Imisebenzi Ehlobene Ye-PV Inverter Yethulwa

1.Umsebenzi wokulandelela indawo yamandla aphezulu (MPPT).

I-Maximum Power Point Tracking (MPPT) ubuchwepheshe obuyinhloko be-photovoltaic inverters. Njengoba amandla okukhipha imodyuli ye-photovoltaic eshintsha ngokushuba kwemisebe yelanga kanye nezinga lokushisa le-module ngokwayo, kunephuzu lokusebenza elilungile, iphuzu eliphezulu lamandla (MPP). Umsebenzi we-MPPT ukwenza imojula ye-photovoltaic ihlale isebenza eduze nendawo enkulu yamandla, ngaleyo ndlela ikhulise ukusebenza kahle kokukhiqizwa kwamandla.

Ukuze kuzuzwe i-MPPT, i-inverter ye-photovoltaic izohlala ibona izinguquko zamanje kanye ne-voltage ye-module ye-photovoltaic, futhi ilungise isimo sokusebenza se-inverter ngokusho kwalezi zinguquko. Ngokuvamile, i-MPPT ifinyelelwa ngomjikelezo wokuguqulwa kwe-DC/DC, ngokulungisa isilinganiso sesignali ye-PWM yedrayivu yesiguquli se-DC/DC, ukuze ukukhishwa kwemojula ye-photovoltaic kuhlale kugcinwa eduze nendawo yamandla aphezulu.

2.Umsebenzi wokuqapha igridi yamandla

Umsebenzi wokuqapha igridi yamandla wenza i-i-photovoltaic inverter ukuqapha isimo segridi yamandla ngesikhathi sangempela, okuhlanganisa i-voltage, imvamisa, isigaba kanye neminye imingcele, ukuqinisekisa ukuhambisana nokuzinza kwesiteshi samandla e-photovoltaic kanye negridi yamandla. Ngokuqapha kwegridi, i-inverter ingakwazi ukulungisa okukhiphayo ngesikhathi sangempela ukuze ivumelane nezinguquko kugridi futhi iqinisekise ukuthi ikhwalithi yamandla ihlangabezana nezidingo zegridi. Ngaphezu kwalokho, umsebenzi wokuqapha igridi yamandla ungasiza futhi abaphathi baqonde isimo sokusebenza segridi yamandla, bathole futhi babhekane nezinkinga ezingaba khona ngesikhathi, futhi baqinisekise ukusebenza okuzinzile kwegridi yamandla.izitshalo zamandla e-photovoltaic.

3.Umsebenzi wokuvikela amaphutha

I-inverter ye-Photovoltaic inomsebenzi ophelele wokuvikela iphutha lokubhekana nezimo ezihlukahlukene ezingavamile ezingase zenzeke ekusetshenzisweni kwangempela kwenqubo, ukuvikela i-inverter ngokwayo nezinye izingxenye zesistimu emonakalweni. Lezi zici ezingaphumeleli zifaka phakathi:

1. Okokufaka kwe-undervoltage nokuvikelwa kwe-overvoltage:Uma i-voltage yokufaka iphansi noma ingaphezulu kunohlu oluthile lwe-voltage elinganiselwe, isiguquli siqala indlela yokuvikela ukuvimbela ukulimala kwedivayisi.
2. Ukuvikelwa kwamanje:Uma amandla okusebenza edlula ingxenye ethile yamanje akaliwe, isiguquli esishintshashintshayo sinqamula isekethe ngokuzenzakalelayo ukuze sinqande amandla amaningi ukuba abangele umonakalo ocingweni.
3. Ukuvikelwa komphumela wesekethe emfushane:I-inverter inomsebenzi wokuvikela wesifunda esifushane wokuphendula ngokushesha, onganqamula isifunda ngesikhathi esifushane kakhulu ngemuva kokwenzeka kwesifunda esifushane, futhi ivikele imishini emthelela wesifunda esifushane.
4. Ukuvikelwa kokuhlehla okokufaka:Uma okokufaka kulungile futhi i-electrode engalungile ihlehliswa, isiguquli sizoqala indlela yokuvikela ukuvimbela okokusebenza ukuthi konakaliswe i-voltage ehlehlayo.
5. Ukuvikelwa kombani:I-inverter inedivayisi eyakhelwe ngaphakathi yokuvikela umbani, engavikela imishini emonakalweni wombani esimweni sezulu sombani.
6. Ukuvikela ngaphezu kwezinga lokushisa:I-inverter nayo inomsebenzi wokuvikela ukushisa okungaphezulu, lapho izinga lokushisa langaphakathi lemishini liphezulu kakhulu, lizonciphisa ngokuzenzakalelayo amandla noma liyeke ukuvimbela imishini ukuthi ingalimazi ngenxa yokushisa ngokweqile.

Le misebenzi yokuvikela amaphutha ndawonye iqinisekisa ukusebenza okuzinzile nokuphepha kweinverter yelanga . Ekusetshenzisweni okusebenzayo, umsebenzi wokuvikela amaphutha we-photovoltaic inverter ubaluleke kakhulu ukuthuthukisa ukuthembeka nokuzinza kwesiteshi samandla se-photovoltaic.
