Thaum xaiv cov khoom, ntau tus neeg siv khoom feem ntau nug kuv tias yog dab tsiSVGthiab qhov txawv ntawm nws thiab SVC yog dab tsi?Cia kuv muab qee qhov kev taw qhia rau koj, Kuv vam tias yuav muaj txiaj ntsig rau koj xaiv.
Rau SVC, peb tuaj yeem xav tias nws yog lub zog muaj zog reactive.Nws tuaj yeem muab lub zog hluav taws xob rau lub zog hluav taws xob raws li qhov xav tau ntawm kev nkag mus rau hauv daim phiaj hluav taws xob, thiab tseem tuaj yeem nqus tau qhov ntau tshaj inductive reactive zog ntawm daim phiaj hluav taws xob, thiab lub txhab nyiaj capacitor feem ntau txuas nrog lub zog hluav taws xob raws li lub txhab nyiaj lim dej. , uas tuaj yeem muab lub zog reactive rau daim phiaj fais fab.Thaum daim phiaj tsis xav tau ntau lub zog reactive, lub zog reactive reactor no tuaj yeem nqus tau los ntawm lub tshuab hluav taws xob sib luag.Lub reactor tam sim no yog tswj los ntawm thyristor valve teeb.Los ntawm kev kho lub thyristor trigger theem Lub kaum sab xis, peb tuaj yeem hloov qhov txiaj ntsig zoo ntawm qhov tam sim no ntws los ntawm lub reactor, thiaj li ua kom ntseeg tau tias lub zog reactive ntawm SVC ntawm qhov chaw nkag ntawm kab sib chaws tuaj yeem cia li stabilize qhov voltage ntawm qhov taw tes hauv qhov teev. ntau yam, thiab ua si lub luag hauj lwm ntawm reactive zog them nyiaj ntawm daim phiaj.
SVGyog ib qho khoom siv hluav taws xob raug hluav taws xob, uas yog tsim los ntawm peb qhov yooj yim ua haujlwm modules: nrhiav pom module, tswj kev ua haujlwm module thiab cov nyiaj them poob haujlwm.Nws txoj haujlwm ua haujlwm yog txhawm rau txheeb xyuas cov ntaub ntawv tam sim no ntawm CT sab nraud, thiab tom qab ntawd txheeb xyuas cov ntaub ntawv tam sim no, xws li PF, S, Q, thiab lwm yam, los ntawm kev tswj cov nti;Tom qab ntawd tus maub los muab lub teeb liab them nyiaj, thiab thaum kawg lub inverter Circuit Court tsim los ntawm lub zog hluav taws xob hluav taws xob inverter Circuit Court xa tawm cov nyiaj them tam sim no.
CovSVG static varLub tshuab hluav taws xob muaj ib qho kev sib txuas ntawm tus kheej txuas txuas hluav taws xob uas tsim los ntawm lub tshuab hluav taws xob tig tawm hluav taws xob (IGBT), uas txuas nrog lub zog hluav taws xob sib txuas los ntawm lub reactor, thiab qhov amplitude thiab theem ntawm cov zis voltage ntawm AC sab ntawm lub tshuab hluav taws xob. choj Circuit Court tuaj yeem hloov kho kom raug, lossis tam sim no ntawm AC sab tuaj yeem tswj tau ncaj qha.Ceev nrooj nqus los yog tawm lub zog reactive uas yuav tsum tau ua kom tiav lub hom phiaj ntawm kev hloov pauv sai ntawm lub zog reactive.Raws li cov khoom siv them nyiaj ua haujlwm, nws tuaj yeem tsis tsuas yog taug qab lub impulse tam sim no ntawm impulse load, tab sis kuj taug qab thiab them nyiaj rau kev sib haum xeeb tam sim no.
SVGthiab SVC ua haujlwm txawv.SVG yog cov khoom siv hluav taws xob rov ua haujlwm raws li cov khoom siv hluav taws xob.Nws kho lub zog reactive los ntawm kev tswj lub hauv thiab tawm ntawm cov khoom siv hluav taws xob hluav taws xob.SVC yog cov khoom siv hluav taws xob reactive raws li cov khoom siv reactance, uas kho lub zog reactive los ntawm kev tswj cov nqi reactance ntawm cov reactor sib txawv.Yog li ntawd, SVG muaj cov lus teb sai dua thiab raug siab dua, thaum SVC muaj peev xwm ntau dua thiab ua haujlwm ruaj khov dua.
SVG thiab SVC raug tswj sib txawv.Static var generatorsiv hom tswj tam sim no, uas yog, raws li theem thiab amplitude ntawm tam sim no los tswj cov hluav taws xob hluav taws xob rau thiab tawm.Hom kev tswj no tuaj yeem ua tiav qhov kev hloov pauv ntawm lub zog reactive, tab sis nws yuav tsum tau teb siab ceev ntawm tam sim no.Thiab SVC txais yuav voltage tswj hom, uas yog, raws li theem thiab amplitude ntawm qhov voltage los tswj tus nqi reactance ntawm qhov sib txawv reactor.Qhov kev tswj hwm no tuaj yeem paub qhov kev hloov kho ruaj khov ntawm lub zog reactive, tab sis nws yuav tsum muaj qhov hluav taws xob siab teb ceev.
Lub Scope ntawm kev siv SVG thiab SVC kuj txawv.SVG yog qhov tsim nyog rau cov ntawv thov uas xav tau kev hloov pauv hluav taws xob siab, xws li cov chaw tsim hluav taws xob, cov chaw siv hluav taws xob thiab cov chaw lag luam loj.Nws tuaj yeem txhim kho kev ruaj ntseg voltage thiab lub zog zoo ntawm lub zog hluav taws xob los ntawm cov lus teb ceev thiab kev tswj xyuas meej.SVC yog tsim rau cov ntawv thov uas yuav tsum tau muaj kev hloov pauv tam sim no, xws li hluav taws xob arc rauv, kev tsheb ciav hlau thiab cov mines.Nws tuaj yeem txhim kho lub zog zoo thiab ruaj khov ntawm lub zog hluav taws xob los ntawm
kho qhov tam sim no stably.
