Cov tshuab hluav taws xob hnub ci PV uas sawv ntawm nws tus kheej, tseem hu ua cov tshuab hluav taws xob tawm ntawm lub network, yog cov tshuab hluav taws xob tsim hluav taws xob ywj pheej uas tsim los rau cov chaw nyob deb uas tsis muaj kev nkag mus rau lub network. Cov tshuab no lub hom phiaj yog daws cov teeb meem kev muab hluav taws xob hauv cov cheeb tsam tawm ntawm lub network. Lawv qhov kev ntseeg tau raug cuam tshuam los ntawm huab cua, kev xav tau thauj khoom, thiab lwm yam. Txhawm rau txhim kho kev ruaj khov, cov khoom siv khaws cia thiab tswj hwm lub zog feem ntau raug ntxiv.
Kev faib tawm ntawm Standalone Solar PV Systems
Cov tshuab hluav taws xob hnub ci PV uas sawv ntawm nws tus kheej feem ntau yog tsim los ntawm cov vaj huam sib luag hnub ci, cov tswj, thiab cov roj teeb. Rau cov khoom siv AC, kuj xav tau lub inverter. Cov tshuab no tuaj yeem muab faib ua ob hom tseem ceeb: DC lub tshuab hluav taws xob hnub ci PV thiab AC lub tshuab hluav taws xob hnub ci PV.
1. DC Lub Hnub Ci PV Systems
(1) DC Lub Hnub Ci PV Systems Tsis Muaj Roj Teeb
Cov kab ke no muab hluav taws xob rau cov khoom siv DC ncaj qha thaum nruab hnub thaum lub hnub ci muaj. Cov vaj huam sib luag hnub ci txuas ncaj qha rau cov khoom siv, tshem tawm qhov xav tau cov tswj lossis khaws cia hluav taws xob. Qhov kev teeb tsa no txhim kho kev siv hluav taws xob hnub ci los ntawm kev zam kev poob hauv kev hloov pauv hluav taws xob thiab khaws cia. Ib qho kev siv feem ntau yog cov twj tso dej siv hluav taws xob hnub ci.
(2) DC Lub Hnub Ci PV Systems Nrog Cov Roj Teeb
Cov kab ke no suav nrog cov vaj huam sib luag hnub ci, cov tswj hwm them, roj teeb, thiab cov khoom siv DC. Thaum lub sijhawm hnub ci, cov vaj huam sib luag hnub ci muab lub zog rau cov khoom siv thiab them cov roj teeb tib lub sijhawm. Thaum hmo ntuj lossis thaum huab cua tsaus ntuj, cov roj teeb muab lub zog rau cov khoom siv. Cov ntawv thov muaj txij li lub vaj me me hnub ci thiab lub teeb hauv tsev mus rau cov kev daws teeb meem loj rau cov chaw taws teeb sib txuas lus deb, chaw taws teeb microwave relay, thiab kev siv hluav taws xob hauv nroog. Cov kab ke loj dua xav tau cov vaj huam sib luag hnub ci thiab cov txhab roj teeb.
2. Cov Tshuab Hluav Taws Xob AC Hnub Ci PV
(1) AC thiab Hybrid Solar PV Systems
Piv rau cov tshuab DC, cov tshuab AC muaj lub inverter los hloov DC mus ua hluav taws xob AC, uas haum rau cov khoom siv AC. Cov tshuab hybrid tuaj yeem muab hluav taws xob rau ob qho tib si AC thiab DC, ua kom muaj kev siv tau ntau yam.
(2) Cov Tshuab Hluav Taws Xob Hnub Ci PV Uas Muaj Grid-Supplemented
Cov kab ke no feem ntau siv lub zog hnub ci rau kev tsim hluav taws xob, nrog rau lub grid ua qhov chaw ntxiv. Cov vaj huam sib luag hnub ci thiab cov roj teeb tuaj yeem txo qis kom txuag tau nyiaj, siv lub zog hnub ci thaum hnub ci thiab lub zog grid thaum huab cua tsaus ntuj. Txoj hauv kev sib xyaw no txo cov nqi peev txheej thaum pib ua tiav kev txuag hluav taws xob thiab txo cov pa phem. Nws yog ib qho kev daws teeb meem hloov pauv zoo rau kev siv lub hnub ci PV hauv cov cheeb tsam uas muaj ntau tshaj ob feem peb hnub ci txhua xyoo.
Cov ntawv thov ntawm Standalone Solar PV Systems
Cov chaw fais fab hnub ci uas nyob ib leeg, tseem hu ua cov chaw fais fab hnub ci uas nyob ib leeg, yog qhov zoo tagnrho rau cov zos nyob deb nroog, cov kob, thiab lwm qhov chaw uas tsis muaj hluav taws xob uas muaj hnub ci txaus thiab cov neeg siv xav tau ntau. Cov kab ke no feem ntau muaj txij li ntau kilowatts mus txog kaum kilowatts hauv lub peev xwm. Lawv muaj cov vaj huam sib luag hnub ci, roj teeb, inverters, cov kab ke tswj hluav taws xob, thiab cov tes hauj lwm faib hluav taws xob.
Lub tshuab no them roj teeb thaum nruab hnub thaum muab hluav taws xob rau cov twj tso dej thiab cov khoom siv ua haujlwm rau kev ua haujlwm xws li khaws dej thiab tsim khoom. Thaum hmo ntuj, cov roj teeb tso hluav taws xob los ntawm lub inverter kom tau raws li qhov xav tau ntawm cov khoom thauj. Kev tswj hwm roj teeb kom zoo yog qhov tseem ceeb, tshwj xeeb tshaj yog rau kev siv thaum hmo ntuj lossis cov khoom thauj uas tsav los ntawm lub cev muaj zog uas siv hluav taws xob ntau.
Cov tshuab hluav taws xob hnub ci PV uas sawv ntawm nws tus kheej yog cov kev daws teeb meem uas siv tau thiab ruaj khov rau kev daws teeb meem kev tsis txaus fais fab hauv cov cheeb tsam uas tsis muaj hluav taws xob, qhia txog lawv qhov kev ua tau ntau yam thiab muaj peev xwm siv tau rau ntau yam kev siv.
