Mgbanwe Igwe PV Inverter: "Obi Dị Elu" nke Sistemụ Ike Ọhụrụ

N'ọdịdị ike mmeghari ohuru nke na-agbanwe ngwa ngwa, nke dị n'etiti-ruo-Transformer Voltaji Dị Elus apụtala dị ka ihe dị mkpa maka nnyefe ike dị irè. JZP​ (Jiangsu Jucai Power Technology Co., Ltd.), onye ọsụ ụzọ na ngwọta ike dị elu, agbanweela mpaghara a site na iji Photovoltaic Inverter-Integrated Machine Transformers (PIIMTs). Sistemụ ndị a, nke a na-akpọ "obi dị elu" nke gburugburu ebe obibi ike mmeghari ohuru, na-edozi ihe ịma aka dị mkpa na njikọta ike anyanwụ. Isiokwu a na-enyocha ihe ọhụrụ JZP, ọganihu teknụzụ, na mmetụta atụmatụ na mgbanwe ike zuru ụwa ọnụ.

 

1. Ihe Ndị A Ga-eme na Nkà na Ụzụ: Ịkọwapụta Arụmọrụ na Sistemụ Voltaji Dị Elu ruo na Elu

 

Sistemụ anyanwụ ọdịnala na-adabere na inverters na transformers dị iche iche, na-ebute mfu ike (2–3%) na nrụnye dị mgbagwoju anya. PIIMTs nke JZP na-ejikọta ọrụ ndị a n'ime otu obere unit, na-eme ka arụmọrụ dịkwuo mma n'ofe ngwa 10kV–35kV​.

 

Ihe ọhụrụ dị mkpa

 

Nhazi Ọdịdị Ngwakọta: Site na iji semiconductor silicon carbide (SiC) na usoro H-bridge dị iche iche, PIIMTs nke JZP na-enweta arụmọrụ mgbanwe 98.5%, na-arụ ọrụ karịa sistemụ ọdịnala site na 1.2%.

 

Iwu Voltaji Na-agbanwe Agbanwe: Algọridim PWM dị elu na-eme ka mmepụta kwụsiri ike n'okpuru mgbanwe voltaji ntinye ±10%, nke dị oke mkpa maka mpaghara nwere ọnọdụ grid na-adịghị agbanwe agbanwe.

 

Njikwa Okpomọkụ: Ihe ndị na-agbanwe usoro (PCMs) na sistemụ oyi ikuku a manyere na-eme ka ọrụ kwụsie ike n'oge okpomọkụ dị oke njọ (-40°C ruo +65°C), nke a kwadoro na nrụnye ọzara dịka Qinghai Solar Hub nke China.

 

Ọmụmụ Ihe: Usoro SPV-35000​

 

Ihe nlereanya JZP kacha pụta ìhè, SPV-35000, na-ejikọta transformer step-up 35kV yana ọrụ inverter. E tinyere ya n'ugbo anyanwụ nke nwere ike 200MW na Ningxia, o belatara mfu sistemụ niile site na 1.8% ma mụbaa mmepụta ike kwa afọ site na nde 12 kWh.

 

2. Ngwa dị iche iche na gburugburu ebe obibi ike

 

PIIMTs bụ ihe ndị na-enyere aka ime ka ike mmeghari ohuru dị iche iche:

 

1. a) Ikesa Anyanwụ Azụmaahịa

 

N'elu ụlọ ọrụ mmepụta ihe, PIIMTs na-eme ka njikọ grid dị mfe. Dịka ọmụmaatụ, ngwọta PIIMT dị obere nke JZP (dịka ọmụmaatụ, SPV-5000) belatara oge nrụnye site na 40% maka ọrụ 5MW na Kunshan, China, ebe ọ na-edobe

 

1. b) Nkwụsi ike nke Grid

 

PIIMTs na-eme ka ike grid dịkwuo elu site n'ibelata mgbanwe ndị na-agbanwe agbanwe. N'oge okpomọkụ Jiangsu nke afọ 2025, PIIMTs nke JZP gbanwere mmepụta na ihe na-erughị 20ms iji gbochie mgbawa, na-egosi ikike ha nwere ịkwado grid.

 

1. c) Njikọta Nchekwa Ike

 

Site na ijikọ ya na BESS, PIIMTs na-eme ka ịkpụcha elu dị mma. Otu nnwale na Inner Mongolia gosipụtara mbelata 35% na ụgwọ ibu kachasị elu maka ụlọ ọrụ mmepụta ihe.

 

3. Uru asọmpi: Njikọta teknụzụ na gburugburu ebe obibi

 

Ọchịchị JZP sitere na:

 

1. Ntinye ego na nyocha

 

Pasentị iri na abụọ nke ego a na-etinye kwa afọ na R&D.

 

E tinyere akwụkwọ ikike ikike 157, gụnyere ikike ikike 12 dị mkpa, gbasara njikarịcha mkpuchi na nchọpụta nsogbu.

 

2. Njikọta Vertical

 

Ejiri aka ya mepụta isi ígwè silicon dị elu nke na-adịgide adịgide (ụlọ ọrụ Suzhou).

 

Ahịrị mmepụta akpaaka zuru oke na Chuzhou, na-ebelata oge nnyefe ruo ụbọchị 45.

 

3. Mbugharị zuru ụwa ọnụ

 

Mba iri anọ karịrị nke a na-eje ozi site na ebe nlekọta dị na Suzhou, Chuzhou, na US.

 

O nwetara òkè ahịa nke 18% na Middle East (2024), na-enye nkeji 200 maka obere grid NEOM nke Saudi Arabia.

 

4. Usoro Ọdịnihu na Ọhụụ Atụmatụ
5. Njikọta Abụọ Dijitalụ

 

Ikpo okwu nke JZP nke AI na-eduzi (mmalite: 2026) ga-ebu amụma iyi akụkụ ahụ, na-elekwasị anya na mbelata 40% na oge ezumike a na-atụghị anya ya.

 

2. Ndị na-agbanwe agbanwe steeti siri ike (SSTs)

 

Ndị ọhụrụ na-abịa PIIMTs ga-eji GaN semiconductors dochie windings ọla kọpa, na-enweta arụmọrụ 99.5% na ike bidirectional maka sistemụ V2G.

 

3. Mgbasawanye ahịa

 

"Atụmatụ Afọ Ise nke 14" nke China na-enye iwu ka 2025 nweta ike na-abụghị nke fosil pasentị iri abụọ, nke na-eduga ahịa transformer voltaji nke dị n'etiti ruo na elu nke ruru $240B.

 

PIIMTs nke JZP nke dakọtara na nsuso axis abụọ na-eme ka mmepụta ihe dịkwuo mma maka ugbo buru ibu, na-agbaso ebumnuche decarbonization zuru ụwa ọnụ.
