Cov Txheej Txheem Thiab Kev Ua Haujlwm Ntawm Cov Hluav Taws Xob Hluav Taws Xob Photovoltaic

Lub tshuab hluav taws xob photovoltaic yog siv cov nyhuv photovoltaic, lub hnub ci zog rau hauv kev tsim hluav taws xob, tuaj yeem muab faib ua kev ywj pheej photovoltaic lub zog tsim hluav taws xob, kab sib txuas nrog photovoltaic lub zog tsim hluav taws xob thiab faib hluav taws xob photovoltaic zog tsim system. Cov lus tom ntej no yuav muab cov lus qhia luv luv rau koj txog kev muaj pes tsawg leeg thiab kev ua haujlwm ntawm photovoltaic fais fab tuag system thiab cov:
1. Photovoltaic modules
Photovoltaic modules yog lub hauv paus tseem ceeb ntawm tag nrho cov tsim hluav taws xob tsim hluav taws xob, uas yog tsim los ntawm photovoltaic modules los yog photovoltaic modules ntawm txawv specifications txiav los ntawm laser txiav machine lossis steel hlau txiav machine. Vim tias tam sim no thiab qhov hluav taws xob ntawm ib lub xov tooj ntawm tes photovoltaic tsawg heev, nws yog ib qho tsim nyog yuav tsum tau txais high voltage hauv series ua ntej, thiab tom qab ntawd tau txais cov tam sim no siab nyob rau hauv parallel, tso zis los ntawm ib tug ncej raj (kom tiv thaiv tam sim no input rov qab), thiab ces ntim rau hauv ib lub stainless hlau, txhuas los yog lwm yam uas tsis yog-hlau thav duab, nruab lub iav saum toj no thiab lub nraub qaum sab nraub qaum, sau cov nitrogen, thiab foob. Lub photovoltaic modules tau ua ke nyob rau hauv series thiab thaum uas tig mus rau ib tug photovoltaic module array, kuj hu ua photovoltaic array.
Lub hauv paus ntsiab lus ua haujlwm: Lub hnub ci ci ntawm qhov sib txuas ntawm semiconductor PN, tsim lub qhov tshiab-electron khub, nyob rau hauv qhov kev txiav txim ntawm PN hlws ris hluav taws xob teb, lub qhov ntws los ntawm thaj av p mus rau thaj tsam n, cov hluav taws xob ntws los ntawm thaj tsam n mus rau thaj tsam p, thiab tam sim no yog tsim tom qab lub Circuit Court yog switched. Nws lub luag haujlwm yog hloov lub hnub ci zog rau hauv hluav taws xob, thiab xa mus rau lub roj teeb rau kev khaws cia, lossis txhawb nqa cov haujlwm ua haujlwm.
Yam khoom:
① monocrystalline silicon: photoelectric hloov pauv tus nqi ≈ 18%, siab li 24%, yog qhov hloov pauv siab tshaj plaws ntawm tag nrho cov photovoltaic modules, feem ntau siv cov iav tempered thiab waterproof resin ntim, ruaj, kev pab cuam lub neej feem ntau ncav cuag 25 xyoo.
② polysilicon: photoelectric hloov pauv tus nqi ≈ 14%, thiab cov txheej txheem ntawm monocrystalline silicon zoo ib yam, qhov sib txawv ntawm polysilicon yog tias tus photoelectric hloov dua siab tshiab qis dua, tus nqi qis dua, lub neej luv dua, tab sis cov khoom siv polysilicon yog qhov yooj yim rau kev tsim khoom, txuag hluav taws xob noj, tus nqi qis, yog li nws tau tsim muaj zog heev.
③ Amorphous silicon: photoelectric hloov pauv tus nqi ≈ 10%, thiab monocrystal silicon thiab polysilicon ntau lawm txoj kev sib txawv kiag li, yog nyias zaj duab xis hnub ci cell, txheej txheem yog heev yooj yim, silicon cov khoom noj yog tsawg heev, tsawg zog noj, nws lub ntsiab kom zoo dua yog nyob rau hauv cov teeb meem uas tsis muaj teeb meem kuj tsim hluav taws xob.
2, xws li (off-grid system siv)
Lub photovoltaic maub los yog ib qho khoom siv tswj tsis siv neeg uas tuaj yeem tiv thaiv lub roj teeb ntawm overcharging thiab overdischarging. Siv high-speed CPU microprocessor thiab high-precision A / D analog-to-digital converter, nws yog microcomputer cov ntaub ntawv tau txais thiab kev tswj xyuas qhov system, uas tuaj yeem ceev thiab lub sijhawm ua haujlwm tam sim no ntawm photovoltaic system, tau txais Cov ntaub ntawv ua haujlwm ntawm PV chaw nres tsheb txhua lub sijhawm, thiab khaws cov ntaub ntawv keeb kwm ntawm PV chaw nres tsheb kom ntxaws. Nws muab lub hauv paus raug thiab txaus rau kev ntsuam xyuas qhov tsim nyog ntawm PV system tsim thiab kuaj qhov kev ntseeg siab ntawm qhov system tivthaiv zoo. Nws kuj muaj cov ntaub ntawv sib txuas lus sib txuas lus, uas tuaj yeem tswj hwm hauv nruab nrab thiab tswj hwm ntau lub PV system sub-station.
3. Inverter
Inverter yog ib qho khoom siv uas hloov cov tam sim no ncaj qha tsim los ntawm photovoltaic fais fab tiam mus rau hauv alternating tam sim no, photovoltaic inverter yog ib qho tseem ceeb ntawm cov khoom sib npaug hauv photovoltaic array system, thiab tuaj yeem siv nrog cov khoom siv hluav taws xob AC. Hnub ci inverters muaj kev ua haujlwm tshwj xeeb nrog cov photovoltaic arrays, xws li lub zog taw tes nrhiav thiab kev tiv thaiv Island.
Hnub ci inverters tuaj yeem muab faib ua peb pawg hauv qab no:
① Independent inverter: Siv nyob rau hauv ib qho kev ywj pheej, lub photovoltaic array tsub lub roj teeb, thiab lub inverter yuav siv DC voltage ntawm lub roj teeb raws li lub zog qhov chaw. Ntau tus neeg inverters kuj muaj cov roj teeb sib xyaw uas tuaj yeem them lub roj teeb nrog AC lub zog. Feem ntau, xws li inverters tsis tuaj rau hauv kev sib cuag nrog daim phiaj hluav taws xob, thiab yog li tsis tas yuav muaj kev tiv thaiv kev ua haujlwm.
② Grid-connected inverter: cov zis hluav taws xob ntawm lub inverter tuaj yeem xa rov qab mus rau kev lag luam AC fais fab mov, yog li cov zis chord nthwv dej yuav tsum zoo ib yam li theem, zaus thiab qhov hluav taws xob ntawm lub zog hluav taws xob. Daim phiaj-txuas inverter yuav muaj kev ruaj ntseg tsim uas cia li tua cov zis yog tias nws tsis txuas nrog lub hwj chim mov. Yog tias daim phiaj hluav taws xob dhia dhia, daim phiaj-txuas inverter tsis muaj lub zog ua haujlwm.
(3) Standby roj teeb inverter: ib qho tshwj xeeb inverter, los ntawm lub roj teeb raws li nws lub hwj chim mov, nrog lub roj teeb charger kom them lub roj teeb, yog hais tias muaj zog heev, yuav recharged mus rau lub AC fais fab tuag. Lub inverter no tuaj yeem muab AC lub zog rau lub nra hnyav thaum lub phiaj xwm hluav taws xob raug kaw, yog li nws yuav tsum muaj kev tiv thaiv kev ua haujlwm.
4, roj teeb (tsis xav tau rau kab sib txuas nrog)
Lub roj teeb yog cov cuab yeej khaws cia hluav taws xob hauv lub tshuab hluav taws xob photovoltaic. Tam sim no, muaj plaub hom roj teeb uas tsis muaj hmoov lead-acid, cov roj teeb txhuas-acid zoo tib yam, roj teeb colloidal thiab alkaline nickel-cadmium roj teeb, thiab cov roj teeb uas tsis muaj kua qaub thiab cov roj teeb colloidal tau siv dav.
Lub hauv paus ntsiab lus ua haujlwm: Thaum nruab hnub, lub hnub ci ci ntawm photovoltaic module, tsim hluav taws xob DC, hloov lub teeb lub zog rau hauv hluav taws xob, thiab tom qab ntawd xa mus rau tus tswj hwm, tom qab kev tiv thaiv overcharge ntawm tus maub los, hluav taws xob los ntawm photovoltaic module raug xa mus. mus rau lub roj teeb cia, siv thaum xav tau.
