Kugwiritsa Ntchito Chingwe cha HV DC pa Machitidwe a Mphamvu mu Mapulojekiti a Mphamvu Zobwezerezedwanso

Pamene kusintha kwa dziko lonse lapansi pankhani ya kuchotsa mpweya woipa m'mlengalenga kukuchulukirachulukira, kugwira ntchito bwino kwa magetsi sikunakhale kofunikira kwambiri kuposa kale lonse. Kwa oyang'anira kugula ndi mainjiniya a mapulojekiti, kusankha njira yoyenera yotumizira magetsi ndiko kusiyana pakati pa gridi yamagetsi yopindulitsa kwambiri ndi yomwe ikuvutika ndi kutayika kwa mizere ndi nthawi yokonza. Pakati pa kukonzanso kwa zomangamanga izi paliChingwe cha HV DC cha machitidwe amagetsi.

Makamaka,Chingwe cha DC cha 75kVyakhala njira yabwino kwambiri yopezera mphamvu zamagetsi—kulinganiza mphamvu yotumizira magetsi ambiri komanso ndalama zoyendetsera ntchito komanso kukhazikitsa.

Mu bukuli lofotokoza bwino, tifufuza ntchito zazikulu zachingwe cha 75kV chamagetsi okwera, udindo wake m'mapulojekiti amakono a mphamvu zongowonjezwdwa, ntchito yake yofunika kwambiri mu uinjiniya wapamwamba wamafakitale, ndi zochitika za zaka 5 zomwe zikupanga tsogolo la kutumiza kwa mphamvu yamagetsi yamphamvu kwambiri.

Kodi Chingwe cha 75kV Direct Current ndi chiyani?

Kuti mudziwe zambiri mwachangu:AChingwe cha 75kV cha direct currentndi njira yapadera yolumikizira magetsi yomwe idapangidwa kuti itumize magetsi mwachindunji (DC) pa ma volts 75,000. Mosiyana ndi zingwe zachikhalidwe zosinthira magetsi (AC), zingwe za DC sizili ndi mafunde ochaja amphamvu, zomwe zimawalola kutumiza mphamvu zambiri pamtunda wautali kwambiri popanda kutaya mphamvu zambiri.

Mapindu akuluakulu ndi awa:

• Kutaya kwa ma transmission mpaka 30% kutsika pa mtunda wautali poyerekeza ndi AC.

• Imafuna ma conductor ochepa (nthawi zambiri mipiringidzo iwiri).

• Imathandizira kulumikizana kwa gridi yopanda mgwirizano.

• Choteteza kutentha kwambiri (nthawi zambiri chapamwamba cha XLPE) chomwe chimagwiritsidwa ntchito poteteza malo ovuta kwambiri.

Ntchito Zofunikira mu Mapulojekiti a Mphamvu Zongowonjezedwanso

Kuphatikiza magwero a mphamvu zongowonjezwdwanso mu ma gridi a dziko kumabweretsa vuto lapadera la malo: malo abwino kwambiri opangira minda ya mphepo ndi dzuwa nthawi zambiri samakhala pafupi ndi mizinda yomwe imagwiritsa ntchito mphamvu. Apa ndi pomwechingwe cha DC chamagetsi okwera kwambiri chotumizira mphamvuimakhala yofunika kwambiri.

1. Kuphatikiza Famu ya Mphepo ya M'mphepete mwa Nyanja

Ma turbine amphepo akukankhidwira kutali kunyanja kuti agwire mphepo yamphamvu komanso yokhazikika. Zingwe za AC zachikhalidwe zimataya mphamvu kwambiri pa mtunda wautali wa sitima yapamadzi.Chingwe cha DC cha 75kVImagwira ntchito ngati chingwe chabwino kwambiri chotumizira kunja kwa ma arrays apakati mpaka akulu kwambiri. Imagwiritsa ntchito bwino mphamvu kuchokera ku siteshoni yosinthira magetsi kupita ku gridi yamagetsi yakunja, kuonetsetsa kuti megawattage yayikulu ikufika kwa ogula.

2. Malo Opangira Mphamvu Zamphamvu za Dzuwa Aakulu

Mafamu amagetsi amagetsi amagetsi nthawi zambiri amakhala maekala masauzande ambiri m'chipululu chakutali kapena madera ouma.Chingwe cha HV DC cha machitidwe amagetsi, opanga mapulogalamu amatha kupanga ma gridi akuluakulu a DC omwe amachepetsa kufunikira kwa ma inverter ambiri okwera mtengo a AC/DC omwe amagawidwa pamalo onsewa. Mphamvu imasonkhanitsidwa ndikutumizidwa bwino ku gridi yayikulu, zomwe zimapangitsa kuti phindu la mphamvu ya dzuwa liwonjezeke kwambiri.

3. Machitidwe Osungira Mphamvu ya Mabatire

Popeza mphamvu zongowonjezwdwanso zimakhalapo nthawi ndi nthawi, kusungira mabatire pa gridi ndikofunikira kwambiri. Mabatire amasunga ndi kutulutsa mphamvu yamagetsi mwachindunji.chingwe cha 75kV chamagetsi okweraKulumikiza mabatire akuluakulu mwachindunji ku mizere yotumizira ya DC kumachotsa kutayika kwa kusintha, zomwe zimawonjezera magwiridwe antchito a malo onse osungiramo zinthu.

Chingwe cha 75kV cha Zipangizo Zamakampani ndi Uinjiniya Wamagetsi

Kupatula magetsi, pali kufunika kwakukulu kwa magetsi okhazikika komanso amphamvu kwambiri m'makampani akuluakulu komanso opanga zinthu zamakono.

Kupanga Zinthu Mwanzeru Kwambiri

Chitsanzo chabwino cha izi ndi makampani opanga ma semiconductor. Makampani opanga ma semiconductor a m'badwo wotsatira (zopangidwa ndi nsalu) amadalira zida zodziwika bwino komanso zogwiritsa ntchito mphamvu zambiri, monga makina ojambulira a ultraviolet (EUV). Makina akuluakuluwa amafunikira magetsi okhazikika komanso opanda cholakwika kuti asunge kulondola kwa nanometer.Chingwe cha 75kV cha zida zamafakitalenthawi zambiri imagwiritsidwa ntchito mkati mwa zomangamanga za malo osungiramo zinthu kuti itsike ndikugawa mphamvu ya DC yoyera bwino, yokhala ndi mphamvu zambiri ku mayunitsi amagetsi am'deralo (PSUs) a makina ofunikira awa.

Uinjiniya Wamagetsi Wamphamvu

Mongachingwe chamagetsi champhamvu cha uinjiniya wamagetsi, 75kV rating imagwiritsidwa ntchito nthawi zambiri mu:

• Kukhazikitsa Magetsi pa Njanji:Kupereka mphamvu ya msana ku maukonde a sitima zothamanga kwambiri.

• Ntchito za Migodi:Kuyika makina akuluakulu obowola pansi pa nthaka ndi makina onyamulira katundu komwe malo ndi ochepa komanso kutsika kwa magetsi kuyenera kuchepetsedwa.

• Malo Osungira Deta:Malo osungira deta a Hyperscale akuyang'ana kwambiri ma backbone a DC a voltage apakatikati mpaka okwera kuti achepetse kutayika kwa transformer ndikukweza Mphamvu Yogwiritsa Ntchito Mphamvu Zonse (PUE).
