Cov hom phiaj tseem ceeb ntawm kev ua haujlwm thiab cov hauv paus ntsiab lus
Tag nrho lub neej kev ua haujlwm thiab kev tswj xyuas cov chaw nres tsheb photovoltaic yog lub hauv paus rau kev ua haujlwm ruaj khov thiab ua haujlwm tau zoo. Nws cov hom phiaj tseem ceeb thiab cov ntsiab cai tsim lub hauv paus ntawm kev ua haujlwm, hais txog ob qho tib si technical thiab cov tswv yim qhov ntev.
1. Lub Hom Phiaj Ua Haujlwm tseem ceeb
Maximizing Fais fab Generation Efficiency
Txheej txheem O&M cov tswv yim ua kom pom lub zog tawm los. Plua plav sib sau ua ke tuaj yeem txiav tawm los ntawm 5% -30%. Kev tu txhua hnub thiab kev tu xyuas kom qis dua qhov muaj peev xwm ntawm thermal runaway. Kev tshawb fawb qhia tias cov khoom qias neeg tuaj yeem tsim cov chaw kub, uas ua rau muaj kev ua haujlwm tsawg thiab muaj kev phom sij.
Cov ntsiab lus tseem ceeb suav nrog kev ua kom huv huv, khoom siv parameter optimization, thiab kev tswj hwm ib puag ncig.
Ua kom muaj kev ntseeg tau ntawm cov cuab yeej siv
Cov tshuab photovoltaic suav nrog ntau cov khoom siv hluav taws xob thiab cov khoom siv kho tshuab. Kev tiv thaiv kev saib xyuas (feem ntau yog cov bolt torque checks thiab cable sib koom kuaj xyuas) tso cai rau kev txheeb xyuas qhov kev pheej hmoo latent. Cov teeb meem phom sij, xws li cov khoom siv tsis raug DC crimped (ua tiav nrog cov cuab yeej tsis ua raws li -), tuaj yeem tsim arcing thiab hluav taws kub, yog li yuav tsum tau ua raws li cov qauv tsim nyog.
Tswj cov nuj nqis Lifecycle
Nrog rau lub neej ntev tshaj 25 xyoo, Kev Ua Haujlwm thiab Kev Kho Tus Nqi yog feem ntau nyob rau hauv thaj tsam ntawm 15% mus rau 25% ntawm LCOE, yog li nws yog ib qho tseem ceeb uas yuav tsum xav txog seb peb tuaj yeem ua ke kev nqis peev hauv kev tiv thaiv, xws li kev siv drone tshuaj ntsuam xyuas kev nyab xeeb thiab kho qhov ua tsis tiav. Cov tshuab ntxuav tu tsis siv neeg tshem tawm qee qhov ntawm cov nqi dej thiab txo qhov kev txhawj xeeb ntawm kev nyab xeeb ntawm cov neeg ua haujlwm ntawm qhov chaw nyob deb ntawm cov roob. Cov tshuab ntxuav tshuab siv tshuab siv li 30% dej tsawg dua li kev ntxuav tes.
2. Cov ntsiab cai tseem ceeb
Kev tiv thaiv-Thawj Txoj Kev
Txhawm rau kom muaj kev ua haujlwm zoo ib yam, tsim cov txheej txheem txheej txheem rau kev ua haujlwm xws li daim ntawv tso cai ua haujlwm, kuaj xyuas cov cuab yeej, thiab cov kev xeem niaj hnub.
Cov ntaub ntawv -Txoj Kev Txiav Txim Siab
Rau kev paub txog kev xaiv, siv cov tshuab ua ke los sau cov ntaub ntawv tam sim no ntawm cov zis thiab ib puag ncig. Kev soj ntsuam kev kwv yees tuaj yeem pab kho cov phiaj xwm kev saib xyuas los ntawm kev pom cov khoom tsis muaj zog los ntawm txoj hauv kev xws li IV nkhaus thiab kev tsom xam thermal.
Standardization thiab ua raws
Txhawm rau ua kom tau raws li kev tswj hwm kev xav tau, ua raws li cov qauv zoo li GB / T 38335-2019, nrog rau cov qauv kev lag luam cuam tshuam. Khaws cov ntaub ntawv ntxaws ntxaws ntawm kev teeb tsa lub cuab yeej, pib ua haujlwm, thiab ua haujlwm tu.
Rau kev nyab xeeb, ua tau raws li GB 26859/26860 tus qauv rau kev ua haujlwm hluav taws xob. Muab tso rau hauv qhov chaw tiv thaiv arc flash, lub tshuab hauv av (tsawg dua lossis sib npaug ntawm 4Ω), thiab npaj rau kev teb rau hluav taws kub lossis hluav taws xob txaus ntshai.
Inverter dej ingress kev kho
Xyuas kom meej tias lub sealing ntsaws uas tuaj nrog lub inverter yog ruaj khov. Tom qab qhib lub hau, xyuas seb cov hlua khi puas zoo li qub, thiab ceev cov ntsia hlau thaum kaw lub hau.
Tighten lub nplhaib sealing dej ntawm lub AC davhlau ya nyob twg.
Yog tias lub vijtsam pos huab, feem ntau nws yuav ploj mus ntawm nws tus kheej tom qab huab cua zoo dua, tab sis qhov kev sib khi inverter tseem yuav tsum tau kuaj xyuas.
Lub inverter yog qhov zoo tshaj plaws ntsia ntawm qhov chaw siab lossis hauv qab eaves los tiv thaiv cov dej nag ncaj qha.
Txuas cov hlau ntawm cov khoom siv hluav taws xob rau hauv av, thiab qhov sib txuas yuav tsum tau welded los ntawm hluav taws xob vuam, thiab soldering yog txwv.
Yog tias vuam tsis zoo, riveting lossis bolting yog lwm txoj hauv kev, muab qhov chaw sib tiv tauj tshaj 10 square centimeters. Rau hauv av, lub cev yuav tsum tau faus ntawm 0.5 thiab 0.8 meters tob, nrog ceev faj compaction ntawm backfill.
Xaiv lub chaw nres tsheb fais fab photovoltaic nrog kev ntseeg siab thiab lub koob npe zoo. Cov cuab yeej tseem ceeb yuav tsum muaj DC arc tiv thaiv thiab kaw nrawm nrawm.
Kev tsim kho thiab kev teeb tsa yuav tsum yog tus qauv. Nrhiav cov chaw tsim khoom siv hluav taws xob photovoltaic txhim khu kev qha kom tsis txhob muaj teeb meem xws li cov khoom tawg thiab cov xaim tsis zoo thaum tsim kho.
Ua haujlwm tu thiab tshuaj xyuas kom tsis tu ncua txhawm rau tiv thaiv cov cuab yeej los ntawm kev ua haujlwm tsis zoo, dhau - kev pabcuam thiab overload. Khaws cov khoom siv hluav taws xob photovoltaic, inverter thiab cov thawv xa khoom qhib. Yog tias muaj cov khib nyiab pov tseg, nws yuav tsum tau muab ntxuav kom huv si raws sijhawm.
Xaiv lub chaw nres tsheb fais fab photovoltaic txhim khu kev qha los xyuas kom meej cov khoom zoo thiab kev tsim kho zoo thiab zam qhov teeb meem ntawm qhov tsis txaus counterweight.
Thaum xaiv ib qhov chaw, xav txog qhov xwm txheej ntawm cov cua muaj zog, tsim nyog ua kom lub counterweight thiab ntxiv dag zog rau kev ruaj ntseg ntawm lub bracket.
