Me yasa maganin samar da wutar lantarki ke da mahimmanci?
Ana buƙatar ingantaccen samar da wutar lantarki don wuraren hakar ma'adinai mai nisa, wuraren gine-ginen manyan titina da wuraren shakatawa na tsibiri.
Akwai manyan hanyoyin fasaha guda biyu a halin yanzu: grid-forming ta injin janareta dizal da grid-forming ta tsarin PV-makamashi-ajiya.
Wannan labarin ya kwatanta mafita guda biyu daga nau'i hudu: hanyar fasaha, yanayin da ya dace, farashi da kwanciyar hankali.
Grid-Kafa ta Diesel Generator
Hanyar Fasaha: Diesel janareta tare da tsarin wutar lantarki na AVR, yana ɗaukar goyan bayan wutar lantarki.
Abubuwan da suka dace: Sansanoni na wucin gadi tare da tsawon lokacin gini ƙasa da watanni 6, wuraren da ba su da isasshen hasken rana, ko ayyukan da ke buƙatar wutar lantarki na gaggawa.
Binciken Farashi: Ƙananan farashi na farko (raka'a 30kW: kimanin $4,434-7,390). Kudin aiki na shekara don samar da dizal yana kusa da $65,000 (man dizal + kula). Harkokin sufurin mai yana da wahala a wurare masu nisa, wanda zai iya haifar da karancin man fetur cikin sauki.
Kwanciyar hankali: Don maganin dizal-janeneta: canjin wutar lantarki ≤ ± 5%, saurin mitar ≤ ± 0.2Hz. Lokacin mayar da martani a hankali (5-6s), raunin ƙarfi don jurewa inrush halin yanzu (sau 3-5 na kaya) yayin tashin mota. Ba a samun aikin fara baƙar fata bayan katsewar grid ɗin wuta.
Ƙirƙirar Grid-Ƙara ta Tsarin Ma'ajiya na PV-Makamashi
Hanyar Fasaha: Photovoltaic + baturin lithium-iron-phosphate + kashe-grid PV inverter + microgrid makamashi sarrafa tsarin (EMS). Ana amfani da janareta na diesel ne kawai azaman tushen wutar lantarki.
Abubuwan da suka dace: Sansanonin dogon lokaci tare da lokacin aiki sama da shekara 1, amfani da wutar lantarki yau da kullun sama da 300kWh, wuraren da ke da isassun hasken rana, ko ayyukan da ke ƙarƙashin buƙatun kimantawa na iskar carbon.
Binciken Farashi: Babban zuba jari na farko (20kW PV + 167kWh makamashi-ajiye: kimanin $ 52,000-74,000); Kudin aiki na shekara-shekara $ 35,000. Matsakaicin farashin makamashi shine kawai $0.11-0.16/kWh.
Lokacin da aka haɗa da amfani da dizal na gaggawa, farashin shekara yana kusan $6,207, yana wakiltar rage farashin 90.1%. Lokacin biya yawanci shine shekaru 3-5.
Kwanciyar hankali: Don maganin PV-makamashi-ajiya: Sauyin wutar lantarki ≤ ± 3%, saurin mitar ≤ ± 0.1Hz; Lokacin sauya tushen tushen da yawa ≤10ms. Yana ba da amsa cikin sauri, mafi girman madaidaicin iko da ingantaccen ƙarfin samar da wutar lantarki.
Shawarwari na Zaɓi
Jimlar farashin sama da shekaru 5 cikakken tsawon rayuwa: kimanin. $350,000 don maganin janareta na diesel; kusan $97,000 don PV-makamashi-ma'ajiya-makamashi, tare da 74.2% jimlar rage farashi don zaɓi na PV-makamashi-majiya.
Matsakaicin kasafin kuɗi, ɗan gajeren lokacin aikin, rashin isasshen hasken rana: Zaɓi grid ɗin da aka ƙirƙira da janareta.
Bibiyar tanadin farashi na dogon lokaci, jaddada kariyar muhalli, isasshiyar hasken rana: Zaɓi grid-makamashi-ma'ajiyar wutar lantarki.
Mafi kyawun bayani: Ɗauki "PV-makamashi-ajiya-dizal" yanayin ƙananan-grid. Wutar lantarki da PV ke bayarwa a ranakun rana, ta tanadin makamashi a ranakun gajimare, kuma janareta na dizal ana kunna shi kawai a ƙarƙashin matsanancin yanayi.
Kuna buƙatar ingantaccen hanyar samar da wutar lantarki?
Xuzhou Zm-Besta yana ba da ɗakunan ajiya na PV-makamashi mai ninkawa nau'in akwati.
Da fatan za a tuntuɓe mu don yin magana.
