Ndichitukuko chofulumira cha kugawa photovoltaic, madenga ochulukirapo "amavala photovoltaic" ndipo amakhala gwero lobiriwira la mphamvu zamagetsi.Kupanga mphamvu kwa dongosolo la PV kumagwirizana mwachindunji ndi ndalama zoyendetsera dongosololi, momwe mungasinthire makina opangira magetsi ndi cholinga chamakampani onse.
1. Kusiyana kwa kupanga mphamvu kwa madenga okhala ndi magawo osiyanasiyana
Monga tonse tikudziwira, maonekedwe osiyanasiyana a photovoltaic modules amalandira kuwala kwa dzuwa kudzakhala kosiyana, kotero mphamvu yopangira mphamvu ya photovoltaic systems ndi photovoltaic module orientation ili ndi chiyanjano chapafupi.Malingana ndi deta, m'dera lapakati pa 35 ~ 40 ° N latitude, mwachitsanzo, kuwala komwe kumalandiridwa ndi madenga omwe ali ndi machitidwe osiyanasiyana ndi azimuth ndi osiyana: poganiza kuti mphamvu yopangira denga loyang'ana kum'mwera ndi 100, mphamvu yopangira magetsi. denga loyang'ana kum'mawa ndi kumadzulo ndi pafupifupi 80, ndipo kusiyana kwa magetsi kungakhale pafupifupi 20%.Pamene ngodya ikusintha kuchokera kumwera kupita kummawa ndi kumadzulo, mphamvu yopangira magetsi idzakhala ikucheperachepera.
Nthawi zambiri, mphamvu yapamwamba kwambiri yopangira mphamvu zamakina imatheka kumpoto kwa dziko lapansi komwe kumalowera kum'mwera komanso kupendekera kwabwino kwambiri.Komabe, mchitidwe, makamaka anagawira photovoltaic, ndi zinthu masanjidwe nyumba ndi zoletsa powonekera m'dera, ma module photovoltaic nthawi zambiri sangathe kuikidwa mu lolunjika bwino ndi bwino mapendekeke ngodya, chigawo Mipikisano lathu wakhala mmodzi wa anagawira denga photovoltaic dongosolo. mphamvu zowawa zamphamvu, kotero momwe mungapewere kutayika kwa mphamvu zamagetsi zomwe zimabweretsedwa ndi njira zambiri, zakhala vuto lina pakukula kwa mafakitale.
2. "Chotsatira chachidule cha bolodi" pamadenga amitundu yambiri
M'machitidwe amtundu wosinthira zingwe, ma module amalumikizidwa motsatizana, ndipo mphamvu zawo zopangira mphamvu zimachepetsedwa ndi "short board effect."Pamene chingwe cha ma modules chikugawidwa m'magulu angapo a denga, kuchepetsedwa kwa mphamvu ya mphamvu ya imodzi mwa ma modules kudzakhudza mphamvu yamagetsi yamtundu wonse wa ma modules, motero zimakhudza mphamvu yopangira mphamvu ya maulendo angapo a denga.
Inverter yaying'ono imagwiritsa ntchito kapangidwe kake kofananira, kokhala ndi ntchito yodziyimira payokha yamphamvu kwambiri (MPPT), yomwe imatha kuthetseratu "short board effect" ndikuwonetsetsa kuti gawo lililonse limagwira ntchito palokha komanso kupanga mphamvu sikukhudzana, poyerekeza ndi chingwe chachikhalidwe. inverter system, pansi pamikhalidwe yomweyi, imatha kupanga 5% ~ 25% mphamvu zambiri ndikuwongolera ndalama zogulira.
Ngakhale ma modules atayikidwa padenga ndi machitidwe osiyanasiyana, zotsatira za module iliyonse zikhoza kukonzedwa pafupi ndi malo okwera kwambiri, kotero kuti madenga ambiri akhoza "kuvala PV" ndikupanga mtengo wochuluka.
3. Micro-inverter mu ntchito yapadenga yamitundu yambiri
Ma Micro inverters, okhala ndi luso lapadera laukadaulo, ndi oyenera kwambiri pamapulogalamu apadenga a PV amitundu ingapo, ndipo atumikira mayiko ndi zigawo zopitilira 100, ndikupereka mayankho aukadaulo a MLPE pamlingo wa PV wapadenga lamitundu ingapo.
4. Pulojekiti ya PV yapakhomo
Posachedwapa, pulojekiti ya PV ya 22.62kW inamangidwa ku Brazil.Kumayambiriro kwa polojekitiyi, mwiniwakeyo ankayembekezera Pambuyo pa mapangidwe a polojekitiyo, ma modules a PV adayikidwa pamapeto pake pa madenga asanu ndi awiri a machitidwe osiyanasiyana, ndipo pogwiritsa ntchito mankhwala a micro-inverter, madenga anagwiritsidwa ntchito mokwanira.Mu ntchito yeniyeni ya magetsi, yomwe imakhudzidwa ndi maulendo angapo, kuchuluka kwa ma radiation a dzuwa omwe amalandiridwa ndi ma modules pa madenga osiyanasiyana amasiyana, ndipo mphamvu zawo zopangira mphamvu zimasiyana kwambiri.Tengani ma modules ozungulira mu chithunzi chomwe chili pansipa mwachitsanzo, madenga awiri omwe akuyang'ana mozungulira mofiira ndi buluu amafanana ndi kumadzulo ndi kummawa motsatira.
5. Ntchito zamalonda za PV
Kuphatikiza pa ntchito zokhalamo, ma micro inverters amagwiritsidwanso ntchito pazamalonda ndi mafakitale akuyang'ana padenga.Chaka chatha, pulojekiti ya PV yamalonda ndi mafakitale inayikidwa padenga la sitolo yaikulu ku Goits, Brazil, yomwe inayikidwa mphamvu ya 48.6 kW.Kumayambiriro kwa mapangidwe a polojekiti ndi kusankha, malowa akuzunguliridwa mu chithunzi pansipa.Kutengera izi, polojekitiyi idasankha zinthu zonse zazing'ono-inverter, kuti mphamvu yopangira gawo lililonse padenga isakhudze wina ndi mnzake, kuonetsetsa kuti dongosolo lamagetsi likuyenda bwino.
Mawonekedwe angapo akhala chinthu china chofunikira padenga la PV masiku ano, ndipo ma inverters ang'onoang'ono okhala ndi gawo la MPPT mosakayikira ndi chisankho choyenera kwambiri chothana ndi kutayika kwa mphamvu komwe kumachitika chifukwa chamitundu yosiyanasiyana.Sonkhanitsani kuwala kwa dzuwa kuti kuunikire mbali zonse za dziko lapansi.
