時(shi)，發電(dian)(dian)機將(jiang)成為(wei)電(dian)(dian)動(dong)機運(yun)行(xing)，即從系統中吸取(qu)有功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)，拖動(dong)汽(qi)(qi)輪(lun)(lun)機。這種運(yun)行(xing)工況對發電(dian)(dian)機并無影(ying)響，但是對汽(qi)(qi)輪(lun)(lun)機而言，長時(shi)間無蒸汽(qi)(qi)運(yun)行(xing)將(jiang)會導致排汽(qi)(qi)缸溫度(du)升高及(ji)尾(wei)部葉(xie)片過(guo)熱。 　　由于汽(qi)(qi)缸中充滿了(le)不流動(dong)的(de)(de)蒸汽(qi)(qi)，它(ta)會與汽(qi)(qi)輪(lun)(lun)機葉(xie)片摩擦產生(sheng)熱，使汽(qi)(qi)輪(lun)(lun)機葉(xie)片過(guo)熱和低(di)壓缸排汽(qi)(qi)溫度(du)升高，低(di)壓缸整(zheng)體向(xiang)(xiang)上，轉子中心上移(yi)，在軸承座位置不變的(de)(de)情況下引(yin)起機組振動(dong)。逆(ni)(ni)功(gong)(gong)(gong)率(lv)保(bao)(bao)護(hu)的(de)(de)輸(shu)入量(liang)為(wei)機端PT二次三相(xiang)電(dian)(dian)壓及(ji)發電(dian)(dian)機CT二次三相(xiang)電(dian)(dian)流。 　　當發電(dian)(dian)機吸收有功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)時(shi)動(dong)作。因此，逆(ni)(ni)功(gong)(gong)(gong)率(lv)保(bao)(bao)護(hu)能(neng)夠(gou)確切(qie)地(di)反應(ying)功(gong)(gong)(gong)率(lv)反方向(xiang)(xiang)的(de)(de)異常工況，及(ji)時(shi)發出(chu)信(xin) ，在允許的(de)(de)時(shi)間內自(zi)動(dong)停機。2:程序跳(tiao)閘逆(ni)(ni)功(gong)(gong)(gong)率(lv)保(bao)(bao)護(hu)發電(dian)(dian)機的(de)(de)逆(ni)(ni)功(gong)(gong)(gong)率(lv)保(bao)(bao)護(hu)，除(chu)了(le)作為(wei)汽(qi)(qi)輪(lun)(lun)機的(de)(de)保(bao)(bao)護(hu)之(zhi)外，還可作為(wei)發電(dian)(dian)機組的(de)(de)程控跳(tiao)閘啟動(dong)元件，即稱之(zhi)為(wei)程序跳(tiao)閘逆(ni)(ni)功(gong)(gong)(gong)率(lv)保(bao)(bao)護(hu)。 　　停機時(shi)出(chu)現汽(qi)(qi)輪(lun)(lun)機超速現象的(de)(de)原因分析2.1大
