Lub hnub ci photovoltaiccov chaw tsim hluav taws xob tau muab faib uacov kab ke tawm ntawm lub network (ywj pheej)thiab cov kab ke sib txuas nrog grid, thiab tam sim no kuv yuav qhia koj qhov txawv ntawm ob qho no: Thaum cov neeg siv xaiv los teeb tsa cov chaw tsim hluav taws xob hnub ci photovoltaic, lawv yuav tsum xub paub meej tias siv cov chaw tsim hluav taws xob hnub ci photovoltaic off-grid lossis cov chaw tsim hluav taws xob hnub ci photovoltaic txuas nrog grid, kev siv ob lub luag haujlwm tsis zoo ib yam, tau kawg, cov khoom sib xyaw ntawm cov chaw tsim hluav taws xob hnub ci photovoltaic tsis zoo ib yam, tus nqi kuj txawv heev.
(1)Tawm ntawm daim phiajChaw tsim hluav taws xob photovoltaic hnub ci, tseem hu ua chaw tsim hluav taws xob photovoltaic ywj pheej, yog ib lub kaw lus uas tsis vam khom lub zog hluav taws xob thiab ua haujlwm ywj pheej. Nws feem ntau yog tsim los ntawm cov vaj huam sib luag hnub ci photovoltaic, roj teeb khaws cia hluav taws xob, cov tswj hwm them thiab tso tawm, inverters thiab lwm yam khoom. Cov hluav taws xob tso tawm los ntawm lub vaj huam sib luag hnub ci photovoltaic ntws ncaj qha mus rau hauv lub roj teeb thiab khaws cia. Thaum nws xav tau los muab hluav taws xob, cov hluav taws xob ncaj qha hauv lub roj teeb ntws los ntawm lub inverter thiab hloov mus ua 220V alternating current, uas yog ib qho kev rov ua dua ntawm kev them thiab tso tawm. Hom chaw tsim hluav taws xob hnub ci photovoltaic no siv dav vim nws tsis txwv los ntawm thaj chaw. Nws tuaj yeem ntsia thiab siv txhua qhov chaw uas lub hnub ci. Yog li ntawd, nws tsim nyog heev rau thaj chaw deb uas tsis muaj lub zog hluav taws xob, cov kob cais, cov nkoj nuv ntses, cov chaw yug tsiaj sab nraum zoov, thiab kuj tseem siv tau ua cov khoom siv tsim hluav taws xob thaum muaj xwm txheej ceev hauv thaj chaw uas muaj hluav taws xob tsis tu ncua.
Cov chaw fais fab hnub ci photovoltaic uas tsis siv hluav taws xob ua haujlwm yog li ntawm 30-50% ntawm tus nqi ntawm lub tshuab hluav taws xob vim tias lawv yuav tsum muaj roj teeb. Thiab lub neej ua haujlwm ntawm lub roj teeb feem ntau yog 3-5 xyoos, tom qab ntawd yuav tsum tau hloov, uas ua rau tus nqi siv ntau dua. Kev hais lus txog kev lag luam, nws nyuaj rau kom tau txais ntau yam kev txhawb nqa thiab kev siv, yog li nws tsis haum rau kev siv rau hauv cov chaw uas muaj hluav taws xob yooj yim.
Txawm li cas los xij, nws muaj peev xwm ua tau zoo rau cov tsev neeg nyob hauv thaj chaw uas tsis muaj hluav taws xob lossis hluav taws xob tas li. Tshwj xeeb tshaj yog txhawm rau daws qhov teeb meem teeb pom kev zoo thaum lub zog tsis ua haujlwm, koj tuaj yeem siv cov teeb txuag hluav taws xob DC, uas muaj txiaj ntsig zoo heev. Yog li ntawd, cov chaw tsim hluav taws xob photovoltaic hnub ci tsis siv hluav taws xob yog tsim tshwj xeeb rau kev siv hauv thaj chaw tsis muaj hluav taws xob lossis thaj chaw uas muaj hluav taws xob tas li.
(2)Txuas nrog GridLub chaw fais fab hnub ci photovoltaic txhais tau tias nws yuav tsum txuas nrog lub network fais fab pej xeem, uas txhais tau tias lub chaw fais fab hnub ci photovoltaic, lub network fais fab hauv tsev thiab lub network fais fab pej xeem txuas ua ke. Qhov no yog lub tshuab fais fab hnub ci photovoltaic uas yuav tsum vam khom lub network fais fab uas twb muaj lawm kom ua haujlwm. Feem ntau yog tsim los ntawm lub vaj huam sib luag fais fab hnub ci photovoltaic thiab inverter, lub vaj huam sib luag fais fab hnub ci photovoltaic ncaj qha hloov mus rau 220V-380V los ntawm lub inverter.
Cov hluav taws xob hloov pauv kuj siv los ua kom cov khoom siv hauv tsev muaj zog. Thaum cov chaw tsim hluav taws xob hnub ci saum ru tsev tsim hluav taws xob ntau dua li cov khoom siv siv, cov hluav taws xob ntau dhau yuav raug xa mus rau lub network pej xeem. Thaum cov zis ntawm lub chaw tsim hluav taws xob photovoltaic hauv tsev tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom siv hauv tsev, nws yuav rov ua kom tiav los ntawm lub network. Tag nrho cov txheej txheem yog tswj hwm los ntawm kev txawj ntse, tsis muaj tib neeg qhib lossis kaw.
Yog tias koj xav tau cov khoom no, koj tuaj yeem nyem rau ntawm kaum sab xis hauv qab, peb yuav tiv tauj koj sai li sai tau.
