Dongosolo lamagetsi loyendera njanji limagwiritsa ntchito mayunitsi okonzanso kuti apereke mphamvu ya DC ku ma EMU, kotero ma harmonics sangalephereke.Zinthu za harmonic zikapitilira muyeso wina, zitha kuwononga mphamvu zamatawuni.Komanso, kuunikira, UPS, zikepe makamaka kubala 3, 5, 7, 11, 13 ndi harmonics ena.Ndipo mphamvu yonyamula katundu ndi yayikulu, ndipo mphamvu yogwira ntchito ndi yayikulunso.

Ma Harmonics amachititsa kuti chitetezo cha relay ndi zida zodziwikiratu zamagetsi ziwonongeke kapena kukana kugwira ntchito, zomwe zimayika pachiwopsezo chachitetezo cha gridi yamagetsi;imayambitsa zida zamagetsi zosiyanasiyana kuti zipangitse kutaya ndi kutentha kwina, ndikupangitsa injini kupanga kugwedezeka kwamakina ndi phokoso.Mphamvu ya harmonic ili mu gridi yamagetsi.ngati mtundu wa mphamvu, pamapeto pake idzagwiritsidwa ntchito pamizere ndi zida zosiyanasiyana zamagetsi, potero zikuwonjezera kutayika, mphamvu zochulukirapo komanso ma harmonics, zomwe zimapangitsa kuwonongeka kwa thiransifoma komanso kuchepa kwa magwiridwe antchito, ndikuphatikizidwa ndi mbali yamagetsi yamagetsi, zomwe zimapangitsa kuti zikhale zazikulu. - zovuta zamtundu wamagetsi.

Zipangizo zoyatsira, UPS, mafani, ndi zikepe zimapanga mafunde amphamvu, zomwe zimapangitsa kuti magetsi asokonezeke.Panthawi imodzimodziyo, mafunde a harmonic adzaphatikizidwa ku mbali yamphamvu kwambiri kudzera mu transformer.Chosefera chogwira (HYAPF) chikakhazikitsidwa, fyulutayo ipanga chipukuta misozi ndi matalikidwe omwewo koma ma angles osiyana ndi ma harmonics omwe apezeka.Gridi yamagetsi imachotsedwa ndi ma harmonics olemetsa kuti akwaniritse cholinga chosefa ndi kuyeretsa gridi yamagetsi, yomwe imatha kuchepetsa kulephera kwa zida.Zosefera zamagetsi zogwira ntchito zimakhala ndi ntchito yabwinoko kuposa zosefera zachikale, zimatha kubweza zofananira, ndipo sizimakonda kumveka bwino.
