5月12日，甘肅電(dian)網(wang)750千伏輸變電(dian)工(gong)(gong)(gong)程(cheng)領導小(xiao)組(zu)召開會(hui)議(yi)，工(gong)(gong)(gong)程(cheng)建(jian)設、柔性(xing)輸電(dian)關(guan)鍵技術研(yan)究(jiu)、風(feng)電(dian)預測系統建(jian)設三項工(gong)(gong)(gong)作，成為該工(gong)(gong)(gong)程(cheng)的主(zhu)要內容。
縱貫甘肅境內(nei)的750千伏(fu)輸(shu)電(dian)(dian)(dian)線路，是甘肅電(dian)(dian)(dian)網和(he)新疆電(dian)(dian)(dian)網聯網的主網架，也是酒泉千萬千瓦級風電(dian)(dian)(dian)送(song)出的大通道。隨著750千伏(fu)輸(shu)電(dian)(dian)(dian)線路工程的開工建設，甘肅省電(dian)(dian)(dian)力公(gong)司相繼投資研(yan)發(fa)柔性輸(shu)電(dian)(dian)(dian)關鍵技術和(he)風電(dian)(dian)(dian)預測系統。
工程建設正在按(an)照甘肅公司里程碑計劃逐步實施，處于(yu)可控之中，進(jin)(jin)展較快的750千(qian)伏(fu)(fu)永(yong)登—白銀輸電線(xian)路預(yu)計5月下旬開始架線(xian)；受(shou)可控高抗、串補(bu)裝置技術(shu)方案(an)的影響(xiang)，河西750千(qian)伏(fu)(fu)金昌—酒泉—安西輸變電工程目前完成四通一平，施工單位(wei)準備(bei)進(jin)(jin)場(chang)。
酒泉(quan)千(qian)(qian)萬千(qian)(qian)瓦級風電(dian)(dian)(dian)(dian)基地處于甘(gan)肅(su)電(dian)(dian)(dian)(dian)網的(de)末端，距負荷(he)中心蘭州約1000千(qian)(qian)米，2015年建成(cheng)后裝機可(ke)(ke)達1271萬千(qian)(qian)瓦，類似大(da)容(rong)量、長距離傳輸(shu)(shu)清(qing)潔能(neng)源的(de)風電(dian)(dian)(dian)(dian)工(gong)程，目前在(zai)世界上尚(shang)無先(xian)例。大(da)規模風電(dian)(dian)(dian)(dian)外(wai)送必須借助柔(rou)性輸(shu)(shu)電(dian)(dian)(dian)(dian)技(ji)(ji)術(shu)。由(you)甘(gan)肅(su)省電(dian)(dian)(dian)(dian)力公(gong)司和中國(guo)電(dian)(dian)(dian)(dian)力科學研(yan)究院(yuan)合作的(de)750千(qian)(qian)伏輸(shu)(shu)電(dian)(dian)(dian)(dian)線路可(ke)(ke)控高抗、可(ke)(ke)控串補(bu)配置方(fang)案等柔(rou)性輸(shu)(shu)電(dian)(dian)(dian)(dian)技(ji)(ji)術(shu)，目前還在(zai)研(yan)發之(zhi)中。甘(gan)肅(su)省電(dian)(dian)(dian)(dian)力公(gong)司正組織有(you)關部門摸清(qing)技(ji)(ji)術(shu)需求(qiu)，提(ti)出具(ju)體數據，確定最終技(ji)(ji)術(shu)路線。
建(jian)設風(feng)電(dian)(dian)(dian)預(yu)測系(xi)(xi)統，是為(wei)了(le)應(ying)對大規模風(feng)電(dian)(dian)(dian)上網(wang)(wang)、確保(bao)電(dian)(dian)(dian)網(wang)(wang)安全(quan)穩定運(yun)行而提(ti)出的(de)。由于風(feng)電(dian)(dian)(dian)具(ju)有間歇性(xing)(xing)、波動性(xing)(xing)、隨機(ji)性(xing)(xing)的(de)特(te)點，必須加強對風(feng)電(dian)(dian)(dian)場周圍來風(feng)詳(xiang)細數據的(de)監測分析，為(wei)甘(gan)肅省電(dian)(dian)(dian)力調度中(zhong)心科學調度提(ti)供(gong)依據。甘(gan)肅省電(dian)(dian)(dian)力公司擬加強與專業機(ji)構的(de)合作，走市場化道路，建(jian)立一套(tao)更加科學實用(yong)的(de)風(feng)電(dian)(dian)(dian)預(yu)測系(xi)(xi)統。
