Mawu Oyamba: SVG (Static Var Generator), ndiko kuti, high-voltage static var jenereta, yomwe imadziwikanso kuti advanced static var compensator ASVC (Advanced Static Var Compensator) kapena static compensator STATCOM (Static Compensator), SVG (static compensator) ndi The atatu -phase high-power voltage inverter ndiye pachimake, ndipo voteji yake yotulutsa imalumikizidwa ndi dongosolo kudzera pa riyakitala, ndipo imasunga ma frequency ndi gawo monga voteji mbali ya dongosolo, ndipo mphamvu yotulutsa imatsimikiziridwa ndikusintha ubale pakati pa zotulutsa. voteji matalikidwe ndi dongosolo voteji matalikidwe Chikhalidwe ndi mphamvu ya , pamene matalikidwe ake ndi wamkulu kuposa voteji matalikidwe a mbali dongosolo, izo linanena bungwe capacitive zotakasika mphamvu, ndipo pamene ndi yaying'ono kuposa izo, izo linanena bungwe inductive zotakasika mphamvu.Ilo limatanthawuza makamaka chipangizo cha zotakataka zotakasuka mphamvu chipukuta misozi ndi kudzikonda commutated mphamvu semiconductor mlatho converters.
Ndiye kuchuluka kwa kugwiritsa ntchito SVG (static compensator) ndi kotani?
Choyamba, SVG yomwe imagwiritsidwa ntchito kwambiri (static compensator) imagwiritsidwa ntchito kwambiri pamakina odziyimira pawokha amagetsi ogwiritsa ntchito mafakitale.Chifukwa madipatimenti oyenerera a dziko lino, monga dipatimenti yopereka magetsi, aziyang'anira mphamvu yamagetsi ndi mtundu wamagetsi a ogwiritsa ntchito mafakitalewa.Pali zopinga zambiri ndi zolepheretsa.Izi zikutanthauza makamaka kwa ogwiritsa ntchito mafakitale.Kugwiritsa ntchito mphamvu ndikokwera kwambiri.Ogwiritsa ntchito akuyenera kugwiritsa ntchito SVG (Static Compensator) kuti alipire mphamvu za in-situ reactive power.Kumbali imodzi, imatha kuchepetsa kugwiritsa ntchito mphamvu zake ndikukwaniritsa cholinga chopulumutsa mphamvu ndi kuchepetsa utsi, kumbali ina.Kutha kufikira gawo lamagetsi kumakampani.kupatsidwa.Mphamvu yamagetsi ndi zofunikira zamtundu wa mphamvu.
SVG (static compensator) imakhala yabwino kwambiri pakuthana ndi mavuto omwe amayamba chifukwa cha mphamvu yamagetsi, kusinthasintha kwamagetsi, kusinthasintha kwamagetsi ndi kuphulika.Chifukwa chake SVG (static compensator) itha kuthetsedwa mwangwiro.Mchitidwe wobwezera mphamvu zamagetsi zamagetsi zamagetsi zamagetsi.Makamaka ndi zida zina zamagetsi monga capacitors ndi reactors.Pogwiritsa ntchito.Ikhoza kupangitsa mtengo wa integrated reactive power compensation system kutsika.Panthawi imodzimodziyo, chifukwa cha kukula kochepa kwa SVG (Static Compensator), imakhala yokhazikika bwino.Palibe chofunikira kuyang'anira anthu, zomwe zimalolanso kuti minda yamphepo imangidwe kulikonse komwe ali.Kupanga munthawi yomweyo kwa SVG (Static Compensator).
Kwa magwero a ma harmonic omwe amayambitsa zinthu zazikulu ndi ma harmonics apamwamba, mwachitsanzo.Zowopsa zomwe zimachitika nthawi zambiri zimachitika pamakina amagetsi amagetsi.Zotsatira za Gaussian otsetsereka ndi mbali ya mbali idzakhala magetsi a gridi.kupanga mafunde opotoka.Popeza SVG (static compensator) palokha si gwero la ma harmonics.nthawi yomweyo.Lili ndi ntchito zolipirira reactive power factor ndikuchotsa ma harmonics omwe akhudzidwa.
Nthawi yomweyo, SVG (static compensator) ndiyoyeneranso malo omwe zida zamagetsi zingayambitse magawo atatu osagwirizana.Gululi lamagetsi la magawo atatu losalinganiza lidzapanga ma harmonics apamwamba komanso mafunde otsatizana.Pangani kusokoneza kwa magetsi kukhala kovuta kwambiri.Zimayambitsa kusinthasintha kwa magetsi ndi kuphulika.SVG (Static Compensator).Ili ndi liwiro loyankha mwachangu kwambiri.Kuyankha kwamakina ndi ochepera 5ms, ndipo sikungopereka mphamvu yamagetsi yokhazikika ngati zida zamagetsi.ndi reactive current.Panthawi imodzimodziyo, imathanso kuthetsa kusalinganika kwa magawo atatu pogwiritsa ntchito ntchito yake yamalipiro ang'onoang'ono.Limbikitsani kagwiritsidwe ntchito ka zida monga ma traction transfoma, komanso kupondereza ma oscillation otsika kwambiri mudongosolo.
SVG (malo amodzi compensator) utenga angapo kapena PWM luso kuchepetsa kwambiri zili harmonics mu chipukuta misozi panopa, ndi voliyumu ndi mtengo wake ndi ang'onoang'ono kwambiri kuposa wamba chikhalidwe condensers, capacitor reactors, ndi thyristor-analamulira reactors TCR.Imayimira SVC yachikhalidwe ndi zina zotero.SVG static compensator ndiye chitukuko chamtsogolo.
