Muaj peev xwm induced degradation (PID) tau haunted lub hnub ci kev lag luam txij li nws keeb kwm.Qhov tshwm sim no tshwm sim thaum lub high-voltage DC sab ntawm ib lub hnub ci project yog ntsia ib sab ntawm lwm yam khoom siv nrog txawv voltage.Qhov tsis sib xws tuaj yeem ua rau muaj kev hloov pauv ntawm sodium, qhov twg cov hluav taws xob nyob rau hauv lub iav module khiav thiab ua kom cov module degradation.
Steven Marsh, tus thawj coj loj ntawm kev siv thev naus laus zis thiab tsim qauv ntawm Origis Energy tau hais tias "Qhov kev loj hlob loj hauv qhov no ua rau tus cwj pwm PID no, yog tias cov qauv lossis lub zog hluav taws xob tsis tsim los rau hauv ib txoj hauv kev los txo qhov no,"
Nyias-film modules muaj kev cuam tshuam ntau dua rau PID vim tias lawv cov hluav taws xob ntau dua thiab cov khoom pleev xim, tab sis crystalline silicon panels kuj muaj kev pheej hmoo. yog hais tias muaj tej yam flaws nyob rau hauv lub wafers.Tus tsim tawm Silicon Ranch tseem ceeb ua haujlwm tiv thaiv PID rau txoj hlua inverters ntawm ob hom haujlwm.
“Lawv tau ua txawv, tab sis nws yog tib lub overarchingtxhawj xeeb tias tus tsim qauv hnub ci yuav tsum muaj, uas yog cov tsis muaj zog me me no hauvhnub ci vaj huam sib luag, koj tiv thaiv nrog anti-PID nta hauv kojinverter, "hais tias Nick de Vries, SVP ntawm thev naus laus zis thiab kev tswj hwm khoom vaj khoom tsev ntawm Silicon Ranch.
Thaum cov cuab yeej siv vaj huam sib luag tshiab tawm, nws feem ntau siv qee lub sijhawm los ua kom cov khoom lag luam txo qis kev pheej hmoo ntawm PID.Cov qauv thaum ntxov ntawm iav-rau-iav bifacial modules muaj teeb meem nrog PID, tab sis cov neeg tsim khoom tau nqis los txij thaum ntawd los, Marsh tau hais.
"[PID] rov qab los ib ntus raws li cov thev naus laus zis hloov zuj zus, vim nws tshiab heev thiab nws hloov zuj zus.Nws yog ib qho kev xav tau heev uas modules yuav tsum mus dhau, "nws hais.
Central inverters yog qhov kev nyab xeeb thawj koom ruam kom tsis txhob PID.Lawv suav nrog cov transformers built-in uas tsis zoo hauv av, cais cov DC thiab AC sab ntawm lub system.
Tab sis raws li transformerless hlua inverters tau nce ntxiv rau cov haujlwm loj dua rau lawv qhov kev yooj yim O&M, nrog cov yeeb yaj kiab nyias thiab lwm yam, cov tswv haujlwm tam sim no yuav tsum xav txog kev txo qis PID.
"Muaj ob peb txoj hauv kev tseem ceeb uas koj tuaj yeem ua tiav kev sib cais galvanic, thiab transformer yog ib qho ntawm lawv.Ua qhov kev hloov pauv mus rau qhov tsis muaj qhov hloov pauv hmoov tsis zoo tsim qhov teeb meem, "Marsh hais."Lub PV array yuav xaus rau ntab, thiab feem ntau txhais tau tias yog li ntawm ib nrab ntawm cov qauv hauv tag nrho cov kab ke yuav ntsib qhov tsis zoo rau hauv av."
Ob peb txoj hauv kev tuaj yeem siv los pab zam PID hauv kev hloov pauv tsis muaj hlua inverters.Cov neeg tsim khoom tuaj yeem ntxiv qhov hloov pauv hauv av los yog hauv av cov kauj ruam-up transformer ntawm AC sab.Thiab cov tuam txhab tam sim no tau ntxiv cov khoom siv tshwj xeeb thiab software rau cov hlua inverters los tawm tsam PID.
Marsh tau hais tias muaj ob pawg ntawm PID kev txo qis hauv txoj hluainverter- active anti-PID txoj kev thiab passive PID rov qab hom.Active anti-PID hardware thiab software kev daws teeb meem coj DC sab ntawm lub kaw lus thiab txhawb nqa qhov voltage kom tag nrho cov modules saum toj no hauv av.Ntawm qhov tod tes, PID txoj kev rov qab los ua haujlwm thaum hmo ntuj kom tshem tawm PID cov khoom khaws cia thaum nruab hnub.Txawm li cas los xij, cov chaw tsim khoom nyias zaj duab xis First Solar hais tias nws cov modules teb tau zoo dua rau kev ua haujlwm tiv thaiv PID ntau dua li PID rov qab.
Ob peb txoj hlua inverter tuam ntxhab nyob rau hauv kev ua lag luam tam sim no suav nrog cov khoom siv tiv thaiv PID thiab nrog cov software los tiv thaiv kev puas tsuaj, lossis muag cov khoom siv cais los ua cov haujlwm tiv thaiv.Piv txwv li, CPS America muab CPS Zog Ntsuas Ntsuas, thaum Sungrow tsim cov khoom siv tiv thaiv PID rau hauv nws SG125HV thiab SG250HX hlua inverters.Sungrow pib muab kev tiv thaiv PID hlua inverter nyob ib ncig ntawm 2018.
Daniel Friberg, tus thawj coj ntawm cov khoom lag luam thiab engineering ntawm Sungrow tau hais tias "Muaj cov lus nug txog tus nqi degradation ntawm cov vaj huam sib luag nyob rau lub sijhawm, yog li peb tau tsim cov kev daws teeb meem,"
Yaskawa Solectria tsis ntev los no tshaj tawm qhov kev tiv thaiv PID version ntawm nws XGI 1500-250 series hlua inverter uas tau tsim los ua haujlwm nrog Thawj Hnub Ci nyias-zaj duab xis modules.
"Qhov ntawd yuav siv ob peb qhov kev hloov me me sab hauv rau lub inverter.Nws tsis yog qhov loj heev, tab sis nws xav tau qee lub sijhawm engineering thiab cov npe hloov tshiab rau cov qauv tshiab tshwj xeeb hauv cov koob no, yog li peb nyob hauv nruab nrab ntawm kev ua pov thawj tawm hauv chav kuaj, "said Miles Russell, tus thawj coj ntawm cov khoom. Kev tswj hwm ntawm Yaskawa Solectria Solar.
Ob qho tib si Solectria thiab Thawj Hnub Ci ua lawv cov khoom lag luam hauv Tebchaws Meskas, muab cov neeg tsim khoom sib koom ua ke yooj yim kom ua tiav cov ntsiab lus txhawb nqa hauv tsev nrog rau hauv IRA.Tab sis lawv tau tham txog kev txo qis PID zoo ua ntej IRA tau sau.
Alex Kamerer, tus thawj tswj haujlwm ntawm Thawj Hnub Ci tau hais tias "Peb tau pib qhov kev sib raug zoo no ob xyoos dhau los, tsuas yog lub hom phiaj ntawm cov txheej txheem thev naus laus zis kom ua tiav cov khoom lag luam uas yooj yim sib xws nrog peb cov khoom,""Peb mus rau cov kauj ruam ntxiv kom ntseeg tau tias peb muaj kev sib raug zoo nrog peb cov neeg muab kev pabcuam, uas muaj txiaj ntsig zoo rau peb cov neeg siv khoom."
Txawm hais tias ntau cov tuam txhab lag luam inverter tau pib koom nrog cov haujlwm tiv thaiv PID hauv txoj hlua inverters raws li cov thev naus laus zis tau siv ntau dua hauv cov haujlwm loj, cov kws ua haujlwm tseem qee zaum yuav tsum khawb los ntawm cov ntaub ntawv los txheeb xyuas cov khoom muaj peev xwm tiv thaiv PID, raws li Origis's Marsh.
Nws tau hais tias "Peb pom tias muaj ob peb txoj kev xaiv nyob ntawd, thiab lawv tsis tas yuav yog tus tsav tsheb loj hauv peev thawj tus nqi ntawm inverter," nws hais."Txawm li cas los xij, cov no tsis zoo li yuav tsum tau tshaj tawm ntau yam ntawm inverter nta, tej zaum vim hais tias cov ncauj lus yog heev, heev technical, los yog txawm [vim] PID nws tus kheej yog ib qho nyuaj heev los mus ntes nyob rau hauv lub teb.Yog li peb yeej pom qee qhov transformerless inverters uas tuaj tsis muaj haujlwm no. "
Tab sis kev txo qis PID yuav dhau los ua qhov tseem ceeb dua li cov tuam txhab hnub ci tam sim no muaj kev xaiv los coj cov nqi se ntau lawm (PTC) hauv IRA.Ua kom degradation hauv kev txheeb xyuas kom cov modules tsim lub zog siab tshaj plaws kom ntev li ntev tau yuav yog qhov tseem ceeb rau kev them se cov nqi se.
"Kuv xav tias muaj kev nkag siab thoob plaws hauv kev lag luam ntawm cov xwm txheej hauv PID yog tej zaum qhov yuav tsum tau nce ntxiv - kev kawm txog lub sijhawm uas koj cov modules tuaj yeem ua rau PID, nrog rau cov kev tshawb nrhiav," Marsh hais.
