　大唐南京電廠建設(shè)規(guī)模是2臺(tái)660MW超超臨界燃煤發(fā)電機(jī)組。按照大唐集團(tuán)公司的精神和設(shè)計(jì)原則：第一要采用新技術(shù)，來提高自動(dòng)化水平，第二要降低電廠的建設(shè)投資成本，第三在運(yùn)行之后，要進(jìn)行運(yùn)行方式的改革，以實(shí)現(xiàn)減員增效。按照這樣一個(gè)原則，在輔助車間的技術(shù)方案選型上，打破了常規(guī)方案的局限，選用了集中控制方案;在硬件平臺(tái)的選擇上，將PLC和DCS放在一起進(jìn)行比較，最終經(jīng)過招投標(biāo)選擇了性價(jià)比更好，更加適合集中控制應(yīng)用要求的科遠(yuǎn)NT6000分散控制系統(tǒng)。同時(shí)在部分系統(tǒng)中，采用了現(xiàn)場總線技術(shù)，為現(xiàn)場總線技術(shù)在火電廠的應(yīng)用，進(jìn)行了有益的嘗試。
　　1、控制系統(tǒng)配置
　　大唐南京電廠全廠輔助系統(tǒng)(車間)集中控制系統(tǒng)的控制范圍包括：綜合泵房、凈水系統(tǒng)、鍋爐補(bǔ)給水系統(tǒng)、兩臺(tái)機(jī)組的凝結(jié)水精處理及再生設(shè)備，化學(xué)取樣加藥系統(tǒng)、機(jī)組排水槽、脫硝氨區(qū)、工業(yè)和脫硫廢水處理、生活污水處理、煤泥水處理、暖通、輸煤、除灰系統(tǒng)、除渣、電除塵和脫硫等工藝系統(tǒng)。按照工藝系統(tǒng)，控制系統(tǒng)分成水務(wù)控制系統(tǒng)、灰煤渣控制系統(tǒng)、脫硫控制系統(tǒng);其中水務(wù)控制系統(tǒng)監(jiān)控點(diǎn)設(shè)在主控室內(nèi)，灰煤渣控制系統(tǒng)、脫硫控系統(tǒng)監(jiān)控點(diǎn)設(shè)在輔控綜合樓，每個(gè)監(jiān)控站均為全功能站，能夠監(jiān)控和操作全廠輔網(wǎng)設(shè)備狀態(tài)，同時(shí)通過權(quán)限設(shè)置不同的用戶，區(qū)別監(jiān)視和操作輸煤、除灰、脫硫等工藝系統(tǒng)設(shè)備，構(gòu)建了一個(gè)全廠輔助車間集中控制系統(tǒng)。
　　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 對控制器;
　　凝結(jié)水精處理再生配置1對控制器;
　　暖通系統(tǒng)配置2對控制器;
　　工業(yè)廢水處理及脫硫廢水配置2對控制器。
　　在廢水系統(tǒng)中采用了profibus現(xiàn)場總線技術(shù)，每條總線上分別有DP、PA設(shè)備組成，DP總線包含的設(shè)備有：馬達(dá)控制器、電磁閥導(dǎo)、電動(dòng)門執(zhí)行機(jī)構(gòu)等; PA總線包含的設(shè)備有：液位計(jì)、壓力變送器、流量等。替代了傳統(tǒng)IO點(diǎn)300點(diǎn)?，F(xiàn)場總線方案與常規(guī)系統(tǒng)相比，減少了常規(guī)IO模件的使用，減少大量電纜及電纜敷設(shè)工作，能夠獲取總線設(shè)備的大量現(xiàn)場信息，降低了工程造價(jià)，縮短了施工和調(diào)試時(shí)間，系統(tǒng)可靠性高，診斷信息豐富，便于后期維護(hù)。
　　(2)灰煤渣控制系統(tǒng)配置
　　輸煤綜合樓、轉(zhuǎn)運(yùn)站、雨水泵配置2對控制器;
