亚威小区配电系统工程设计摘要：在国家城镇化的战略上，许多地区开始进行住宅楼的开发和建设，住宅小区的供配电系统作为终端供电的基础，关系到居民的日常生活。因此对住宅小区的供配电设计和建设必须要依靠国家规定的供配电安全性能、稳定性能、可靠性能等标准进行设计。本设计主要对亚威小区进行供配电设计，按照国家规定的相关设计规范，对亚威小区的供配电负荷进行详细分析，按照负荷等级进行划分，准确计算各个住宅楼的负荷数据。本小区从外部电源供电，电压等级为10kV，为小区供电电压为0.4kV。通过计算的负荷数据完成变压器的选型，对变压器的容量和数量以及具体型号进行分析。按照具体亚威小区的布局，对电气主接线进行选择，电气主接线的合理选择是后期短路电流计算和设备选择的基本依据。通过CAD制图完成电气主接线的图纸设计。在设备选型中，考虑基本选型计算方法以及校验思路，保证设备选型达到亚威小区的供配电需求。在防雷接地保护设计中，考虑亚威小区的具体地理情况。亚威小区的供配电系统工程设计，满足设计的经济合理性以及系统稳定灵活的基本要求。关键词：小区供配电；负荷计算；短路电流；防雷接地Abstract:Inthenationalurbanizationstrategy,manyareasbegantodevelopandconstructresidentialbuildings.Asthebasisofterminalpowersupply,thepowersupplyanddistributionsystemofresidentialquartersisrelatedtothedailylifeofresidents.Therefore,thedesignandconstructionofpowersupplyanddistributioninresidentialdistrictsmustrelyonthenationalstandardsofpowersupplyanddistributionsafety,stabilityandreliability.ThisdesignmainlycarriesonthepowersupplyanddistributiondesignofYaweiDistrict.Accordingtotherelevantdesignspecificationsstipulatedbythestate,thepowersupplyanddistributionloadofYaweiDistrictisanalyzedindetail,andtheloaddataofeachresidentialbuildingiscalculatedaccuratelyaccordingtotheloadgrade.Theselectionoftransformeriscompletedbycalculatingloaddata,andthecapacityandquantityoftransformerandthespecificmodelareanalyzed.AccordingtothespecificlayoutofYaweiDistrict,theselectionofmainelectricalwiringisthebasicbasisforthecalculationofshortcircuitcurrentandequipmentselectioninthelaterperiod.Intheequipmentselection,thebasicselectioncalculationmethodandcheckingideaareconsideredtoensurethattheequipmentselectionmeetsthedemandofpowersupplyanddistributioninYaweiDistrict.Inthedesignoflightningprotectiongroundingprotection,thespecificgeographicalconditionsofYaweiDistrictareconsidered.ThedesignofpowersupplyanddistributionsysteminYaweiDistrictmeetsthebasicrequirementsofeconomicrationalityandstabilityandflexibilityofthesystem.Keywords:districtpowersupplyanddistribution;loadcalculation;shortcircuitcurrent;lightningprotectiongrounding目录1绪论....................................................................11.1住宅小区供配电系统现状及研究意义...................................11.2本工程供配电系统概述及相关原则.....................................12负荷的计算..............................................................32.1负荷分级以及要求...................................................32.1.1负荷分级和供电电源要求.......................................32.1.2本工程建筑的负荷类型.........................................42.2计算负荷的分析.....................................................62.2.1概述.........................................................62.2.2计算负荷的步骤...............................................62.2.3本工程负荷计算...............................................93无功补偿...............................................................113.1无功补偿的...
