描述

Triconex 4351B

300MW及以上容量機(jī)組的熱工控制已全面采用DCS控制系統(tǒng),逐步形成了數(shù)據(jù)采集(DAS)、模擬量控制(MCS)、順序控制(SCS)、燃燒器管理(BMS)四大系統(tǒng)。從實(shí)際運(yùn)行情況來看,DCS較好地實(shí)現(xiàn)了其控制功能,并發(fā)揮了安全經(jīng)濟(jì)、使用可靠的優(yōu)點(diǎn),取得了良好的效果,而電氣控制仍然采用較常規(guī)的控制手段,使用盤臺(tái)上一對(duì)一硬手操方式。隨著計(jì)算機(jī)的快速發(fā)展和控制技術(shù)的不斷提高,使得機(jī)爐控制與電氣控制日益顯得不協(xié)調(diào),控制水平也逐漸拉大。為了解決這一矛盾,有效的辦法就是將電氣納入DCS控制之中,這樣既利用DCS已成熟的分散控制技術(shù),又能提高電氣控制水平。電氣控制納入DCS以后,可充分利用DCS的手段,使電氣防誤操作等功能實(shí)現(xiàn)更方便、更完備,并且將相關(guān)量的顯示報(bào)警與電氣設(shè)備的控制調(diào)節(jié)有機(jī)地結(jié)合起來,有效提高整個(gè)電氣控制的安全性和可靠性。
1997年7月原電力部召開了熱工自動(dòng)化領(lǐng)導(dǎo)小組第六次擴(kuò)大會(huì),對(duì)電氣設(shè)計(jì)如何與DCS配合提出了具體意見:“實(shí)現(xiàn)爐、機(jī)、電集中管理,使電廠主控室爐、機(jī)、電控制水平協(xié)調(diào)發(fā)展是必要的而且在現(xiàn)有技術(shù)和裝備條件下是可行的,可以起到省人、省主控制室面積,便于集控值班運(yùn)行的作用,而且不提高造價(jià)。領(lǐng)導(dǎo)小組要求以積極的態(tài)度加入電氣納入DCS的工程試點(diǎn)?!卑创司?,九江電廠三期2×350MW、信陽電廠一期2×300MW、益陽電廠一期2×300MW工程電氣系統(tǒng)均納入DCS監(jiān)控?,F(xiàn)依據(jù)這幾個(gè)工程中具體實(shí)施的過程和要求,就電氣系統(tǒng)納入DCS監(jiān)控的一些有關(guān)問題進(jìn)行分析和探討。電氣系統(tǒng)與熱工自動(dòng)化相比在控制要求及運(yùn)行過程中有著很多不同點(diǎn),電氣的主要特點(diǎn)表現(xiàn)為:
(1)電氣設(shè)備相對(duì)熱工設(shè)備而言控制對(duì)象少,操作頻率低,有的系統(tǒng)或設(shè)備運(yùn)行正常時(shí),時(shí)常幾個(gè)月或更長時(shí)間才操作一次。
(2)電氣設(shè)備保護(hù)自動(dòng)裝置要求可靠性高,動(dòng)作速度快。發(fā)變組保護(hù)動(dòng)作速度要求在40ms以內(nèi);自動(dòng)準(zhǔn)同期采用同步電壓方式,轉(zhuǎn)速、電壓調(diào)整和滑壓控制要求在5ms以內(nèi);電壓自動(dòng)調(diào)整裝置快速勵(lì)磁要求時(shí)間極短;廠用電快切裝置快速切換時(shí)間一般小于60~80ms,同步鑒定相位差5°~20°。
(3)300MW及以上機(jī)組一般每2臺(tái)機(jī)組共用1臺(tái)起/備變,任一機(jī)組檢修都不能影響另1臺(tái)機(jī)組的正常運(yùn)行,因此DCS控制應(yīng)考慮其控制方式,確保只能有1臺(tái)機(jī)組的DCS實(shí)現(xiàn)對(duì)共用部分的控制,同時(shí)另一機(jī)組DCS能夠?qū)崿F(xiàn)實(shí)時(shí)監(jiān)視,并且這種操作控制權(quán)能實(shí)現(xiàn)切換。
(4)電氣設(shè)備電氣系統(tǒng)的聯(lián)鎖邏輯較簡單,但電氣設(shè)備本身操作機(jī)構(gòu)復(fù)雜。
因此,機(jī)組的電氣系統(tǒng)納入DCS控制,要求控制系統(tǒng)具有很高的可靠性。除了能實(shí)現(xiàn)正常起停和運(yùn)行操作外,尤其要求能夠?qū)崿F(xiàn)實(shí)時(shí)顯示異常運(yùn)行和事故狀態(tài)下的各種數(shù)據(jù)和狀態(tài),并提供相應(yīng)的操作指導(dǎo)和應(yīng)急處理措施,保證電氣系統(tǒng)自動(dòng)控制在最安全合理的工況下工作。

選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個(gè)大概,以便學(xué)習(xí)編程時(shí)查找);
2、由位控邏輯入手,逐漸增加定時(shí)、計(jì)數(shù)等條件,把或、與、非關(guān)系理順;
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個(gè)物理回路驗(yàn)證,比如變頻器+電機(jī)+測速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時(shí)也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學(xué)會(huì)一種至于其它的學(xué)習(xí)起來也就簡單了。
