“倒送(song)電(dian)(dian)”就是反送(song)電(dian)(dian)過程送(song)電(dian)(dian)。電(dian)(dian)廠送(song)電(dian)(dian)是將電(dian)(dian)廠發出的電(dian)(dian)向系(xi)統送(song)電(dian)(dian)，“倒送(song)電(dian)(dian)”就是從(cong)系(xi)統向電(dian)(dian)廠送(song)電(dian)(dian)。

出(chu)現“倒(dao)送電(dian)”的(de)過(guo)程(cheng)和意義，主要是基于(yu)下面三個原因：

1、電(dian)(dian)(dian)廠基建過(guo)程中，需要臨時(shi)(shi)電(dian)(dian)(dian)源(yuan)(yuan)，有時(shi)(shi)這個電(dian)(dian)(dian)源(yuan)(yuan)會需要的很大(da)，特別是在建設的后(hou)期(qi)，在建廠時(shi)(shi)修建的臨時(shi)(shi)電(dian)(dian)(dian)源(yuan)(yuan)會不夠用，就會從系統通(tong)過(guo)送電(dian)(dian)(dian)線路將電(dian)(dian)(dian)倒送過(guo)來，通(tong)過(guo)電(dian)(dian)(dian)廠的T0變壓器(qi)進(jin)行供電(dian)(dian)(dian)；

2、電(dian)廠發(fa)(fa)(fa)電(dian)并網的(de)(de)時(shi)候，也需(xu)要將系統(tong)(tong)(tong)的(de)(de)電(dian)先(xian)倒(dao)送過來，然后調整發(fa)(fa)(fa)電(dian)機的(de)(de)勵磁，使之與系統(tong)(tong)(tong)“同(tong)步”，然后并網發(fa)(fa)(fa)電(dian)；同(tong)時(shi)在(zai)電(dian)廠發(fa)(fa)(fa)電(dian)之前，需(xu)要將電(dian)廠的(de)(de)設備先(xian)運轉起(qi)來，由于此時(shi)發(fa)(fa)(fa)電(dian)機還未發(fa)(fa)(fa)電(dian)，不能(neng)提供電(dian)源，這個電(dian)源就(jiu)只能(neng)通過系統(tong)(tong)(tong)“倒(dao)送電(dian)”來完成；
