Hloov DC mus rau AC: Nkag siab txog thev naus laus zis thiab nws cov ntawv thov
Nyob rau hauv lub ntiaj teb niaj hnub no, muaj kev xav tau ntau ntxiv rau cov thev naus laus zis hloov pauv hluav taws xob zoo thiab txhim khu kev qha. DC mus rau AC inverter yog ib qho thev naus laus zis uas tau txais kev saib xyuas ntau. Cov thev naus laus zis ua lub luag haujlwm tseem ceeb hauv kev hloov pauv hluav taws xob ncaj qha (DC) mus rau hauv hluav taws xob hloov pauv (AC), ua rau nws haum rau ntau yam kev siv thoob plaws ntau yam lag luam.
Lub luag haujlwm tseem ceeb ntawm DC-rau-AC inverter yog hloov DC lub zog tsim los ntawm cov vaj huam sib luag hnub ci, roj teeb, lossis lwm yam DC fais fab chaw rau hauv AC fais fab, thiab feem ntau siv hauv tsev, lag luam, thiab kev lag luam. Cov txheej txheem hloov pauv no yog qhov tseem ceeb vim tias ntau yam khoom siv hluav taws xob thiab khoom siv khiav ntawm AC fais fab, yog li lub inverter ua haujlwm ua tus choj ntawm DC fais fab chaw thiab AC load.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv DC mus rau AC inverter yog lub peev xwm los muab lub zog txhim khu kev qha thiab ruaj khov. Qhov no tseem ceeb heev rau cov chaw tsis muaj hluav taws xob lossis thaj chaw deb uas tsis muaj kev nkag mus rau lub grid tseem ceeb. Hauv qhov no, cov inverters ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev muab hluav taws xob AC tas mus li rau ntau yam kev siv suav nrog teeb pom kev zoo, cua sov, txias thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob.
Tsis tas li ntawd xwb, kev siv cov inverters hauv cov tshuab hluav taws xob rov ua dua tshiab xws li kev teeb tsa hluav taws xob hnub ci tab tom nrov zuj zus. Cov vaj huam sib luag hnub ci tsim cov hluav taws xob ncaj qha, uas yuav tsum tau hloov mus rau hluav taws xob hloov pauv kom sib xws nrog lub grid lossis los muab hluav taws xob rau cov khoom siv hauv tsev. Cov inverters tsim tshwj xeeb rau kev siv hnub ci muaj cov yam ntxwv siab heev xws li Maximum Power Point Tracking (MPPT) los ua kom zoo tshaj plaws cov hluav taws xob ntawm cov vaj huam sib luag hnub ci, yog li ua kom lub kaw lus ua haujlwm tau zoo tshaj plaws.
Ntxiv rau kev tsim hluav taws xob los ntawm lub hnub ci, cov inverters kuj tseem siv dav hauv cov tshuab khaws cia hluav taws xob uas siv roj teeb. Cov tshuab no khaws cov zog rov ua dua tshiab lossis cov zog ntau dhau uas tsim tawm thaum lub sijhawm tsis yog lub sijhawm siab tshaj plaws thiab pub rov qab rau lub grid lossis muab hluav taws xob rau cov khoom siv tseem ceeb thaum lub sijhawm tsis muaj hluav taws xob. Cov inverters ua lub luag haujlwm tseem ceeb hauv kev tswj hwm kev them roj teeb thiab kev tso tawm thaum ua kom muaj kev hloov pauv ntawm DC thiab AC fais fab.
Kev nce qib hauv thev naus laus zis inverter tau ua rau muaj kev tsim cov inverters me me thiab ua haujlwm tau zoo uas muaj kev ua haujlwm zoo dua thiab kev ntseeg siab. Cov inverters niaj hnub no muaj cov txheej txheem tswj hwm siab heev, cov yam ntxwv tiv thaiv thiab cov kev sib txuas lus sib txuas lus, ua rau lawv haum rau ntau yam kev siv, suav nrog thaj chaw nyob, kev lag luam thiab kev lag luam.
Tsis tas li ntawd xwb, qhov kev siv zog ua haujlwm tau zoo thiab kev ruaj khov zuj zus ua rau muaj kev xav tau cov inverters zoo los txo qhov kev poob hluav taws xob thiab siv zog rov ua dua tshiab tau zoo tshaj plaws. Yog li ntawd, cov chaw tsim khoom txuas ntxiv tsim kho tshiab thiab tsim cov kev daws teeb meem inverter kom tau raws li qhov xav tau ntawm kev ua lag luam thaum ua raws li cov qauv zoo thiab kev nyab xeeb.
Xaus lus, thev naus laus zis inverter DC mus rau AC ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev sib koom ua ke ntawm lub zog rov ua dua tshiab, cov txheej txheem khaws cia lub zog thiab cov kev daws teeb meem hluav taws xob tawm ntawm lub network. Nws qhov kev hloov pauv tau yooj yim thiab kev ntseeg tau ua rau nws yog ib feem tseem ceeb ntawm cov txheej txheem hluav taws xob niaj hnub, pab txhawb rau kev txhim kho ntawm cov khoom siv hluav taws xob ruaj khov thiab muaj zog. Raws li qhov kev thov rau cov kev daws teeb meem hluav taws xob huv txuas ntxiv mus, lub luag haujlwm ntawm inverters hauv kev pab txhawb kev hloov pauv thiab kev siv hluav taws xob DC thiab AC yuav tsuas yog pom tseeb dua hauv xyoo tom ntej.
