Isiteshi samandla elanga

Uhlelo lokuphehla amandla elanga ikakhulukazi luhlanganisa: izingxenye zamaseli elanga, izilawuli, amabhethri, ama-inverters, imithwalo, njll. Phakathi kwazo, izingxenye zamaseli elanga namabhethri yisistimu yokuphakelwa kwamandla, isilawuli kanye ne-inverter yisistimu yokulawula nokuvikela, futhi umthwalo uyitheminali yesistimu.

1. Imojula yeseli yelanga

I-solar cell module iyingxenye eyinhloko yesistimu yokuphehla amandla.Umsebenzi wayo ukuguqula ngokuqondile amandla akhazimulayo elanga abe awamanje aqondile, asetshenziswa umthwalo noma agcinwe ebhethrini ukuze enze ikhophi yasenqolobaneni.Ngokuvamile, ngokwezidingo zabasebenzisi, amaphaneli elanga amaningana axhunywe ngendlela ethile ukuze enze isikwele seseli yelanga (uhlu), bese kuba abakaki abafanelekile namabhokisi okuhlangana kwengezwa ukuze enze imojula yeseli yelanga.

2. Isilawuli sokushaja

Ohlelweni lokuphehla amandla elanga, umsebenzi oyisisekelo wesilawuli sokushaja ukuhlinzeka ngebhethri engcono kakhulu yokushaja kanye ne-voltage, ukushaja ibhethri ngokushesha, ngokushelelayo nangempumelelo, ukunciphisa ukulahlekelwa ngesikhathi sokushaja, nokwelula impilo yesevisi yebhethri. ibhethri ngangokunokwenzeka;Vikela ibhethri ekushajweni ngokweqile nasekuchithweni ngokweqile.Isilawuli esithuthukisiwe singarekhoda ngesikhathi esisodwa futhi sibonise idatha ehlukahlukene ebalulekile yesistimu, njengokushaja kwamanje, i-voltage nokunye.Imisebenzi esemqoka yesilawuli imi kanje:

1) Ukuvikelwa kokushajwa ngokweqile ukugwema ukulimala kwebhethri ngenxa ye-voltage yokushaja ngokweqile.

2) Ukuvikelwa kokukhipha ngokweqile ukuze kuvinjwe ibhethri ukuthi lingonakali ngenxa yokuphuma ku-voltage ephansi kakhulu.

I-3) Umsebenzi wokuxhumanisa i-anti-reverse uvimbela ibhethri kanye nephaneli yelanga ukuthi ingakwazi ukusetshenziswa noma ibangele ingozi ngenxa yokuxhumana okuhle nokubi.

I-4) Umsebenzi wokuvikela umbani ugwema ukulimala kulo lonke uhlelo ngenxa yokushaywa kombani.

5) Isinxephezelo sezinga lokushisa ikakhulukazi sezindawo ezinomehluko omkhulu wezinga lokushisa ukuze kuqinisekiswe ukuthi ibhethri isesimweni sokushaja esingcono kakhulu.

I-6) Umsebenzi wesikhathi ulawula isikhathi sokusebenza somthwalo futhi ugwema ukuchitha amandla.

I-7) Ukuvikelwa kwe-Overcurrent Uma umthwalo mkhulu kakhulu noma ufushane-circuited, umthwalo uzonqunywa ngokuzenzakalelayo ukuze kuqinisekiswe ukusebenza okuphephile kwesistimu.

I-8) Ukuvikelwa kokushisa ngokweqile Uma izinga lokushisa lokusebenza lesistimu liphezulu kakhulu, lizoyeka ngokuzenzakalelayo ukunikeza amandla kumthwalo.Ngemuva kokuthi iphutha seliqediwe, lizoqala kabusha ngokuzenzakalelayo ukusebenza okujwayelekile.

9) Ukuhlonzwa okuzenzakalelayo kwe-voltage Kuma-voltage ahlukene okusebenza kwesistimu, ukuhlonza okuzenzakalelayo kuyadingeka, futhi azikho izilungiselelo ezengeziwe ezidingekayo.

3. Ibhethri

Umsebenzi webhethri ukugcina amandla e-DC akhishwa amaseli elanga ukuze asetshenziswe umthwalo.Kusistimu yokukhiqiza amandla e-photovoltaic, ibhethri isesimweni sokushaja okuntantayo nokuphuma.Emini, i-solar cell array ishaja ibhethri, futhi ngesikhathi esifanayo, i-square array iphinde inikeze ugesi kumthwalo.Ebusuku, ugesi olayishiwe wonke uhlinzekwa yibhethri.Ngakho-ke, kuyadingeka ukuthi ukuzikhipha ngokwakho kwebhethri kufanele kube kuncane, futhi ukusebenza kahle kokushaja kufanele kube phezulu.Ngesikhathi esifanayo, izici ezifana nenani kanye nokusebenziseka kalula kufanele kucatshangelwe.

4. Inverter

Izinto zikagesi eziningi, njengamalambu e-fluorescent, amasethi we-TV, iziqandisi, amafeni kagesi kanye nemishini eminingi yamandla, zisebenza ngokushintshana kwamandla.Ukuze izinto ezisebenza ngogesi ezinjalo zisebenze ngokujwayelekile, uhlelo lokuphehla amandla elanga ludinga ukuguqula amandla aqondile abe awamanje ashintshanayo.Idivaysi kagesi enamandla enalo msebenzi ibizwa ngokuthi i-inverter.I-inverter futhi inomsebenzi wokulawula amandla kagesi othomathikhi, ongathuthukisa ikhwalithi yokunikezwa kwamandla wesistimu yokukhiqiza amandla we-photovoltaic.
