Dab tsi ntawm Grid Inverters?

On-grid inverters, tseem hu ua grid-tied inverters, yog cov khoom siv hluav taws xob uas hloov hluav taws xob ncaj qha (DC) tsim los ntawm cov khoom siv hluav taws xob tauj dua tshiab, xws li hnub ci vaj huam sib luag lossis cua turbines, mus rau hauv alternating tam sim no (AC) uas tau sib xws nrog daim phiaj siv hluav taws xob. .

Cov haujlwm tseem ceeb ntawm On-grid Inverters

Maximum Power Point Tracking (MPPT):Lawv optimize lub zog rho tawm los ntawm lub hnub ci vaj huam sib luag los ntawm kev taug qab qhov siab tshaj plaws lub zog taw tes nyob rau hauv ntau yam kev mob.

Kev hloov pauv AC:Lawv hloov lub zog DC uas tsim los ntawm cov hnub ci vaj huam sib luag rau hauv AC lub zog ntawm qhov hluav taws xob thiab zaus yuav tsum tau rau hauv daim phiaj hauv zos.

Grid Integration:Lawv synchronize lub generated AC fais fab mov nrog rau cov hluav taws xob daim phiaj, sib piv voltage theem, zaus, thiab theem.

Kev nyab xeeb nta:Lawv suav nrog kev tiv thaiv kev tiv thaiv, uas cuam tshuam cov kab ke ntawm kab sib chaws thaum muaj hluav taws xob tsis zoo, tiv thaiv lub inverter los ntawm kev xa hluav taws xob rov qab mus rau cov kab thaum cov neeg ua haujlwm siv hluav taws xob tuaj yeem tshwm sim.

Kev soj ntsuam thiab kev sib txuas lus:Niaj hnub nimno on-grid inverters feem ntau suav nrog kev saib xyuas kev muaj peev xwm, tso cai rau cov tswv tsev thiab cov neeg ua haujlwm tswj xyuas kev ua haujlwm ntawm lawv lub hnub ci nyob deb.

Net Metering Compatibility:On-grid inverters txhawb nqa net metering, uas tso cai rau kev tsim hluav taws xob ntau dhau los ua kom rov qab mus rau tus neeg siv khoom siv nyiaj, txo lawv cov nqi hluav taws xob zoo.

Yuav ua li cas yog ib tug on-grid inverter ua hauj lwm?

DC nkag:Lub inverter tau txais DC lub zog los ntawm lub hnub ci vaj huam sib luag, uas feem ntau yog nyob rau theem qis voltage.

Maximum Power Point Tracking (MPPT):Txhawm rau kom ntseeg tau tias lub hnub ci vaj huam sib luag ua haujlwm ntawm lawv qhov kev ua tau zoo tshaj plaws, lub inverter siv MPPT algorithms los kho cov load ntawm cov vaj huam sib luag, nrhiav qhov chaw ua haujlwm zoo tshaj plaws uas lawv tsim hluav taws xob feem ntau muab rau huab cua tam sim no.

Hloov ua lwm yam DC rau AC:Nyob rau hauv lub inverter, lub hwj chim hluav taws xob converter, feem ntau muaj xws li transistors los yog keyboards ua nyob rau hauv high zaus, hloov DC hluav taws xob rau hauv AC hluav taws xob. Qhov no yog ua tiav los ntawm cov txheej txheem hu ua inversion, uas cuam tshuam nrog kev hloov pauv sai ntawm DC voltage los tsim ib qho kev hloov pauv tam sim no.

Grid Synchronization:Lub inverter synchronizes lub AC hluav taws xob nws generates nrog cov nqi hluav taws xob, sib piv cov voltage, zaus, thiab theem. Qhov no ua kom ntseeg tau tias lub zog tsim tawm tuaj yeem muaj kev nyab xeeb thiab ua haujlwm zoo nrog daim phiaj.

Kev nyab xeeb thiab daim phiaj ua raws li:Lub inverter suav nrog cov txheej txheem kev nyab xeeb, xws li kev tiv thaiv kev tiv thaiv kev tiv thaiv, kom tshem tawm cov kab ke ntawm kab hluav taws xob yog tias nws pom lub zog hluav taws xob lossis yog tias daim phiaj tsis ua haujlwm. Qhov no tiv thaiv lub inverter los ntawm kev txuas ntxiv pub hluav taws xob rau hauv cov kab thaum cov neeg ua haujlwm siv hluav taws xob kho lawv.

Kev xa tawm fais fab:Thaum cov hluav taws xob AC synchronized nrog daim phiaj, nws yog siv ncaj qha los ntawm cov khoom siv hauv qhov chaw lossis muab rov qab rau hauv daim phiaj. Yog hais tias qhov chaw yuav tsum tau muaj zog ntau dua li lub hnub ci tsim, lub inverter yuav kos cov hluav taws xob ntxiv los ntawm daim phiaj kom tau raws li qhov xav tau. Yog tias muaj zog txaus, nws yuav raug xa tawm mus rau daim phiaj.

Saib xyuas thiab tswj:Feem ntau niaj hnub on-grid inverters tuaj nrog cov kev soj ntsuam xyuas uas tso cai rau cov neeg siv taug qab cov hluav taws xob tsim tawm thiab siv. Cov tshuab no feem ntau tuaj yeem nkag mus tau deb ntawm Is Taws Nem, muab cov ntaub ntawv hauv lub sijhawm thiab kev nkag siab txog kev ua haujlwm ntawm lub hnub ci PV system.

Net Metering:Nrog kev pab los ntawm ib tug bi-directional los yog net meter, lub inverter sau cov nqi hluav taws xob xa mus rau thiab tau txais los ntawm daim phiaj. Raws li kev ntsuas ntsuas ntsuas, txhua lub zog dhau los ntawm lub hnub ci tuaj yeem suav nrog cov hluav taws xob siv los ntawm kab sib chaws, uas ua rau cov nqi hluav taws xob qis dua.

Puas muaj ntau hom on-grid inverters?

Yog, muaj ntau ntau hom on-grid inverters, txhua tus tsim kom haum rau cov kev siv tshwj xeeb thiab kev teeb tsa. Cov hom tseem ceeb suav nrog.
Central Inverters:Cov no yog cov tsoos hom inverters siv nyob rau hauv loj dua hnub ci kev teeb tsa. Lawv yog cov loj, ib chav tsev uas hloov cov zis ntawm ntau lub hnub ci vaj huam sib luag rau hauv AC hluav taws xob. Central inverters yog tus nqi tsim nyog rau cov tshuab loj tab sis tej zaum yuav tsis zoo rau kev teeb tsa me me vim lawv qhov loj thiab qhov nyuaj.

Txoj hlua Inverters:Cov hlua inverters feem ntau yog siv rau cov vaj tsev nyob thiab me me ua lag luam hnub ci kev teeb tsa. Lawv tau tsim los tswj cov khoom sib xyaw ua ke ntawm ib lossis ntau txoj hlua ntawm lub hnub ci vaj huam sib luag. Txhua txoj hlua tuaj yeem muaj ntau lub vaj huam sib luag txuas nrog hauv series. Txoj hlua inverters muab kev yooj yim dua piv rau hauv nruab nrab inverters, vim tias lawv tuaj yeem tswj cov kev taw qhia sib txawv thiab cov kaum sab xis ntawm cov hnub ci vaj huam sib luag zoo dua.

Microinverters:Microinverters yog me me inverters ntsia ntawm tus kheej lub hnub ci vaj huam sib luag. Txhua lub vaj huam sib luag muaj nws tus kheej microinverter, uas hloov DC rau AC hluav taws xob txoj cai ntawm lub vaj huam sib luag qhov chaw.
