Thaum lub installation ntawm ib qho PV system ua tiav thiab kev tshuaj xyuas tiav, lub kaw lus yuav npaj tau los txuas rau daim phiaj xa hluav taws xob. Cov txheej txheem ntawd yog hu ua commissioning lub system.Lub tshuab hluav taws xob photovoltaic (PV) yog tso siab rau lub hnub ci hluav taws xob los tsim lub zog txaus, thiab qhov no yog qhov xav tau ntawm PV system tsim. Yog li ntawd nws yog ib qho tseem ceeb los ntsuas qhov kev ua tau zoo ntawm PV system kom ntseeg tau tias nws tau tsim, ntsia thiab ua tau raws li tus qauv tsim.
Qhov no yog qhov tseem ceeb ntawm PV system commissioning yog, thiab nws ua haujlwm rau ntau lub hom phiaj:
Txhawm rau ntsuas qhov kev ua haujlwm ntawm PV system
Txhawm rau kom ntseeg tau tias kev ua haujlwm ntawm qhov system yuav ua rau lub neej ntev ntawm cov khoom siv thiab cov khoom siv
Rau kev ua raws li kev nyab xeeb thiab lav
Cov cim tseem ceeb ntawm kev ua haujlwm hauv commissioning PV system
Rau cov kab hluav taws xob sib txuas, siv rau British Standard "BS EN 2446 - Grid txuas nrog PV systems - yam tsawg kawg nkaus uas yuav tsum tau muaj rau cov ntaub ntawv kaw lus, commissioning thiab tshuaj xyuas" yog qhov zoo tshaj plaws kom nkag siab txog qhov yuav tsum tau ua hauv thawj qhov kev txheeb xyuas ntawm PV system. thiab tseem ua pov thawj raws sij hawm, cov kev ntsuam xyuas tau teev tseg raws li hauv qab no:
- Insulation Resistance ntsuas
- Qhib Circuit Court voltage ntsuas
- Kev ntsuas luv luv tam sim no
- Txuas ntxiv ntawm kev tiv thaiv conductors ntsuas
Txawm li cas los xij, feem ntau hais lus kuj tseem muaj peb kauj ruam los ua haujlwm rau PV system, txawm hais tias thawj kauj ruam tuaj yeem ua tiav ua ntej lub kaw lus raug teeb tsa thiab tsim kom muaj txiaj ntsig zoo rau lub zog txhua xyoo lossis niaj hnub lub zog yuav tsum muaj peev xwm tsim tau, ie. lub zog muaj peev xwm.
Ntsuas lub zog muaj peev xwm ntawm PV system
Lub peev xwm ntawm cov khoom siv hnub ci yog txiav txim siab los ntawm nws qhov chaw, thiab qhov no yog cuam tshuam los ntawm lub ntuj tsim shading uas yuav cuam tshuam rau lub hnub ci ntawm PV system raug, thiab pes tsawg teev ntawm lub hnub tau txais. Qhov no yog hu ua hnub ci irradiance thiab ntsuas hauv watts ib m2.
Ib tus kws tshaj lij tuaj yeem suav qhov kev xav tau txhua xyoo ntawm lub zog siv lub zog tsim tawm ntawm PV cell thiab muab qhov no los ntawm lub hnub ncov teev (watts ib m2) thiab suav rau hauv cov nyiaj poob hluav taws xob tau ntsib los ntawm kev xaim thiab lub invertor. Qhov no tuaj yeem tsim cov khoom siv hluav taws xob txhua xyoo lossis txhua hnub thiab yog li ua rau kev nyeem ntawv hauv qab ntawm qhov system 'yuav tsum' tsim thaum nws tau teeb tsa. Tus kws tshaj lij tuaj yeem tsim tau seb lub kaw lus, raws li tam sim no teeb tsa 'ntawm daim ntawv', yuav ua tau raws li tus qauv tsim thiab yog li tuaj yeem ua qhov tsim nyog hloov kho ua ntej kev teeb tsa.
Kev ntsuas PV kev ua haujlwm
Qhov no yog ua tiav thaum PV system tau teeb tsa thiab ua los txiav txim siab seb lub kaw lus puas ua haujlwm raws li tsim. Ua li no peb yuav saib kev ntsuas kev sib raug zoo ntawm qhov tam sim no thiab voltage (IV) nyob rau hauv ib qho system los ntawm kev tsim lub hnub ci IV nkhaus. Lub hnub ci IV nkhaus yog cov duab sawv cev ntawm qhov PV system ua haujlwm li cas hauv nws cov xwm txheej uas twb muaj lawm. Daim duab qhia cov ntaub ntawv xav tau rau cov kws tsim khoom los teeb tsa PV system kom nws ua haujlwm rau nws qhov zoo tshaj plaws, piv txwv li. tus tsim spec thiab lub zog ua tau zoo tsim nyob rau hauv ib kauj ruam saum toj no. Yog li ntxiv, puas yog PV system ua tau raws li tus qauv tsim?
Troubleshooting - kuaj xyuas cov teeb meem thiab daws lawv
Yog li yog tias PV system tso tawm tsis tau raws li qhov xav tau, koj yuav tsum txheeb xyuas tias vim li cas qhov no yog thiab qhov kev hloov pauv tuaj yeem ua tau. Cov teeb meem tshwm sim tuaj yeem yog qhov qhib hluav taws xob hluav taws xob lossis hluav taws xob luv luv hluav taws xob siab dua lossis qis dua li qhov yuav tsum tau ua, lossis yog tias cov zis hluav taws xob tsawg. Qhov twg muaj qhov tsis sib xws hauv kev ua tau zoo piv rau qhov kev xav tau ntawm tus qauv tsim, tus kws tshaj lij tuaj yeem ua qhov kev sim los txheeb xyuas lossis hloov cov qauv hauv qhov system raws li, siv ntau yam khoom siv hnub ci PV ntsuas.
ua PV system commissioning
PV system commissioning yog cov txheej txheem tseem ceeb ntawm txhua qhov kev teeb tsa PV, thiab yuav tsum tau qhia los ntawm cov tswv tsev, cov thawj tswj hwm lossis cov neeg ua haujlwm engineering, tab sis yuav ua los ntawm cov kws tsim hluav taws xob tsim nyog lossis cov kws tsim khoom tsim khoom.
Qhov tseem ceeb ntawm PV system commissioning
Qhov tseem ceeb, commissioning PV system xyuas kom meej tias nws ua tau raws li tus qauv tsim. Ib qho PV system tuaj yeem yog ib qho kev nqis peev tseem ceeb thiab kev ncaj ncees rau qhov no feem ntau ntsuas raws li kev them nyiaj rov qab, piv txwv li. pes tsawg xyoo ntawm kev txuag hluav taws xob yuav tau ntsib ua ntej thawj zaug peev nyiaj rov qab. Yog li nws yog ib qho tseem ceeb heev uas lub kaw lus ua haujlwm rau spec tam sim ntawd thiab them rov qab tuaj yeem ntsuas, thiab qhov no yog lub hom phiaj tseem ceeb ntawm PV system commissioning. Qhov no thaum kawg yuav txuag lub sijhawm thiab nyiaj txiag ntawm kev teeb tsa thiab kev ua haujlwm, ua kom cov qauv tsim tsim nyog rau kev ua haujlwm thiab ib puag ncig koj muaj thiab ua kom muaj kev ntseeg siab hauv qhov system.
Yog li commissioning PV system yog qhov tseem ceeb rau ntau yam sib txawv:
- Paub meej tias PV system yuav ua tau raws li nws cov hom phiaj kev ua tau zoo
- Qhia seb qhov system ua haujlwm li cas
- Paub txog tag nrho cov peev txheej thiab lub peev xwm ntawm lub kaw lus yog tias muaj teeb meem pib
- Xyuas kom cov neeg tsim qauv tsim muaj lub luag haujlwm
- Nws xa cov kev xav txuag hluav taws xob tam sim ntawd.
Thov nco ntsoov tias ntu no yog siv rau cov ntaub ntawv xov xwm nkaus xwb. Txhua tus neeg siv cov cuab yeej xa mus rau hauv ntu no yuav tsum tsim nyog thiab / lossis muaj kev paub dhau los hauv thaj chaw. Yog tias tsis ntseeg ua ntej siv, thov sab laj nrog tus kws tshaj lij hluav taws xob lossis tus kws tshaj lij thiab nyeem tag nrho cov phau ntawv qhia.
