Cov Ntaub Ntawv Teev Tseg Tshiab hauv Australia Hnub Ci PV Power2020
Txawm hais tias muaj kev ntxhov siab ntawm nws txhua yam, 2020 yog ib lub xyoo zoo tshaj plaws rau hnub ci tau hluav taws xob hauv Australia. Raws li covLub Koom Haum Thoob Ntiaj Teb Lub Zog Hluav Taws Xob (IEA) 'Kev Lag Luam hauv Photovoltaic Applications 2020' daim ntawv qhia, Australia nyob rau No.1 nyob hauv lub ntiaj teb rau ntsia PV rau ib tug nrog 644 watts rau ib tus neeg. Thaum xaus rau 2020, muaj ntau tshaj 2.66 lab Australian cov tsev thiab cov lag luam nrog lub hnub ci ntsa tsev uas ua rau muaj peev xwm ntawm 2.6GW nyob rau hauv tag nrho.
Dab Tsi Teeb Tsim Cov Hluav Taws Xob Hnub Ci?
Qhov tshwj xeeb txoj kev loj hlob nyob rau hauv lub hnub ci PV kuj tseem tau muab qee qhov kev txhawj xeeb. Cov duab muab los ntawm NSW Lub Chaw Saib Xyuas Hluav Taws Kub thiab Tshawb Fawb Tshawb Fawb qhia tias "hluav taws kub uas muaj hnub ci hauv lub xeev tau nce tsib zaug hauv tsib xyoos dhau los." DC cais tawm yog qhov ua rau lub hnub ci hluav taws kub rau:
a. Kev txhim kho tsis zoo
b. Cov khoom siv tsis zoo hauv nruab hnub ci vov sab hauv
c. Lub hnub ci tsis txaus ntseeg PV kev lag luam kev cai. (Tsuas yog Victoria tso cai rau kev kuaj xyuas txhua txoj kab ke ua haujlwm rau tam sim no.)
Standardize DC Isolators
Ib qho xwm txheej hluav taws xob heev tab sis tsis muaj kev phom sij hauv Australia yog los ntawm hnub ci inverter nrog DC hloov hluav taws xob tsim. Hauv Australia, feem ntau ntawm lub hnub ci hloov pauv nrog DC cais sib xyaw ua ke nrog tsis tau ntsib IEC60947.3 3F qhov yuav tsum tau ua. Kev ntsuam xyuas yog pom nyob hauv qab no
Qhov yuav tsum tau ua The3F lockout: (saib cov lus 17 hauv qab) rau kev hloov pauv-DC-hloov hauv qhov inverter raws IEC60947.3:
Ib qho piv txwv ntawm tusDCisolator hloov lub zog F peb kuaj yog 70N:
Nrog ob-ntiv tes ua haujlwm (c), 3F xeem quab yuam yuav tsum yog los ntawm 100N-200N raws li cov tseev kom muaj.
Tab sis peb sim ua haujlwm kov cov cais tawm tuaj yeem kaw thaum nws tsuas yog 72N, uas tsis ua raws li tus qauv IEC60947.3.YogtusDC isolatoris faulty, dej tau nkag mus rau nws los yog cabling yog xoob, yuav muaj ib lub sijhawm ntawm arcing, uas tsim qee zaus hluav taws kub.
Thaum DC rho tawm hluav taws xob sab hauv lub inverter yuav tau txais hluav taws, lub hnub ci inverter yuav yog lwm qhov teeb meem ntawm kev ua kom cov hluav taws sib luag.Yog li ntawd, kev ua kom zoo zoo DC isolator nrog IP66 enclosure zoo heevntawm ib sab lub hnub ci inverter.
Tshem Tawm Kev Ruaj Ntseg Hnub Ci Hluav Taws Xob
Kev ua tau zoo tshaj DC Cheebtsam tuaj yeem xaiv thiab nruab nrog kev saib xyuas zoo tshaj plaws. Txawm li cas los xij, hluav taws xob cable thiab cov yeeb yam kev hloov zuj zus yuav tshwm sim raws li cov kab ke ntawm lub hnub nyoog, uas tuaj yeem ua rau DC arc txhaum. Nws yog qhov tseem ceeb rau kev siv cov khoom siv hnub ci kom muaj kev nyab xeeb uas suav nrog kev lees paub hauv ntiaj teb uas kaw nrawm nrawm nrog lub micro-inverter-based system lossis DC-optimiser-based system.
a.Rapid kaw cov khoom siv yog muaj uas tuaj yeem ntsia ntawm lub ru tsev ib sab ntawm lub hnub cinrog tnws txhob txwm muab cov qauv yooj yim rau cov neeg tua hluav taws raunrawmde-energizetushnub ci system.
b.Ntsuasinverters ntes tag nrho cov hluav taws xob muaj los ntawm txhua lub hnub ci vaj huam sib luag, hloov nws onsite rau AC, thiab tom qab ntawd xa nws mus rau koj lub thawv fuse thiab hluav taws xob daim phiaj.Qhov no ua rau koj lub hnub ci vaj huam sib luag ua haujlwm tau zoo dua vim tias qee qhov ntawm koj lub vaj huam sib luag muaj teeb meem shading, koj cov zis tag nrho yuav tsis raug kev txom nyem.
c. DC lub tshuab ua kom zoo dua tuaj yeem ua kom zoo rau txhua qhov vaj huam sib luag hauv koj lub hnub ci, tsis hais txog kev teeb tsa rau lub hnub, ntxoov ntxoo, lossis ua kev puas tsuaj rau ib lossis ntau dua ntawm cov nplooj ntawv.
Cov teeb meem hluav taws xob hnub ci-cua yuav tsum tau coj mus rau lub sijhawm thaum Australia txaus siab rau nws tus kheej ntawm kev nce toj ntawm hnub ci PV kev teeb tsa. Australia yuav tsum tau txaisnpaj rau tofully collaboin jointeffortsforhnub ci PV kev nyab xeeb.
