Gridi-tayi, yomwe imadziwikanso kuti grid-womangidwama inverterskapena utility-interactivema inverters, zimagwira ntchito yofunika kwambiri pothandizira kuphatikizika kwa mphamvu zowonjezera mu gridi yomwe ilipo.Ukadaulo wawo waukadaulo umasintha bwino magetsi (DC) opangidwa ndi mphamvu zongowonjezwdwanso monga ma solar panels kapena ma turbines amphepo kukhala alternating current (AC) yomwe imatha kubwezeredwa ku gridi.
Mfundo yofunikira yogwiritsira ntchito grid-womangidwainverterzimazungulira ndi kalunzanitsidwe wa mphamvu kwaiye ndi pafupipafupi ndi voteji wa gululi.Kulunzanitsa kumeneku ndikofunikira pakuwonetsetsa kuti kulowetsedwa kwa mphamvu zongowonjezwdwa mu gridi, kusandutsa bwino nyumba ndi mabizinesi kukhala mafakitale ang'onoang'ono amagetsi.Tiyeni tione mwatsatanetsatane masitepe ndi zigawo zomwe zikugwira ntchito yatsopanoyi.
1. Kusintha kwa DC kupita ku AC: Gawo loyamba la gridi yolumikizidwainverterntchito ndikusintha mphamvu ya DC yopangidwa ndi mphamvu zongowonjezwdwa kukhala mphamvu ya AC.Izi zimatheka kudzera mabwalo amagetsi omwe amagwiritsa ntchito ma frequency apamwamba kwambiri kuti asinthe mphamvu ndikupanga mafunde a sine ofanana ndi ma frequency a grid.
2. Maximum Power Point Tracking (MPPT): Kwa machitidwe a dzuwa a photovoltaic, teknoloji ya MPPT imagwiritsidwa ntchito kupititsa patsogolo mphamvu zamagetsi zamagetsi.The MPPT aligorivimu amatsata pazipita mphamvu mphamvu mapanelo dzuwa, kuonetsetsainverterimagwira ntchito bwino kwambiri ngakhale mukamawala mosiyanasiyana.
3. Kuyanjanitsa ndi magawo a gridi: Mphamvu ya DC ikasinthidwa kukhala mphamvu ya AC, gridi yolumikizidwainverterimagwirizanitsa ma frequency ndi ma voliyumu amagetsi opangidwa ndi AC ndi magawo a gridi.Izi zimatheka kudzera mu ma aligorivimu otsogola omwe amawunika mosalekeza ma frequency ndi ma voltage a gridi ndikusinthainverterkutulutsa molingana.
4. Chitetezo chotsutsana ndi chilumba: Cholumikizidwa ndi gridima invertersali ndi njira yodzitetezera yolimbana ndi zisumbu kuti ateteze jekeseni wamagetsi mu gridi panthawi yazovuta kapena kukonza.Miyezo iyi imapatulainverterkuchokera pagululi, pewani zoopsa zomwe zingachitike monga mayankho, ndikuwonetsetsa chitetezo cha ogwira ntchito.
5. Ubwino wa mphamvu ndi mphamvu zogwiritsira ntchito mphamvu: Gridi yolumikizidwama invertersimathanso kusunga mphamvu yamagetsi mwa kuwongolera mphamvu zotakataka, ma voliyumu ndi ma harmonics.Amatha kubaya kapena kuyamwa mphamvu zochitirapo kanthu kuti alipire kusinthasintha kwamagetsi ndikuwongolera kukhazikika ndi kudalirika kwa gululi.
6. Grid feed-in: Pamene gululi-womangidwainverterimalumikizidwa ndi gululi ndikuwonetsetsa kuti ikutsatira zofunikira zonse zaukadaulo, mphamvu yosinthidwa ya AC imabwezeretsedwa ku gridi.Mphamvuzi zitha kugwiritsidwa ntchito ndi ogula apafupi kapena kutumizidwa kumadera akutali kudzera muzinthu zomwe zilipo kale.
Mfundo yogwiritsira ntchito grid-womangidwama invertersimasintha momwe machitidwe amagetsi ongowonjezwdwwdwdwwdwdwwwdwzawo akuphatikizidwa mu gululi.Ukadaulowu umathandizira kutengera mphamvu zoyendera dzuwa, mphepo ndi mphamvu zina zongowonjezwdwa pamlingo waukulu, kuchepetsa kudalira mafuta oyambira pansi komanso kuchepetsa kutulutsa mpweya wowonjezera kutentha.Komanso, grid yomangidwama invertersperekani eni nyumba ndi mabizinesi mwayi wokhala nawo mwachangu pakusintha kwamagetsi, zomwe zimathandizira tsogolo lobiriwira komanso lokhazikika.
Mwachidule, grid-womangidwama invertersNdiwo ulalo waukulu pakati pa machitidwe amphamvu zongowonjezwdwa ndi grid.Kutembenuka kwake koyenera kwa DC kupita ku AC, kulumikizidwa ndi magawo a gridi ndi chitetezo chotsutsana ndi zilumba zimatsimikizira kuphatikiza kotetezeka komanso kodalirika kwa mphamvu zongowonjezwdwa muzinthu zomwe zilipo.Monga grid yolumikizidwainverterteknoloji ikupitirizabe kupita patsogolo, kusintha kwa malo oyeretsera, okhazikika a mphamvu zakhala zikuchitika.
