Nyob rau hauv xyoo tas los no, lub hnub ci zog tau dhau los ua ib qho kev cog lus zoo tshaj plaws ntawm lub zog tauj dua tshiab.Raws li kev siv thev naus laus zis, cov hnub ci vaj huam sib luag tau ua haujlwm tau zoo thiab pheej yig dua, ua rau lawv nkag tau yooj yim rau cov tswv tsev thiab cov lag luam.Ib qho ntawm cov khoom tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm lub hnub ci vaj huam sib luag yog lub hnub ci PV.vaj huam sib luag optimizer.
Lub hnub ci photovoltaicvaj huam sib luag optimizeryog ib qho cuab yeej muab tso rau nruab nrab ntawm txhua lub hnub ci vaj huam sib luag hauv cov array.Nws lub luag haujlwm tseem ceeb yog ua kom lub zog tawm ntawm txhua lub vaj huam sib luag los ntawm kev ua kom ntseeg tau tias txhua lub vaj huam sib luag ua haujlwm ntawm nws lub zog siab tshaj plaws.Qhov no yog ib qho tseem ceeb vim hais tias nyob rau hauv ib tug raug lub hnub ci vaj huam sib luag installation, lub panels txuas nrog nyob rau hauv series, uas txhais tau hais tias kev ua tau zoo ntawm tag nrho cov system yuav cuam tshuam los ntawm qhov tsawg tshaj plaws ua vaj huam sib luag.Los ntawm optimizing lub zog tso zis ntawm txhua lub vaj huam sib luag, tag nrho cov system efficiency thiab lub zog ntau lawm yog ho txhim kho.
Hnub ci PVvaj huam sib luag optimizersua haujlwm los ntawm kev tuaj yeem saib xyuas thiab tswj qhov voltage thiab tam sim no ntawm txhua lub vaj huam sib luag ntawm tus kheej.Lub optimizer txuas ntxiv txheeb xyuas cov yam ntxwv hluav taws xob ntawm txhua lub vaj huam sib luag thiab kho nws qhov chaw ua haujlwm raws li.Qhov no ua tiav los ntawm kev siv tshuab hu ua Maximum Power Point Tracking (MPPT).
MPPT yog raws li lub tswv yim hais tias lub hnub ci vaj huam sib luag muaj qhov tshwj xeeb qhov hluav taws xob uas lawv lub zog tso zis ntau tshaj plaws.Raws li cov hnub ci thiab qhov kub thiab txias hloov pauv txhua hnub, lub vaj huam sib luag kev khiav hauj lwm voltage kuj hloov.Lub luag haujlwm ntawm optimizer yog taug qab cov kev hloov pauv no thiab xyuas kom meej tias txhua lub vaj huam sib luag ua haujlwm ntawm nws qhov kev pom zoo voltage thiab qib tam sim no kom ua kom lub zog tso zis ntau tshaj.
Ntxiv rau qhov ua kom muaj zog ntau lawm, hnub ci PVvaj huam sib luag optimizersmuab ob peb lwm yam zoo.Ib qho txiaj ntsig tseem ceeb yog txhim kho kev ntseeg tau.Nyob rau hauv ib txwm tandem hnub ci vaj huam sib luag teeb, yog tias ib lub vaj huam sib luag yog ntxoov ntxoo los yog ua tsis tiav, kev ua tau zoo ntawm tag nrho cov system raug kev txom nyem.Nrog rau qhov optimizer, qhov cuam tshuam ntawm cov teeb meem zoo li no tau txo qis vim tias txhua lub vaj huam sib luag tuaj yeem ua haujlwm ntawm nws tus kheej ntawm nws qhov kev pom zoo, txawm tias cov vaj huam sib luag nyob ib sab raug cuam tshuam.
Tsis tas li ntawd, lub hnub ci PVVaj huam sib luag Optimizerua kom zoo dua kev saib xyuas thiab kuaj mob.Ntau cov optimizers tau nruab nrog cov kev soj ntsuam siab heev uas muab cov ntaub ntawv hauv lub sijhawm ntawm kev ua haujlwm ntawm tus kheej.Qhov no ua rau cov neeg siv tuaj yeem txheeb xyuas cov teeb meem uas muaj peev xwm lossis qhov tsis raug, ua rau kev saib xyuas thiab daws teeb meem zoo dua.
Tsis tas li ntawd, nyob rau hauv cov xwm txheej uas cov hnub ci vaj huam sib luag tau teeb tsa hauv ntau qhov kev taw qhia lossis qhov chaw, qhov kev ua kom zoo tuaj yeem pab txo qis kev ua haujlwm tsis zoo hauv vaj huam sib luag.Los ntawm kev ua kom zoo rau txhua lub vaj huam sib luag ntawm tus kheej, txawm tias lawv ntsib qhov sib txawv shading lossis orientation tej yam kev mob, tag nrho cov kev ua tau zoo tuaj yeem txhim kho.Qhov no ua rau lub optimizer tshwj xeeb tshaj yog muaj txiaj ntsig zoo nyob rau hauv cov xwm txheej uas qhov chaw lossis ib puag ncig txwv txwv qhov kev tso kawm zoo tshaj plaws ntawm cov vaj huam sib luag.
Raws li qhov kev thov rau lub hnub ci zog txuas ntxiv mus ntxiv, yog li qhov tseem ceeb ntawm kev ua kom zoo dua ntawm kev teeb tsa lub hnub ci vaj huam sib luag.Hnub ci PVvaj huam sib luag optimizersmuab cov kev daws teeb meem txhim khu kev qha thiab tus nqi tsim nyog los ua kom muaj zog ntau lawm, txhim kho kev ntseeg tau thiab ua kom muaj kev saib xyuas zoo dua.Muaj peev xwm ua kom lub zog tso zis ntau tshaj plaws ntawm txhua lub vaj huam sib luag, cov cuab yeej no ua lub luag haujlwm tseem ceeb hauv kev ua lub hnub ci zog rau kev xaiv rau yav tom ntej.
