Parizvino, yakanakisa harmonic kudzora kugona mumusika ndeye APF yakatevedzana yakaderera-voltage inoshanda sefa yakagadziriswa uye inogadzirwa neHongyan Electric.Ichi chikamu chemagetsi chemagetsi chakavakirwa pane yazvino yekutarisa uye ikozvino yekusuma tekinoroji.Iyo harmonic yazvino chikamu kuti chibhadharwe chinowanikwa zvinoenderana nekutarisa mutoro wazvino waveform.Nekudzora iyo IGBT inokonzeresa, iyo pulse wide modulation shanduko tekinoroji inoshandiswa kuunza harmonics, reactive components uye currents munzira yakatarisana neiyo simba rekugovera sisitimu kuti uwane mhedzisiro yekubvisa harmonics.Iyo inoshanda sefa inogona kudarika 95%, nekudaro ichivandudza kuchengetedza chinhu uye kuvimbika kwesimba rekupa simba, uye kuzadzisa chinangwa chekuchengetedzwa kwezvakatipoteredza, kuchengetedza simba uye kusimudzira kushanda nesimba.
Kufunga nezve utility kambani mirau ndiyo yakakosha mutyairi wemakambani kuita harmonic hutongi.Iyo kambani inopa magetsi inosungirwa kuburitsa akakodzera emagetsi emagetsi emagetsi emagetsi vatengi.Naizvozvo, kambani yemagetsi inopa pulse ikozvino kutonga zvinodiwa kune vashandisi vanogona kusvibisa grid.Sezvo makambani akawanda uye akawanda achida emhando yepamusoro yemagetsi, makambani emagetsi anoisa pamberi zvakaomarara zvinodiwa kune magetsi einjiniya vatengi.
Kazhinji kutaura, chikamu cheharmonic control uye centralized harmonic control inogona kusanganiswa kugadzira inodhura-inoshanda mhinduro.Kune harmonic sosi mitoro ine simba repamusoro (senge yepakati frequency induction furnaces, soft starters, etc.).), uchishandisa mafirita e-ultra-high-voltage harmonic emunharaunda harmonic control kuderedza harmonic yazvino inounzwa mugedhi remagetsi.Kune discrete system mitoro ine simba diki uye simba rakagovaniswa, manejimendi akabatana anofanirwa kuitwa mubhazi rehurongwa.Unogona kushandisa Hongyan's inoshanda sefa kana passive sefa.
Iyo yekunatsa uye makemikari indasitiri yeasina-ferrous simbi inofanirwa kushandisa maitiro e electrolysis, saka yakakwirira-simba rectifier yakakosha.Vanhu vanotora kugadzirwa kwehydrogen ne electrolysis yemvura semuenzaniso.Vanhu vanofanira kugadzirisa seti ye rectifier transformer uye thyristor rectifier cabinet.Iyo ballast nzira ndeye matanhatu-phase kaviri inverted nyeredzi mhando.Iyo inogadzirwa alternating current inoshandiswa kune electrolytic cell: 10KV/50HZ-rectifier transformer-phase voltage 172V*1.732 phase voltage 2160A-rectifier cabinet-AC 7200A/179V-electrolytic cell.Rectifier transformer: nhanhatu-chikamu kaviri reverse nyeredzi yakaenzana yakatevedzana reactor kana matatu-chikamu shanu-column matanhatu-chikamu kaviri reverse nyeredzi.Input line volume: 1576 kVA valve side volume 2230 kVA type volume 1902 kVA thyristor rectifier cabinet K671-7200 A/1179 volts (maseti mana ese).Iyo yekugadziridza midziyo inokonzeresa yakawanda pulsed ikozvino, iyo ichaisa zvakanyanya mungozi kunaka kwesimba remagetsi grid.
Mune yakakwirira-simba-yechitatu-chikamu chakazara-bhiriji 6-pulse rectifier mudziyo, iyo yakakwirira-yakarongeka harmonics inogadzirwa neakaunzi rectifier ye25-33% yehuwandu hwepamusoro-order harmonics, izvo zvinokonzeresa kukuvadza kukuru kune gidhi remagetsi, uye hunhu hwemhando yepamusoro-soro inogadzirwa ndeye 6N±1 nguva, kureva kuti, hunhu hwenguva kudivi revharuvhu ndeye 5th, 7th, 11th, 13th, 17th, 19th, 23rd, 25th, zvichingodaro, uye yechishanu uye yechinomwe kumusoro. harmonic zvikamu zvinogadzirwa nePCC point padivi guru retiweki Iyo hunhu hwepamusoro-yakarongeka harmonics iri padivi revhavha imwechete, pakati peiyo iyo 5th order yakakura, uye 7th kurongeka kunoderera.Kushanda kwakafanana kweboka rekugadzirisa shanduko ine phase-shifting windings inogona kuumba 12 pulses, uye hunhu hwenguva yetiweki side i11 nguva, 13 nguva, 23 nguva, 25 nguva, zvichingodaro, uye gumi neimwe nguva uye gumi nenhatu. chikuru.
Kana pasina mudziyo wekusefa wakaiswa padivi regidhi kana parutivi rwevharuvhu, iyo yakazara pulse ikozvino jekiseni mugidhi ichapfuura iyo indasitiri chiyero chekambani yedu, uye hunhu hweharmonic ikozvino jekiseni mushanduro huru ichapfuurawo kukosha kwekutonga kwekambani. chiyero cheindasitiri yekambani yedu.Yepamusoro harmonics inokonzeresa tambo dzekugovera, kupisa kweshanduko, zvisizvo zvemubhadharo zvishandiso hazvigone kubva mufekitori, kusvibiswa kwemhando yekukurukurirana, kusashanda zvakanaka kwemhepo, kuvhiyiwa kwejenareta uye mamwe mamiriro akashata.
Kazhinji kutaura, mune yakakura simba network yesystem, hunhu hwepamusoro harmonics hunogona kubviswa nekushandisa passive filter (fc) zvishandiso, uye zvinangwa zvekutonga zvinogona kuzadzikiswa.Muchiitiko chemagetsi emagetsi maduku, chinangwa chekubata nepamusoro-soro harmonics yakakwirira.Pamusoro pekuisa yakakura-inogoneka passive sefa mudziyo, diki-inokwana inoshanda sefa (apf) inogona zvakare kushandiswa kuwana simba remhando yekupikisa inodiwa.Yekugadzirisa masisitimu ekumisikidza ane nzira dzakasiyana dzekubatanidza, edu ehunyanzvi mafirita ekubhadhara masisitimu ane akasiyana anotangwa magadzirirwo.Mushure mekuedzwa pa-saiti, vanogona "kugadzirisa" vatengi uye kusarudza chirongwa chekurapa chinoenderana nemamiriro chaiwo pane saiti.
