近日，上(shang)海(hai)電(dian)(dian)(dian)氣自(zi)主研發(fa)(fa)的(de)首臺1240MW水(shui)(shui)氫(qing)(qing)氫(qing)(qing)發(fa)(fa)電(dian)(dian)(dian)機(ji)型(xing)式試(shi)驗在臨港基地完成。發(fa)(fa)電(dian)(dian)(dian)機(ji)效率(lv)、溫升、振動(dong)、噪聲(sheng)、漏氫(qing)(qing)量(liang)五大(da)性(xing)能指標均優(you)于設(she)計(ji)(ji)預期，總體(ti)性(xing)能達到國(guo)際(ji)先(xian)進水(shui)(shui)平。上(shang)海(hai)電(dian)(dian)(dian)氣1240MW水(shui)(shui)氫(qing)(qing)氫(qing)(qing)發(fa)(fa)電(dian)(dian)(dian)機(ji)將服役陽西項目，是目前世界最大(da)單軸火電(dian)(dian)(dian)機(ji)組的(de)全速汽輪發(fa)(fa)電(dian)(dian)(dian)機(ji)。與現有1000MW水(shui)(shui)氫(qing)(qing)氫(qing)(qing)發(fa)(fa)電(dian)(dian)(dian)機(ji)相(xiang)比，定(ding)子電(dian)(dian)(dian)流增加(jia)(jia)1.24倍，電(dian)(dian)(dian)動(dong)力(li)(li)及發(fa)(fa)熱(re)量(liang)增加(jia)(jia)1.54倍。針對電(dian)(dian)(dian)動(dong)力(li)(li)、溫升、模(mo)態(tai)及固定(ding)結(jie)構(gou)等(deng)變化，上(shang)海(hai)電(dian)(dian)(dian)氣在設(she)計(ji)(ji)和工藝(yi)上(shang)大(da)膽創新(xin)，采用端部(bu)整體(ti)灌膠設(she)計(ji)(ji)，提(ti)高抗突(tu)然(ran)短(duan)路能力(li)(li)和整機(ji)防暈水(shui)(shui)平。采用1:1實物模(mo)擬試(shi)驗和三維有限元分析、優(you)化通風系統等(deng)，突(tu)破(po)了大(da)型(xing)發(fa)(fa)電(dian)(dian)(dian)機(ji)定(ding)子端部(bu)繞(rao)組動(dong)力(li)(li)特性(xing)及模(mo)態(tai)設(she)計(ji)(ji)等(deng)瓶頸。
