电力专业英语阅读与翻译 课件 15-Stability of Power System

电力专业英语(15)StabilityofPowerSystem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，2024-06BasicConceptsofElectricPowerSystem1.Powersystemstabilitymaybebroadlydefinedasthatpropertyofapowersystemthatenablesittoremaininastateofoperatingequilibriumundernormaloperatingconditionsandtoregainanacceptablestateofequilibriumafterbeingsubjectedtoadisturbance.尝试翻译1.Powersystemstabilitymaybebroadlydefinedasthatpropertyofapowersystemthatenablesittoremaininastateofoperatingequilibriumundernormaloperatingconditionsandtoregainanacceptablestateofequilibriumafterbeingsubjectedtoadisturbance.生词n.

电，电学，电流equilibriumv.

产生，发生regain

翻译电力系统稳定性可以广泛定义为电力系统的一个特性，即在正常工作条件下保持运行平衡状态，在受到干扰以后可以重新回到可接受的平衡状态。disturbance

v.

产生，发生BasicConceptsofElectricPowerSystem说明在类似定义等表述语句中，往往说明的主体带有很长的定语，而且定语的结构可能还比较复杂。在翻译时，为了避免拗口，可以将定语部分转换为单独的句子来翻译，只要在原来的主体和定语部分之间建立适当的联系即可。BasicConceptsofElectricPowerSystem2.Sincepowersystemsrelyonsynchronousmachinesforgenerationofelectricalpower,anecessaryconditionforsatisfactorysystemoperationisthatallsynchronousmachinesremaininsynchronismor,colloquially,“instep.”尝试翻译2.Sincepowersystemsrelyonsynchronousmachinesforgenerationofelectricalpower,anecessaryconditionforsatisfactorysystemoperationisthatallsynchronousmachinesremaininsynchronismor,colloquially,“instep.”生词adj.

同步的；共时的

synchronousn.

同步性synchronism

翻译既然电力系统依靠同步电机发电，系统正常运行的一个必要条件是所有的同步电机保持同步，通俗一点讲就是“步调一致”。BasicConceptsofElectricPowerSystem说明insynchronism和instep都可以表示“同步”，前者为比较专业的用法，后者通俗一些。BasicConceptsofElectricPowerSystem3.Althoughthethreecategoriesareconcernedwithdifferentaspectsofthestabilityproblem,intermsofanalysisandsimulationtheyarereallyextensionsofoneanotherwithoutclearlyboundaries.尝试翻译翻译尽管在分析和仿真中这三个类别涉及稳定性问题的不同方面，它们确实是彼此没有明确界限的范围。生词boundaryn.

边界；界限；分界线3.Althoughthethreecategoriesareconcernedwithdifferentaspectsofthestabilityproblem,intermsofanalysisandsimulationtheyarereallyextensionsofoneanotherwithoutclearlyboundaries.BasicConceptsofElectricPowerSystem说明词组beconcernedwith原意是“干预，参与”，在此表示“涉及，关注”。intermsof表示“在……方面”。oneanother意思是“彼此之间”，修饰后面的without短语。BasicConceptsofElectricPowerSystem4.Themechanismbywhichinterconnectedsynchronousmachinesmaintainsynchronismwithoneanotheristhroughrestoringforces,whichactwheneverthereareforcestendingtoaccelerateordecelerateoneormoremachineswithrespecttoothermachines.尝试翻译4.Themechanismbywhichinterconnectedsynchronousmachinesmaintainsynchronismwithoneanotheristhroughrestoringforces,whichactwheneverthereareforcestendingtoaccelerateordecelerateoneormoremachineswithrespecttoothermachines.生词v.

减速；(使)减缓decelerate

翻译相联的同步电机彼此保持同步的机理是利用回复力，当有一台或多台电机在外力作用下相对于其它电机加速或减速运转时，回复力起作用。BasicConceptsofElectricPowerSystem说明句子的主干是Themechanismisthroughrestoringforces。其中主语mechanism带有一个由bywhich引导的定语从句，而restoringforce带有一个由which引导的定语从句，该定语从句中还含有一个由whenever引导的时间状语从句。词组withrespectto在此表示“相对于……”。BasicConceptsofElectricPowerSystem5.InNorthAmericanliterature,ithasbeenusedmostlytodenotesmall-signalstabilityinthepresenceofautomaticcontroldevices(primarilygeneratorvoltageregulators)asdistinctfromtheclassicalsteady-statestabilitywithoutautomaticcontrols.尝试翻译5.InNorthAmericanliterature,ithasbeenusedmostlytodenotesmall-signalstabilityinthepresenceofautomaticcontroldevices(primarilygeneratorvoltageregulators)asdistinctfromtheclassicalsteady-statestabilitywithoutautomaticcontrols.生词adj.

不同的；明显的dist
