電，電學，電流equilibriumv.

產(chǎn)生，發(fā)生regain

翻譯電力系統(tǒng)穩(wěn)定性可以廣泛定義為電力系統(tǒng)的一個特性，即在正常工作條件下保持運行平衡狀態(tài)，在受到干擾以后可以重新回到可接受的平衡狀態(tài)。disturbance

v.

產(chǎn)生，發(fā)生BasicConceptsofElectricPowerSystem說明在類似定義等表述語句中，往往說明的主體帶有很長的定語，而且定語的結構可能還比較復雜。在翻譯時，為了避免拗口，可以將定語部分轉換為單獨的句子來翻譯，只要在原來的主體和定語部分之間建立適當?shù)穆?lián)系即可。BasicConceptsofElectricPowerSystem2.Sincepowersystemsrelyonsynchronousmachinesforgenerationofelectricalpower,anecessaryconditionforsatisfactorysystemoperationisthatallsynchronousmachinesremaininsynchronismor,colloquially,“instep.”嘗試翻譯2.Sincepowersystemsrelyonsynchronousmachinesforgenerationofelectricalpower,anecessaryconditionforsatisfactorysystemoperationisthatallsynchronousmachinesremaininsynchronismor,colloquially,“instep.”生詞adj.

同步的；共時的

synchronousn.

同步性synchronism

翻譯既然電力系統(tǒng)依靠同步電機發(fā)電，系統(tǒng)正常運行的一個必要條件是所有的同步電機保持同步，通俗一點講就是“步調(diào)一致”。BasicConceptsofElectricPowerSystem說明insynchronism和instep都可以表示“同步”，前者為比較專業(yè)的用法，后者通俗一些。BasicConceptsofElectricPowerSystem3.Althoughthethreecategoriesareconcernedwithdifferentaspectsofthestabilityproblem,intermsofanalysisandsimulationtheyarereallyextensionsofoneanotherwithoutclearlyboundaries.嘗試翻譯翻譯盡管在分析和仿真中這三個類別涉及穩(wěn)定性問題的不同方面，它們確實是彼此沒有明確界限的范圍。生詞boundaryn.

邊界；界限；分界線3.Althoughthethreecategoriesareconcernedwithdifferentaspectsofthestabilityproblem,intermsofanalysisandsimulationtheyarereallyextensionsofoneanotherwithoutclearlyboundaries.BasicConceptsofElectricPowerSystem說明詞組beconcernedwith原意是“干預，參與”，在此表示“涉及，關注”。intermsof表示“在……方面”。oneanother意思是“彼此之間”，修飾后面的without短語。BasicConceptsofElectricPowerSystem4.Themechanismbywhichinterconnectedsynchronousmachinesmaintainsynchronismwithoneanotheristhroughrestoringforces,whichactwheneverthereareforcestendingtoaccelerateordecelerateoneormoremachineswithrespecttoothermachines.嘗試翻譯4.Themechanismbywhichinterconnectedsynchronousmachinesmaintainsynchronismwithoneanotheristhroughrestoringforces,whichactwheneverthereareforcestendingtoaccelerateordecelerateoneormoremachineswithrespecttoothermachines.生詞v.

減速；(使)減緩decelerate

翻譯相聯(lián)的同步電機彼此保持同步的機理是利用回復力，當有一臺或多臺電機在外力作用下相對于其它電機加速或減速運轉時，回復力起作用。BasicConceptsofElectricPowerSystem說明句子的主干是Themechanismisthroughrestoringforces。其中主語mechanism帶有一個由bywhich引導的定語從句，而restoringforce帶有一個由which引導的定語從句，該定語從句中還含有一個由whenever引導的時間狀語從句。詞組withrespectto在此表示“相對于……”。BasicConceptsofElectricPowerSystem5.InNorthAmericanliterature,ithasbeenusedmostlytodenotesmall-signalstabilityinthepresenceofautomaticcontroldevices(primarilygeneratorvoltageregulators)asdistinctfromtheclassicalsteady-statestabilitywithoutautomaticcontrols.嘗試翻譯5.InNorthAmericanliterature,ithasbeenusedmostlytodenotesmall-signalstabilityinthepresenceofautomaticcontroldevices(primarilygeneratorvoltageregulators)asdistinctfromtheclassicalsteady-statestabilitywithoutautomaticcontrols.生詞adj.

不同的；明顯的dist
