Hnub Ci & Cua Farm Kauj Ruam -UpHloov pauv: Cov ntsiab lus tseem ceeb koj yuav tsum tau txais txoj cai ua ntej xaj
Yog tias koj yog EPC lossis tus tsim tawm ua haujlwm ntawm hnub ci PV lossis cua ua liaj ua teb xyoo 2026, ntawm no yog qhov tseeb nyuaj uas kuv tau pom ua si ntau zaus:
Koj lub inverter yog nyob rau ntawm -site. Koj cov haujlwm pej xeem tau ua tiav. Tab sis kojGenerator Kauj Ruam -Up (GSU) transformer tseem 9 lub hlis tam sim no -los yog phem dua, nws tuaj txog thiab tsis ua raws li daim phiaj.
Kuv yog Asia Zhang. NtawmTrust In Grid, peb tau raug tsim tawm mus txog 500kV fais fab transformers txij li xyoo 1995. Peb tau muab cov kauj ruam - nce units rau kev siv hluav taws xob -scale renewables thoob plaws North America, Europe, thiab Asia. Thiab kuv tuaj yeem qhia rau koj - feem ntau GSU teeb meem tsis yog los ntawm kev tsim khoom tsis zoo. Lawv tuaj ntawmtau txais cov specs tsis ncaj ncees lawm ntawm kev sib tw theem.
Qhov no tsis yog ib daim ntawv qhia. Hauv qab no yog cov specs kuv muab ob npaug rau - xyuas nrog txhua tus neeg siv hluav taws xob txuas ntxiv ua ntej peb muab daim duab kos.
1. Rated Fais fab - Sib phim rau Inverter Max, Tsis Nruab Nrab
Ib qho yuam kev ntau: qhov loj me ntawm GSU rau qhovnruab nrabPV / cua tso zis. Hnub ci hits ncov irradiance nruab nrab; cua tuaj yeem khiav ntawm daim ntawv teev npe. Kuv feem ntau pom zoo10 MVArau 8 MVA tag nrho cov zis, tshwj xeeb tshaj yog yog tias koj cov khoom siv tso cai luv luv - lub sij hawm overloading.
2. Harmonics & Winding Design
PV inverters tsimharmonic tam sim no. Standard windings tuaj yeem overheat yog tias tsis suav rau. Peb txhawb lub winding thiab qhia meejlow eddy-tam sim no poob conductorsrau loj GSUs.
3. Txias txoj kev - Xav txog lub xaib
Suab puam hnub ci ua liaj ua teb? Koj xav tauONAF (Oil Natural Cua Forced)cua txias nrog oversized radiators. High-qhov siab qhov cua ua liaj ua teb? Qhiaqhov siab them nyiajrau rwb thaiv tsev (BIL) siab tshaj 1,000 meters.
4. Tus Kais Changer - Feem ntau tsim nyog rau kev hloov kho
Vim cov zis txuas ntxiv hloov pauv hloov pauv, ibNtawm -Load Tap Changer (OLTC)yog kuv qhov kev pom zoo ua ntej. Ib qho Off-Circuit Tap Changer (OCTC) yuav tsis kho sai txaus, ua rau koj lub inverter mus rau offline thaum lub sij hawm hloov hluav taws xob.
5. Ua raws li koj tuaj yeem tiv thaiv
Xyuas kom koj tus neeg muag khoom muabthib peb - tog neeg pov thawj hom kev xeem(IEC 60076 / IEEE C57) Tsis muaj kev xav tsis thoob thaum lub zog.
