6月27日(ri)，世界首(shou)座(zuo)分體式220kV海上(shang)升壓站在中國國電集團龍源(yuan)江蘇(su)大豐20萬千瓦海上(shang)風電項目場區成功吊裝。
該(gai)(gai)項(xiang)(xiang)目(mu)(mu)(mu)(mu)位(wei)于江蘇省鹽城市大(da)豐區外(wai)側東沙沙洲北部海(hai)(hai)域，場(chang)區東西(xi)長約(yue)16公(gong)里，其西(xi)側邊線(xian)離(li)海(hai)(hai)岸(an)線(xian)直(zhi)線(xian)最短距離(li)約(yue)24公(gong)里，海(hai)(hai)上(shang)(shang)升(sheng)(sheng)壓(ya)站設(she)計安(an)裝(zhuang)(zhuang)位(wei)置(zhi)距項(xiang)(xiang)目(mu)(mu)(mu)(mu)登陸點(dian)直(zhi)線(xian)距離(li)約(yue)為22公(gong)里。受海(hai)(hai)洋地質(zhi)環境影(ying)響，海(hai)(hai)上(shang)(shang)升(sheng)(sheng)壓(ya)站無(wu)法像陸上(shang)(shang)升(sheng)(sheng)壓(ya)站那樣逐(zhu)層建(jian)設(she)、逐(zhu)個(ge)安(an)裝(zhuang)(zhuang)。目(mu)(mu)(mu)(mu)前，國內外(wai)海(hai)(hai)上(shang)(shang)風電項(xiang)(xiang)目(mu)(mu)(mu)(mu)普遍(bian)采用整體式吊裝(zhuang)(zhuang)建(jian)設(she)方案，即海(hai)(hai)上(shang)(shang)升(sheng)(sheng)壓(ya)站上(shang)(shang)部組塊作為一個(ge)整體模(mo)(mo)塊，在(zai)岸(an)上(shang)(shang)制作完成(cheng)(cheng)后(hou)運(yun)輸到指定(ding)位(wei)置(zhi)，通過大(da)型起重(zhong)船安(an)裝(zhuang)(zhuang)。但該(gai)(gai)項(xiang)(xiang)目(mu)(mu)(mu)(mu)海(hai)(hai)上(shang)(shang)升(sheng)(sheng)壓(ya)站重(zhong)量超過2500噸(dun)，且設(she)計安(an)裝(zhuang)(zhuang)位(wei)置(zhi)水深(shen)不足(zu)，超大(da)型海(hai)(hai)上(shang)(shang)起重(zhong)船只(zhi)無(wu)法進入該(gai)(gai)區域施(shi)工(gong)(gong)。通過探索，龍源電力創(chuang)造性地采取“模(mo)(mo)塊化(hua)設(she)計、分(fen)體式安(an)裝(zhuang)(zhuang)”的(de)施(shi)工(gong)(gong)方案，將該(gai)(gai)項(xiang)(xiang)目(mu)(mu)(mu)(mu)海(hai)(hai)上(shang)(shang)升(sheng)(sheng)壓(ya)站按功能(neng)設(she)計成(cheng)(cheng)5個(ge)獨立模(mo)(mo)塊，分(fen)批(pi)運(yun)輸至升(sheng)(sheng)壓(ya)站設(she)計安(an)裝(zhuang)(zhuang)位(wei)置(zhi)，并(bing)實施(shi)分(fen)體式安(an)裝(zhuang)(zhuang)，僅花費4天時間(jian)，就成(cheng)(cheng)功完成(cheng)(cheng)世界首個(ge)分(fen)體式海(hai)(hai)上(shang)(shang)升(sheng)(sheng)壓(ya)站吊裝(zhuang)(zhuang)工(gong)(gong)作。龍源電力將加緊(jin)該(gai)(gai)項(xiang)(xiang)目(mu)(mu)(mu)(mu)海(hai)(hai)上(shang)(shang)升(sheng)(sheng)壓(ya)站的(de)調試工(gong)(gong)作，為項(xiang)(xiang)目(mu)(mu)(mu)(mu)早日投產、發電做好(hao)準備。
