Ma Harmonics amakhudza IT, kulumikizana / mabanki machitidwe m'njira ziwiri: conduction ndi radiation.Kupatsirana kumatanthawuza za ma harmonic apano omwe amalowetsedwa mu netiweki yamagetsi ndi magwero apano monga otembenuza.Zomwe zimayambira ma radiation ndikuti mafunde a harmonic amalowetsedwa munjira yolumikizirana.Monga tafotokozera pamwambapa, "Cholinga chazomwezi ndikuchepetsa mphamvu yeniyeni yamagetsi mumagetsi opangira magetsi kuti ifike pamlingo (mulingo wosinthika) womwe sudzabweretsa zotsatira zoyipa pazida zovutirapo.Zotsatira zodziwika bwino za anthu zimangotengera ma harmonics Chikoka cha mafunde apano komanso mawonekedwe amphamvu pamagetsi opangira ma harmonic omwe amayamba chifukwa cha pulogalamu yotumizira.
Kuwonongeka kwa ma harmonics opangira magetsi ku gridi yamagetsi kumadalira kuwonongeka kwa mphamvu yamagetsi yogwirira ntchito pamakina ndi zida mu gridi yamagetsi, ndiye kuti, mphamvu yamagetsi yogwirira ntchito imaposa mlingo womwe makina ndi zida zimatha kupirira.Gulu lamagetsi limayang'anira mphamvu yamagetsi yomwe ikugwira ntchito pamagetsi amagetsi, ndipo wogwiritsa ntchito magetsi ali ndi udindo woyambitsa pulogalamu ya pulogalamuyo.
Pofuna kuchepetsa kuvulaza kwa ma harmonics ku magetsi ndi kugawa dongosolo, lingaliro lofunikira ndiloyamba ndi gwero la harmonic, yesetsani kupewa mphamvu yamagetsi yozungulira gwero la harmonic, ndiyeno muchepetse mphamvu ya harmonic.Njira yopewera kuwonongeka kwapano ndikuyika fyuluta ya AC, yomwe imatha kuletsa kusinthasintha kwapano, kuchepetsa kusinthasintha kwamagetsi ogwiritsira ntchito magetsi a gridi yamagetsi, ndikuwongolera kufalikira kwamagetsi ndikugawa.Kuphatikiza apo, imatha kugwiritsa ntchito mphamvu zambiri zonyamula mphamvu, ndipo moyo wautumiki ndi wautali.Kuwonjeza, fyulutayo imapereka capacitive zotakasika katundu, amene ali ena zotakasika mphamvu chipukuta misozi zotsatira, potero kusintha mphamvu factor ya dongosolo.Malinga ngati kuzungulira kwakukulu kumaphatikizapo zida zoyambira, zosefera zitha kugawidwa kukhala zosefera zogwira ntchito ndi zosefera zopanda pake.
Ndi kakulidwe kaukadaulo wazidziwitso, kulumikizana / bizinesi yangongole, kuti akwaniritse zofunikira za chipinda chachikulu chapakompyuta cha malo akulu ndi apakatikati, kuchuluka kwa ntchito zolemetsa monga kukweza magetsi pazida zogawa magetsi. pulogalamu yamapulogalamu aukadaulo wazidziwitso, kulumikizana / mabungwe azachuma awonjezeka kwambiri.Magwero akuluakulu a harmonic a otsika-voltage mphamvu yogawa mphamvu yaukadaulo wazidziwitso, kulumikizana / mabungwe azachuma akuphatikizapo magetsi a UPS, osinthira mphamvu, owongolera pafupipafupi, ndi zina zotere. Zomwe zili pano za harmonic zomwe zimapangidwa ndi zida za opanga osiyanasiyana zimasiyana kwambiri, koma nthawi zambiri imakhala yokwera.Pamene chiwerengero chonse cha kupotoza kwa harmonic THDi chamakono chimaposa 50% (nthawi zambiri pamwamba pa 30%), 5th, 7th, ndi 11th harmonics Pakali pano ndi yovuta, nthawi zina imakhala ndi ma harmonics oposa 3.
Mtengo Wogwiritsa Ntchito Harmonic Governance
Kupititsa patsogolo kudalirika kwa njira zoyankhulirana ndi makasitomala ndi pulogalamu yamagetsi yogawa zida zamagetsi, kuwonjezera moyo wautumiki wa zida zoyankhulirana ndi makasitomala ndi zomangamanga zamagetsi;kupititsa patsogolo kufalikira kwa ma sigino a data yolumikizirana, kuwonetsetsa kufalikira kwanthawi zonse kwa ma siginecha olumikizirana ndi zizindikiro za magwiridwe antchito a zida zoyankhulirana;Kuchotsa zoopsa zosiyanasiyana zachitetezo monga kutenthedwa kwa zida zamagetsi, kutenthedwa kwa zingwe zamagetsi, kuchepetsa mphamvu zonyamula pakali pano, komanso kuwonongeka kwa mawonekedwe amagetsi obwera chifukwa cha mafunde amagetsi amagetsi monga magetsi a UPS;kuwonjezera mphamvu yogwiritsira ntchito mpweya wapakati ndi zipangizo zina m'nyumba, ndikuwongolera dongosolo Mphamvu ya pulogalamuyo imakwaniritsa cholinga chopulumutsa mphamvu ndi kuchepetsa umuna.
Mavuto omwe mungakumane nawo?
1. Zipangizo zamakono zolipirira mphamvu zamagetsi sizingagwire ntchito bwino kapena zimayaka;
2. Mu machitidwe oyankhulana, ma harmonics amasokoneza njira zoyankhulirana zoyandikana.Phokoso likachepa, kulumikizana koyipa kwambiri, kompyuta siyigwira ntchito bwino, komanso kulemera kwake, chidziwitsocho chimatayika, ndikupangitsa kuti dongosololi liwonongeke.
3. Njira yodzitchinjiriza sikugwira ntchito kapena kulephera, chida choyezera chamagetsi sichikuyezetsa molondola, ndipo zinthu zamagetsi zolondola zidzakhudzidwa kwambiri kapena kuonongeka.
Yankho lathu:
1. Gwiritsani ntchito zida zosefera za Hongyan kuti mupereke njira yochepetsera mphamvu ya ma harmonics pafupipafupi, ndikuchotsa ma harmonics kuti mukwaniritse zotsatira za kuyeserera kwamphamvu komanso kubweza mphamvu zotakataka.
2. Ntchito yogwira fyuluta Hongyan APF kusamalira harmonics, ndi malo amodzi chitetezo chipukuta misozi chipangizo kubweza zotakataka mphamvu ya dongosolo, kuti harmonic zili ndi mphamvu chinthu cha dongosolo akhoza kukumana mfundo za kampani yathu.
3. The yogwira fyuluta Hongyan APF anatengera, ambiri capacitors wa fyuluta yogwira kuchotsa harmonic fyuluta, ndi mbali ya capacitor compensation ndi zotakasika mphamvu, bwino chinthu mphamvu, ndi bwino amasamalira harmonics ndi zotakasika mphamvu ya dongosolo. .
