Ukusetshenziswa kwekhebula le-HV DC lezinhlelo zamandla kumaphrojekthi wamandla avuselelekayo

Njengoba ushintsho lomhlaba wonke oluya ekususeni igesi eliyingozi lushesha, ukusebenza kahle kokudluliselwa kwamandla akukaze kube yinto ebaluleke kangaka. Kubaphathi bezimpahla kanye nonjiniyela bamaphrojekthi, ukukhetha indlela yokudlulisela efanele umehluko phakathi kwegridi yamandla enenzuzo enkulu kanye negridi yamandla ehlushwa ukulahlekelwa yimigqa kanye nezikhathi zokungasebenzi kahle kokulungiswa. Enkabeni yalokhu kuthuthukiswa kwengqalasizinda kukhonaIkhebula le-HV DC lezinhlelo zamandla.

Ngokuqondile, iIkhebula le-DC elingu-75kVkuvele njengesixazululo "esimnandi"—ukulinganisela amandla amakhulu okulethwa kwamandla kanye nezindleko zokufaka ezilawulekayo.

Kulo mhlahlandlela ophelele, sizohlola izinhlelo zokusebenza eziyinhloko zeikhebula le-75kV elinamandla aphezulu, indima yayo kumaphrojekthi wamandla avuselelekayo esimanje, umsebenzi wayo obalulekile kwezobunjiniyela bezimboni obuthuthukisiwe, kanye nezitayela zeminyaka emi-5 ezibumba ikusasa lokudluliselwa kwamandla kagesi aqondile aphezulu.

Iyini ikhebula lamanje eliqondile elingu-75kV?

Ukuze uthole inkomba esheshayo:AIkhebula lamanje eliqondile elingu-75kViwumsele wamandla okhethekile owenzelwe ukudlulisa ugesi wamanje oqondile (DC) kuma-volts angu-75,000. Ngokungafani nezintambo zamanje ezishintshanayo (AC) zendabuko, izintambo ze-DC azinawo amaza okushaja anamandla, okuvumela ukuthi zidlulise amandla amakhulu amabanga amade kakhulu ngokulahlekelwa amandla okuncane.

Izinzuzo eziyinhloko zifaka:

• Ukulahlekelwa kokudlulisela okuphansi okufika ku-30% emabangeni amade uma kuqhathaniswa ne-AC.

• Kudinga abaqhubi abambalwa (ngokuvamile izigxobo ezimbili).

• Ivumela ukuxhumeka kwegridi okungavumelani.

• Ukuvikela okuqina kakhulu (ngokuvamile i-XLPE ethuthukisiwe) ezindaweni ezibucayi.

Izicelo Eziyinhloko Kumaphrojekthi Amandla Avuselelekayo

Ukuhlanganiswa kwemithombo yamandla avuselelekayo kumagridi kazwelonke kuletha inselele eyingqayizivele yendawo: izindawo ezinhle kakhulu zamapulazi omoya kanye nelanga azivamile ukuba seduze namadolobha asebenzisa ugesi. Yilapho-keikhebula le-DC elinamandla aphezulu lokudlulisa amandlaiba yinto ebaluleke kakhulu.

1. Ukuhlanganiswa Kwepulazi Lomoya Lasogwini

Ama-turbine omoya asogwini lolwandle asunduzelwa olwandle ukuze abambe imimoya enamandla futhi eqhubekayo. Izintambo ze-AC zendabuko zilahlekelwa amandla kakhulu emabangeni amade omkhumbi-ngwenya.Ikhebula le-DC elingu-75kVisebenza njengekhebula lokuthumela elifanele kakhulu lama-array aphakathi kuya kwamakhulu aphesheya kwezilwandle. Ihambisa kahle amandla kusukela esiteshini sokuguqula i-offshore kuya kugridi yaphesheya kwezilwandle, iqinisekisa ukuthi i-megawattage ephezulu ifinyelela kumthengi wokugcina.

2. Izitshalo Ezinkulu Zamandla Elanga

Amapulazi elanga asebenzisa izinsiza avame ukusabalala izinkulungwane zamahektha ezindaweni ezikude zasehlane noma ezomile. Ngokusebenzisa i-Ikhebula le-HV DC lezinhlelo zamandla, abathuthukisi bangakha amagridi amakhulu okuqoqa e-DC anciphisa isidingo sama-inverter amaningi e-AC/DC abizayo asatshalaliswa kuyo yonke indawo. Amandla ahlanganiswa futhi adluliselwe kahle kugridi eyinhloko, okwandisa i-ROI yempahla yelanga.

3. Izinhlelo Zokugcina Amandla Ebhethri

Njengoba amandla avuselelekayo ehlala isikhathi eside, ukugcinwa kwebhethri ngesilinganiso segridi kubalulekile. Amabhethri agcina futhi akhiphe ugesi oqondile ngokwemvelo. Ukusebenzisa i-ikhebula le-75kV elinamandla aphezuluukuxhuma ama-array amakhulu ebhethri ngqo emigqeni yokudlulisa ye-DC kuqeda ukulahlekelwa kokuguqulwa, okwandisa ukusebenza kahle kwendawo yonke yokugcina izinto.

Ikhebula le-75kV Lemishini Yezimboni Nobunjiniyela Bukagesi

Ngale kwegridi kagesi, kunesidingo esikhulu samandla azinzile, anamandla aphezulu embonini esindayo kanye nasekukhiqizweni kobuchwepheshe obuphezulu.

Ukukhiqiza Okunembile Okuthuthukisiwe

Isibonelo esiyinhloko salokhu imboni ye-semiconductor. Izitshalo zokukhiqiza ze-semiconductor zesizukulwane esilandelayo (izindwangu) zithembele emishinini ezwela kakhulu, edinga amandla amaningi, njengemishini ye-photolithography ye-ultraviolet extreme (EUV). Lezi zinhlelo ezinkulu zidinga izinsiza zamandla ezizinzile nezingenaphutha ukuze zilondoloze ukunemba kwezinga le-nanometer.Ikhebula le-75kV lemishini yezimboniivame ukusetshenziswa ngaphakathi kwengqalasizinda yesiteshi esincane sendawo yesikhungo ukuze yehle futhi isabalalise amandla e-DC ahlanzekile ngokuphelele, anamandla aphezulu kumayunithi kagesi asendaweni (ama-PSU) ale mishini ebalulekile.

Ubunjiniyela Obunamandla Bogesi

Njengo-ikhebula le-voltage ephezulu lobunjiniyela kagesi, isilinganiso se-75kV sivame ukusetshenziswa ku:

• Ukufakwa kukagesi ezitimeleni:Ukunikeza amandla omgogodla kumanethiwekhi ezitimela ezisheshayo.

• Imisebenzi Yezimayini:Ukunika amandla imishini emikhulu ebophayo engaphansi komhlaba kanye nezinhlelo zokuhambisa lapho isikhala sincane khona kanye nokwehla kwamandla kagesi kumele kuncishiswe.

• Izikhungo Zedatha:Izikhungo zedatha ze-Hyperscale zibheka kakhulu i-DC backbones ye-voltage ephakathi kuya kwephezulu ukuze kuncishiswe ukulahlekelwa kwe-transformer ephansi futhi kuthuthukiswe ukusebenza kahle kwamandla (i-PUE).
