1.1 Uhlolojikelele lomkhiqizo kanye nezici
Uchungechunge lwe-HH luwumshini omusha ohlanganisiwe wokulawula amandla elanga ohlanganisa isitoreji samandla elanga ohlanganisa isitoreji samandla elanga kanye nesitoreji samandla sokushaja amapayipi kanye nokuphuma kwe-AC sine wave.Yamukela ukulawulwa kwe-DSP kanye ne-algorithm yokulawula ethuthukisiwe, enesivinini esikhulu sokuphendula nokuthembeka okuphezulu.kanye namazinga aphezulu ezimboni.Kunezinhlobo ezine zokushaja ozikhethela izindlela: i-solar kuphela, okubalulekile kwamapayipi amakhulu, ukubaluleka kwamandla elanga kanye namapayipi amakhulu kanye nelanga;izindlela ezimbili zokuphuma ze-inverter kanye nama-mayins azikhethela ukuhlangabezana nezidingo ezahlukene zohlelo lokusebenza.
Imodyuli yokushaja yelanga ithatha ubuchwepheshe bamuva bokulandelela be-MPPT obulungiselelwe, obungakwazi ukulandelela ngokushesha indawo yamandla ephezulu ye-photovoltaic array kunoma iyiphi indawo, futhi ithole amandla amaningi wephaneli yelanga ngesikhathi sangempela.
Imojula yokushaja ye-AC-DC isebenzisa i-algorithm yokulawula ethuthukisiwe ukuze ikwazi ukusebenzisa amandla kagesi edijithali ngokugcwele nokulawula kwamanje okuphindwe kabili kweluphu evaliwe, ngokunemba kokulawula okuphezulu nosayizi omncane.Ibanga le-AC voltage input libanzi, imisebenzi yokuvikela okokufaka/yokukhiphayo iphelele, futhi ibhethri lingashajwa futhi livikelwe ngokuzinzile nangokuthembekile.
Imojula ye-DC-AC inverter isuselwe ekwakhiweni kobuhlakani obuyidijithali yonke, yamukela ubuchwepheshe obuthuthukisiwe be-SPWM, ikhipha i-sine wave ehlanzekile, iguqula imanje eqondile ibe yamanje eshintshashintshayo, futhi ifanele imithwalo ye-AC efana nemishini yasendlini, amathuluzi kagesi, amathuluzi asezimbonini, ngogesi. umsindo nevidiyo.Umkhiqizo wamukela umklamo wokubonisa we-LCD wengxenye, obonisa idatha yokusebenza nesimo sokusebenza sohlelo ngesikhathi sangempela.Imisebenzi ebanzi yokuvikela i-elekthronikhi iqinisekisa ukuthi lonke uhlelo luphephile futhi zizinzile.
Izici:
1. Yamukela ngokugcwele i-voltage yedijithali kanye nokulawula kwamanje okuyiluphu evaliwe ephindwe kabili, ubuchwepheshe obuthuthukisiwe be-SPWM, ukuphuma kwe-sine wave.
2. Inezindlela ezimbili zokukhiphayo ze-bypass eyinhloko kanye nokukhishwa kwe-inverter, futhi inomsebenzi wokunikezwa kwamandla okungaphazamiseki.
3. Kukhona izindlela zokushaja ezingu-4 ongakhetha kuzo: i-solar kuphela, okubalulekile ku-mains, ukubaluleka kwelanga, nokushaja okuxubile.
4. Ubuchwepheshe be-MPPT obuthuthukisiwe, ukusebenza kahle kuphezulu njengo-99.9%.
5. Idizayini ye-LCD liquid crystal screen, izinkomba ze-4 ze-LED, ukuboniswa okuguquguqukayo kwedatha yesistimu nesimo sokusebenza.6. Iswishi ye-rocker ye-ON/OFF ilawula ukuphuma kwe-AC.
7. Inomsebenzi wemodi yokonga amandla ukunciphisa ukulahlekelwa okungalayishiwe.
8. Thola ifeni yesivinini eshintshwayo ehlakaniphile, ukuchithwa kokushisa okusebenzayo kanye nokwelula impilo yesistimu.
9. Ibhethri ye-lithium enebhethri yamandla elanga kanye nomsebenzi wokuvula ama-mains, isekela ibhethri le-lead-acid, ukufinyelela kwebhethri ye-lithium.10. Ngemisebenzi eminingi yokuvikela, ukuvikela okungu-360° nxazonke.
10. Inokuvikela okuphelele kwesiyingi esifushane, isivikelo se-over-and under-voltage, isivikelo sokulayisha ngokweqile, isivikelo se-back-feed, njll.
