Iine kukurumidza kukura kwesimba nyowani, China rave iro rakakura nyika yemagetsi emagetsi, simba remhepo, kugadzira simba rezuva, uye magetsi emagetsi anovandudzwa ekuwedzera kuwedzera. Kuita izvi kusagadzikana, inopinda yakachena magetsi simba, kusimudzira simba rekutepfenyura tekinoroji kwakakosha. Izvi zvinoda zvigadzirwa zvemberi zvekufambisa simba.
Liubei Converter Chiteshi muGuangxi ndiyo yekutanga UHV yakawanda-terminal inoshanduka DC inoshandura chiteshi munyika. Iyo zvakare iri yakawanda-yekupedzisira hybrid DC chirongwa ine yakakwira voltage giredhi uye hombe yekufambisa hutachiwana pasirese.
Chizvarwa chitsva cheiyo inoshanduka DC inoshandura vharuvhu ine kukurumidza kumhanya kwesimba mirau, iyo inogona kuona kukurumidza kuripwa kweanoshanduka akachena simba kuchaja uye simba, uye nekushandura ine hukasha uye isingabatike yazvino kuita inochinjika imwe, ichigonesa simba rakachena Panguva imwecheteyo, inogona kudzikisira iyo nguva yekugadzirisa grid kusvika pasi pe100 milliseconds.
Imwe yeiyo musimboti weiyo inoshanduka DC inoshandura vharuvhu ndiyo inoshanduka module. Mutengo wechikamu chinoshanduka chakaenzana neicho chemotokari yepamusoro. Iyo inogona kugadzirisa makumi ezviuru emapoinzi edata mune chiuru chechipiri chechipiri kuti ibudirire kunyatso kudzora kwesimba rekutakura uye kugadzirisa kudzora uye kuchengetedza kwakaringana kweiyo gridhi remagetsi kune iyo microsecond level。
Yekutanga ± 800kV Ultra-yakakwira voltage inoshanduka DC shanduko vharuvhu:
Kunliulong DC Chiratidziro Chirongwa ± 800 KV Kunbei shanduko yekuyedza kuyedza：
TBEA inoita basa rekugadzira michina uye kugadzirwa kweUdongliu North Pole 1 chinoshandura chiteshi, ine huwandu hwakazara hwe3GW, inosanganisira maviri mavhavha emahara uye makumi maviri nemaviri ematafura.
Iyo imwe yepakati chikamu chikamu chekutonga bhodhi kadhi, inova iyo huropi yeiyo inoshanduka DC inoshandura vharuvhu. Kune makumi ezviuru emidziyo yemagetsi pane inoita kunge yakajairwa kadhi bhodhi, imwe neimwe iine tambo yayo yekutapurirana, inokwanisa kuwana yakanyanya kuwanda frequency kutapudza kweanopfuura bhiriyoni rimwe Hertz. ye data yakadhonzwa neiyo yakazara vharuvhu yekudzora system mukati mekubwaira kweziso revanhu remasekonzi 0.2.
Iyi tekinoroji ndiko kukwirira kwekuraira kwesimba rekushandisa tekinoroji iro masimba epasi rose arikutora parizvino, uye kune nyika nhatu chete pasi rose dzinogona kuzvigadzira.
Iyo itsva inoshanduka DC inoshandura vharuvhu yakagadzirira kushanda.Ichashandiswa mune nyowani inoshanduka DC yekufambisa mutsara, iyo Kunliulong DC chirongwa, icho chinotakura iwo mabhiriyoni makumi matatu nematatu emakirowatt-maawa emagetsi anogadzirwa gore rega neWudongde Hydropower Station, yechinomwe pasi rose. -chiteshi chikuru chemagetsi emvura, makiromita 1,452 kusvika kumatunhu eGuangdong uye Guangxi.
Inochinjika yakatwasuka yazvino (VDC) tekinoroji yekutakurisa, iyo inogonesa nekukurumidza uye inochinja-chinja grid mutemo, inoonekwa seyakakosha tekinoroji yekugadzirisa nehukuru-chiyero gridhi kubatana kwesimba rinowedzerwazve mune ramangwana.
