He aha te Whakawhiti Whakatikatika Whakaputa Hauwai?

He taputapu hiko motuhake te Whakawhiti Whakarerekētanga Hanga Hauwai e tino hira ana ki te whakaputa hauwai hikohiko, hei pou tuara mō ngā pūnaha whakawhiti hiko e huri ana i te au hiko rerekē (AC) mai i te whatunga hiko, i ngā pūtake pūngao hou rānei ki te au hiko tika (DC) pumau, whakahaeretia e hiahiatia ana mō te hikohiko wai. Ko tana mahi matua he hono i te āputa i waenga i te mana AC ngaohiko teitei me ngā hiahia DC ngaohiko iti, teitei o ngā hikohiko hauwai (hei tauira, ngā hikohiko membrane whakawhiti proton (PEM) rānei), kia pai ai te tuku hiko, kia pono, kia kounga teitei hoki mō te wehewehe i te wai ki te hauwai me te hāora.

Ngā Mahi Matua

E toru ngā mahi matua a te whakawhiti hiko i roto i te hanga hauwai:

Te Huringa Ngaohiko: Ka heke iho i te AC ngaohiko teitei (hei tauira, 10 kV, 35 kV) ki te DC ngaohiko iti (hei tauira, 160 V–592 V) e hiahiatia ana e ngā electrolyzers, e mahi ana i runga i te mana DC hei akiaki i te tauhohenga electrolysis.

Te Whakapūmau i te Mana: Ka whakarato i te whakahaere tika o te ngaohiko me te iahiko hei pupuri i te putanga mana pumau, ahakoa ngā rerekētanga o ngā pūtake pūngao hou (hei tauira, te hau, te rā) me ngā huringa kawenga whatunga. He mea nui tēnei pumau hei ārai i te kino o te electrolyzer me te arotau i te hua hauwai.

Whakaiti i te Hāmoni: Ka whakamahi i ngā hoahoa maha-pā (hei tauira, 12-pā, 24-pā, 48-pā, 96-pā rānei) hei whakaiti i te whakapōturi hāmoni i roto i te ia putanga. Ka taea e ngā hāmoni—ngā auau kāore e hiahiatia i hangaia e te whakatikatika—te whakaiti i te kounga o te mana, te whakanui ake i ngā ngaronga pūngao, me te whakararuraru i ētahi atu taputapu. Ka whakaitihia e ngā āhua maha-pā (e tutukihia ana mā roto i ngā takai nekehanga-wāhanga, ngā piriti whakarara rānei) ēnei whakapōturi, me te tutuki i ngā paerewa pēnei i te IEEE 519.

Ngā Āhuatanga Hangarau Matua

He mea hanga ngā whakawhiti whakatikatika whakaputa hauwai kia tino whai hua, kia pono, kia hototahi hoki ki ngā electrolyzers. He maha ngā āhuatanga matatau kei roto i tō rātou hoahoa:

Ngā Whirihoranga Maha-Pūrere: Ko ngā hoahoa tino noa ko ngā pūnaha 12-pūrere, 24-pūrere, 48-pūrere, tae atu ki ngā pūnaha 96-pūrere. Hei tauira, ka whakamahia e te whakawhiti hiko 96-pūrere (hei tauira, te raupapa ZHSFT a CEEG) ngā piriti whakarara maha me ngā takai nekehanga-wāhanga hei whakaiti i te whakapōturitanga harmonic katoa (THD) ki raro iho i te 10%, hei whakarite i te hototahi whatunga me te tiaki i ngā electrolyzers mai i te ngaru ngaohiko.

Teitei o te Whai Hua: Ka eke ngā whakawhiti hiko hou ki te 97.5% neke atu rānei te whai hua i te kawenga katoa, ka whakaitihia te moumou pūngao. Ka taea tēnei mā ngā rauemi matua iti-ngaronga (hei tauira, te maitai silicon e aro ana ki te witi) me ngā hoahoa takai kua arotauhia.

Te Whakahaere Tika: Ka whakakotahi i ngā whakawhiti tap i runga i te kawenga (OLTC) mō te whakatikatika ngaohiko matotoru (±10% ia taahiraa) me te whakahaere koki-wāhanga thyristor mō te whakatikatika pai (te whakatikatika putanga tonu 0–100%). Ka whakarite tēnei pūnaha ranu i te urutau pai ki ngā whakaritenga tukanga hihiri, pērā i ngā huringa o te kukū electrolyte, te tono whakaputa rānei.

Hanganga Pakari: I hangaia kia tū atu ki ngā āhuatanga mahi uaua (hei tauira, ngā āhuarangi pārūrū, te puehu, te haumākū) me ngā āhuatanga pēnei i te whakamarumaru Akomanga H (ātete ki te 180°C), te whakamatao hinu-ā-kaha (FOA) (mō ngā taiao pāmahana teitei), me ngā ārai ātete-waikura (whakatauranga IP54). Ka roa ake te ora o ēnei āhuatanga (tae atu ki te 30 tau) me te whakaiti i ngā hiahia tiaki.

Te Kaha Utaina Nui: I hangaia hei whakahaere i ngā utaina nui rangitahi (hei tauira, 20% i runga ake i te kaha kua whakatauria) me te kore e whakararu i te mahi, kia kore ai e mutu te mahi i te wā e hiahiatia ana te nuinga o te wā, i ngā piki me ngā heke rānei o te pūngao whakahou.
