Bitewe n’iterambere ryihuse ry’ingufu nshya, Ubushinwa bwabaye igihugu kinini gifite ingufu zikomoka ku mazi, umuyaga, ingufu zikomoka ku mirasire y’izuba, n’ingufu zishobora kongera kwiyongera. Kugira ngo izi ngufu z’amashanyarazi zihindagurika kandi zisukuye, ni ngombwa kuvugurura ikoranabuhanga ryo kohereza ingufu. Ibi bisaba ibikoresho bigezweho byo kohereza ingufu.
Sitasiyo ya Liubei Converter i Guangxi ni yo sitasiyo ya mbere ya UHV multi-terminal flexible DC converter ku isi. Ni kandi umushinga wa multi-terminal hybrid DC ufite volteji nyinshi kandi ufite ubushobozi bwo kohereza ubutumwa bwinshi ku isi.
Itsinda rishya rya flexible DC converter valve rifite umuvuduko wihuta wo kugenzura ingufu, rishobora kwishyura vuba ingufu zihindagurika, kandi rigahindura ingufu zidasanzwe kandi zidahinduka, bigatuma ingufu zisukuye zishobora guhuzwa n’urusobe rw’amashanyarazi. Muri icyo gihe, bishobora kugabanya igihe cyo gukemura ibibazo ku rusobe rw’amashanyarazi kugeza munsi ya milisegonda 100.
Kimwe mu bintu by'ingenzi bya valve ya DC converter ni module ihindagurika. Igiciro cya module ihindagurika kingana n'icy'imodoka ishaje. Ishobora gutunganya amakuru ibihumbi mirongo mu gice kimwe cy'isegonda kugira ngo igenzure neza ingufu zo kohereza no kunoza uburyo bwo kugenzura no kurinda amashanyarazi kugeza ku rwego rwa microsecond..
Valve ya mbere ku isi ihindura voltage ya ±800kV ifite voltage nyinshi cyane:
Umushinga wo kwerekana umushinga wa Kunliulong DC ± 800 KV Kunbei converter station yo gupima urumuri:
TBEA ikora akazi ko guteza imbere no gukora ibikoresho bya sitasiyo ya Udongliu North Pole 1 converter, ifite ubushobozi bwo gutanga 3GW, irimo utuzu tubiri tw’amashanyarazi n’iminara 24 y’amashanyarazi.
Ikindi gice cy'ingenzi ni ikarita y'ikibaho cyo kugenzura, ari na yo ubwonko bwa valve ihindura DC. Hari ibikoresho by'ikoranabuhanga ibihumbi mirongo kuri ikarita isa n'isanzwe, buri kimwe muri byo gifite umurongo wacyo wo kohereza amakuru, gishobora kohereza amakuru arenga miliyari 1 ya Hertz. Ubushobozi nk'ubwo bwo gutunganya amakuru bungana n'inshuro 8.000 z'amakuru ashyirwa kuri sisitemu yose yo kugenzura valve mu kanya gato k'ijisho ry'umuntu mu masegonda 0.2.
Iri koranabuhanga ni ryo koranabuhanga rikomeye cyane rikoreshwa mu gukoresha ingufu, ibi bihugu bikomeye ku isi birimo gufata muri iki gihe, kandi hari ibihugu bitatu gusa ku isi bishobora kurikora.
Valve nshya ya DC converter yiteguye gukoreshwa. Izakoreshwa mu murongo mushya wa DC transmission, umushinga wa Kunliulong DC, uzatwara miliyari 33 z'amashanyarazi akorwa buri mwaka na sitasiyo ya Wudongde Hydropower Station, sitasiyo ya karindwi nini ku isi y'amashanyarazi, ifite uburebure bwa kilometero 1,452 ugana mu ntara za Guangdong na Guangxi.
Ikoranabuhanga ryo kohereza ingufu zikomoka ku muyoboro w’amashanyarazi (VDC), rituma habaho kugenzura imiyoboro y’amashanyarazi byihuse kandi binoze, rifatwa nk'ikoranabuhanga ry'ingenzi mu guhangana n'umuyoboro munini w’amashanyarazi akomoka ku muyoboro w’amashanyarazi mu gihe kizaza.
