Ngā Whakawhiti Mīhini Whakauru-Whakauru PV: Te "Ngākau Tino Pai" o ngā Pūnaha Pūngao Hou​

I roto i te whenua e tere whanake ana o te pūngao hou, waenga-ki-Whakawhiti Ngaohiko TeiteiKua puta ake ngā mea hei wāhanga nui mō te tuku hiko whai hua. Ko JZP​ (Jiangsu Jucai Power Technology Co., Ltd.), he paionia i roto i ngā otinga hiko matatau, kua hurihia tēnei mara me āna Photovoltaic Inverter-Integrated Machine Transformers (PIIMTs). Ko ēnei pūnaha, e kiia ana ko te "ngākau whai hua nui" o ngā pūnaha rauropi pūngao hou, e aro ana ki ngā wero nui i roto i te whakaurunga hiko o te rā. Ka tūhuratia e tēnei tuhinga ngā auahatanga a JZP, ngā whanaketanga hangarau, me te pānga rautaki ki te whakawhiti pūngao o te ao.

 

1. Ngā Ahunga Hou Hangarau: Te Whakahou i te Whai Hua i roto i ngā Pūnaha Ngaohiko Waenga-ki-Teitei​

 

Ka whakawhirinaki ngā pūnaha pūngao rā tuku iho ki ngā kaitahuri me ngā whakawhiti hiko motuhake, ka hua ake he ngaronga pūngao (2–3%) me ngā tāutanga uaua. Ka whakauruhia e ngā PIIMT a JZP ēnei mahi ki roto i tētahi waeine kiato kotahi, ka arotau i te mahi puta noa i ngā tono 10kV–35kV.

 

Ngā Auahatanga Matua

 

Hoahoa Āhuatanga Ranu: Mā te whakamahi i ngā haurua-ā-ira silicon carbide (SiC) me ngā hoahoanga H-bridge maha-wāhanga, ka eke ngā PIIMT a JZP ki te 98.5% te pai o te huringa, ka eke ki te 1.2% te pai ake i ngā pūnaha tuku iho.

 

Te Whakahaere Ngaohiko Hihiri: Mā ngā rauropi PWM matatau ka taea te whakaputa pumau i raro i ngā piki me ngā heke o te ngaohiko whakauru ±10%, he mea nui mō ngā rohe he āhua whatunga kore pumau.

 

Whakahaere Wera: Mā ngā rauemi whakarerekē-āhuatanga (PCM) me ngā pūnaha whakamatao hau-kaha ka mau te pumau o te mahi i ngā pāmahana tino kino (-40°C ki te +65°C), ka whakamanahia i roto i ngā whakaurunga koraha pēnei i te Qinghai Solar Hub o Haina.

 

Akoranga Take: Raupapa SPV-35000

 

Ko te tauira matua a JZP, te SPV-35000, e whakauru ana i tētahi whakawhiti hiko 35kV me ngā mahi whakawhiti hiko. I whakatinanahia ki tētahi pāmu hiko pūngao 200MW i Ningxia, i whakaitihia e ia ngā mate pūnaha katoa mā te 1.8% me te whakapiki ake i te hua pūngao ā-tau mā te 12 miriona kWh.

 

2. Ngā tono puta noa i ngā pūnaha rauropi pūngao

 

He maha ngā āhuatanga o ngā PIIMT hei whakahohe i te whakaurunga o te pūngao hou:

 

1. a) Te Pūngao Rā Arumoni Tohatoha

 

I roto i ngā tuanui ahumahi, ka whakangawaritia e ngā PIIMT ngā hononga whatunga. Hei tauira, nā ngā otinga PIIMT kiato a JZP (hei tauira, SPV-5000) i whakaiti te wā tāutanga mā te 40% mō tētahi kaupapa 5MW i Kunshan, Haina, me te pupuri tonu i te

 

1. b) Te Pūmautanga o te Whatunga

 

I whakarei ake ngā PIIMT i te pakari o te whatunga hiko mā te whakaiti i ngā rerekētanga. I te tihi o te raumati i Jiangsu i te tau 2025, i whakatikatikahia e ngā PIIMT a JZP te putanga ki raro i te 20ms hei ārai i te ngaronga o te hiko, e whakaatu ana i ō rātou kaha tautoko whatunga hiko.

 

1. c) Te Whakaurunga Rokiroki Pūngao

 

Mā te hono atu ki a BESS, ka taea e ngā PIIMT te whakatutuki i te heu tino pai. I whakaatuhia e tētahi whakamātautau i roto i a Mongolia o Roto he whakahekenga 35% i roto i ngā utu kawenga tino pai mō ngā whare hanga.

 

3. Ngā Painga Whakataetae: Te Mahi Tahi o te Hangarau me te Pūnaha Taiao​

 

Ko ngā pūtake o te kaiārahi o JZP:

 

1. Te haumitanga ki te R&D

 

12% o ngā moni whiwhi ka whakahokia ki te R&D i ia tau.

 

157 ngā pateni i tukuna, tae atu ki ngā pateni matua 12 mō te arotau i te whakamarumaru me te tautuhi hapa.

 

2. Whakaurunga Poutū

 

Ngā matua maitai silicon uruhanga-teitei kua whakawhanakehia e ia anō (te wheketere o Suzhou).

 

Ngā raina whakaputa aunoa katoa i Chuzhou, e whakapoto ana i ngā wā tuku ki te 45 rā.

 

3. Te Whakatakotoranga Ao

 

Neke atu i te 40 ngā whenua i tukuna ratonga mā roto i ngā pokapū i Suzhou, Chuzhou, me te US.

 

I hopukina e ia te 18% o te mākete i te Middle East (2024), ā, i tukuna e ia he 200 waeine mō te whatunga hiko iti NEOM o Saudi Arabia.

 

4. Ngā Auahatanga o te Ao me te Tirohanga Rautaki​
5. Whakaurunga Mahanga Mamati

 

Mā te tūāpapa hangarau-a-ringa a JZP (whakarewatanga: 2026) ka matapaetia te pakaru o ngā wāhanga, me te whai kia whakaitihia te wā kore mahi i whakaritea mā te 40%.

 

2. Ngā Whakawhiti Āhua-Toka (SST)​

 

Ka whakakapia ngā takai parahi e ngā PIIMT o te whakatipuranga e whai ake nei ki ngā haurua-ā-ira GaN, ka eke ki te 99.5% te pai o te mahi me te rere hiko e rua-ara mō ngā pūnaha V2G.

 

3. Te Whanuitanga o te Mākete

 

E whakahau ana te "Mahere Tau Rima 14" a Haina kia 20% te whakamahinga o te pūngao kore-pūmua i te tau 2025, kia eke ai ki te mākete whakawhiti hiko waenga-ki-teitei, e $240 piriona te uara.

 

Mā ngā PIIMT hototahi-tuaka-rua a JZP e arotau ana i te hua mō ngā pāmu nui, e hangai ana ki ngā whāinga whakakore waro o te ao.
