Umgomo wokusebenza kwe-Photovoltaic inverter

Isimiso Sokusebenza
Umnyombo wedivayisi ye-inverter, isifunda sokushintsha inverter, esibizwa ngokuthi i-inverter circuit.Lo mjikelezo ufeza umsebenzi we-inverter ngokusebenzisa ukuqhutshwa nokuvalwa kokushintshwa kwamandla kagesi.

Izici
(1) Idinga ukusebenza kahle okuphezulu.Ngenxa yentengo ephakeme yamanje yamaseli elanga, kuyadingeka ukuzama ukuthuthukisa ukusebenza kahle kwe-inverter ukuze ukwandise ukusetshenziswa kwamaseli elanga nokuthuthukisa ukusebenza kahle kwesistimu.

(2) Isidingo sokuthembeka okuphezulu.Njengamanje, izinhlelo zesiteshi samandla kagesi ze-PV zisetshenziswa ikakhulukazi ezindaweni ezikude, iziteshi eziningi zikagesi azinamuntu futhi zilungiswa, okudinga ukuthi i-inverter ibe nesakhiwo sesifunda esinengqondo, ukuhlolwa kwengxenye eqinile, futhi kudinga ukuthi i-inverter ibe nemisebenzi ehlukahlukene yokuvikela, njenge njengalokhu: okokufaka kwe-DC polarity ukuvikela ukuguqulwa, ukuvikelwa kwe-AC okukhipha i-short-circuit, ukushisa ngokweqile, ukuvikela ukugcwala ngokweqile nokunye.

(3) Idinga ububanzi obubanzi bokujwayela i-voltage yokufaka.Njengoba i-voltage yokugcina yeseli yelanga ishintsha ngomthwalo nokuqina kokukhanya kwelanga.Ikakhulukazi lapho ibhethri iguga i-terminal voltage yayo ishintsha ebangeni elibanzi, njengebhethri engu-12V, i-terminal voltage yayo ingase ihluke phakathi kuka-10V ~ 16V, okudinga inverter ebangeni elibanzi le-voltage yokufaka ye-DC ukuze kuqinisekiswe ukusebenza okuvamile.

I-Inverter Classification

I-Centralized, String, Distributed kanye ne-Micro.

Ngokobukhulu obuhlukahlukene obunjengomzila wobuchwepheshe, inani lezigaba zokukhipha amandla kagesi we-AC, indawo yokugcina amandla noma cha, kanye nezindawo zohlelo lokusebenza ezansi nomfula, wena ama-inverter azohlukaniswa.
1. Ngokusho kwesitoreji samandla noma cha, ihlukanisweI-inverter exhunywe kugridi ye-PVkanye ne-inverter yokugcina amandla;
2. Ngokwenani lezigaba ze-voltage ye-AC ephumayo, zihlukaniswe ngama-inverter esigaba esisodwa futhiama-inverters ezigaba ezintathu;
3. Ngokuya ngokuthi isetshenziswa ohlelweni lokuphehla ugesi oluxhunywe kugridi noma ngaphandle kwegridi, ihlukaniswe yaba inverter exhunywe kugridi futhii-off-grid inverter;
5. ngokohlobo lwe-PV yokuphehla amandla esetshenziswayo, ihlukaniswe yaba inverter yamandla e-PV ephakathi nendawo kanye ne-inverter yamandla e-PV esabalalisiwe;
6. ngokusho komzila wezobuchwepheshe, ingahlukaniswa phakathi, intambo, iqoqo kanyeama-inverters amancane, futhi le ndlela yokuhlukanisa isetshenziswa kabanzi.
