Hei wāhanga nui o te whakaputa hiko photovoltaic, ko te mahi matua a te inverter ko te huri i te iahiko tika mai i ngā kōwae photovoltaic ki te iahiko tauutuutu. I tēnei wā, ko te inverter noa i runga i te mākete e wehea ana ki te inverter pokapū me te inverter raupapa rōpū, me te inverter tohatoha momo hou.
Te āhua o tana mahi:
· Kaitahuri raupapa: he raupapa o ngā pūtau photovoltaic ki roto i te tāuru DC ngaohiko-tiketike, kātahi ka hurihia ki te putanga AC.
· Ngā kaitahuri whakarara: he maha ngā pūtau photovoltaic e honoa whakarara ana hei whakanui ake i te iahiko katoa, kātahi ka hurihia hei putanga AC.
· Whakawhiti piriti: te whakamahinga o te ara iahiko piriti mō te tahuritanga dc-ki-ac.
· Hurihuri auau-waenga: mā te huri i te tāuru DC ki te AC auau-waenga, ka hurihia i roto i te hurihuri hei whiwhi i te putanga AC e hiahiatia ana.
I runga i te āhua o te ngaru putanga:
· Hurihuri ngaru sine: he ngaru sine parakore te putanga, e tika ana mō ngā whakaritenga kounga hiko o ngā tono teitei ake.
· Hurihuri sinusoidal kua whakarerekētia: ko te ngaru putanga he ngaru sinusoidal kua whakarerekētia, me ētahi wāhanga harmonic kua tapahia mō te nuinga o ngā tono kāinga me ngā tono arumoni.
· Hurihuri ngaru tapawhā: he ngaru tapawhā te āhua o te ngaru putanga, he māmā, he iti hoki te utu, engari ka nui ake ngā harmonika ka puta.
· Te whakawhiti whānui pāorooro (PWM): te whakamahinga o te hangarau PWM auau-teitei hei whakaputa i te ngaru putanga tata-sinusoidal.
I runga i ngā wāhi tono:
· Kaitahuri motuhake: mō ngā pūnaha whakaputa hiko motuhake e kore e uru ki te whatunga hiko matua, pērā i te rama, te pūtake hiko, me ētahi atu.
· Te kaitahuri hiko o te rā: honoa te mana photovoltaic ki te whatunga matua ka werohia te mana nui ki roto i te whatunga ina kore e hiahiatia, ā, ka whiwhi i te mana kore e ranea mai i te whatunga.
· Kaitahuri whatunga iti: ka taea e te pūnaha whatunga iti te whakatutuki i te whatunga me te whakahaere, ka rerekē ngā pūtake hiko (pērā i te rā, te hau, me ētahi atu) me te kawenga e hono ana.
Koinei ētahi o ngā kāwai hurihuri hiko o te rā. He rerekē ngā āhuatanga me ngā āhuatanga e tika ana mō ngā momo hurihuri. Me whiriwhiri te momo hurihuri tika kia rite ki ngā whakaritenga me ngā āhuatanga tono.
He aha te mahi a te inverter solar?:
Ka whakamahia te kaitahuri hiko o te rā hei huri i te iahiko tika (DC) i hangaia e ngā panera photovoltaic (ngā panera solar) hei iahiko tauutuutu (AC). Ka hurihia e ngā panera photovoltaic te rā hei iahiko tika, ā, ka hurihia e te kaitahuri hiko o te rā taua iahiko tika hei iahiko tauutuutu e whakamahia ana e tātou hei whakakaha i ngā whare, i ngā ahumahi me ngā pakihi.
Ko ngā mahi matua a te inverter solar e whai ake nei:
1. Te Huringa Mana: te whakaputanga o te hiko DC ki te hiko AC i roto i te papa rā hei whakatutuki i ngā hiahia o te whatunga hiko. Ko te iahiko hurihuri (AC) te momo hiko e whakamahia ana i roto i te oranga o ia rā me te hanga ahumahi.
2. Hononga-pūnaha: mō ngā pūnaha photovoltaic e hono ana ki te pūnaha hiko, ka taea e te inverter solar te wero i te hiko nui ki roto i te pūnaha hiko hei whakaiti i te whakawhirinaki ki te pūnaha hiko, me te whakaputa i tētahi moni whiwhi ipurangi.
3. Whakahaere hiko: ka taea e te inverter solar te aroturuki me te whakahaere i te pūnaha PV, te aroturuki i te tūnga, te iahiko, te ngaohiko, me ētahi atu o te papa PV i te wā tūturu, kia taea ai e ngā kaiwhakamahi te aroturuki me te arotau i te mahi a ngā pūnaha PV.
4. Ngā Mahi Tiaki: ko te tikanga he tiaki taumaha, he tiaki ara iahiko poto, he tiaki ngaohiko nui, he tiaki ngaohiko iti, me ētahi atu hei whakarite i te mahi haumaru o te pūnaha PV.
I roto i ngā kupu poto, he mea nui te mahi a te inverter solar i roto i ngā pūnaha photovoltaic, e huri ana i te pūngao mārama ki te aukume tauutuutu whai hua, e āhei ai te whakamahi i te pūngao solar mō te tuku hiko me te urunga ki te whatunga hiko, kia tutuki ai ngā whāinga whanaketanga tauwhiro me te tiaki pūngao me te whakaiti i ngā tukunga.
Ko ngā rauemi mata matua o te inverter ko ngā wāhanga e whai ake nei:
1. Pūrere hiko-ārahi: ko te wāhanga matua o te inverter ko te pūrere hiko-ārahi mana, e whakamahi ana i te nuinga o te wā i te Power Transistor (IGBT) i te Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) rānei. Ka whakamahia ēnei pūrere hei huri i te pūngao hiko mai i te DC ki te AC.
2. Ngā Pūnga me ngā Āraihiko: ka whakamahia hoki ngā pūnga me ngā āraihiko i roto i ngā pūwhakahuri hei penapena me te tātari i te pūngao hiko. Ka whakangawarihia e ngā pūnga te ngaohiko me te iahiko putanga, ko ngā āraihiko ia ka tātari i te haruru auau teitei me ngā harmonika.
3. Rauemi totohu wera me te totohu wera: Ka nui te wera e puta mai i te Pūrere Hiko i roto i te hurihuri, me whakamahi rauemi totohu wera me te totohu wera hei whakaiti i te pāmahana, hei whakarite kia mahi noa te pūrere. Ko ngā whakamahana he mea hanga ki te konumohe, ki te parahi rānei hei whakarato i te wāhi whakamatao e tika ana.
4. PCB (Papa Arahiko Tā): Ko te PCB te kaikawe mō te tāutanga me te hononga o ngā wāhanga hiko i roto i te inverter, he pai te kawe hiko me te kaha ā-pūkaha. Ka hangai te hoahoa ara iahiko inverter ki ngā whakaritenga mana me te tahora ara iahiko mō ngā waea me te hononga e rite ana.
5. Ngā wāhanga hiko me ngā wāhanga ara iahiko: me whakamahi hoki te kaitahuri i ngā momo wāhanga ara iahiko, pērā i ngā taio, ngā ātete, ngā whakawhiti hiko, ngā fiusi, ngā hononga, me ētahi atu mō te whakahaere ara iahiko, te tiaki me te hononga.
Hei tāpiritanga, ko te anga o te inverter he mea hanga i ngā rauemi whakarewa, pērā i te koranu konumohe, te pereti maitai rānei, e whakamahia ana hei whakarato i te tiaki miihini pai me te mahi whakamarara wera.
Koinei ngā rauemi matua o te inverter, he mea nui te mahi a ēnei rauemi i roto i te hoahoa me te hanga o te inverter hei whakarite i te mahi me te pono o te inverter.
