2017 yog lub npe hu ua thawj xyoo ntawm kev faib PHOTOVOLTAIC ntawm Tuam Tshoj, qhov nce txhua xyoo ntawm kev faib PV nruab muaj peev xwm yog ze li ntawm 20GW, nws kwv yees tias tsev neeg faib PV tau nce ntau dua 500,000 tsev neeg, ntawm zhejiang, Shandong ob lub xeev. tsev PV installation yog ntau tshaj 100,000 tsev neeg.
Raws li paub rau txhua tus, piv nrog cov chaw nres tsheb loj hauv av, ib puag ncig ntawm lub ru tsev faib hluav taws xob photovoltaic fais fab chaw nres tsheb yog qhov nyuaj dua, txhawm rau kom tsis txhob muaj kev cuam tshuam ntawm kev cuam tshuam xws li parapet, cov tsev nyob ib puag ncig, nyiaj siv ua haujlwm cable, ru tsev chimney, hnub ci. lub tshuab rhaub dej, thiab kom tsis txhob muaj teeb meem ntawm qhov sib txawv ntawm lub ru tsev nruab hnub nrig yog qhov tsis sib xws, thaj chaw muaj lub ru tsev yuav raug txo kom tsawg thiab lub peev xwm nruab yuav raug txwv.
Yog tias qhov kev tiv thaiv no tsis raug zam, lub chaw nres tsheb fais fab yuav ua rau muaj kev sib txuam thiab tsis sib xws vim qhov thaiv thaiv lossis teeb pom kev tsis sib haum, thiab tag nrho lub zog tsim hluav taws xob ntawm lub chaw nres tsheb fais fab yuav raug txo.Raws li cov ntaub ntawv tshawb fawb, cov duab ntxoov ntxoo hauv zos ntawm photovoltaic modules yuav txo qis tag nrho cov khoom tsim hluav taws xob ntau dua 30%.
Raws li PVsyst qauv kev soj ntsuam, vim yog cov yam ntxwv ntawm photovoltaic series, yog tias lub zog tsim hluav taws xob ntawm ib qho photovoltaic module raug txo los ntawm 30%, lub zog tsim hluav taws xob ntawm lwm cov khoom hauv tag nrho cov pab pawg kuj yuav poob rau tib theem qis, uas. yog luv luv board nyhuv ntawm cov ntoo chim nyob rau hauv lub photovoltaic pab pawg neeg series system.
Raws li qhov xwm txheej saum toj no, nws raug nquahu kom nruab PV lub zog ua kom zoo dua qub, uas tuaj yeem tswj nws tus kheej lub siab nce thiab poob ntawm txhua PV module, daws cov teeb meem ntawm kev sib txuas thiab tsis sib xws ntawm pawg photovoltaic tshwm sim los ntawm cov kab nrib pleb, kub kub, duab ntxoov ntxoo occlusion, sib txawv huv si, inconsistent orientation thiab teeb pom kev zoo, thiab tuaj yeem txhim kho lub zog tag nrho ntawm lub cev.
Peb kis tau siv los ntsuas qhov ua tau zoo ntawm photovoltaic zog optimizer.
8KW ru tsev fais fab chaw nres tsheb, lub generating peev xwm ntawm optimized cheeb tsam tau nce 130%, generated ib tug ntxiv 6 KWH ntawm hluav taws xob txhua hnub.
Lub chaw nres tsheb hluav taws xob hauv tsev 8KW yog tsim rau hauv pem teb thib peb ntawm lub tsev nyob.Qee cov khoom tau nruab rau ntawm lub sam thiaj thiab qee cov khoom siv tau nruab rau ntawm cov nplais saum npoo.
Lub roj teeb module yog ntxoov ntxoo los ntawm lub rhaub dej thiab cov dej ntauwd uas nyob ib sab, uas yog simulated los ntawm PVsyst rau 12 lub hlis ntawm lub xyoo.Raws li qhov tshwm sim, nws tsim 63% hluav taws xob tsawg dua li qhov yuav tsum tau, tsuas yog 8.3 KWH ib hnub,
Tom qab lub optimizer tau nruab rau cov koob no, los ntawm kev sib piv lub zog tsim nyob rau hauv 10 hnub ci hnub ua ntej thiab tom qab kev teeb tsa, kev tshuaj xyuas yog raws li hauv qab no:
Thawj hnub ntawm kev ua haujlwm ntawm lub optimizer yog Lub Kaum Ob Hlis 20, tib lub sijhawm, grey ib feem ntawm lub zog tsim hluav taws xob ntawm pawg sib piv yog ntxiv rau kev tshuaj xyuas kom tsis txhob cuam tshuam cov hluav taws xob, qhov kub thiab txias thiab lwm yam cuam tshuam.Tom qab kev teeb tsa ntawm lub optimizer, lub zog tsim qhov sib piv yog 130%, thiab qhov nruab nrab lub zog txhua hnub yog 6 KWH.
5.5KW lub tsev hluav taws xob hauv tsev, lub zog tsim hluav taws xob ntawm pawg optimized tau nce 39.13%, tsim hluav taws xob ntxiv 6.47 KWH txhua hnub.
Rau 5.5kW qhov chaw nres tsheb fais fab hauv tsev tau muab tso rau hauv kev ua haujlwm hauv xyoo 2017, ob txoj hlua tau cuam tshuam los ntawm qhov chaw nyob ntawm cov ntoo nyob ib puag ncig, thiab lub zog tsim hluav taws xob qis dua qhov qub.
Raws li qhov tseeb tiv thaiv qhov teeb meem ntawm qhov chaw, kev ua qauv thiab kev tsom xam yog nqa tawm hauv pvsyst.Ob txoj hlua no muaj tag nrho ntawm 20 photovoltaic modules, uas yuav muab ntxoov ntxoo rau 10 lub hlis ntawm lub xyoo, txo qis tag nrho lub zog tsim ntawm lub cev.Txhawm rau ua kom tiav, lub tshuab hluav taws xob photovoltaic optimizer tau teeb tsa ntawm ob ntu ntawm 20 modules hauv qhov project site.
Tom qab 20 lub tshuab hluav taws xob photovoltaic optimizers tau teeb tsa ntawm ob txoj hlua, los ntawm kev sib piv lub zog tsim hluav taws xob hauv 5 hnub tshav ntuj ua ntej thiab tom qab kev teeb tsa, kev tshuaj xyuas yog raws li hauv qab no:
Thawj hnub ntawm kev ua haujlwm ntawm lub optimizer yog Lub Kaum Ob Hlis 30, tib lub sijhawm, qhov grey ntawm lub zog tsim hluav taws xob ntawm pawg sib piv yog ntxiv rau kev tshuaj xyuas kom tsis suav cov hluav taws xob, qhov kub thiab txias thiab lwm yam cuam tshuam.Tom qab kev teeb tsa ntawm lub optimizer, lub zog tsim qhov sib piv yog 39.13%, thiab qhov nruab nrab lub zog txhua hnub yog 6.47 KWH.
2MW centralized fais fab chaw nres tsheb, lub zog tsim hluav taws xob ntawm plaub pawg nyob rau hauv qhov chaw optimization yog nce los ntawm 105.93%, generated ib tug ntxiv 29.28 KWH ntawm hluav taws xob txhua hnub.
Rau 2MW centralized roob hluav taws xob chaw nres tsheb tau muab tso rau hauv kev ua haujlwm hauv xyoo 2015, cov duab ntxoov ntxoo ntawm qhov chaw tiv thaiv yog qhov nyuaj, uas feem ntau muab faib ua peb ntu: lub zog ncej thaiv, ntoo thaiv thiab me me dhau ntawm sab xub ntiag thiab sab nraub qaum ntawm cov khoom.Sab pem hauv ntej thiab nram qab kab thaiv ntawm cov khoom yuav tshwm nyob rau lub caij ntuj no vim lub hnub qhov siab lub kaum sab xis yuav qis, tab sis tsis nyob rau hauv lub caij ntuj sov.Ncej shading thiab ntoo shading tshwm sim thoob plaws hauv lub xyoo.
Tus qauv ntawm tag nrho cov kab ke yog tsim nyob rau hauv pvsyst raws li tus qauv tsis ua hauj lwm ntawm lub Cheebtsam thiab inverters nyob rau hauv lub system, qhov project qhov chaw thiab cov xwm txheej tshwj xeeb ntawm kev ntxoov ntxoo.Nyob rau hauv tshav ntuj hnub, lub linear poob ntawm lub teeb hluav taws xob yog 8.9%.Tus nqi theoretical tsis tuaj yeem tau txais vim qhov poob ntawm lub zog tsis sib haum xeeb tshwm sim los ntawm qhov tsis sib xws.
Raws li qhov chaw nyob, plaub txoj hlua raug xaiv, 22 photovoltaic fais fab optimizers raug ntsia rau hauv txhua txoj hlua, thiab tag nrho ntawm 88 optimizers raug teeb tsa.Los ntawm kev sib piv cov khoom siv hluav taws xob ua ntej thiab tom qab kev teeb tsa thiab lub zog tsim hluav taws xob ntawm cov kab uas nyob ib sab uas tsis tau teeb tsa optimizer, kev tshuaj xyuas yog raws li hauv qab no:
Nyob rau hauv tshav ntuj hnub, qhov cuam tshuam ntawm huab cua irradiation yuav tsum tau txo, thiab grey ib feem ntawm lub hwj chim tiam ntawm kev sib piv pab pawg series yuav tsum tau ntxiv rau kev soj ntsuam kom tshem tawm cov hluav taws xob nqi, kub thiab lwm yam cuam tshuam tus nqi.Tom qab lub optimizer tau nruab, lub zog tsim hluav taws xob ntawm qhov chaw nres tsheb fais fab yog 105.93% siab dua qhov ntawd nyob rau lub sijhawm uas tsis tau teeb tsa, qhov nruab nrab lub zog tsim hluav taws xob ib txoj hlua ib hnub tau nce los ntawm 7.32 KWH, thiab lub zog tsim hluav taws xob ntawm plaub txoj hlua yog nce los ntawm 29.28 KWH ib hnub.
Vim qhov txo qis ntawm cov chaw nres tsheb loj loj thiab qhov nyuaj ntawm cov peev txheej thiab ib puag ncig xws li roob, nws raug nquahu kom cov neeg coob coob siv lub ru tsev rau kev teeb tsa ntawm photovoltaic system.Peb yuav muab cov txheej txheem kev teeb tsa ua tiav thiab cov txheej txheem tom ntej hnub ci vaj huam sib luag tu.Peb yuav ib txwm cog lus los muab cov neeg siv nrog kev nyab xeeb, ruaj khov thiab txhim khu kev qha photovoltaic zog.
