描述
1785-TR10B2
從升壓站(不包括升壓站)至電廠側的所有主廠房內電氣系統(tǒng)均納入DCS監(jiān)控，主要系統(tǒng)歸納為：
發(fā)變組系統(tǒng)(不包括變壓器本身的通風系統(tǒng))；
發(fā)電機勵磁系統(tǒng)；
高壓廠用電源系統(tǒng)(包括廠用電源正常切換)；
低壓廠用電源系統(tǒng)和400VPC；
高壓啟／備變電源系統(tǒng)(2臺機共用)；
柴油發(fā)電機組和保安電源(僅監(jiān)視)；
直流系統(tǒng)和UPS系統(tǒng)(僅監(jiān)視)；
自動同期系統(tǒng)；
廠用電快切系統(tǒng)。
電氣主要保護安全自動裝置因要求DCS實現其功能目前尚有一定的難度，并且要增加相當大的費用。原則上不要求通過DCS實現其功能，仍保留其裝置，但它們與DCS之間要有接口，常規(guī)方式采用硬接口。保留的保護自動專用裝置主要有如下：
發(fā)變組保護裝置；
自動準同期裝置(ASS)；
自動電壓調整裝置(AVR)；
廠用電快切裝置；
故障錄波裝置。
主廠房外輔助系統(tǒng)的電氣系統(tǒng)如輸煤、化水、制氫、電除塵等暫不納入DCS系統(tǒng)中。
