Inkqubo yokuhanjiswa kwamandla kaloliwe isebenzisa iiyunithi zokulungisa ukunika amandla eDC kwii-EMUs, ngoko ke iiharmonics azinakuthintelwa.Xa umxholo we-harmonic udlula uluhlu oluthile, unokubangela ingozi kwinkqubo yamandla asezidolophini.Ukongeza, ukukhanya, i-UPS, izinyusi zivelisa ikakhulu i-3, 5, 7, 11, 13 kunye nezinye iiharmonics.Kwaye amandla omthwalo makhulu, kwaye amandla asebenzayo makhulu nawo.

I-Harmonics ibangela ukukhuselwa kwe-relay kunye nezixhobo ezizenzekelayo zenkqubo yamandla ukuba zingasebenzi okanye zinqabe ukusebenza, ezibeka engozini ngokuthe ngqo ukusebenza okukhuselekileyo kwegridi yamandla;ibangela izixhobo zombane ezahlukeneyo ukuba zivelise ilahleko eyongezelelweyo kunye nobushushu, kwaye ibangela ukuba imoto ivelise ukungcangcazela koomatshini kunye nengxolo.I-harmonic yangoku ikwigridi yamandla.njengohlobo lwamandla, aya kuthi ekugqibeleni asetyenziswe kwimigca kunye nezixhobo ezahlukeneyo zombane, ngaloo ndlela kwandisa ilahleko, amandla asebenzayo ngokugqithisileyo kunye ne-harmonics, okukhokelela ekulahlekeni kwelahleko ye-transformer kunye nokunciphisa ukusebenza kakuhle, kwaye iya kudityaniswa necala le-voltage ephezulu, ebangela ngaphezulu Okukhulu. -ingxaki zomgangatho wamandla.

Izixhobo zokukhanyisa, i-UPS, iifeni, kunye nezinyusi zivelisa imisinga ye-harmonic, ebangela ukuphazamiseka kwamandla ombane.Ngexesha elifanayo, i-harmonic currents iya kudibaniswa necala eliphezulu le-voltage ngokusebenzisa i-transformer.Emva kokuba isihluzo esisebenzayo (HYAPF) sifakiwe, isihluzi siya kuvelisa imbuyekezo yangoku kunye ne-amplitude efanayo kodwa i-engile yesigaba esichaseneyo kwii-harmonics ezichongiweyo.Igridi yamandla ihlanjululwa kunye ne-harmonics yomthwalo ukufezekisa injongo yokucoca kunye nokucoca igridi yamandla, enokunciphisa ngokufanelekileyo izinga lokungaphumeleli kwezixhobo.Izihluzi zamandla asebenzayo zinentsebenzo engcono kunezihluzo zesiqhelo zokwenziwa, zinokubuyekeza ngokuguqukayo iiharmonics, kwaye azityekelekanga kwiresonance.
