3．觀察是否一直報(bào)警還是偶爾出現(xiàn)報(bào)警，如果是一直報(bào)警則是單元或是控制板故障，否則可能是電機(jī)。

DCS和PLC在火電廠的應(yīng)用在火電廠熱工自動(dòng)化領(lǐng)域，DCS和PLC是兩個(gè)完全不同而又有著千絲萬(wàn)縷聯(lián)系的概念。DCS和PLC都是計(jì)算機(jī)技術(shù)與工業(yè)控制技術(shù)相結(jié)合的產(chǎn)物，火電廠主機(jī)控制系統(tǒng)用的是DCS，而PLC主要應(yīng)用在電廠輔助車間。DCS和PLC都有操作員站提供人機(jī)交互的手段、都依靠基于計(jì)算機(jī)技術(shù)的控制器完成控制運(yùn)算、都通過I/O卡件完成與一次元件和執(zhí)行裝置的數(shù)據(jù)交換、都具備稱之為網(wǎng)絡(luò)的通信系統(tǒng)。隨著國(guó)內(nèi)電廠裝機(jī)容量的不斷擴(kuò)大及電力系統(tǒng)改革的推進(jìn)，對(duì)輔助車間控制的要求也不斷提高，在這個(gè)大環(huán)境，DCS系統(tǒng)進(jìn)入輔助車間控制已成為趨勢(shì)。

為了保障變頻器的安全運(yùn)行，避免變頻器受負(fù)載沖擊，必須做好以下幾點(diǎn):㈠盡量保證變頻器有充足的加減速時(shí)間變頻器在開機(jī)或升速時(shí)，自身有軟起動(dòng)功能；關(guān)機(jī)或減速時(shí)，自身有軟關(guān)斷功能。在設(shè)備允許的范圍內(nèi)，盡量增加加減速時(shí)間。當(dāng)設(shè)備要求有較短的加減速時(shí)間時(shí)，變頻器應(yīng)采取以下措施:加減速時(shí)間由變頻器容量和負(fù)載來決定。負(fù)荷越重，變頻器容量越小，加減速時(shí)間設(shè)定應(yīng)越長(zhǎng)。短的加減速時(shí)間是由變頻器的容量決定的。假若運(yùn)行過程中沖擊電流在允許時(shí)間內(nèi)超過變頻器的額定電流，則必須增加變頻器的容量。

1 TG報(bào)警（TG紅燈點(diǎn)亮） 失速或暴走，即電機(jī)的速度不按指令走，所以，從指令到速度反饋一路，都有可能出故障。 1． 單軸可通過互換單元，雙軸將各軸指令線和動(dòng)力線互換，來初步判斷是否為控制單元還是電機(jī)故障，一般是單元的可能性大。 2． 如果上電就報(bào)警，則有可能是主回路晶體管壞了�？捎萌f(wàn)用表測(cè)量并自行更換晶體管模塊，如果是高速報(bào)警而低速正常則可能是控制板或電機(jī)有問題，這也可通過交換伺服單元來判別。
繼電保護(hù)狀態(tài)檢修的問題分析繼電保護(hù)狀態(tài)檢修工作實(shí)施中，由于受到各種因素的影響，在實(shí)際中就存在著一些問題。在對(duì)二次回路監(jiān)測(cè)問題上要加強(qiáng)重視。在計(jì)算機(jī)的智能化發(fā)展下，對(duì)繼電保護(hù)裝置的自身狀態(tài)監(jiān)測(cè)提供了技術(shù)支持，大大提高了監(jiān)測(cè)的質(zhì)量和效率。而在面對(duì)相對(duì)比較復(fù)雜的二次回路的時(shí)候，就會(huì)涉及到很多設(shè)備和繼電器，由于接點(diǎn)的分散化，這就使得在監(jiān)測(cè)過程中，保護(hù)裝置存在線路中斷以及結(jié)構(gòu)內(nèi)部零件的老化問題，影響了狀態(tài)檢測(cè)的效率。
