Efficiency ntawm hnub ci inverter

Kev ua haujlwm ntawm hnub ci inverters txhais tau hais tias kev lag luam rau hnub ci inverters (photoelectric inverters) yog qhov loj hlob vim qhov kev thov rau lub zog tauj dua tshiab. Cov inverter no xav tau kev ua haujlwm siab thiab kev ntseeg siab. Cov hluav taws xob hluav taws xob siv hauv cov tshuab hluav taws xob no tau tshawb xyuas, thiab kev xaiv zoo tshaj plaws rau kev hloov thiab cov khoom siv rectifier tau pom zoo. Cov qauv dav dav ntawm photoelectric inverter yog qhia hauv daim duab 1, thiab peb qhov sib txawv inverters muaj rau xaiv. Lub hnub ci ci rau ntawm lub hnub ci modules txuas nrog hauv series, thiab txhua lub module muaj ib pab pawg ntawm cov hnub ci cell hauv series. Lub DC voltage generated los ntawm lub hnub ci module yog nyob rau hauv qhov kev txiav txim ntawm ob peb puas volts. Tus nqi tshwj xeeb yog nyob ntawm cov teeb pom kev zoo ntawm lub module array, qhov kub thiab txias ntawm lub roj teeb thiab tus naj npawb ntawm cov modules hauv series.

Lub luag haujlwm tseem ceeb ntawm hom inverter no yog hloov cov input DC voltage rau hauv tus nqi ruaj khov. Qhov no muaj nuj nqi yog pom tau los ntawm ib tug boost converter, uas yuav tsum tau ib tug boost hloov thiab ib tug boost diode. Nyob rau hauv thawj cov qauv, lub boost theem yog ua raws li ib tug cais tag nrho tus choj converter. Lub luag haujlwm ntawm tag nrho tus choj transformer yog muab kev sib cais. Qhov thib ob puv choj converter ntawm cov zis yog siv los hloov DC ntawm thawj theem tag nrho tus choj converter rau AC voltage. Nws cov zis tau lim ua ntej txuas nrog AC lub zog hluav taws xob los ntawm kev sib txuas ntxiv ob npaug ntawm kev sib txuas, txhawm rau muab kev sib cais kom muaj kev nyab xeeb thaum muaj xwm txheej txhaum cai thiab kev cais tawm ntawm daim phiaj hluav taws xob hmo ntuj. Tus qauv thib ob yog cov txheej txheem tsis nyob ib leeg. Ntawm lawv, AC voltage yog ncaj qha tsim los ntawm DC voltage tso tawm los ntawm theem voltage nce. Tus qauv thib peb siv lub thev naus laus zis thev naus laus zis ntawm lub zog hloov pauv thiab lub zog diode los ua ke cov haujlwm ntawm kev txhawb nqa thiab AC tiam nyob rau hauv ib qho kev mob siab rau topology. Txawm hais tias kev hloov dua siab tshiab ntawm lub hnub ci vaj huam sib luag yog tsawg heev, nws yog ib qho tseem ceeb heev uas yuav tsum ua kom lub zog ntawm lub inverter ze li ntawm 100 feem pua. Nyob rau hauv lub teb chaws Yelemees, 3kW series module tau nruab rau ntawm lub ru tsev uas tig mus rau sab qab teb xav tias yuav tsim tau 2550 kWh ib xyoos twg. Yog hais tias lub inverter efficiency nce ntawm 95 feem pua ​​​​rau 96 feem pua, nws tuaj yeem tsim tau ntau dua 25kWh txhua xyoo. Tus nqi ntawm kev siv cov hnub ci ntxiv los tsim qhov 25kWh yog sib npaug rau kev ntxiv ib qho inverter. Txij li qhov nce hauv kev ua tau zoo los ntawm 95 feem pua ​​​​rau 96 feem pua ​​​​yuav tsis ua ob npaug ntawm tus nqi ntawm lub inverter, nws yog ib qho inevitable los nqis peev hauv ntau cov inverters. Rau kev tsim tawm tshiab, cov qauv tsim qauv tseem ceeb yog txhawm rau txhim kho lub inverter efficiency tshaj tus nqi zoo. Qhov kev ntseeg tau thiab tus nqi ntawm inverter yog lwm yam kev tsim qauv. Kev ua haujlwm siab dua tuaj yeem txo qhov kub ntawm qhov hloov pauv ntawm lub voj voog thauj khoom, yog li txhim kho kev ntseeg tau. Yog li ntawd, cov qauv no yeej muaj feem cuam tshuam. Kev siv cov modules kuj yuav txhim kho kev ntseeg tau.
