Qhov sib txawv ntawm DC thiab AC kis tau tus mob

Qhov sib txawv ntawm DC thiab AC kis tau tus mob

Los ntawm cov kev taw qhia ntawm kev pom, txais yuav ± 800 kV UHV DC kis tau tus mob, qhov nruab nrab ntawm txoj kab tsis tas yuav poob taw tes, uas tuaj yeem xa ntau lub zog ncaj qha mus rau qhov chaw thauj khoom loj;nyob rau hauv cov ntaub ntawv ntawm AC / DC thaum uas tig mus kis tau tus mob, nws yuav siv tau ob tog zaus hloov kho kom zoo inhibit lub regional low-frequency oscillation, thiab txhim kho cov kev txwv ntawm ib ntus (dynamic) stability ntawm tus ntoo khaub lig-section;thiab daws qhov teeb meem ntawm tshaj qhov luv-circuit tam sim no ntawm kev txais loj kawg ntawm daim phiaj hluav taws xob.Txais 1000kV AC kis tau tus mob, qhov nruab nrab tuaj yeem poob nrog daim phiaj muaj nuj nqi;ntxiv dag zog rau daim phiaj los txhawb kev loj DC fais fab kis;Hauv paus daws teeb meem ntawm luv luv-circuit tam sim no tshaj tus qauv ntawm loj tau txais daim phiaj kawg thiab qhov tsis tshua muaj peev xwm kis tau tus mob ntawm 500kV kab, thiab optimizing cov qauv ntawm lub hwj chim daim phiaj.

Nyob rau hauv cov nqe lus ntawm kis tau tus mob muaj peev xwm thiab stability kev ua tau zoo, siv ± 800 kV UHV DC kis tau tus mob, kev ruaj ntseg kis tau tus mob nyob ntawm qhov zoo luv Circuit Court piv (ESCR) thiab zoo inertia tas li (Hdc) ntawm daim phiaj ntawm qhov kawg tau txais, nrog rau cov qauv ntawm daim phiaj ntawm qhov kawg xa.Txais 1000 kV AC kis tau tus mob, lub peev xwm kis tau tus mob nyob ntawm lub peev xwm luv luv ntawm txhua qhov kev txhawb nqa ntawm txoj kab thiab qhov kev ncua deb ntawm cov kab sib kis (qhov kev ncua deb ntawm cov ntsiab lus poob ntawm ob qhov chaw nyob sib ze);kev ruaj ntseg kis tau tus mob (synchronization muaj peev xwm) nyob ntawm qhov loj ntawm lub hwj chim lub kaum sab xis ntawm qhov chaw ua hauj lwm (qhov sib txawv ntawm lub hwj chim lub kaum sab xis ntawm ob kawg ntawm kab).

Los ntawm qhov kev xav ntawm cov teeb meem tseem ceeb uas xav tau kev saib xyuas, kev siv ± 800 kV UHV DC kis tau tus mob yuav tsum tsom rau qhov zoo li qub reactive fais fab sib npaug thiab dynamic reactive zog thaub qab thiab voltage stability ntawm qhov kawg ntawm daim phiaj, thiab yuav tsum tsom mus rau lub system. voltage kev ruaj ntseg teeb meem tshwm sim los ntawm ib txhij tsis ua hauj lwm ntawm theem hloov nyob rau hauv lub multi-poob DC feeder system.Kev siv 1000 kV AC kis tau tus mob yuav tsum tau them sai sai rau AC system theem kev hloov kho thiab cov teeb meem kev tswj hluav taws xob thaum hloov pauv kev ua haujlwm;ua tib zoo saib xyuas cov teeb meem xws li kev hloov pauv ntawm lub zog siab hauv cov ntu uas tsis muaj zog nyob rau hauv cov xwm txheej loj;thiab ua tib zoo saib xyuas cov kev phom sij zais ntawm thaj chaw loj ntawm kev sib tsoo thiab lawv cov kev tiv thaiv.
