Ma ke ʻano he loea kiʻekiʻe manā mea hoʻohui no nā mea hoʻohuli PV, Mālama ʻo Amass i ka mākeke a me nā pono o nā mea kūʻai aku, a hoʻoikaika mau i ka noiʻi huahana a me ka hoʻomohala ʻana a me ka ʻenehana hou. E hoʻomaikaʻi mau i ka pae o ka lawelawe, e hoʻolako i nā mea kūʻai aku me ka maikaʻi, palekana, i hoʻonohonoho pono ʻia i ka lithium-ion hana hoʻohui, i ka ʻoihana Ua hoʻomaikaʻi ʻia mākou i ka ʻoihana.
ʻO ka palapala kaumaha hou "Notice on Encouraging Renewable Energy Power Generation Enterprises to Build or Purchase Peaking Capacity to Increase the Scale of Grid Integration" pono e hoʻonui i ka pālākiō o ka hoʻokomo ʻia ʻana o ka mana hoʻomohala mana hoʻohui.
ʻOiai ʻaʻohe inoa pololei o ka mālama ʻana i ka ikehu, akā ua manaʻo ka mākeke i ka mālama ʻana i ka ikehu ma ke ʻano he mea kūpono.
Ma muli o nā ʻano kūlohelohe kūlohelohe o ka māmā a me ka makani, ka hopena i ka mana hoʻopuka paʻa ʻole, ʻaʻole hiki i ka photovoltaic a me ka mana makani ke hoʻokō mau i nā koi mana o ka pā, ʻo ia hoʻi, haʻalele i ka mālamalama a me ka makani. He ʻōpala maoli kēia. Inā hiki ke mālama ʻia kēia mana hoʻopau ʻia, a laila e emi mau ana ke kumukūʻai o ka hana ʻana i ka ikehu hou. A ʻo kēia hoʻi ke kumu o ka pahū kapikala o ka mālama ʻana i ka ikehu.
Ma hope o ka wehewehe ʻana i ke kuhikuhi ākea, ʻoi aku ka nui o ka ʻimi ʻana i ka māhele me ka ikaika pahū kumu.
Inā mākou e hahai i kēia criterion, a laila ʻo ka inverter ka lima koho hua.
ʻAʻole paʻakikī loa ka manaʻo ma hope o kēia. I loko o ka ʻōnaehana PV, hoʻokani ka mea hoʻohuli i kahi hana koʻikoʻi e like me ka hoʻololi ʻana o AC/DC, ka mana mana, a me ka hoʻololi ʻana i ka parallel/off-grid. A i loko o ka inverter, kona subsidiary'āpana inverter connector hana maikaʻi no hoi pono e hoʻolohe i.
Me ke kōkua ʻole o kahi ʻōnaehana mālama ikehu, pili pono ka uila i hana ʻia e ka PV i ka pā ma o ka inverter. Me ka mālama ʻana i ka ikehu, mālama mua ʻia ka uila i hana ʻia e ka PV i loko o ka ʻōnaehana mālama ma o ka inverter, a laila pili ka uila i ka pā ma o ka inverter. ʻOiai he hoʻokahi manawa hou, akā hiki iā ia ke hoʻopakele i ka uila i haʻalele ʻia (haʻalele ʻia), pēlā e hoʻonui ai i nā hola hoʻohana o PV.
ʻO ka ulu ʻana o ka noi no nā inverters ʻaʻole hiki ke pale ʻia. Wahi a ka wānana o ka noiʻi e pili ana, ʻo ka inverter mālama mālama PV honua e pili ana i ka mana i kau ʻia a hiki i 104GW i 2025, aʻo ka mana i hoʻokomo ʻia i ka honua ma 2020 he 5.3GW wale nō. ʻo ia hoʻi, he 20 mau manawa i loko o 5 mau makahiki, me ka nui o ka ulu ʻana o ka makahiki ma mua o 80%.
E ʻōlelo paha kekahi poʻe, ʻo ka ikehu hou i nā ʻāpana āpau, ke piʻi nei ke koi, no laila ma hea ka nui o ka inverter?
ʻO ka waiho wale ʻana, loaʻa nā inverters i ka logic consumable. ʻO ke ola o kahi mea kanu PV nui i kau ʻia ma ka ʻāina ma kahi o 20 mau makahiki. Hoʻopili ʻia ka inverter e nā ʻāpana uila kūloko (IGBT, capacitors, inductors, etc.), ʻaʻole i ʻoi aku ke ola o ka lawelawe ma mua o 10 mau makahiki. I nā huaʻōlelo ʻē aʻe, kahi mea mana PV
I nā huaʻōlelo ʻē aʻe, pono ka mea kanu PV ma kahi o 2 mau mea hoʻohuli i kona ola. Loaʻa kēia i ka noi inverter e pōmaikaʻi ʻaʻole wale mai ka incremental PV, akā, mai ka waihona. ʻO ka piʻi ʻana o ka noi i lalo e alakaʻi pinepine i ka piʻi ʻana o ke kumukūʻai no nā huahana o luna. ʻO ka mea wale nō, ʻo ka mea nui o ka hoihoi i ka ʻoihana inverter ʻaʻole ka piʻi ʻana o ke kumukūʻai, akā ʻo ke ʻano o ka ʻoihana ma ka ʻaoʻao hoʻolako. ʻO ke kumu ʻaʻole pono ʻoe e nānā i mua i ka piʻi ʻana o ke kumukūʻai, no ka mea, loaʻa i nā inverters nā pale ʻenehana ʻelua, akā no ka spell haʻahaʻa kumu kūʻai. I photovoltaic inverters, no ka laʻana, 1 inverter pili i ka kakini apana o photovoltaic modules, inverters hoʻokahi ka pilikia, e pau ka nenoaiu. Hoʻoikaika i ka palekana, hana ʻia nā inverters mua i Kelemānia. Eia naʻe, e like me ka mea a pau PV oihana kaulahao, inverter o ka haʻahaʻa hoʻokomo paepae, ka loa waiwai-kukui hana o ka loulou, a me keia no hoi e haawi aku i ka hope haʻahaʻa-kumu hoʻohālua.
Inverter pili i ka oi aku mamua o kakini apana o photovoltaic modules, i ka photovoltaic inverter DC terminals he indispensable, i ka manawa like me na ki hoohui 'āpana, i ka manawa o ka maikaʻi o kona mau pilikia, akā, no hoi loa oluolu e alakai i ka lolo o ka. ʻōnaehana mālama ikehu holoʻokoʻa!
ʻO nā mea hana hale ma hope mai poke i ka puka makani ʻenehana, a lawe i ka ʻuhane o ka hana nui, hoʻolaha koke i ka mana hana (hana waiwai waiwai o ka ʻoihana, wikiwiki ka hoʻonui ʻana), me nā huahana maikaʻi a me nā kumu kūʻai haʻahaʻa, e hopu i ka māhele mākeke ma ka ka manawa like, akā, i ka inverter i loko o ka photovoltaic system.Total kumu kūʻai o ka 'ona i emi ma mua o 10%. Ua kūʻai aku nā mea hana hale i nā huahana ʻē aʻe, kikowaena a me ka home inverter unit kumukūʻai o 0.25 yuan / W a me 0.5 yuan / W, haʻahaʻa loa ma mua o nā ʻoihana ʻē aʻe 0.57 yuan / W a me 0.78 yuan / W ke kumu kūʻai kūʻai.
Ma waho aʻe o ka piʻi ʻana o ke kumukūʻai ʻaʻole maikaʻi i ke ʻano ponoʻī o ka ʻoihana, aia ka pilikia o ka hāʻule ʻana me nā mea kūʻai aku. I kēia mau lā, ʻo ka mea ʻino loa i ka kaulahao ʻoihana PV ʻo ia ka mea hana i lalo a me nā mea hana module. ʻO ka mea ʻaʻa e hoʻokiʻekiʻe i nā kumukūʻai, e hui pū lākou i ka hāmare ʻana i ka - piʻi ʻana o ke kumukūʻai akā ua hoʻopaʻa ʻia i ka silikoni, ʻo ke aniani photovoltaic kahi laʻana. Ma keʻano he mea akamai i ke kumukūʻainā mea hoʻopili hoʻopaʻa ikehu, Hoʻohana ʻo Amass i ka mīkini o ka hoʻomohala hui ʻana o nā mea kūʻai aku, e hōʻoiaʻiʻo ana i ka maikaʻi o nā huahana a hoʻemi i ke kumukūʻai i ka manawa like, a mālama i ke kumukūʻai no nā mea kūʻai aku he nui. ʻO ke kūlana maikaʻi loa he kūlana lanakila. ʻO kahi kūlana lanakila-lanakila wale nō e hiki ke hōʻoia i ka hoʻomohala hoʻomau. Ma kēia ʻano, ʻike ʻia kahi ʻano ʻoihana maikaʻi ka moa e waiho ana i nā hua gula ma nā lima o ka ʻoihana inverter.
