HYAPF mndandanda nduna yogwira fyuluta

Kufotokozera Kwachidule:

Zofunika

Fyuluta yamagetsi yogwira imalumikizidwa ndi gululi yamagetsi mofananira, ndipo voteji ndi zomwe zili pachiwopsezo zimadziwika mu nthawi yeniyeni, yowerengedwa ndi gawo la opareshoni yapano, ndipo gawo lapansi la IGB limayendetsedwa ndi kugunda kwamagulu ambiri. ukadaulo wosinthira ma siginali.Lowetsani zamakono ndi gawo losiyana ndi ukulu wofanana ndi mphamvu yamagetsi ya gridi ku gululi, ndipo mafunde awiri a ma harmonic amangoletsana wina ndi mzake, kuti akwaniritse ntchito zosefera ma harmonics ndi kubwezera mphamvu zowonongeka, ndikupeza ankafuna magetsi panopa.

Pakadali pano, zinthu zazikuluzikulu zimagawidwa m'magulu awiri: zinthu zowongolera za harmonic ndi zowongolera zamagetsi.Mafakitale omwe amakhudzidwa: fodya, mafuta, magetsi, nsalu, zitsulo, zitsulo, zoyendera njanji, mafakitale apulasitiki, mankhwala, kulumikizana, malo opangira ma photovoltaic, Municipal, nyumba ndi mafakitale ena, zotsatirazi ndizochitika zingapo.
1. Makampani opanga nsalu: Zinthu zazikuluzikulu ndi UPS zazikulu komanso zida zamakompyuta.UPS imapatsa katunduyo mphamvu yamagetsi yapamwamba kwambiri yokhala ndi kukhazikika kwamphamvu kwamagetsi komanso kupotoza kwa mawonekedwe otsika.Komabe, popeza UPS ndi katundu wosagwirizana, wokonzanso mu UPS amapanga kuchuluka kwa ma harmonic current , kotero kuti kusokonezeka kwaposachedwa pamagulu a gululi ndipamwamba kwambiri, zomwe sizimangoyambitsa kuwonongeka kwa gridi, komanso kumakhudza kwambiri. kulowetsedwa kwabwino kwa kabati yogwira ntchito, ndikuwongolera kwa harmonic kuyenera kuchitika
2. M'makampani opangira madzi, injini ya mpope yolowera madzi imayendetsedwa ndi otembenuza ma frequency amphamvu kwambiri.Popeza osinthira pafupipafupi amafunikira kukonzanso ma diode amphamvu kwambiri komanso inverter yamphamvu kwambiri ya thyristor, chifukwa chake, ma harmonics amakono amapangidwa m'magawo olowera ndi otulutsa, omwe amasokoneza dongosolo lamagetsi.Katundu ndi zida zina zamagetsi zoyandikana nazo zimakhudza magwiridwe antchito amtundu wa metering, ndipo kuwongolera kwa harmonic kuyenera kuchitika.
3. Makampani a fodya: Katundu wake ndi “chingwe chopunthira”.“Chingwe chopunthira” ndiko kusefa zonyansa za masamba a fodya kuti tipeze masamba a fodya opanda zodetsa.Izi zimachitika kudzera mu converter pafupipafupi ndi ma motors.The frequency converter ndi gwero lalikulu kwambiri la harmonic, chifukwa chake limabweretsa kuyipitsa kwakukulu komanso kusokoneza kwa ma harmonic ku dongosolo, ndipo kuwongolera kwa harmonic kuyenera kuchitika.
4. Makampani opanga makina olankhulana: UPS yakhala chida chofunikira kwambiri muchipinda cha makompyuta, UPS imatha kupereka katundu
Mphamvu yamagetsi yapamwamba kwambiri yokhazikika yokhazikika, ma frequency okhazikika, ndi kupotoza kwa mawonekedwe otsika, ndipo imatha kupeza mphamvu yosasokoneza mukasintha ndi static bypass.Komabe, popeza UPS ndi katundu wopanda mzere, ipanga kuchuluka kwa ma harmonics apano.Ngakhale gridi yamagetsi imayambitsa kuipitsa kwa harmonic, imakhudzanso zida zina zapakompyuta, zomwe zimapangitsa kusokoneza kwakukulu kapena kuvulaza njira yolumikizirana.Chifukwa chake, zipinda zonse zamakompyuta zolumikizirana ziyenera kukumana ndi vuto la kuwongolera kwa harmonic.
5. Sitima yapamtunda: Pofuna kuyankha kuyitanidwa kwa dziko kuti apulumutse mphamvu ndi kuchepetsa kugwiritsira ntchito mphamvu, kampani yapansi panthaka inaganiza zogwiritsa ntchito ma inverters mumayendedwe a njanji kuti asinthe mphamvu zopulumutsa mphamvu, ndipo panthawi imodzimodziyo azichita ulamuliro wa harmonic pa ma inverters.Pambuyo pa nthawi ya kafukufuku, kuti akwaniritse bwino ntchito yokonzanso mphamvu yopulumutsa mphamvu, gululo linaganiza zoyendetsa polojekiti ya Rail Transit Line 4. Pakati pawo, wosinthira pafupipafupi amasankhidwa kuchokera kuzinthu za Schneider Co., Ltd. ., ndipo fyuluta yamagetsi yogwira ntchito imasankhidwa kuchokera ku Xi'an Xichi Power Technology Co., Ltd.
6. Chitsulo chachitsulo: Chifukwa cha zofunikira zopanga, zida zomwe zili kumbali yachiwiri ya thiransifoma mu njira yogawa mphamvu yamagetsi otsika kwambiri ndi injini, ndipo makina osinthira pafupipafupi amayendetsa galimoto kuti agwire ntchito.Popeza mawonekedwe amkati a otembenuza pafupipafupi amagwiritsa ntchito zigawo zambiri zopanda malire, ma harmonics ambiri amapangidwa panthawi yogwira ntchito.Pali zina zimakhudza katundu pa akugubuduza ndondomeko mbale, ndi kupanga ndondomeko si mosalekeza, zomwe zimayambitsa kusinthasintha ndi discontinuities mu ntchito voteji / panopa, ndi kusintha pa ntchito panopa komanso kuchititsa harmonic panopa kusinthasintha.
