daws qhov teeb meem ntawm Inverter thiab Grid Connection Point Voltage los ntawm ntau lub kaum sab xis
Thaum lub tshuab hluav taws xob photovoltaic faib tag nrho thiab lub peev xwm piv tau nce mus txog qee qhov kev faib ua feem, nws yooj yim los ua teeb meem ntawm qhov hluav taws xob overrun. Voltage overruns tsis tsuas yog cuam tshuam rau cov teeb meem hluav taws xob zoo, tab sis kuj txwv kev nkag mus ntawm photovoltaics hauv kev faib network. Nyob rau hauv cov lus teb rau qhov hluav taws xob overruns, cov tuam txhab hluav taws xob hluav taws xob tau tshaj tawm cov kab sib txuas sib txuas cov kev qhia tshwj xeeb rau cov tshuab hluav taws xob photovoltaic. Kuj tseem muaj cov kev daws teeb meem hauv kev lag luam, xws li kho qhov hluav taws xob ntawm qhov chaw sib txuas ntawm kab sib chaws lossis ntxiv cov khoom siv hluav taws xob tshiab los ntawm inverter tswj kev daws teeb meem. Hauv tsab xov xwm no, peb yuav nthuav tawm cov teeb meem hluav taws xob ntawm photovoltaic thiab kab sib txuas cov ntsiab lus rau txhua tus.
01 Puas yog daim phiaj-khi inverter qhov hluav taws xob lossis qhov chaw tam sim no?
Ua ntej, peb yuav tsum nkag siab txog hom inverter fais fab mov, uas yuav pab kom nkag siab qhov cuam tshuam ntawm daim phiaj ntawm lub inverter. Tsis muaj qhov tsis ntseeg tias daim phiaj-txuas inverter yog lub zog tsim hluav taws xob thiab yog nyob rau qhov tam sim no. Tus yam ntxwv ntawm qhov tam sim no yog qhov kev tiv thaiv sab hauv yog infinite, thiab cov zis tam sim no yog tswj los ntawm cov khoom siv hauv algorithm. Qhov voltage thiab zaus yog txiav txim los ntawm sab nraud Circuit Court (grid). Cov yam ntxwv ntawm qhov tam sim no xav kom qhov chaw tam sim no tsis tuaj yeem qhib tau (daim phiaj tsis tuaj yeem ua tsis tau), thiab qhov chaw tam sim no tuaj yeem siv ua ke.
Cov yam ntxwv ntawm qhov hluav taws xob qhov hluav taws xob yog tias qhov kev tiv thaiv sab hauv yog xoom thiab cov zis hluav taws xob tsis tu ncua. Tam sim no thiab nws cov kev taw qhia yog txiav txim siab los ntawm qhov chaw voltage thiab sab nraud Circuit Court. Cov yam ntxwv ntawm qhov hluav taws xob qhov hluav taws xob xav tau tias qhov hluav taws xob tsis tuaj yeem raug luv luv.
Lub tswv yim ua haujlwm ntawm daim phiaj-txuas inverter yog tso siab rau kev txhawb nqa nruj ntawm qhov voltage thiab zaus muab los ntawm daim phiaj hluav taws xob loj. Lub sijhawm no, qhov kev hloov pauv ntawm cov khoom thauj, qhov hluav taws xob thiab zaus cuam tshuam hauv daim phiaj hluav taws xob yog tag nrho los ntawm daim phiaj hluav taws xob loj, thiab cov khoom siv hluav taws xob faib tsis tas yuav xav txog qhov voltage thiab zaus tswj. .
Cov zis hluav taws xob ntawm photovoltaic daim phiaj-txuas inverter yog txiav txim los ntawm daim phiaj. Thaum cov kab hluav taws xob hluav taws xob tshaj qhov inverter qhov kev khiav hauj lwm voltage ntau, lub inverter yuav poob thiab kaw. Thaum cov kab hluav taws xob hluav taws xob nyob hauv inverter qhov kev khiav hauj lwm voltage ntau, lub inverter yuav ua hauj lwm ib txwm.
Daim phiaj hluav taws xob muaj qee qhov kev xav tau rau cov khoom siv hluav taws xob zoo los ntawm ntau hom inverters, thiab muaj qee qhov sib txawv ntawm qhov sib txawv specifications thiab txawv inverters.
02 Qhov sib txawv ntawm chav kawm A thiab chav kawm B inverters
Class A inverters yog ze ze rau cov kev xav tau ntawm cov phiaj xwm pej xeem, thiab chav kawm B inverters feem ntau yog siv hauv cov tshuab hluav taws xob photovoltaic faib. Nws muaj cov yam ntxwv ntawm cov hluav taws xob tsis tshua muaj hluav taws xob sib txuas, tsis muaj kev sib txuas nrog cov phiaj xwm pej xeem, thiab cuam tshuam me me rau ntawm daim phiaj.
03 Cov kev daws teeb meem rau cov teeb meem kab hluav taws xob sib txuas
a. Inverter tswj lub zog
Lub inverter tuaj yeem kho thiab tswj lub zog ua haujlwm thiab cov hluav taws xob reactive tawm los ntawm photovoltaic thaum lub sij hawm sib txuas ntawm daim phiaj, thiab tuaj yeem kho qhov voltage ntawm daim phiaj sib txuas los ntawm kev tswj lub hwj chim.
b. Reactive zog them nyiaj ntaus ntawv
Qhov tseem ceeb ntawm reactive fais fab nyiaj them rau lub zog hluav taws xob tau them ntau dua thiab ntau dua, thiab cov khoom siv hluav taws xob reactive yuav tsum tau siv kom tsim nyog. Nws ua lub luag haujlwm tseem ceeb hauv kev kho cov phiaj xwm hluav taws xob, txhim kho cov khoom siv hluav taws xob zoo, tiv thaiv kev cuam tshuam kev sib raug zoo, thiab ua kom muaj kev nyab xeeb ntawm daim phiaj.
c. Configure lub zog cia
1) Lub zog cia tuaj yeem daws qhov teeb meem ntawm peb theem voltage imbalance.
2) Los ntawm cov lus teb ceev ceev ntawm lub zog-hom lub zog cia, qhov teeb meem ntawm qhov hluav taws xob ntawm qhov hluav taws xob flicker thiab sag kuj tuaj yeem them nyiaj.
3) Lub zog cia tuaj yeem ua cov nyiaj them rov qab zog thiab txhim kho lub zog yam tsis muaj kev cuam tshuam photovoltaic active zog tso zis.
Nrog rau kev nce hauv kev faib ua feem ntawm cov khoom siv hluav taws xob, daim phiaj hluav taws xob yuav tsum ua kom tag nrho cov kev npaj rau kev faib hluav taws xob thiab cov phiaj xwm hluav taws xob, suav cov peev txheej ntawm cov xaim hluav taws xob ntawm txhua qib, ntxiv dag zog rau kev faib hluav taws xob pab pawg ntsuas, pab pawg tswj hwm thiab pab pawg hloov kho tshuab, on-load peev xwm tswj, voltage tswj thiab tis. cov thev naus laus zis tseem ceeb xws li hluav taws xob. Peb tos ntsoov rau kev qhia txog cov qauv kev sib koom ua ke rau daim phiaj siv hluav taws xob, uas tuaj yeem daws cov kev xav tau tshwj xeeb rau cov khoom siv hluav taws xob ntau, thiab ua haujlwm ua ke los tsim lub zog tshiab.
Peb lub tuam txhab feem ntau yog muab thiab daws cov ntse wireless saib xyuas thiab tswj cov kev daws teeb meem nrog tus nqi qis, kev siv tshuab siab, thiab kev sib txuas lus ruaj khov. Peb pawg tswj hwm tau nyob hauv qhov kev lag luam kev lag luam no rau ntau tshaj 20 xyoo. Yog tias koj txaus siab rau IoT-raws li cov chaw taws teeb tswj, IoT-raws li kev tswj hwm lub zog, hluav taws xob hluav taws xob them pawg, thiab lwm yam. Thov koj xav tiv tauj peb.
