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

n.改正，修正correctionFlexibleACTransmissionSystem說(shuō)明這是一個(gè)典型的英文長(zhǎng)句。翻譯是要注意整個(gè)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(jì)人員用于并聯(lián)無(wú)功補(bǔ)償，要么在輸電級(jí)用于電壓調(diào)整和系統(tǒng)穩(wěn)定性改善，要么在配電級(jí)用于電壓調(diào)整、功率因數(shù)校正和/或電能質(zhì)量的改善。FlexibleACTransmissionSystem6.AswithallstaticFACTSdevicestheSTATCOMhasthepotentialtobeexceptionallyreliablebutwithaddedcapabilityto…嘗試翻譯6.AswithallstaticFACTSdevicestheSTATCOMhasthepotentialtobeexceptionallyreliablebutwithaddedcapabilityto…生詞adv.極其，非常exceptionally翻譯STATCOM在和所有靜態(tài)FACTS設(shè)備一樣具有異常可靠的潛能的同時(shí)，此外還有……的能力。FlexibleACTransmissionSystem說(shuō)明句首的Aswith表示“和……一樣，與……一致”。but表示“除……之外，此外”。注意：千萬(wàn)不能把withall看作一體，譯為“盡管”，更不能but把譯為“但是”。本課程參考教材：朱永強(qiáng)《電力專業(yè)英語(yǔ)閱讀與翻譯》機(jī)械工業(yè)出版社2024-06電力專業(yè)英語(yǔ)(22)PowerQualityandItsImprovement參考教材：朱永強(qiáng).電力專業(yè)英語(yǔ)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(wú)關(guān)。生詞n.
