I中文摘要A320飞机是欧洲空中客车工业公司研制的双发单通道中短程客机,由于它是世界上第一种采用电传操纵和侧杆驾驶的亚音速民用客机,因此该机对供电系统比较严格,加强对电源系统的研究十分必要。飞机电源系统是机载电气设备的一个重要组成部分,它的作用是向飞机上的所有用电设备供电。恒速恒频交流电源(CSCF)是一种较先进的机载电源,是大型喷气式飞机上常采用的电源型式,也是电力电子技术在该领域的成功应用。如B747,B757,A320等大型客机上采用的都是恒速恒频交流电源系统。恒速恒频电源主要采用了组合驱动发电机,微处理器式发电机控制保护组件及汇流条功率控制组件,使其具有重量较轻、体积小、可靠性高等优点;此外,由于控制组件采用了模块式设计,并具有机内自检功能,使维修性得到改善。对民用航空器机务维修人员来说,加强对飞机电源系统的认识和研究将有助于快速准确地排除飞机故障。该选题具有重要的现实意义。本论文主要介绍了A320飞机电源系统中的交流电源部分,全文共分六大部分:绪论,恒速恒频交流电源系统,主交流电源,辅助交流电源,外电源,应急交流电源,电源系统主控制面板简介和交流电源系统故障分析。其中主要阐述了作为交流电源系统核心部件的组合驱动发电机IDG的简单原理和工作过程,发电机控制组件GCU的控制与保护,以及应急状态下飞机交流电源系统的工作情况。最后,针对A320飞机交流电源系统常见或可能的故障进行了分析并提供了排除办法。并用Simulink软件对航空静止变流器逆变部分模拟仿真。关键词:电源恒速恒频发电机故障维护仿真IIThispaperA320aircraftisEurope'sAirbusIndustriedevelopedshort-rangetwin-engineaircraftinasinglechannel,becauseitisusingtheworld'sfirstfly-roddrivingandsidesubsoniccivilaircraft,aircraftpowersupplysystemandthereforemorestringentstrengthenResearchonthepowersystemisnecessary.Aircraftpowersystemisanimportantpartoftheonboardelectricalequipment,itsroleistosupplyalltheelectricalequipmentontheaircraft.ConstantspeedconstantfrequencyACpowersupply(CSCF)isamoreadvancedairbornepower,isoftenusedonlargejetpowertype,butalsothesuccessfulapplicationofpowerelectronicstechnologyinthefield.SuchastheuseoftheB747,B757,A320andotherlargeaircraftareconstantspeedconstantfrequencyACpowersystem.Constantspeedconstantfrequencypowersupplyusesacombinationofmainlydrivengenerators,microprocessor-controlledgeneratorbusbarprotectioncomponentsandpowercontrolmodule,ithasalightweight,smallsize,highreliability。Inaddition,sincethecontrolmoduleusesamodulardesign,andhasaself-testfunctionwithinthemachine,sothatmaintenancecanbeimproved.Forcivilaircraftmaintenancepersonnel,thestrengtheningoftheaircraftpowersystemawarenessandresearchwillhelptoquicklyandaccuratelyexcludeaircraftmalfunction.Thetopichasimportantpracticalsignificance.ThispaperwillintroducestheA320aircraftpowersystemACpowersection,thetextisdividedintosixparts:introduction,constantspeedconstantfrequencyACpowersystem,themainACpowersupply,auxiliaryACpowersupply,externalpowersupply,emergencyACpower,thepowersystemmastercontrolPanelOverviewandACpowersystemfaultanalysis.MainlydescribesthesystemasacorecomponentoftheACgeneratordrivenIDGcombinationofsimpleprinciplesandworkprocesses,controlandprotectionofthegeneratorcontrolunitGCU,andtheworkoftheaircraftunderthestateofemergencyACpowersystem.Finally,theA320fortheACpowersupplysystemormaybeacommonfaultanalysisandprovidesawaytoexclude.AndaviationstaticinverterinverterpartsimulationusingSimulinksoftware.Keywords::PowerCSCFGeneratorFaultmaintainsimulationIII目录第一章绪论......................................................................................................
