Intelligent PV Panel Junction Box Imathetsa Mavuto Atatu Akuluakulu Omwe Akuvutitsa Makampani a PV

M'zaka zapitazi za 10, zopangira magetsi za photovoltaic zakhala zikudziwika kwambiri padziko lonse lapansi, ndipo zatsopano zozungulira mafakitale a photovoltaic zimawonekera mosalekeza.Njira zatsopanozi zalimbikitsa kuwongolera kosalekeza kwa machitidwe opangira magetsi a photovoltaic, kutsika mtengo, ndikupanga dongosolo la photovoltaic kukhala lokhazikika komanso loyandikira miyoyo ya okhalamo.

Mwa njira zatsopanozi, R&D yanzeru yamakina opangira magetsi a photovoltaic yakhala imodzi mwazofunikira kwambiri pazatsopano zaukadaulo padziko lonse lapansi.Makampani ena ochita upainiya opanga ma photovoltaic ndi mabungwe ofufuza amagwiritsa ntchito ukadaulo wa pa intaneti, ukadaulo wa sensa, kusanthula kwakukulu kwa data, ndi zina zambiri kuti alumikizitse makina opangira magetsi amtundu wa photovoltaic kuti athandizire osunga ndalama kuti azitha kukonza chitetezo chatsiku ndi tsiku ndikuwunika momwe ndalama zimakhalira.

Kupanga maziko a mphamvu ya dzuwa - ma solar panels, imakhala ndi ntchito yayikulu yolandira kuwala ndikusintha mphamvu ya kuwala kukhala mphamvu yamagetsi.Komabe, kwa zaka zambiri, ambiri otchedwa anzeru photovoltaic mphamvu zomera amene amati anaika wanzeru kasamalidwe nsanja akadali sanaone zizindikiro za "luntha" pa mfundo mlingo wa mphamvu m'badwo core modules (mapanelo).Ma solar panel amangolumikizidwa mndandanda ndi oyikapo kuti apange chingwe, ndipo zingwe zingapo zimalumikizidwa kuti apange gulu la photovoltaic, lomwe pamapeto pake limapanga dongosolo lamagetsi.

Ndiye, kodi pali vuto lililonse ndi dongosololi?

Choyamba, voteji ya gulu lililonse photovoltaic si mkulu, makumi angapo volts, koma voteji mu mndandanda ndi mkulu monga za 1000V.Pamene magetsi opangira magetsi akukumana ndi moto, ngakhale ozimitsa moto amatha kulumikiza kusintha kwa dera lobwereranso kwa dera lalikulu, dongosolo lonselo limakhala loopsa kwambiri, chifukwa ndilokhalo lomwe liri mu dera lobwereza lomwe lazimitsidwa.Chifukwa mapanelo a dzuwa amalumikizidwa wina ndi mnzake ndi zolumikizira, voteji ya dongosolo pansi ikadali 1000V.Pamene ozimitsa moto osadziwa amatha mfuti zamadzi zothamanga kwambiri kuti azipopera madzi pamabodi opangira mphamvu za 1000V, chifukwa madziwa ndi oyendetsa, kusiyana kwakukulu kwa magetsi kumayendetsedwa mwachindunji kwa ozimitsa moto kupyolera mumtsinje wamadzi, ndipo tsoka lidzachitika.

Chachiwiri, zotulukapo za gulu lililonse la photovoltaic ndizosagwirizana, monga panopa, magetsi ndi malo abwino ogwiritsira ntchito.Pogwiritsa ntchito nthawi yayitali komanso kukalamba kwachilengedwe kwa machitidwe a photovoltaic kunja, kusagwirizana kumeneku kudzakhala koonekeratu.Makhalidwe opangira magetsi a tandem amagwirizana ndi "barrel effect".Mwa kuyankhula kwina, mphamvu yonse yopanga mphamvu ya chingwe cha solar panels imadalira kwambiri zomwe zimachokera ku gulu lofooka kwambiri mu chingwe.

Chachitatu, mapanelo adzuwa amawopa kwambiri kutsekeka kwa mthunzi (zomwe zimatsekeka nthawi zambiri zimakhala mthunzi wamitengo, zitosi za mbalame, fumbi, chimneys, zinthu zakunja, ndi zina), kotero nthawi zambiri zimayikidwa m'malo adzuwa, koma m'malo opangira magetsi padenga. kuti aganizire kukongola ndi kugwirizana kwa nyumba yonse ndi nyumba yomanga bwalo, eni ake nthawi zambiri amafalitsa mapanelo a batri padenga lonse.Ngakhale kuti mbali zina za madengawa zingayambitse kutsekeka kwa mthunzi, nthawi zina, eni ake samamvetsetsa bwino zomwe zimachitika komanso kuvulaza kwa mthunzi wa mthunzi pazitsulo zamagetsi.Popeza gulu la batri limakutidwa ndi mithunzi, chinthu chodzitchinjiriza (nthawi zambiri diode) mu bokosi la PV panel junction kuseri kwa gululi chidzapangitsidwa, ndipo DC yapano mpaka pafupifupi 9A mu chingwe cha batri idzakwezedwa nthawi yomweyo podutsa. chipangizo, kupanga PV mphambano bokosi Padzakhala kutentha kwambiri kuposa madigiri 100 mkati.Kutentha kwakukulu kumeneku sikudzakhala ndi zotsatira zochepa pa bolodi la batri ndi bokosi lolumikizirana pakanthawi kochepa, koma ngati mthunzi suchotsedwa ndipo umakhalapo kwa nthawi yayitali, umakhudza kwambiri moyo wautumiki wa bokosi lolumikizirana ndi batire. .

Kuphatikiza apo, mithunzi ina imakhala yachitetezo chobwerezabwereza mobwerezabwereza (mwachitsanzo, nthambi zomwe zili kutsogolo kwa denga la nyumba ya photovoltaic zimatsekereza gulu la batri mobwerezabwereza ndi mphepo. conduction - kuchotsedwa).Diode imayatsidwa ndikutenthedwa ndi mphamvu yamphamvu kwambiri, ndiyeno kukondera kumasinthidwa nthawi yomweyo kuti aletse zomwe zikuchitika ndikuwonjezera mphamvu yakumbuyo.Mu kuzungulira mobwerezabwereza uku, moyo wautumiki wa diode umachepetsedwa kwambiri.Diode yomwe ili mu bokosi la PV panel junction ikawotcha, kutulutsa kwapagulu lonse la solar kudzalephera.

Choncho, kodi pali njira yothetsera mavuto atatuwa panthawi imodzi?Engineers anatulukirawanzeru PV mphambano bokosipambuyo pa zaka zolimbikira ntchito ndi kuchita.

Bokosi ili la Slocable PV junction limagwiritsa ntchito chipangizo cha DC photovoltaic power management chip kupanga ndi kumanga bolodi loyang'anira dera, lomwe lingathe kuikidwa mwachindunji mu bokosi la photovoltaic junction.Pofuna kuwongolera kuyika kwa opanga magetsi a solar, kapangidwe kake kasungitsa ma wiring anayi a mabasi, kotero kuti bokosi lolumikizana litha kulumikizidwa mosavuta ndi solar panel, ndi zotuluka.zingwendizolumikiziraamaikidwa kale asanachoke kufakitale.Bokosi lophatikizika ili pano ndilosavuta kwambiri la PV intelligent junction box mumakampani a photovoltaic kukhazikitsa ndi kukonza.Makamaka amapereka njira zothetsera mavuto atatu omwe ali pamwambawa omwe akuvutitsa makampani a photovoltaic.Lili ndi ntchito zotsatirazi:

1) MPPT ntchito: Kupyolera mu mgwirizano wa mapulogalamu ndi hardware, gulu lililonse ali okonzeka ndi pazipita mphamvu kutsatira luso ndi kulamulira zipangizo.Ukadaulo uwu ukhoza kukulitsa kuchepetsedwa kwa mphamvu yopangira magetsi chifukwa cha mawonekedwe osiyanasiyana pamagawo ndikuchepetsa ” Zotsatira za "mbiya yamadzi" pakuchita bwino kwa malo opangira magetsi zitha kupititsa patsogolo mphamvu yakupangira magetsi pamalo opangira magetsi.Kuchokera pazotsatira zoyeserera, mphamvu yopangira mphamvu yamakina imatha kukulitsidwa ndi 47.5%, zomwe zimawonjezera ndalama zogulira ndikuchepetsa kwambiri nthawi yobwezera ndalama.

2) Kutsekera kwanzeru pazikhalidwe zachilendo monga moto: Pakakhala moto, pulogalamu yokhazikika ya PV panel junction box ndi gawo la hardware limatha kudziwa ngati cholakwika chachitika mkati mwa 10 milliseconds, ndikudulidwa mwachangu. kugwirizana pakati pa gulu lililonse la batri.Magetsi a 1000V amachepetsedwa kukhala magetsi ovomerezeka ku thupi la munthu mozungulira 40V kuti atsimikizire chitetezo cha ozimitsa moto.

3) MOSFET thyristor Integrated control technology imagwiritsidwa ntchito m'malo mwachikhalidwe cha Schottky diode.Pamene mthunzi watsekedwa, MOSFET bypass panopa ikhoza kuyambika nthawi yomweyo kuteteza chitetezo cha batri.Nthawi yomweyo, chifukwa cha mawonekedwe otsika a VF a MOSFET, kutentha komwe kumapangidwa mubokosi lonse lolumikizana ndi gawo limodzi mwa magawo khumi a bokosi lolumikizira wamba.Ukadaulo uwu kwambiri Moyo wautumiki wa bokosi lolumikizirana la photovoltaic umatalika, ndipo moyo wautumiki wa gulu la solar umatsimikiziridwa bwino.

Pakadali pano, mayankho aukadaulo a mabokosi anzeru a PV akutuluka motsatana, makamaka mozungulira kukhathamiritsa ndi kuwongolera mphamvu zamagetsi zamtundu wa photovoltaic, ndikuwongolera njira zoyankhira moto za photovoltaic monga ntchito zotseka.

Kupanga ndi kupanga "bokosi lanzeru la PV" si ntchito yovuta komanso yozama.Komabe, bokosi lophatikizana lanzeru lingakwaniritse bwanji zowawa ndi zovuta za msika wa photovoltaic?Ndikofunikira kuti mupeze bwino bwino potengera momwe magetsi amagwirira ntchito pabokosi lolumikizirana, moyo wautumiki wa zida zamagetsi, mtengo ndi ndalama zogulira bokosi lanzeru.Amakhulupirira kuti m'zaka zingapo zikubwerazi, bokosi lanzeru la PV junction lidzakhala ndi ntchito zambiri mu photovoltaic system ndikupanga phindu lalikulu kwa osunga ndalama.
