基于长治50MW光伏电站设计研究摘要随着全球环境恶化和能源短缺的现象不断加深，可再生能源的探索工作逐渐加大。太阳能作为一种重要可再生能源，正渐渐的广泛用于清洁发电项目。近几年我国加大对光伏电站建设的政策扶持，促进许多投资方大力加入光伏发电项目中，促使光伏电站设计成为新型电气设计课题，越来越多的技术研究正在进行中，争论最大点在光伏组件和继电保护方案。我于2013年参与长治地区50MW光伏电站设计重点对光伏组件进行设计和继电保护设计研究。本文主要工作：（1）对光伏电站的国内外研究现状进行了概述，并对其进行了归纳和分析。（2）对长治地区太阳能能源进行分析，判断是否适合光伏电站建设。（3）对光伏电站选址进行分析，打破传统占用沙漠和荒地常规，研究利用市中心周边农村日光温室大棚的屋顶建设太阳能光伏发电系统，集太阳能发电、温室大棚特色种植为一体。（4）对光伏电站的核心光伏电池、光伏支架、逆变器、光伏电池子方阵进行计算设计，制定光伏方阵设计方案。（5）对光伏系统整体进行设计，特别对继电保护进行重点设计，通过通信设计电网随时判断光伏电站运行情况并在故障下动作切除，确保电网安全运行。（6）本文对所做工作进行了总结，并对将来光伏电站设计发展进行了展望。关键词：太阳能资源评估方法,光伏组件选型,光伏电站继电保护设计，通信设计IAbstractWiththedeteriorationoftheglobalenvironmentandenergyshortagecontinuingdeepen,renewableenergyexplorationworkincreasesgradually.Asanimportantrenewableenergy,Solarenergyiswidelyusedforcleanpowergenerationprojectsgradually.Inrecentyears,ourcountryincreasesthepolicalsupportfortheconstructionofphotovoltaicpowerstation,andpromotesmanyinvestorstojointhephotovoltaicpowerstationproject,andpushesthedesignofphotovoltaicpowerstationtobacameanewelectricaldesignsubject.moreandmoreresearchtechnologyisunderway,.andthemaximumpointisthedebateinPVmoduleandrelayprotectionscheme.Ihavebeenparticipatedinthe50MWphotovoltaicpowerstationdesigninChangzhiareain2013,andthemaximumpointisthedebateinPVmoduleandrelayprotectionscheme.Themainworkisasfollows:(1)Overviewtheresearchstatusofphotovoltaicpowerplantsindomesticandoverseasandmakeconclusionandanalysis.(2)AnalyzethesolarenergyinChangzhiareaanddeterminethesuitablefortheconstructionofphotovoltaicpowerstation..(3)Analyzethephotovoltaicpowerstationsite.Breakthetraditionaloccupationofdesertsandwastelandsofconventional,roofconstructionofsolarphotovoltaicpowergenerationsystemusingdowntownsurroundingruralsolargreenhouse,asetofsolarpowergeneration,greenhouseplantingfeaturesasawhole.(4)Designcalculationofthephotovoltaicpowercoreofphotovoltaiccells,photovoltaicbracket,inverter,photovoltaicsquaresub,andtheformulationofphotovoltaicarray.(5)Designofthephotovoltaicsystemasawhole,especiallythedesignoftherelayprotection.throughthecommunicationnetworkpowergridjudgethePVpowerplantandactionresectionunderfaultcondition,istoensurethesafeoperationofpowergrid.(6)Finally,summarizealltheworkofthispaperandoutlookthenextwork.Keywords:solarenergyresourceassessmentmethod,selectionofphotovoltaicmodules,designofphotovoltaicpowerstation,designofrelayprotectionforphotovoltaicpowerstation,designofcommunicationII目录摘要................................................................................................................................IABSTRACT....................................................................................................................II1绪论..................................................................................................................................
