Kuzivikanwa kwemusika we solar photovoltaic kwakafambisa kusimudzira kwezuvainverterindustry.Kazhinji kutaura, solar inverters yakakamurwa kuita marudzi matatu: centralized inverters, tambo inverters, uye micro inverters.
Centralized inverters, ayo anotanga asangana obva achinja, anonyanya kukodzera zvidyarwa zvemagetsi zvepakati zvine kupenya kwakafanana.Nekuda kwemutengo wayo wakaderera, unonyanya kushandiswa mune yakakura-yakakura yepakati photovoltaic magetsi zviteshi senge mafekitori akakura ane chiedza chezuva chakafanana uye zviteshi zvemagetsi zvemugwenga.
String inverters anoshandiswa kutenderedza obva achinja, kunyanya kune madiki uye epakati matenga ematenga edenga, madiki epasi magetsi zvidyarwa, uye zvimwe zviitiko.Mamiriro ekushandisa akasiyana zvakanyanya, uye anogona kuiswa kumhando dzakasiyana dzezviteshi zvemagetsi, senge epakati magetsi emagetsi, akagoverwa magetsi zviteshi, uye padenga remba, nemutengo wakakwira zvishoma pane zviteshi zvemagetsi zvepakati.
Micro inverters inopindurwa zvakananga uye yakabatana kune grid, inonyanya kukodzera kudzimba uye zvidiki zvakagovaniswa mamiriro.Kazhinji, simba riri pazasi pe1kw, rinonyanya kushanda kune yakagoverwa imba uye diki yakagovaniswa maindasitiri uye ekutengesa padenga remagetsi zviteshi, asi mutengo wakakwira, uye zvakaoma kuchengetedza kana ukatadza.
Utungamiri hwemutengo wakaderera
The inverter industry2010 asati asvika anga asiri eChina.Sezvo inonyanya kukosha photovoltaic musika, Europe yakaverengera inopfuura 60% yepasi rose nyowani photovoltaic yakaiswa gore rega rega pakati pe2004 ne2011. Sesimba guru remagetsi, SMA, hofori yephotovoltaic, yakatanga kugadzira photovoltaic inverters muna 1987, uye yakaunza iyo yekutanga yekutengesa yakatevedzana inverter uye yepakati inverter, inotungamira iyo indasitiri nekuvimba nehunyanzvi zvakanakira.
Musika wepasi rose unongoda kugarwa nemakambani eEurope, uye pakati pepamusoro gumi photovoltaic inverter kutumira, kunze kwemakambani matatu ekuNorth America, mamwe ese anobva kuEurope.Makambani mashanu eEurope, SMA, KACO, Fronius, Ingeteam, uye Siemens chete, anomiririra 70% yemugove wemusika.Chikamu chemusika chemakambani eSMA chasvika 44%, yakaenzana nehafu yemusika we photovoltaic inverter.
Panguva iyo budiriro yephotovoltaic yave kuzara muEurope, China yekuvandudza photovoltaic ichiri muhucheche: kushaikwa kwetsvakiridzo yetekinoroji uye kubudirira kwebudiriro kwave chinhu chikuru chinotadzisa budiriro.Sezvatinoziva tose, photovoltaic inverters inobatanidza photovoltaic array uye girasi remagetsi, iyo inogona kushandura simba reDDC rinogadzirwa nehurongwa kuva AC simba rinodiwa muupenyu kuburikidza nemagetsi emagetsi ekushandura teknolojia, uye inogona kunzi mwoyo weiyo yose photovoltaic system.
Sezvo "brain" ye photovoltaic simba rekugadzira magetsi, kugadzirwa kwayo nekugadzira kunobatanidza simba rekugadzira teknolojia, semiconductor teknolojia, simba remagetsi emagetsi, microcomputer teknolojia, software algorithm programming teknolojia, nezvimwewo. kubatana kupedzisa, inverters yakafanana nevatungamiri vanotumira zvimwe zvikamu nehuropi hwavo, uye kufamba kwavo kwese kuchakanganisa zvakananga maitiro ose e photovoltaic systems.
Kushandura kwayo kushanda uye kuvimbika kwakavewo zviratidzo zvikuru zvekutonga kushanda kweinverter.Chero bedzi simba richiva rakakwirira, rinogona kureva kurasikirwa kwakaderera, iyo ndiyo imwe yenzira dzakakosha mukuderedza mari yemagetsi pa kilowatt awa ye photovoltaic projects.Muna Zvita 2003, Sungrow Power yakaunza China yekutanga 10kW photovoltaic grid yakabatana inverter ine yakazvimirira kodzero yezvivakwa zvehungwaru, zvichiita danho rakakura kumberi mukushandurwa kwakanaka uye nekudaro kutyora hutongi hwekunze.
Optical kuchengetedza kubatanidzwa inzira isingadzivisiki
Iyo yechinyakare grid-yakabatana photovoltaic inverter inogona kungoita imwe-nzira kutendeuka kubva kuDC kuenda kuAC simba, uye inongogadzira magetsi mukati mezuva.Simba rinogadzirwa rinogonawo kukanganiswa nemamiriro ekunze, ayo ane nyaya dzisingatarisirwi.Nekudaro, iyo inverter yekuchengetedza simba inobatanidza mabasa eiyo photovoltaic grid-yakabatana kugadzirwa kwemagetsi uye ekuchengetedza simba zviteshi zvemagetsi, kuchengetedza magetsi emagetsi kana awanda, uye inverting iyo yakachengetwa simba remagetsi kana isina kukwana kuiburitsa kune grid, kuenzanisa simba. kushandiswa kwakasiyana pakati pemasikati neusiku nemwaka yakasiyana, Inobata basa mukuveura ndebvu uye kuzadza mupata.
Iyo magetsi ekuchengetedza inverter uye grid yakabatana inverter ine imwechete tekinoroji.Kunyangwe dunhu rekudzivirira uye buffer redunhu rakasiyana, iyo hardware chikuva uye topology chimiro chakafanana, saka nzira yekudzikisa mutengo inowirirana neiyo photovoltaic.inverter.
Munguva pfupi, kudiwa kwesimba rekuchengetedza uye kuisirwa kunonyanya kufambiswa nedivi repolicy, uye kukanganiswa nezvipingamupinyi pakutora nzvimbo uye kusagadzikana kwemagetsi, hurumende dzakasiyana dzakamhanyisa kuunzwa kwenhevedzano yemitemo yakakodzera kukurudzira musika wekuchengetedza magetsi. .Mamwe mapurovhinzi nemaguta muChina akatoraira kugova nekuchengetwa kwesimba idzva.
Mukufamba kwenguva, kubatanidzwa kwe optical uye kuchengetedza inzira isingadzivisiki, uye mitemo inofanira kutanga kukurudzira kugoverwa uye kuchengetedza simba idzva.Muchirevo, mumamiriro ezvinhu apo simba re photovoltaic rinopiwa zvachose, zvakakosha kugadzirisa 1: 3 kusvika ku1: 5 kuchengetedza simba kuti uwane simba risina kuvharwa.Optical kuchengetedza kubatanidzwa kunotarisirwa kuve ramangwana rakachena simba mhinduro.
