某阀门生产企业变配电系统设计摘要电能是当代机械和工业生产的关键的驱动力。电磁能不仅很容易从其他种类的电能转化或再生，而且非常容易用作其他种类的电能。电能生产和使用的各种方法；电磁能的传输，运输和分配既简单又经济。在大多数技术专业加工厂中，制造商必须立即联系电源和配电系统的系统集成中使用的电路原理和技术。涉及多个领域，有效计算负载和补偿无输出功率，有效分配短路故障类型，变压器短路故障的数量和数量，有效准确地测量电源短路，选择类型机械和设备，以及有效的路线分配，有必要进行与电路原理和许多其他重要方面密切相关的电路原理和技术指标的分析，并整合最佳的工业生产电源和配电系统电路原理和技术应用到实际工业生产中，以促进我国的社会经济和社会经济有序发展，为基础设施建设做出贡献。本次设计中包括用电设备的用电负荷计算，进而对本工厂的变电所进行设计，通过短路计算选择高低压电气设备。以及10kv电力系统的质量及损耗，通过并联电工容器进行无功补偿尽量减少系统中的电力能源的损失。用以提高电源及电压的质量，从而提高整体电力系统的安全可靠性。关键词：变电所，负荷计算，无功补偿计算，高低压供配电系统；IIIAbstractElectricityisthekeydrivingforceofcontemporarymachineryandindustrialproduction.Electromagneticenergyisnotonlyeasytoconvertorregeneratefromotherkindsofelectricenergy,butalsoveryeasytouseasotherkindsofelectricenergy.Variousmethodsofelectricenergyproductionanduse;electromagneticenergytransmission,transportationanddistributionaresimpleandeconomical.Inmosttechnicalprofessionalprocessingplants,manufacturersmustimmediatelycontactthecircuitprinciplesandtechnologiesusedinthesystemintegrationofpowerandpowerdistributionsystems.Involvedinmultiplefields,effectivecalculationofloadandcompensationofnooutputpower,effectivedistributionofshort-circuitfaulttypes,thenumberandquantityoftransformershort-circuitfaults,effectiveandaccuratemeasurementofpowershort-circuits,selectionoftypesofmachineryandequipment,andeffectiverouteallocationarenecessaryAnalysisofcircuitprinciplesandtechnicalindicatorscloselyrelatedtocircuitprinciplesandmanyotherimportantaspects,andintegratethebestindustrialproductionpowersupplyandpowerdistributionsystemcircuitprinciplesandtechnologiesintoactualindustrialproductiontopromoteChina’ssocialeconomyandsocietyTheeconomydevelopsinanorderlymanner,contributestoinfrastructureconstruction,andmakesthebesttechnicalcontribution.Thisdesignincludesthecalculationoftheelectricalloadoftheelectricalequipment,andthenthedesignofthesubstationofthefactory,throughtheshort-circuitcalculationtochoosethehighandlowvoltageelectricalequipment.Andthequalityandlossofthe10kVpowersystem.Reactivepowercompensationiscarriedoutthroughtheparallelelectricalcontainertominimizethelossofpowerenergyinthesystem.Toimprovethequalityofpowersupplyandvoltage,soastoimprovethesafetyandreliabilityofthewholepowersystem.Keywords:powersupplysystem;Powerload;Shortcircuitcurrent;III目录第一章绪论.........................................................11.1选题背景....................................................11.2研究意义....................................................21.3设计原始资料................................................21.3.1供电系统的确定.................................................2第二章负荷计算及无功补偿...........................................42.1负荷概述....................................................42.2负荷计算....................................................42.1.1负荷计算公式.........................................
