Kodi PV yolumikizidwa ndi gridi imalumikizidwa bwanji ndi gridi?

Pankhani ya kusintha kwa mphamvu masiku ano, mphamvu ya photovoltaic, monga mphamvu yoyera ndi yowonjezereka, ikugwiritsidwa ntchito kwambiri. Kabati yolumikizidwa ndi grid ya malo opangira magetsi a photovoltaic ndi zida zofunikira zolumikizira dongosolo la photovoltaic ndi gridi yamagetsi, ndipo kufunikira kwake kumawonekera.

Choyamba, mfundo yogwirira ntchito ya nduna yolumikizidwa ndi grid ya malo opangira magetsi a photovoltaic
Kutembenuza mphamvu zamagetsi ndi kutumiza
Ma sola amagetsi amagetsi a photovoltaic amasintha mphamvu ya dzuwa kukhala yachindunji. DC ikasonkhanitsidwa kudzera mu bokosi la basi, imalowa mu inverter. Inverter imatembenuza chiwongolero chamakono kukhala chosinthira, ndipo zotulutsa zake zosinthira zimakhala ndi ma frequency ndi gawo lofanana ndi gridi yamagetsi.
Mphamvu ya AC yotembenuzidwa ndi inverter imalowa mu kabati yolumikizidwa ndi grid ya malo opangira magetsi a photovoltaic. Chowotcha chigawo ndi chosinthira chodzipatula mu nduna yolumikizidwa ndi grid ali ndi udindo wowongolera njira yotumizira mphamvu yamagetsi. Chilichonse chikakhala chachilendo, wowononga dera amatsekedwa, ndipo njira yosinthira imatumizidwa ku gridi kudzera mu grid cabinet.

Kukhazikitsa ntchito yachitetezo
Chitetezo chambiri: Pakalipano ikadutsa mtengo wokhazikitsidwa, chipangizo chachitetezo cha overcurrent chidzachitapo kanthu mwachangu kuti chidule dera. Izi nthawi zambiri zimadutsa pa thiransifoma yamakono kuti izindikire kukula kwamakono, pamene zamakono zimadutsa malire oikika, zomwe zimayambitsa ulendo wodutsa dera.
Chitetezo cha Overvoltage: Mphamvu ya gridi yamagetsi ikakwera kwambiri, chipangizo choteteza ku overvoltage chimayamba kuletsa zida kuti zisawonongeke chifukwa chakuchulukirachulukira. Chitetezo cha overvoltage chimatha kuzindikira mphamvu ya gridi yamagetsi kudzera pa thiransifoma voteji, voteji ikadutsa mtengo wokhazikitsidwa, kuyambitsa ulendo wophwanya dera kapena kutumiza chizindikiro cha alamu.
Chitetezo cha Undervoltage: Mosiyana ndi chitetezo cha overvoltage, pamene magetsi a gridi ali otsika kwambiri, chipangizo chotetezera chopanda mphamvu chidzagwira ntchito kuteteza kukhazikika kwa zipangizo ndi grid. Momwemonso, chitetezo cha undervoltage chimazindikiranso mphamvu ya gridi yamagetsi kudzera pa transformer yamagetsi, ndikuyambitsa chitetezo chofananira pomwe voteji ili yotsika kuposa mtengo wokhazikitsidwa.
Kuteteza kwakanthawi: Kuwonongeka kwafupipafupi kumachitika m'derali, chipangizo chotetezera chachifupi chimadula nthawi yomweyo kuti chiteteze kukula kwa vutolo. Chitetezo chozungulira chachifupi nthawi zambiri chimatheka ndi ma fuse othamanga kapena owononga ma circuit.

Ntchito zowunika ndi kuwongolera
Kabati yolumikizidwa ndi grid ya malo opangira magetsi a photovoltaic imakhala ndi zida zosiyanasiyana ndi masensa kuti aziwunika nthawi yeniyeni yamagetsi, zamakono, mphamvu, ma frequency ndi magawo ena. Zigawozi zikhoza kuwonetsedwa kwa wogwiritsa ntchito pogwiritsa ntchito chinsalu chowonetsera kapena njira yoyankhulirana yakutali kuti amvetse nthawi yake momwe ntchito yamagetsi ya photovoltaic imagwirira ntchito.
Dongosolo lowongolera limatha kuwongolera patali ndikusintha malo opangira magetsi a photovoltaic molingana ndi magawo omwe amayang'aniridwa. Mwachitsanzo, pamene magetsi a gridi ali okwera kwambiri, mphamvu yotulutsa mphamvu ya photovoltaic imatha kuchepetsedwa kupyolera mu dongosolo lolamulira; Ma frequency a gridi akakhala osakhazikika, ma frequency a inverter amatha kusinthidwa kuti agwirizane ndi ma frequency a grid.
Chachiwiri, njira yolumikizira kabati yolumikizidwa ndi grid ya malo opangira magetsi a photovoltaic ndi gridi yamagetsi

Kulumikizana kwa gridi molunjika
Kulumikizana kwa gridi ndi njira yodziwika kwambiri yolumikizira. Munjira yolumikizira iyi, kabati yolumikizidwa ndi grid ya malo opangira magetsi a photovoltaic imalumikizidwa mwachindunji ndi mzere wapakati kapena wochepera wamagetsi a gridi yamagetsi kudzera pamagetsi ozungulira, chosinthira chodzipatula ndi zida zina.
Ubwino wa kulumikizana kwa gridi mwachindunji ndi mawonekedwe osavuta, otsika mtengo komanso okwera kwambiri. Komabe, njira yolumikizira iyi ili ndi zofunika kwambiri pakutulutsa mphamvu yamagetsi amagetsi a photovoltaic, ndipo iyenera kukwaniritsa zofunikira ndi zofunikira za gridi. Panthawi imodzimodziyo, kugwirizana kwa gridi molunjika kumafunikanso kuganizira kukhazikika ndi kudalirika kwa gridi yamagetsi kuti tipewe zotsatira zoipa pa gridi yamagetsi.

Kulumikizidwa ku gridi ndi transformer
Kulumikizana kwa transformer ndiko kulumikiza chosinthira pakati pa malo opangira magetsi a photovoltaic ndi gridi yamagetsi. Ma Transformers amatha kukweza kapena kutsitsa mphamvu yamagetsi yamagetsi yamagetsi a photovoltaic mpaka mulingo wamagetsi womwe umafanana ndi gululi.
Ubwino wolumikiza gululi kudzera pa thiransifoma ndikuti imatha kusintha mphamvu yamagetsi yamagetsi amagetsi a photovoltaic, kuchepetsa kutayika kwa mzere, komanso kutenga gawo lodzipatula komanso chitetezo. Komabe, njira yolumikizira iyi ndi yokwera mtengo, imatenga malo ambiri, ndipo kutayika kwa thiransifoma kudzachepetsanso mphamvu yonse ya magetsi a photovoltaic.

Kulumikizana kwa Microgrid
Microgrid ndi kachitidwe kakang'ono kamagetsi kamene kamapangidwa ndi magetsi ogawidwa, chipangizo chosungira mphamvu ndi katundu. Malo opangira magetsi a photovoltaic amatha kulumikizidwa ku microgrid kudzera mu kabati yolumikizidwa ndi gridi ndikukhala gawo la microgrid.
Njira yolumikizira ma microgrid imatha kusintha kudalirika komanso kukhazikika kwa malo opangira magetsi a photovoltaic, komanso imatha kugwiritsa ntchito bwino ndikuwongolera mphamvu. Mu ma microgrids, zomera za photovoltaic zimatha kugwira ntchito limodzi ndi magwero ena amagetsi omwe amagawidwa kuti akwaniritse zosowa za katundu wamba. Microgrid ikalumikizidwa ndi gridi yayikulu, kuyenderera kwamphamvu kwapawiri kumatha kuzindikirikanso kuti kuwongolera kugwiritsa ntchito mphamvu kwamphamvu.

Kukhazikitsa ndi kukonza kabati yolumikizidwa ndi grid ya malo opangira magetsi a photovoltaic
Zofunikira pakukhazikitsa
Kuyika kwa makabati olumikizidwa ndi grid a malo opangira magetsi a photovoltaic akuyenera kutsatira malamulo ndi miyezo yoyenera yachitetezo chamagetsi. Malo oyikapo akuyenera kukhala pamalo owuma, olowera mpweya wabwino komanso osavuta kugwiritsa ntchito komanso kukonza.
Kabati yolumikizidwa ndi gridi iyenera kukhazikitsidwa bwino komanso yokhazikika. Zingwe ziyenera kulumikizidwa bwino kuti zipewe zolakwika monga kufupikitsa ndi kuyika pansi.
Pakuyika, chisamaliro chiyenera kuperekedwa pakuteteza zida ndi mita mu kabati yolumikizidwa ndi gridi kuti zisawonongeke. Nthawi yomweyo, kuyezetsa kolimba kwamagetsi ndi kukonza zolakwika kuyeneranso kuchitidwa kuti zitsimikizire kuti ntchito za kabati yolumikizidwa ndi gridi ndizabwinobwino.
kusamalira
Yang'anani ndikusunga kabati yolumikizidwa ndi grid ya malo opangira magetsi a photovoltaic pafupipafupi, kuphatikiza zida zoyeretsera, kuyang'ana zolumikizira zingwe, zida zodzitetezera, ndi zina zambiri.
Onani momwe kabati yolumikizidwa ndi gridi ikugwirira ntchito. Ngati vuto linalake lapezeka, lithetseni nthawi yake. Mwachitsanzo, pamene wophwanyira dera akugwedezeka, chiwonetsero cha chida ndi chachilendo, ndi zina zotero, chiyenera kuyang'aniridwa ndi kukonzedwa mwamsanga.
Zida ndi zida zomwe zili mu nduna yolumikizidwa ndi gridi zimayesedwa ndikuyesedwa pafupipafupi kuti zitsimikizire kuti ndizolondola komanso zodalirika.
Limbikitsani kasamalidwe ka chitetezo cha makabati olumikizidwa ndi gridi kuti mupewe anthu omwe si akatswiri kuti asagwiritse ntchito molakwika kapena kuwononga zida.
