=======================================
火力發(fā)電廠自動(dòng)化
火力發(fā)電廠的自動(dòng)化項(xiàng)目包括:
1、廠內(nèi)機(jī)、爐、電運(yùn)行設(shè)備的安全檢測(cè),包括數(shù)據(jù)采集、狀態(tài)監(jiān)視、屏幕顯示、越限報(bào)警、故障檢出等。
2、計(jì)算機(jī)實(shí)時(shí)控制,實(shí)現(xiàn)由點(diǎn)火至并網(wǎng)的全部自動(dòng)起動(dòng)過程。
3、有功負(fù)荷的經(jīng)濟(jì)分配和自動(dòng)增減。
4、母線電壓控制和無(wú)功功率的自動(dòng)增減。
5、穩(wěn)定監(jiān)視和控制。采用的控制方式有兩種形式:一種是計(jì)算機(jī)輸出通過外圍設(shè)備去調(diào)整常規(guī)模擬式調(diào)節(jié)器的設(shè)定值而實(shí)現(xiàn)監(jiān)督控制;另一種是用計(jì)算機(jī)輸出外圍設(shè)備直接控制生產(chǎn)過程而實(shí)現(xiàn)直接數(shù)字控制。
