風(feng)(feng)能資(zi)源(yuan)(yuan)豐富，適(shi)合長(chang)期開發。內蒙(meng)古自治(zhi)區離地(di)10m高度(du)風(feng)(feng)能資(zi)源(yuan)(yuan)總儲(chu)量(liang)(liang)為8.98億(yi)kW，技術可(ke)開發量(liang)(liang)為1.5億(yi)kW，其(qi)中(zhong)蒙(meng)東(dong)地(di)區面積約(yue)占內蒙(meng)古自治(zhi)區的40%，風(feng)(feng)能資(zi)源(yuan)(yuan)儲(chu)量(liang)(liang)約(yue)占整個自治(zhi)區風(feng)(feng)能資(zi)源(yuan)(yuan)儲(chu)量(liang)(liang)的32%，風(feng)(feng)能資(zi)源(yuan)(yuan)的技術可(ke)開發量(liang)(liang)約(yue)為4300萬kW。
建(jian)(jian)(jian)(jian)場條(tiao)件好，基(ji)(ji)(ji)建(jian)(jian)(jian)(jian)成本低(di)。內(nei)蒙古(gu)自治區(qu)土地廣闊(kuo)，人口較少(shao)，土地資源豐富(fu)且價(jia)格低(di)廉(lian)、特別(bie)是蒙東(dong)地區(qu)有大量荒漠(mo)或半(ban)荒漠(mo)土地，地價(jia)低(di)廉(lian)，建(jian)(jian)(jian)(jian)風(feng)(feng)電(dian)(dian)場的(de)條(tiao)件較好。蒙東(dong)風(feng)(feng)電(dian)(dian)基(ji)(ji)(ji)地內(nei)無名勝(sheng)古(gu)跡、自然(ran)保(bao)(bao)護區(qu)等敏感環(huan)境保(bao)(bao)護目標，風(feng)(feng)電(dian)(dian)基(ji)(ji)(ji)地的(de)基(ji)(ji)(ji)建(jian)(jian)(jian)(jian)成本相對較低(di)，新建(jian)(jian)(jian)(jian)變電(dian)(dian)站、輸電(dian)(dian)線路(lu)走廊的(de)選址也較為(wei)容(rong)易。

統籌(chou)考慮蒙(meng)東、吉林千萬(wan)千瓦級(ji)風(feng)(feng)電(dian)(dian)(dian)(dian)基地(di)能源資源情況、地(di)理位置條件，并(bing)結合東北電(dian)(dian)(dian)(dian)網(wang)(wang)“十(shi)二五”發展規劃，吉林千萬(wan)千瓦級(ji)風(feng)(feng)電(dian)(dian)(dian)(dian)基地(di)立(li)足于吉林省(sheng)內乃至(zhi)東北全網(wang)(wang)進行消(xiao)(xiao)納(na)。根據國家(jia)特高壓(ya)電(dian)(dian)(dian)(dian)網(wang)(wang)規劃，到(dao)2020年，蒙(meng)東地(di)區規劃建成2個至(zhi)“三華(hua)”電(dian)(dian)(dian)(dian)網(wang)(wang)的特高壓(ya)直流輸電(dian)(dian)(dian)(dian)通道。蒙(meng)東風(feng)(feng)電(dian)(dian)(dian)(dian)基地(di)的風(feng)(feng)電(dian)(dian)(dian)(dian)除(chu)在東北電(dian)(dian)(dian)(dian)網(wang)(wang)消(xiao)(xiao)納(na)外，還有一部分需(xu)要通過特高壓(ya)直流采(cai)用“風(feng)(feng)火(huo)打捆”的方(fang)式送電(dian)(dian)(dian)(dian)“三華(hua)”電(dian)(dian)(dian)(dian)網(wang)(wang)消(xiao)(xiao)納(na)。其(qi)中東北地(di)區消(xiao)(xiao)納(na)656萬(wan)kW，“三華(hua)”電(dian)(dian)(dian)(dian)網(wang)(wang)消(xiao)(xiao)納(na)566萬(wan)kW。
蒙東地(di)區作為我國(guo)(guo)千萬千瓦級風電(dian)基地(di)之一(yi)，也(ye)是國(guo)(guo)家電(dian)網公司特(te)(te)高(gao)壓電(dian)網規劃的(de)(de)重要送端電(dian)源基地(di)之一(yi)。除滿(man)足自身(shen)經濟社會(hui)發(fa)展對電(dian)力的(de)(de)需求外(wai)，還主要通(tong)過特(te)(te)高(gao)壓電(dian)網送電(dian)“三(san)華”電(dian)網。
根據特高壓電網規劃(hua)，結合蒙(meng)東風電基地項(xiang)目前期工作進展情況，在輸(shu)電規劃(hua)論證中，考慮了以下主要原則：
①風電(dian)接入(ru)應遵(zun)行(xing)“建設(she)大基地、融(rong)入(ru)大電(dian)網(wang)”的規劃(hua)思路，滿足(zu)分片、分區接入(ru)原(yuan)則(ze)；
②風電(dian)的送出(chu)需進行統一規(gui)劃，在充分利用當地風電(dian)消納(na)能(neng)力的基礎上，剩余風電(dian)容量應(ying)通(tong)過超高壓及特高壓通(tong)道由東北(bei)及“三華”電(dian)網消納(na)；
③風(feng)(feng)電(dian)場應適當聯合與分(fen)組，形成相對獨立的(de)多個(ge)送(song)電(dian)通道(dao)，考慮(lv)到(dao)風(feng)(feng)電(dian)運行特點，避(bi)免(mian)風(feng)(feng)電(dian)送(song)電(dian)回路落點過于集中(zhong)，風(feng)(feng)電(dian)容量應分(fen)散接入(ru)電(dian)網；
④位于蒙東的大規模(mo)風(feng)電(dian)(dian)場主要應接入(ru)500kV電(dian)(dian)網運行；風(feng)電(dian)(dian)場容量大且集中的區域(yu)，宜選擇合適(shi)位置建(jian)設220kV或500kV匯集站，將風(feng)電(dian)(dian)場電(dian)(dian)力(li)匯集后直接送往500kV電(dian)(dian)網；
⑤對(dui)于地理(li)位置較(jiao)孤立的風電(dian)(dian)場(chang)，建議(yi)就(jiu)近(jin)接(jie)入(ru)當(dang)地220kV及以(yi)下電(dian)(dian)網運行，或對(dui)容量較(jiao)小的風電(dian)(dian)場(chang)進行匯(hui)集后送(song)入(ru)地區220kV電(dian)(dian)網。
到2020年，蒙東(dong)風(feng)(feng)(feng)電(dian)(dian)基地(di)規劃(hua)建設的(de)風(feng)(feng)(feng)電(dian)(dian)裝機容(rong)(rong)量(liang)將達到1222.5萬kW。其中，風(feng)(feng)(feng)電(dian)(dian)開(kai)(kai)(kai)發(fa)(fa)較為集中的(de)地(di)區(qu)(qu)為呼倫貝爾市(shi)新巴(ba)爾虎右(you)旗(qi)(qi)、通(tong)遼(liao)市(shi)開(kai)(kai)(kai)魯(lu)地(di)區(qu)(qu)、珠日(ri)河地(di)區(qu)(qu)以及赤(chi)峰(feng)市(shi)松山(shan)區(qu)(qu)、克什克騰(teng)旗(qi)(qi)、翁(weng)(weng)牛(niu)特(te)旗(qi)(qi)。呼倫貝爾市(shi)新巴(ba)爾虎右(you)旗(qi)(qi)風(feng)(feng)(feng)電(dian)(dian)開(kai)(kai)(kai)發(fa)(fa)容(rong)(rong)量(liang)約(yue)200萬kW，通(tong)遼(liao)市(shi)開(kai)(kai)(kai)魯(lu)地(di)區(qu)(qu)、珠日(ri)河地(di)區(qu)(qu)風(feng)(feng)(feng)電(dian)(dian)開(kai)(kai)(kai)發(fa)(fa)容(rong)(rong)量(liang)約(yue)270萬kW，赤(chi)峰(feng)市(shi)松山(shan)區(qu)(qu)、克什克騰(teng)旗(qi)(qi)、翁(weng)(weng)牛(niu)特(te)旗(qi)(qi)風(feng)(feng)(feng)電(dian)(dian)開(kai)(kai)(kai)發(fa)(fa)容(rong)(rong)量(liang)約(yue)390萬kW。剩余約(yue)362萬kW風(feng)(feng)(feng)電(dian)(dian)裝機地(di)理(li)位置分散且單個(ge)風(feng)(feng)(feng)電(dian)(dian)場容(rong)(rong)量(liang)較小。
蒙東(dong)風(feng)(feng)(feng)電基地規劃裝機容量較大，但蒙東(dong)地區負荷(he)水(shui)平較低，所發(fa)電力(li)需要大規模外(wai)送(song)。加快蒙東(dong)風(feng)(feng)(feng)電基地建設，對于(yu)促(cu)進清潔能(neng)源規模化開(kai)發(fa)，優化煤炭發(fa)展格局，支(zhi)撐我國經濟快速發(fa)展，促(cu)進智能(neng)電網發(fa)展戰(zhan)略和(he)規劃研(yan)究。低碳經濟發(fa)展具有(you)重要意義(yi)。根(gen)據能(neng)源資源流(liu)向的合理安排，蒙東(dong)風(feng)(feng)(feng)電開(kai)發(fa)外(wai)送(song)應考慮(lv)首先通過(guo)500kV電網送(song)至東(dong)北主網消納，其余風(feng)(feng)(feng)電采用“風(feng)(feng)(feng)火打捆”方式(shi)通過(guo)特高壓直流(liu)外(wai)送(song)“三華”電網。
