Centralized Inverter Ntawm Hnub Ci Inverter

Centralized inverter is generally used in large photovoltaic power stations (>10kW) nyob rau hauv lub kaw lus, ntau qhov sib npaug photovoltaic series txuas nrog tib lub hauv nruab nrab inverter DC cov tswv yim, lub zog dav dav ntawm kev siv peb-theem IGBT fais fab module, kev siv cov hluav taws xob me me teb cov nyhuv transistor, thaum siv DSP hloov dua siab tshiab maub los los txhim kho qhov zoo ntawm lub zog tsim. Ua rau nws ze heev rau sine wave tam sim no. Qhov loj tshaj feature yog lub zog siab thiab tus nqi qis ntawm qhov system. Txawm li cas los xij, vim qhov sib piv thiab ib nrab shading ntawm photovoltaic series, qhov ua tau zoo thiab hluav taws xob muaj peev xwm ntawm tag nrho photovoltaic system yog tshwm sim. Nyob rau tib lub sijhawm, lub zog tsim kev ntseeg tau ntawm tag nrho cov txheej txheem photovoltaic cuam tshuam los ntawm kev ua haujlwm tsis zoo ntawm qee pawg photovoltaic unit. Qhov kev tshawb fawb tshiab tshaj plaws yog kev siv qhov chaw vector modulation tswj thiab kev txhim kho ntawm cov tshiab inverter topological kev sib txuas kom tau txais kev ua haujlwm siab nyob rau hauv ib nrab ntawm cov xwm txheej. Nyob rau hauv SolarMax (Sori Mike) centralized inverter, koj tuaj yeem txuas lub thawv photovoltaic array interface los saib xyuas txhua txoj hlua ntawm photovoltaic panels, yog tias ib qho ntawm cov hlua tsis ua haujlwm zoo, lub kaw lus yuav xa cov ntaub ntawv no mus rau cov chaw taws teeb tswj, thiab cov hlua. tuaj yeem nres los ntawm kev tswj chaw taws teeb. Yog li ntawd, nws yuav tsis txo thiab cuam tshuam rau kev ua hauj lwm thiab lub zog tso zis ntawm tag nrho cov photovoltaic system vim tsis ua hauj lwm ntawm ib tug series ntawm photovoltaic hlua.
