Hom ntawm tsev neeg lub zog cia inverters
Cov khoom siv hluav taws xob nyob hauv tsev tuaj yeem muab faib ua ob txoj hauv kev: DC coupling thiab AC txuas.Nyob rau hauv lub kaw lus photovoltaic cia, ntau yam khoom xws li hnub ci vaj huam sib luag thiab PV iav, cov tswj, hnub ci inverters, roj teeb, loads (cov khoom siv hluav taws xob), thiab lwm yam khoom siv ua haujlwm ua ke.AC lossis DC coupling yog hais txog yuav ua li cas cov hnub ci vaj huam sib luag txuas nrog lub zog cia lossis roj teeb.Kev sib txuas ntawm lub hnub ci modules thiab ESS roj teeb tuaj yeem yog AC lossis DC.Thaum feem ntau cov hluav taws xob siv hluav taws xob siv hluav taws xob ncaj qha (DC), cov hnub ci hluav taws xob tsim hluav taws xob ncaj qha, thiab cov roj teeb hnub ci hauv tsev khaws cov khoom siv tam sim no, ntau yam khoom siv yuav tsum hloov tam sim no (AC) rau kev ua haujlwm.
Nyob rau hauv hybrid hnub ci zog cia qhov system, qhov ncaj qha tam sim no generated los ntawm lub hnub ci vaj huam sib luag yog muab cia rau hauv lub roj teeb pob los ntawm tus maub los.Tsis tas li ntawd, daim phiaj tseem tuaj yeem them lub roj teeb los ntawm kev hloov pauv DC-AC bidirectional.Lub zog convergence point yog ntawm DC BESS roj teeb kawg.Thaum nruab hnub, lub tshuab hluav taws xob photovoltaic thawj zaug muab cov khoom thauj (cov khoom siv hluav taws xob hauv tsev) thiab tom qab ntawd them lub roj teeb los ntawm MPPT lub hnub ci maub los.Lub zog cia qhov system txuas nrog lub xeev daim phiaj, tso cai rau lub zog ntau dhau mus rau hauv daim phiaj.Thaum tsaus ntuj, lub roj teeb tso tawm los muab lub zog rau lub nra, nrog rau qhov tsis txaus ntxiv los ntawm daim phiaj.Nws yog ib qho tsim nyog sau cia tias cov roj teeb lithium tsuas yog muab lub zog rau off-grid loads thiab tsis tuaj yeem siv rau kev sib txuas ntawm kab sib chaws thaum lub zog hluav taws xob tawm.Nyob rau hauv cov xwm txheej uas lub hwj chim load tshaj lub hwj chim PV, ob daim phiaj thiab lub hnub ci roj teeb cia qhov system muaj peev xwm muab lub hwj chim rau lub load ib txhij.Lub roj teeb ua lub luag haujlwm tseem ceeb hauv kev ntsuas lub zog ntawm lub cev vim qhov hloov pauv ntawm lub zog hluav taws xob photovoltaic thiab thauj khoom siv hluav taws xob.Tsis tas li ntawd, lub kaw lus tso cai rau cov neeg siv los teeb tsa lub sijhawm them thiab tso tawm kom tau raws li lawv qhov tshwj xeeb xav tau hluav taws xob.
Yuav ua li cas DC Coupled Zog Cia System Ua Haujlwm
Hybrid photovoltaic + lub zog cia system
Lub hnub ci hybrid inverter sib txuas rau thiab tawm ntawm daim phiaj ua haujlwm los txhim kho kev ua haujlwm ntawm kev them nyiaj.Tsis zoo li on-grid inverters, uas tau txiav tawm lub hnub ci vaj huam sib luag thaum lub zog hluav taws xob vim muaj kev nyab xeeb, hybrid inverters muab cov neeg siv lub peev xwm los siv hluav taws xob txawm tias thaum tsaus ntuj, vim lawv tuaj yeem ua haujlwm ob qho tib si tawm ntawm kab sib chaws thiab txuas nrog daim phiaj.Ib qho zoo ntawm hybrid inverters yog qhov yooj yim zog xyuas lawv muab.Cov neeg siv tau yooj yim nkag mus rau cov ntaub ntawv tseem ceeb xws li kev ua haujlwm thiab kev tsim hluav taws xob los ntawm lub vaj huam sib luag inverter lossis cov khoom siv ntse txuas nrog.Nyob rau hauv rooj plaub uas lub kaw lus suav nrog ob lub inverters, txhua tus yuav tsum tau saib xyuas nyias.DC coupling yog ua haujlwm nyob rau hauv hybrid inverters kom txo qhov poob hauv AC-DC hloov dua siab tshiab.Lub roj teeb them ua haujlwm nrog DC txuas tuaj yeem ncav cuag kwv yees li 95-99%, piv rau 90% nrog AC txuas.
Tsis tas li ntawd, hybrid inverters yog kev lag luam, compact, thiab yooj yim rau nruab.Txhim kho lub hybrid inverter tshiab nrog DC-coupled roj teeb tej zaum yuav raug nqi ntau dua li retrofitting AC-coupled roj teeb rau hauv ib qho system uas twb muaj lawm.Lub hnub ci controllers siv nyob rau hauv hybrid inverters tsis tshua kim tshaj daim phiaj-tied inverters, thaum hloov pauv hloov yog tsawg dua li cov khoom siv hluav taws xob.Lub DC coupling hnub ci inverter tseem tuaj yeem ua ke tswj thiab inverter ua haujlwm rau hauv ib lub tshuab, uas ua rau muaj kev txuag nyiaj ntxiv hauv cov cuab yeej siv thiab cov nqi teeb tsa.Tus nqi zoo ntawm DC coupling system yog tshwj xeeb tshaj yog nyob rau hauv me me thiab nruab nrab ntawm daim phiaj hluav taws xob cia.Cov qauv tsim qauv ntawm hybrid inverters tso cai rau kom yooj yim ntxiv ntawm cov khoom thiab cov tswj, nrog rau kev xaiv ntawm kev sib txuas ntxiv cov khoom siv uas pheej yig DC hnub ci maub los.Hybrid inverters kuj tseem tsim los pab txhawb kev sib koom ua ke ntawm kev khaws cia txhua lub sijhawm, ua kom yooj yim rau cov txheej txheem ntxiv cov roj teeb.Lub tshuab hluav taws xob hybrid yog tus cwj pwm los ntawm nws qhov loj me, kev siv cov roj teeb hluav taws xob siab, thiab txo qhov ntau thiab tsawg ntawm cable, uas ua rau poob qis tag nrho.
