Kodi inverter yolumikizidwa ndi gridi imakwanitsa bwanji kuyenda mu gridi?

Ma inverters ndi ofunikira kwambiri pamakina amakono amagetsi, makamaka pamakina opangira mphamvu zongowonjezwdwa. Ntchito yaikulu ya inverter ndi kutembenuza panopa mwachindunji kwaiye gwero la mphamvu DC monga photovoltaic gulu, mafuta cell, kapena lithiamu batire kuti alternating panopa n'zogwirizana ndi gululi ndi kulumikiza ku gululi.Momwe kuzindikira otaya panopa mu gululi wakhala vuto kuti anthu ambiri ndi nkhawa mu ndondomekoyi.The kuthekera kusiyana, kuthekera kusiyana, ndi mfundo ntchito ya gululi kulumikizidwa bwino kuyankha funso la inverta kuyankha funsoli kuyankha funso lofufuzidwa bwino ndi kuyankha funsoli kuyankha funsoli kuyankha funsoli. ma inverters, ma cell amafuta, kapena mabatire a lithiamu, komanso ntchito yochepetsera yaposachedwa ya inverter.

1. Kodi inverter yolumikizidwa ndi gridi imakwaniritsa bwanji kuyenda kwa gridiyi?

Ntchito yofunikira ya inverter yolumikizidwa ndi gridi imaphatikizapo kutembenuza DC kukhala AC ndikuwonetsetsa kuti zotulutsa za AC zitha kudyetsedwa bwino mu grid.Voltage yofananira ndi ma frequency synchronization ndi mfundo zogwirira ntchito za inverter.Volaji ya AC yopangidwa ndi inverter iyenera kusasinthasintha malinga ndi matalikidwe, ma frequency, ndi gawo ndi gridter voliyumu yotuluka pa gridi yamagetsi. ndiye sichingathe kuwongolera kuyenda kwapano mu gridi ndipo ingakhudzenso kukhazikika kwazomwezi.

Mayendedwe apano amatsatira mfundo yayikulu ya kusiyana komwe kungathe kuchitika: pokhapokha ngati pali kusiyana kwa voteji pakati pa mfundo ziwiri pomwe mphamvu yamagetsi imatha kuchoka pamalo pomwe voteji ndi yokwera kupita kumalo komwe magetsi ndi otsika. Mwanjira ina, ma inverters olumikizidwa ndi gululi, zikutanthauza kuti voteji ya AC ya inverter imayenera kusungitsa kusiyana kwina kuchokera kumagetsi a gridi. Magetsi a gridi akakwera kuposa magetsi otulutsa a inverter, magetsiwo sangalowe mu gridi, ndipo inverter imayenera kusintha mphamvu yake yotulutsa kuti iwonetsetse kuti magetsi amatha kulowa mu gridi bwino.

Komanso, imayenera kuyang'anira mafupipafupi ndi gawo la gridi mu nthawi yeniyeni kuti zitsimikizidwe kuti zikugwirizana.Pakali pano pa gridi ndi kutuluka kwaposachedwa kwa inverter ziyenera kusunga mafupipafupi ndi gawo lomwelo, kotero kuti pamene panopa ikuyenda mu gridi, sizingayambitse kusiyana kwa gawo lililonse lomwe limayambitsa kusinthasintha kwa gridi. Chifukwa chake, inverter imawonetsetsa kuti AC yotulutsa imatha kuyenda pang'onopang'ono mu gridi powongolera ma voltage, ma frequency, ndi gawo.

2.Kodi kuthekera kapena kusiyana komwe kungatheke ndikofunikira kuti pakhale kuyenda kwamagetsi mu gridi?
Inde, kuyenda kwa magetsi kumayendetsedwa ndi kusiyana komwe kungakhalepo kapena kusiyana komwe kungakhalepo. Kusiyana komwe kungatheke ndikusiyana pakati pa zomwe zingatheke, ndipo kusiyana kwamagetsi kumatanthauza kusiyana kwa magetsi pakati pa mfundo ziwiri. Pogwiritsa ntchito inverter yolumikizidwa ndi gridi, kusiyana kwamagetsi pakati pa inverter ndi gridi kumatsimikizira komwe kumayendera. Pokhapokha ngati pali kusiyana kosiyana pakati pa magetsi otulutsa magetsi a inverter ndi magetsi a gridi, magetsi amatha kuyenda ku gridi.

3.Kaya cholumikizira cholumikizira gridi cha photovoltaic chingathe kulumikizidwa ndi cell cell kapena lithiamu batire yomwe ikuganiziridwa pansipa kuti izindikire kutulutsa mphamvu kwa gridi:
Photovoltaic grid-connected inverters akhoza kulumikizidwa osati kokha ku photovoltaic panel system komanso ku mitundu ina ya magetsi a DC, monga maselo amafuta kapena mabatire a lithiamu, kuti apange magetsi opangidwa ndi grid.Mfundo yaikulu yogwirira ntchito ndi yofanana: panopa mwachindunji amasinthidwa kukhala alternating panopa yogwirizana ndi gululi kudzera mu inverter.

Mawonekedwe a mafuta a mafuta ndi mabatire a lithiamu ndi ofanana ndi maselo a photovoltaic: onsewa amapereka mphamvu ya DC, koma magetsi awo ndi kutulutsa kwamakono kungakhale kosiyana. Chifukwa chake, magetsi akamalumikizana ndi gululi, inverter imafuna kusinthasintha kokwanira pakusintha ma voliyumu ndi zomwe zikuchitika pano kuti zigwirizane ndendende ndi magetsi, ma frequency, ndi gawo la gridi.

Nthawi zambiri, ma inverters olumikizidwa ndi gridi a photovoltaic amatha kulumikizidwa ndi gridi ndi cell cell ndi lithiamu batire, malinga ngati inverter imatha kutembenuza molunjika kuchokera kumagwero osiyanasiyana amagetsi kupita kumagetsi osinthika omwe ali oyenera gululi ndipo amatha kuthana ndi zovuta za kusinthasintha kwa batire kapena mafuta otulutsa.

4.Pamene magetsi olumikizidwa ndi grid akwaniritsidwa, kodi inverter ingachepetse zomwe zilipo?
Kuchepetsa kwapano ndi ntchito yofunikira ya inverter yolumikizidwa ndi gululi, makamaka popanga magetsi a gridi. The inverter imatha kuyang'anira kuchuluka kwa magetsi ndi magetsi a gridi ndikukwaniritsa malire apano posintha mphamvu yamagetsi.

Ntchito yochepetsera yapano, yoperekedwa mu inverter, imawongolera mkati ndi algorithm m'njira yoti zotulutsa zomwe zimatuluka sizikupitilira zomwe zimaloledwa ndi grid.Mwachitsanzo, kusinthasintha kwamagetsi kapena kusintha kwa katundu kumachitika mkati mwa gridi, inverter imangochepetsa mphamvu zotulutsa kuti zipewe kusinthasintha kosafunikira kwapano ndikusunga kukhazikika kwa gridi.

Mwa kuyankhula kwina, ntchito yochepetsera yomwe inverter ikugwiritsidwa ntchito imawonetsetsa kuti chitetezo ndi kukhazikika kumasungidwa mu gridi yamagetsi ndikulepheretsa mphamvu yowonjezera mphamvu ya gridi kapena kuwonongeka kwa zipangizo zomwe zingayambe chifukwa cha kutulutsa kwamakono kwa inverter.

Inverter yolumikizidwa ndi gululi imagwira ntchito posintha mphamvu yamagetsi, ma frequency, ndi gawo kuti iwonetsetse kuti ilumikizidwa ndi voteji ya gridi, motero imathandizira kuyenda kwapano mu gridi. Zimatengera kusiyana komwe kungathe kapena kusiyana kwa voteji, ndiye kuti magetsi aziyenda bwino mu gridi; ndiye ngati kusiyana koyenera kulipo pakati pa inverter yotulutsa voteji ndi gridi yamagetsi. panel komanso magwero amagetsi a DC monga ma cell amafuta ndi mabatire a lithiamu.Chifukwa chake, inverter iyenera kukhala yosinthika mokwanira kuti igwirizane ndi kusinthasintha kochokera kuzinthu zosiyanasiyana zamagetsi.Pomaliza, ntchito yochepetsa mphamvu yamagetsi yamagetsi imatha kuletsa bwino kuti gululi likhale lalikulu kwambiri, ndikuwonetsetsa kuti chitetezo ndi kukhazikika kwamagetsi olumikizidwa ndi grid.
