Nekushandiswa kwakakura kweiyo dhizaini yekumhanyisa dhiraivha, servo, kumusoro uye zvimwe zvigadzirwa, huwandu hukuru hwemaharmonics hwakaonekwa mugedhi remagetsi, uye maharmonics akaunza matambudziko makuru emhando yemagetsi.Kuti tigadzirise dambudziko reharmonic mugidhi remagetsi, kambani yedu yakagadzira matatu-nhanhoactive sefazvichibva pane maviri-level inoshanda sefa.
Active harmonic sefainogona kushandiswa zvakanyanya mumaindasitiri, kutengeserana uye masangano ekugovera network, akadai se: magetsi masisitimu, electrolytic plating mabhizinesi, midziyo yekuchenesa mvura, petrochemical enterprises, zvitoro zvikuru uye zvivakwa zvehofisi, mabhizinesi emagetsi emagetsi, airport/port magetsi ekupa masisitimu, masangano ekurapa. , etc. Maererano nezvinhu zvakasiyana-siyana zvekushandisa, kushandiswa kweinoshanda simba sefaichaita basa mukuona kuvimbika kwemagetsi, kuderedza kupindira, kuvandudza mhando yechigadzirwa, kuwedzera hupenyu hwemidziyo uye kuderedza kukuvara kwemidziyo.
Iyo 3rd harmonic mune mazhinji semiconductor maindasitiri akakomba, zvakanyanya nekuda kwehuwandu hukuru hweimwe-chikamu chekugadzirisa midziyo inoshandiswa mumabhizinesi.Yechitatu harmonic ndeye zero sequence harmonics, ine hunhu hwekuungana mumutsara usina kwawakarerekera, zvichikonzera kudzvanyirira kwakanyanya pamutsetse usina kwawakarerekera, uye kunyangwe chiitiko chekupisa, icho chine njodzi huru dzakavanzwa mukuchengetedza kugadzirwa.Harmonics inogonawo kukonzera matunhu anotyora rwendo, kunonoka kugadzira nguva.Yechitatu harmonic inoumba kutenderera mu transformer uye inokurumidza kukwegura kweshanduro.Kusvibiswa kwakakomba kweharmonic kuchakanganisa kushanda kwesevhisi uye hupenyu hwemidziyo muhurongwa hwekugovera magetsi.
Mazhinji e inverter rectification link iko kushandiswa kwema 6 pulses kushandura AC kuita DC, saka maharmonics anogadzirwa anonyanya 5, 7, 11 nguva.Njodzi dzayo huru injodzi kumidziyo yemagetsi uye kutsauka mukuyera.Kushandiswa kweactive sefainogona kuva mhinduro yakanaka kudambudziko iri.
Kushandiswa kweinoshanda harmonicsefa:
1. Sefa kunze kwezvino harmonics, iyo inogona kunyatsosefa kunze kweharmonics ye2-25 nguva mumutoro wezvino, kuitira kuti iite network yekugovera yakachena uye inobudirira, uye inosangana nezvinodiwa zveyeyero yenyika yekugovera network clipping.Inoshanda sefa inonyatso inogadzirisa yekutevera muripo, inogona kuona otomatiki shanduko yemutoro uye kurodha harmonic shanduko yemukati uye nekukurumidza kuteedzera muripo, 80us mhinduro kurodha shanduko, 20ms kuwana yakazara yekutevera muripo.
2. Kuvandudza kusaenzana kwehurongwa, kunogona kubvisa zvachose kusaenzana kwehurongwa kunokonzerwa neharmonics, munyaya yezvibvumirano zvekushandisa, zvinogona kuiswa maererano nemushandisi kubhadhara hurongwa hunokosha husina kunaka kutevedzana uye zero kutevedzana kusaenzana kwezvikamu uye muripo wepakati pekugadzirisa simba rekuita.
3. Inhibisa resonance yemagetsi emagetsi, iyo isingazotauri nemagetsi emagetsi, uye inogona kunyatso kuenzanisa resonance yemagetsi emagetsi pachayo mukati mehuwandu hwehuwandu hwayo.
4. Mabasa akasiyana-siyana ekudzivirira, ane pamusoro pezvino, pamusoro pemagetsi, pasi pemhepo, kupisa kwepamusoro, kuyerwa kwedunhu, kurova kwemheni uye mamwe mabasa ekudzivirira.
5. Kushanda kwedhijitari yakazara, ine ushamwari man-machine interface, zvichiita kuti kushanda kuve nyore, nyore kushandisa nekuchengetedza.
