Daim phiaj-txuas PV txuas nrog kab sib chaws li cas?

Nyob rau hauv cov ntsiab lus ntawm kev hloov hluav taws xob niaj hnub no, kev tsim hluav taws xob photovoltaic, ua ib daim ntawv huv thiab rov ua dua tshiab ntawm lub zog, tau siv ntau thiab ntau dua. Daim phiaj sib txuas ntawm lub chaw nres tsheb fais fab photovoltaic yog cov khoom siv tseem ceeb rau kev sib txuas ntawm photovoltaic system thiab daim phiaj hluav taws xob, thiab nws qhov tseem ceeb yog qhov tseeb.

Ua ntej, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm daim phiaj-txuas txee ntawm photovoltaic fais fab chaw nres tsheb
Kev hloov hluav taws xob hluav taws xob thiab kev sib kis
Hnub ci vaj huam sib luag nyob rau hauv photovoltaic fais fab nroj tsuag hloov hnub ci zog mus rau tam sim no ncaj qha. Tom qab DC tau sau los ntawm lub tsheb npav, nws nkag mus rau hauv inverter. Lub inverter converts ncaj qha tam sim no mus rau alternating tam sim no, thiab nws cov zis alternating tam sim no muaj tib zaus thiab theem raws li daim phiaj fais fab.
Lub zog AC hloov dua siab tshiab los ntawm inverter nkag mus rau hauv daim phiaj-txuas txee ntawm qhov chaw nres tsheb photovoltaic. Lub Circuit Court breaker thiab kev sib cais hloov nyob rau hauv daim phiaj-txuas txee yog lub luag hauj lwm los tswj txoj kev sib kis ntawm hluav taws xob hluav taws xob. Thaum txhua yam zoo li qub, lub Circuit Court breaker raug kaw, thiab cov hluav taws xob hloov pauv tau xa mus rau hauv daim phiaj los ntawm cov kab sib chaws.

Kev ua haujlwm ntawm kev tiv thaiv
Kev tiv thaiv tshaj dhau: Thaum qhov tam sim no tshaj li qhov teeb tsa, cov cuab yeej tiv thaiv overcurrent yuav ua sai sai rau kev txiav tawm ntawm Circuit Court. Qhov no feem ntau yog los ntawm qhov tam sim no transformer txhawm rau txheeb xyuas qhov loj me tam sim no, thaum qhov tam sim no dhau ntawm qhov chaw pib, ua rau lub voj voog tawg.
Kev tiv thaiv overvoltage: Thaum cov hluav taws xob hluav taws xob hluav taws xob siab dhau lawm, cov cuab yeej tiv thaiv overvoltage yuav pib tiv thaiv cov cuab yeej los ntawm kev puas tsuaj vim overvoltage. Kev tiv thaiv overvoltage tuaj yeem ntes cov hluav taws xob hluav taws xob hluav taws xob los ntawm qhov hluav taws xob hloov hluav taws xob, thaum qhov hluav taws xob ntau tshaj li qhov teeb tsa, ua rau lub Circuit Court breaker mus los lossis xa lub tswb nrov.
Kev tiv thaiv undervoltage: Hauv kev sib piv rau kev tiv thaiv overvoltage, thaum daim phiaj hluav taws xob tsawg dhau, cov cuab yeej tiv thaiv undervoltage yuav ua haujlwm los tiv thaiv kev ua haujlwm ruaj khov ntawm cov khoom siv thiab kab sib chaws. Ib yam li ntawd, kev tiv thaiv undervoltage kuj pom cov hluav taws xob hluav taws xob hluav taws xob los ntawm qhov hluav taws xob hloov hluav taws xob, thiab ua rau muaj kev tiv thaiv zoo sib xws thaum qhov hluav taws xob qis dua tus nqi teev.
Kev tiv thaiv luv-Circuit: Thaum muaj kev cuam tshuam luv luv tshwm sim hauv Circuit Court, cov khoom siv tiv thaiv luv luv yuav txiav tawm tam sim ntawd los tiv thaiv kev nthuav dav ntawm qhov txhaum. Kev tiv thaiv luv luv feem ntau ua tiav nrog cov fuses ceev lossis cov hluav taws xob hluav taws xob.

Saib xyuas thiab tswj kev ua haujlwm
Daim phiaj-txuas txee ntawm photovoltaic fais fab chaw nres tsheb yog nruab nrog ntau yam twj paj nruag thiab sensors rau lub sijhawm saib xyuas ntawm qhov voltage, tam sim no, lub zog, zaus thiab lwm yam tsis. Cov kev txwv no tuaj yeem tso tawm rau tus neeg teb xov tooj los ntawm lub vijtsam zaub lossis cov chaw taws teeb sib txuas lus kom nkag siab lub sijhawm ua haujlwm ntawm lub chaw nres tsheb photovoltaic.
Lub kaw lus tswj tau tuaj yeem tswj hwm thiab kho lub chaw nres tsheb fais fab photovoltaic raws li qhov ntsuas ntsuas. Piv txwv li, thaum daim phiaj hluav taws xob siab dhau lawm, lub zog tso zis ntawm qhov chaw nres tsheb photovoltaic tuaj yeem raug txo los ntawm kev tswj hwm; Thaum daim phiaj zaus tsis ruaj khov, qhov tso zis zaus ntawm lub inverter tuaj yeem hloov kho kom nws ua raws li kab sib chaws zaus.
Thib ob, hom kev sib txuas ntawm daim phiaj-txuas txee ntawm qhov chaw nres tsheb photovoltaic thiab lub zog hluav taws xob

Direct kab sib txuas
Direct grid kev twb kev txuas yog hom kev sib txuas tshaj plaws. Nyob rau hauv hom kev sib txuas no, daim phiaj-txuas txee ntawm qhov chaw nres tsheb photovoltaic txuas ncaj qha mus rau qhov nruab nrab lossis qis voltage kab ntawm daim phiaj hluav taws xob los ntawm cov hluav taws xob hluav taws xob, kev hloov pauv thiab lwm yam khoom siv.
Qhov zoo ntawm cov kab sib txuas ncaj qha yog cov qauv yooj yim, tus nqi qis thiab kev ua haujlwm siab. Txawm li cas los xij, hom kev sib txuas no muaj cov kev xav tau siab rau cov khoom siv hluav taws xob zoo ntawm cov chaw nres tsheb photovoltaic, thiab yuav tsum ua kom tau raws li cov kev qhia tshwj xeeb thiab cov kev xav tau ntawm daim phiaj. Nyob rau tib lub sijhawm, kev sib txuas ncaj qha kuj tseem yuav tsum xav txog qhov ruaj khov thiab kev ntseeg siab ntawm daim phiaj hluav taws xob kom tsis txhob muaj kev cuam tshuam tsis zoo ntawm daim phiaj hluav taws xob.

Txuas rau kab sib chaws los ntawm transformer
Kev sib txuas ntawm transformer yog los txuas lub transformer ntawm qhov chaw nres tsheb photovoltaic fais fab thiab daim phiaj fais fab. Transformers tuaj yeem nce lossis txo qhov tso zis hluav taws xob ntawm qhov chaw nres tsheb photovoltaic mus rau qib voltage uas phim cov kab sib chaws.
Qhov zoo ntawm kev sib txuas ntawm kab sib chaws los ntawm kev hloov pauv yog tias nws tuaj yeem txhim kho qhov tso zis hluav taws xob ntawm qhov chaw nres tsheb photovoltaic, txo cov kab poob, thiab tseem ua lub luag haujlwm ntawm kev sib cais thiab kev tiv thaiv. Txawm li cas los xij, txoj kev sib txuas no yog kim heev, occupies ib cheeb tsam loj, thiab qhov poob ntawm lub transformer kuj yuav txo tau tag nrho cov efficiency ntawm photovoltaic fais fab chaw nres tsheb.

Kev sib txuas microgrid
Microgrid yog lub tshuab hluav taws xob me me uas muaj cov khoom siv hluav taws xob sib faib, lub zog cia khoom thiab thauj khoom. Lub chaw tsim hluav taws xob photovoltaic tuaj yeem txuas nrog microgrid los ntawm kab sib txuas nrog cov txee thiab ua ib feem ntawm microgrid.
Txoj kev sib txuas microgrid tuaj yeem txhim kho kev ntseeg tau thiab kev ruaj ntseg ntawm photovoltaic fais fab chaw nres tsheb, tab sis kuj tuaj yeem ua tiav kev siv tau zoo thiab kev tswj xyuas lub zog. Hauv microgrids, cov nroj tsuag photovoltaic tuaj yeem ua haujlwm hauv kev hais kwv txhiaj nrog lwm cov khoom siv hluav taws xob faib kom tau raws li qhov xav tau ntawm cov khoom hauv zos. Thaum lub microgrid txuas nrog rau daim phiaj tseem ceeb, lub zog bidirectional ntws tuaj yeem ua tiav los txhim kho kev siv hluav taws xob.

Installation thiab txij nkawm ntawm daim phiaj-txuas txee ntawm photovoltaic fais fab chaw nres tsheb
Yuav tsum tau nruab
Kev teeb tsa ntawm cov kab sib txuas ntawm cov khoom siv hluav taws xob photovoltaic yuav tsum ua raws li cov cai thiab cov qauv kev nyab xeeb. Qhov chaw teeb tsa yuav tsum nyob hauv qhov chaw qhuav, qhov cua zoo uas yooj yim rau kev khiav lag luam thiab tswj xyuas.
Daim phiaj-txuas txee yuav tsum tau ruaj ntseg ntsia thiab zoo hauv av. Cov cables yuav tsum tau txuas kom raug kom tsis txhob muaj qhov yuam kev xws li luv luv Circuit Court thiab grounding.
Thaum lub sij hawm lub installation txheej txheem, yuav tsum tau them nyiaj mloog mus rau kev tiv thaiv cov cuab yeej thiab meters nyob rau hauv daim phiaj-txuas txee kom tsis txhob muaj kev puas tsuaj. Nyob rau tib lub sijhawm, kev ntsuas hluav taws xob nruj thiab kev debugging yuav tsum tau ua los xyuas kom meej tias cov haujlwm ntawm cov kab hluav taws xob sib txuas yog qhov qub.
txij nkawm
Tshawb xyuas thiab tswj cov kab hluav taws xob sib txuas ntawm lub chaw nres tsheb photovoltaic tsis tu ncua, suav nrog cov khoom siv tu, xyuas cov kev sib txuas cable, kuaj cov cuab yeej tiv thaiv, thiab lwm yam.
Saib xyuas cov xwm txheej khiav ntawm daim phiaj-txuas txee. Yog tias pom muaj teeb meem txawv txav, kho nws raws sijhawm. Piv txwv li, thaum lub Circuit Court breaker yog tripped, lub ntsuas ntsuas yog txawv txav, thiab lwm yam, nws yuav tsum tau soj ntsuam thiab kho tam sim ntawd.
Cov cuab yeej siv thiab cov cuab yeej siv hauv lub txee txuas nrog kab sib txuas yog ntsuas thiab ntsuas tsis tu ncua kom ntseeg tau tias lawv qhov tseeb thiab kev ntseeg tau.
Ntxiv dag zog rau kev tswj hwm kev nyab xeeb ntawm cov kab sib txuas nrog cov khoom siv tiv thaiv kom tsis txhob muaj cov kws tshaj lij los ntawm kev ua haujlwm tsis raug lossis cov khoom puas tsuaj.
