Ama-Harmonics ohlelweni lwamandla avela ezintweni zikagesi, okusho ukuthi, kusukela kumishini ekhiqizayo nemishini kagesi.
1.Umthombo we-Harmonic (umthombo we-harmonic ekupheleni kokunikezwa kwamandla ngokuvamile ukhomba okokusebenza kukagesi okujova i-harmonic current kugridi yomphakathi noma okhiqiza amandla kagesi e-harmonic kugridi yomphakathi).Amanye amadivayisi angaqondile azokhiqiza ama-harmonics lapho esebenza kugridi.Isibonelo, izilungisi zesigaba esisodwa, izifutho zikagesi ze-arc, izilungisi, iziguquli, iziguquli zefrikhwensi, imishini yokushisela i-arc, okokusebenza kokushisisa, okokusebenza kwe-electromechanical nokugcwaliswa kazibuthe, njll. Ama-Harmonics akhiqizwa okokusebenza kagesi, ikakhulukazi okokusebenza kwe-thyristor, asetshenziswa kakhulu izitimela zikagesi, ama-Lu electrolyzers, izinsiza zamandla ezishintshayo, njll., futhi zinezinhlelo eziningi ezahlukene.Imishini eminingi ye-thyristor ye-rectifier isebenzisa ukulawulwa kwe-phase-shift, ngakho-ke izoshiya ama-harmonics amaningi kugridi yamandla.Ngokwezibalo zedatha yobuchwepheshe, ama-harmonics akhiqizwa idivayisi yokulungisa ahlanganisa u-40% wawo wonke ama-harmonics, futhi ngokuvamile akhonjwa njengomthombo omkhulu kakhulu wama-harmonics.Izinto zokusebenza zokuguqula imvamisa ngokuvamile zisebenzisa ukulawulwa kwesigaba, ngakho-ke ama-harmonics akhiqizwayo ayinkimbinkimbi kakhulu, ngokuvamile ahlanganisa ama-harmonics aphelele kanye nama-harmonics angama-fractional.Ngenxa yamandla aphezulu wemishini yokuguqula imvamisa, okuqukethwe kwe-harmonic okukhiqiziwe nakho kuzokwanda.Kanye nemishini kagesi yasendlini, ngenxa yokuthi iningi lazo linamadivaysi alawula amandla kagesi kanye nokulungisa, zizophinde zikhiqize ama-harmonics ajulile ayisisekelo.Ngesikhathi esifanayo, ukuguqulwa kwamandla angalingani kuzophinde kubangele ukuguqulwa kwe-waveform.Ngenxa yenani elikhulu lemishini yasendlini, inani eliphelele lama-harmonics akhiqizwayo nalo likhulu kakhulu.Iningi labo lishintsha imishini yokuphakelwa kukagesi ngokusekelwe ezingxenyeni zamandla kagesi.
2. Uhlelo lokudlulisa nokusabalalisa ngokwalo luzophinde lukhiqize ama-harmonics.Umthombo oyinhloko wama-harmonics yi-transformer yamandla.Ngenxa yokugcwala kwe-transformer core, i-magnetizing current izobonisa i-waveform ephakeme kakhulu, okungukuthi, ama-harmonics angavamile.Ukuphakama kwe-saturation ye-transformer core, i-harmonic yamanje inkulu futhi iphakeme okuqukethwe kwe-harmonic okukhiqizwayo.Kungokwedivayisi ewumgogodla wensimbi enezici ze-ferromagnetic saturation.
3. Umthombo wokuphehla amandla kunzima ukufeza ukulinganisa okuphelele okuphelele kwezobuchwepheshe ekuhlanganiseni nasekukhiqizeni ukuphenduka kwezigaba ezintathu zesethi ye-generator, futhi umgogodla wensimbi ku-generator awukwazi ukufana ngokuphelele ngekhwalithi nokuthungwa, njll. okuholela kwikhwalithi yamandla akhiqiziwe.hhayi phezulu, okuholela kuma-harmonics.
4. Umthombo wokukhanya kagesi okhipha igesi.Isibonelo, izibani ze-fluorescent, izibani ze-sodium ezicindezela kakhulu, izibani zensimbi ze-halide, njll., ngenxa yokungahambisani kwazo okujulile, zizophinde zibangele imisinga ye-harmonic eyinqaba kugridi yamandla.Okokusebenza okune-arc njengesisetshenziswa esisebenzayo esinezici eziqinile ezingaqondile.
Ukuze unciphise ama-harmonics ohlelweni lwamandla.Ngokuvamile, inombolo ye-pulse yedivayisi yokuguqula iyakhuphuka futhi kufakwe isihlungi se-AC.Qinisa ukuphathwa kwe-harmonic.Idivayisi yesinxephezelo samandla kagesi aphezulu naphansi ekhiqizwa i-Hongyan Electric, idivayisi yesinxephezelo samandla kagesi aphezulu naphansi edidiyelwe kanye nedivayisi yesinxephezelo samandla ashukumisayo ashukumisayo nesihlungi esimile konke okunokwethenjelwa kakhulu kokunciphisa izingozi ezihambisanayo.
