Hobaneng ha tharollo ea phepelo ea matla kampong e le bohlokoa?
Hoa hlokahala phepelo ea motlakase e sa tsitsang bakeng sa libaka tsa merafo, libaka tsa kaho ea litsela tse kholo le libaka tsa phomolo tsa lihlekehleke.
Hona joale ho na le litsela tse peli tse kholo tsa tekheniki: ho theha grid ka lijenereithara tsa diesel le grid-forming ka PV-energy-storage system.
Sehlooho sena se bapisa litharollo tse peli ho tloha litekanyo tse 'nè: tsela ea theknoloji, maemo a sebetsang, litšenyehelo le botsitso.
Ho theha Grid ka Jenereithara ea Dizeli
Tsela ea Tekheniki: Jenereithara ea diesel e nang le taolo ea motlakase ea AVR, e amohelang ts'ehetso ea motlakase e sa sebetseng.
Maemo a sebetsang: Likampo tsa nakoana tse nang le nako ea kaho e ka tlase ho likhoeli tse 6, libaka tse nang le khanya ea letsatsi e sa lekaneng, kapa merero e hlokang motlakase o potlakileng.
Tlhahlobo ea Litšenyehelo: Theko e tlase ea ho qala (30kW unit: hoo e ka bang $4,434‑7,390). Litsenyehelo tsa selemo tsa ts'ebetso bakeng sa tlhahiso ea diesel li ka ba $65,000 (mafura a diesel + tlhokomelo). Ho thata ho tsamaisa mafura libakeng tse ka thōko, e leng se ka bakang khaello ea mafura habonolo.
Botsitso: Bakeng sa tharollo ea jenereithara ea diesel: ho fetoha ha motlakase ≤ ± 5%, ho fetoha ha maqhubu ≤ ± 0.2Hz. Nako ea ho arabela butle (5-6s), matla a fokolang a ho mamella inrush hajoale (3-5 linako tsa mojaro) nakong ea ho qala koloi. Sesebelisoa sa Black-start ha se fumanehe ka mor'a hore grid ea motlakase e khaohe.
Ho theha Grid ka PV-Energy-Storage System
Tsela ea Tekheniki: Photovoltaic + lithium-iron-phosphate battery + off-grid PV inverter + microgrid energy management system (EMS). Jenereithara ea diesel e sebelisoa feela e le mohloli oa matla a bolokang matla.
Maemo a sebetsang: Likampo tsa nako e telele tse nang le nako ea ts'ebetso ea selemo se le seng, matla a letsatsi le letsatsi a ka holimo ho 300kWh, libaka tse nang le khanya ea letsatsi e lekaneng, kapa merero e itšetlehileng ka litlhoko tsa tlhahlobo ea khabone.
Tlhahlobo ea Litšenyehelo: Matsete a phahameng a qalong (20kW PV + 167kWh polokelo ea matla: hoo e ka bang $52,000‑74,000); litšenyehelo tsa selemo le selemo tsa ho sebetsa $35,000. Theko e lekantsoeng ea matla ke $0.11‑0.16/kWh feela.
Ha ho kenyelletsoa tšebeliso ea diesel ea tšohanyetso, litšenyehelo tsa selemo li ka ba $6,207, e leng ho fokotsa litšenyehelo tsa 90.1%. Nako ea ho khutlisa hangata ke lilemo tse 3-5.
Botsitso: Bakeng sa tharollo ea PV-energy-storage: ho feto-fetoha ha motlakase ≤ ± 3%, ho feto-fetoha ha maqhubu ≤ ± 0.1Hz; nako ea ho fetola mehloli e mengata ≤10ms. E fana ka karabelo e potlakileng, taolo e nepahetseng le boleng bo holimo ba phepelo ea matla.
Litlhahiso tsa Khetho
Kakaretso ea litšenyehelo nakong ea potoloho ea lilemo tse 5: hoo e ka bang. $350,000 bakeng sa tharollo ea jenereithara ea diesel; hoo e ka bang. $97,000 bakeng sa tharollo ea PV-energy-storage, le phokotso ea 74.2% kakaretso ea litšenyehelo bakeng sa khetho ea polokelo ea matla a PV.
Tekanyetso e tiileng, nako e khuts'oane ea projeke, khanya ea letsatsi e sa lekaneng: Khetha grid e entsoeng ka jenereithara ea diesel.
Phehella ho boloka litšenyehelo tsa nako e telele, totobatsa tšireletso ea tikoloho, khanya ea letsatsi e lekaneng: Khetha marang-rang a PV-energy-storage-formed.
Tharollo e nepahetseng: Amohela "PV-energy-storage-diesel" micro-grid mode. Matla a fanoang ke PV matsatsing a letsatsi, ka polokelo ea matla matsatsing a maru, 'me jenereithara ea diesel e sebelisoa feela tlas'a maemo a leholimo a feteletseng.
Na o hloka phepelo ea motlakase ea kampo e ikhethileng?
Xuzhou Zm-Besta e fana ka liphaposi tsa polokelo tsa PV-eneji tse ka phuthoang.
