而使2臺(tái)機(jī)組的DCS耦合在一起。 在工程設(shè)計(jì)實(shí)際應(yīng)用過程中,依照DCS的特點(diǎn)采用了以下2種典型的方法來實(shí)現(xiàn)對(duì)公用系統(tǒng)的控制。一種是,在DCS的配置中,在2臺(tái)機(jī)組中配置相同的硬件和軟件,通過切換開關(guān)來實(shí)現(xiàn)操作權(quán)的轉(zhuǎn)換。外部設(shè)備的信號(hào)通過冗余配置(模擬量)或通過擴(kuò)展轉(zhuǎn)換(開關(guān)量)分別送入2套DCS系統(tǒng)。同時(shí)因保證不出現(xiàn)誤操作事故,還增加了相當(dāng)部分的判據(jù)條件和I/0測(cè)點(diǎn),這種方式的優(yōu)點(diǎn)是當(dāng)一臺(tái)機(jī)組停運(yùn)或檢修,可以較方便地對(duì)DCS進(jìn)行檢查,同時(shí)也增大了控制的可靠性,缺點(diǎn)是增加了外部設(shè)備的數(shù)量,增加了費(fèi)用。增加一個(gè)環(huán)節(jié)也就意味著增加了故障發(fā)生的可能。另一種為公用系統(tǒng)的控制全部通過公用環(huán)配置來實(shí)現(xiàn),2套DCS通過Tagnumber來實(shí)現(xiàn)控制
