Chosinthira magetsi adzuwa ndi chosinthira chamagetsi chomwe chimagwiritsidwa ntchito mumagetsi a photovoltaic kuti asinthe ma voltage, kuthandizira kulumikizana ndi gridi, kupereka kudzipatula kwamagetsi, ndikuthandizira kusamutsa magetsi opangidwa ndi sola mosamala komanso moyenera. Amagwiritsidwa ntchito kwambiri pakati pa ma solar inverters, zida zogawa, ndi gridi yogwiritsira ntchito.
Mu ntchito ya dzuwa, ma module a photovoltaic amapanga magetsi a DC. Inverter imatembenuza mphamvu ya DC kukhala mphamvu ya AC. Pambuyo pa kutembenuka, magetsi a AC angafunikire kukwera kapena kusinthidwa asanayambe kugwiritsidwa ntchito ndi malo kapena kuperekedwa ku gridi. Apa ndi pamene a thiransifoma ya dzuwa amachita mbali yofunika.
Chifukwa Chake Ma Solar Power Systems Amafunikira Zosintha
Zopangira magetsi a dzuwa ndi malonda a photovoltaic systems nthawi zambiri zimapanga magetsi pamagetsi omwe sagwirizana ndi grid kapena malo ogawa magetsi. Transformer imathetsa vutoli pokweza ma voltage m'mwamba kapena pansi.
Mwachitsanzo, inverter imatha kutulutsa ma AC otsika kwambiri monga 400V, 480V, 600V, kapena 800V. Transformer imatha kukweza mphamvuyi mpaka voteji yapakati, monga 6kV, 10kV, 11kV, 13.8kV, 33kV, kapena mulingo wina wofunikira pa gridi.
Kusintha kwamagetsi kumeneku kumathandizira kuchepetsa zomwe zikuchitika panthawi yotumizira, kutsika kwa chingwe, ndikupangitsa kuti solar igwirizane ndi zomangamanga zamagetsi zakomweko.
Momwe Chosinthira Mphamvu ya Dzuwa Zimagwirira Ntchito
Transformer imagwira ntchito pogwiritsa ntchito electromagnetic induction. Ili ndi ma windings oyambirira ndi achiwiri omwe amaikidwa mozungulira maginito. AC ikadutsa pamapiringa oyamba, imapanga mphamvu yamaginito. Gawo ili limapangitsa kuti ma voltage mu mafunde achiwiri.
Kutembenuka kwapakati pa ma windings kumatsimikizira ngati thiransifoma ikukwera kapena kutsika.
Pamagetsi a dzuwa, thiransifoma imatha kugwira ntchito zingapo:
- Onjezani mphamvu ya inverter kuti mulumikizane ndi grid
- Tsitsani mphamvu yamagetsi pa katundu wapafupi
- Perekani kudzipatula pakati pa inverter ndi gridi
- Thandizani dongosolo loyambira pansi
- Chepetsani kusokonezeka kwina kwamagetsi
- Sinthani kugwirizanitsa ndi switchgear ndi chitetezo machitidwe
A thiransifoma ya dzuwa ziyenera kusankhidwa molingana ndi inverter, magetsi a gridi, mphamvu yamakina, ndi momwe malo alili.
Mitundu Yaikulu Ya Ma Transformers Omwe Amagwiritsidwa Ntchito Pamapulojekiti a Dzuwa
Inverter Step-Up Transformer
Ichi ndi chimodzi mwa mitundu yodziwika bwino ya ma transfoma m'mafakitale amagetsi adzuwa. Imakweza voteji ya AC kuchokera pa inverter kupita pamlingo wapakati-voltage woyenera makina osonkhanitsira kapena kulumikizana ndi grid.
Pad-Mounted Transformer
Magetsi okhala ndi pad amagwiritsidwa ntchito panja m'mafamu adzuwa amalonda komanso othandiza. Amayikidwa pazitsulo za konkriti ndikugwirizanitsa ndi zingwe zapansi kapena pamwamba.
Dry-Type Transformer
Ma transfoma owuma amagwiritsa ntchito kuzirala kwa mpweya ndi kutchinjiriza kolimba m'malo mwa mafuta. Nthawi zambiri amagwiritsidwa ntchito m'nyumba kapena m'malo omwe mafuta amakhala ndi nkhawa.
Transformer Yomizidwa ndi Mafuta
Ma transfoma omizidwa ndi mafuta amagwiritsa ntchito mafuta oteteza kuziziritsa ndi kutchinjiriza. Amagwiritsidwa ntchito kwambiri m'mapulojekiti akuluakulu akunja kwa dzuwa chifukwa amatha kugwira ntchito zapamwamba komanso kupereka magwiridwe antchito amafuta.
Kudzipatula Transformer
Transformer yodzipatula imalekanitsa mabwalo amagetsi posamutsa mphamvu. M'malo opangira dzuwa, atha kugwiritsidwa ntchito pomwe pakufunika kudzipatula kwamagetsi, kuwongolera pansi, kapena kugwiritsa ntchito zida.
Zofunika Kwambiri za Solar Power Transformer
Kugwiritsa ntchito dzuwa kumapanga zochitika zenizeni zogwirira ntchito, kotero kuti mapangidwe a transformer amafunikira.
Zofunikira ndi izi:
- Kuchita bwino kwambiri
- Zokwanira ma voltage ratio
- Kukwanira kwa kVA kapena MVA
- Kugwirizana ndi kutulutsa kwa inverter
- Dongosolo lolimba la insulation
- Kapangidwe kozizira koyenera
- Zotayika zochepa
- Makonzedwe apansi ogwirizana ndi gridi
- Kuteteza nyengo panja pakufunika
- Kukaniza ma harmonics ndi kupsinjika kwamafuta
- Mgwirizano wodalirika wachitetezo
- Moyo wautali wautumiki
Because solar production changes throughout the day, the transformer may experience fluctuating loads. Iyenera kugwira ntchito mogwira mtima osati pakudzaza kwathunthu, komanso pansi pamikhalidwe yolemetsa pang'ono.
Solar Transformer vs. Standard Transformer
Transformer ya solar ikhoza kuwoneka yofanana ndi yogawa yogawa, koma momwe ntchito zake zimagwirira ntchito zimatha kukhala zosiyana.
Ma transfoma a solar nthawi zambiri amagwira ntchito ndi:
- Kusintha kochulukira pafupipafupi
- Ma harmonics opangidwa ndi inverter
- Kutulutsa kwakukulu kwa masana komanso kutsika kwapakati pausiku
- Kuwonekera panja
- Zofunikira zolumikizana ndi gridi
- Bwezerani mayendedwe amagetsi muzinthu zina
- Kutenthetsa njinga
- Malo oyika akutali
Pazifukwa izi, kusankha kwa thiransifoma kuyenera kuganizira za mphamvu zonse za solar, osati ma voltage ndi mphamvu.
Momwe Mungakulire Chosinthira Mphamvu ya Dzuwa
Kukula kumadalira kuchuluka kwa inverter yonse, voteji ya AC, mphamvu yamagetsi, voteji ya gridi, kufunikira kochulukira, kutentha kozungulira, ndi kapangidwe ka makina.
Chisankho choyenera chiyenera kuwunikiranso:
- Kuchuluka kwa inverter AC
- Voltage yoyamba
- Mphamvu yachiwiri
- Gawo ndi pafupipafupi
- kVA kapena MVA mlingo
- Kusokoneza
- Njira yozizira
- Kutentha kumakwera
- Zinthu za Harmonic
- Njira yokhazikitsira pansi
- Zida zoteteza
- Utali woyika
- Kutentha kozungulira
- Malo amkati kapena kunja
- Miyezo yovomerezeka
Transformer yomwe ili yaying'ono kwambiri imatha kutentha kwambiri kapena kuchepetsa kutulutsa kwadongosolo. Transformer yomwe ndi yayikulu kwambiri imatha kukulitsa mtengo ndikuchepetsa mphamvu pakulemera kwake. Kukula kwabwino kumayenderana ndi chitetezo, magwiridwe antchito, komanso kugwira ntchito kwanthawi yayitali.
Kumene Ma Transformers A Mphamvu ya Dzuwa Amagwiritsidwa Ntchito
Zosintha zamagetsi za solar zitha kupezeka m'mapulogalamu ambiri a photovoltaic, kuphatikiza:
- Utility-scale solar farms
- Machitidwe a PV padenga lamalonda
- Industrial solar systems
- Mapulojekiti a Solar-plus-storage
- Ma Microgrids
- Agricultural solar installs
- Ma solar okwera pansi
- Machitidwe amphamvu a Hybrid renewable
- Ma inverter olumikizidwa ndi ma gridi
M'magawo ang'onoang'ono okhalamo, chosinthira chosiyana sichingawonekere nthawi zonse chifukwa ma inverter ndi mawonekedwe a gridi amatha kuthana ndi zofunikira zamagetsi mosiyana. M'makina akuluakulu, ma transformer nthawi zambiri amakhala ofunikira.
Zolinga Zosamalira
A thiransifoma ya dzuwa ziyenera kuyang'aniridwa nthawi zonse kuti zikhale zotetezeka komanso zogwira ntchito. Zofunikira pakukonza zimasiyana malinga ndi mtundu wa transformer ndi malo oyika.
Macheke wamba ndi awa:
- Kuwunika kwa kutentha
- Mulingo wamafuta ndi momwe mafuta amapangira magawo odzaza mafuta
- Insulation resistance
- Kulumikizana mwamphamvu
- Kuyika pansi
- Mkhalidwe wa dongosolo lozizirira
- Phokoso ndi kunjenjemera
- Zizindikiro za kutentha kwambiri
- Kulowa kwa chinyezi
- Zimbiri
- Ntchito yoteteza chipangizo
Kukonzekera koyenera kungachepetse nthawi yopuma ndikuwonjezera moyo wautumiki wa transformer.
Zolakwa Zomwe Muyenera Kuzipewa
Cholakwika chimodzi chofala ndikusankha thiransifoma yongotengera mphamvu. Chiyerekezo chamagetsi, impedance, grounding, harmonics, zotayika, ndi malo oyika nawonso ndizofunikira.
Kulakwitsa kwina ndikunyalanyaza mawonekedwe a inverter. Kutulutsa kwa inverter kumatha kukhala ndi zigawo za harmonic ndi zosintha zomwe zimafuna mawonekedwe oyenera a thiransifoma.
Kulakwitsa kwachitatu ndikunyalanyaza magwiridwe antchito pakulemetsa pang'ono. Ma sola a dzuwa amatha kugwira ntchito mosiyanasiyana, kotero kuti kuchepa kwapang'onopang'ono kumatha kukhudza zokolola zanthawi yayitali.
Mapeto
Chosinthira magetsi adzuwa ndi chinthu chofunikira kwambiri chamagetsi chomwe chimasintha ma voltages, chimathandizira kulumikizana ndi gridi, chimapereka kudzipatula, ndikuthandizira mphamvu yadzuwa kuyenda bwino kuchokera ku ma inverter kupita kwa ogwiritsa ntchito kapena maukonde othandizira.
Ufulu thiransifoma ya dzuwa ziyenera kufanana ndi mphamvu ya photovoltaic system, kutulutsa kwa inverter, magetsi a gridi, njira yokhazikitsira pansi, zofunikira zoziziritsa, ndi malo a malo. Kusankha kosinthika kosintha kumawongolera kudalirika kwadongosolo, mphamvu zamagetsi, komanso magwiridwe antchito anthawi yayitali a solar.
Kuti mudziwe zambiri zamtundu wamagetsi amagetsi a solar, pitani JS Ndinyi.
