Kaitahuri hiko photovoltaic waho-whatunga

Whakataki Hua
Ko te kaitahuri hiko PV waho-whatunga he taputapu huri hiko e pana-tōia ana, e whakanui ana i te mana DC whakauru, kātahi ka hurihia hei mana AC 220V mā te hangarau whakarerekētanga whānui pāorooro SPWM o te piriti kaitahuri.
Pērā i ngā kaitahuri hono-pūnaha, me nui te pai o te mahi, te pono, me te whānuitanga o te ngaohiko tāuru DC e hiahiatia ana e ngā kaitahuri PV kore-pūnaha; i roto i ngā pūnaha hiko PV kaha-waenga me te kaha-nui, me puta te ngaru sinusoidal me te iti o te hē.

Te Mahi me ngā Āhuatanga
1. Ka whakamahia te pūmana iti 16-moka, te pūtukatuka iti DSP 32-moka rānei hei whakahaere.
2. Aratau whakahaere PWM, ka tino whakapai ake i te whai huatanga.
3．Whakamahia te mamati, te LCD rānei hei whakaatu i ngā tawhā mahi rerekē, ā, ka taea te whakatakoto i ngā tawhā e tika ana.
4. Ngaru tapawhā, ngaru whakarerekētia, putanga ngaru sine. Putanga ngaru sine, ko te tere whakapōturi o te āhua ngaru he iti iho i te 5%.
5. Te tika o te whakapūmautanga o te ngaohiko teitei, i raro i te kawenga whakatauranga, ko te tika o te putanga he iti iho i te tāpiri, te tango rānei i te 3%.
6. Mahi tīmatanga puhoi hei karo i te pānga nui o te iahiko ki te pākahiko me te kawenga.
7. He wehewehe te whakawhiti auau teitei, he iti te rahi, he mama hoki.
8. He rite rawa ki te atanga whakawhitiwhiti RS232/485 paerewa, he watea mō te whakahaere whakawhitiwhiti mamao.

10, Me te tiaki hononga whakamuri tāuru, te tiaki ngaohiko iti tāuru, te tiaki ngaohiko nui tāuru, te tiaki ngaohiko nui putanga, te tiaki taumaha putanga, te tiaki ara iahiko poto putanga, te tiaki wera rawa me ētahi atu mahi tiaki.

Ngā tawhā hangarau nui o ngā kaitahuri kore-whatunga
I te wā e whiriwhiri ana i tētahi kaitahuri hiko kore-whatunga, i tua atu i te aro ki te āhua o te putanga me te momo wehewehe o te kaitahuri hiko, he maha ngā tawhā hangarau he mea tino nui anō hoki, pērā i te ngaohiko pūnaha, te mana putanga, te mana tihi, te pai o te tahuritanga, te wā whakawhiti, me ētahi atu. He nui te pānga o te whiriwhiringa o ēnei tawhā ki te hiahia hiko o te kawenga.
1) Ngaohiko pūnaha:
Ko te ngaohiko o te kete pākahiko. He rite tonu te ngaohiko tāuru o te kaitahuri kore-whatunga me te ngaohiko putanga o te kaiwhakahaere, nō reira i te wā e hoahoa ana, e whiriwhiri ana hoki i te tauira, kia tupato kia rite tonu ki te kaiwhakahaere.
2) Mana whakaputa:
E rua ngā momo o te mana whakaputa o te inverter waho-whatunga, ko tētahi ko te mana kitea, ko te waeine ko te VA, koinei te tohu UPS tohutoro, me whakarea hoki te mana hohe putanga tuturu i te tauwehe mana, pērā i te inverter waho-whatunga 500VA, ko te tauwehe mana ko te 0.8, ko te mana hohe putanga tuturu ko te 400W, arā, ka taea te taraiwa i te kawenga ātete 400W, pērā i ngā rama hiko, ngā oumu whakapūmau, me ētahi atu; ko te tuarua ko te mana hohe, ko te waeine ko te W, pērā i te inverter waho-whatunga 5000W, ko te mana hohe putanga tuturu ko te 5000W.
3) Te mana tino teitei:
I roto i te pūnaha PV waho-whatunga, ko ngā kōwae, ngā pākahiko, ngā inverters, ngā kawenga te pūnaha hiko, ko te mana putanga inverter, ka whakatauhia e te kawenga, ko ētahi kawenga whakauru, pērā i ngā hauhautanga, ngā papu, me ētahi atu, ko te mana tīmatanga o te motuka kei roto he 3-5 ngā wā o te mana kua whakatauria, nō reira he whakaritenga motuhake mō te taumaha o te inverter waho-whatunga. Ko te mana tihi ko te kaha taumaha o te inverter waho-whatunga.
Ka whakaratohia e te inverter te pūngao tīmatanga ki te kawenga, mai i te pākahiko, i te waeine PV rānei, ā, ko te toenga ka whakaratohia e ngā wāhanga rokiroki pūngao i roto i te inverter – arā, ngā pūngao me ngā inductors. He wāhanga rokiroki pūngao ngā pūngao me ngā inductors, engari ko te rerekētanga ko te penapena pūngao hiko e ngā pūngao i roto i te āhua o te mara hiko, ā, ko te nui ake o te kaha o te pūngao, ka nui ake te mana ka taea e ia te penapena. Ko ngā inductors, i tetahi atu ringa, ka penapena pūngao i roto i te āhua o te mara aukume. Ko te nui ake o te urunga aukume o te matua inductor, ka nui ake te inductors, ā, ka nui ake te pūngao ka taea te penapena.
4) Te whai huatanga o te tahuritanga:
E rua ngā āhuatanga o te whai huatanga o te hurihanga pūnaha kore-whatunga, ko te tuatahi ko te whai huatanga o te mīhini tonu. He uaua te hurihanga hiko o te kaitahuri kore-whatunga, he maha ngā wāhanga e tika ana kia hurihangahia, nō reira he iti ake te whai huatanga whānui i te kaitahuri hono-whatunga, ko te tikanga kei waenganui i te 80-90%, ko te nui ake o te kaha o te mīhini kaitahuri, ko te teitei ake o te whai huatanga o te wehenga auau teitei i te wehenga auau, ko te teitei ake hoki o te whai huatanga o te ngaohiko pūnaha. Tuarua, ko te whai huatanga o te utu me te tukunga o te pākahiko, koinei te momo pākahiko he hononga, ina honoa te whakaputa hiko photovoltaic me te kawenga, ka taea e te photovoltaic te tuku tika i te kawenga ki te whakamahi, me te kore e hiahiatia te hurihanga pākahiko.
5) Te wā whakawhiti:
He pūnaha kore-whatunga me te kawenga, e toru ngā momo PV, pākahiko, me te whaipainga. Ki te kore e ranea te kaha o te pākahiko, ka huri ki te aratau whaipainga, ka whai wā whakawhiti. Ko ētahi kaitahuri kore-whatunga ka whakamahi i te whakawhiti hiko, ā, ko te wā i roto i te 10 mirihekona, kāore ngā rorohiko papamahi e kati, kāore hoki ngā rama e kimo. Ko ētahi kaitahuri kore-whatunga ka whakamahi i te whakawhiti whakawhiti, ā, ka neke atu i te 20 mirihekona te roa, ā, ka kati, ka tīmata anō rānei te rorohiko papamahi.
