Vim li cas HVDC lub tshuab hluav taws xob txawv ntawm lwm lub tshuab hluav taws xob?
1. Kev ntseeg siab ntawm high-voltage DC fais fab mov system yog kev txhim kho zoo heev - lub hom phiaj tseem ceeb ntawm kev siv lub tshuab hluav taws xob siab DC fais fab mov yog los txhim kho kev ruaj ntseg ntawm lub system.
2. Kev ua haujlwm ntawm high-voltage DC fais fab mov system tau zoo heev - UPS hosts uas tau siv dav rau tam sim no yog txhua hom kev hloov pauv hauv online. Thaum tus nqi thauj khoom ntau dua 50 feem pua, kev hloov pauv kev ua haujlwm zoo ib yam li kev hloov hluav taws xob.
3. Cov input tsis tau ntawm high-voltage DC fais fab mov system tau zoo heev. Kev sim teb tau pom tias feem ntau siv 12-pulse online hloov dua siab tshiab UPS host, tom qab ntxiv 11 lim, nws cov khoom siv hluav taws xob feem ntau yog 0.8 rau 0.9, thiab qhov siab tshaj plaws tsuas yog 0.8 rau 0.9. 0.95, cov ntsiab lus tam sim no sib haum xeeb feem ntau yog nyob ib puag ncig 7.5 feem pua.
4. High-voltage DC fais fab mov system, lub peev xwm load tau zoo heev - lub peev xwm load ntawm UPS system yog txwv los ntawm ob yam. Ib qho yog lub zog ntawm lub load. Noj ib yam ntawm cov tswv tsev ntawm cov chaw tsim khoom loj hauv UPS ua piv txwv, cov khoom siv hluav taws xob tso tawm Thaum nws yog 0.5 (capacitive), nws qhov siab tshaj plaws tso cai thauj khoom tsuas yog 50 feem pua; Qhov thib ob yog qhov tam sim no crest yam ntawm lub load, feem ntau tus tsim crest yam ntawm UPS host yog 3, yog hais tias tam sim no crest yam ntawm lub load yog ntau tshaj 3, UPS host yuav poob. siv tau.
5. High-voltage DC fais fab mov system, me me kis voltage poob - DC cable kab tsis muaj teeb meem ntawm capacitive tam sim no nyob rau hauv AC cable kab, tsis muaj magnetic induction poob thiab dielectric poob, yeej tsuas yog cov tub ntxhais hlau tsis kam, kuj tsis tshua muaj rwb thaiv tsev voltage. , DC kis tau tus mob thev naus laus zis Nws yog qhov tsim nyog rau kev sib kis mus ntev, thiab ua tau raws li lub tebchaws tam sim no rau kev txuag hluav taws xob, txo kev noj thiab kev tiv thaiv ib puag ncig. Nws belongs rau lub tswv yim ntsuab thiab ib puag ncig tus phooj ywg fais fab mov.
Tau kawg, kuj tseem muaj teeb meem hauv DC kis tau tus mob, xws li tus nqi siab ntawm qhov chaw nres tsheb converter, tsis muaj peev xwm overload, muaj peev xwm loj ntawm cov khoom siv hluav taws xob reactive, hloov chaw nres tsheb nws tus kheej yog qhov loj ntawm kev sib haum xeeb, nyuaj tsim DC high voltage Circuit Court breakers thiab tus nqi siab.
