Kuongororwa kwesimba remaharmoniki mumagetsi

Manyuko eharmonics

Kune zvikonzero zvakawanda zvekugadzirwa kwemaharmoniki, saka kune masosi akawanda, uye mhando dzemidziyo inoshandiswa dzinoratidzawo hunhu hwakasiyana-siyana. Pakati pazvo, masosi makuru emaharmoniki anosanganisira mapoka etransformer mugrid yemagetsi, maovheni emagetsi eindasitiri, zvishandiso zvemagetsi zvemagetsi zvechikamu chimwe chete, uye michina yakasiyana-siyana ye rectifier uye michina inodzora voltage yeAC.

Kuongorora kunokuvadza kwemaharmoniki

Kuvapo kwemaharmoniki musimba remagetsi kwakaenzana nekwakabva kusvibiswa kwesimba remagetsi, uye chinhu chinosvibisa chinonyanya kukonzera nharaunda yemagetsi musimba remagetsi. Sechikamu chakakosha chezvakatipoteredza chesimba remagetsi, nharaunda yemagetsi inoratidza njodzi dzakasiyana pasi pesimba remaharmoniki akasiyana. Zvisinei, kukuvadza uku kushoma kuchaderedzawo kushanda zvakanaka kwemidziyo yemagetsi, uye mhedzisiro yakakomba inogona kutungamira mukutambudzwa kwekushanda kwakasimba uye kwakachengeteka kwesimba remagetsi uye kukuvara kwemidziyo yemagetsi. Kukuvadzwa kwekugadzirwa kwemaharmoniki kunosanganisira zvinhu zvinotevera:

(1) Midziyo yemagetsi iri kupisa zvisina kujairika kana ikaitwa nemaharmonics, uye kurasikirwa kwakawedzerwa kwakakura zvakanyanya. Kunyangwe paine mukaha mukuru pakati pehuwandu hweharmonic current ne fundamental current, kuvapo kwemaharmonics kuchawedzera simba reganda remudziyo, uye kuramba kunoshanda kuchawedzera mukuita kwekuona mhedzisiro yeganda. Kune mimwe michina yakakosha, kurasikirwa kukuru kwe eddy current uye kurasikirwa kwe hysteresis zvichaitikawo, senge michina yemagetsi ine iron cores. Kana waveform ikakanganiswa kusvika pamwero wakati, wave hombe ye amplitude peak inowedzera simba rekubuda kwechikamu. Pasi pemamiriro ezvinhu akadaro ekushandisa zvakanyanya, zviri nyore kuderedza hupenyu hwebasa remidziyo yemagetsi.

(2) Mota inogona kukonzera kudedera kwemuchina. Pasi pesimba remagetsi anotenderera, simba remagineti rinotenderera remota rinoburitsa torque inoputika inogona kukonzera kuti mota idedera. Pasi pesimba remafrequency emuchina, rudzi urwu rwekudedera runogona kukonzera kudedera kwemuchina kunokuvadza, nokudaro zvichiisa panjodzi mhando yemidziyo yemagetsi uye kutotyisidzira hupenyu hwevanhu.

(3) Kukanganisa michina yemakombiyuta nezvimwe zvishandiso zvekudzora otomatiki. Mumamiriro ezvinhu akajairwa, michina yekudzora otomatiki nedzimwe nzira dzekudzora otomatiki dzakabatana dzakagadzirirwa zvichibva pamagetsi akajairika uye voltage yakatakura. Kana maharmonics agadzirwa, system yekudzora otomatiki haifungi nezvechinhu ichi chinopesvedzera, zvichiita kuti zvive nyore Kukanganisa kunokanganisa mashandiro ebasa rayo rekudzora. Kana huwandu hwekusvibiswa kwemaharmonics hwakakura, zvinokwanisikawo kushandura maitiro ekushanda kwesystem yekudzora otomatiki, zvichiita kuti ibudise gwara risiri iro. Rudzi urwu rwekukanganisa ruchakanganisa zvakanyanya kugadzirwa chaiko uye mashandiro, uye kunyange kukonzera tsaona dzekuchengetedza dzisingadzoreki.
