Grid-tie, inozivikanwawo segridi-yakasungwainverterskana utility-interactiveinverters, ita basa rinokosha mukufambisa kubatanidzwa kwesimba rinogadziriswa mumagetsi aripo.Tekinoroji yavo yehunyanzvi inoshandura yakananga ikozvino (DC) inogadzirwa neanogona kudzokororwa masisitimu senge solar panel kana mhepo turbines kuita alternating current (AC) inogona kudzoserwa kugridi.
Iyo yakakosha kushanda musimboti wegridhi-yakasungwainverterinotenderedza kuwiriranisa kwesimba rinogadzirwa ne frequency uye voltage yegridi.Uku kuwiriranisa kwakakosha pakuona jekiseni risina musono resimba rinodzokororwa mugridi, kunyatso shandura dzimba nemabhizinesi kuita zvidyarwa zvemagetsi zvidiki.Ngatitarisei zvakanyanya pamatanho uye zvikamu zvinobatanidzwa mune iyi innovation maitiro.
1. DC ku AC kutendeuka: Nhanho yekutanga yegridi-yakabatanainverterkushanda kushandura simba reDC rinogadzirwa nesimba rinodzokororwa kuita simba reAC.Izvi zvinowanikwa kuburikidza nemaseketi emagetsi anoshandisa high-frequency switching kushandura simba uye kugadzira sine mafungu akafanana negrid frequency.
2. Maximum Power Point Tracking (MPPT): Kune solar photovoltaic systems, MPPT teknolojia inoshandiswa kugadzirisa magetsi emagetsi.Iyo MPPT algorithm inoteedzera iyo yakanyanya simba poindi yemapanera ezuva, kuve nechokwadiinverterinoshanda zvakanyanya kunyangwe pasi pemamiriro ezuva akasiyana.
3. Kuwiriranisa negedhi paramita: Kana simba reDC rashandurwa kuita simba reAC, grid-yakabatana.inverterinowiriranisa frequency uye voltage yeiyo inogadzirwa AC simba neiyo grid paramita.Izvi zvinowanikwa kuburikidza neyepamberi kudzora algorithms inoramba ichitarisa frequency uye voltage yegridi uye kugadzirisa iyoinverterkubuda maererano.
4. Anti-islanding dziviriro: Grid-yakabatanainvertersakashongedzerwa ne-anti-islanding dziviriro nzira yekudzivirira jekiseni remagetsi mugedhi panguva yekukanganisa kwegidhi kana mabasa ekugadzirisa.Matanho aya anotsaurainverterkubva pagridi, dzivirira njodzi dzinogona kuitika senge mhinduro, uye chengetedza kuchengetedzwa kwevashandi vekushandisa.
5. Simba rehutano uye reactive simba rekutonga: Grid-yakabatanainvertersinogona zvakare kuchengetedza kunaka kwesimba nekushingairira kudzora reactive simba, voltage uye harmonics.Ivo vanogona kubaya kana kutora reactive simba kutsiva kushanduka kwemagetsi uye kuwedzera kugadzikana uye kuvimbika kwegridi.
6. Grid feed-in: Kamwe grid-yakasungwainverterinowiriraniswa negedhi uye inova nechokwadi chekutevedzera zvese zvinodiwa zvehunyanzvi, iyo yakashandurwa AC simba inodzoserwa kune grid.Iri simba rinogona kushandiswa nevatengi vepedyo kana kuendeswa kunzvimbo dziri kure kuburikidza neiyo iripo yekufambisa zvivakwa.
Nheyo yekushanda yegridi-yakasungwainvertersinoshandura nzira iyo hurongwa hwesimba remagetsi hunobatanidzwa mugridi.Iyo tekinoroji inogonesa kugashira kugadzikwa kwezuva, mhepo uye mamwe magetsi anodzoreredzwa masosi pamwero, kuderedza kutsamira pamafuta efossil uye kuderedza kuburitswa kwegreenhouse gasi.Uyezve, grid-yakasungwainverterskupa varidzi vedzimba uye mabhizinesi mukana wekuve vatori vechikamu vanoshingaira mukushanduka kwesimba, zvichibatsira kune remangwana rakasvibira uye rakagadzikana.
Muchidimbu, grid-yakasungwainvertersndiwo akakosha link pakati pesimba renewable system uye grid.Yayo inoshanda DC kune AC shanduko, kuwiriranisa negidhi paramita uye anti-islanding dziviriro inovimbisa yakachengeteka uye yakavimbika kubatanidzwa kwesimba rinodzokororwa muzvivakwa zviripo.Sezvo grid-yakabatanainvertertekinoroji inoenderera mberi, shanduko kune yakachena, inogoneka simba nzvimbo yave yechokwadi.
