Ndikukula kwatsopano kwa magetsi atsopano, China yakhala dziko lalikulu kwambiri lamagetsi, magetsi amphepo, kupanga mphamvu za dzuwa, ndi maakaunti a mphamvu zowonjezereka zowonjezereka mosalekeza. Kuti izi zitheke, kupumira mphamvu zamagetsi zoyeserera, kukonzanso ukadaulo wamagetsi ndikofunikira. Izi zimafunikira zida zamagetsi zotsogola kwambiri.
Liubei Converter Station ku Guangxi ndiye malo oyamba osinthira ma UHV padziko lonse lapansi. Imeneyi ndimapulogalamu osakanikirana a DC osakanikirana kwambiri omwe ali ndi mpweya wabwino kwambiri komanso ndimphamvu kwambiri padziko lonse lapansi.
Mbadwo watsopano wamagetsi wosinthira wa DC uli ndi liwiro mwachangu lamphamvu zamagetsi, zomwe zimatha kuzindikira kulipidwa mwachangu kwa magetsi osunthika oyera ndi mphamvu, ndikusintha makono komanso osasunthika kukhala osinthasintha, ndikupangitsa kuti mphamvu yoyera nthawi yomweyo, imatha kuchepetsa nthawi yosokoneza gululi mpaka milliseconds osakwana 100.
Chimodzi mwazofunikira zamagetsi osinthira DC chosinthira ndi gawo losinthasintha. Mtengo wa gawo losinthasintha ndi wofanana ndi uja wamagalimoto akulu. Itha kusinthitsa ma data masauzande masauzande mu sekondi imodzi kuti ikwaniritse bwino mphamvu zotumizira ndikuwongolera kuwongolera ndi kuteteza molondola kwa gridi yamagetsi pamlingo wama microsecond。
Woyamba ± 800kV ultra-high voltage voltage DC converter valve:
Kunliulong DC Demonstration Project ± 800 KV Kunbei chosinthira poyesa pang'ono：
TBEA ikugwira ntchito yopanga zida ndikupanga malo osinthira a Udongliu North Pole 1, okhala ndi mphamvu zonse za 3GW, zokhala ndi maholo awiri a ma valve ndi nsanja 24 zamagetsi.
Gawo lina lalikulu ndi khadi lolamulira, lomwe ndi ubongo wamagetsi osinthira a DC. Pali zida zamagetsi masauzande ambiri pamakadi omwe amaoneka ngati wamba, iliyonse yomwe ili ndi njira yake yotumizira, yokhoza kukwaniritsa kufalikira kwaposachedwa kwambiri kwa Hertz wopitilira 1 biliyoni. ya data yomwe idakwezedwa ndi dongosolo lonse loyendetsa valavu mkati mwa kuphethira kwa diso la munthu la masekondi 0.2.
Ukadaulo uwu ndiye kutalika kwa ukadaulo wogwiritsa ntchito mphamvu zomwe zimphona zapadziko lonse lapansi zikulanda pakadali pano, ndipo pali mayiko atatu okha padziko lapansi omwe angathe kupanga izi.
Valavu yatsopano yosinthira DC yakonzeka kugwira ntchito Ikagwiritsidwa ntchito mu chingwe chosinthira chatsopano cha DC, ntchito ya Kunliulong DC, yomwe inyamula magetsi a kilowatt-maola 33 biliyoni omwe amapangidwa chaka chilichonse ndi Wudongde Hydropower Station, yachisanu ndi chiwiri yapadziko lonse lapansi -sitima yayikulu yamagetsi, ma 1,452 kilomita kupita ku zigawo za Guangdong ndi Guangxi.
Tekinoloje yamagetsi yosinthira (VDC), yomwe imathandizira kuwongolera mwachangu komanso kosavuta magululi, imawerengedwa kuti ndiukadaulo wofunikira kuthana ndi kulumikizana kwakukulu kwa mphamvu yamagetsi mtsogolo.
