Dab tsi yog qhov siab tshaj plaws Power Point Taug qab hauv Hnub Ci Dej Twj Inverter?

Qhov siab tshaj plaws lub zog taw tes taug qab MPPT yog hais txog tias lub inverter kho cov zis hluav taws xob ntawm photovoltaic array raws li cov yam ntxwv ntawm qhov sib txawv ambient kub thiab lub teeb siv, kom lub photovoltaic array ib txwm outputs lub siab tshaj plaws hwj chim.

MPPT ua dab tsi?

Vim muaj kev cuam tshuam ntawm lwm yam xws li kev siv lub teeb thiab ib puag ncig, cov khoom siv hluav taws xob ntawm lub hnub ci hloov pauv, thiab cov hluav taws xob tawm los ntawm lub teeb siv ntau dua.Lub inverter nrog MPPT qhov siab tshaj plaws lub zog taug qab yog ua kom siv tag nrho cov hnub ci hlwb kom lawv khiav ntawm lub zog siab tshaj plaws.Qhov ntawd yog hais tias, nyob rau hauv cov xwm txheej ntawm lub hnub ci hluav taws xob tas li, lub zog tso zis tom qab MPPT yuav siab dua li ua ntej MPPT, uas yog lub luag haujlwm ntawm MPPT.

Piv txwv li, xav tias MPPT tsis tau pib taug qab, thaum cov zis voltage ntawm cov khoom yog 500V.Tom qab ntawd, tom qab MPPT pib taug qab, nws pib kho qhov kev tiv thaiv ntawm Circuit Court los ntawm cov qauv hauv Circuit Court kom hloov cov zis hluav taws xob ntawm cov khoom thiab hloov cov zis tam sim no kom txog thaum lub zog tso zis ntau tshaj (cia hais tias nws yog 550V siab tshaj), thiab ces nws mus taug qab.Nyob rau hauv txoj kev no, uas yog hais tias, nyob rau hauv cov xwm txheej ntawm lub hnub ci hluav taws xob tas li, cov zis hluav taws xob ntawm cov khoom siv ntawm 550V cov zis voltage yuav siab dua li ntawm 500V, uas yog lub luag haujlwm ntawm MPPT.
Feem ntau hais lus, kev cuam tshuam ntawm irradiance thiab kub hloov pauv ntawm cov zis hluav taws xob feem ntau cuam tshuam ncaj qha hauv MPPT, uas yog hais, irradiance thiab kub yog qhov tseem ceeb cuam tshuam rau MPPT.

Nrog rau qhov txo qis ntawm irradiance, lub zog tso zis ntawm photovoltaic modules yuav raug txo.Nrog rau qhov nce ntawm qhov kub thiab txias, cov zis hluav taws xob ntawm photovoltaic modules yuav txo qis.

Inverter qhov siab tshaj plaws lub zog taw tes nrhiav (MPPT) yog nrhiav qhov siab tshaj plaws lub zog taw tes hauv daim duab saum toj no.Raws li tau pom los ntawm daim duab saum toj no, qhov siab tshaj plaws lub zog taw tes txo qis yuav luag proportionately li irradiance txo.

Nrog rau txoj kev loj hlob ntawm cov tshuab hluav taws xob, MPPT tam sim no tswj cov hnub ci arrays feem ntau ua tiav los ntawm DC / DC hloov hluav taws xob Circuit Court.Daim duab schematic yog qhia hauv qab no.

Lub photovoltaic cell array thiab cov load txuas nrog DC / DC Circuit Court.Qhov siab tshaj plaws lub zog nrhiav cov cuab yeej tas li pom qhov hloov pauv tam sim no thiab qhov hluav taws xob ntawm photovoltaic array, thiab kho PWM tsav tsheb teeb liab lub luag haujlwm piv ntawm DC / DC converter raws li kev hloov pauv.

Lub hnub ci dej twj tso kua misinvertertsim thiab tsim los ntawm Xi 'an Noker Electric siv MPPT thev naus laus zis, siv lub hnub ci vaj huam sib luag, kev tswj hwm qib siab, kev ua haujlwm ruaj khov thiab txhim khu kev qha, yog cov khoom pom zoo heev.
