Isigaba sesithathu Solar Inverter Isingeniso

Iyini inverter ye-solar yezigaba ezintathu?

Ii-inverter ye-solar yesigaba ezintathuiwuhlobo lwe-inverter olusetshenziswa ezinhlelweni zamandla elanga ukuguqula ugesi we-DC (wamanje oqondile) okhiqizwe amaphaneli elanga ube ngugesi we-AC (oshintshanayo wamanje) ofanele ukusetshenziswa ezindlini noma emabhizinisini.

Igama"izigaba ezintathu"ibhekisela ohlotsheni lwesistimu kagesi lapho i-inverter isebenza khona.Ohlelweni lwezigaba Ezintathu, kunemigqa emithathu ehlukene noma izigaba ezisulwa komunye nomunye ngamadigri angu-120, okuholela ekusabalaliseni okulinganiselwe nokuphumelelayo kwamandla.

Leziama-invertersngokuvamile asetshenziswa ekufakweni kwe-solar yezentengiso noma kwezimboni lapho amanani amakhulu kagesi ekhiqizwa futhi adliwe.Zenzelwe ukuphatha ama-voltage aphezulu namandla amandla kunama-inverter esigaba esisodwa, okuwenza afanelekele ama-solar array amakhulu.

KanjaniIzigaba ezintathu ze-solar invertersumsebenzi

Nansi incazelo eyenziwe lula yokuthi i-solar enezigaba ezintathuama-invertersumsebenzi:

Ukuguqulwa kwe-DC ukuya ku-AC: Amaphaneli elanga akhiqiza amandla e-DC lapho echayeke elangeni.Lawa mandla e-DC afakwaI-inverter ye-solar yezigaba ezintathu.

Ukulandela ngomkhondo kwe-MPPT: I-inverter yenza i-Maximum Power Point Tracking (MPPT), ethuthukisa ukuphuma kwamandla amaphaneli elanga ngokunquma i-voltage kanye nenhlanganisela yamanje ekhiqiza amandla aphezulu okukhipha.

I-Inverter: Amandla e-DC aguqulelwa kumandla e-AC yizingxenye ze-elekthronikhi ezifana nama-IGBT (I-Insulated Gate Bipolar Transistors) noma ama-MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistors).

Ukuvumelanisa igridi: Thei-inverterihlale iqapha i-voltage yegridi kanye nemvamisa ukuze kuqinisekiswe ukuvumelanisa negridi yokusetshenziswa.

Ukulawula amandla: Ii-inverterilungisa ukuphuma kwamandla ngokusekelwe ezidingweni zomthwalo kagesi namandla atholakalayo elanga.

Ukuxhumana kwegridi nokuqapha: IIsigaba sesithathu solar inverterixhunywe kugridi yokusetshenziswa, okuvumela amandla engeziwe ukuthi athunyelwe kugridi noma athathwe kugridi uma kudingeka.

Izici zokuvikela nokuphepha: I-solar enezigaba ezintathuama-invertersahlome ngezindlela ezihlukahlukene zokuvikela, okuhlanganisa ukuvikela ngokumelene nesiqhingi, ukuvikelwa kwe-overvoltage kanye nokuvikelwa kwe-undervoltage.

Izici ezithuthukile zeIsigaba sesithathu solar inverter

1. Okokufaka kwe-MPPT Okuningi: OkuningiAma-inverters ezigaba ezintathuinikeza okokufaka okuningi kwe-Maximum Power Point Tracking (MPPT), okuvumela ukuxhunywa kwezintambo eziningi zamaphaneli elanga anomumo ohlukile noma izimo zomthunzi.

2. Ukulawula amandla asebenzayo: OkunyeAma-inverters ezigaba ezintathunikeza ukulawula kwamandla asebenzayo okuthuthukile.Lesi sici sivumela i-inverter ukuthi ilawule ngokusebenzayo ukugeleza kwamandla asebenzayo, iqinisekise ukulungiswa kwesici samandla kanye nokuzinza kwegridi.Ivumela ukulawula okungcono nokuhambisana nemithetho yegridi.

3. Ukuvikelwa kokulwa nesiqhingi:Iziguqulienokuvikela okulwa nokusabalala kwesiqhingi kunezici zokuphepha ezithuthukisiwe ezithola izimo zegridi ezingavamile, njengokunqamuka kukagesi, futhi zinqamule ngokuzenzakalelayo isistimu sonozungezilanga kugridi.Lokhu kuvikela izisebenzi zikagesi ezingozini zikagesi ngesikhathi sokulungiswa noma kulungiswa.

4. Ukuqapha nokulawula okukude: Abaningi be-solar enezigaba ezintathuama-invertersbabe namakhono okuxhumana akhelwe ngaphakathi avumela ukuqapha nokulawula okukude kohlelo.

5. Imisebenzi yokusekela igridi: IthuthukileAma-inverters ezigaba ezintathuinganikeza ukwesekwa kwegridi ngokulawula i-voltage kanye nemvamisa.Lokhu kuwusizo ikakhulukazi ezinhlelweni ezixhunywe kugridi, lapho isiguquli singazinzisa khona ukuguquguquka kwamandla kagesi futhi sisize ukulinganisa igridi.

6. Izimiso zokuxhumana zenethiwekhi ezithuthukisiwe: Ngaphezu kokuqapha nokulawula kude, ezinyeAma-inverters ezigaba ezintathuisekela izinqubo zokuxhumana ezithuthukisiwe njenge-Modbus noma i-Ethernet, evumela ukuhlanganiswa okungenamthungo nezinye izinhlelo zokuqapha noma izinkundla zokuphatha amandla.

7. Ukuhlanganiswa Nezinhlelo Zokugcina Amandla: Ngokuthandwa okukhulayo kwezixazululo zokugcina amandla, ezinyeEzintathuisigaba solar invertersnikeza izinketho zokuhlanganisa zezinhlelo zokugcina ibhethri.
