Momwe mungawonjezere mabatire ku solar yomangidwa ndi grid - AC Coupling

Kuonjezera mabatire ku dongosolo la solar lomwe lilipo ndi gridi ndi njira yabwino yowonjezerera kudzidalira ndikutha kupulumutsa pamtengo wamagetsi. Nayi chiwongolero chamomwe mungawonjezere mabatire pakukhazikitsa kwanu kwa solar:
Njira #1: Kuphatikiza kwa AC
Kuti ma inverters omangidwa ndi gridi agwire ntchito, amadalira gridi yamagetsi, mosalekeza kuyang'anira magetsi a gridi ndi ma frequency. Ikapatuka kupitilira magawo omwe adayikidwa, ma inverters amazimitsa ngati njira yotetezera.
Mu makina ophatikizika a AC, cholumikizira cholumikizidwa ndi gridi chimalumikizidwa ndi inverter yakunja ndi banki ya batri. The off-grid inverter imagwira ntchito ngati gwero lachiwiri lamagetsi, makamaka kupusitsa inverter yomangidwa ndi grid kuti igwire ntchito. Kukonzekera uku kumathandizira kulipiritsa batire komanso kugwiritsa ntchito zida zofunikira ngakhale magetsi azima.
Njira yabwino kwambiri yolumikizira AC ndi Deye, Megarevo, Growatt kapena Alicosolar.
AC Coupling imapereka maubwino angapo:

Kulimba Kwambiri: Kulumikizana kwa AC kumathandizira kulimba kwa makina polola kugwiritsa ntchito zida zofunika komanso kulipiritsa mabatire panthawi yamagetsi, ndikuwonetsetsa kuti magetsi sangasokonezeke.
Kuwonjeza Kusinthasintha: Kumapereka kusinthasintha pamapangidwe adongosolo pothandizira kuphatikiza zigawo zakunja za gridi ndi makina omangidwa ndi grid, zomwe zimapereka zosankha zambiri pakuwongolera ndi kugwiritsa ntchito mphamvu.
Kuwongolera Mphamvu Kwabwino: Mwa kuphatikiza gwero lachiwiri lamagetsi ndi banki ya batri, kuphatikiza kwa AC kumathandizira kuwongolera bwino mphamvu, kukulitsa kudzigwiritsa ntchito komanso kuchepetsa kudalira grid.
Kudziyimira pawokha kwa Mphamvu Zowonjezereka: Ogwiritsa ntchito amatha kuchepetsa kudalira ma gridi ndikupeza mphamvu zodziyimira pawokha pogwiritsa ntchito mphamvu zosungidwa kuchokera ku mabatire panthawi yamagetsi otsika kapena kufunikira kwamphamvu kwambiri.
Kugwiritsa Ntchito Ma Gridi Moyenera: Kulumikizana kwa AC kumathandizira kugwiritsa ntchito bwino ma inverter omangidwa ndi gridi powonetsetsa kuti akugwirabe ntchito ngakhale pamavuto a gridi, motero kukhathamiritsa ndalama zomangira gridi.
Ponseponse, kuphatikiza kwa AC kumakulitsa kudalirika kwadongosolo, kusinthasintha, ndi kasamalidwe ka mphamvu, kupatsa ogwiritsa ntchito mphamvu zambiri pamagetsi awo ndikuchepetsa kudalira magwero akunja panthawi yozimitsa kapena nthawi yofunidwa kwambiri.

Ngakhale kuphatikiza kwa AC kumapereka maubwino osiyanasiyana, kumakhalanso ndi zovuta zina:

Kuvuta: Kulumikizana kwa AC kumaphatikizapo kuphatikiza zigawo zomangika ndi gridi, zomwe zimatha kukulitsa zovuta zamakina. Kuyika ndi kukonza kungafunike chidziwitso chapadera ndi ukatswiri, zomwe zingapangitse kuti pakhale mitengo yokwera.
Mtengo: Kuphatikizika kwa zida zakunja za gridi monga ma inverters ndi mabanki a batri kumatha kukulitsa mtengo wakutsogolo wadongosolo. Izi zitha kupangitsa kuti kulumikizana kwa AC kusakhale ndi ndalama zambiri kwa ogwiritsa ntchito ena, makamaka poyerekeza ndi zomangira zosavuta zama grid.
Kutayika Kwachangu: Kuphatikizika kwa AC kumatha kuyambitsa kutayika kwachangu poyerekeza ndi kuphatikiza kwachindunji kwa DC kapena zomangira zama grid. Njira zosinthira mphamvu pakati pa AC ndi DC, komanso kuyitanitsa ndi kutulutsa batire, zimatha kutha mphamvu pakapita nthawi.
Kutulutsa Kwamagetsi Ochepa: Ma inverter a Off-grid ndi mabanki a batri nthawi zambiri amakhala ndi mphamvu zochepa poyerekeza ndi ma inverter omangidwa ndi grid. Kuchepetsa uku kungathe kulepheretsa mphamvu zonse za dongosolo, kusokoneza mphamvu yake yothandizira ntchito zofunidwa kwambiri kapena katundu wokulirapo.
Nkhani Zogwirizana: Kuwonetsetsa kugwirizana pakati pa zigawo zomangidwa ndi gridi ndi zopanda grid kungakhale kovuta. Kusagwirizana kapena kusagwirizana kwamagetsi, ma frequency, kapena ma protocol a kulumikizana kungayambitse kusakwanira kwadongosolo kapena kulephera.
Zolepheretsa Zowongolera ndi Zololeza: Makina olumikizirana a AC atha kukumana ndi zofunikira zowongolera ndi zololeza poyerekeza ndi makonzedwe amtundu wa gridi. Kutsatira ma code am'deralo ndi malamulo oyendetsera makhazikitsidwe a gridi kungapangitse zovuta komanso nthawi ku polojekiti.
Ngakhale pali zovuta izi, kuphatikiza kwa AC kumatha kukhala njira yabwino kwa ogwiritsa ntchito omwe akufuna kulimba mtima, kudziyimira pawokha mphamvu, komanso kusinthasintha pamakina awo amagetsi. Kukonzekera mosamala, kukhazikitsa koyenera, ndi kukonza kosalekeza ndikofunikira kuti muchepetse zovuta zomwe zingachitike ndikukulitsa phindu la kulumikizana kwa AC.
