“倒送(song)電(dian)(dian)”就是反(fan)送(song)電(dian)(dian)過(guo)程(cheng)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(xiang)系(xi)統送(song)電(dian)(dian)，“倒送(song)電(dian)(dian)”就是從(cong)系(xi)統向(xiang)電(dian)(dian)廠送(song)電(dian)(dian)。

出現“倒送電”的過程和意(yi)義(yi)，主要是(shi)基于下(xia)面三個原因(yin)：

1、電(dian)(dian)廠(chang)基建過程(cheng)中(zhong)，需(xu)要臨(lin)時電(dian)(dian)源(yuan)，有時這個電(dian)(dian)源(yuan)會需(xu)要的(de)很大，特別是(shi)在建設的(de)后期，在建廠(chang)時修建的(de)臨(lin)時電(dian)(dian)源(yuan)會不夠(gou)用，就會從系統通過送電(dian)(dian)線(xian)路(lu)將電(dian)(dian)倒送過來(lai)，通過電(dian)(dian)廠(chang)的(de)T0變壓器進行供電(dian)(dian)；

2、電(dian)(dian)(dian)(dian)(dian)廠發電(dian)(dian)(dian)(dian)(dian)并網的(de)時候，也需要(yao)將系(xi)統的(de)電(dian)(dian)(dian)(dian)(dian)先倒(dao)(dao)送過來，然后(hou)調整發電(dian)(dian)(dian)(dian)(dian)機的(de)勵磁，使(shi)之與系(xi)統“同(tong)步”，然后(hou)并網發電(dian)(dian)(dian)(dian)(dian)；同(tong)時在電(dian)(dian)(dian)(dian)(dian)廠發電(dian)(dian)(dian)(dian)(dian)之前，需要(yao)將電(dian)(dian)(dian)(dian)(dian)廠的(de)設備先運轉起來，由于此(ci)時發電(dian)(dian)(dian)(dian)(dian)機還(huan)未(wei)發電(dian)(dian)(dian)(dian)(dian)，不能提供(gong)電(dian)(dian)(dian)(dian)(dian)源(yuan)，這個電(dian)(dian)(dian)(dian)(dian)源(yuan)就(jiu)只能通過系(xi)統“倒(dao)(dao)送電(dian)(dian)(dian)(dian)(dian)”來完成(cheng)；
