Uma sikhuluma ngedolobha ebusuku, izibani zomgwaqo ziyingxenye ebalulekile. Eminyakeni yamuva nje, umqondo wokuvikelwa kwemvelo eluhlaza uye wanda kakhulu phakathi komphakathi, futhi izibani zasemgwaqweni ezisebenza ngelanga ziye zakhanga abantu abaningi. Ukuze siqinisekise ukuthi lezi zibani zasemgwaqweni zingakhanyisa ngendlela enokwethenjelwa emgwaqeni ebusuku, sidinga ukucabangela imingcele embalwa ebalulekile kuhlanganise nokugeleza kwezibani zomgwaqo, amandla ephaneli ye-photovoltaic, umthamo webhethri nokuzinza kwesilawuli. Ukuklama nokucushwa kwesistimu yokukhanya komgwaqo welanga yizici ezibalulekile. Kuhlobene nokuthi umgwaqo ungakhanyiswa ngokunengqondo futhi unomphela
Kungani kufanele sinake imingcele yokukhanya komgwaqo welanga
Amaphaneli elanga ahlobene namandla okuqoqa amandla, okungukuthi, kuthatha isikhathi esingakanani ukushaja ibhethri ngokugcwele ngokukhanya kwelanga okuphumelelayo. Umthamo webhethri we-LiFePO4 kufanele uhlobane nokuthi ukukhanya komgwaqo kungashayelwa ngokuqhubekayo phakathi nokukhanya kwasebusuku. Le mingcele kanye nezingxenye zezinhlelo zokukhanyisa emigwaqweni yelanga, uma zilungiswa ngokungafanele, zizothinta ukusebenza okuvamile kwezinhlelo zokukhanyisa emgwaqweni welanga. Isibonelo, Uma iphaneli yelanga nomthamo webhethri kukuncane kakhulu, izibani zomgwaqo zingase zingakwazi ukuhlangabezana nezidingo zamandla ebusuku, njll. Ngokuphambene nalokho, ukuqonda okujulile kwale mingcele kungasiza ekudaleni umgwaqo welanga osebenza kahle, onengqondo futhi ozinzile. izinhlelo zokukhanya ezihlinzeka ngokukhanya okuthembekile kwedolobha
Bala inani lamahora wama-watt ngosuku ku-street lig
Ingqikithi yamahora we-watt amandla kagesi asetshenziswa uhlelo lokukhanyisa emgwaqweni welanga nsuku zonke, oluthinta ngokuqondile umthamo webhethri nokukhethwa kwamandla kwephaneli yelanga. Ukuze ubale ukusetshenziswa kwamandla kwansuku zonke (ingqikithi yamahora wama-watt) wesibani somgwaqo, udinga ukwazi izici ezimbili eziyinhloko: amanzi asetshenziswayo phakathi kwezikhathi ezihlukene kanye nenani lamahora okusebenza phakathi nenkathi ngayinye yesikhathi. Ifomula yokubala isamba samahora wama-watt ngosuku imi kanje: Isamba samahora wama-watt ngosuku = Ukusetshenziswa kukagesi 1 (W) × Inani lamahora okusebenza esikhathini esihlukile. Isibonelo, ukuthatha ukukhanya komgwaqo okune-wattage yokukhanya komgwaqo okungu-100W kusebenza amahora angu-12 ngosuku, ngamahora angu-5 okuqala asebenza ngamandla angu-100% namahora angu-7 okugcina asebenza ngamandla angu-50%, bese kubalwa inani eliphelele lamahora we-watt nsuku zonke. kanje: Isamba samahora we-watt nsuku zonke = 100W × amahora angu-5 + 50W × amahora angu-7 = amahora angu-850 watt (Wh). Imiphumela yokubala ingasetshenziswa ezigabeni ezilandelayo ukuze kunqunywe umthamo webhethri namandla ephaneli yelanga adingekayo ekukhanyeni komgwaqo welanga.
Ibhethri yezinhlelo zokukhanyisa emgwaqweni welanga - umthamo
Uhlobo lwebhethri olunconyiwe oluzosetshenziswa ezinhlelweni ze-solar photovoltaic amabhethri omjikelezo ojulile. Amabhethri omjikelezo ojulile adizayinelwe ukushajwa ngokushesha ngemva kokushajwa kumazinga aphansi wamandla noma ukushajwa nokushajwa ngokuqhubekayo iminyaka eminingi. Ibhethri kufanele libe likhulu ngokwanele ukuze likwazi ukugcina amandla anele ukuze likhanyise ukukhanya kwe-LED ebusuku nangezinsuku eziguqubele. Amasistimu okukhanyisa emigwaqweni yelanga ngokuvamile asebenzisa amabhethri e-lithium (LiFePO4). Inempilo ende, ukuphepha okuhle, nokuphakeme
Bala inani lamahora wama-watt asetshenziswa isibani ngosuku. Bala ukusebenza kahle kokuguqulwa kwesistimu njengo-95% Bala ukujula kokuchithwa kwebhethri. amabhethri e-lithium abalwa njengama-95% Bala inani lezinsuku zokusebenza ezizimele (okungukuthi, inani lezinsuku uhlelo oludinga ukusebenza ngaphandle kwamaphaneli e-photovoltaic ukuze kuphehle ugesi) Umthamo webhethri odingekayo (Wh) = Isamba samahora Watt (ngosuku) x Izinsuku zokuzimela / 0.95 / Ukujula kokukhishwa kwebhethri lomjikelezo ojulile
Ucwaningo lwe-E-LITE lwezinhlelo zokukhanyisa emgwaqweni welanga
Njengamanje, ikhasimende lethu lisebenzela iphrojekthi yokukhanya komgwaqo elanga. Ikhasimende lidinga ukusebenzisa izibani zasemgwaqweni zelanga ezingu-115W, ezingadingi izinzwa futhi zisebenzisa i-PWM dimming, kodwa ezidinga ukusetha ukufiphala kwesikhathi. Umsebenzi othize osuselwe enkathini umi kanje: isikhathi sokuqala siyi-100% futhi siyaqhubeka nokusebenza amahora ama-5; isikhathi sesibili singama-50% futhi siyaqhubeka nokusebenza amahora angu-7; lapho kudingeka ukukhanya kobusuku obubodwa kuphela. Isikhathi Sokukhanya kwelanga(Ukushaja.
Isimo somgwaqo singamamitha angu-8 ububanzi, nemigwaqo engamamitha angu-1.5 nhlangothi zombili. Ukuphakama kwesigxobo sokukhanya kungamamitha angu-10, ubude be-cantilever buyimitha engu-1, futhi ibanga phakathi kwesigxobo sokukhanya kanye nomgwaqo ngamamitha angu-36, okuhlangabezana nezidingo zezinga lokukhanyisa le-M2. Ngokwemiphumela yokulingisa yokukhanyisa ye-E-LITE, kuboniswa ukuthi uchungechunge lwe-115W Omni lufaneleka kakhulu.
Watt-amahora of
Ngokusekelwe ezimeni zephrojekthi, sibale ukusetshenziswa kwamandla kwangempela ngale ndlela elandelayo:
Isamba sokusetshenziswa kokukhanya komgwaqo = (115W x 5 amahora) + (57.5W x 7 amahora) = 977.5Wh/ngosuku
Amandla we
Kuye ngesimo sephrojekthi, njengoba inani lesikhathi sokusebenza elobusuku obubodwa kuphela. Sibe sesihumusha le mfuneko yamandla
umthamo webhethri, kucatshangelwa i-voltage yesistimu yethu yebhethri ngu-25.6V
Umthamo webhethri = Isamba sokukhanya komgwaqo 977.5WH×(0+1)/25.6V/95%/95%=42.3AH
Isiphetho: Umthamo webhethri ngu: 25.6V/42A
(umthamo webhethri elilodwa ngu-6AH, ngakho-ke u-42.3AH ufinyezwa ku-42AH
I-Wattage ye-
1, Umthamo omncane wokukhiqiza amandla wephaneli yebhethri ngosuku (ibhethri izoshajwa ngokugcwele ngosuku olulodwa-6hrs)
25.6x42AH=1075.2WH
2, Ubuncane bokukhiqiza amandla okwamanje wephaneli yebhethri
1075.6WH/6H=179.2W 3, Ukusebenza kahle kokuguqulwa kwesistimu 95%
179.2W/95%=188.63
Ngokusekelwe emiphumeleni, singakhetha ukufaka imojula yephaneli yelanga engu-1pc 36V/190W (99% yesici sokushaja sokuphepha esigciniwe) ukuze sihlangabezane nezidingo zamandla zephrojekthi.
