5月12日，甘肅電網750千伏(fu)輸(shu)變電工(gong)(gong)程(cheng)領導(dao)小組召開會議，工(gong)(gong)程(cheng)建(jian)設(she)、柔性輸(shu)電關鍵技術研(yan)究、風(feng)電預測系統建(jian)設(she)三項工(gong)(gong)作，成為該工(gong)(gong)程(cheng)的主要內容(rong)。
縱貫(guan)甘(gan)(gan)肅(su)境內的(de)750千(qian)伏輸(shu)電(dian)(dian)(dian)線路(lu)，是甘(gan)(gan)肅(su)電(dian)(dian)(dian)網(wang)(wang)和(he)新疆電(dian)(dian)(dian)網(wang)(wang)聯網(wang)(wang)的(de)主網(wang)(wang)架，也是酒泉千(qian)萬千(qian)瓦級風電(dian)(dian)(dian)送(song)出的(de)大通(tong)道。隨著750千(qian)伏輸(shu)電(dian)(dian)(dian)線路(lu)工(gong)程的(de)開工(gong)建設，甘(gan)(gan)肅(su)省電(dian)(dian)(dian)力公司相繼投資研發柔性輸(shu)電(dian)(dian)(dian)關鍵技術(shu)和(he)風電(dian)(dian)(dian)預測系統。
工程建設正(zheng)在按(an)照甘肅公司里程碑(bei)計劃逐步實施，處于可控(kong)之中，進(jin)展較(jiao)快的(de)750千(qian)伏永登(deng)—白銀(yin)輸電(dian)線路(lu)預計5月(yue)下旬開始(shi)架(jia)線；受可控(kong)高抗(kang)、串補裝置技(ji)術(shu)方(fang)案的(de)影響，河西750千(qian)伏金昌—酒泉—安西輸變電(dian)工程目前完成四(si)通一平，施工單(dan)位準備進(jin)場。
酒泉千(qian)(qian)(qian)萬千(qian)(qian)(qian)瓦(wa)級(ji)風(feng)電(dian)(dian)(dian)(dian)(dian)基地處(chu)于甘肅電(dian)(dian)(dian)(dian)(dian)網(wang)的(de)末端，距(ju)負荷中心蘭州約(yue)1000千(qian)(qian)(qian)米，2015年建成后裝機可達1271萬千(qian)(qian)(qian)瓦(wa)，類似(si)大容(rong)量、長距(ju)離傳(chuan)輸清潔能源的(de)風(feng)電(dian)(dian)(dian)(dian)(dian)工程，目前(qian)在(zai)(zai)世界(jie)上(shang)尚無先例。大規(gui)模(mo)風(feng)電(dian)(dian)(dian)(dian)(dian)外送必(bi)須借(jie)助柔(rou)性(xing)輸電(dian)(dian)(dian)(dian)(dian)技(ji)術。由(you)甘肅省電(dian)(dian)(dian)(dian)(dian)力(li)(li)公(gong)司和中國電(dian)(dian)(dian)(dian)(dian)力(li)(li)科學研究院合作的(de)750千(qian)(qian)(qian)伏(fu)輸電(dian)(dian)(dian)(dian)(dian)線(xian)路可控(kong)高抗(kang)、可控(kong)串補配(pei)置(zhi)方案等(deng)柔(rou)性(xing)輸電(dian)(dian)(dian)(dian)(dian)技(ji)術，目前(qian)還在(zai)(zai)研發之中。甘肅省電(dian)(dian)(dian)(dian)(dian)力(li)(li)公(gong)司正(zheng)組織(zhi)有關(guan)部門摸清技(ji)術需求，提(ti)出具(ju)體(ti)數(shu)據，確定最(zui)終技(ji)術路線(xian)。
建設(she)風(feng)(feng)電(dian)(dian)(dian)(dian)預測系統，是為了應對大(da)規模風(feng)(feng)電(dian)(dian)(dian)(dian)上網、確保電(dian)(dian)(dian)(dian)網安(an)全穩(wen)定運(yun)行而提出(chu)的(de)(de)。由于風(feng)(feng)電(dian)(dian)(dian)(dian)具有間歇性(xing)(xing)、波動性(xing)(xing)、隨機性(xing)(xing)的(de)(de)特點，必須加(jia)強(qiang)對風(feng)(feng)電(dian)(dian)(dian)(dian)場周(zhou)圍來風(feng)(feng)詳細數據的(de)(de)監測分析(xi)，為甘肅(su)省電(dian)(dian)(dian)(dian)力(li)調度中心科學(xue)調度提供(gong)依據。甘肅(su)省電(dian)(dian)(dian)(dian)力(li)公司擬加(jia)強(qiang)與(yu)專業機構的(de)(de)合作(zuo)，走市場化道路，建立一(yi)套更加(jia)科學(xue)實用的(de)(de)風(feng)(feng)電(dian)(dian)(dian)(dian)預測系統。
