Thawj yam ua ntej:
photovoltaic yog dab tsi, dab tsi yog lub zog cia, dab tsi yog converter, dab tsi yog inverter, dab tsi yog PCS thiab lwm yam ntsiab lus
01 Lub zog cia thiab photovoltaic yog ob qho kev lag luam
Kev sib raug zoo ntawm lawv yog tias lub tshuab hluav taws xob photovoltaic hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob, thiab lub zog cia khoom khaws cov hluav taws xob hluav taws xob tsim los ntawm cov khoom siv photovoltaic.Thaum qhov no ntawm hluav taws xob lub zog xav tau, nws hloov mus rau hauv alternating tam sim no los ntawm lub zog cia converter rau load los yog daim phiaj siv.
02 Kev piav qhia ntawm cov ntsiab lus tseem ceeb
Raws li Baidu cov lus piav qhia: hauv lub neej, qee lub sijhawm yuav tsum tau hloov AC lub zog rau hauv DC lub zog, uas yog qhov kev hloov kho, thiab lwm lub sijhawm, nws yuav tsum tau hloov DC lub zog rau hauv AC lub zog.Cov txheej txheem thim rov qab no sib raug rau kev kho kom raug txhais tau tias yog inverter Circuit Court.Nyob rau hauv tej yam kev mob, ib txheej ntawm thyristor circuits yuav siv tau raws li ib tug rectifier Circuit Court thiab ib tug inverter Circuit Court.Cov cuab yeej no hu ua lub converter, uas muaj xws li rectifiers, inverters, AC converters, thiab DC converters.
Cia peb nkag siab dua:
Cov lus Askiv ntawm lub converter yog converter, uas feem ntau pom tau los ntawm cov khoom siv hluav taws xob hluav taws xob, thiab nws txoj haujlwm yog kom paub txog kev xa hluav taws xob.Raws li qhov sib txawv ntawm qhov voltage ua ntej thiab tom qab hloov dua siab tshiab, nws muab faib ua hom hauv qab no:
DC / DC converter, pem hauv ntej thiab nram qab yog DC, qhov voltage sib txawv, muaj nuj nqi ntawm DC transformer
AC / DC converter, AC rau DC, lub luag hauj lwm ntawm lub rectifier
DC / AC converter, DC rau AC, lub luag hauj lwm ntawm lub inverter
AC / AC converter, pem hauv ntej thiab rearfrequencies txawv, lub luag hauj lwm ntawm lub zaus converter
Ntxiv rau lub ntsiab Circuit Court (raws li rectifier Circuit Court, inverter Circuit Court, AC hloov dua siab tshiab Circuit Court thiab DC converter Circuit Court), lub converter kuj yuav tsum muaj ib tug trigger Circuit Court (los yog tsav Circuit Court) tswj lub on-off ntawm lub hwj chim switching caij thiab mus paub txog cov kev cai ntawm hluav taws xob hluav taws xob, tswj Circuit Court.
Lub npe lus Askiv ntawm lub zog cia converter yog Lub Hwj Chim Hloov Pauv, hu ua PCS, uas tswj cov txheej txheem them thiab tawm ntawm lub roj teeb thiab ua AC-DC hloov dua siab tshiab.Nws yog tsim los ntawm DC / AC bidirectional converter thiab ib chav tswj.
03PCS kev faib tawm dav dav
Nws tuaj yeem muab faib los ntawm ob qhov kev lag luam sib txawv, photovoltaic thiab lub zog cia, vim tias cov haujlwm sib xws yog qhov sib txawv:
Hauv kev lag luam photovoltaic, muaj: hom centralized, hom hlua, micro inverter
Inverter-DC rau AC: Lub luag haujlwm tseem ceeb yog hloov cov tam sim no ncaj qha los ntawm lub hnub ci zog rau hauv kev hloov tam sim no los ntawm cov khoom siv hluav taws xob photovoltaic, uas tuaj yeem siv los ntawm kev thauj khoom lossis kev koom ua ke rau hauv daim phiaj lossis khaws cia.
Centralized: Scope ntawm daim ntawv thov yog loj-scale hauv av fais fab chaw nres tsheb, faib kev lag luam thiab kev lag luam photovoltaics, thiab cov tso zis ntau zog yog ntau tshaj 250KW
Txoj hlua hom: cov peev txheej ntawm daim ntawv thov yog cov chaw tsim hluav taws xob loj hauv av, faib kev lag luam thiab kev lag luam photovoltaics (tswj cov zis hluav taws xob tsawg dua 250KW, peb theem), cov khoom siv hluav taws xob hauv tsev (cov khoom siv hluav taws xob ntau dua lossis sib npaug rau 10KW, ib theem) ,
Micro-inverter: lub peev xwm ntawm daim ntawv thov yog faib photovoltaic (cov khoom siv hluav taws xob dav dav tsawg dua lossis sib npaug ntawm 5KW, peb theem), cov khoom siv hluav taws xob hauv tsev (feem ntau cov zis hluav taws xob tsawg dua lossis sib npaug rau 2KW, ib theem)
Lub zog cia cov tshuab muaj xws li: kev cia loj, kev lag luam thiab kev lag luam cia, tsev cia khoom, thiab tuaj yeem muab faib ua lub zog cia hloov pauv (tseem siv hluav taws xob cia hloov pauv, Hybrid) thiab cov tshuab ua ke.
Hloov-AC-DC hloov dua siab tshiab: Lub luag haujlwm tseem ceeb yog tswj cov nqi thiab tawm ntawm lub roj teeb.Lub zog DC tsim los ntawm kev tsim hluav taws xob photovoltaic hloov mus rau AC lub zog los ntawm inverter.Lub alternating tam sim no yog hloov mus rau tam sim no ncaj qha rau them.Thaum qhov no ntawm lub zog hluav taws xob xav tau, qhov ncaj qha tam sim no hauv lub roj teeb yuav tsum tau hloov pauv mus rau qhov hloov pauv tam sim no (feem ntau 220V, 50HZ) los ntawm lub zog cia hloov pauv rau kev siv los ntawm kev thauj khoom lossis txuas nrog daim phiaj.Qhov no yog tso tawm.txheej txheem.
Loj cia: chaw nres tsheb hauv av, ywj siab lub zog cia chaw nres tsheb, lub zog tso zis ntau dua 250KW
Kev lag luam thiab kev lag luam cia: cov khoom siv hluav taws xob dav dav tsawg dua lossis sib npaug li 250KW Cov Khoom Siv Hauv Tsev: Cov zis hluav taws xob dav dav tsawg dua lossis sib npaug li 10KW
Ib txwm siv zog cia converters: feem ntau yog siv AC coupling tswvyim, thiab daim ntawv thov scenarios yog loj cia
Hybrid: feem ntau yog siv DC coupling scheme, thiab daim ntawv thov scenario feem ntau yog hauv tsev cia khoom
All-in-ib tshuab: lub zog cia converter + roj teeb pob, cov khoom lag luam yog Tesla thiab Ephase
