I roto i te tukanga whakarite mō te hanganga o tētahingā teihana utu hiko arumoni, ko te pātai tuatahi me te pātai matua e pā ana ki te tini o ngā hoa ko: "Kia pēhea te rahi o tētahi whakawhiti hiko me whai ahau?" He mea nui tēnei pātai nā te mea he rite ngā whakawhiti hiko pouaka ki te "ngākau" o te puranga utu katoa, e huri ana i te hiko ngaohiko teitei ki te hiko ngaohiko iti e wātea ana kingā puranga utu waka hiko, ā, e pā tika ana tōna kōwhiringa ki te whai huatanga o te whakahaere, te utu tīmatanga me te kaha whakawhanuitanga ā muri ake nei o te teihana utu hiko.
1. Mātāpono taketake: ko te taurite mana te kaupapa matua
Ko te taahiraa tuatahi i roto i te whiriwhiri i tētahi whakawhiti hiko ko te mahi i tētahi taurite mana tika. He tino māmā te arorau taketake:
Tātaihia te tapeketeihana utu waka hikomana: Tāpirihia te mana o ngā teihana utu katoa e whakaaro ana koe ki te tāuta.
Te kaha o te whakawhiti hiko e ōrite ana: Me paku nui ake te kaha o te whakawhiti hiko (wae: kVA) i te mana katoa o teteihana utu hiko(wāhanga: kW) hei waiho i tētahi tawhē me te āputa ārai mō te pūnaha.
2. Ngā take mahi: ngā tikanga tatau ka taea te mārama i roto i te tirohanga kotahi
Me whakamahi tātou i ngā tauira noa e rua hei tatau māu:
Take 1: Hangaia kia 5 ngā puranga utu tere DC 120kW
Tātaitanga mana katoa: 5 waeine × 120kW/waeine = 600kW
Kōwhiringa whakawhiti hiko: I tēnei wā, ko te whiriwhiri i tētahi whakawhiti hiko pouaka 630kVA te mea tino pai, ā, he mea noa. Ka taea e ia te kawe i te kawenga katoa o te 600kW, me te waiho i tētahi tawhiti whaitake hei whakarite i te mahi pumau me te whai hua o ngā taputapu.
Take 2: Hanga 10Ngā puranga utu tere DC 120kW
Tātaitanga mana katoa: 10 ngā waeine × 120kW/waeine = 1200kW
Kōwhiringa Whakawhiti: Mō te mana katoa o te 1200kW, ko te kōwhiringa pai ko te whakawhiti pouaka 1250kVA. Kua whakaritea tēnei whakatakotoranga mō tēnei taumata mana, kia tino tika ai te tuku hiko.
Mā ngā tauira o runga ake nei, ka kitea e koe ehara i te mea he whakaaro noa iho te kōwhiringa o ngā whakawhiti hiko, engari he mārama te arorau pāngarau hei whai.
3. Te whakaaro matatau: te pupuri i te wāhi mō te whanaketanga ā muri ake nei
Ko te whakamahere whakamua i te tīmatanga o te kaupapa he tohu mō te mōhiotanga pakihi. Mena kei te kite koe i te āheinga o te whakawhānui ake i te āpōpōteihana utu waka hiko, me whakaaro koe ki te hoatu i tētahi "mana" kaha ake i te wā e whiriwhiri ana i te "ngākau" i te taahiraa tuatahi.
Rautaki matatau: Whakapai ake i te kaha o te whakawhiti hiko mā te kotahi taumata e ai ki te tahua.
Mō ngā puranga hiko e 5, ki te kore koe e makona ki te 630kVA, ka taea e koe te whakaaro ki te whakapai ake ki tētahi whakawhiti hiko 800kVA.
Mō tētahi pouaka puranga-10, ka taea te whakaaro ki tētahi whakawhiti hiko 1600kVA kaha ake.
He mārama ngā painga o tēnei: ina hiahia koe ki te whakanui ake i te maha ongā puranga utu waka hikoā muri ake nei, kāore he take ki te whakakapi i te whakawhiti hiko, koinei te taputapu matua me te utu nui, ā, ko te whakawhānui noa i te raina he mea ngāwari noa iho, e tino penapena ana i te utu me te wā o te haumitanga tuarua, e āhei ai koeteihana utu waka hikokia kaha te tipu.
Hei whakamutunga, ko te whiriwhiri i te whakawhiti tika mō terihi hikohe tukanga whakatau e whakataurite ana i ngā "hiahia o nāianei" me ngā "whanaketanga ā muri ake nei". He mea nui ngā tataunga kaha tika hei whakarite i te pumau o ngā mahi o nāianei, ko te whakamahere tirohanga whakamua he inihua nui mō te tipu tonu o te ROI.
Mena kei te whakamahere koe i tētahiteihana utukaupapa, ā, kei a koe tonu ngā pātai mō te kōwhiringa o ngā whakawhiti hiko, tēnā whakapā mai. Kei te hiahia mātou ki te whakamahi i ō mātou wheako hangarau ngaio ki te whakarato ki a koe he kōrerorero otinga ritenga kore utu hei āwhina i a koe ki te hanga i tētahi teihana utu whai hua me te kaha tipu!
