Harmonics inokanganisa IT, kutaurirana / kubhengi masisitimu munzira mbiri: conduction uye radiation.Mamiriro ekutapurirana anoreva iyo harmonic yazvino yakaunzwa mumagetsi emagetsi system network ne pulse ikozvino masosi senge ma converter.Iyo radiation sosi mamiriro ndeyekuti harmonic currents anounzwa muhurongwa hwekutaurirana.Sezvataurwa pamusoro apa mune yakatarwa, "Chinangwa cheiyo yakatarwa ndechekudzikamisa iyo chaiyo harmonic voltage mumagetsi emagetsi system kusvika padanho (adaptive level) isingazokonzere zvinokuvadza pamidziyo yakaoma.Hunhu common harmonic mhedzisiro inonyanya kuve yeharmonics Pesvedzero yeave wave ikozvino uye hunhu impedance pane harmonic inoshanda voltage inokonzerwa neiyo transmission system software.
Kukuvadzwa kwemagetsi einjiniya maharmonics kune gidhi remagetsi kunoenderana nekukuvadza kweiyo harmonic inoshanda voltage kumakina nemidziyo iri mugidhi remagetsi, kureva kuti, iyo harmonic inoshanda voltage inodarika mwero ungatakurwa nemichina nemidziyo.Bato rekupa magetsi ndiro rinoita nezve pulse yazvino inoshanda voltage yemagetsi emagetsi network, uye mutengi wemagetsi ane basa rekuunza harmonic ikozvino yesoftware system.
Kuti uderedze kukuvadza kweharmonics kune magetsi uye kugovera sisitimu, zano rekutanga nderekutanga neiyo harmonic sosi, edza kudzivirira iyo harmonic ikozvino yakatenderedza iyo harmonic sosi, uyezve kuderedza harmonic voltage.Nzira yekudzivisa harmonic yazvino kukuvadza ndeyekuisa AC sefa, iyo inogona kudzora zvine musoro harmonic ikozvino, kuderedza kushanduka mukushanda kwemagetsi emagetsi emagetsi, nekuvandudza kunaka kwekufambisa uye kugovera simba.Mukuwedzera, inogona kushanduka kushandisa kushandiswa kwepamusoro kwemasimba emagetsi, uye hupenyu hwebasa hwakareba.Yakawedzerwa, iyo sefa inopa capacitive reactive mutoro, ine imwe reactive simba rekubhadhara mhedzisiro, nekudaro inovandudza iyo simba chinhu cheiyo system.Zvinoenderana nekuti iyo huru loop inosanganisira sosi yekushandisa, mafirita anogona kupatsanurwa kuita mafirita anoshanda uye passive mafirita.
Nemaitiro ekuvandudza tekinoroji yeruzivo, kutaurirana / bhizinesi rechikwereti, kuitira kuti isangane nezvinodiwa zvekushanda kwekamuri huru yekombuta yenzvimbo huru uye yepakati-kati data data, huwandu hwekushandisa hweHarmonic mitoro senge ups magetsi mumidziyo yekugovera magetsi. system software yeruzivo tekinoroji, kutaurirana / masangano emari akawedzera zvakanyanya.Mamiriro makuru eharmonic epasi-voltage simba rekugovera sisitimu yeruzivo tekinoroji, kutaurirana / masangano emari anosanganisira UPS magetsi, shanduko yemagetsi, frequency conversion air conditioner, etc. The harmonic ikozvino inogadzirwa nemidziyo yevagadziri vakasiyana-siyana inosiyana zvakanyanya, asi kazhinji yakakwirira.Kana iyo yakazara harmonic kukanganisa chiyero THDi yemazuva ano inodarika 50% (kazhinji pamusoro pe30%), iyo 5th, 7th, uye 11th harmonics Ikozvino yakaoma, dzimwe nguva ine zvinopfuura 3 harmonics.
Mushandisi Kukosha kweHarmonic Governance
Kuvandudza kuvimbika kwevatengi kutaurirana masisitimu uye simba rekugovera midziyo system software, wedzera hupenyu hwesevhisi yevatengi kutaurirana michina uye magetsi engineering;kunatsiridza kunaka kwekufambiswa kwezviratidzo zvedata rekutaurirana, kuve nechokwadi chese chakajairika kufambisa kwemasaini ekutaurirana data uye zviratidzo zvekushanda zvemidziyo yekutaurirana;kubvisa kuchinjika Njodzi dzekuchengetedza dzakadai sekuwandisa kwemidziyo yemagetsi, kupisa kwetambo dzemagetsi emagetsi, kudzikiswa kweazvino-yekutakura simba, uye voltage wave furemu kurasikirwa kunokonzerwa nekupomba kwemagetsi emidziyo yemagetsi senge UPS magetsi;kuwedzera simba rekushandisa kwepakati air-conditioning uye zvimwe midziyo mumba, uye kuvandudza hurongwa Simba rekushandisa software rinozadzisa chinangwa chekuchengetedza simba uye kuderedza kubuda.
Matambudziko aungasangana nawo?
1. Ikozvino reactive magetsi muripo wemidziyo haigone kushanda zvakajairika kana kazhinji inopisa;
2. Muzvirongwa zvekutaurirana, harmonics inovhiringidza maitiro ekukurukurirana ari pedyo.Iyo ruzha rushoma, iyo yakanyanya kunaka yekutaurirana, komputa haishande nemazvo, uye iyo inorema huremu, ruzivo rucharasika, zvichiita kuti system iparare.
3. Iyo yekudzivirira relay haisi kushanda kana kusashanda, iyo yemagetsi yekuyeresa chiridzwa haisi kuyera nemazvo, uye chaiyo zvigadzirwa zvemagetsi zvichakanganiswa zvakanyanya kana kukuvadzwa.
Mhinduro yedu:
1. Shandisa Hongyan passive sefa midziyo yekupa yakaderera-impedance chiteshi kune harmonics yeimwe frequency, uye bvisa harmonics kuti uwane mhedzisiro yeharmonic countermeasures uye reactive simba muripo.
2. Shandisa iyo inoshanda sefa Hongyan APF kubata maharmonics, uye iyo static kuchengetedza muripo wekushandisa kubhadhara reactive simba rehurongwa, kuitira kuti harmonic zvirimo uye simba chinhu chehurongwa zvigone kusangana nemaitiro ekambani yedu.
3. Iyo inoshanda sefa Hongyan APF inogamuchirwa, mazhinji emacapacitor eiyo inoshanda sefa anobvisa harmonic sefa, uye chikamu che capacitor chinotsiva iyo reactive simba, inovandudza simba rekuita, uye zvinobudirira kubata harmonics uye reactive simba rehurongwa. .
