Lub zog tsim hluav taws xob yog lub hauv paus ntawm photovoltaic fais fab nroj tsuag. Cov chaw nres tsheb fais fab nrog tib lub peev xwm yuav muaj ntau yam sib txawv zog. Qhov txawv ntawm lub zog tsim hluav taws xob ntawm lub chaw nres tsheb fais fab tuaj li cas? Yam dab tsi yuav muaj kev cuam tshuam loj rau kev tsim hluav taws xob ntawm qhov system?
PV modules yog tib qhov chaw tsim hluav taws xob
Lub module hloov lub zog hluav taws xob los ntawm lub hnub ci mus rau qhov ntsuas hluav taws xob ncaj qha tam sim no los ntawm cov nyhuv Photovoltaic. Yog tsis muaj cov khoom siv lossis lub peev xwm ntawm cov khoom siv tsis txaus, txawm hais tias lub inverter zoo npaum li cas, tsis muaj dab tsi ua tau, vim tias lub inverter tsis tuaj yeem hloov cua mus rau hauv hluav taws xob. Yog li ntawd, xaiv cov khoom tsim nyog thiab cov khoom lag luam zoo yog qhov khoom plig zoo tshaj plaws rau qhov chaw nres tsheb fais fab; nws kuj yog ib qho kev lav zoo rau cov nyiaj tau los ruaj khov mus ntev.
Txoj hlua tsim yog qhov tseem ceeb. Tib tus naj npawb ntawm cov khoom siv yog siv nyob rau hauv txoj hlua sib txawv, thiab kev ua haujlwm ntawm qhov chaw nres tsheb fais fab yuav txawv. Qhov ntsuas ua haujlwm voltage ntawm peb-theem inverter feem ntau yog nyob ib ncig ntawm 600V. Yog tias txoj hlua hluav taws xob tsawg, lub zog hluav taws xob ua haujlwm nquag, uas yuav muaj qee yam cuam tshuam rau kev ua haujlwm. Noj 56 daim ntawm 445Wp monocrystalline silicon modules nrog 20KW inverter ua piv txwv, lub zog tsim ntawm txoj hlua txoj hlua yog siab dua li ntawm txoj hlua txoj hlua.
Kev teeb tsa thiab kev teeb tsa ntawm cov khoom yog qhov tseem ceeb
Nrog rau tib lub peev xwm module nyob rau hauv tib qhov chaw installation, kev taw qhia, kev npaj, inclination ntawm lub module, thiab seb nws yog thaiv yuav muaj ib qho tseem ceeb cuam tshuam rau lub hwj chim. Cov qauv dav dav yog nruab rau sab qab teb. Hauv kev tsim kho tiag tiag, txawm tias lub xeev qub ntawm lub ru tsev tsis yog sab qab teb, ntau tus neeg siv yuav kho lub bracket kom lub module fim sab qab teb tag nrho. Lub hom phiaj yog kom tau txais lub teeb ntau dua thaum lub xyoo. hluav taws xob.
Raws li txoj cai, cov cheeb tsam sib txawv yuav tsum muaj qhov kev xav tau ntawm cov modules kom nyob ze lossis ntau dua li tus nqi latitude hauv zos, tab sis nws kuj yuav tsum tau ua raws li qhov xwm txheej tiag tiag thiab tsis tuaj yeem siv tau los ntawm mechanically. Kev thauj khoom ntawm lub ru tsev, cua tsis kam, cua, nag thiab daus hauv lub xyoo thiab lwm yam kev nyab xeeb yuav tsum tau xav txog. Rau cov chaw nres tsheb loj dua lub ru tsev, nws raug nquahu kom siv lub kaum sab xis me me, thiab qhov kev ncua deb ntawm cov khoom siv square array thiab lub tsev lub ru tsev yuav tsum tsis txhob loj dhau thiab tsim nyog, yog li kom tsis txhob muaj kev ncua deb ntawm qhov kawg ntawm cov square array thiab lub ru tsev loj dhau, uas yuav ua rau muaj kev phom sij rau kev nyab xeeb. Raws li lub sijhawm teeb pom kev zoo, koj tuaj yeem xaiv sab hnub poob lossis sab hnub tuaj, vim hais tias nyob rau hauv cov cheeb tsam no, lub teeb pib ntxov heev los yog lub teeb sab hnub poob yuav siv sij hawm ntev, thiab lub installation yog inclined los ua qhov feem ntau ntawm qhov teeb meem, yog li ntawd lub teeb pom kev zoo nyob rau sab hnub poob. modules tuaj yeem tau txais lub teeb rau lub sijhawm ntev, yog li txhawm rau tsim hluav taws xob txuas ntxiv.
Tsis tas li ntawd, ntau yam ua tau occlusions yog ib qho tseem ceeb uas yuav tsum tau zam hauv kev teeb tsa ntawm cov khoom. Nws tuaj yeem hais tau tias occlusion yog tus tua neeg loj tshaj plaws uas cuam tshuam rau lub zog tsim. Yog tias tsuas yog ib nrab ntawm cov modules nyob rau hauv ib txoj hlua raug thaiv vim shading, yuav luag tsis muaj tam sim no. Yog li ntawd, thaum lub sij hawm installation, sim kom tsis txhob pom tseeb los yog muaj peev xwm shading.
Grid fluctuation yam tseem ceeb yuav tsum tsis txhob ignored
Dab tsi yog "grid fluctuation"? Nws yog qhov xwm txheej uas tus nqi hluav taws xob lossis zaus tus nqi ntawm daim phiaj hluav taws xob hloov pauv ntau dhau thiab nquag, ua rau lub zog tsis ruaj khov rau cov khoom thauj hauv cheeb tsam chaw nres tsheb. Feem ntau, lub substation (substation) yuav tsum tau muab cov khoom siv fais fab hauv ntau qhov chaw. Qee lub davhlau ya nyob twg thauj khoom txawm tias kaum mais deb, thiab muaj kev poob hauv cov kab sib kis. Yog li ntawd, qhov hluav taws xob nyob ze ntawm lub substation yuav raug kho kom siab dua. Nyob rau hauv cov cheeb tsam no, daim phiaj-txuas photovoltaics Lub kaw lus yuav nyob rau hauv standby vim hais tias qhov voltage ntawm cov zis sab yog tsa siab heev; los yog lub photovoltaic system kev koom ua ke ntawm qhov kawg tej thaj chaw deb yuav tsum tsis ua hauj lwm vim ib tug system tsis ua hauj lwm vim yog ib tug tsawg voltage. Lub zog tsim hluav taws xob ntawm lub tshuab hluav taws xob photovoltaic yog tus nqi tsim nyog. Ntev npaum li nws nyob hauv standby lossis kaw, lub zog tsim hluav taws xob tsis tuaj yeem sau tau, thiab qhov tshwm sim yog qhov txo qis hauv kev tsim hluav taws xob. Nyob rau tib lub sijhawm, kev lag luam photovoltaic tau txuas ntxiv boom hauv xyoo tas los no. Hauv qee qhov chaw uas qhov hluav taws xob tseem ceeb yog qhov qub, qhov hluav taws xob ntawm lub tshuab hluav taws xob photovoltaic hauv tib cheeb tsam tau nce ntxiv vim qhov loj ntawm cov khoom siv hluav taws xob photovoltaic muaj peev xwm, thiab qhov muaj peev xwm nqus tau hauv cheeb tsam tau txwv. Cov tshuab hluav taws xob photovoltaic Nws kuj ntsib teeb meem ntawm kab sib chaws hloov pauv. Qhov feem ntau intuitive cuam tshuam ntawm daim phiaj hluav taws xob hloov pauv yog tias lub zog tsim hluav taws xob hloov pauv ntau zaus, kom tsis muaj qhov tso tawm thaum tsim hluav taws xob. Nyob rau hauv txoj kev no, piv nrog lub chaw nres tsheb fais fab nrog ib tug du thiab sib npaug zog tsim nkhaus, lub zog tsim yuav inevitably tsawg.
MTBF
Keeb kwm, lub tswv yim no yog tsom rau cov khoom siv hluav taws xob, tab sis muaj ntau tshaj li ib qho inverter nyob rau hauv lub photovoltaic system. Lub tswv yim no kuj tuaj yeem qiv ntawm no, uas yog, lub sijhawm ntev dua ntawm qhov tsis ua haujlwm ntawm qhov chaw nres tsheb photovoltaic, qhov ruaj khov ntawm qhov chaw nres tsheb fais fab kev ua haujlwm. Lub sijhawm ruaj khov ntev dua, kev ua haujlwm ruaj khov tuaj yeem khaws cia rau lub sijhawm ntev, uas tuaj yeem ua rau cov nyiaj tau los ntawm lub zog ruaj khov.
Qhov txhaum ntawm photovoltaic fais fab nroj tsuag muaj xws li ntau yam ntawm cov ntsiab lus, tsis yog cov faults qhia los ntawm inverter. Cov kab sib chaws hloov pauv tau hais los saum no yog qhov ua txhaum. Tsis tas li ntawd, xws li cov daus thiab plua plav ntawm cov khoom siv, PV thim rov qab kev sib txuas Virtual kev sib txuas, kev laus thiab xoob AC thiab DC cables, lub tuam txhab hluav taws xob tu thiab hluav taws xob hluav taws xob, kev sib txuas virtual hauv AC faib lub thawv, kev mus ncig uas tsis rov qab los, thiab lwm yam., tag nrho cov nyob rau hauv no scope.
Ib qho teeb meem nyob rau hauv ib qho kev txuas yuav ua rau lub chaw nres tsheb fais fab tsis tuaj yeem txuas rau daim phiaj siv hluav taws xob lossis rov tsim hluav taws xob rau hauv daim phiaj; qhov kawg tshwm sim tseem yuav ua rau muaj hluav taws xob tsawg. Yog li ntawd, tom qab kev txhim kho lub photovoltaic fais fab chaw nres tsheb, nyob rau hauv tus txheej txheem ntawm tsis siv neeg ua hauj lwm ntawm lub system, nws yog ib qhov tsim nyog yuav tau teem lub sij hawm soj ntsuam kev khiav hauj lwm thiab txij nkawm, kom tuav lub zog ntawm tag nrho cov sab ntawm lub hwj chim chaw nres tsheb nyob rau hauv lub sij hawm ntawm lub sij hawm, tshem tawm cov yam tsis zoo. uas tuaj yeem cuam tshuam lub sijhawm nruab nrab ntawm qhov tsis ua haujlwm ntawm lub chaw nres tsheb fais fab hauv lub sijhawm, thiab kom ntseeg tau tias cov khoom tso tawm ruaj khov ntawm qhov chaw nres tsheb fais fab.
