Kedu ka inverter ejikọrọ na grid si enweta eruba ugbu a n'ime grid?

Inverters dị ezigbo mkpa na sistemu ike ọgbara ọhụrụ, ọkachasị na sistemu ume ọhụrụ. Isi ọrụ nke inverter bụ iji tọghata kpọmkwem ugbu a na-emepụta site na isi iyi ike DC dị ka panel fotovoltaic, mmanụ ọkụ ma ọ bụ batrị lithium ka ọ na-agbanwe agbanwe ugbu a na-ejikọta ya na grid na jikọọ ya na grid. Olee otú ịghọta na nke ugbu a eruba n'ime grid aghọwo nsogbu nke ọtụtụ ndị mmadụ na-eche banyere na usoro a. Ihe dị iche iche nwere ike, nwere ike dị iche iche, na onye ọ bụla nke na-arụ ọrụ ụkpụrụ ga-adị mma iji chọpụta ajụjụ a ga-eme ka ọ dị mma, nke nwere ike ịkọwa ya na ụkpụrụ nke na-arụ ọrụ nke ga-enyocha ajụjụ a. grid jikọtara fotovoltaic inverters, mmanụ ọkụ, ma ọ bụ batrị lithium, yana ọrụ mmachi ugbu a nke inverter.

1. N'ụzọ dị aṅaa ka inverter ejikọrọ na grid na-enweta eruba ugbu a na grid?

The okporo-jikọrọ inverter si mkpa ọrụ na-agụnye converting DC n'ime AC na n'ịhụ na mmepụta AC nwere ike na-eri nri were were n'ime grid.Voltage kenha na ugboro synchronization bụ ọrụ ụkpụrụ nke ihe inverter.The AC voltaji eme site inverter kwesịrị ịdị na-agbanwe agbanwe na okwu nke njupụta, ugboro, na-adọ na grid na voltaji na voltaji na AC. grid, mgbe ahụ, ọ nweghị ike ime ka mmiri dị ugbu a banye na grid ma nwee ike imetụta nkwụsi ike nke ikpeazụ.

The eruba nke ugbu a na-agbaso isi ụkpụrụ nke nwere ike dị iche: naanị mgbe e nwere voltaji dị iche n'etiti ihe abụọ nwere ike ugbu a eruba si ebe voltaji dị elu na ebe nke ugbu a bụ low. N'ikwu ya n'ụzọ ọzọ, n'ihi na grid-jikọrọ inverters, ọ pụtara mmepụta AC voltaji nke inverter kwesịrị ịnọgide na-a ụfọdụ nwere ike dị iche site na grid voltaji.Specifically, mgbe mmepụta bụ voltaji nke ugbu a na voltaji na griter ga-eruba n'ime voltaji nke ugbu a karịa inverter. okporo; Mgbe grid voltaji dị elu karịa mmepụta voltaji nke inverter, ugbu a agaghị eruba n'ime grid, na inverter kwesịrị ịgbanwe ya mmepụta voltaji iji hụ na ugbu a nwere ike ịbanye na okporo were were.

Ọzọkwa, ọ ghaghị ịgbaso ugboro ole na oge nke grid na oge iji hụ na mmekọrịta. Ihe dị ugbu a nke grid na mmepụta nke ugbu a nke inverter kwesịrị idobe otu ugboro na oge, nke mere na mgbe ugbu a na-abanye n'ime grid, ọ gaghị eme ka ihe ọ bụla dị iche iche na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe mgbagwoju anya. Ya mere, onye ntụgharị ahụ na-ahụ na mmepụta AC nwere ike ịbanye na grid site na ịhazi voltaji, ugboro na oge.

2.Inwere ike ma ọ bụ ihe dị iche iche dị mkpa iji mepụta ntinye nke ugbu a n'ime grid?
Ee, ọkụ eletrik na-ebute n'ụzọ bụ isi site n'iche nwere ike ime ma ọ bụ ihe dị iche. Ọdịiche nwere ike ime bụ ọdịiche dị n'etiti ike abụọ, na ọdịiche voltaji pụtara ọdịiche voltaji n'etiti isi ihe abụọ. N'ime ngwa nke inverter jikọtara grid, ọdịiche nke voltaji dị n'etiti inverter na grid na-ekpebi ntụziaka nke ugbu a. Naanị mgbe enwere ọdịiche dị n'etiti mmepụta voltaji nke inverter na voltaji grid, nke ugbu a ga-agbaba na grid. Onye ntụgharị ahụ na-ekwe nkwa na ọdịiche voltaji a dị n'ime oke kwesịrị ekwesị site n'ịgbanwe voltaji mmepụta iji mezuo nzube ya nke ikwe ka ọ na-aga ugbu a na grid.

3.Ma fotovoltaic grid-jikọrọ inverter nwere ike jikọọ na mmanụ ụgbọala cell ma ọ bụ lithium batrị chere ebe a n'okpuru ịghọta grid ike ọgbọ:
Enwere ike ijikọ ndị na-atụgharị fotovoltaic grid na-ejikọta ọ bụghị nanị na usoro fotovoltaic panel kamakwa na ụdị ndị ọzọ nke ọkụ ọkụ DC, dị ka mmanụ ọkụ ma ọ bụ batrị lithium, maka grid na-ejikọta ike.

Njirimara mmepụta nke mkpụrụ ndụ mmanụ ọkụ na batrị lithium yiri nke sel fotovoltaic: ha abụọ na-enye ike DC, ma voltaji ha na mmepụta ugbu a nwere ike ịdị iche. N'ikpeazụ, mmepụta voltaji nke mmanụ ụgbọala na-enwe mmetụta dị ukwuu site na mgbanwe nke ibu, na voltaji nke batrị lithium nwere ike gbanwee site na ọnọdụ chaja na ọnọdụ ahụike nke batrị ahụ. Ya mere, mgbe usoro ike ndị a na-ejikọta na grid, onye ntụgharị na-achọ mgbanwe zuru oke n'ịgbanwe voltaji na mmepụta ugbu a ka o wee nwee ike kwekọọ na voltaji, ugboro na oge nke okporo.

N'ikwu okwu n'ozuzu, fotovoltaic grid-jikọrọ inverters nwere ike jikọọ na grid na mmanụ ụgbọala na batrị lithium batrị, ma ọ bụrụhaala na onye ntụgharị ahụ nwere ike gbanwee kpọmkwem ugbu a site na isi mmalite ike dị iche iche ka ọ bụrụ ihe ọzọ dị ugbu a kwesịrị ekwesị maka grid ma nwee ike ịnagide ihe ịma aka nke mgbanwe na batrị ma ọ bụ mmepụta mmanụ ụgbọala.

4.Mgbe grid-jikọrọ ike ọgbọ na-ghọtara, ike inverter ịgbachi ugbu a?
Mbelata nke ugbu a bụ ọrụ dị mkpa nke onye na-eme ihe na-ejikọta grid, karịsịa na usoro nke mmepụta ike grid.The inverter nwere ike nyochaa ugbu a na voltaji ibu nke grid ma nweta njedebe ugbu a site n'ịgbanwe ike mmepụta.

Ọrụ mmachi nke ugbu a, nyere na inverter, na-achịkwa ya n'ime ime ya na algọridim n'ụzọ dị otú ahụ na mmepụta nke ugbu a adịghị agafe karịa ikike nke grid. Dịka ọmụmaatụ, mgbe mgbanwe voltaji ma ọ bụ mgbanwe mgbanwe na-eme n'ime grid, onye ntụgharị na-akpaghị aka na-ebelata mmepụta ike iji zere mgbanwe na-enweghị isi ugbu a ma nọgide na-enwe nkwụsi ike grid.

N'ikwu ya n'ụzọ ọzọ, ọrụ mmachi dị ugbu a nke ntụgharị ntụgharị na-eme ka nchekwa na nkwụsi ike na-edobe na grid ọkụ ma na-egbochi oke grid ike ma ọ bụ mmebi akụrụngwa nke nwere ike ibute site na oke mmepụta ugbu a nke inverter.

The grid-jikọrọ inverter na-arụ ọrụ site n'ịgbanwe nke mmepụta voltaji, ugboro, na-adọ na-ekwe nkwa na ọ na-synchronized na grid voltaji, n'ihi ya na-enyere eruba nke ugbu a n'ime grid.It na-adabere na ike dị iche ma ọ bụ voltaji dị iche, na ọ bụ mgbe ahụ na nke ugbu a ga-asọ nwayọọ nwayọọ n'ime grid; ya bụ ma ọ bụrụ na ihe kwesịrị ekwesị voltaji dị iche n'etiti inverter mmepụta voltaji na grid voltaji grid nwere ike. ọ bụghị nanị na jikọọ na grid na fotovoltaic panel kamakwa DC ike isi mmalite dị ka mmanụ ụgbọala cell na lithium batrị. Ya mere, inverter ga-eme mgbanwe zuru ezu na-emeso mgbanwe si dị iche iche ike isi mmalite.
