Chiteshi chekutanga cheUHV Multi-terminal Flexible DC Converter pasi rose chakavakwa!

Nekukurumidza kukura kwesimba idzva, China yave nyika huru ine simba remvura, simba remhepo, simba rezuva, uye simba rinogona kushandiswazve, izvo zviri kukonzera kuwedzera kuri kuramba kuchiitika. Kuti simba remagetsi rirambe richichinja-chinja, nguva nenguva, kusimudzira tekinoroji yekufambisa simba kwakakosha. Izvi zvinoda michina yekufambisa simba yepamusoro.

Chiteshi cheLiubei Converter Station chiri muGuangxi ndicho chiteshi chekutanga cheUHV multi-terminal chinochinjika cheDC converter pasi rose. Ichi chirongwa che multi-terminal hybrid DC chine voltage grade yepamusoro uye simba guru rekutumira magetsi pasi rose.

Chizvarwa chitsva chevharuvhu inochinjika yeDC converter ine kumhanya kukuru kwekutonga kwesimba, izvo zvinogona kuita kuti simba remagetsi rakachena riwedzere nekukurumidza, uye zvinoshandura simba remagetsi rinochinja kuita rinochinjika, zvichiita kuti simba rakachena ribatanidzwe kugrid. Panguva imwe chete, zvinogona kuderedza nguva yekugadzirisa dambudziko regrid kusvika pasi pe100 milliseconds.

Chimwe chezvinhu zvakakosha zvevharuvhu inochinjika yeDC converter imodule inochinjika. Mutengo wemodule inochinjika wakaenzana newemota yekare. Inogona kugadzirisa makumi ezviuru zvemapoinzi edata muchiuru chimwe chete chesekondi kuti iwane kutonga kwakarurama kwesimba rekutumira uye kuvandudza kurongeka kwegrid yemagetsi kusvika padanho re microsecond..

Vharuvhu yekutanga pasi rose ye ±800kV ine voltage yakakwira zvakanyanya inochinjika yeDC converter:

Kunliulong DC Demonstration Project ±800 KV Kunbei converter station yekuedza chiedza：

TBEA inoita basa rekugadzira nekugadzira michina yeUdongliu North Pole 1 converter station, ine simba re3GW, inosanganisira mavharuvhu maviri nematombo makumi maviri nemana evharuvhu.
Chimwe chinhu chikuru ibhodhi rekudzora, iro riri uropi hwevharuvhu inochinjika yeDC converter. Kune zviuru zvezvishandiso zvemagetsi pabhodhi rebhodhi rinoita serinojairika, rimwe nerimwe rine tambo yaro yekutumidzira, inokwanisa kuwana kutumirwa kwakawanda kweHertz inodarika bhiriyoni imwe chete. Kugona kukuru uye nekukurumidza kwekugadzirisa data kwakaenzana neka8,000 kedata rinoiswa nehurongwa hwese hwekudzora vharuvhu mukati mekubwaira kweziso remunhu kwemasekondi 0.2.

Tekinoroji iyi ndiyo tekinoroji yepamusoro-soro yekushandisa simba iyo makambani makuru epasi rose ari kutora parizvino, uye kune nyika nhatu chete pasi rose dzinogona kuigadzira.

Vharuvhu itsva inochinjika yeDC converter yagadzirira kushanda. Ichashandiswa mumutsara mutsva unochinjika weDC transmission, Kunliulong DC project, iyo ichatakura magetsi anorema mabhiriyoni makumi matatu nematatu emakirowatt-hours anogadzirwa gore rega rega neWudongde Hydropower Station, chiteshi chemagetsi chechinomwe pakukura pasi rose, chine makiromita chiuru nemazana mana nemakumi mashanu nemaviri kuenda kumapurovhinzi eGuangdong neGuangxi.

Tekinoroji yekutumira magetsi inochinjika zvakananga (VDC), iyo inoita kuti grid regulation ikurumidze uye inochinjika, inoonekwa se tekinoroji yakakosha yekugadzirisa kubatana kukuru kwegrid remagetsi anogona kushandiswazve mune ramangwana.
