Uma sikhuluma ngedolobha ebusuku, izibani zomgwaqo emgwaqweni ziyingxenye ebalulekile. Eminyakeni yamuva nje, umqondo wokuvikelwa kwemvelo okuluhlaza ubelokhu uthandwa kakhulu emphakathini, futhi izibani zomgwaqo ezisebenzisa amandla elanga ziye zadonsela ukunaka okukhulu. Ukuze siqinisekise ukuthi lezi zibani zomgwaqo zingakhanyisa umgwaqo ngokwethembeka ebusuku, sidinga ukucabangela imingcele embalwa ebalulekile okuhlanganisa amandla okukhanya kwezibani zomgwaqo, amandla ephaneli ye-photovoltaic, umthamo webhethri kanye nokuqina komlawuli. Ukwakheka kanye nokuhlelwa kohlelo lokukhanya komgwaqo welanga kuyizinto ezibalulekile. Kuhlobene nokuthi umgwaqo ungakhanyiswa ngokufanele nangokuhlala njalo.
Kungani kufanele sinake imingcele yokukhanya komgwaqo welanga
Amaphaneli elanga ahlobene nomthamo wokuqoqa amandla, okungukuthi, kuthatha isikhathi esingakanani ukushaja ibhethri ngokugcwele ngokukhanya kwelanga okusebenzayo. Umthamo webhethri le-LiFePO4 kufanele uhlobane nokuthi isibani somgwaqo singaqhutshwa njalo yini ngesikhathi sokukhanya ebusuku. Lezi zinhlaka kanye nezingxenye zezinhlelo zokukhanyisa emgwaqweni zelanga, uma zihlelwe ngendlela engafanele, zizothinta ukusebenza okuvamile kwezinhlelo zokukhanyisa emgwaqweni zelanga. Isibonelo, Uma umthamo wephaneli yelanga kanye nebhethri uncane kakhulu, izibani zomgwaqo zingase zingakwazi ukuhlangabezana nezidingo zamandla ebusuku, njll. Ngokuphambene nalokho, ukuqonda okujulile ngalezi zinhlaka kungasiza ekudaleni izinhlelo zokukhanya emgwaqweni zelanga ezisebenza kahle, ezinengqondo neziqhubekayo ezihlinzeka ngokukhanya okuthembekile kwasemadolobheni.
Bala amahora angama-watt aphelele ngosuku nge-street lig
Amahora e-watt aphelele amandla kagesi asetshenziswa uhlelo lokukhanyisa emgwaqweni welanga nsuku zonke, okuthinta ngqo amandla ebhethri kanye nokukhethwa kwamandla kwephaneli yelanga. Ukuze ubale ukusetshenziswa kwamandla kwansuku zonke (amahora e-watt aphelele) okukhanya komgwaqo, udinga ukwazi izici ezimbili eziyinhloko: amandla kagesi okufakwayo ngezikhathi ezahlukene kanye nenani lamahora okusebenza phakathi nesikhathi ngasinye. Ifomula yokubala amahora e-watt aphelele ngosuku imi kanje: Amahora e-watt aphelele ngosuku = Ukusetshenziswa kukagesi 1 (W) × Inani lamahora okusebenza esikhathini esihlukile. Isibonelo, uma sicabanga ukuthi isibani somgwaqo esinokukhanya komgwaqo okungu-100W sisebenza amahora angu-12 ngosuku, kanti amahora okuqala ama-5 asebenza ngamandla angu-100% kanti amahora okugcina angu-7 asebenza ngamandla angu-50%, khona-ke amahora e-watt aphelele ansuku zonke abalwa kanje: Amahora e-watt ansuku zonke = 100W × amahora ama-5 + 50W × amahora angu-7 = amahora angu-850 watt (Wh). Imiphumela yokubala ingasetshenziswa ezigabeni ezilandelayo ukuthola umthamo webhethri kanye namandla ephaneli yelanga adingekayo ekukhanyeni komgwaqo welanga.
Ibhethri lezinhlelo zokukhanyisa emgwaqweni zelanga - umthamo
Uhlobo lwebhethri olunconyiwe lokusetshenziswa ezinhlelweni ze-solar photovoltaic amabhethri omjikelezo ojulile. Amabhethri omjikelezo ojulile aklanyelwe ukushaja ngokushesha ngemva kokukhishwa emazingeni aphansi amandla noma ukushaja okuqhubekayo nokukhipha iminyaka eminingi. Ibhethri kufanele libe likhulu ngokwanele ukugcina amandla anele ukusebenzisa isibani sesitaladi se-LED ebusuku nasezinsukwini ezinamafu. Izinhlelo zokukhanyisa emgwaqweni welanga zivame ukusebenzisa amabhethri e-lithium (LiFePO4). Ihlala isikhathi eside, iphephile futhi iphezulu.
Bala amahora e-watt aphelele asetshenziswa yi-light fixture ngosuku. Bala ukusebenza kahle kokuguqulwa kwesistimu njengo-95% Bala ukujula kokukhishwa kwebhethri. Amabhethri e-lithium abalwa njengo-95% Bala inani lezinsuku zokusebenza ezizimele (okungukuthi, inani lezinsuku uhlelo oludingayo ukuze lusebenze ngaphandle kwamaphaneli e-photovoltaic ukukhiqiza ugesi) Umthamo webhethri odingekayo (Wh) = Amahora e-Watt aphelele (ngosuku) x Izinsuku zokuzimela / 0.95 / Ukujula kokukhishwa kwebhethri lomjikelezo ojulile
Ucwaningo lwe-E-LITE lwezinhlelo zokukhanyisa emgwaqweni zelanga
Njengamanje, ikhasimende lethu lisebenza kuphrojekthi yokukhanya komgwaqo welanga. Ikhasimende lidinga ukusebenzisa izibani zomgwaqo zelanga ezingu-115W, ezingadingi izinzwa futhi ezisebenzisa ukufiphaza kwe-PWM, kodwa ezidinga ukusetha ukufiphaza kwesikhathi. Umsebenzi othize osekelwe esikhathini umi kanje: isikhathi sokuqala singu-100% futhi siyaqhubeka nokusebenza amahora ama-5; isikhathi sesibili singu-50% futhi siyaqhubeka nokusebenza amahora ayi-7; lapho kudingeka khona ukukhanya kobusuku obubodwa kuphela. Isikhathi Sokukhanya Kwelanga (Ukushaja.
Isimo somgwaqo singamamitha angu-8 ububanzi, kanye nezindlela zabahamba ngezinyawo ezingamamitha angu-1.5 nhlangothi zombili. Ukuphakama kwesigxobo sokukhanyisa kungamamitha ayi-10, ubude besitsha sokufaka ugesi singamamitha angu-1, kanti ibanga eliphakathi kwesigxobo sokukhanyisa kanye nomngcele lingamamitha angu-36, okuhlangabezana nezidingo zezinga lokukhanya le-M2. Ngokwemiphumela yokulingisa ukukhanya ye-E-LITE, kuboniswa ukuthi uchungechunge lwe-115W Omni lufaneleka kakhulu.
Amahora ama-Watt ka
Ngokusekelwe ezimweni zephrojekthi, sibale ukusetshenziswa kwamandla kwangempela kanje:
Ukusetshenziswa kokukhanya komgwaqo okuphelele = (115W x amahora ama-5) + (57.5W x amahora ama-7) = 977.5Wh/ngosuku
Umthamo we
Kuye ngesimo sephrojekthi, njengoba inani lesikhathi sokusebenza lingobusuku obubodwa kuphela. Sibe sesihumusha lokhu okudingekayo kwamandla
umthamo webhethri, uma sibheka ukuthi i-voltage yesistimu yethu yebhethri ingu-25.6V
Umthamo webhethri = Ukusetshenziswa kwezibani zasemgwaqweni okuphelele 977.5WH×(0+1)/25.6V/95%/95%=42.3AH
Isiphetho: Umthamo webhethri ngu: 25.6V/42A
(umthamo weseli yebhethri elilodwa ngu-6AH, ngakho-ke u-42.3AH uzungezwe waba ngu-42AH
Amandla kagesi
1. Umthamo omncane kakhulu wokukhiqiza amandla wephaneli yebhethri ngosuku (ibhethri lizoshajwa ngokugcwele ngosuku olulodwa-amahora ayi-6)
25.6x42AH=1075.2WH
2, Amandla okukhiqiza amandla amancane kakhulu ephaneli yebhethri
1075.6WH/6H=179.2W 3, Ukusebenza kahle kokuguqulwa kwesistimu 95%
179.2W/95%=188.63
Ngokusekelwe emiphumeleni, singakhetha ukufaka i-1pc 36V/190W (99% yesici sokushaja sokuphepha esigciniwe) iphaneli yelanga ukuze kuhlangatshezwane nezidingo zamandla zephrojekthi.
