Harmonics musimba remagetsi rinobva kumidziyo yemagetsi, kureva, kubva pakugadzira michina uye zvigadzirwa zvemagetsi.
1.Harmonic source (iyo harmonic sosi pamagumo emagetsi kazhinji inonongedza kumidziyo yemagetsi inopinza harmonic ikozvino mugedhi reruzhinji kana kuti inogadzira harmonic voltage mugedhi yeruzhinji).Mimwe michina isina mutsara inoburitsa maharmonics paanoshanda mugridi.Semuenzaniso, single-phase rectifiers, electric arc furnaces, rectifiers, inverters, frequency converters, arc welding machines, induction heat equipment, electromechanical equipment ine magnetic saturation, etc. Harmonics inogadzirwa nemagetsi emagetsi, kunyanya rectifier thyristor equipment, inowanzoshandiswa mu emagetsi emagetsi, Lu electrolyzers, switching power requipment, nezvimwewo, uye ane akawanda maapplications.Yakawanda inogadzirisa thyristor midziyo inotora chikamu-shift control, saka inosiya yakawanda harmonics kune gidhi remagetsi.Zvinoenderana nehunyanzvi data statistics, iyo harmonics inogadzirwa neyakagadziridza mudziyo account ye40% yezvese harmonics, uye inowanzo zivikanwa seyo hombe sosi yeharmonics.Frequency shanduko yemidziyo inowanzo tora chikamu chekutonga, saka iyo inogadzirwa harmonics yakanyanya kuoma, kazhinji inosanganisira integer harmonics uye fractional harmonics.Nekuda kwesimba repamusoro reiyo frequency yekushandura michina, iyo harmonic yemukati inogadzirwa ichawedzerawo.Pamwe nemidziyo yemagetsi yemumba, nekuti mazhinji acho ane magetsi ekudzora nekugadzirisa, anozogadzira zvakadzika zvakakosha harmonics.Panguva imwecheteyo, kuchinja kwekusagadzikana kwemazuva ano kuchakonzerawo kuchinja kweiyo waveform.Nekuda kwehuwandu hukuru hwemidziyo yemumba, huwandu hwese hwema harmonics hunogadzirwa hwakakurawo.Vazhinji vavo vari kushandura magetsi emagetsi ekushandisa zvichienderana nemagetsi emagetsi zvikamu.
2. Iyo yekufambisa uye yekugovera sisitimu pachayo ichaitawo ma harmonics.Mhedzisiro huru yeharmonics ndiyo inoshandura simba.Nekuda kwekuzara kweiyo transformer core, iyo magnetizing ikozvino inoratidza peak waveform, kureva, isinganzwisisike harmonics.Iyo yakakwirira yekuzara kweiyo transformer core, iyo yakakura iyo harmonic ikozvino uye yakakwirira iyo harmonic yemukati inogadzirwa.Iyo ndeyesimbi yakakosha mudziyo ine ferromagnetic saturation maitiro.
3. Mhedzisiro yekugadzira magetsi yakaoma kuwana yakakwana yakakwana symmetry mune tekinoroji mumusangano uye kugadzirwa kwematatu-chikamu mhepo yejenareta seti, uye musimboti wesimbi pane jenareta haugone kunyatso yunifomu mumhando uye magadzirirwo, nezvimwe. zvichikonzera kunaka kwesimba rakagadzirwa.kwete yakakwirira, zvichiita kuti harmonics.
4. Gas discharge electric light source.Semuenzaniso, mwenje wefluorescent, mwenje we-high-pressure sodium, marambi esimbi halide, nezvimwewo, nekuda kwekusagadzikana kwavo kwakakomba, zvinokonzeresa kusinganzwisisike harmonic currents kune gidhi remagetsi.Iyo ndeyemidziyo ine arc senge yekushanda ine yakasimba nonlinear maitiro.
Kuti udzikise ma harmonics musimba remagetsi.Kazhinji, iyo pulse nhamba yemudziyo wekushandura inowedzerwa uye AC sefa inoiswa.Simbisa harmonic management.Iyo yakakwira uye yakaderera voltage reactive simba rekubhadhara mudziyo inogadzirwa neHongyan Electric, iyo yakakwira uye yakaderera voltage yakabatanidzwa capacitor muripo mudziyo uye yakakwira uye yakaderera voltage reactive simba rinoita uye static sefa yekubhadhara mudziyo zvese zvakavimbika zvakanyanya zvekudzikisa njodzi njodzi.
