　　1.1、監(jiān)控點(diǎn)配置
　　本工程設(shè)置2個(gè)值班監(jiān)控點(diǎn)和3個(gè)后備監(jiān)控點(diǎn)。值班監(jiān)控點(diǎn)在正常運(yùn)行時(shí)完成對(duì)輔助車間各系統(tǒng)的監(jiān)控;后備監(jiān)控點(diǎn)作為調(diào)試、試運(yùn)行、檢修時(shí)的后備操作點(diǎn)，按無(wú)人值班考慮。一個(gè)值班監(jiān)控點(diǎn)設(shè)在單元機(jī)組集控室內(nèi), 配置4 套輔助車間控制系統(tǒng)操作員站，監(jiān)控對(duì)象為水務(wù)控制系統(tǒng);另一個(gè)監(jiān)控值班點(diǎn)設(shè)在輔控綜合樓，配置6 套輔助車間控制系統(tǒng)操作員站，監(jiān)控對(duì)象為脫硫、輸煤、除灰渣系統(tǒng)。輔控綜合樓工程師站有脫硫工程師站1 套，輔網(wǎng)工程師站1 套、SIS 接口裝置1 臺(tái)，歷史數(shù)據(jù)服務(wù)器1 套。3個(gè)后備監(jiān)控點(diǎn)按無(wú)人值班考慮，分別為化學(xué)水處理2個(gè)后備監(jiān)控點(diǎn)、凝結(jié)水1個(gè)后備監(jiān)控點(diǎn)。后備監(jiān)控點(diǎn)用于調(diào)試、檢修及試運(yùn)行期間的操作，具備針對(duì)本系統(tǒng)的獨(dú)立監(jiān)控能力與組態(tài)調(diào)試能力。
　　1.2、控制器與I/O 配置
　　整套控制系統(tǒng)配置25對(duì)冗余控制器，IO點(diǎn)配置規(guī)模為13000點(diǎn)左右。
　　(1)水務(wù)控制系統(tǒng)配置
　　綜合泵房、凈水處理配置1對(duì)控制器;
　　反滲透、化學(xué)除鹽、再生系統(tǒng)及化學(xué)電源系統(tǒng)配置2 對(duì)控制器;
　　每臺(tái)機(jī)組的凝結(jié)水精處理及汽水取樣配置2 對(duì)控制器;
　　凝結(jié)水精處理再生配置1對(duì)控制器;
