Yakangwara PV Panel Junction Bhokisi Inogadzirisa Matambudziko Makuru Matatu Anotambudza Indasitiri yePV

Mumakore ekupedzisira e10, photovoltaic simba rekugadzira zvigadzirwa zvave zvichinyanya kufarirwa pasi rose, uye zvitsva zvakapoteredza photovoltaic industry inobuda mukusingaperi.Aya matanho matsva akakurudzira kuenderera mberi kwekuvandudzwa kwesimba remagetsi ekugadzira photovoltaic, kuderera kwemitengo, uye kuita kuti photovoltaic system iwedzere kudzika uye pedyo nehupenyu hwevagari.

Pakati peaya matanho ekuvandudza, iyo yakangwara R&D yephotovoltaic magetsi ekugadzira masisitimu yave imwe yezvinonetsa zvepasi rose tekinoroji innovation.Mamwe makambani ekupayona photovoltaic uye masangano ekutsvagisa anoshandisa tekinoroji yeInternet, tekinoroji ye sensor, ongororo huru yedata, nezvimwe kubatanidza iyo yakasarudzika photovoltaic magetsi chiteshi masisitimu kubatsira vanoisa mari kuita zviri nyore kuchengetedza kuchengetedza zuva nezuva uye sarudzo dzekuongorora mari.

Kugadzira musimboti wesimba rezuva - solar panels, inotakura basa rekutanga rekugamuchira chiedza uye kushandura simba rechiedza kuita simba remagetsi.Nekudaro, nekufamba kwemakore, mazhinji anonzi akangwara photovoltaic magetsi maplants ayo aiti akaisa akangwara manejimendi chikuva haasati aona chero maratidziro e "njere" padanho rekutanga remagetsi ekugadzira core modules (mapaneru).Iwo solar panel anongobatanidzwa munhevedzano nemuisi kuti aite tambo, uye tambo dzinoverengeka dzakabatanidzwa kuti dzigadzire photovoltaic array, iyo inozopedzisira yaumba chiteshi chemagetsi system.

Saka, pane dambudziko here nehurongwa uhu?

Kutanga, iyo voltage yega yega photovoltaic panel haina kukwirira, mashoma makumi mashoma evolts, asi iyo voltage munhevedzano yakakwira senge 1000V.Apo simba rekugadzira hurongwa rinosangana nemoto, kunyange kana vadzimi vemoto vanogona kubvisa shanduko yekudzoka redunhu redunhu guru, iyo yose hurongwa ichiri nengozi zvikuru, nokuti inongova ikozvino munharaunda yekudzoka iyo inodzimwa.Nekuda kwekuti solar panels dzakabatana nekubatanidza, voltage ye system kusvika pasi ichiri 1000V.Kana vadzimi vemoto vasina ruzivo vanopedzisa pfuti dzemvura dzepamusoro-soro kupfapfaidza mvura pamapuranga aya emagetsi e1000V, nekuti mvura inofambisa, musiyano mukuru wevoltage unotakurwa zvakananga kune vanodzima moto kuburikidza nekoramu yemvura, uye njodzi ichaitika.

Chechipiri, maitiro ekubuda kwega yega photovoltaic panel hazvienderani, zvakadai sezvino, voltage uye optimal operating point.Nekushandiswa kwenguva refu uye kuchembera kwechisikigo kwe photovoltaic systems kunze, kusawirirana uku kuchava pachena.Hunhu hwe tandem kugadzirwa kwemagetsi kunoenderana ne "barrel effect".Mune mamwe mazwi, iyo yakazara simba rekugadzira tambo yesolar panels inotsamira zvakanyanya pane inobuda maitiro eiyo isina kusimba pani mutambo.

Chechitatu, solar panels anotya zvakanyanya kuvharika kwemumvuri (izvo zvinovharika zvinowanzo mumvuri wemuti, madonhwe eshiri, guruva, chimneys, zvinhu zvekunze, nezvimwewo), saka anowanzo kuisirwa munzvimbo dzine zuva, asi mune akagoverwa padenga remagetsi masisitimu. kuti utarise kunaka uye kurongeka kweimba yese uye chivanze chivakwa chechivanze, varidzi vanowanzoparadzira bhatiri mapaneru zvakaenzana padenga rose.Kunyangwe zvimwe zvikamu zvematenga aya zvinogona kukonzera kuvharika kwemumvuri, dzimwe nguva, varidzi havanzwisise zvizere kukanganisa kwakakomba uye kukuvadza kwekuvharika kwemumvuri pamapaneru emagetsi.Sezvo bhatiri pani rakafukidzwa nemimvuri, iyo bypass yekudzivirira chinhu (kazhinji diode) muPV panel junction bhokisi kuseri kwepanera ichave yakanyengerwa, uye iyo DC iripo kusvika pa9A mubhatiri tambo ichatakurwa ipapo ipapo. mudziyo, kugadzira iyo PV junction bhokisi Pachave nekupisa kwakanyanya kweanopfuura 100 madhigirii mukati.Iyi tembiricha yepamusoro ichange iine mhedzisiro pabhodhi rebhatiri uye bhokisi rekusangana munguva pfupi, asi kana mumvuri mhedzisiro isina kubviswa uye iripo kwenguva yakareba, ichakanganisa zvakanyanya hupenyu hwebasa rejunction bhokisi uye bhatiri bhodhi. .

Uyezve, mimwe mimvuri ndeyepamusoro-frequency inodzokororwa inodzivirira (somuenzaniso, matavi ari pamberi peimba photovoltaic denga acharamba achivhara bhatiri pani nemhepo. Iyi yakakwirira-frequency alternating shielding inoita iyo bypass mudziyo mukutenderera: disconnection - conduction - disconnection).Iyo diode inobatidzwa uye inopisa ne-high-simba ikozvino, uye ipapo kurerekera kunodzoserwa ipapo ipapo kudzima ikozvino uye kuwedzera reverse voltage.Muchikamu ichi chinodzokororwa, hupenyu hwebasa hwe diode hwakaderedzwa zvikuru.Kana iyo diode iri muPV panel junction bhokisi yatsva, iyo system inobuda yesolar panel yese inotadza.

Saka, pane mhinduro inogona kugadzirisa matambudziko matatu ari pamusoro panguva imwe chete?Mainjiniya vakagadziraakangwara PV junction bhokisimushure memakore ekushanda nesimba nekudzidzira.

Iyi Slocable PV junction bhokisi inoshandisa yakatsaurirwa DC photovoltaic simba manejimendi chip kugadzira uye kuvaka control redunhu bhodhi, iyo inogona kuiswa zvakananga muiyo photovoltaic junction box.Kuti kufambisa kuiswa kwevagadziri vesolar panel, dhizaini yakachengetera mana mabhazi-bhendi wiring outlets, kuitira kuti bhokisi rejunction ribatanidzwe nyore kune solar panel, uye kubuda.cablesuyeconnectorsdzinoiswa kare dzisati dzabuda mufekitari.Iri junction bhokisi parizvino ndiyo yakanyanya nyore PV yakangwara junction bhokisi mune photovoltaic indasitiri yekuisa nekuchengetedza.Iyo inonyanya kupa mhinduro kune matatu ari pamusoro apa matambudziko makuru matatu anotambudza iyo photovoltaic industry.Iine mabasa anotevera:

1) MPPT basa: Kuburikidza nekushandira pamwe kwesoftware uye Hardware, pani yega yega inoshongedzerwa nepamusoro pesimba rekutevera tekinoroji uye midziyo yekudzora.Iyi tekinoroji inogona kukwirisa kudzikisira kwesimba rekugadzira magetsi kunokonzerwa neakasiyana mapaneru maitiro uye kuderedza "Kukanganisa kwe "barrel effect" pakushanda kwechiteshi chemagetsi kunogona kuvandudza zvakanyanya kugadzirwa kwemagetsi kwechiteshi chemagetsi.Kubva pamhedzisiro yebvunzo, simba rekugadzira simba rehurongwa rinogona kutowedzerwa ne47.5%, izvo zvinowedzera mari yekudyara uye kupfupisa zvakanyanya nguva yekubhadhara mari.

2) Hungwaru yekuvhara basa remamiriro asina kujairika akadai semoto: Kana pakaitika moto, iyo yakavakirwa-mukati software algorithm yePV panel junction bhokisi uye dhizaini yehardware inogona kuona kana kusarongeka kwakaitika mukati megumi milliseconds, uye nekuchimbidzika kucheka. kubatana pakati pebhatiri rimwe nerimwe.Iyo voltage ye1000V inoderedzwa kusvika kumagetsi anogamuchirwa kumuviri wemunhu akatenderedza 40V kuve nechokwadi chekuchengetedzwa kwevanodzima moto.

3) MOSFET thyristor yakabatanidzwa yekudzora tekinoroji inoshandiswa panzvimbo yechinyakare Schottky diode.Kana mumvuri wavharwa, iyo MOSFET bypass ikozvino inogona kutangwa ipapo kuchengetedza kuchengetedzeka kwebhatiri pani.Panguva imwecheteyo, nekuda kweiyo yakasarudzika yakaderera VF maitiro eMOSFET, kupisa kunogadzirwa mubhokisi rejunction bhokisi rinongori chikamu chimwe chete mugumi cheiyo yeyakajairwa junction bhokisi.Iyi tekinoroji zvakanyanya Hupenyu hwesevhisi ye photovoltaic junction bhokisi inorebeswa, uye hupenyu hwebasa resolar panel hunovimbiswa zviri nani.

Parizvino, zvigadziriso zvehunyanzvi zvehungwaru PV junction mabhokisi zviri kubuda imwe mushure meimwe, zvakanyanya kutenderedza optimization nekuvandudza photovoltaic tambo yekugadzira simba rekuita, uye kuvandudza photovoltaic system moto mhinduro nzira dzakadai sekuvhara mabasa.

Kugadzira uye kugadzira "yakangwara PV junction bhokisi" harisi basa rakaoma uye rakadzama.Zvisinei, iyo yakangwara junction box inogona sei kunyatsosangana nemarwadzo ekurwadziwa uye matambudziko emusika we photovoltaic?Izvo zvinodikanwa kuti uwane yakanakisa chiyero maererano nebasa remagetsi rejunction bhokisi, hupenyu hwesevhisi yemidziyo yemagetsi, mutengo uye mari yekudyara yeakangwara junction bhokisi.Zvinotendwa kuti mumakore mashoma anotevera, iyo yakangwara PV junction bhokisi ichava neakawanda maapplication muiyo photovoltaic system uye kugadzira kukosha kwakawanda kune vanoisa mari.
