Imikoreshereze ya HV DC Cable kuri sisitemu z'ingufu mu mishinga y'ingufu zisubira

Uko impinduka ku isi yose igana ku gukuraho karuboni mu kirere yihuta, imikorere myiza yo kohereza ingufu ntibyigeze biba ingenzi cyane. Ku bashinzwe amasoko n'abahanga mu mishinga, guhitamo uburyo bukwiye bwo kohereza ingufu ni itandukaniro riri hagati y'umuyoboro w'ingufu winjiza amafaranga menshi n'umuyoboro w'ingufu uhura n'ikibazo cy'imiyoboro y'amashanyarazi n'igihe cyo kutagira aho ubogamira. Imbere muri uku kuvugurura ibikorwa remezo hariInsinga ya HV DC yo gukoresha sisitemu z'ingufu.

By'umwihariko,Insinga ya DC ya 75kVbyagaragaye nk'igisubizo "kiryoshye"—kuringaniza ubushobozi bunini bwo gutanga ingufu z'amashanyarazi hamwe n'ikiguzi cyo kuzishyiraho.

Muri iyi nyandiko yuzuye, tuzasuzuma ikoreshwa ry'ingenzi ryainsinga ifite voltage nyinshi ya 75kV, uruhare rwayo mu mishinga igezweho y’ingufu zishobora kongera gukoreshwa, uruhare rwayo rw’ingenzi mu buhanga buhanitse mu nganda, hamwe n’icyerekezo cy’imyaka 5 kigena ahazaza h’ikwirakwizwa ry’amashanyarazi afite ingufu nyinshi.

Umugozi w'amashanyarazi wa 75kV ni iki?

Kugira ngo ubone amakuru yihuse:AInsinga y'amashanyarazi ya 75kVni umuyoboro w’amashanyarazi wihariye wagenewe kohereza amashanyarazi y’umuvuduko utaziguye (DC) kuri volts 75.000. Bitandukanye n’insinga zisanzwe zisimburana (AC), insinga za DC ntizigira ikibazo cyo gushyushya umuriro, bigatuma zohereza ingufu nyinshi mu ntera ndende cyane kandi nta kiguzi kinini cy’amashanyarazi gihari.

Ibyiza by'ibanze birimo:

• Kugeza kuri 30% by'ibihombo bya transmission mu ntera ndende ugereranije na AC.

• Bisaba ibyuma bitwara amashanyarazi bike (ubusanzwe inkingi ebyiri).

• Bifasha guhuza imiyoboro y'amashanyarazi idahuza.

• Ingufu zikomeye zo gukingira ibidukikije (akenshi zigezweho za XLPE) mu bidukikije bikomeye.

Ikoreshwa ry'ingenzi mu mishinga y'ingufu zisubira

Guhuza amasoko y'ingufu zishobora kongera gukoreshwa mu miyoboro y'amashanyarazi y'igihugu bitanga imbogamizi zidasanzwe mu rwego rw'isi: ahantu heza ho gukorera ubuhinzi bw'umuyaga n'izuba ni gake cyane hafi y'imijyi ikoresha ingufu. Aha nihoInsinga ya DC ifite voltage nyinshi yo kohereza amashanyarazibiba ngombwa cyane.

1. Guhuza ubuhinzi bw'umuyaga mu nyanja

Imashini zikoresha umuyaga zo mu mazi zirimo gusunikwa mu nyanja kugira ngo zifate imiyaga ikomeye kandi ihoraho. Insinga zisanzwe zikoresha AC zitakaza ingufu cyane mu ntera ndende zo mu mazi.Insinga ya DC ya 75kVIkora nk'insinga nziza yo kohereza ibicuruzwa mu mahanga ku buryo buciriritse kugeza ku bunini. Ikoresha neza ingufu kuva kuri sitasiyo y'amashanyarazi yo mu mazi kugera ku muyoboro w'amashanyarazi wo mu mazi, bigatuma megawati nyinshi zigera ku muguzi wa nyuma.

2. Inganda nini zikoresha ingufu z'izuba

Ubuhinzi bw'izuba bukoresha ingufu zikomoka ku mirasire y'izuba akenshi bugera ku bihumbi bya hegitari mu butayu bwa kure cyangwa mu turere twumye.Insinga ya HV DC yo gukoresha sisitemu z'ingufu, abakora umushinga bashobora kubaka imiyoboro minini ya DC igabanya gukenera inverters nyinshi zihenze za AC/DC zikwirakwizwa hirya no hino mu kibanza. Ingufu zihuzwa kandi zoherezwa neza ku muyoboro mukuru, bigatuma inyungu y’umutungo w’izuba izamuka cyane.

3. Sisitemu zo kubika ingufu za batiri

Kubera ko ingufu zishobora kuvugururwa zihoraho, kubika bateri ku gipimo cy'umuyoboro w'amashanyarazi ni ingenzi cyane. Bateri zibika kandi zigasohora umuriro w'amashanyarazi. Gukoreshainsinga ifite voltage nyinshi ya 75kVGuhuza bateri nini cyane ku mirongo ya DC bikuraho igihombo cyo guhindura, byongera imikorere myiza y'ububiko bwose.

Insinga ya 75kV yo gukoresha ibikoresho by'inganda n'amashanyarazi

Uretse amashanyarazi, hari icyifuzo gikomeye cy’ingufu zihamye kandi zifite ubushobozi bwinshi mu nganda zikomeye n’inganda zikora ikoranabuhanga rigezweho.

Inganda zigezweho mu buryo bugezweho

Urugero rw'ingenzi rw'ibi ni inganda zikora ibikoresho bya semiconductor. Inganda zikora ibikoresho bya semiconductor zo mu gisekuru gitaha (fabs) zikoresha ibikoresho byoroshye cyane kandi bikoresha ingufu nyinshi, nka imashini zikoresha ikoranabuhanga rya ultraviolet (EUV). Izi sisitemu nini zikenera ingufu zihamye kandi zitagira inenge kugira ngo zigumane ubuziranenge bwa nanometer.Insinga ya 75kV ikoreshwa mu bikoresho by'ingandaikunze gukoreshwa mu bikorwa remezo bya sitasiyo ntoya z’ikigo kugira ngo ivaneho kandi ikwirakwize ingufu za DC zisukuye neza kandi zifite ingufu nyinshi ku mashanyarazi yo muri izi mashini z’ingenzi (PSUs).

Ubwubatsi bw'amashanyarazi bukomeye

Nk'umuntuinsinga ifite amashanyarazi menshi yo gukora ikoranabuhanga ry'amashanyarazi, amanota ya 75kV akunze gukoreshwa muri:

• Ingufu z'amashanyarazi za gari ya moshi:Gutanga ingufu z'ibanze ku miyoboro ya gari ya moshi yihuta cyane.

• Ibikorwa by'ubucukuzi bw'amabuye y'agaciro:Gukoresha imashini nini ziborera munsi y'ubutaka na sisitemu zo gutwaramo ibintu aho umwanya ari muto kandi amashanyarazi agabanuka bigomba kugabanywa.

• Ibigo by'amakuru:Ibigo by’amakuru bya Hyperscale birimo gushaka cyane imiyoboro ya DC ifite voltage iri hagati kugeza kuri high kugira ngo bigabanye igihombo cya transformer imanuka kandi inoze imikorere myiza y’ingufu (PUE).
