Cov Inverters Ua Haujlwm Li Cas thiab Lawv Qhov Cuam Tshuam Rau Kev Ua Haujlwm Zoo ntawm Lub Hnub Ci Vaj Huam Sib Luag
Txhawm rau kom txo qhov kev vam khom rau cov roj av fossil thiab txo qhov cuam tshuam tsis zoo rau ib puag ncig, kev siv lub zog rov ua dua tshiab, tshwj xeeb tshaj yog lub zog hnub ci, tab tom nrov zuj zus. Cov vaj huam sib luag hnub ci yog ib qho tseem ceeb ntawm cov txheej txheem zog rov ua dua tshiab vim lawv muaj peev xwm hloov lub hnub ci mus ua hluav taws xob. Txawm li cas los xij, txhawm rau siv hluav taws xob los ntawm cov vaj huam sib luag hnub ci hauv kev siv txhua hnub, peb xav tau ib lub cuab yeej ntxiv hu ua inverter. Tsab xov xwm no yuav tham txog seb cov inverters ua haujlwm li cas thiab lawv cuam tshuam li cas rau kev ua haujlwm ntawm cov vaj huam sib luag hnub ci.
Lub Inverter yog dab tsi?
Lub inverter yog ib lub cuab yeej hluav taws xob uas hloov cov hluav taws xob ncaj qha (DC) uas tsim los ntawm cov vaj huam sib luag hnub ci mus rau hauv cov hluav taws xob hloov pauv (AC) uas haum rau cov khoom siv hluav taws xob hauv tsev lossis lub zog hluav taws xob. Yog tsis muaj lub inverter, cov hluav taws xob uas tsim los ntawm cov vaj huam sib luag hnub ci yuav tsis siv ncaj qha lossis faib rau lub zog hluav taws xob. Yog li ntawd, lub inverter tseem ceeb heev hauv lub zog hluav taws xob hnub ci.
Yuav ua li cas lub Inverter ua haujlwm
1. Kev Hloov Pauv Tam Sim No
Hauv lub tshuab hluav taws xob hnub ci, cov vaj huam sib luag photovoltaic (PV) tsim hluav taws xob hauv daim ntawv ntawm cov hluav taws xob ncaj qha (DC). Lub inverter siv cov hluav taws xob DC no thiab hloov nws mus rau cov hluav taws xob hloov pauv (AC) uas sib xws nrog cov qauv ntawm lub grid (feem ntau yog 120V lossis 240V AC, nyob ntawm thaj chaw nyob).
Cov txheej txheem no suav nrog ntau theem:
- Kev kho kom raug: Cov hluav taws xob DC hloov pauv tau hloov mus ua ib daim ntawv sib xws siv cov hluav taws xob hluav taws xob.
– Kev Tig Rov Qab: Siv cov khoom siv semiconductor xws li transistors lossis MOSFETs, DC tam sim no raug hloov mus rau AC nrog lub zaus tswj.
– Kev lim dej: Txhawm rau kom ntseeg tau tias lub zog tsim tau zoo, lub inverter siv ntau cov lim dej los ua kom cov AC waveform du.
2. MPPT (Qhov Chaw Tshawb Xyuas Qhov Chaw Fais Fab Siab Tshaj Plaws)
Cov inverters niaj hnub no muaj MPPT thev naus laus zis, uas tso cai rau lub kaw lus hloov kho qhov chaw ua haujlwm ntawm cov vaj huam sib luag hnub ci kom ua rau muaj zog ntau tshaj plaws. MPPT thev naus laus zis ntsuas thiab suav nrog ntau yam xws li lub teeb ci thiab kub kom ua kom muaj zog ntau tshaj plaws los ntawm cov vaj huam sib luag hnub ci.
3. Kev Teeb Tsa Zaus thiab Voltage
Tom qab hloov pauv tam sim no mus rau AC, lub inverter ua kom ntseeg tau tias qhov zaus thiab qhov hluav taws xob ntawm hluav taws xob ua raws li cov qauv ntawm lub network hluav taws xob siv, yog li cov khoom siv hauv tsev thiab cov khoom siv tuaj yeem ua haujlwm tau zoo thiab muaj kev nyab xeeb.
