太阳能发电系统分析与简易设计摘要目前，太阳能正经历着由补充能源向替代能源发展的历史阶段。由于电力电子技术的快速发展以及人们对太阳能光伏并网发电重视程度的增加，使得太阳能光伏并网发电发展非常迅速。其中并网逆变器技术的发展在很大程度上提高了太阳能光伏并网发电的效率，降低了其发电成本。本文介绍了光伏发电的背景,研究了光伏发电的基本原理,在此基础上针对项目要求设计出一款符合要求的独立光伏系统,包括控制器基本功能的实现、控制器的保护功能和逆变器的主要电路设计及主程序流程。该设计主要适合中小型光伏系统，具有电路简单、功能较全等优点。关键词：光伏系统，控制器，逆变器TheanalysisandsimpledesignofsolarpowersystemABSTRACTAtpresent,itisthehistoricalstagethatsolarenergyischangingfromadditionalenergytoalternativeenergy.Astherapiddevelopmentofpowerelectronicsandincreasingattentionofsolarphotovoltaticmakingthedevelopmentofsolarphotoaoltaicpowergenerationisveryfast.Thegridinvertertechnologyhasgreatlyimprovedthesolarphotoaoltaicpowergenerationefficiencyandreducingtheircostofelectricity.Thispaperdescribesthebackgroundofthephotovoltaicpowergeneration,andstudiesthebasicprinciplesofphotovoltaicpowergeneration.Onthisbasis,thereisaprojectdesignedtomeettherequirementsofanindependentphotovoltaicsystem,includingtherealizationofthebasicfunctionsofcontroller,controllerofprotectionInverterandthemaincircuitdesignprocessandthemainprogram.Thisdesignissuitforsmallandmedium-sizedphotovoltaicsystem,withtheadvangesofsimplecircuit,andcompletedfunction.KEYWORDS:Photovoltaicsystems,Controller,Inverter目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc325530503"前言PAGEREF_Toc325530503\h1HYPERLINK\l"_Toc325530504"第1章绪论PAGEREF_Toc325530504\h2HYPERLINK\l"_Toc325530505"1.1研究背景PAGEREF_Toc325530505\h2HYPERLINK\l"_Toc325530506"1.2太阳能光伏发电的实用价值和意义PAGEREF_Toc325530506\h3HYPERLINK\l"_Toc325530507"1.2.1清洁能源技术经济性研究现状PAGEREF_Toc325530507\h3HYPERLINK\l"_Toc325530508"1.2.2我国太阳能资源的分布PAGEREF_Toc325530508\h5HYPERLINK\l"_Toc325530509"1.3光伏发电的研究应用现状和前景PAGEREF_Toc325530509\h6HYPERLINK\l"_Toc325530510"1.3.1国外研究应用现状PAGEREF_Toc325530510\h6HYPERLINK\l"_Toc325530511"1.3.2国内研究应用现状PAGEREF_Toc325530511\h8HYPERLINK\l"_Toc325530512"1.3.3太阳能光伏发电的前景PAGEREF_Toc325530512\h9HYPERLINK\l"_Toc325530513"1.4课题的研究内容与目标
