近日，上海(hai)電(dian)(dian)氣自主研發的首(shou)臺(tai)1240MW水氫氫發電(dian)(dian)機型式試(shi)驗在臨港基地完成。發電(dian)(dian)機效率、溫(wen)(wen)升、振動、噪聲、漏氫量五大(da)性(xing)能(neng)指標均優于設計(ji)預(yu)期，總體性(xing)能(neng)達到(dao)國際先進(jin)水平(ping)。上海(hai)電(dian)(dian)氣1240MW水氫氫發電(dian)(dian)機將服役陽西項目，是(shi)目前世界(jie)最大(da)單軸火電(dian)(dian)機組的全(quan)速汽輪發電(dian)(dian)機。與現(xian)有1000MW水氫氫發電(dian)(dian)機相比(bi)，定(ding)子電(dian)(dian)流增(zeng)加1.24倍(bei)，電(dian)(dian)動力(li)及(ji)發熱(re)量增(zeng)加1.54倍(bei)。針(zhen)對電(dian)(dian)動力(li)、溫(wen)(wen)升、模(mo)態及(ji)固定(ding)結構等(deng)變化(hua)，上海(hai)電(dian)(dian)氣在設計(ji)和(he)工藝(yi)上大(da)膽(dan)創(chuang)新，采用端部整(zheng)體灌膠設計(ji)，提高抗突然短路能(neng)力(li)和(he)整(zheng)機防暈水平(ping)。采用1:1實(shi)物模(mo)擬試(shi)驗和(he)三(san)維有限(xian)元分析、優化(hua)通風系統等(deng)，突破(po)了(le)大(da)型發電(dian)(dian)機定(ding)子端部繞(rao)組動力(li)特(te)性(xing)及(ji)模(mo)態設計(ji)等(deng)瓶頸。
