(wang)”結構進行電(dian)網(wang)(wang)(wang)規劃(hua)、設計(ji)和建設。該工(gong)(gong)程將使江蘇電(dian)網(wang)(wang)(wang)實現500千(qian)(qian)伏(fu)(fu)主(zhu)力線路縱橫架(jia)構、220千(qian)(qian)伏(fu)(fu)及以下(xia)線路環(huan)網(wang)(wang)(wang)互(hu)濟，最終實現500千(qian)(qian)伏(fu)(fu)覆蓋全省、220千(qian)(qian)伏(fu)(fu)分區(qu)(qu)互(hu)濟、110千(qian)(qian)伏(fu)(fu)靈(ling)活備供和上級故(gu)障、下(xia)級支援，避免出現局(ju)部“孤島(dao)”電(dian)網(wang)(wang)(wang)。

　　電(dian)源合理接入系統(tong)工(gong)程主(zhu)要是科(ke)學規(gui)劃電(dian)源分(fen)布。目前，接入江蘇500千伏(fu)、220千伏(fu)和(he)(he)110千伏(fu)及以下電(dian)網的(de)裝(zhuang)機(ji)(ji)(ji)容量分(fen)別占全(quan)(quan)省裝(zhuang)機(ji)(ji)(ji)總量的(de)30%、51%和(he)(he)19%。未來，負(fu)荷密集地區的(de)部分(fen)60萬(wan)千瓦機(ji)(ji)(ji)組也將接入220千伏(fu)系統(tong)，以減少500千伏(fu)建設投入，并(bing)有效避免(mian)一級(ji)電(dian)網失電(dian)影響全(quan)(quan)局的(de)情(qing)況。

　　電(dian)網建設(she)加強工(gong)程(cheng)是堅(jian)持(chi)沿路(lu)、沿河(he)、沿海的(de)電(dian)網發展思路(lu)，逐步(bu)將現存的(de)少量(liang)山區電(dian)力(li)線(xian)路(lu)移(yi)至路(lu)邊，結(jie)合江(jiang)蘇河(he)流、公(gong)路(lu)、鐵路(lu)和輸電(dian)線(xian)路(lu)密布(bu)交叉的(de)特點(dian)，提高(gao)“三跨”（跨河(he)、跨路(lu)、跨線(xian)）段(duan)線(xian)路(lu)設(she)計標(biao)準。目前，江(jiang)蘇公(gong)司(si)已(yi)排查500千伏、220千伏不(bu)符(fu)合新設(she)計標(biao)準跨越段(duan)共(gong)計895處(chu)。該工(gong)程(cheng)還包括塔(ta)(ta)(ta)型優化(hua)課題研(yan)究，重點(dian)研(yan)究鐵塔(ta)(ta)(ta)結(jie)構(gou)、桿件(jian)布(bu)置、材料選擇、節(jie)點(dian)構(gou)造等(deng)設(she)計，從細節(jie)上把住電(dian)網建設(she)和維護的(de)安全關口(kou)。據悉，江(jiang)蘇公(gong)司(si)已(yi)順利通(tong)過(guo)了(le)(le)新塔(ta)(ta)(ta)型覆(fu)冰破(po)壞試驗，新塔(ta)(ta)(ta)型強度(du)明(ming)顯增強，鐵塔(ta)(ta)(ta)導地線(xian)容許覆(fu)冰厚(hou)度(du)提高(gao)了(le)(le)20%～30%。

　　電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)生命線(xian)工(gong)程(cheng)即在極端情況(kuang)下保證電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)有20%左右的(de)供電(dian)(dian)(dian)(dian)能(neng)力(li)，可以(yi)維持社(she)會(hui)基本運轉(zhuan)需要和電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)恢(hui)復運行(xing)所需電(dian)(dian)(dian)(dian)源(yuan)，防止(zhi)電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)極端情況(kuang)下的(de)全線(xian)垮塌。黑啟(qi)動工(gong)程(cheng)即在外來電(dian)(dian)(dian)(dian)力(li)供應中斷、省內(nei)機(ji)組和電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)全停的(de)情況(kuang)下，緊急啟(qi)動預先(xian)準備(bei)的(de)發電(dian)(dian)(dian)(dian)機(ji)組，帶動附(fu)近機(ji)組發電(dian)(dian)(dian)(dian)，逐步啟(qi)動電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)。目前，蘇南和蘇中電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)已有備(bei)用燃(ran)機(ji)或抽水蓄能(neng)黑啟(qi)動電(dian)(dian)(dian)(dian)源(yuan)，蘇北黑啟(qi)動電(dian)(dian)(dian)(dian)源(yuan)建設方案正(zheng)在組織實(shi)施。控(kong)(kong)制技術進步工(gong)程(cheng)強調電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)(wang)調度控(kong)(kong)制手段從人工(gong)到計算機(ji)智能(neng)控(kong)(kong)制的(de)轉(zhuan)變。
