Xa sithetha ngesixeko ebusuku, izibane zesitalato ezisendleleni ziyinxalenye ebalulekileyo. Kwiminyaka yakutshanje, ingcamango yokukhuselwa kwendalo eluhlaza iye yathandwa kakhulu luluntu, kwaye izibane zesitalato ezisebenzisa amandla elanga ziye zatsala ingqalelo enkulu. Ukuze siqinisekise ukuba ezi zibane zesitalato zinokukhanyisa indlela ngokuthembekileyo ebusuku, kufuneka siqwalasele iiparameter ezibalulekileyo eziquka amandla ombane ezibane zesitalato, amandla epaneli ye-photovoltaic, umthamo webhetri kunye nozinzo lomlawuli. Uyilo kunye noqwalaselo lwenkqubo yezibane zesitalato zelanga zizinto ezibalulekileyo. Inxulumene nokuba ingaba indlela ingakhanyiswa ngokufanelekileyo nangokusisigxina.
Kutheni sifanele sinikele ingqalelo kwiiparameter zokukhanya kwesitalato selanga
Iiphaneli zelanga zinxulumene nomthamo wokuqokelela amandla, oko kukuthi, kuthatha ixesha elingakanani ukutshaja ibhetri ngokupheleleyo ngokukhanya kwelanga okusebenzayo. Umthamo webhetri yeLiFePO4 kufuneka unxulumene nokuba isibane sesitalato sinokuqhutywa rhoqo ngexesha lokukhanyisa ebusuku. Ezi parameters kunye neenxalenye zeenkqubo zokukhanyisa izitalato zelanga, ukuba zenziwe ngendlela engafanelekanga, ziya kuchaphazela ukusebenza okuqhelekileyo kweenkqubo zokukhanyisa izitalato zelanga. Umzekelo, Ukuba umthamo wephaneli yelanga kunye nebhetri uncinci kakhulu, izibane zesitalato zisenokungakwazi ukuhlangabezana neemfuno zamandla ebusuku, njl. Ngokwahlukileyo koko, ukuqonda okunzulu kwezi parameters kunokunceda ukudala iinkqubo zokukhanya kwezitalato zelanga ezisebenzayo, ezinengqondo nezizinzileyo ezibonelela ngokukhanya okuthembekileyo kwedolophu.
Bala iiyure ezipheleleyo ze-watt ngosuku kwizibane zesitalato
Ii-watt-hours zizonke ngamandla ombane asetyenziswa sisixokelelwano sokukhanyisa izitrato zelanga yonke imihla, nto leyo echaphazela ngokuthe ngqo amandla ebhetri kunye nokukhethwa kwamandla epaneli yelanga. Ukubala ukusetyenziswa kwamandla kwemihla ngemihla (ii-watt-hours zizonke) zesibane sesitalato, kufuneka wazi izinto ezimbini eziphambili: i-wattage yesibane ngexesha lamaxesha ahlukeneyo kunye nenani leeyure zokusebenza ngexesha ngalinye. Ifomyula yokubala ii-watt-hours zizonke ngosuku yile ilandelayo: Ii-watt-hours zizonke ngosuku = Ukusetyenziswa kombane 1 (W) × Inani leeyure zokusebenza kwixesha lamaxesha ahlukeneyo. Umzekelo, ukuba isibane sesitalato esine-wattage ye-100W isibane sesitalato sisebenza iiyure ezili-12 ngosuku, iiyure zokuqala ezi-5 zisebenza ngamandla ali-100% kwaye iiyure zokugqibela ezisi-7 zisebenza ngamandla ali-50%, ke iiyure ze-watt-hours zizonke zemihla ngemihla zibalwa ngolu hlobo lulandelayo: Ii-watt-hours zizonke zemihla = 100W × iiyure ezi-5 + 50W × iiyure ezisi-7 = iiyure ezingama-850 ze-watt (Wh). Iziphumo zokubala zingasetyenziswa kula macandelo alandelayo ukuze kuchongwe umthamo webhetri kunye namandla epaneli yelanga afunekayo kwisibane sesitalato selanga.
Ibhetri yeenkqubo zezibane zesitalato zelanga - umthamo
Uhlobo lwebhetri olucetyiswayo olusetyenziswa kwiinkqubo zelanga ze-photovoltaic ziibhetri ze-deep cycle. Iibhetri ze-deep cycle zenzelwe ukutshaja ngokukhawuleza emva kokuba zikhutshiwe kumanqanaba aphantsi amandla okanye ukutshaja okuqhubekayo nokukhupha itshaja iminyaka emininzi. Ibhetri kufuneka ibe nkulu ngokwaneleyo ukugcina amandla aneleyo okusebenzisa isibane sesitalato se-LED ebusuku nakwiimini ezinamafu. Iinkqubo zezibane zesitalato zelanga zihlala zisebenzisa iibhetri ze-lithium (LiFePO4). Ihlala ixesha elide, ikhuselekile, kwaye iphezulu.
Bala iiyure ezipheleleyo ze-watt ezisetyenziswa sisibane ngosuku. Bala ukusebenza kakuhle kwenkqubo njengo-95% Bala ubunzulu bokukhutshwa kwebhetri. iibhetri ze-lithium zibalwa njengo-95% Bala inani leentsuku zokusebenza ezizimeleyo (oko kukuthi, inani leentsuku inkqubo efunekayo ukuze isebenze ngaphandle kweephaneli ze-photovoltaic ukuvelisa umbane) Umthamo webhetri ofunekayo (Wh) = Iiyure ze-Watt zizonke (ngosuku) x Iintsuku zokuzimela / 0.95 / Ubunzulu bokukhutshwa kwebhetri yomjikelo onzulu
Isifundo se-E-LITE seenkqubo zokukhanyisa izitalato zelanga
Okwangoku, umthengi wethu usebenza kwiprojekthi yezibane zesitalato zelanga. Umthengi ufuna ukusebenzisa izibane zesitalato zelanga ze-115W, ezingadingi zinzwa kwaye zisebenzisa ukufiphaza kwe-PWM, kodwa ezifuna ukuseta ukufiphaza kwexesha. Umsebenzi othile osekelwe kwixesha ngulo ulandelayo: ixesha lokuqala liyi-100% kwaye liyaqhubeka nokusebenza iiyure ezi-5; ixesha lesibini liyi-50% kwaye liyaqhubeka nokusebenza iiyure ezi-7; apho kufuneka khona ukukhanya kube kanye ebusuku. Ixesha Lokukhanya Kwelanga (Ukutshaja).
Imeko yendlela ibanzi ngeemitha ezisi-8, kunye neendlela zabahambi ngeenyawo eziziimitha ezili-1.5 kumacala omabini. Ukuphakama kwepali yokukhanya ziimitha ezili-10, ubude be-cantilever yimitha e-1, kwaye umgama phakathi kwepali yokukhanya kunye nomda wendlela ziimitha ezingama-36, nto leyo ehlangabezana neemfuno zomgangatho wokukhanya we-M2. Ngokweziphumo zokulinganisa ukukhanya ze-E-LITE, kubonisiwe ukuba uthotho lwe-115W Omni lufanelekile kakhulu.
Iiyure zeWatt ze
Ngokusekelwe kwiimeko zeprojekthi, sibale ukusetyenziswa kwamandla okwenyani ngolu hlobo lulandelayo:
Ukusetyenziswa kwezibane zesitalato iyonke = (115W x iiyure ezi-5) + (57.5W x iiyure ezi-7) = 977.5Wh/ngosuku
Umthamo we
Ngokuxhomekeke kwimeko yeprojekthi, kuba inani lexesha lokusebenza lelobusuku obunye kuphela. Emva koko siguqulela le mfuneko yamandla
umthamo webhetri, xa sicinga ukuba i-voltage yenkqubo yethu yebhetri yi-25.6V
Umthamo webhetri = Ukusetyenziswa kwezibane zesitalato zizonke 977.5WH×(0+1)/25.6V/95%/95%=42.3AH
Isiphelo: Umthamo webhetri ngu: 25.6V/42A
(umthamo weseli enye yebhetri yi-6AH, ngoko ke i-42.3AH ijikeleziswa kwi-42AH
Amandla ombane
1. Umthamo wokuvelisa umbane ophantsi kakhulu wephaneli yebhetri ngosuku (ibhetri iya kutshajwa ngokupheleleyo ngosuku olunye-iiyure ezi-6)
25.6x42AH=1075.2WH
2, Ubuncinane bokuvelisa amandla ombane wephaneli yebhetri
1075.6WH/6H=179.2W 3, Ukusebenza kakuhle kokuguqulwa kwenkqubo yi-95%
179.2W/95%=188.63
Ngokusekelwe kwiziphumo, singakhetha ukufaka i-1pc 36V/190W (99% yokhuseleko lokutshaja okugciniweyo) imodyuli yephaneli yelanga ukuhlangabezana neemfuno zamandla zeprojekthi.
