Taw qhia
Hnub ci inverter, tseem hu ua hluav taws xob tswj hluav taws xob, yog cov cuab yeej tseem ceeb hauv cov txheej txheem ntawm daim phiaj - txuas hnub ci photovoltaic fais fab tuag.Solar inverter yog cov cuab yeej tseem ceeb hauv lub hnub ci photovoltaic system, nws lub luag haujlwm tseem ceeb yog hloov cov hluav taws xob ncaj qha (DC) tsim los ntawm hnub ci vaj huam sib luag rau hauv alternating tam sim no (AC), kom nws tuaj yeem muab tso rau hauv cov khoom siv ncaj qha rau hauv g.
Txoj Cai Ua Haujlwm
Lub hnub ci inverter converts ncaj qha tam sim no mus rau hauv alternating tam sim no los ntawm nws sab hauv circuits, xws li MPPT (qhov siab tshaj plaws lub zog taw tes nrhiav) system, DC -DC converters, inverter circuits, lim, thiab lwm yam. Lub inverter kuj yog lub luag hauj lwm rau tiag tiag - lub sij hawm saib xyuas thiab kev tswj kom ntseeg tau tias lub photovoltaic system ua hauj lwm ntawm qhov siab tshaj plaws efficiency thiab los tiv thaiv qhov system tam sim no.
Hom Thiab Yam ntxwv
1.Centralized inverter:
Daim ntawv thov scenario:Feem ntau yog siv nyob rau hauv centralized loj -scale av photovoltaic fais fab chaw nres tsheb nrog cov teeb pom kev zoo, xws li roob, suab puam, dej thiab lwm yam scenes.
Nta:lub zog loj, me me, yooj yim los tswj; Cov khoom tsawg dua, kev ruaj ntseg zoo, yooj yim los tswj; Muaj lub zog hloov pauv muaj nuj nqi thiab tsis tshua muaj hluav taws xob hla kev ua haujlwm, kev tswj hwm kab sib chaws zoo. Tab sis MPPT voltage ntau yog nqaim, cov khoom siv tsis hloov pauv; Kev siv hluav taws xob thiab qhov cua thiab cua kub dissipation ntawm chav tsev khoom yog loj.
2.Series inverter:
Daim ntawv thov scenario:Muaj feem xyuam rau cov chaw nres tsheb hauv nruab nrab, cov chaw nres tsheb fais fab, thiab cov chaw me me thiab nruab nrab -cov chaw nres tsheb loj loj.
Nta:Lub hwj chim me me, tab sis MPPT qhov hluav taws xob ntau yog qhov dav, cov khoom siv sib txuas yog hloov tau; Nws tsis cuam tshuam los ntawm qhov sib txawv module thiab duab ntxoov ntxoo occlusion, thiab lub zog tsim tau nce mus rau qhov siab tshaj plaws. Kev siv hluav taws xob tsawg thiab cuam tshuam tsis zoo. Txawm li cas los xij, qhov sib txawv ntawm cov khoom siv hluav taws xob yog me me, uas tsis haum rau qhov chaw siab tshaj; Cov khoom siv ntau dua, kev sib xyaw ua ke, kev ruaj ntseg me ntsis; Kev teeb tsa sab nraum zoov yooj yim ua rau kev laus ntawm lub plhaub thiab lub dab dej kub; Tus naj npawb ntawm inverters yog loj, tag nrho cov tsis ua hauj lwm tus nqi yuav nce, thiab cov kev soj ntsuam system yog nyuaj. Tsis muaj kev sib cais transformer tsim, hluav taws xob kev nyab xeeb yog me ntsis tsis zoo.
3.Distributed inverter:
Daim ntawv thov scenario:Nws kuj yog tsim rau centralized loj -scale av photovoltaic fais fab nroj tsuag, xws li roob, suab puam, dej thiab lwm yam scenes.
Nta:Ua ke qhov zoo ntawm centralized inverter thiab series inverter, nws muaj cov yam ntxwv ntawm "centralized inverter" thiab "decentralized MPPT taug qab". Qhov no txo cov nqi tsim kho thiab ua kom muaj hluav taws xob ntau ntxiv. Txawm li cas los xij, raws li daim ntawv tshiab, cov khoom siv hluav taws xob faib tawm yog tsawg tsawg hauv kev siv cov haujlwm engineering, thiab nws txoj kev nyab xeeb, kev ruaj ntseg thiab cov khoom siv hluav taws xob siab tseem yuav tsum tau mus los ntawm kev tshuaj xyuas cov haujlwm engineering.
4. Micro inverter:
Daim ntawv thov scenario:Feem ntau tsim nyog rau kev faib khoom siv hauv tsev thiab me me faib kev lag luam thiab kev lag luam hauv tsev hluav taws xob hauv tsev.
Nta:Lub zog siab tshaj plaws ntawm txhua qhov photovoltaic module yog taug qab sib cais, thiab tom qab ntawd muab tso rau hauv AC zog daim phiaj los ntawm inverter. Lub micro inverter muaj qhov ntim tsawg tshaj plaws thiab lub zog tsawg tshaj plaws, thiab lub zog dav dav yog qis dua 1 kilowatt.
Qhov zoo
1. Tsis siv neeg ua haujlwm thiab kaw:Lub photovoltaic inverter tuaj yeem pib lossis nres ua haujlwm raws li lub xeev ntawm daim phiaj lossis teeb pom kev zoo kom ntseeg tau tias kev ruaj ntseg thiab kev nyab xeeb ntawm lub cev.
2.Integration thiab modularization:Kev sib koom ua ke thiab kev hloov pauv ntawm inverters tuaj yeem ua kom yooj yim rau kev tsim thiab kev teeb tsa ntawm cov tshuab photovoltaic thiab txhim kho kev ntseeg tau thiab ruaj khov ntawm lub system.
3.Green ib puag ncig tiv thaiv thiab kev txhim kho kom ruaj khov:Raws li ib feem tseem ceeb ntawm cov txheej txheem photovoltaic, lub inverter qhov kev ua tau zoo ib puag ncig thiab kev txhim kho kom ruaj khov kuj tau dhau los ua qhov tseem ceeb ntawm kev mloog. Cov tuam txhab lag luam yuav tsum tau ua tib zoo saib xyuas cov kev cai ib puag ncig thiab cov kev xav tau ntawm kev ruaj ntseg, thiab txais yuav cov ntaub ntawv zoo ib puag ncig thiab lub zog-txuag thev naus laus zis los txo qhov cuam tshuam ib puag ncig ntawm lawv cov khoom.
Kev loj hlob
Hnub ci inverters tab tom tsim nyob rau hauv kev coj ntawm lub zog cia thiab kev txawj ntse. Nrog rau qhov nce ntawm kev teeb tsa photovoltaic thiab kev loj hlob ntawm kev thov rau lub zog cia tshuab, cov tuam txhab photovoltaic inverter tau nkag mus tob rau hauv thaj chaw ntawm lub zog cia thiab txhim kho lub zog cia roj teeb thiab cov khoom siv. Nyob rau tib lub sijhawm, lub ntse inverter tuaj yeem paub txog cov ntaub ntawv tau txais, kev tswj hwm lub zog thiab kev saib xyuas chaw nres tsheb fais fab, thiab txhim kho kev ua haujlwm ntawm lub chaw nres tsheb fais fab.
