Hnub Ci Photovoltaic Lub Hwj Chim Ua Haujlwm Txoj Cai thiab Txheej Txheem Txheej Txheem

Lub zog hluav taws xob photovoltaic siv lub hnub ci hlwb los hloov lub hnub ci zog rau hauv hluav taws xob hluav taws xob raws li lub hauv paus ntsiab lus ntawm cov nyhuv photovoltaic. Txawm hais tias siv nws tus kheej los yog txuas nrog daim phiaj rau kev tsim hluav taws xob, lub tshuab hluav taws xob photovoltaic feem ntau muaj peb qhov tseem ceeb: cov hnub ci vaj huam sib luag (cov khoom siv), cov tswj thiab inverters. Lawv feem ntau yog tsim los ntawm cov khoom siv hluav taws xob, tab sis tsis suav nrog cov khoom siv tshuab.

Ua hauj lwm hauv paus ntsiab lus ntawm hnub ci photovoltaic fais fab tuag

Hnub ci photovoltaic lub zog tsim hluav taws xob tso siab rau cov khoom siv hluav taws xob hnub ci thiab siv cov khoom hluav taws xob ntawm cov khoom siv semiconductor. Thaum tshav ntuj ci rau ntawm qhov sib txuas ntawm semiconductor PN, ib qho chaw muaj zog hauv electrostatic yog tsim nyob rau hauv thaj chaw PN junction barrier, uas ua rau muaj kev cuam tshuam ntawm cov hluav taws xob tsis sib npaug thiab qhov nyob hauv cheeb tsam lossis qhov tsis sib npaug ntawm cov hluav taws xob thiab qhov uas tsim tawm. sab nraum lub cheeb tsam barrier tab sis diffuse mus rau hauv lub barrier cheeb tsam, nyob rau hauv qhov kev txiav txim ntawm built-in electrostatic teb, tsiv mus nyob rau hauv opposite lus qhia thiab tawm hauv lub barrier cheeb tsam. Raws li qhov tshwm sim, lub peev xwm ntawm thaj av P nce thiab lub peev xwm ntawm thaj av N txo qis, yog li tsim hluav taws xob thiab tam sim no nyob rau hauv sab nraud Circuit Court thiab hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob.

Kev sib xyaw ntawm hnub ci photovoltaic fais fab tuag system

1. Solar cell Cheebtsam

Lub hnub ci cell tsuas tuaj yeem tsim qhov voltage ntawm 0.5V, uas yog qis dua qhov voltage yuav tsum tau siv tiag tiag. Yuav kom ua tau raws li cov kev xav tau ntawm kev siv cov tswv yim, lub hnub ci hnub ci yuav tsum tau txuas rau hauv cov khoom siv. Lub hnub ci module muaj qee tus xov tooj ntawm lub hnub ci txuas nrog cov xov hlau. Piv txwv li, tus naj npawb ntawm lub hnub ci ntawm lub module yog 36, uas txhais tau hais tias lub hnub ci module tuaj yeem tsim qhov hluav taws xob ntawm kwv yees li 17V.

Lub cev lub cev uas raug kaw rau hauv lub hnub ci hlwb txuas nrog cov xov hlau hu ua lub hnub ci cell module. Nws muaj qee yam kev tiv thaiv corrosion, cua-pov thawj, lawg-pov thawj, thiab nag-pov thawj muaj peev xwm, thiab yog dav siv nyob rau hauv ntau yam teb thiab tshuab. Thaum daim ntawv thov teb yuav tsum muaj qhov hluav taws xob ntau dua thiab tam sim no thiab ib qho module tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, ntau lub modules tuaj yeem ua ke rau hauv lub hnub ci cell array kom tau txais qhov xav tau voltage thiab tam sim no.

2. DC / AC inverter

Ib qho khoom siv uas hloov tam sim no ncaj qha mus rau qhov hloov pauv tam sim no. Txij li lub hnub ci hlwb tawm DC lub zog, thiab cov khoom siv dav dav yog AC loads, inverter yog qhov tseem ceeb. Raws li kev khiav hauj lwm hom, inverters tuaj yeem muab faib ua ywj siab ua haujlwm inverters thiab kab sib txuas-sib txuas inverters. Stand-alone inverters yog siv nyob rau hauv stand-alone solar cell lub zog tsim tshuab los muab lub zog rau kev ywj pheej. Grid-connected inverters yog siv los pub lub zog tsim los ntawm lub hnub ci hluav taws xob tsim hluav taws xob ua haujlwm ntawm daim phiaj rau hauv daim phiaj. Inverters tuaj yeem muab faib ua square wave inverters thiab sine wave inverters raws li cov zis waveform.

3. Fais fab faib chav tsim

Txij li cov kab hluav taws xob txuas nrog lub tshuab hluav taws xob tsis muaj roj teeb, lub hnub ci hluav taws xob thiab cov khoom siv hluav taws xob tawm thiab AC thiab DC lub zog xa hluav taws xob, yog tias muaj kev tso cai, lub inverter ntawm daim phiaj hluav taws xob txuas hluav taws xob tuaj yeem muab tso rau hauv chav faib hluav taws xob tsawg. nyob rau ntawm kab sib chaws-kawg taw tes. Txwv tsis pub, tsuas yog tsim kom muaj qhov sib cais Ib chav hluav taws xob qis qis ntawm 4 mus rau 6 m2 txaus.

Hnub ci PV tshuab yog qhov loj thiab peb yog ib lub tuam txhab uas muaj kev paub dhau los hauv kev tsim lub hnub ci PV. Yog xav paub ntxiv txog cov khoom lag luam, thov nyem rau ntawm qhov txuas hauv qab no:
