static var compensator (SVC) inali ntchito

Chida cholipiritsa mphamvu, chomwe chimadziwikanso ngati chipangizo chowongolera mphamvu, ndichofunika kwambiri pamakina amagetsi.Ntchito yake yayikulu ndikuwongolera mphamvu yamagetsi pamagetsi operekera ndi kugawa, potero kukulitsa mphamvu yogwiritsira ntchito zida zotumizira ndi ma substation, kukonza mphamvu zamagetsi, ndikuchepetsa mtengo wamagetsi.Kuphatikiza apo, kukhazikitsa zida zolipirira mphamvu zamagetsi zokhazikika pamalo oyenerera m'mizere yotumizira mtunda wautali kumatha kuwongolera kukhazikika kwa njira yotumizira, kukulitsa mphamvu yotumizira, ndikukhazikitsa voteji pamapeto olandila ndi grid. magawo angapo a chitukuko.M'masiku oyambilira, otsogolera gawo lofananira anali oyimira, koma adachotsedwa pang'onopang'ono chifukwa cha kukula kwawo kwakukulu komanso kukwera mtengo.Njira yachiwiri inali kugwiritsa ntchito ma parallel capacitors, omwe anali ndi ubwino waukulu wa mtengo wotsika komanso kuyika kosavuta ndi kugwiritsa ntchito.Komabe, njirayi imafuna kuthana ndi nkhani monga ma harmonics ndi mavuto ena amphamvu omwe angakhalepo mu dongosolo, ndipo kugwiritsa ntchito ma capacitors oyera kwakhala kocheperako.Pamene katundu wa makina ogwiritsira ntchito akupangidwa mosalekeza ndipo chiwongoladzanja chosinthira sichikukwera, nthawi zambiri tikulimbikitsidwa kugwiritsa ntchito njira zolipirira zokhazikika ndi ma capacitor (FC).Kapenanso, njira yolipirira yodziwikiratu yomwe imayang'aniridwa ndi olumikizirana ndi kusinthana kwapang'onopang'ono ingagwiritsidwe ntchito, yomwe ili yoyenera kwa onse apakatikati ndi otsika voteji komanso machitidwe ogawa.Kulipiridwa mwachangu pakusintha kwachangu kapena katundu, monga kusakanikirana kwamakampani amphira. makina, pomwe kufunikira kwa mphamvu zotakataka kumasintha mwachangu, makina ochiritsira ochiritsira okhazikika, omwe amagwiritsa ntchito ma capacitors, ali ndi malire.Pamene ma capacitor achotsedwa ku gridi yamagetsi, pali voteji yotsalira pakati pa mitengo iwiri ya capacitor.Kukula kwa voteji yotsalira sikunganenedweratu ndipo kumafuna mphindi 1-3 za nthawi yotulutsa.Choncho, nthawi yapakati pa kulumikizanso ku gridi yamagetsi imayenera kudikirira mpaka magetsi otsalirawo achepetsedwa kukhala pansi pa 50V, zomwe zimapangitsa kuti asayankhe mwamsanga.Kuonjezera apo, chifukwa cha kukhalapo kwa ma harmonics ambiri m'dongosolo, LC-tuned filtering compensation zipangizo zopangidwa ndi capacitors ndi reactors zimafuna mphamvu zazikulu kuti zitsimikizire chitetezo cha ma capacitors, koma zingayambitsenso kubwezeredwa ndikupangitsa dongosolo kuti likhale lolimba. kukhala capacitive.Motero, static var compensator (Mtengo wa SVC) anabadwa.Oimira SVC amapangidwa ndi Thyristor Controlled Reactor (TCR) ndi fixed capacitor (FC).Mbali yofunika ya static var compensator ndi luso lake mosalekeza kusintha mphamvu zotakasika za chipangizo chipukuta misozi ndi kulamulira kuyambitsa kuchedwa ngodya ya thyristors mu TCR.SVC makamaka ntchito sing'anga ndi mkulu voteji kachitidwe kugawa, ndipo makamaka oyenera zochitika ndi mphamvu katundu katundu, mavuto aakulu harmonic, katundu zimakhudza, ndi mkulu katundu kusintha mitengo, monga mphero zitsulo, mafakitale mphira, zitsulo nonferrous, zitsulo processing, ndi mkulu-liwiro njanji.Ndi chitukuko cha luso zamagetsi zamagetsi, makamaka zikamera wa zipangizo IGBT ndi kupita patsogolo luso kulamulira, mtundu wina wa zotakasika mphamvu chipukuta misozi chipangizo chatulukira kuti n'chosiyana ndi capacitors chikhalidwe ndi reactors zochokera zipangizo. .Iyi ndi Static Var Generator (SVG), yomwe imagwiritsa ntchito ukadaulo wowongolera wa PWM (Pulse Width Modulation) kuti ipange kapena kuyamwa mphamvu zogwira ntchito.SVG sifunikira kuwerengera kwadongosolo kwadongosolo ikalibe kugwiritsidwa ntchito, chifukwa imagwiritsa ntchito mabwalo osinthira mlatho okhala ndi ukadaulo wamitundu yambiri kapena PWM.Kuphatikiza apo, poyerekeza ndi SVC, SVG ili ndi maubwino a kukula kocheperako, kusalaza kofulumira komanso kosunthika kwamphamvu yogwira ntchito, komanso kuthekera kolipirira mphamvu zochititsa chidwi komanso zopatsa mphamvu.
