I te tipu tere o ngā kaupapa hiko hou pēnei i ngā tipu hiko photovoltaic (PV), ngā pūnaha rokiroki hiko, me ngā teihana utu waka hiko (EV), kua piki haere te rongonui o te ia o ngā pūnaha tohatoha hiko "DCization". Heoi, kei te mau tonu te hē o te whiriwhiri: te whakamahi tika i ngā kaiwawao hiko AC i roto i ngā horopaki DC, ka arahi ki ngā tūponotanga haumaru pēnei i te korenga o te pewa me te kore whai hua o te tiaki. I kitea i roto i tētahi take tūturu tetahi teihana rokiroki hiko e pāngia ana e te miriona miriona o ngā mate nā te poto o te ara iahiko i puta mai i ngā kaiwawao hiko kāore i te ōrite. Ahakoa he rite te āhua o te mahi, he rerekē ngā kaiwawao hiko DC me AC i roto i te hoahoa, ngā tawhā hangarau, me ngā horopaki tono. Ka wehewehea e tēnei tuhinga ō rāua rerekētanga matua puta noa i ngā taha e 5 hei whakarato aratohu mahi mō te whiriwhiri kaupapa hiko hou.
Whakataurite Matua: 5 Ngā Ahu hei Mārama ki ngā Kaiwhakamutu Arahiko DC me AC
E whakaatu ana te ripanga e whai ake nei i ngā rerekētanga ā-kanohi o ngā momo e rua, me ngā whakamārama tāpiri hei whakaatu i te hiranga o ngā horopaki pūngao hou:
| Ahu Whakataurite | Pūwhakapakari Arahiko AC | Pūwhakapakari Arahiko DC | Ngā Pānga Matua i roto i ngā Horopaki Pūngao Hou |
| Te Uauatanga o te Ngaro o te Āwhata | He "pūwāhi whakawhiti-kore" te iahiko AC (kotahi i ia 10ms), e āhei ai te whakakorenga ā-pūrere tūturu me te hanganga māmā. | Kāore he pūwāhi whakawhiti-kore i roto i te DC; ka roa ake te noho o ngā pewa me te kaha teitei ake, me ngā tikanga whakamōmona motuhake (hei tauira, te pupuhi aukume, te aukati korehau) | Ka whakanui ake te ngaohiko/au i roto i ngā taha hiko hou (hei tauira, ngā pūnaha rokiroki hiko) i ngā mōrearea pahūtanga pewa me ngā kaiwawao hiko AC, ka whakararu i te haumaru o ngā taputapu. |
| Ngā Āhuatanga Ngaohiko/Au | Ka urutau ki ngā ngaru sine AC; ko ngā ngaohiko whakatauranga he 220V/380V/10kV te nuinga | E pai ana mō te iahiko DC pumau; ngā ngaohiko kua whakatauria tae atu ki te 500V/1000V/1500V (e motuhake ana ki te pūngao hou) me te ātete ki te "pānga whakawhiti" | Ka eke ngā kōwae PV honohono-raupapa ki ngā ngaohiko DC neke atu i te 1000V, ā, ka pakaru te parenga hiko nā te korenga o te kaha ātete ngaohiko o ngā kaiwawao ara iahiko AC. |
| Arorau Tiaki | Arotahi ana ki te tiaki i te taumaha me te arai-poto; ngā ānau takahi i runga i ngā āhuatanga o te kawenga AC | Tāpirihia te "tiakitanga polarity," "tiakitanga rahunga whakawhiti," me te "pehitanga o te iahiko urunga DC" ki te tiakitanga taketake | Ka whakaputahia e ngā pūnaha rokiroki pūngao ngā iahiko DC e tomo mai ana i te wā e utu ana/e tuku ana; kāore he parenga kua whakaritea mō ngā whati hiko AC, ka arahi ki te hinganga teka, ki te rahunga rānei. |
| Hoahoa Hanganga | He rūma tinei pewa māmā; he iti te rahi, he iti hoki te utu | He hoahoa whakakaha mō te whakakorenga pewa + te whakamarumaru; he rahi ake te rahi, he utu nui ake i ngā hoa AC | Ko ngā kaupapa pūngao hou e hiahia ana kia tino haumaru; ko te hanganga motuhake o ngā kaiwawao hiko DC e whakarite ana i te mahi pumau mo te wa roa |
| Te Roa o te Ora me te Tiaki | ~10 tau te roa o te oranga i roto i ngā āhuatanga AC me ngā utu tiaki iti | Te roa o te ora 8-10 tau i roto i ngā horopaki DC; me tirotiro auau i ngā rūma pewa me ngā paerewa tiaki teitei ake | Ko ngā tipu rokiroki PV/pūngao nui e whakatairanga ana i ngā whati ara iahiko DC roa te ora hei whakaiti i te wā kore mahi me ngā utu tiaki. |
Whakamārama Tāpiri:
Ko ngā āhuatanga hiko DC hou (hei tauira, ngā taha aho PV, ngā tautau pākahiko rokiroki hiko, ngā putanga hiko DC rihi EV) he "kāore he pūwāhi whakawhiti-kore, he ngaohiko teitei, he iahiko nui"—ngā āhuatanga kei tua atu i ngā kaha o ngā kaiwhakawā hiko AC ki te whakakore i te pewa me te ātete ngaohiko. Nā tēnei, me whai kaiwhakawā hiko DC motuhake mō ngā tono hiko hou.
Ka whakamahia e ā mātou whati ara iahiko DC hou e motuhake ana ki te pūngao te hangarau whakakore pewa korehau me te hangarau pupuhi aukume (te wā whakakore pewa ≤2ms) me ngā ngaohiko kua whakatauria e kapi ana i te 500V-1500V, ka urutau pai ki ngā āhuatanga utu PV, rokiroki pūngao, me te EV.
Ngā Mātāpono Kōwhiringa Whaihua mō ngā Horopaki Pūngao Hou
1. Maukati te Aronga Matua mā te Momo o NāianeiKo ngā ara iahiko DC (hei tauira, ngā aho PV, ngā kete pākahiko rokiroki hiko, ngā putanga DC rihi) me whakamahi i ngā whati ara iahiko DC; ko ngā ara iahiko AC (hei tauira, ngā putanga inverter, ngā pūwāhi hononga whatunga, ngā koropiko tohatoha ngaohiko iti) me whakamahi i ngā whati ara iahiko AC—kāore e whakaaetia te whakamahi whakauru.
2.Whakatikatikahia te Kōwhiringa mā ngā Tawhā Horopaki:
①Ngā Whare Hiko PV: Whakaritea ngā pūwhakarere hiko DC me te "whakaurunga ngaohiko whānui (500V-1000V) + te tiaki hononga whakamuri."
②Ngā Pūnaha Rokiroki Pūngao: Kōwhiria ngā tauira me te "wātea tere (≤2ms) + te pehi i te aukume tomo" hei karo i ngā tūponotanga o te ara iahiko poto o te pākahiko.
③Ngā Teihana Utu EV: Kōwhiria ngā pūwhakawhiti hiko DC "kiato + tiaki teitei (IP67)" mō te tāutanga o waho.
3. Whakaitihia ngā Mōrearea mā te whakamahi i ngā TiwhiketeKōwhiria ngā hua e tutuki ana i te GB/T 14048.3-2017 (paerewa ā-motu mō te pūngao hiko DC), CE (mō ngā mākete Pākehā), me te UL (mō ngā mākete o Amerika Te Raki) hei whakatutuki i ngā whakaritenga hou mō ngā kaupapa pūngao.
Akoranga Take: Ngā Tūponotanga o te Kōwhiringa Hē me te Uara o te Kōwhiringa Tika
I te tīmatanga, i whakamahia e te tipu hiko PV 100MW ngā pūwā hiko AC i te taha DC hei whakaiti i ngā utu. I puta he ahi i puta mai i te pakaru o te pewa i muri i te 3 marama o te mahi, ā, i puta he mate tika e 2 miriona yuan. Whai muri i te huri ki ngā pūwā hiko DC motuhake, kua mahi pumau te tipu mō ngā tau e 2 me te kore he hapa. Ko tētahi atu kaupapa rokiroki hiko e whakamahi ana i ā mātou pūwā hiko DC 1500V i angitu ki te karo i ngā mōrearea poto-pūhiko e 3 mā te pakaru tere, me te whakaiti i ngā utu tiaki mā te 40% ki te whakataurite ki ngā toharite o te ahumahi. E whakaū ana ēnei take ko te whiriwhiri tika i ngā pūwā hiko ka whakarite i te haumaru me te penapena utu mō te wā roa i roto i ngā āhuatanga hiko hou.
Whakamutunga: Aratohu Huringa + Whakamana Rauemi
Ko te haumaru o te tohatoha hiko i roto i ngā kaupapa pūngao hou ka tīmata mā te whiriwhiri tika i ngā kaiwawao ara iahiko. Hei tohunga ki ngā otinga kaiwawao ara iahiko,NGĀ TANGATAe tuku ana i te whānuitanga katoa o ngā pūwāhi ara iahiko DC mō ngā tono PV, rokiroki pūngao, me te utu EV, e tautoko ana i te hoahoa tawhā kua whakaritea.Tena koa whakapā mai ki ā mātou kaitohutohu hangarau mō te tautoko kōwhiringa kaupapa motuhake kore utu!
