Kev nkag siab Grid-Tied PV tshuab: lub luag haujlwm ntawm inverters thiab cables hauv kev tiv thaiv Islands

1. Dab tsi yog cov neeg nyob hauv cov lus tshwm sim hauv daim phiaj-khi PV tshuab?

Zaj piav

Cov kab ke uas muaj kev tshwm sim hauv daim phiaj-khi photovoltaic (PV) thaum muaj lub zog hluav taws xob, tab sis pv system txuas ntxiv rau lub zog sib txuas. Qhov no tsim cov cheeb tsam "kob" ntawm lub zog tiam.

Kev phom sij ntawm Islandsia

• Kev Nyab Xeeb Kev Nyab Xeeb: Muaj feem yuav cov neeg ua haujlwm hluav taws xob kho cov kab sib chaws.
• Cuab Yeej Siv Khoom Puas: Cheebtsam hluav taws xob tuaj yeem ua rau tsis muaj voltage tsis ruaj khov thiab zaus.
• Daim phiaj nyiaj txiag tsis muaj peev xwm: Tswj cov kob tsis tuaj yeem cuam tshuam cov haujlwm synchronized ntawm cov kab sib chaws loj.

2. Cov yam ntxwv tseem ceeb thiab cov tsis muaj qhov tsis raug

Cov yam ntxwv tseem ceeb ntawm inverters

1. Anti-islanding kev tiv thaiv: Siv kev nquag thiab cov kev kuaj mob dhau mus kom cov txheej txheem tam sim ntawd thaum lub sij hawm tsis ua haujlwm.
2. Muaj txiaj ntsig MPT (siab kawg nkaus fais fab tuag): Maximizes Zog Hloov Los Ntawm Pv Panels.
3. Siab hloov zuj zus: Feem ntau> 95% kom txo qis zog poob zog.
4. Ntse Kev Sib Txuas Lus: Txhawb txoj kev cai nyiam Rs485, Wi-nkaus, lossis Ethernet rau kev soj ntsuam.
5. Cov chaw taws teeb tswj: Tso cai rau kev saib xyuas thiab tswj ntawm lub system remotely.

Qhov tseem ceeb ntawm PV cable

Cov Khoom Zoo PV Cables Ua si lub luag haujlwm tseem ceeb hauv kev tswj cov txheej txheem system thiab kom paub tseeb tias cov kab ke muaj tseeb, uas yog qhov tseem ceeb rau kev tiv thaiv kev tawm tsam.

1. Muaj Zog Tiv Thaiv: Txo voltage dauv thiab lub zog poob, ua kom muaj zog ua kom haum rau lub inverter.
2. Daim phiajcim raug: Tsis muaj suab nrov hluav taws xob thiab kev hloov pauv hluav taws xob, txhim kho cov inverter muaj peev xwm los kuaj cov kab sib xyaw.
3. Yam ruaj khov: Saib xyuas kom muaj kev ntseeg tau ntev hauv ntau qhov chaw ib puag ncig, tswj kev ua haujlwm ruaj khov.
