Txoj kev txuj ci: Muaj ob txoj kev loj: DC Coupling thiab AC Coupling
Lub photovoltaic cia zoo suav nrog lub hnub ci ntsa iab, cov tswj hwm,Hnub Ci Inverters, Zog Cia Cov Roj Teeb, thauj khoom thiab lwm yam khoom siv. Muaj ob txoj hauv kev tseem ceeb: DC txuas thiab AC coupling. AC lossis DC coupling yog hais txog txoj kev lub solar vaj huam sib luag yog txuas lossis txuas nrog lub zog cia lossis roj teeb. Hom kev sib txuas ntawm lub hnub ci thiab lub roj teeb yuav yog AC lossis DC. Feem ntau cov hluav taws xob hluav taws xob siv DC, Hnub Ci Panels tsim DC, thiab roj teeb khaws cov khoom siv hluav taws xob khiav ntawm AC.
Hybrid photovoltaic + lub zog cia kaw lus, uas yog, ncaj qha tsim los ntawm cov maub los tuaj yeem khaws cov roj teeb los ntawm kev pab roj bidirectional los ntawm kev hloov kho lub dc-ac converter. Lub Zog Sau Npe yog nyob ntawm DC roj teeb kawg. Thaum nruab hnub, photovoltaic lub zog tiam thawj lub nra, thiab tom qab ntawd tsub roj teeb rau MPP tswj hwm. Lub zog cia lub zog txuas nrog daim phiaj, thiab lub zog tshaj plaws tuaj yeem txuas nrog daim phiaj; Thaum tsaus ntuj, lub roj teeb tawm rau kev muab lub nra, thiab qhov tsis muaj peev xwm yog txhawb nqa los ntawm kab sib chaws; Thaum daim phiaj yog tawm ntawm lub zog, photovoltaic cov roj teeb tsuas yog muab lub zog rau lub pob sib txuas, thiab cov kab sib txuas nrog load siv tsis tau. Thaum lub nra hnyav dua lub photovoltaic zog tiam, daim phiaj thiab photovoltaic tuaj yeem muab lub zog nyob rau tib lub sijhawm. Vim tias photovoltaic lub zog tiam thiab thauj khoom siv fais fab tsis ruaj khov, lawv cia siab rau roj teeb kom sib npaug ntawm lub zog system. Ib qho ntxiv, lub kaw lus tseem txhawb cov neeg siv los tsim lub sijhawm them thiab rho tawm kom tau raws li tus neeg siv lub zog xav tau.

Lub hybrid inverter sib xyaw ua ke tawm-sib chaws ua haujlwm txhawm rau txhim kho kev ua tau zoo. Daim phiaj-khi inverers cia li kaw lub hwj chim rau koj lub vaj huam sib luag Solar thaum lub zog tiv thaiv kev nyab xeeb. Hybrid Invererers, ntawm qhov tod tes, cia cov neeg siv kom tau tawm-sib dhos thiab cov phiaj xwm ntawm ib lub sijhawm tib lub sijhawm, yog li hluav taws xob tau siv txawm tias lub zog nruab nrab. Hybrid Inverters ho muab cov ntaub ntawv soj ntsuam lub zog xws li kev ua tau zoo thiab kev tsim hluav taws xob tau tshawb xyuas los ntawm cov khoom siv inverter lossis cov khoom siv ntse. Yog tias lub kaw lus muaj ob lub inverers, lawv yuav tsum raug saib xyuas nyias. DC coupling txo AC-DC kev hloov dua siab tshiab. Kev them nyiaj roj teeb tau yog kwv yees li ntawm 95-99%, thaum AC Coupling yog 90%.
Hybrid Inverers yog yig, kev cog lus, thiab yooj yim rau nruab. Txhim kho lub tshiab hybrid inverter nrog DC-cov roj teeb txuas ntxiv rau cov kab sib txuas, tus mauv luam tau pheej yig dua li cov txee faib khoom, thiab dc- Cov kev daws teeb meem txuas ntxiv kuj tseem tuaj yeem tsim mus rau hauv tus tswj-inverter tag nrho-hauv-ib, txuag cov khoom siv thiab cov nqi nruab. Tshwj xeeb rau cov me thiab nruab nrab-fais fab ntawm cov tshuab sib xyaw, dc-sib txuas lub tshuab yog muaj txiaj ntsig zoo. Hybrid Inverers yog meev heev, thiab nws yooj yim ntxiv cov khoom siv tshiab thiab cov controllers. Cov khoom sib ntxiv ntxiv tuaj yeem yooj yim ntxiv siv cov kev tswj hwm dC hnub ci tsawg. Thiab hybrid inverers yog tsim los ua ke cia nyob rau txhua lub sijhawm, ua kom yooj yim ntxiv rau cov pob roj teeb ntxiv. Hybrid Inverter Systems yog qhov tseeb cog, siv cov roj teeb loj, thiab muaj cov roj ntsha me me thiab tsawg dua.

Txoj kev sib txuas DC feem ntau muaj cov teeb meem hauv qab no: Ua ntej, lub system siv DC cov xaim hluav taws xob muaj teeb meem thiab kev hloov kho cov kab sib txuas tau muaj; Thib ob, ncua sijhawm hloov ntawm cov kab sib txuas ntawm cov kab sib txuas thiab tawm-kab sib tw ntev, uas yog qhov nyuaj rau cov neeg siv siv. Kev siv hluav taws xob yog neeg pluag; Thib peb, cov neeg ntse tswj lub luag haujlwm tsis yog txaus thiab kev tswj hwm tsis txaus, ua rau nws nyuaj ua kev siv microgrid muab khoom rau tag nrho. Yog li no, qee cov tuam txhab tau xaiv lub AC Coupling Technology, xws li Yuneng.
AC co coupling system ua cov khoom tsim kho kom yooj yim dua. Yuneng paub txog ob-txoj kev ntws ntawm lub zog los ntawm kev txuas ntawm AC sab thiab lub ntsuas hluav taws xob, tshem tawm cov kev xav tau mus rau lub photovoltaic DC npav, ua cov khoom tsim kom yooj yim dua; Nws paub txog kev sib xyaw ua ke los ntawm kev sib xyaw ua ke ntawm software tiag tiag tswj thiab kho vajtse tsim txhim kho millisecond-qib hloov mus; Los ntawm cov zis tswj ntawm lub zog cia inverter thiab lub tswv yim tshiab tsim ntawm lub hnab ntim khoom siv hluav taws xob tag nrho hauv kev tswj hwm ntawm lub thawv tsis siv neeg yog pom tau.
Qhov siab tshaj plaws hloov zuj zus kev ua tau zoo ntawm AC-Coupled cov khoom yog qis dua qis dua li ntawm hybrid inverters. JinLong thiab Goodwe tseem tau deplateed ac-coupled cov khoom lag luam, feem ntau yog hom phiaj kev lag luam hloov pauv. Qhov siab tshaj plaws hloov zuj zus kev ua tau zoo ntawm AC-Coupled khoom yog 94-97%, uas yog me ntsis qis dua li ntawd ntawm hybrid inverters. Qhov no feem ntau yog vim tias cov khoom siv yuav tsum tau mus rau ob qhov kev hloov pauv ua ntej lawv tuaj yeem khaws cia rau hauv lub roj teeb, uas txo cov hluav taws xob ua haujlwm.
