A reactive simba muripo wemagetsi mudziyo, unozivikanwawo sesimba rekugadzirisa zvinhu, unokosha musimba remagetsi.Basa rayo guru nderekuvandudza simba remagetsi ekupa uye kugovera sisitimu, nekudaro ichiwedzera mashandisirwo ekufambisa uye midziyo yemagetsi, kuvandudza kushanda kwesimba, uye kuderedza mutengo wemagetsi.Mukuwedzera, kuisa dynamic reactive power compensation device panzvimbo dzakakodzera mumitsara yekufambisa kure-kure inogona kuvandudza kugadzikana kwehurongwa hwekutumira, kuwedzera simba rekufambisa, uye kudzikamisa magetsi pamagumo ekugamuchira uye grid.Reactive magetsi ekubhadhara magetsi. matanho akawanda ekukura.Mumazuva ekutanga, synchronous phase advances vaive vamiririri vemazuva ese, asi zvishoma nezvishoma vakabviswa nekuda kwehukuru hwavo uye mutengo wakakwira.Yechipiri nzira yaive kushandisa parallel capacitors, iyo yaive neyakanakira yakaderera mutengo uye nyore kuisa uye kushandisa.Zvisinei, nzira iyi inoda kugadzirisa nyaya dzakadai se harmonics uye mamwe matambudziko ehutano hwemagetsi angave aripo muhurongwa, uye kushandiswa kwechene capacitors kwave kusingawanzoitiki.Parizvino, iyo series capacitor compensation device inzira inoshandiswa zvakanyanya yekuvandudza simba rekuita.Kana mutoro wemushandisi sisitimu uchienderera mberi nekugadzirwa uye huwandu hwekuchinja kwemutoro husina kukwirira, zvinowanzokurudzirwa kushandisa yakagadziriswa muripo maitiro ane capacitors (FC).Neimwe nzira, otomatiki muripo wemodhi inodzorwa nevanobatika uye stepwise switching inogona kushandiswa, iyo yakakodzera kune ese epakati uye yakaderera voltage kugovera uye kugovera masisitimu.Kuti muripo unokurumidza muzviitiko zvekukurumidza kuchinja kwemutoro kana kukanganiswa mitoro, senge mukusanganiswa kweindasitiri yerabha. michina, uko kudiwa kwesimba reactive kunochinja nekukurumidza, iyo yakajairwa reactive simba otomatiki muripo masisitimu, ayo anoshandisa capacitors, ane painogumira.Kana ma capacitors akabviswa kubva pamagetsi emagetsi, pane yakasara voltage pakati pematanda maviri e capacitor.Kukura kweiyo yakasara voltage haigone kufanotaurwa uye inoda 1-3 maminetsi enguva yekubuda.Naizvozvo, nguva iri pakati pekubatanidzazve kune grid yemagetsi inoda kumirira kusvika yasara voltage yadzikiswa kusvika pazasi 50V, zvichikonzera kushaikwa kwekupindura nekukurumidza.Pamusoro pezvo, nekuda kwekuvapo kwehuwandu hukuru hwema harmonics muhurongwa, LC-tuned yekusefa muripo wemidziyo inoumbwa nemacapacitor uye mareactor inoda huwandu hukuru kuti ive nechokwadi chekuchengetedzwa kwemacapacitor, asi inogona zvakare kutungamira mukuwedzeredza uye kuita kuti sisitimu iite. kuva capacitive.Saka, iyo static var compensator (SVC) akaberekwa.Iyo yakajairika mumiriri weSVC inoumbwa neThyristor Controlled Reactor (TCR) uye fixed capacitor (FC).Chinhu chakakosha cheiyo static var compensator kugona kwayo kuramba ichigadzirisa reactive simba remuripo mudziyo nekudzora kukonzeresa kunonoka angle ye thyristors muTCR.SVC inonyanya kushandiswa mukati mepakati kusvika kune yakakwira magetsi ekugovera masisitimu, uye inonyanya kukodzera mamiriro ane hukuru hwekuremedza, matambudziko akakomba eharmonic, mitoro yekukanganisa, uye yakakwirira mitoro yekuchinja, senge simbi zvigayo, maindasitiri erabha, asiri-ferrous metallurgy, Nekugadzirwa kwemagetsi emagetsi tekinoroji, kunyanya kubuda kweIGBT zvishandiso uye kufambira mberi mukutonga tekinoroji, imwe mhando yemagetsi ekugadzirisa magetsi yakabuda iyo yakasiyana neyechinyakare capacitor uye reactor-based zvishandiso. .Iyi ndiyo Static Var Jenareta (SVG), inoshandisa PWM (Pulse Width Modulation) yekudzora tekinoroji kugadzira kana kutora simba rinoshanda.SVG haidi kuverengera kuverengera kweiyo system kana isiri kushandiswa, sezvo inoshandisa bhiriji inverter maseketi ane akawanda-level kana PWM tekinoroji.Uyezve, ichienzaniswa neSVC, SVG ine zvakanakira saizi diki, inokurumidza kuenderera uye ine simba kutsvedzerera kwesimba rinoshanda, uye kugona kubhadharira zvese inductive uye capacitive simba.
