描述

通過系統(tǒng)服務器實現(xiàn)互連；控制網(wǎng)絡由ProfiBus-DP構成，實現(xiàn)現(xiàn)場控制站與過程I/O單元的通訊。該系統(tǒng)可由多組服務器組成，由此可將系統(tǒng)劃分為多個域。鎮(zhèn)海電廠215MW機組的DCS均劃分為兩個域，即主機域和輔機域。每個域由獨立的服務器、系統(tǒng)網(wǎng)絡和多個現(xiàn)場控制站組成，域內的數(shù)據(jù)單獨組態(tài)和管理，完成相對獨立的采集和控制功能；兩個域共享監(jiān)控網(wǎng)絡和工程師站，操作員站等則通過域名登錄到不同的域進行操作。

鎮(zhèn)海電廠DCS系統(tǒng)在升級改造前故障率相對較高，經(jīng)過對歷年來故障統(tǒng)計的分析，主要故障有主控制器故障、I/O模件故障、服務器故障、控制網(wǎng)絡故障和其它因素等引起，以2006年度為例，#3-＃6機組共發(fā)生DCS相關故障39起，其中主控制器故障13起，模件故障8起，占故障總數(shù)的53.8%，因此控制系統(tǒng)故障是熱工系統(tǒng)故障的主要因素，其分類統(tǒng)計情況
