Nyob rau hauv kev ua haujlwm ntawm photovoltaic fais fab nroj tsuag, peb ib txwm cia siab tias yuav ua kom lub zog hloov dua siab tshiab rau hauv hluav taws xob hluav taws xob thiaj li ua kom muaj kev ua haujlwm zoo.Yog li, yuav ua li cas peb tuaj yeem ua kom lub zog tsim hluav taws xob ntau tshaj plaws ntawm photovoltaic fais fab nroj tsuag?
Niaj hnub no, cia peb tham txog qhov tseem ceeb uas cuam tshuam rau lub zog tsim hluav taws xob ntawm photovoltaic fais fab nroj tsuag - qhov siab tshaj plaws lub zog taw tes nrhiav tshuab, uas yog qhov peb feem ntau hu uaMPPT.
Qhov Maximum Power Point Tracking (MPPT) system yog lub tshuab hluav taws xob uas ua rau lub vaj huam sib luag photovoltaic tso tawm hluav taws xob ntau dua los ntawm kev kho lub xeev ua haujlwm ntawm cov khoom siv hluav taws xob.Nws tuaj yeem khaws cov khoom siv hluav taws xob ncaj qha los ntawm lub hnub ci vaj huam sib luag hauv lub roj teeb, thiab tuaj yeem daws cov kev siv hluav taws xob hauv tsev thiab kev lag luam hauv thaj chaw deb thiab cov chaw ncig xyuas uas tsis tuaj yeem them los ntawm cov phiaj xwm hluav taws xob, tsis ua rau muaj kuab paug ib puag ncig.
Lub MPPT maub los tuaj yeem ntes cov hluav taws xob tsim hluav taws xob ntawm lub hnub ci vaj huam sib luag hauv lub sijhawm tiag tiag thiab taug qab qhov hluav taws xob siab tshaj plaws thiab tus nqi tam sim no (VI) kom lub kaw lus tuaj yeem them lub roj teeb nrog lub zog siab tshaj plaws.Siv rau hauv lub hnub ci photovoltaic systems, kev sib koom ua haujlwm ntawm cov hnub ci vaj huam sib luag, cov roj teeb, thiab cov khoom thauj yog lub hlwb ntawm lub photovoltaic system.
Lub luag haujlwm ntawm MPPT
Kev ua haujlwm ntawm MPPT tuaj yeem hais tau hauv ib kab lus: lub zog tso zis ntawm lub xov tooj ntawm tes photovoltaic muaj feem xyuam rau qhov ua haujlwm voltage ntawm MPPT maub los.Tsuas yog thaum nws ua haujlwm ntawm qhov tsim nyog tshaj plaws tuaj yeem nws lub zog tso zis muaj qhov tshwj xeeb tshaj plaws.
Vim tias lub hnub ci hlwb raug cuam tshuam los ntawm lwm yam xws li lub teeb siv thiab ib puag ncig, lawv cov hluav taws xob tso zis hloov pauv, thiab lub teeb siv hluav taws xob tsim hluav taws xob ntau dua.Lub inverter nrog MPPT lub zog siab tshaj plaws taug qab yog ua kom siv tag nrho cov hnub ci hlwb thiab ua rau 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.
MPPT tswj feem ntau ua tiav los ntawm DC / DC hloov pauv hloov hluav taws xob, cov khoom siv hluav taws xob photovoltaic txuas nrog cov khoom thauj los ntawm DC / DC Circuit Court, thiab cov cuab yeej siv hluav taws xob siab tshaj plaws yog tas li.
Tshawb xyuas qhov hloov pauv tam sim no thiab qhov hluav taws xob ntawm photovoltaic array, thiab kho lub voj voog ntawm PWM tsav tsheb teeb liab ntawm DC / DC converter raws li kev hloov pauv.
Rau linear circuits, thaum lub load tsis kam yog sib npaug rau sab hauv ntawm lub hwj chim mov, lub hwj chim mov muaj lub siab tshaj plaws hwj chim tso zis.Txawm hais tias ob qho tib si photovoltaic hlwb thiab DC / DC hloov pauv hloov hluav taws xob yog qhov tsis zoo, lawv tuaj yeem suav tias yog cov kab hluav taws xob hauv lub sijhawm luv luv.Yog li ntawd, ntev npaum li qhov sib npaug ntawm kev hloov pauv ntawm DC-DC hloov hluav taws xob hloov kho kom nws ib txwm sib npaug ntawm qhov kev tiv thaiv sab hauv ntawm lub cell photovoltaic, qhov siab tshaj plaws ntawm photovoltaic cell tuaj yeem ua tiav, thiab MPPT ntawm photovoltaic cell. tuaj yeem pom tau.
Linear, txawm li cas los xij rau lub sijhawm luv luv, tuaj yeem suav hais tias yog linear circuit.Yog li ntawd, ntev npaum li qhov sib npaug ntawm qhov kev hloov pauv ntawm DC-DC hloov dua siab tshiab kom nws yeej ib txwm sib npaug ntawm photovoltaic.
Lub zog sab hauv ntawm lub roj teeb tuaj yeem paub qhov siab tshaj plaws ntawm cov khoom siv hluav taws xob photovoltaic thiab tseem paub txog MPPT ntawm photovoltaic cell.
Kev siv MPPT
Hais txog txoj haujlwm ntawm MPPT, ntau tus neeg yuav muaj lus nug: Vim tias MPPT tseem ceeb heev, vim li cas peb tsis tuaj yeem pom nws ncaj qha?
Qhov tseeb, MPPT yog kev koom ua ke rau hauv inverter.Noj cov microinverter ua piv txwv, module-theem MPPT maub los taug qab lub zog siab tshaj plaws ntawm txhua PV module ib tus zuj zus.Qhov no txhais tau hais tias txawm tias photovoltaic module tsis ua haujlwm zoo, nws yuav tsis cuam tshuam rau lub zog tsim hluav taws xob ntawm lwm cov modules.Piv txwv li, nyob rau hauv tag nrho cov photovoltaic system, yog hais tias ib tug module raug thaiv los ntawm 50% ntawm lub hnub ci, lub siab tshaj plaws lub hwj chim taw tes mus txog qhovtwg controllers ntawm lwm cov modules yuav mus txuas ntxiv tswj lawv cov feem ntau lawm efficiency.
Yog koj txaus siab rauMPPT hybrid hnub ci inverter, txais tos hu rau photovoltaic chaw tsim tshuaj paus Radiance raunyeem ntxiv.
