电磁的electromagneticn.差异，偏差deviationPowerQualityandItsImprovement说明词组isequivalentto表示“相等[当]于...,等(同)于,与...等效”。originatinginorconductedthroughthepowersystem是省略写法，补全应为：originatinginthepowersystemorconductedthroughthepowersystem。PowerQualityandItsImprovement2.Thecompatibilitylevelischosensuchthatcompatibilityisachievedformostequipmentmostofthetime:typically95%ofequipmentof95%ofthetime.尝试翻译2.Thecompatibilitylevelischosensuchthatcompatibilityisachievedformostequipmentmostofthetime:typically95%ofequipmentof95%ofthetime.生词n.

共存，和睦相处compatibility翻译兼容性水平选的是大多数设备在大部分时间里达到的兼容性：典型地取95％时间的95％的设备。PowerQualityandItsImprovement说明词组suchthat表示“如此，这样”。在这里equipment是不可数名词。PowerQualityandItsImprovement3.Herethesurgeprotectionisreferredmainlytolightningshielding,namelytodischargethepulseenergyinducedbylightingshocksinveryshorttimeinordertoprotecttheentiredevice.尝试翻译3.Herethesurgeprotectionisreferredmainlytolightningshielding,namelytodischargethepulseenergyinducedbylightingshocksinveryshorttimeinordertoprotecttheentiredevice.生词v.释放

n.放电discharge

翻译浪涌保护主要指防雷保护，就是在极短的时间内释放掉设备电流上因感应雷击而产生的大量脉冲能量到安全地线上，从而保护整个设备。n.浪涌保护，过(高峰)电压保护surgeprotection

PowerQualityandItsImprovement说明bereferredto表示“是指，指的是”。namely表示“即，也就是”PowerQualityandItsImprovement4.Fastresponseisthebasicrequirementforasuppresser;otherwise,harmwillalreadycomeforthbeforetheactionofthesuppresserifafastincreasinginstantaneouspeakvoltageappearsacrosstheprotectedcircuit.尝试翻译4.Fastresponseisthebasicrequirementforasuppresser;otherwise,harmwillalreadycomeforthbeforetheactionofthesuppresserifafastincreasinginstantaneouspeakvoltageappearsacrosstheprotectedcircuit.生词n.

抑制器suppresser翻译对抑制器的基本要求是反应速度要快，否则，如果在受保护电路的两端出现上升速度极快的瞬时峰值电压，那么在抑制器作用之前就会出现危害。n.

出现，涌现comeforthPowerQualityandItsImprovement5.It’svaluabletosimulatethespikescomingforthonthepowersystemcausedbylightningandnuclearexplosionandtoimposethemondevicesundertesttoensurenomalfunctionordegradationofcapabilitywilloccur.尝试翻译5.It’svaluabletosimulatethespikescomingforthonthepowersystemcausedbylightningandnuclearexplosionandtoimposethemondevicesundertesttoensurenomalfunctionordegradationofcapabilitywilloccur.生词n.

故障malfunctionn.降级，降格，退化degradationn.

尖峰信号spikePowerQualityandItsImprovement说明词组imposeon表示“施加于”。undertest表示“测试中的，被测的”。翻译模拟因雷电和核爆炸在电网上生成的尖峰信号并施加在实验设备上，以保证不会导致设备的性能下降或故障，是有价值的。本课程参考教材：朱永强《电力专业英语阅读与翻译》机械工业出版社2024-06电力专业英语(24)RenewableEnergySourcesandDistributedGeneration参考教材：朱永强.电力专业英语阅读与翻译.机械工业出版社，2024-06PowerQualityandItsImprovement1.Todiscovernewsourcesofenergy,toobtainanessentiallyinexhaustiblesupplyofenergyforthefuture,tomakeenergyavailablewhereverneeded,andtoconvertenergyfromoneformtoanotheranduseitwithoutcreatingthepollutionwhichwilldestroyourbiosphereareamongthegreatestchallengesfacingthisworldtoday.尝试翻译1.Todiscovernewsourcesofenergy,toobtainanessentiallyinexhaustiblesupplyofenergyforthefuture,tomakeenergyavailablewhereverneeded,andtoconvertenergyfromoneformtoanotheranduseitwithoutcreatingthepollutionwhichwilldestroyourbiosphereareamongthegreatestchallengesfacingthisworldtoday.生词adj.

无穷尽的，用不完的inexhaustiblen.生物圈biospherePowerQualityandItsImprovement说明句中availablewhereverneeded意思是“哪里需要哪里就可以得到”。词组convert…from…to表示“由…转换为…”。among表示“在…中，是…中之一”。翻译发现新能源，得以在将来提供本质上用之不竭的能量供应，使能源随用随有，并且把能量从一种形式转换为另一种形式以及使用时不产生会破坏我们生物圈的污染，这是如今世界所面临的最大挑战之一。PowerQualityandItsImprovement2.Fossilfuelsarenonrenewable,thatis,theydrawonfiniteresourcesthatwilleventuallydwindle,becomingtooexpensiveortooenvironmentallydamagingtoretrieve.尝试翻译2.Fossilfuelsarenonrenewable,thatis,theydrawonfiniteresourcesthatwilleventuallydwindle,becomingtooexpensiveortooenvironmentallydamagingtoretrieve.生词adj.

不可再生的，不可更新的nonrenewablev.缩小dwindle翻译化石燃料是不可再生的，也就是说，它们利用的是最终会减少、变得过于昂贵或太破坏环境而无法重新获取的有限资源。v.重新得到retrievePowerQualityandItsImprovement说明词组thatis表示“即，就是，也就是说”。词组too…to…表示“太……以至不能”。PowerQualityandItsImprovement3.Wehaveusedbiomassenergyor"bioenergy"—theenergyfromplantsandplant-derivedmaterials—sincepeoplebeganburningwoodtocookfoodandkeepwarm.尝试翻译3.Wehaveusedbiomassenergyor"bioenergy"—theenergyfromplantsandplant-derivedmaterials—sincepeoplebeganburningwoodtocookfoodandkeepwarm.生词n.生物质，用作能源的植物材料biomass

翻译自从人们开始烧柴来做饭和取暖，我们就在使用生物质能或“生物能源”——来自于植物或其提取物的能量。n.生物能bioenergy

氢hydrogen翻译氢相对其重量而言能量很高，但相对其体积则能量很低，因此需要新的技术来存储和输送它。PowerQualityandItsImprovement说明for在此表示“对应于，相对于”。PowerQualityandItsImprovement5.OTECworksbestwhenthetemperaturedifferencebetweenthewarmer,toplayeroftheoceanandthecolder,deepoceanwaterisabout20°C(36°F).尝试翻译5.OTECworksbestwhenthetemperaturedifferencebetweenthewarmer,toplayeroftheoceanandthecolder,deepoceanwaterisabout20°C(36°F).生词n.

温度，气温temperature

翻译当温暖的海洋表层和较冷的深层海水之间温差约为摄氏20度（华氏36度）时，OTEC效果最好。PowerQualityandItsImprovement说明不要被句中的逗号迷惑，逗号所分隔的是同一主体的多个定语。PowerQualityandItsImprovement6.Theseconditionsexistintropicalcoastalareas,roughlybetweentheTropicofCapricornandtheTropicofCancer.尝试翻译6.Theseconditionsexistintropicalcoastalareas,roughlybetweentheTropicofCapricornandtheTropicofCancer.生词adj.热带的tropical翻译这些情况大概出现在介于南回归线和北回归线之间的热带海岸区。n.摩羯宫，摩羯(星)座Capricornn.巨蟹星座CancerPowerQualityandItsImprovement说明roughlybetween引领的短语作为tropicalcoastalareas的状语。Tropic是“回归线”，Capricorn指的是“摩羯星座”，Cancer指的是“巨蟹星座”，基于两个星座在天球上的位置，TropicofCapricorn和theTropicofCancer分别对应“南回归线”和“北回归线”。PowerQualityandItsImprovement7.Theyare"distributed"becausetheyareplacedatornearthepointofenergyconsumption,unliketrad
