Lub hnub ci vaj huam sib luag, tseem hu ua photovoltaic (PV) vaj huam sib luag, yog ib qho cuab yeej uas hloov lub hnub ci mus rau hluav taws xob tam sim no. Txawm li cas los xij, feem ntau cov khoom siv hluav taws xob, nrog rau cov khoom siv hauv tsev thiab cov motors, feem ntau siv AC alternating tam sim no. Yog li ntawd, txhawm rau kom lub zog tsim los ntawm lub hnub ci vaj huam sib luag siv los ntawm cov cuab yeej no, DC lub zog yuav tsum tau hloov mus rau AC lub zog los ntawm inverter.

Yuav ua li cas txuas solar panels rauinverter

Hnub ci vaj huam sib luag feem ntau yog txuas nrog lub inverter hauv series lossis parallel. Hauv kev sib txuas ua ke, cov hnub ci vaj huam sib luag tau txuas ua ke los tsim cov qib siab voltage, thaum nyob rau hauv ib qho kev sib txuas, cov hnub ci vaj huam sib luag tau txuas ua ke los muab cov theem tam sim no. Inverters tuaj yeem yog nruab nrab, hlua lossis micro-inverters nyob ntawm qhov yuav tsum tau ua thiab tsim qauv.

1. Centralized inverter: Siv nyob rau hauv loj-scale photovoltaic systems, ntau lub hnub ci vaj huam sib luag yog kev cob cog rua nyob rau hauv series thiab parallel mus rau DC input ntawm ib zaug xwb inverter.
2. Txoj hlua inverter: Txhua txoj hlua hnub ci vaj huam sib luag dhau los ntawm lub inverter, uas ua kom zoo dua qhov kev ua haujlwm ntawm cov hlua photovoltaic thiab txhim kho kev ua haujlwm thiab kev ntseeg tau.

3. Microinverter: Txhua lub hnub ci vaj huam sib luag lossis ntau lub vaj huam sib luag txuas nrog lub microinverter cais, uas tuaj yeem ua tiav qhov siab tshaj plaws lub zog taw tes nrhiav (MPPT) rau txhua lub vaj huam sib luag thiab txhim kho tag nrho cov kev ua haujlwm ntawm lub cev.

Yuav ua li cas lub inverter ua haujlwm

Lub luag haujlwm tseem ceeb ntawm lub inverter yog hloov DC lub zog rau hauv AC zog. Cov txheej txheem no suav nrog kev siv hluav taws xob hluav taws xob, xws li transistors thiab diodes, los ua ke hloov pauv cov waveforms tam sim no los ntawm pulse width modulation (PWM) lossis lwm yam kev hloov kho. Lub inverter kuj tseem muaj qhov siab tshaj plaws lub zog taw tes nrhiav (MPPT) algorithm los xyuas kom meej tias cov hnub ci vaj huam sib luag ib txwm ua haujlwm ntawm lawv qhov chaw siab tshaj plaws.

Inverter efficiency thiab kev ua haujlwm

Kev ua haujlwm ntawm inverter yog qhov ntsuas tseem ceeb ntawm nws qhov kev ua tau zoo. High-efficiency inverters tuaj yeem txo qhov poob thaum lub zog hloov pauv thiab ua kom lub zog tag nrho ntawm lub cev. Kev ua tau zoo ntawm lub inverter yog cuam tshuam los ntawm ntau yam, nrog rau nws cov qauv tsim, lub zog hluav taws xob siv, thermal tswj thiab tswj algorithms.

Kev txiav txim siab tsim qauv

Thaum tsim lub hnub ci photovoltaic system, cov hauv qab no yuav tsum tau xav txog:

1. Tag nrho lub zog ntawm lub hnub ci vaj huam sib luag: Qhov no txiav txim siab qhov siab tshaj plaws ntawm cov hluav taws xob uas qhov system tuaj yeem tsim tau.

2. Muaj peev xwm ntawm lub inverter: Lub inverter yuav tsum muaj peev xwm tswj tau lub zog siab tshaj plaws uas tsim los ntawm lub hnub ci vaj huam sib luag.

3. Kev tiv thaiv qhov system: Lub inverter yuav tsum muaj overload, luv Circuit Court thiab overheating tiv thaiv kev ua haujlwm.

4. Compatibility: Lub inverter yuav tsum tau sib xws nrog lub hnub ci vaj huam sib luag thiab kab sib chaws.

5. Kev Txhim Kho thiab Kev Kho: Lub inverter yuav tsum tau muab ntsia raws li cov chaw tsim khoom cov lus qhia thiab khaws cia tsis tu ncua kom ntseeg tau tias kev ua haujlwm zoo ntawm lub cev.

Kev ruaj ntseg thiab kev ua raws cai

Hnub ci PV systems thiab inverters yuav tsum tau tsim thiab teeb tsa ua raws li cov cai hauv zos thiab cov qauv kev nyab xeeb. Inverters feem ntau yuav tsum muaj cov ntawv pov thawj kev nyab xeeb tsim nyog, xws li IEC 62109-1 thiab IEC 62109-2.

Saib xyuas thiab khaws cia

Niaj hnub nimno inverters feem ntau yog nruab nrog kev saib xyuas cov haujlwm uas tuaj yeem saib xyuas kev ua haujlwm ntawm lub sijhawm ntawm lub sijhawm, suav nrog lub zog tsim hluav taws xob, inverter raws li txoj cai thiab lub tswb tsis raug. Qhov no pab cov neeg khiav dej num ua kom zoo dua qhov kev ua tau zoo thiab teb sai sai rau txhua yam teeb meem.

nyob rau hauv xaus

Hnub ci vaj huam sib luag hluav taws xob tsim hluav taws xob siv lub tshuab hluav taws xob siv hluav taws xob hloov hluav taws xob ncaj qha rau hauv kev hloov tam sim no siv rau hauv daim phiaj hluav taws xob lossis ncaj qha rau kev siv hauv tsev. Xaiv txoj cai inverter yog ib qho tseem ceeb kom ntseeg tau tias kev ua haujlwm zoo ntawm qhov system thiab ua kom rov qab los ntawm kev nqis peev zoo tshaj plaws. Cov qauv tsim yuav tsum coj mus rau hauv tus account hom, efficiency, kev nyab xeeb thiab txij nkawm yuav tsum tau ntawm lub inverter, thaum ua raws li cov kev cai thiab cov qauv.
