Cov kws tshawb fawb ntawm Hanbat National University hauv Kaus Lim Qab Teb tau tshawb xyuas qhov kev ua tau zoo ntawm lub tsev sib xyaw photovoltaic (BIPV) qhov muag tsis pom kev cuam tshuam los ntawm qhov ntxoov ntxoo uas tsim los ntawm qhov muag tsis pom slats lawv tus kheej thiab tau pom tias lub kaum sab xis ntawm 90 degrees tuaj yeem txo qhov cuam tshuam no.
"Dab tsi txawv qhov kev tshawb fawb no yog nws qhov tseem ceeb ntawm kev cuam tshuam shading nyob rau hauv cov ntsiab lus ntawm PV blinds, ib qho tseem ceeb feem ntau overlooked," qhov kev tshawb fawb tus sau sau, Jongho Joon. "Txawm hais tias qhov kev qhuas dav dav rau PV qhov muag tsis pom kev muaj peev xwm muaj peev xwm tsim tau ntau lub zog dua li PV modules ruaj khov vim lawv cov kaum sab xis kho tau, txoj kev tshawb fawb tau pom zoo rau kev ua haujlwm zoo txo qis uas tuaj yeem tshwm sim vim qhov cuam tshuam ntawm shading ntawm, saum toj, thiab hauv qab qhov muag tsis pom slats. ."
Cov kws tshawb fawb tau muab piv rau qhov kev ua tau zoo ntawm PV qhov muag tsis pom nrog lub kaum sab xis ua haujlwm nyob rau hauv ntsug thiab inclined tej yam kev mob nyob rau hauv ntsug thiab inclined tej yam kev mob rau kev ua tau zoo ntawm lub kaum sab xis siv BIPV module. Lawv tau siv ob qho chaw sim thiab simulation qauv los sawv cev rau cov xwm txheej tiag tiag.
"Yuav ntsuas cov irradiation xa mus rau qhov teeb tsa module, peb lub pyranometers tau nruab rau ntawm 30 degrees, 90 degrees, thiab 0 degrees rau inclined, ntsug, thiab kab rov tav dav hlau, raws li cov kws tshawb fawb tau teev tseg.
Cov kws tshawb fawb tau tshawb pom tias tshwj tsis yog rau 90-degree lub kaum sab xis, PV qhov muag tsis pom kev pheej hmoo tsim hluav taws xob tsawg dua li cov qauv siv ntawm cov ces kaum sib txawv. Feem ntau, lub kaum sab xis zoo rau PV systems hauv Kaus Lim Kauslim yog 30 degrees.
"Intriguingly, PV blinds tsim lub siab tshaj plaws lub zog ntawm lub kaum sab xis 30 degrees, tab sis qhov sib txawv tseem ceeb ntawm lub zog tawm los piv rau cov qauv siv tau kuj tau sau tseg," Joon piav qhia. "Qhov no qhia tau hais tias qhov siab zog tawm los ua rau muaj kev cuam tshuam rau tus kheej-shading hauv PV blinds."
Cov kws tshawb fawb tau muab piv rau cov khoom siv hluav taws xob ntawm PV qhov muag tsis pom ntawm lawv cov kaum sab xis txhua hli nrog rau cov qauv siv ruaj khov teeb tsa ntawm 30 degrees lossis 90 degrees. PV qhov muag tsis pom kev ua tau zoo tshaj qhov kev siv module kho ntawm 90-degree lub kaum ntse ntse, tab sis lawv lub zog tawm los yog 13 txog 21 feem pua tsawg dua ntawm 30-degree kaum.
"Cov kev tshawb pom no qhia tias kev kho lub kaum sab xis ntawm PV blinds tuaj yeem txhim kho lub zog tsim hluav taws xob, txawm hais tias muaj kev txwv tsis pub muaj los ntawm tus kheej-shading cuam tshuam los ntawm sab sauv slat module," cov kws tshawb fawb tau hais ntxiv.
Pab pawg tshawb fawb kuj tau tshuaj xyuas cov xwm txheej uas cov neeg siv tuaj yeem teeb lub kaum sab xis ntawm PV blinds tsis raug. Lawv muab piv rau lub zog yield ntawm PV blinds teem rau lawv qhov tsawg kawg nkaus pom cov ces kaum txhua lub hli nrog rau cov ntaub ntawv slat module tsau ntawm 30 degrees los yog 90 degrees. Nws pom tau hais tias qhov sib txawv ntawm kev tsim hluav taws xob ua haujlwm. Cov kev siv module ntawm 30 degrees yielded 83-86 feem pua lub zog ntau dua li cov misaligned PV blinds, whereas nws generated 14-28 feem pua tsawg zog yield dua li cov reference module tsau ntawm 90 degrees.
"Qhov no tau hais txog qhov tseem ceeb ntawm kev teeb tsa lub kaum sab xis ntawm PV qhov muag tsis pom los ua kom muaj zog tsim hluav taws xob ntau," cov kws tshaj lij tau hais.
Lawv tau nthuav tawm lub tswv yim tshiab hauv txoj kev tshawb fawb "Power Performance Assessment of PV blinds system xav txog tus kheej-shading teebmeem," luam tawm hauvHnub Ci Zog.
"Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txiaj ntsig tsis xav txog qhov cuam tshuam ntawm kev sib txuas ntawm cov kab sib txuas ntawm cov slat modules thiab bypass diodes," Yoon tau hais txog cov lus qhia yav tom ntej ntawm kev tshawb fawb. "Yog li ntawd, koom nrog cov xwm txheej no nyob rau hauv lub ntiaj teb tiag tiag tej zaum yuav txo tau lub zog tsim hluav taws xob ntawm PV blinds."
