Akụkụ ọrụ aka dị mkpa nke ndị ntụgharị grid kwụsịrị
Mgbe ị na-ahọrọ ihe ntụgharị ọkụ na-apụ apụ, ewezuga ịṅa ntị na mmepụta waveform na ụdị dịpụrụ adịpụ nke onye ntụgharị ahụ, enwere ọtụtụ paramita teknụzụ ndị dịkwa oke mkpa, dị ka voltaji sistemu, ike mmepụta, ike kacha elu, arụmọrụ ntụgharị, oge ngbanwe, wdg Nhọrọ nke paramita ndị a nwere mmetụta dị ukwuu na mkpa ọkụ eletrik nke ibu ahụ.
1) voltaji sistemụ:
Ọ bụ voltaji nke ngwugwu batrị.Ntinye ntinye nke inverter off-grid na voltaji mmepụta nke njikwa bụ otu, ya mere, mgbe ị na-emepụta ma na-ahọrọ ihe nlereanya, ṅaa ntị ka ị na-edebe otu ihe ahụ na njikwa.
2) Ike mmepụta:
Okwu mmeputa ike inverter Off-grid nwere ụdị abụọ, otu bụ ngosipụta ike pụtara ìhè, unit ahụ bụ VA, nke a bụ akara UPS, ikike nrụpụta n'ezie dịkwa mkpa ịbawanye ihe ike, dị ka 500VA off-grid inverter. , ike ihe bụ 0.8, n'ezie mmepụta ike na-arụ ọrụ bụ 400W, ya bụ, nwere ike ịkwanye 400W resistive ibu, dị ka ọkụ eletrik, induction cookers, wdg;nke abụọ bụ okwu ike na-arụ ọrụ, unit bụ W, dị ka 5000W off-grid inverter, n'ezie mmepụta ike arụ ọrụ bụ 5000W.
3) Ike kacha elu:
Na PV off-grid usoro, modul, batrị, inverters, ibu mejupụtara usoro eletriki, ihe inverter mmepụta ike, na-ekpebi ibu, ụfọdụ inductive ibu, dị ka ntụ oyi, nfuli, wdg, moto n'ime, na mmalite ike bụ 3-5 ugboro ike gosiri, ya mere apụ-grid inverter nwere ihe pụrụ iche chọrọ maka ibufe ibu.Ike kacha elu bụ ikike ibufe ihe ngbanwe ikuku-grid.
Onye ntụgharị ahụ na-enye ike mmalite na ibu ahụ, nke sitere na batrị ma ọ bụ modul PV, na oke a na-enye site na ihe nchekwa nchekwa ike n'ime inverter - capacitors na inductors.Capacitors na inductors bụ ma ihe nchekwa nchekwa ike, ma ihe dị iche bụ na ndị na-emepụta ihe na-echekwa ike eletrik n'ụdị eletriki eletrik, na ikike nke capacitor na-ebuwanye ibu, otú ahụ ka ike ya nwere ike ịchekwa.N'aka nke ọzọ, ndị inductors na-echekwa ike n'ụdị oghere magnetik.Ka ikike ndọta dị ukwuu nke isi inductor na-abawanye, ka inductance na-abawanye, na ike ka enwere ike ịchekwa.
4) Ntughari arụmọrụ:
Off-grid usoro ntụgharị arụmọrụ na-agụnye akụkụ abụọ, otu bụ arụmọrụ nke igwe n'onwe ya, sekit inverter na-apụ apụ dị mgbagwoju anya, ịgafe ntugharị multi-stage, ya mere arụmọrụ zuru ezu dị ntakịrị ala karịa ihe ntụgharị njikọ grid, n'ozuzu ya. n'etiti 80-90%, nke ukwuu ike nke inverter igwe arụmọrụ, elu-ugboro iche iche karịa ugboro ikewa arụmọrụ dị elu, elu nke usoro voltaji arụmọrụ dịkwa elu.Nke abụọ, ịrụ ọrụ nke batrị na ịchaji batrị, nke a bụ ụdị batrị nwere njikọ, mgbe fotovoltaic na-emepụta ike na-arụkọ ọrụ ike, fotovoltaic nwere ike ịnye ibu ahụ ozugbo iji mee ihe, na-enweghị mkpa ịgafe ntụgharị batrị.
5) Oge mgbanwe:
Sistemụ grid na-ebu ibu, enwere PV, batrị, akụrụngwa atọ ụdịdị, mgbe ike batrị ezughi oke, gbanwee gaa na ọnọdụ ịba uru, enwere oge ịgbanwee, ụfọdụ ndị na-atụgharị grid na-eji ngbanwe elektrọn, oge n'ime 10 milliseconds, kọmputa desktọpụ agaghị emechi, ọkụ agaghị efegharị.Ụfọdụ ndị na-emegharị ihe na-adịghị grid na-eji ntụgharị relay, oge nwere ike ịbụ ihe karịrị 20 milliseconds, na kọmputa desktọọpụ nwere ike mechie ma ọ bụ malitegharịa.
