Ngakumbi ukuthi iziqephu zesitha sesolari zibe yindlela eyodwa yokugenera amandla okwesikhathi esihlwa, kuyadlula ukuzibonakalisa umsebenzi wokwenza i-solar inverter. Izinverter azisebenzi kuphela ukuguqula i-DC ku-AC, kodwa eminye iminyaka yezinverter ezinkulu nezimangalisayo ziyizinhlelo zokuhlela ukubaluleka kwezindawo zokusebenza kwamandla nokuphepha kwesiqulelo. Kuleli qephu lezinverter zase-Shenzhen Weitu Hongda Industrial Co., Ltd., sizahlola ukuthi kufanele kusukwe amandla amaningi kakhulu, futhi ukuthi amandla ayisemthethweni, ayilungile, nayikwesiqulelo. Le blog ibhabhaliswe ngokubhekana nezindlela eziphakeme ezisetyenziswa ukufika lomsebenzi omuhle wokuhlela ukubaluleka kwezindawo zokusebenza kwamandla nesiqulelo ngamanje.
Kusuka kwe-DC ku-AC: Indlela Othwala Ngayo Amaphutha Asekhaya Okuhle, Okuphakanyisiwe
Umthwalo wokugcina ngokujulile ngokukhetha isivumelwano sesiphelo sokuthwala umphutha wesikhathi esihlukene (DC), okwenzekwa emaphaneleni ethu yokuthwala amandla, kuyinto eyenza umphutha wesikhathi esihlukene (AC) esisebenzayo. Umbuzo uphakathi kakhulu ukuthi ubunikwe njani lokhu kuvuselelo. Akukho kufanele ukwenza ukuvuselelo kuphela. Umphutha we-AC kufanele kube yisignali yesinusoidi engcono, futhi kufanele kube yilapha nesikhathi sesiphelo sokuthwala umphutha sesikhathi esihlukene (grid) nokufreqwensi.
Ukuqinisa lokhu kubuyekezwa ngokupheleleyo, iz-inverter zethu zisebenza ngemicroprocessors ephambili kakhulu nezindlela zokusebenza kwamandla okupheleleyo. Ngokumenyula isiphumo, bamenyula kabusha futhi ukuthi sibuyelekeze kuzo izinkinga zokugcina umkhakha wokugcina nokufanana kwe-frequency ngaphandle kokunye okungahloniphi, okungaba yizinkinga ezinokwenzeka emashini ebandla noma emashini yasezindustri. Ngez-inverter zethu, isine wave esihlakanipha kanye nesibalasekile siyatholakala, futhi amandla angabonakala kusukela kwezulu ayabonakalisa ekhaya lami noma kumkhakha, ayisibonakaliso esihlakanipha kakhulu, esihlakanipha kanye nesibonakaliso esihlakanipha njengalesiyo sokubonakalisa kusuka kwezindlela zokubonakalisa zokuzimisa.
Ukunciphisa i-Harmonics kanye nezilingo zokuguqula kwezindawo zokubonakalisa kwezulu
Umbuzo wokukhula kwezinhlayiya (ukuguqula kwamaphakade nezinkambiso zokuphakama komkhondo) kungabikho kwenye isistimu yezinhlayiya njengezinhlayiya zokuphakama. Amaphakade ayizindlela zokuguqula zokuphakama okungabiyo okungakwazi ukubusa izinto zokusebenza, ukungasebenzi kahle nokufa kahle. Izinkambiso zokuphakama noma izinkambiso zokuphakama okungabikho kahle kungaba ngokuphakama kokuphakama kwezinhlayiya noma ukuguqula kahle kwesilinganiso sokusebenza okungakwazi ukuthi kusenziwe imisebenzi.
Ukuzimela iziproblemi ezithi, iz-inverter zikaShenzhen Weitu Hongda ziyakhiwa ngezindlela zokuphatha. Ukufiltara okusebenzisa amandla kwe-harmonic currents kwenziwa ngemifiltara yezigaba ephakeme ukuze kususeke futhi kuphumelele isiphumo esihlukile esingahlanganisi ekubhaleni kwamandla okuhlanganisa. Ngaphezu kwalokho, iz-inverter zethu zizokwamukela ukulungiswa kwevoltage ngendlela eyodwa. Zinakukhombisa loo kuhlanganisa okunakekayo noma kusistimu yasekhaya futhi zibuyeza ngomzuzu omunye ngokumenya ukuphanda kwezindawo zabo ukulungisa i-voltage. Lokhu akuyiyo kuphela ukuvikela izinto zokusebenza zakho kodwa kufaka kwezinye izinto ezinconywa kusistimu yamandla yasekhaya.
Izinkimbinkimbi Zokusebenza Kwe-Inverter Ezinconywa Ukulungisa Ukuthula Kwesistimu Yemandla Nokusebenza Kakhulu
Izinsuku zezembele ziyisinye esikhundleni sokuthi umphakathi wokusebenzisa amandla ubukhona kusobala nokuthi izinkampani zokuguqula amandla ezinsuku zezembele ziyizinkampani eziphambili ezibizwa ngokuthi zingathembeki. Lezi zinkampani zihlanganisa ukuguqula kodwa zihlanganisa izincazelo eziningi ezithembekile ezikusiza ukuthi zidlule isibonelo sokubaluleka kwesikhundla sokusebenza kanye nokuthi zihlonge izinhlelo zabo ukuba zibe nzima kakhulu.
Sikhona izisiteme zesivuthi esizimiselwe ngokwemvelo esinezinkinga zokulungisa isibalo sokusebenza (PFC) esikunciphisa ukungafaneleka kwesibalo sokusebenza ukuze sicophele amathuba okukhula kwezibalo sokusebenza futhi sibonele isibalo sokusebenza ngokuphelele kakhulu. Kuzo kufana nezinkinga zokubuyela phansi kwezibalo sokusebenza emaphakathini amancane (LVRT) nokuphendula kwezibalo sokusebenza ngezinkampani, okusiza isivuthi ukuba libe lisebenziswe futhi libonele izinsiza zokuvumela umkhulu wokusebenza ngokushesha kumaqondiso amancane, okuyisidingo esibalulekile kumaqondiso apho izindlela zokusebenza ngokwemvelo ziyasebenza kakhulu. Ngokwale ndlela yokuvumela umkhulu wokusebenza, izisivuthi zikaShenzhen Weitu Hongda zizokuguqula isistimu yesibalo sokusebenza sesolile into yomkhulu wokusebenza owodwa ngokwemvelo engavumeleki ngokushesha kodwa into yomkhulu wokusebenza owodwa ngokwemvelo othembekile, okuyisiba sokuvumela umkhulu wokusebenza ngokushesha futhi sivumela ukudala umkhulu wokusebenza owodwa ngokwemvelo owodwa ngokwemvelo okunconywa kakhulu.
Kokugcina, kungakwazi ukuthi umshini wokuqasha kwesola nguqondo lwesikhombisa se-PV esingasivumela kuphela ukuthi kusinikele amandla, kodwa futhi amandla omele ubukhulu obuhle, obulungile, nobuhle bokuphatha i-grid. Sizokunikezela umshini wokuqasha wokushintsha owenzeka ngokufanele lezi zidingo eziningi, ukuze ukuthenga kwakho kwesola kubhekwe ngokuphelele, kusebenza ngendlela efanelekile, kanye nokuthenga okuhle kwezinsuku eziningi zokuphatha kwezindawo zethu zokuphatha amandla.
