Xisaabinta Qorraxda Qorraxda
Maqaalka soosocda ayaa kaa caawin doona xisaabinta ugu badnaan / ugu yar ee cutubyada xargaha taxanaha ah marka la qaabeeyo nidaamkaaga PV-ga. Cabbirka luqadu wuxuu ka kooban yahay laba qaybood, koranta, iyo cabirka hadda jira. Inta lagu guda jiro casharka siinta waxaad u baahan tahay inaad tixgeliso xadka xadka qaabeynta ee kaladuwan, oo loo baahan yahay in la tixgeliyo markii la qaddariyo injiilka tamarta qorraxda (xogta laga helo xaashiyaha xogta qoraxda). Iyo inta lagu gudajiro cabirka, wada-tafurta heerkulka waa cunsur muhiim ah.
1. Tooska ah ee Traur Panel Picess ee ECOP / ISC:
Korontada / hadda jira ee loo yaqaan 'Qorraxda' Armare-ka) waxay ku xirnaadaan heerkulka unugyada, heerkulka sare ee korantada hoose / hadalka hadda jira ayaa soo saari doona iyo viseska-qoraxda. Korontada / hadda nidaamka ayaa had iyo jeer joogi doona ugu ugu badan xaaladaha ugu qabow ee tusaalaha ah iyo tusaale ahaan, istcimaalka qorraxda ee heerkulka qorraxda ee loo baahan yahay inay ka shaqeeyaan tan. Iyagoo wata Mono iyo Poly Crystallerine Bandar Qorrax marwalba waa shaandhada% taban% / oc, sida -0.33% / oc ee qorraxda 72p-35f. Macluumaadkaan waxaa laga heli karaa xaashida xogta soosaarayaasha qoraxda ee Solar Gudil. Fadlan tixraac jaantuska 2.
2. Maya. Tirada muraayadaha qoraxda ee xarig taxane ah:
Marka godadka qoraxda ay ku jiraan xarig taxane ah (taasi waa togan oo ah hal gole ayaa ku xiran taban ka dhaca guddiga soo socda), korantada gudi kasta lagu daro si loo siiyo wadarta korantada. Sidaa darteed waxaan u baahan nahay inaan ogaano inta qashin-qubka qoraxda ee aad ku talojirto inaad silig taxanaha.
Markaad hayso dhammaan macluumaadka aad diyaar u tahay inaad gasho silsiladaha tamarta qoraxda ee soo socota iyo xisaabinta cabirka hadda jira si aad u ogaato haddii naqshada guddiga qoraxda ay ku habboonaan doonaan shuruudahaaga.
Cabbirka korantada:
1. Korantada Max Picentat = EUC * (1+ (MIN.TEMP-25) * FARSAMADA FARSAMADA (REST)
2. Tirada ugu badan ee muraayadaha qoraxda = max. korantada korantada / korantada ugu sarreysa
Qiyaasta hadda jirta:
1. Mine Panel ee hadda = ISC * (1+ (Max.Temp-25) * * *
2. Tirada ugu badan ee xargaha = ugu badnaan. Soo gali xaafada hadda / Mineel ee hadda jirta
3. Tusaale:
Chiritiba, oo ah magaalada Brazil, macmiilku wuxuu diyaar u yahay inuu rakibo hal Renac Power 5kw Saddex Part Sconce, oo ah heerka ugu yar ee magaalada waa 30v-950v, iyo korantada ugu safka badan ayaa is adkeysan kara 1000V.
Inverter iyo DACATEED:
Solar Panel Dacaashat:
A) Qiyaasta korantada
Heerkulka ugu hooseeya (meesha ku tiirsan, halkan -3 ℃), korantada-furan v oc of modules-ka ee xargaha kasta waa inaysan ka badneyn korantada soo galitaanka ugu badan ee soo-gelinta ah (1000 v):
1) Xisaabinta korantada furan ee -3 ℃:
EUT (-3 ℃) = 45.5 * (1 + (- - - - 3-25) * (- 0.33%)) = 49.7 volt
2) Xisaabinta n tirada ugu badan ee cutubyada xadhig kastaaba:
N = Max korantada galka (1000 v) /49.7 volt = 20.12 (had iyo jeer hoos u dhig)
Tirada looxyada qorraxda ee qorraxda ee xargaha qorraxda ee ku jira waa inaysan ka badneyn 20 cutub oo ka sokow, heerkulka ugu sareeya (halkaan ku tiirsan yahay, ee MPP-da waa inay ku dhexjirtaa qaybta MPP-da oo ah line-u-dhigga (160v-95V):
3) Xisaabinta korantada ugu badan ee korantada ee VMPP-ga ee 35 ℃:
Vmpp (35 ℃) = 45.5 * (1+ (35-25) * (- 0.33%)) = 44 volt
4) Xisaabinta ugu yar ee cutubyada m modules m xarig kasta:
M = min min-min-yar
Tirada looxyada qorraxda ee qorraxda ee xarig kasta waa inuu ahaadaa ugu yaraan 4 cutub.
B) cabirka hadda jira
Wareegtada gaaban ee hadda jirta ee ix ee ururinta PV-ga waa inaysan ka badneyn soo galitaanka ugu badan ee la oggol yahay ee hadda ka mid ah line-u-dhigga tamarta qorraxda:
1) Xisaabinta ugu badan ee hadda jirta 35 ℃:
ISC (35 ℃) = ((1+ (10+ (TCSC / 100)))) * ISC) = 9.22 * (35-22) * (- 0.06%) = 9.16% a
2) Xisaabinta ps Tirada ugu badan ee xargaha xargaha:
P = gelitaanka ugu badan ee hadda jira (12.5a) /9.16 a = 1.36 xargaha (had iyo jeer ku wareegsan)
Arrayka PV-ka waa inuusan ka badneyn hal xarig.
Xusuusin:
Tallaabadan looma baahna in lagu iibiyo moptt mppt leh hal xarig.
J) Gunaanad:
1. Guudyaha PV (PV array) wuxuu ka kooban yahayhal xarig, kaas oo ku xiran saddexda wejiga 5kw ee linces.
2. Xarig kasta oo ku yaal guluullada qoraxda ee ku xiran waa inay ahaadaan4-20 cutub gudahood.
Xusuusin:
Tan iyo markii korantada ugu fiican ee saddexda wejiga ee wejiga ee wejiga ah ay tahay 630V (korantada ugu fiican ee wejiga ugu fiican ee wejiga kaliya ee wejiga ah ay tahay 360V), hufnaanta shaqada ee qalinka ugu sareeya ayaa ugu sarreeya waqtigan. Marka waxaa lagu talinayaa in la xisaabiyo tirada cutubyada qoraxda iyadoo loo eegayo korantada ugu fiican ee motttt:
N = Farsamada MPPT ee ugu fiican (-3 ° C) = 756v / 49.7V = 15.21
Qolka keligiis ah ee MENSTAL EXTER FARSAMADA FARSAMADA FARSAMADA = korantada ugu fiican ee motage re 1.2 = 630 × 1.2 = 756v
Polycrystal panel codka ugu fiican ee moltt ee ugu fiican
Marka loogu talagalay Renac Saddex wejiga wejiga r3-5k-dt ee lagula taliyay soo-jeedinta qorraxda ee soo-jeedinta qorraxda waa 16 qaybood, waxayna u baahan yihiin in lagu xidho hal xarig 16x330w = 5280W = 5280W = 5280W = 5280W.
4. Gunaanad
Galitaanka 'Inverter' ee loo yaqaan 'Beeraha' Qorrax) waxay kuxirantahay heerkulka unugyada iyo istcimaalka heerkulka. Waxqabadka ugu fiican wuxuu ku saleysan yahay korantada ugu fiican ee 'MPPT' ee ugu fiican ee qalinka.
