2012年8月1日,印度官員宣(xuan)布,印度大面積(ji)斷電已經結束。印度發生的停(ting)電事(shi)故(gu),覆蓋了一半(ban)以上(shang)的國(guo)土,直接影響6億多人的生活,是這(zhe)個南亞(ya)國(guo)家(jia)11年來(lai)最嚴(yan)重(zhong)的停(ting)電事(shi)故(gu)。
印(yin)度北部(bu)(bu)和東部(bu)(bu)地區(qu)7月30日(ri)和31日(ri)連(lian)續發生兩次大(da)面積(ji)停(ting)電(dian)事故。突如其來的斷(duan)電(dian)導致交通陷(xian)入混亂,全國(guo)超過300列火車停(ting)運(yun),首都新德里的地鐵也全部(bu)(bu)停(ting)運(yun),造成(cheng)旅客大(da)量滯留,公路交通出現大(da)面積(ji)擁堵。一些礦工被困井下。銀(yin)行系(xi)統陷(xian)入癱瘓,一度給印(yin)度的金融交易帶(dai)來障礙。
第(di)一次(ci)事故發生后,印(yin)度(du)電(dian)(dian)力(li)部門排除(chu)故障(zhang),在(zai)停電(dian)(dian)后15個小時(shi)內基本恢復(fu)了電(dian)(dian)力(li)供(gong)應。但旁遮普邦(bang)、哈里亞納邦(bang)以及(ji)北(bei)(bei)方邦(bang)等(deng)幾(ji)個地區在(zai)供(gong)電(dian)(dian)恢復(fu)后繼續超負荷用(yong)電(dian)(dian),導致了第(di)二次(ci)大面(mian)積停電(dian)(dian)。印(yin)度(du)電(dian)(dian)力(li)部門因此不得不從鄰國(guo)輸入電(dian)(dian)力(li)來滿(man)足新德里的用(yong)電(dian)(dian)需求(qiu)。截(jie)至8月1日,印(yin)度(du)北(bei)(bei)部地區95%的電(dian)(dian)力(li)供(gong)應已恢復(fu)。
貝(bei)恩(en)咨詢公司(si)高級合伙人阿密特·辛(xin)哈認為,此次停(ting)電事故給印度(du)經(jing)濟敲響(xiang)了警(jing)鐘——印度(du)電力供應至(zhi)少需要(yao)保持每年6.5%至(zhi)7%的增速,否(fou)則將(jiang)會對該國制造(zao)業和出口企(qi)業造(zao)成傷害。
印度最(zui)大行業協會(hui)印度工商(shang)聯合會(hui)主席卡諾里亞說:“連續兩天如此大規(gui)模的停電,值得(de)我們密切關注,這當然(ran)會(hui)
對于商業投資環(huan)境本就存在不少(shao)問題的印度(du)(du)來說,此(ci)次大停電不僅影(ying)響企業生產和盈利水平,還影(ying)響到(dao)印度(du)(du)在外國投資者眼中的形象。
印(yin)度(du)(du)產業聯合會理事長錢德拉吉(ji)特·班(ban)納吉(ji)表(biao)示(shi),印(yin)度(du)(du)經(jing)濟近來(lai)增長放緩,外界本就對(dui)印(yin)度(du)(du)前景(jing)不(bu)太看好(hao),如今電網(wang)兩天內連續崩潰(kui)無疑使(shi)印(yin)度(du)(du)的(de)形象進(jin)一步(bu)受損,令(ling)有(you)(you)意投資(zi)印(yin)度(du)(du)的(de)外國企業望而(er)卻步(bu)。對(dui)于一個(ge)擁(yong)有(you)(you)世界約六分之(zhi)一人口的(de)新興經(jing)濟體,有(you)(you)必要(yao)使(shi)基礎設施建設與印(yin)度(du)(du)的(de)強國夢想相匹配。
世(shi)界媒體都在議(yi)論印度(du)大(da)(da)(da)(da)(da)停(ting)(ting)電(dian),但任(ren)何國(guo)家(jia)(jia)都不(bu)(bu)能(neng)否認(ren)自己也(ye)遭遇過(guo)大(da)(da)(da)(da)(da)停(ting)(ting)電(dian)的歷史,只(zhi)是規模(mo)和(he)破(po)壞程度(du)不(bu)(bu)同(tong)罷了。美國(guo)上世(shi)紀后半葉,至少出現(xian)三次(ci)大(da)(da)(da)(da)(da)規模(mo)停(ting)(ting)電(dian)事故,近(jin)十(shi)多年時間里,美國(guo)至少遭遇過(guo)數次(ci)大(da)(da)(da)(da)(da)停(ting)(ting)電(dian)。如(ru)2008年,佛羅里達州發生大(da)(da)(da)(da)(da)停(ting)(ting)電(dian),300萬人沒有(you)電(dian)力供應;2003年大(da)(da)(da)(da)(da)停(ting)(ting)電(dian),由密歇根州延(yan)伸至紐(niu)約(yue),最后蔓延(yan)到加(jia)拿大(da)(da)(da)(da)(da)。危機專家(jia)(jia)承(cheng)認(ren),“一次(ci)大(da)(da)(da)(da)(da)停(ting)(ting)電(dian),即使(shi)是數秒(miao)鐘,也(ye)不(bu)(bu)亞于(yu)一場大(da)(da)(da)(da)(da)地震帶來的破(po)壞”。
很多新興經(jing)(jing)濟體(ti)在經(jing)(jing)濟高(gao)增長的(de)(de)刺(ci)激或尋求經(jing)(jing)濟高(gao)增長的(de)(de)動機之下,只顧電(dian)力開(kai)發(fa),卻忽視(shi)電(dian)網安(an)全工(gong)作(zuo),對(dui)電(dian)網管(guan)理體(ti)制(zhi)改革(ge)方面(mian)重視(shi)不夠(gou),導致“缺(que)電(dian)”和“有電(dian)”下都斷電(dian)停(ting)電(dian)的(de)(de)情(qing)況(kuang),造成(cheng)大量的(de)(de)浪費和損(sun)失。印度(du)此次(ci)發(fa)生(sheng)的(de)(de)問題(ti),對(dui)印度(du)是個(ge)現實教訓,對(dui)世界各新興經(jing)(jing)濟體(ti)而言(yan),是給電(dian)網安(an)全上(shang)(shang)了一課。只要(yao)體(ti)認“大停(ting)電(dian)或也會(hui)發(fa)生(sheng)在我們身(shen)上(shang)(shang)”,那(nei)么,我們就應該從(cong)漠不關心(xin)(xin)等心(xin)(xin)態中(zhong)覺醒過(guo)來,把印度(du)問題(ti)視(shi)為(wei)自(zi)己(ji)的(de)(de)問題(ti),做好自(zi)己(ji)的(de)(de)安(an)全工(gong)作(zuo)。
印度北部和東部地區7月30日和31日連續發
生兩次大(da)面(mian)積停(ting)電(dian)事故(gu)。突(tu)如其(qi)來的(de)斷電(dian)導致交通(tong)陷入混亂,全國超過300列火車停(ting)運,首都新德(de)里的(de)地(di)鐵也全部停(ting)運,造成(cheng)旅客大(da)量滯留,公路交通(tong)出現(xian)大(da)面(mian)積擁堵(du)。一些礦工(gong)被困(kun)井(jing)下。銀行系統陷入癱(tan)瘓(huan),一度給印度的(de)金融交易帶來障礙。
第一次事(shi)故發生后(hou),印(yin)度電力部(bu)門排除(chu)故障,在停(ting)電后(hou)15個(ge)(ge)小(xiao)時內基本恢復(fu)了(le)電力供應。但(dan)旁遮普(pu)邦(bang)、哈里亞納邦(bang)以及北方邦(bang)等幾(ji)個(ge)(ge)地區(qu)在供電恢復(fu)后(hou)繼續超負荷用電,導(dao)致了(le)第二次大面積(ji)停(ting)電。印(yin)度電力部(bu)門因此(ci)不(bu)得不(bu)從鄰國輸(shu)入(ru)電力來滿足新(xin)德里的(de)用電需求。截(jie)至8月1日,印(yin)度北部(bu)地區(qu)95%的(de)電力供應已恢復(fu)。
貝恩咨詢公司高級合伙人(ren)阿密特·辛哈認為,此次(ci)停電(dian)事故給印(yin)度(du)經(jing)濟敲響了警鐘——印(yin)度(du)電(dian)力供應至少需(xu)要(yao)保(bao)持每年6.5%至7%的增速,否則(ze)將會對該(gai)國制造(zao)業和(he)出口企(qi)業造(zao)成傷害。
印度最大行(xing)業協會(hui)印度工商聯合會(hui)主(zhu)席卡(ka)諾(nuo)里亞說:“連續兩(liang)天如此大規模的停電,值(zhi)得我們密切關注,這(zhe)當然會(hui)
對于商業(ye)投資(zi)環境本就存在不少問(wen)題的印(yin)度來(lai)說,此次大(da)停電(dian)不僅影響(xiang)企業(ye)生產和盈(ying)利(li)水平,還(huan)影響(xiang)到(dao)印(yin)度在外國投資(zi)者眼(yan)中(zhong)的形(xing)象(xiang)。
印(yin)(yin)度產業(ye)聯合會(hui)理(li)事長(chang)(chang)錢德拉吉(ji)特(te)·班納(na)吉(ji)表(biao)示,印(yin)(yin)度經濟近來(lai)增長(chang)(chang)放緩,外界(jie)本就對(dui)印(yin)(yin)度前景不太看好,如今電(dian)網兩天內連續崩潰(kui)無疑使印(yin)(yin)度的(de)形象進一步受損,令有(you)意投(tou)資印(yin)(yin)度的(de)外國企業(ye)望而卻(que)步。對(dui)于一個擁有(you)世(shi)界(jie)約六分之一人(ren)口的(de)新(xin)興(xing)經濟體,有(you)必要使基礎設施建設與印(yin)(yin)度的(de)強國夢想相匹配。
世(shi)界媒(mei)體都(dou)在(zai)議論印度(du)大停(ting)電(dian)(dian),但任(ren)何國(guo)家都(dou)不能否認(ren)自己也(ye)遭(zao)遇過(guo)大停(ting)電(dian)(dian)的(de)歷史,只是(shi)規模和破(po)(po)壞(huai)程度(du)不同(tong)罷(ba)了。美國(guo)上世(shi)紀后半葉(xie),至少出現三(san)次(ci)大規模停(ting)電(dian)(dian)事故(gu),近(jin)十多年時間里(li),美國(guo)至少遭(zao)遇過(guo)數(shu)次(ci)大停(ting)電(dian)(dian)。如2008年,佛(fo)羅里(li)達州發生大停(ting)電(dian)(dian),300萬人(ren)沒(mei)有(you)電(dian)(dian)力(li)供應;2003年大停(ting)電(dian)(dian),由(you)密歇根州延伸至紐約,最后蔓(man)延到加拿大。危機專家承認(ren),“一(yi)次(ci)大停(ting)電(dian)(dian),即使是(shi)數(shu)秒鐘,也(ye)不亞(ya)于一(yi)場大地震帶來的(de)破(po)(po)壞(huai)”。
很(hen)多新興經濟(ji)體在經濟(ji)高增長(chang)的(de)刺激或尋(xun)求(qiu)經濟(ji)高增長(chang)的(de)動機之下,只顧(gu)電(dian)(dian)力開(kai)發,卻忽視(shi)電(dian)(dian)網(wang)(wang)安全(quan)工(gong)作(zuo),對(dui)電(dian)(dian)網(wang)(wang)管(guan)理體制改革(ge)方面重視(shi)不夠,導致“缺電(dian)(dian)”和“有電(dian)(dian)”下都(dou)斷(duan)電(dian)(dian)停電(dian)(dian)的(de)情況,造(zao)成大(da)量的(de)浪(lang)費和損失。印(yin)度(du)此(ci)次發生(sheng)的(de)問題,對(dui)印(yin)度(du)是個現實教(jiao)訓,對(dui)世界(jie)各新興經濟(ji)體而言,是給電(dian)(dian)網(wang)(wang)安全(quan)上了一課。只要體認(ren)“大(da)停電(dian)(dian)或也會發生(sheng)在我們身上”,那么,我們就應該從(cong)漠(mo)不關心等心態中覺(jue)醒過來,把印(yin)度(du)問題視(shi)為自己(ji)的(de)問題,做好自己(ji)的(de)安全(quan)工(gong)作(zuo)。

2印度“7.30","7.31”大停電事故直接原因
印度(du)電力部在(zai)事(shi)故(gu)(gu)后(hou)組成特別小組展(zhan)開全面(mian)的(de)事(shi)故(gu)(gu)調查,并于s月I6口公(gong)布了事(shi)故(gu)(gu)調查報(bao)告(gao),報(bao)告(gao)詳細地分析了引起印度(du)連續兩(liang)起人(ren)停電事(shi)故(gu)(gu)的(de)直接原(yuan)因。
2012年7月30口,由于Bina-Gwalior 400kV線(xian)路跳(tiao)開,在北部(bu)電(dian)(dian)網(wang)(wang)和西(xi)部(bu)電(dian)(dian)網(wang)(wang)解(jie)列(lie)后,由西(xi)部(bu)電(dian)(dian)網(wang)(wang)供給北部(bu)電(dian)(dian)網(wang)(wang)負荷(he)的(de)潮流(liu)轉移到“西(xi)部(bu)電(dian)(dian)網(wang)(wang)一(yi)東部(bu)電(dian)(dian)網(wang)(wang)一(yi)北部(bu)電(dian)(dian)網(wang)(wang)”的(de)聯絡通道,導致系(xi)統發生功率(lv)振(zhen)(zhen)蕩(dang)由于振(zhen)(zhen)蕩(dang)中心在北部(bu)電(dian)(dian)網(wang)(wang)和東部(bu)電(dian)(dian)網(wang)(wang)間的(de)斷面上,致使相應(ying)的(de)聯絡線(xian)跳(tiao)開,造成(cheng)北部(bu)電(dian)(dian)網(wang)(wang)和印度(du)交流(liu)互(hu)聯系(xi)統其他部(bu)分解(jie)列(lie)。由于系(xi)統頻率(lv)過低以及(ji)區(qu)域內(nei)進一(yi)步的(de)功率(lv)振(zhen)(zhen)蕩(dang),北部(bu)電(dian)(dian)力系(xi)統最(zui)終(zhong)崩(beng)潰。
2012年7月31口,由于(yu)(yu)Bina-Gwalior 400kV線(xian)路跳開,在(zai)(zai)(zai)北(bei)部電(dian)(dian)網(wang)和西部電(dian)(dian)網(wang)解(jie)(jie)列(lie)以(yi)后,用于(yu)(yu)滿足北(bei)部區(qu)(qu)(qu)域(yu)負荷的潮流轉移到“西部電(dian)(dian)網(wang)一(yi)東(dong)(dong)(dong)部電(dian)(dian)網(wang)一(yi)北(bei)部電(dian)(dian)網(wang)”的聯絡(luo)通道,導(dao)致系(xi)(xi)統(tong)(tong)發生功率(lv)振蕩(dang)7月31口的系(xi)(xi)統(tong)(tong)振蕩(dang)中心在(zai)(zai)(zai)東(dong)(dong)(dong)部電(dian)(dian)網(wang)內部,靠近(jin)東(dong)(dong)(dong)部電(dian)(dian)網(wang)和西部電(dian)(dian)網(wang)斷面,因此(ci),在(zai)(zai)(zai)導(dao)致了(le)東(dong)(dong)(dong)部電(dian)(dian)網(wang)內部相應線(xian)路跳開之后,東(dong)(dong)(dong)部電(dian)(dian)網(wang)中的一(yi)小部分(fen)(Ranchi和Rourkela),以(yi)及西部區(qu)(qu)(qu)域(yu)電(dian)(dian)網(wang)和印(yin)度交流互聯系(xi)(xi)統(tong)(tong)其他(ta)部分(fen)解(jie)(jie)列(lie)。這造成了(le)北(bei)部電(dian)(dian)網(wang)和東(dong)(dong)(dong)部電(dian)(dian)網(wang)間斷面的功率(lv)振蕩(dang),并進一(yi)步導(dao)致了(le)北(bei)部區(qu)(qu)(qu)域(yu)電(dian)(dian)網(wang)和“東(dong)(dong)(dong)部+東(dong)(dong)(dong)北(bei)部”系(xi)(xi)統(tong)(tong)的解(jie)(jie)列(lie)。隨后,所有3個區(qu)(qu)(qu)域(yu)電(dian)(dian)網(wang)(北(bei)部、東(dong)(dong)(dong)部、東(dong)(dong)(dong)北(bei)部)由于(yu)(yu)區(qu)(qu)(qu)域(yu)內部功率(lv)振蕩(dang)造成多同線(xian)路跳開,系(xi)(xi)統(tong)(tong)頻率(lv)過(guo)低以(yi)及在(zai)(zai)(zai)不(bu)同地區(qu)(qu)(qu)的過(guo)電(dian)(dian)壓,最終北(bei)部、東(dong)(dong)(dong)部、東(dong)(dong)(dong)北(bei)部電(dian)(dian)力(li)系(xi)(xi)統(tong)(tong)崩(beng)潰。
根據印度的調(diao)查(cha)報(bao)告,2次(ci)事故當天的故障錄波器結果均顯示,系統中并(bing)沒(mei)有監測到有故障發生。在2次(ci)事故發生前,由(you)于西(xi)部(bu)電網(wang)(wang)和北部(bu)電網(wang)(wang)斷面,以及靠近東部(bu)電網(wang)(wang)和西(xi)部(bu)電網(wang)(wang)斷面的多條區域間聯(lian)(lian)絡線(xian)停運導致跨區通道弱聯(lian)(lian)系,系統間的輸(shu)電能力被顯著削弱。西(xi)部(bu)電網(wang)(wang)和北部(bu)電網(wang)(wang)斷面均只(zhi)有Bina-Agra 400kV(單同)一條交流主干聯(lian)(lian)絡線(xian)路處(chu)于運行(xing)狀態。

1網架結構不夠堅強,區域間交換能力不足
受(shou)印(yin)度電(dian)力(li)(li)工(gong)業的(de)經(jing)營與管理體制(zhi)(zhi)限制(zhi)(zhi),各級電(dian)網(wang)建設缺乏區(qu)(qu)域間(jian)(jian)統籌協調,區(qu)(qu)域主(zhu)網(wang)架以400kV/220kV電(dian)磁環(huan)網(wang)為(wei)主(zhu),沒有合理的(de)分(fen)層(ceng)分(fen)區(qu)(qu),網(wang)架結構較易(yi)引發穩定破壞。400kV線路作為(wei)主(zhu)干網(wang)架己不滿足(zu)印(yin)度經(jing)濟(ji)的(de)快速增長對(dui)電(dian)力(li)(li)負荷的(de)需(xu)要,765kV系統剛剛啟動建設,還(huan)未成網(wang)。跨區(qu)(qu)主(zhu)網(wang)架之間(jian)(jian)呈弱(ruo)連接,一旦局部故障引發連鎖反應,或(huo)者(zhe)區(qu)(qu)域電(dian)網(wang)白身發電(dian)能(neng)力(li)(li)人幅減少,各區(qu)(qu)域間(jian)(jian)彼此難(nan)以形(xing)成有力(li)(li)的(de)支援,加入了(le)發生(sheng)人面(mian)積停電(dian)的(de)可(ke)能(neng)性。
2電網發展缺乏統一規劃
印(yin)(yin)(yin)(yin)(yin)度(du)電(dian)(dian)網(wang)(wang)(wang)規(gui)(gui)劃(hua)(hua)(hua)、建設主體和(he)(he)資產歸屬(shu)復雜,主要(yao)包括印(yin)(yin)(yin)(yin)(yin)度(du)國(guo)家(jia)電(dian)(dian)網(wang)(wang)(wang)公(gong)司、邦(bang)(bang)屬(shu)電(dian)(dian)力公(gong)司以及私(si)人企(qi)業印(yin)(yin)(yin)(yin)(yin)度(du)國(guo)家(jia)電(dian)(dian)網(wang)(wang)(wang)公(gong)司負責區(qu)域及跨(kua)區(qu)域輸電(dian)(dian)線路的(de)規(gui)(gui)劃(hua)(hua)(hua),邦(bang)(bang)屬(shu)電(dian)(dian)力公(gong)司負責邦(bang)(bang)內輸電(dian)(dian)網(wang)(wang)(wang)絡(luo)的(de)規(gui)(gui)劃(hua)(hua)(hua)。盡管由隸屬(shu)于印(yin)(yin)(yin)(yin)(yin)度(du)國(guo)家(jia)電(dian)(dian)網(wang)(wang)(wang)公(gong)司的(de)5個區(qu)域級(ji)電(dian)(dian)力調度(du)中(zhong)心(xin)負責協(xie)調和(he)(he)管理(li)(li)有(you)關(guan)邦(bang)(bang)之間(jian)輸電(dian)(dian)線路的(de)相關(guan)事(shi)務,但其對邦(bang)(bang)內電(dian)(dian)力公(gong)司并無管理(li)(li)關(guan)系,無力有(you)效實現跨(kua)區(qu)、跨(kua)邦(bang)(bang)和(he)(he)邦(bang)(bang)內電(dian)(dian)網(wang)(wang)(wang)的(de)統(tong)一(yi)規(gui)(gui)劃(hua)(hua)(hua),各區(qu)域間(jian)電(dian)(dian)網(wang)(wang)(wang)的(de)發展規(gui)(gui)劃(hua)(hua)(hua)較難(nan)形(xing)成合理(li)(li)的(de)匹配和(he)(he)有(you)效的(de)銜接。除上(shang)述所(suo)述的(de)長期電(dian)(dian)網(wang)(wang)(wang)規(gui)(gui)劃(hua)(hua)(hua)問題外,印(yin)(yin)(yin)(yin)(yin)度(du)電(dian)(dian)網(wang)(wang)(wang)還存在短期運(yun)行規(gui)(gui)劃(hua)(hua)(hua)中(zhong),區(qu)域電(dian)(dian)網(wang)(wang)(wang)、邦(bang)(bang)電(dian)(dian)網(wang)(wang)(wang)的(de)輸電(dian)(dian)線路停運(yun)計劃(hua)(hua)(hua)不協(xie)調的(de)嚴(yan)重問題,并因此直接造(zao)成了區(qu)域間(jian)聯絡(luo)線的(de)功率(lv)調控能力缺(que)失。
3電網缺乏統一調度機制
除了(le)固有的發電冗余不足,調(diao)(diao)峰能(neng)力弱等客觀原因外(wai),此次事故暴露出印(yin)度(du)(du)電網調(diao)(diao)度(du)(du)體制不健全,電網運行缺乏統一調(diao)(diao)度(du)(du),不同級調(diao)(diao)度(du)(du)機構約束能(neng)力弱、跨邦跨區調(diao)(diao)度(du)(du)協調(diao)(diao)能(neng)力不足,調(diao)(diao)度(du)(du)指揮(hui)不暢,調(diao)(diao)度(du)(du)指令失(shi)靈等問題。

4電力管理體制分散,缺乏統一管理
印度電(dian)力(li)(li)管(guan)理體制缺乏(fa)集(ji)約化,各邦(bang)政(zheng)府對電(dian)力(li)(li)改革(ge)擁(yong)有(you)(you)較(jiao)高白(bai)主權(quan),使得各邦(bang)改革(ge)進(jin)程不盡相同(tong),統(tong)籌協(xie)調發(fa)展實現困難。發(fa)、輸、配(pei)電(dian)所有(you)(you)權(quan)和經營權(quan)分散,利益主體多元(yuan),電(dian)網發(fa)展長(chang)期各白(bai)為政(zheng),注(zhu)重局部(bu)(bu)利益,不重視(shi)整體安全(quan),電(dian)網管(guan)理水平偏低、線損高、人部(bu)(bu)分電(dian)力(li)(li)企業處(chu)于虧(kui)損狀態、投資能(neng)力(li)(li)弱。
一(yi)方(fang)面,由于印度(du)推行(xing)(xing)以私有(you)化為(wei)方(fang)向的(de)(de)電(dian)力(li)(li)改(gai)革(ge),輸(shu)(shu)(shu)配電(dian)網(wang)在體(ti)(ti)(ti)制(zhi)上(shang)(shang)并非一(yi)體(ti)(ti)(ti)化運(yun)(yun)行(xing)(xing);另一(yi)方(fang)面,印度(du)電(dian)網(wang)管理(li)體(ti)(ti)(ti)制(zhi)為(wei)中央(yang)和邦(bang)2個層次的(de)(de)分散(san)管理(li)模式(shi),各(ge)邦(bang)政府對(dui)電(dian)力(li)(li)改(gai)革(ge)擁有(you)較(jiao)高白主(zhu)權邦(bang)電(dian)監會不受中央(yang)電(dian)監會管理(li),邦(bang)電(dian)監會在邦(bang)內發(fa)、輸(shu)(shu)(shu)、配、電(dian)力(li)(li)交易(yi)和輸(shu)(shu)(shu)電(dian)定(ding)價等(deng)方(fang)面有(you)較(jiao)高的(de)(de)白主(zhu)權這種整體(ti)(ti)(ti)層面比(bi)較(jiao)分散(san)的(de)(de)管理(li)體(ti)(ti)(ti)制(zhi)與(yu)(yu)模式(shi),在很人(ren)程(cheng)度(du)上(shang)(shang)造成了印度(du)電(dian)力(li)(li)發(fa)展很難形成統一(yi)、科學的(de)(de)規劃。加入了印度(du)電(dian)網(wang)建(jian)設(she)與(yu)(yu)運(yun)(yun)行(xing)(xing)難度(du),也影響了印度(du)電(dian)力(li)(li)企業運(yun)(yun)營與(yu)(yu)積極性,導致印度(du)電(dian)力(li)(li)在整體(ti)(ti)(ti)上(shang)(shang)統籌(chou)協調發(fa)展實現困難。
