Peb lub hauv paus tseem ceeb rau xaiv hnub ci PV Transformers: Peev Xwm, Voltage, Zog Efficiency

NtawmHenan GNEE Electric Co., Ltd., peb tau muab ntau txhiab lub hnub ci PV transformers rau cov haujlwm thoob plaws Europe, North America, Southeast Asia, thiab Middle East. Nrog 18+ xyoo ntawm kev tsim khoom thiab tag nrho IEC / CE / UL ntawv pov thawj, peb pab installers, EPCs, thiab distributors xaiv lub transformer txoj cai rau txhua megawatt.

 

Hauv phau ntawv qhia no, peb rhuav tshem covPeb lub hauv paus tseem ceeb rau kev xaiv hnub ci PV transformers- yog li koj tuaj yeem zam qhov tsis sib xws thiab ua kom tiav 25-xyoo txoj haujlwm rov qab los.

 

 

Txoj cai golden ntawm hnub ci PV transformer muaj peev xwm xaiv yog ncaj nraim:loj lub transformer ntawm 1.2 mus rau 1.5 npaug ntawm tag nrho cov kev cob cog rua load.

 

Cov npoo no tuav ob qhov tseeb ntawm kev tsim hluav taws xob photovoltaic - tam sim ntawd huab-ntug irradiance spikes thiab inverter momentary overloads. Qhov zoo tshaj plaws kev nyab xeeb margin yog120%–130%ntawm tag nrho AC tso zis zog. Qhov ntau yam no tiv thaiv kev ntxhov siab thaum lub hnub ci siab tshaj plaws thaum lub sij hawm zam qhov tsis muaj kev poob qis ntawm ib qho overspec'ed unit.

 

Cov txheej txheem muaj peev xwm tiag tiag hauv ntiaj teb los ntawm qhov project scale

 

Kev lag luam & kev lag luam faib cov haujlwm (500kW - 5MW):
A 1600kVA rau 2500kVApad-mounted lossis skid-mounted transformer feem ntau nyiam. Thaum xam, nco ntsoov tias cov motors (xws li, cua txias kiv cua, trackers) kos5-7 lub sijhawmlawv qhov ntsuas tam sim no thaum pib. Txawm hais tias koj qhov project tsis muaj cov motors loj, tawm hauv chav rau kev loj hlob yav tom ntej.

 

Utility-scale av-mount nroj tsuag (10MW +):
Xaiv3150kVA los yog loj duaunits, thiab txais yuav amulti-transformer parallel configuration. Kev ua haujlwm sib luag faib cov kev ntxhov siab, txhim kho kev rov ua dua (ib chav tuaj yeem muab kev pabcuam thaum lwm tus khiav), thiab txo qhov cuam tshuam. Rau ib tsob nroj 50MW, siv 10 units ntawm 5MVA txhua tus yog qhov kev ntseeg siab tshaj li ob 25MVA dab.

 

 

Voltage mismatch yog ib qho yuam kev kim tshaj plaws hauv kev tsim lub hnub ci project. Koj yuav tsum xaiv lub transformer thawj (daim phiaj) thiab theem nrab (inverter sab) voltagesraws nraim li hauv zos kab lis kev cai thiab inverter specifications.

 

Hom voltage configurations:

Kev lag luam ru tsev / me me kev lag luam (tsawg dua lossis sib npaug rau 6MW):
10 kVthawj voltage yog qhov nruab nrab-voltage interconnection tshaj plaws thoob ntiaj teb. Secondary voltage yog feem ntau400V, 480V, lossis 690V- txuam cov hlua niaj hnub inverters lossis central inverters.

 

Large ground‑mount plants (>10 MW):
35kv ua(los yog 33kV / 34.5kV) thawj qhov hluav taws xob yog tus qauv rau thaj chaw substations. Secondary voltages feem ntau yog los ntawm600V txog 800V, nyob ntawm tus qauv inverter. Rau cov nroj tsuag loj heev, kev hloov pauv ob-kauj ruam (xws li, 690V → 35kV → 110kV) yuav tsum tau.

 

Tsis txhob hnov ​​​​qab txog on-load tap changer (OLTC)

Hnub ci tso zis voltage hloov pauv dav nrog irradiance thiab kub - feem ntau± 5% rau ± 10%nyob ib ncig ntawm tus nqi nominal. Tus qauv off-circuit kais changer (DETC) tuaj yeem hloov kho tsuas yog thaum lub tshuab hloov hluav taws xob de-energised. Yog vim li cas rau daim phiaj-txuas PV, peb xav kom ib tugon-load tap changer (OLTC)los yog tsawg kawg yog qhov dav-ntau yam tsis muaj-load kais hloov pauv nrog tsawg kawg±2×2.5%cov kauj ruam. Qhov no ua kom koj lub inverter ib txwm pom cov khoom siv hluav taws xob ruaj khov, ua kom MPPT kev ua tau zoo.

 

 

Qhov no yog qhov uas ntau tus neeg yuav khoom tso nyiaj rau ntawm lub rooj. Lub hnub ci transformer ua haujlwm24/7/365- txawm tias hmo ntuj, lub hauv paus tseem muaj zog thiab siv tsis muaj qhov poob. Tshaj ib25-xyoo PV cog lub neej, cov "me" poob ntxiv mus txog kaum tawm txhiab daus las.

 

Tshiab GB 20052-2024 tus qauv - koj yuav tsum paub dab tsi

Siv tauLub Ob Hlis 1, 2025, Tuam Tshoj tus tshiab lub teb chaws tus qauvGB 20052-2024Lub zog txuag hluav taws xob txwv thiab qib kev siv hluav taws xob rau cov hluav taws xob hloov hluav taws xob, thawj zaug, systematically suav nrogphotovoltaic, cua zog, thiab lub zog cia transformers. Tus qauv txhais peb lub zog efficiency tiers, nrogTier 1 (NX1)yog qhov siab tshaj plaws - yuav tsum tau qis tshaj tsis muaj load thiab load poob.

 

Rau hnub ci tej yaam num, feem ntau xaiv hnub no yog lubSCB14 los yog SCB18 cast-resin qhuav-hom transformer(los yog roj-immersed S22 / S20 rau hauv av-mount). Piv rau SCB12 tiam dhau los, SCB18 muaj:

• Tsis muaj-load poob los ntawm 15-20% qis dua qhov kev txwv GB tam sim no
• Load poob los ntawm 10-15%

 

 

 

Xaiv qhov raugmuaj peev xwm, hluav taws xob, thiabzog efficiency tiertsis yog tsuas yog kev ua raws cai - nws cuam tshuam ncaj qha rau koj qhov project CAPEX, OPEX, thiab ROI mus sij hawm ntev. Txawm koj xav tau ib1600kVA, 2500kVA, lossis 3150kVA hnub ci skid transformer, lossis ua tiav MV / LV substation rau 50MW av-mount cog,GNEExa lub Hoobkas ncaj qha zoo nrog tag nrho IEC / GB / UL ntawv pov thawj.
