Uyini umehluko phakathi kwe-inverter yokugcina amandla kanye ne-photovoltaic inverter?

Njengengxenye eyinhloko yei-photovoltaic power generationkanye nezinhlelo zokugcina amandla, ama-inverters adumile.Abantu abaningi babona ukuthi banegama elifanayo kanye nomkhakha ofanayo wesenzo futhi bacabanga ukuthi bawuhlobo olufanayo lomkhiqizo, kodwa akunjalo.

Isithombe ama-voltaics kanye nama-inverters okugcina amandla akuwona kuphela "ozakwethu abangcono kakhulu", kodwa futhi ayahluka ezinhlelweni zokusebenza ezifana nemisebenzi, izinga lokusebenzisa, kanye nemali engenayo.

I-inverter yokugcina amandla

Isiguquli sesitoreji samandla (i-PCS), esaziwa nangokuthi “i-inverter yokugcina amandla e-bidirectional”, siyingxenye eyinhloko eqaphela ukugeleza kwezindlela ezimbili kwamandla kagesi phakathi kwesistimu yokugcina amandla kanye negridi yamandla.Isetshenziselwa ukulawula inqubo yokushaja nokukhipha ibhethri futhi yenze ukushintsha kwe-AC ne-DC.Guqula.Ingakwazi ukunikeza amandla ngokuqondile emithwalweni ye-AC uma ingekho igridi yamandla.

1. Izimiso zokusebenza eziyisisekelo

Ngokwezimo zohlelo lokusebenza kanye nomthamo weziguquli zokugcina amandla, iziguquli zokugcina amandla zingahlukaniswa zibe iziguquli ezihlanganisiwe zesitoreji samandla e-photovoltaic, iziguquli ezincane zokugcina amandla, iziguquli zokugcina amandla aphakathi nendawo, neziguquli zokugcina amandla ezimaphakathi.idivayisi yokugeleza, njll.

I-Photovoltaic energy storage hybrid kanye neziguquli zokugcina amandla aphansi zisetshenziswa ezimweni zasekhaya nezimboni nezentengiso.Ukukhiqiza amandla e-Photovoltaic kungasetshenziswa imithwalo yasendaweni kuqala, futhi amandla angaphezu kwamandla agcinwe ebhethri.Uma kusekhona amandla engeziwe, angahlanganiswa ngokukhetha.kugridi.

Amandla aphakathi nendawo, iziguquli zokugcina amandla aphakathi nendawo zingafinyelela amandla aphezulu okukhipha futhi zisetshenziswe ezimbonini nasezentengiselwano, iziteshi zikagesi, amagridi amakhulu kagesi nezinye izimo ukuze kuzuzwe ukushefa okuphezulu, ukugcwaliswa kwesigodi, ukushefa okuphezulu / ukuguqulwa kwemvamisa neminye imisebenzi.

2. Ukudlala indima ewujuqu ochungechungeni lwezimboni

I-Electro amasistimu okugcina amandla amakhemikhali ngokuvamile ahlanganisa izingxenye ezine ezibalulekile: ibhethri, isistimu yokuphatha amandla (EMS), i-inverter yokugcina amandla (PCS), kanye nohlelo lokuphatha ibhethri (BMS).

I-inverter yokugcina amandla ingalawula inqubo yokushaja nokukhipha i-iphakethe lebhethri yokugcina amandlafuthi iguqule i-AC ibe yi-DC, edlala indima ebaluleke kakhulu ochungechungeni lwezimboni.

Enhla nomfula: izinto zokusetshenziswa zebhethri, abahlinzeki bezingxenye ze-elekthronikhi, njll.;

I-Midstream: izihlanganisi zesistimu yokugcina amandla kanye nezifaki zesistimu;

Ukuphela kwesicelo esingezansi: iziteshi zamandla omoya kanye ne-photovoltaic,izinhlelo zegridi yamandla, ezendlu/izimboni nezohwebo, abaqhubi bezokuxhumana, izikhungo zedatha nabanye abasebenzisi bokugcina.

I-inverter ye-Photovoltaic

I-Photovoltaic inverter iyi-inverter enikezelwe emkhakheni wokukhiqiza amandla we-solar photovoltaic.Umsebenzi wayo omkhulu ukuguqula amandla e-DC akhiqizwe amaseli elanga abe amandla e-AC angahlanganiswa ngokuqondile kugridi futhi alayishe ngobuchwepheshe bokuguqula amandla kagesi.

Njengedivayisi yokusebenzelana phakathi kwamaseli e-photovoltaic kanye negridi yamandla, isiguquli se-photovoltaic siguqula amandla amaseli e-photovoltaic abe amandla e-AC futhi awathumele kugridi yamandla.Idlala indima ebalulekile ohlelweni lokuphehla amandla oluxhunywe kugridi ye-photovoltaic.

Ngokugqugquzelwa kwe-BIPV, ukuze kwandiswe ukusebenza kahle kokuguqulwa kwamandla elanga ngenkathi kucatshangelwa ukubukeka okuhle kwesakhiwo, izidingo zokwakheka kwe-inverter ziyahlukahluka kancane kancane.Njengamanje, izindlela ezijwayelekile ze-solar inverter yilezi: i-inverter emaphakathi, i-string inverter, i-multi-string inverter kanye ne-component inverter (i-micro-inverter).

Ukufana Nomehluko phakathi kwama-Inverters Okukhanya/Isitoreji

"Uzakwethu ongcono kakhulu": Ama-inverters e-Photovoltaic angakwazi ukukhiqiza ugesi kuphela emini, futhi amandla akhiqizwayo athinteka yisimo sezulu futhi anokungaqiniseki nezinye izinkinga.

Isiguquli sesitoreji samandla singaxazulula ngokuphelele lobu bunzima.Uma umthwalo uphansi, amandla kagesi aphumayo agcinwa ebhethrini.Lapho umthwalo uphakeme, amandla kagesi agciniwe ayakhululwa ukuze kuncishiswe ingcindezi kugridi yamandla.Uma igridi yamandla ihluleka, ishintshela kumodi ye-off-grid ukuze iqhubeke nokunikeza amandla.

Umehluko omkhulu kakhulu: Isidingo sama-inverters ezimeni zokugcina amandla siyinkimbinkimbi kakhulu kunezimo ezixhunywe kugridi ye-photovoltaic.

Ngokungeziwe ekuguquleni i-DC iye ku-AC, futhi idinga ukuba nemisebenzi efana nokuguqula isuka ku-AC iye ku-DC kanye nokushintsha ngokushesha ngaphandle kwegridi.Ngesikhathi esifanayo, i-PCS yokugcina amandla iphinde ibe isiguquli esinezinhlangothi ezimbili esinokulawula amandla kuzo zombili izikhombisi-ndlela zokushaja nokukhipha.

Ngamanye amazwi, ama-inverters okugcina amandla anezithiyo zobuchwepheshe eziphakeme.

Eminye umehluko ibonakala kula maphuzu amathathu alandelayo:

1. Izinga lokuzisebenzisa ngokwakho ama-inverters endabuko e-photovoltaic lingama-20% kuphela, kuyilapho izinga lokuzisebenzisela iziguquli zokugcina amandla liphezulu njenge-80%;

2. Lapho amandla amakhulu ehluleka, ii-inverter exhunywe kugridi ye-photovoltaicikhubazekile, kodwa isiguquli sokugcina amandla sisengakwazi ukusebenza kahle;

3. Esimeni sokuncishiswa okuqhubekayo kwezibonelelo zokukhiqiza amandla axhunywe kugridi, imali engenayo yeziguquli zokugcinwa kwamandla iphezulu kunaleyo ye-photovoltaic inverters.
