Yuav ua li cas cov desies pab nrog kev tswj hwm tam sim no hauv kev faib cov hluav taws xob?

1, photovoltaic system: Dual kev tiv thaiv ntawm kub chaw tiv thaiv thiab lub zog rov qab
Raws li cov tub ntxhais kawm pawg ntawm faib hluav taws xob, photovoltaic modules ntsej muag ob txoj kev sib tw tam sim no: kev kub ntxhov thiab hmo ntuj rov qab. Thaum ib qho kev sib xyaw ua ke yog qhov ua tau zoo sib xws los yog kev ua tau zoo ntawm cov roj teeb uas tsis pom zoo, ua rau lub zos kub los ntawm cov dej roj teeb uas tsis pom zoo tshaj plaws los yog ua rau muaj hluav taws kub. Raws li kev txheeb cais, photovoltaic tshuab uas tsis muaj kev nkag siab ntawm 4 xyoos piv rau cov qauv kev teeb tsa kub ua rau muaj ntau dua 5% ntawm tag nrho cov khoom siv hluav taws xob.

Lub luag haujlwm ntawm "Hluav Taws Kub" hauv Bypass Diodes:
Tus bypass Diode, los ntawm kev coj ua tsis zoo, cia li ua thaum muaj qhov chaw kub muaj tshwm sim, tso cai rau kev hla lub siab {}}} qhov chaw kub. Piv txwv li, hauv ib pob ntawm 72 roj teeb, yog tias ib qho roj teeb uas tsis tau tsim cov khoom siv tam sim no, yam tsis muaj kev cuam tshuam rau 1a, uas tsis tau muaj cov khoom pov tseg rau 1a, ua rau muaj kev pov tseg loj; Tom qab txhim kho cov bypass diode, tus dev sib raug rau cov chav ua haujlwm tsis pub dhau ntawm 0.1 vib nas this, txo lub zog sab hauv kev ua haujlwm ntawm kev ua haujlwm ntawm kev ua haujlwm ntawm 30% -40%. Cov ntaub ntawv tshawb fawb ntawm kev faib cov xov tooj fais fab hauv lub teb chaws Yelemees pom tau tias tom qab kev txhim kho cov ntoo npog qis dua los ntawm qhov nruab nrab ntawm 8% rau ib xyoos rau 2.5%.

Tus "Warkeeper" ua haujlwm ntawm kev thaiv diodes:
Thaum photovoltic modules nres generating hluav taws xob thaum hmo ntuj lossis muaj kev kub siab los ntawm lwm lub zog, yog kev thaiv kom rov qab los ntawm kev ua haujlwm, Ib qho kev thaiv cov ntaub ntawv ib qho megaohm resistance thaum thim rov qab, ua kom rov qab tiv thaiv tam sim no thiab ua kom muaj peev xwm ntws xwb. Tom qab tau txais cov kev ua tau zoo ntawm cov khoom siv hluav taws xob ua haujlwm tau nce ntxiv ntawm 20 xyoo mus rau 25 xyoo, thiab tag nrho lub neej lub neej tau nce ntxiv ntawm 18%.

Cov khoom siv thev naus laus zis txhim kho kev tiv thaiv efficiency:
Tsoos silicon -} Kev thim rov qab wiodes muaj kev sib txuas lus txog li 1000v thiab haum rau cov hluav taws xob hluav taws xob loj; Schottky diodes yog favory favored nyob rau hauv faib photovoltas vim lawv ultra - qis rau pem hauv ntej voltage poob ntawm 0.3V. Noj ib qho 10kW system ua piv txwv, siv schottky diodes yuav txo tau lub zog los ntawm 30kWh tauj ib xyoos. Ib qho ntxiv, Graphene Ueares siv xoom bandgap cov yam ntxwv kom ua tiav qib nrawm dua li cov huab dess

2, cua fais fab system: syergistic txhim kho ntawm harmonic supression thiab converter kev tiv thaiv
Raws li ib qho tseem ceeb pab faib hluav taws xob, cov tshuab cua tshuab yuav tsum tau nyob rau ob txoj kev sib tw loj hauv kev tswj hwm: kev tiv thaiv kev ua phem thiab kev tiv thaiv kev tiv thaiv. AC zog hluav taws xob tawm los ntawm cua tshuab muaj cov ntau ntawm cov muaj kev sib raug zoo. Yog hais tias txuas ncaj qha rau lub hwj huam sib tham, nws yuav ua teeb meem xws li voltage hloov pauv thiab txo qis hauv lub hwj chim; Nyob rau tib lub sijhawm, raws li lub zog hluav taws xob chav hloov pauv ntawm cov cua fais fab system, cov inverter hloov pauv (xws li igbt) yuav tsim kom rov qab rov qab thaum muab rov qab. Yog tias tsis suppressed nyob rau hauv lub sij hawm, nws yuav ua rau cov khoom siv puas thiab ua rau kev ua haujlwm tsis tiav.

Lub "lim" kev ua haujlwm ntawm diodes nyob rau hauv hangonic supression:
Hauv cov txheej txheem rectification los ntawm cov hluav taws xob cua tshuab hluav taws xob, cov ntsuas hluav taws xob sib hloov AC lub zog rau hauv DC lub zog, muab cov tswv yim ruaj khov rau cov inverters. Los ntawm kev ua kom zoo diode tsis xws li nraim voltage poob thiab rov qab lub sijhawm rov qab los, cov ntsiab lus harmonic thaum lub sij hawm yuav raug txo. Piv txwv li, siv tus choj rectifier nrog ultrasrast rov qab dodes (rov qab lub sijhawm rov qab<50ns) can reduce harmonic distortion by 15% and improve power quality compared to traditional diodes (reverse recovery time>200ns).

Qhov zoo dua ntawm "cov lus teb ceev" hauv inverter kev tiv thaiv:
Thaum hloov cov ntsiab lus ntawm inverter raug muab tua, cov Diode ua raws li kev ua ywj siab rau txoj kev ywj pheej los tiv thaiv cov thaub qab tam sim no thiab kev puas tsuaj rau cov hloov pauv. Noj cov silicon carbide (sic) diodes ua piv txwv, lawv lub sijhawm rov qab tau sai dua li 15ns), uas yog 3-10 npaug txo kev poob thiab txhim kho kev ua haujlwm poob. Tom qab txais cov sic dic diodes nyob rau hauv ib tug cua fais fab inverter, lub system Ethoviciency nce los ntawm 40%, uas pab txo qhov hnyav tag nrho cov hnyav ntawm lub tshuab.

3, Lub Zog Ntim Khoom: Cov Kev Sib Tw Siv Hluav Taws Xob Hauv Them Nyiaj Tso Tawm thiab Kev Tiv Thaiv Rov Qab
Raws li lub "lub zog tsis" ntawm cov chaw faib khoom siv hluav taws xob, kev tswj hwm kev siv hluav taws xob tam sim no yuav tsum muaj kev tiv thaiv kom sib npaug nrog kev tiv thaiv. Thaum lub sij hawm them thiab rho tawm cov txheej txheem ntawm pob roj teeb, yog tias cov xeev ntawm qee cov hlwb, ua kom muaj kev phom sij sab hauv, thiab ua rau muaj kev nyab xeeb rau kev nyab xeeb; Nyob rau tib lub sijhawm, yog tias rov qab tam sim no tsis tau cuam tshuam zoo thaum lub sib txuas nrog lub zog cia, nws yuav cuam tshuam rau cov khoom siv hluav taws xob, nws yuav cuam tshuam rau cov khoom siv hluav taws xob thiab kev ruaj khov ntawm lub hwj chim sib tshooj.

Txawj ntse kev cai lij choj ua haujlwm ntawm Diode:
Hauv kev tswj hwm roj teeb, ntsuas phoo ntsuas hluav taws xob cov hluav taws xob ntawm txhua lub roj teeb hluav taws xob ntawm lub siab {{Voltage me me cell thaum them los tiv thaiv kev hla; Kev ua cov channel ntxiv rau tsawg - voltage hlwb thaum lub sijhawm tawm los tiv thaiv kev tawm mus. Piv txwv li, tom qab tau txais cov hluav taws xob daws cov roj teeb hauv ib lub lim tiam, muaj peev xwm sib zog ntawm 20% thiab lub neej ntev tau txuas ntxiv mus 30%.

Cov "unidirectional cais" muaj nuj nqi ntawm thim rov qab tiv thaiv Diode:
Thaum lub zog cia system txuas nrog daim phiaj, thim rov qab tiv thaiv Diode tuaj yeem tiv thaiv qhov txhaum tam sim no ntawm kev ntws rov qab mus rau hauv lub zog cia; Thaum kev ua haujlwm tawm daim phiaj, nws tuaj yeem thaiv qhov cuam tshuam ntawm kev rov qab tam sim no ntawm lub roj teeb pob ntawm lub nra. Tom qab cov kev tiv thaiv rov qab donges nyob rau hauv ib tug microgrid kev hloov pauv ntawm 50%, thiab qhov tsis ua tiav tau txo los ntawm 60%.

4, microgrid: qhov pom tsis tau sib txuas ntawm ntau-}}}}}} source source source source collab collab collab collab and and and and collab collab collab collab collab collab collab collab collab collab collab collab collab collab collab collab collab collab collab and collab and and and and and and and and and and and and and and and and and and andល
Raws li cov ntawv thov kev faib tawm ntawm cov hluav taws xob faib, micrograms yuav tsum tau tswj hwm tam sim no kom ua tiav ntau {}}}}} synchronization. Hauv microgrids tseem ceeb hauv cov zis ntawm cov yam ntxwv sib txawv xws li cov photovoltaics, cua fais fab, thiab lub zog cia. Yog tias tsis ua haujlwm zoo, nws yuav ua rau muaj teeb meem xws li cov kev tsis sib haum xeeb tam sim no thiab hluav taws xob oscillations; Nyob rau tib lub sijhawm, cov synchronization ntawm microgrids nrog lub loj sib dhos yuav tsum tau ua raws li cov neeg nruj me ntsis xws li cov hluav taws xob, thiab lwm yam yuav ua rau muaj kev sib xyaw.

Kev Koom Tes ntawm "Txhim Kho Kev Txhim Kho" ntawm Synchronous Revifier Diodes:
Hauv DC {- DC converers ntawm microgrids, synchronusle rectification thev naus laus zis tuaj yeem txo kev ua kom haum los ntawm kev hloov cov tsoos nrog mosastres. Piv txwv li, tom qab tau txais cov txheej txheem buck condchronouse, kev ua tau zoo ntawm lub microgrid nce ntawm 85%, thaum txo cov tog cua sov los ntawm 30% thiab txhim kho lub system hluav taws xob ntom ntom.

Lub "synchronous kev sib koom tes" kev ua haujlwm ntawm theem tswj diodes:
Nyob rau hauv lub pob sib txuas txuas nrog microgrid, cov theem tswj hwm cov theem ntawm cov grid voltage, kev ua tiav synchronization nrog daim phiaj loj. Tom qab npaj cov theem tswj dongs nyob rau hauv ib qho phiaj xwm kev sib txuas tau nce qib 90% rau 0,5 lub sijhawm mus rau 0.1 feeb, txhim kho cov txheej txheem ruaj khov.
