　　工業(yè)循環(huán)水軋鋼工業(yè)中占有非常重要位，其水溫高低直接影響到加熱爐和軋機(jī)等設(shè)備安全和使用壽命。為及時(shí)準(zhǔn)確對(duì)循環(huán)水進(jìn)行監(jiān)控，萊鋼軋鋼廠中小型車間水處理采用浙大中控SUPCON JX—300X DCS控制系統(tǒng)。DCS控制系統(tǒng)把計(jì)算機(jī)、儀表和電控技術(shù)融合一起，實(shí)現(xiàn)了數(shù)據(jù)自動(dòng)采集、處理、工藝畫面顯示、參數(shù)超限報(bào)警、設(shè)備故障報(bào)警和報(bào)表打印等功能。并此基礎(chǔ)上開(kāi)發(fā)了針對(duì)循環(huán)水溫溫度閉環(huán)控制。
　　2、系統(tǒng)介紹
　　SUPCON JX—300XDCS采用高速工業(yè)以太網(wǎng)Scnet作為其過(guò)程控制網(wǎng)絡(luò)，系統(tǒng)由工程師站、操作站、控制站、過(guò)程控制單元等組成，配置靈活。水處理系統(tǒng)規(guī)模，水處理SUPCON DCS系統(tǒng)設(shè)計(jì)了1個(gè)控制站，1個(gè)操作站設(shè)置安全級(jí)別可兼做工程師站)，構(gòu)成兩級(jí)結(jié)構(gòu)?？刂普臼乾F(xiàn)場(chǎng)級(jí)，直接與現(xiàn)場(chǎng)設(shè)備交換數(shù)據(jù)，完成整個(gè)工業(yè)過(guò)程實(shí)時(shí)監(jiān)控功能。操作站(兼工程師站)是監(jiān)督控制級(jí)，即可完成對(duì)系統(tǒng)組態(tài)、又可實(shí)現(xiàn)對(duì)現(xiàn)場(chǎng)級(jí)檢測(cè)、控制、保護(hù)功能管理。SUPCON JX—300X DCS系統(tǒng)SCKey組態(tài)軟件是一個(gè)全面支持該系統(tǒng)各類控制方案組態(tài)軟件平臺(tái)。 SCKey組態(tài)軟件可完成整個(gè)系統(tǒng)控制站組態(tài)(系統(tǒng)I/O組態(tài)、控制方案組態(tài)等)、操作站組態(tài)(畫面設(shè)置、系統(tǒng)流程圖組態(tài)、系統(tǒng)報(bào)表組態(tài)等)。系統(tǒng)構(gòu)成如圖1所示。
　　3.1 方案設(shè)計(jì)
　　從生產(chǎn)熱線循環(huán)回來(lái)工業(yè)水流入1#、2#吸水井散熱，并吸水井塔頂1#和2#風(fēng)機(jī)進(jìn)行降溫，然后1#、2#吸水井底部共用一個(gè)出水管為下一個(gè)工序供水，水溫要求控制30oC以下。本系統(tǒng)吸水井出水管處安裝Cu50熱電阻對(duì)水溫檢測(cè)，把溫度信號(hào)T1送入DCS處理器，控制規(guī)律運(yùn)算后給出控制信號(hào)，控制變頻器來(lái)改變電機(jī)輸入電壓頻率，來(lái)改變電動(dòng)機(jī)轉(zhuǎn)速，帶動(dòng)風(fēng)機(jī)降溫，構(gòu)成一個(gè)閉環(huán)溫度控制系統(tǒng)。變頻器選用兩臺(tái)日本SANKEN(300KW)通用型變頻器，控制原理如圖2所示。
　　循環(huán)水吸水井底部熱交換特點(diǎn)，對(duì)1#、2#吸水井兩臺(tái)風(fēng)機(jī)電機(jī)進(jìn)行主/副控制，主/副電機(jī)不同速度曲線驅(qū)動(dòng)風(fēng)機(jī)運(yùn)轉(zhuǎn)。1#、2#電機(jī)可互為主/副電機(jī)選擇，極大方便了操作工操作。
　　3.2 軟件實(shí)現(xiàn)
　　為方便操作人員操作，操作站創(chuàng)建循環(huán)水溫度監(jiān)控畫面，可線顯示循環(huán)水溫度、變頻器速度反饋、報(bào)警等，進(jìn)行1#、2#風(fēng)機(jī)電機(jī)啟?？刂坪椭?副選擇控制。并切換安全等級(jí)線修改主/副電機(jī)控制回路中溫度、轉(zhuǎn)速等控制參數(shù)。
　　針對(duì)循環(huán)水溫度調(diào)節(jié)存大滯后性特點(diǎn)，對(duì)1#、2#風(fēng)機(jī)電機(jī)采用分段控制方法，主/副電機(jī)控制曲線如圖3所示：當(dāng)循環(huán)水溫度低于20oC時(shí)，主/副風(fēng)機(jī)電機(jī)變頻器輸出電壓頻率均為20HZ。當(dāng)循環(huán)水溫度變高時(shí)，主控制回路中變頻器輸出電壓頻率跟隨增大，當(dāng)循環(huán)水溫度高于24oC時(shí)，主電機(jī)全工頻運(yùn)轉(zhuǎn)。副電機(jī)循環(huán)水溫度升至23oC時(shí)，副控制回路增大副電機(jī)輸入電壓頻率，提高風(fēng)機(jī)轉(zhuǎn)速，當(dāng)循環(huán)水溫度高于28oC時(shí)，副電機(jī)全工頻運(yùn)轉(zhuǎn)，與主電機(jī)一起為循環(huán)水快速降溫。
