1) Dynamic them nyiaj reactive zog, txo cov kab poob, txuag hluav taws xob thiab siv
Cov khoom loj hauv kev faib khoom, xws li asynchronous motors, induction furnaces thiab cov cuab yeej muaj peev xwm loj rectifier, hluav taws xob.Lub hwj chim locomotive, thiab lwm yam, tuaj yeem tshwm sim raws li inductive hauv kev ua haujlwm, uas yuav tsum tau siv ntau lub zog reactive thiab nce lub zog. muab kab.Kev poob ntawm cov hluav taws xob hluav taws xob ntawm txoj kev txo cov hluav taws xob zoo, thiab cov hluav taws xob reactive kuj tseem txo cov hluav taws xob tsim hluav taws xob, kev sib kis, thiab cov khoom siv hluav taws xob.
Tus nqi siv tau zoo ntawm qhov chaw tos txais;Rau cov neeg siv hluav taws xob, cov khoom siv hluav taws xob tsawg yuav ua rau tus nqi hluav taws xob nce ntxiv thiab nce qhov kev hloov pauv.Kev poob siab, nce nqi ntau lawm.SVG dynamic reactive fais fab generator tuaj yeem ua raws li qhov kev hloov pauv ntawm lub zog reactive kom paub txog cov nyiaj them rov qab ntawm lub zog reactive, txo cov kab poob, thiab ua kom zoo dua qhov kev siv hluav taws xob tsim hluav taws xob, kev sib kis thiab khoom siv.
2) Dynamic lim harmonics, txhim kho lub zog zoo, txuag hluav taws xob thiab txo kev noj
Lub nonlinear load feem ntau txhaj ib tug loj npaum li cas ntawm harmonics mus rau hauv pej xeem lub hwj chim network thaum generating qhov cuam tshuam reactive hwj chim.The SVG dynamic reactive fais fab generator txais lub active lim tshuab siv IGBT ua ib lub hwj chim semiconductor ntaus ntawv.Cov txheej txheem muaj qhov zoo ntawm cov lus teb ceev ceev, muaj kev ntseeg siab, dynamic nrhiav thiab lim cov harmonics, thiab dynamic reactive zog tsim ntawm SVG.Cov cuab yeej muaj txiaj ntsig zoo xws li kev ua haujlwm lim dej tsis cuam tshuam los ntawm kev hloov pauv hauv qhov system tsis, tsis muaj kev phom sij ntawm kev sib haum xeeb amplification, thiab lwm yam. Nws yog lub zog txuag kev daws teeb meem rau dynamic reactive zog them thiab kev sib haum xeeb tswj.
3) Transmission system stability tswj los txhim kho kab kis tau tus mob
SVG dynamic reactive fais fab generatortuaj yeem ntsia tau rau hauv cov kab sib txuas ntev ntev tsis tsuas yog nyob rau hauv ib txwm muaj kev them nyiaj rov qab lub zog ntawm txoj kab, thiab tuaj yeem muab sijhawm thiab ceev reactive zog hloov kho thaum lub cev tsis ua haujlwm.Tshooj lus, damping coefficient oscillation, txhim kho kev ruaj ntseg ntawm kev sib kis, thiaj li ua tau zoo txhim kho cov kab sib kis tau zoo.
4) Tswj lub load davhlau ya nyob twg voltage thiab ntxiv dag zog rau qhov system voltage stability
Rau qhov chaw thauj khoom, vim tias lub peev xwm thauj khoom loj, thiab tsis muaj qhov loj reactive fais fab kev txhawb nqa, nws yog ib qho yooj yim los ua.Tsawg voltage lossis txawm tias qhov hluav taws xob tawg tawg.SVG dynamic reactive fais fab generatortsis muaj kev cai ceev ceev.Kev ua haujlwm ntawm lub zog tuaj yeem tswj xyuas qhov load sab voltage thiab txhim kho qhov kev ruaj ntseg ntawm lub zog hluav taws xob.
5) Voltage fluctuation thiab flicker suppression
Nonlinear loads, xws li hluav taws xob arc rauv, dov mills, electrified railways, thiab lwm yam, yog tshwm sim los ntawm kev hloov ceev ntawm load voltage.Kev hloov pauv thiab flickers, tsis tuaj yeem ua tau raws li tus neeg siv cov kev xav tau ntawm cov khoom siv hluav taws xob zoo, yuav ua rau cov khoom siv tsis zoo ntawm kev ua haujlwm, Kev sib tsoo xws li overcurrent, overheating, misoperation ntawm kev tiv thaiv cov cuab yeej thiab cov khoom siv hluav taws xob tshwm sim, thiab cov khoom siv thiab kev tsim khoom.Ob qho tib si efficiency thiab cov khoom zoo yuav raug kev txom nyem.Voltage fluctuation thiab flicker yog ib qho tseem ceeb rau kev ruaj ntseg thiab kev noj qab haus huv ntawm tib neeg.Kev tsis txaus siab heev.Tag nrho cov lus teb ceev ntawm SVG dynamic reactive fais fab generators ntawm tsawg tshaj li 10ms ua rau nws tshwj xeeb tshaj yog haum rau kev tsuj ntawm voltage fluctuations thiab flickers, thiab lub International Power Grid (CRGRE) kuj pom zoo kom nws raws li cov kev daws teeb meem rau kev tiv thaiv ntawm voltage fluctuations thiab flickers. tshwm sim los ntawm kev hloov pauv ceev ceev xws li hluav taws xob arc rauv taws.
6) Kev them nyiaj rau peb-theem tsis sib npaug
Peb-theem voltage tsis txaus ua rau muaj kev puas tsuaj loj rau cov neeg siv khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sib kis thiab hloov pauv ntawm daim phiaj.Nws ua rau cov ntsiab lus nruab nrab los ua ib qho hluav taws xob siab rau hauv av, uas ua rau cov khoom siv hluav taws xob sib sau ua ke ntawm cov hluav taws xob zoo li qub thiab ua rau muaj kev puas tsuaj rau cov neeg tuag taus;Qhov tsis zoo ua ntu zus tam sim no yuav ua rau kom poob ntawm qhov hloov pauv, ua rau lub tshuab hluav taws xob cua sov, thiab txo qhov muaj peev xwm ua tau zoo.
