電力專業(yè)英語(22)PowerQualityandItsImprovement參考教材：朱永強(qiáng).電力專業(yè)英語閱讀與翻譯.機(jī)械工業(yè)出版社，2024-06PowerQualityandItsImprovement1.Notethatpowerqualityhasnothingtodowithdeviationsoftheproductofvoltageandcurrent(thepower)fromanyidealshape.嘗試翻譯1.Notethatpowerqualityhasnothingtodowithdeviationsoftheproductofvoltageandcurrent(thepower)fromanyidealshape.翻譯注意，電能質(zhì)量和電壓、電流乘積（功率）與任何理想形態(tài)的偏差無關(guān)。生詞n.

電能質(zhì)量powerqualityn.差異，偏差deviationPowerQualityandItsImprovement說明hasnothingtodowith表示“與……無關(guān)”。product意思是“乘積”，在此不能譯為“產(chǎn)生”。deviationfromidealshape表示“與理想形態(tài)的偏差”。PowerQualityandItsImprovement2.Thebranchcurrentiscontrolledbyphaseanglecontrolofthefiringpulsestothethyristors,thatis,thevoltageacrossthereactorsisthefullsystemvoltageat90degreesfiringangleandzeroat180degrees.嘗試翻譯2.Thebranchcurrentiscontrolledbyphaseanglecontrolofthefiring

點火脈沖firing

pulsen.半導(dǎo)體閘流管thyristor翻譯通過對晶閘管點火脈沖的相角控制來控制支路電流，即，電抗器上的壓降在點火角為90度時為全部系統(tǒng)電壓，在180度時為零。PowerQualityandItsImprovement說明thatis表示“即，換句話說，就是說”。thatis后面的句子有詞語省略，補(bǔ)全應(yīng)為：…thevoltageacrossthereactorsisthefullsystemvoltageat90degreesfiringangleandiszeroat180degreesfiringangle.PowerQualityandItsImprovement3.Thecapacitorswitching(connecting)takesplaceatthatspecificinstantinacycleatwhichtheconditionsforminimumtransientsaresatisfied,thatis,whenthevoltageacrossthethyristorvalveiszeroorminimum.嘗試翻譯3.Thecapacitorswitching(connecting)takesplaceatthatspecificinstantinacycleatwhichtheconditionsforminimumtransientsaresatisfied,thatis,whenthevoltageacrossthethyristorvalveiszeroorminimum.生詞adj.轉(zhuǎn)瞬即逝的

n.瞬變transient

翻譯電容投切（連接）發(fā)生在一個周期中的特定時刻，此時的最小暫態(tài)現(xiàn)象令人滿意，即，晶閘管閥上的壓降為零或最小的時候。PowerQualityandItsImprovement說明atwhich引導(dǎo)的定語從句修飾specificinstant。atthatinstantatwhich與when的含義接近，都表示發(fā)生的時刻，引導(dǎo)時間狀語從句，這兩個狀語從句是并列關(guān)系。PowerQualityandItsImprovement4.TheresponsetimeofSVCsisintherangeof2-3cycleswhichmakesSVCswellsuitedforapplicationsinwhichfastandrepetitivecontrolofreactivepowerisrequired.嘗試翻譯4.TheresponsetimeofSVCsisintherangeof2-3cycleswhichmakesSVCswellsuitedforapplicationsinwhichfastandrepetitivecontrolofreactivepowerisrequired.生詞adj.

重復(fù)的，反復(fù)性的repetitive翻譯SVC的響應(yīng)時間在2-3個周期的范圍內(nèi)，使其很適合用在需要無功功率的快速、重復(fù)控制的應(yīng)用中。PowerQualityandItsImprovement說明intherangeof表示“在…范圍內(nèi)”。which和inwhich引導(dǎo)的定語從句，分別修飾therangeof2-3cycles和applications。PowerQualityandItsImprovement5.TheStaticSynchronousCompensator(STATCOM)isaprincipalstate-of-the-artFACTSequipmentandisnowacommerciallyavailableadditionaltoolforusebysystemplannersanddesignersforshuntreactivepowercompensationateitherthetransmissionlevelforvoltageregulationandsystemstabilityimprovementoratthedistributionlevelforvoltageregulation,powerfactorcorrectionand/orimprovementofpowerquality.嘗試翻譯5.TheStaticSynchronousCompensator(STATCOM)isaprincipalstate-of-the-artFACTSequipmentandisnowacommerciallyavailableadditionaltoolforusebysystemplannersanddesignersforshuntreactivepowercompensationateitherthetransmissionlevelforvoltageregulationandsystemstabilityimprovementoratthedistributionlevelforvoltageregulation,powerfactorcorrectionand/orimprovementofpowerquality.生詞adj.

達(dá)到最新技術(shù)發(fā)展水平的state-of-the-art

n.改正，修正correctionPowerQualityandItsImprovement說明這是一個典型的英文長句。翻譯是要注意整個句子的通順流暢。state-of-the-art意思是“達(dá)到最新技術(shù)發(fā)展水平的”。句式表示“要么…，要么…”，或“或者…或者…”。翻譯靜止同步補(bǔ)償器（STATCOM）是重要的、達(dá)到最新發(fā)展水平的FACTS設(shè)備，現(xiàn)在作為可用的額外工具被系統(tǒng)規(guī)劃和設(shè)計人員用于并聯(lián)無功補(bǔ)償，要么在輸電級用于電壓調(diào)整和系統(tǒng)穩(wěn)定性改善，要么在配電級用于電壓調(diào)整、功率因數(shù)校正和/或電能質(zhì)量的改善。PowerQualityandItsImprovement6.AswithallstaticFACTSdevicestheSTATCOMhasthepotentialtobeexceptionallyreliablebutwithaddedcapabilityto…嘗試翻譯6.AswithallstaticFACTSdevicestheSTATCOMhasthepotentialtobeexceptionallyreliablebutwithaddedcapabilityto…生詞adv.極其，非常exce
