Dab tsi yog photovoltaic, dab tsi yog lub zog cia, dab tsi yog converter, dab tsi yog inverter, dab tsi yog cov ntsiab lus
01, lub zog cia khoom thiab photovoltaic yog ob qho kev lag luam
Qhov kev sib raug zoo ntawm lawv yog tias lub photovoltaic converts hnub ci zog rau hauv lub zog hluav taws xob, thiab lub zog khaws cia lub zog hluav taws xob tsim los ntawm photovoltaic. Thaum twg ntu hluav taws xob hluav taws xob no, nws hloov dua siab tshiab ua lwm yam tam sim no los ntawm lub zog cia hloov dua siab rau kev thauj khoom lossis kev sib tw.
02, piav qhia txog cov ntsiab lus tseem ceeb
Raws li kev sib txuas lus ntxiv: hauv lub neej, qee lub sijhawm yuav tsum hloov AC lub zog, thiab lwm zaus, nws yog ib qho tsim nyog los hloov DC lub zog rau hauv AC Fais Fab. Cov txheej txheem rov qab no sib xws rau Rectification yog txhais raws li inverter Circuit Court. Nyob rau hauv qee qhov kev mob, ib txheej ntawm cov thyristor circuits tuaj yeem siv los ua ob lub rectifier Circuit Court thiab ib inverter Circuit Court. Cov cuab yeej no yog hu ua kev hloov dua siab tshiab, uas suav nrog Rectifiers, Inverters, thiab DC Conventers.
Cia peb nkag siab ntxiv:
Cov lus Askiv ntawm lub converter yog feem ntau pom tau los ntawm cov hluav taws xob hluav taws xob hluav taws xob, thiab nws txoj haujlwm yog kom paub qhov kis tau tus mob ntawm lub hwj chim. Raws li cov sib txawv ntawm cov hluav taws xob ua ntej thiab tom qab hloov dua siab tshiab, nws tau muab faib ua cov hauv qab no:
DC / DC converter, sab pem hauv ntej thiab sab nraub qaum yog DC, lub voltage yog txawv, txoj haujlwm ntawm DC Transformer
AC / DC converter, AC rau DC, lub luag haujlwm ntawm Rectifier
DC / AC converter, DC rau AC, lub luag haujlwm ntawm Inverter
AC / AC converter, sab pem hauv ntej thiab nram qab yog qhov sib txawv, lub luag haujlwm ntawm cov zaus hloov pauv
Ntxiv rau lub Circuit Court tseem ceeb (cuam tshuam Regruit Court, Acverter Circuit Court, AC Conversion Circuit Court thiab DC Converter Circuit Court (lossis tsav Circuit Court) kom tswj hwm lub zog ntawm lub hwj chim hloov lub caij thiab rau Tau paub txoj cai ntawm hluav taws xob hluav taws xob, tswj Circuital.
Lub npe Askiv lub npe Converter yog fais fab hloov dua siab tshiab, uas tswj txoj kev them nyiaj rau pcs, uas tswj txoj kev them nyiaj ntawm lub roj teeb thiab ua yeeb yam AC-DC hloov dua siab tshiab. Nws yog tsim los ntawm DC / AC BIDIRECTIONAL converter thiab cov chaw tswj.
03, pcs kev faib tawm tswv yim
Nws tuaj yeem faib ua ob hom sib txawv, photovoltaic thiab lub zog cia, vim tias cov haujlwm sib piv yog sib txawv:
Hauv kev lag luam photovoltaic, muaj: hom centralized, hlua hom, micro inverter
Inverter-DC rau AC: Lub luag haujlwm tseem ceeb yog hloov dua tshiab tam sim no los ntawm photovoltaic cov cuab yeej siv tam sim no, uas tuaj yeem siv los ntawm cov khoom siv hluav taws xob, uas tuaj yeem siv los ntawm cov khoom siv lossis ua ke rau hauv daim phiaj lossis khaws cia.
Chaw Nruab Nrab: Qhov tau ntawm daim ntawv thov yog loj-teev cov chaw nres tsheb loj, faib cov photovoltaics, thiab cov kev tso zis dav dav ntau dua 250KW
Txoj hlua hom: Cov tau ntawm daim ntawv thov yog loj-teev kev lag luam tsawg dua 250kW, peb-ntu hluav taws xob tsawg dua lossis sib npaug ntawm 10kW, ib-theem) ,
Micro-inverter: Qhov tau ntawm daim ntawv thov tau faib cov photovoltaic (lub zog dav dav yog tsawg dua los yog sib npaug rau 2kw, ib leeg-theem)
Lub zog cia cov tshuab suav nrog: Chaw Cia Khoom Loj, Kev Lag Luam Thiab Lag Luam Cia,Tsev neeg cia, thiab tuaj yeem muab faib ua cov hluav taws xob cia (cov khoom siv hluav taws xob
Hloov-AC-DC hloov dua siab tshiab: kev ua haujlwm tseem ceeb yog los tswj tus nqi thiab tawm ntawm lub roj teeb. Lub DC lub zog tsim tawm los ntawm photovoltaic lub hwj chim ntau dua yog hloov mus rau AC lub zog los ntawm Inverter. Txoj kev hloov tam sim no hloov dua siab tshiab tam sim no rau kev them nyiaj. Thaum lub sijhawm hluav taws xob hluav taws xob no, qhov ncaj qha hauv kev hloov pauv tam sim no (feem ntau 2Hz) los ntawm lub zog hloov pauv rau kev siv los ntawm lub txee lossis txuas nrog daim phiaj. Qhov no yog paug. txheej txheem.
Chaw Nres Tsheb Loj: Lub zog hluav taws xob hauv av, kev ruaj khov cia hluav taws xob, qhov tso zis dav dav yog ntau dua 250kW
Kev Lag Luam Hluav Taws Xob thiab Kev Lag Luam: General Tso Tawm Lub Zog Yog Tsawg Dua lossis sib npaug nrog 250kw
Tsev neeg cia: Cov zis tso zis dav dav yog tsawg dua lossis sib npaug rau 10kW
Kev tso tshuaj hluav taws xob cov khoom siv hluav taws xob: tsuas yog siv AC Coupling cov txheej txheem, thiab daim ntawv thov cov xwm txheej feem ntau yog cia loj
Hybrid inverter: feem ntau yog adopts lub dc coupling txheej txheem, thiab daim ntawv thov cov xwm txheej yog feem ntau cia tsev cia
Txhua-hauv-ib inverter: Lub zog cia khawm + Cov khoom roj teeb, cov khoom yog TESLA thiab ERHase
