Ịghọta Sistemu PV Ejikọtara Grid: Ọrụ nke Inverters na Cables na Igbochite Islanding

1. Gịnị bụ ihe n'àgwàetiti dị na Grid-Tied PV Systems?

Nkọwa

Ihe na-eme n'àgwàetiti ahụ na-eme na sistemu fotovoltaic nke grid (PV) mgbe grid nwetara ọkụ ọkụ, mana usoro PV na-aga n'ihu na-enye ike na ibu ejikọrọ. Nke a na-emepụta "agwaetiti" mpaghara nke nrụpụta ike.

Ihe egwu dị n'àgwàetiti

• Ihe egwu nchekwa: Ihe ize ndụ nye ndị ọrụ ịba uru na-arụkwa grid.
• Mmebi akụrụngwa: Ngwa eletrik nwere ike mebie n'ihi voltaji na-akwụghị ụgwọ na ugboro ole.
• Akwụsịghị grid: Agwaetiti a na-achịkwaghị achịkwa nwere ike ịkpaghasị ọrụ mmekọrịta nke nnukwu grid.

2. MPPT nke ọma (Nsochi ebe ike kacha): Na-ebuli ntụgharị ike site na akụkụ PV.
3. Ịrụ ọrụ ngbanwe dị elu: Na-emekarị>95% iji belata mfu ume.
4. Nkwukọrịta smart: Na-akwado protocol dị ka RS485, Wi-Fi, ma ọ bụ Ethernet maka nlekota.
5. Njikwa anya: Na-enye ohere maka nlekota na njikwa nke usoro remotely.
