Isihlungi Se-Noker Active Harmonic Sifakwe Esibhedlela

I-harmonic esebenzayo ukuhlungaisibe yingxenye ebalulekile yemikhiqizo yekhwalithi yamandla ekhiqizwa ezimbonini nasezindaweni zezohwebo.Amandla asebenzayoizihlungikubalulekile ukunciphisa ama-harmonics nokugcina ukusebenza kahle kwezinhlelo zikagesi.Ikakhulukazi, izihlungi ze-harmonic ezisebenzayo zezigaba ezintathu zingasiza ekunciphiseni izinkinga zekhwalithi yamandla ezibhedlela.Izibhedlela zidinga amasistimu kagesi ekhwalithi ephezulu ukusekela okokusebenza kwezokwelapha kanye nokugcina ukusebenza okubalulekile empilweni.Amasistimu kagesi wasesibhedlela angaba nohide lweziphazamiso, okuhlanganisa amadiphu, ukuvuvukala, ama-voltage transients, kanye nokuphazamiseka kazibuthe.Ama-harmonics akhiqizwa okokusebenza kwe-elekthronikhi angaphazamisa ikhwalithi yamandla esibhedlela futhi abangele ukulimala kwemishini, okuholela ekuhlulekeni kwesistimu nokuncipha kokunakekelwa kwesiguli.Izihlungi ze-harmonic ezisebenzayo ziyizingxenye ezibalulekile ezisiza ukugcina ikhwalithi yamandla ezibhedlela.Lobu buchwepheshe buhlala buqapha ukuhlanekezelwa kwe-harmonic futhi buhlunga lezo zimpawu ezingafuneki ngaphambi kokuthi zilimaze isistimu.Izihlungi ezisebenzayo ze-harmonic zilungisa ukuhlanekezela kwe-waveform futhi zinikeze amandla ekhwalithi ephezulu ezikhungweni zesibhedlela ngokuhlanganisa ubuchwepheshe obufana nama-capacitor, ama-inductors, nezingxenye ezisebenzayo.Izihlungi ezisebenzayo ze-harmonic ziklanyelwe ukusebenza ngokuhambisana nesekhethi ye-mains ngenkathi yethula okwamanje okwengeziwe ohlelweni.Lokhu kwamanje kusiza ukukhiqiza ama-harmonics alingana ngama-amplitude kodwa aphikisana nesigaba kulabo abakhona ohlelweni lukagesi, ngaleyo ndlela kunciphisa kakhulu ama-harmonics.I-waveform yamanje ehlungiwe esebenzayo ibekwe phezulu kufomethi yegagasi yamanje engahlungiwe ukuze yakhe i-waveform enengqikithi ephansi yokuhlanekezela kwe-harmonic.Ucwaningo lwakamuva lubonisa ukuthi izihlungi ze-harmonic ezisebenzayo zisetshenziswe kanjani ngempumelelo ezibhedlela.Isibhedlela esinemibhede engu-300 e-China besinezinkinga zekhwalithi yamandla ngenxa yokuhlanekezelwa okuhambisanayo okukhiqizwa imishini kagesi ebanzi efakwe ngaphakathi kwesikhungo.Lokhu kuhlanekezela kudlula kakhulu amazinga amukelekayo, okwenza izintambo nama-transformer ashise ngokweqile, afinyeze ukuphila kwemishini futhi abangele ukugcinwa nokushintshwa njalo.Isibhedlela sifake i-100Aisihlungi esisebenzayo se-harmonic sesigaba sesithathuukudambisa lezi zinkinga.Idivayisi inciphisa ukuhlanekezela okuphelele kwe-harmonic (THD) isuka ku-16% iye ngaphansi kuka-5%.Isihlungi esisebenzayo siphinda sinyuse isici samandla sisuke ku-0.86 siye ekuvaleni koku-1, sinciphise ukusetshenziswa kwamandla ohlelweni.Izihlungi ezisebenzayo ze-harmonic zandisa ukusebenza kahle kwezinhlelo zikagesi futhi zandisa ukwethembeka kwesistimu ngokuvimbela ukwehluleka kwemishini, zonga izibhedlela isikhathi esibalulekile sokugcinwa kanye nemali.Ngokufigqiwe,izihlungi ze-harmonic ezisebenzayoinikeza izinzuzo ezibalulekile ekugcineni ikhwalithi yamandla ezibhedlela.Imishini kagesi eya ngokuya isetshenziswa ezibhedlela, futhi ama-harmonics abawakhiqizayo angabangela izinkinga ezinkulu zekhwalithi yamandla.Izihlungi ezisebenzayo ze-harmonic ziyingxenye ebalulekile yemikhiqizo yekhwalithi yamandla ehlunga ukuhlanekezela okungafunwa futhi inikeze amandla ekhwalithi ephezulu ezikhungweni zesibhedlela.Izihlungi ezisebenzayo ze-harmonic zinganciphisa ukusetshenziswa kwamandla, zinciphise umzamo wokulungisa, futhi ekugcineni zisize izibhedlela zinikeze ukunakekelwa kwesiguli kwekhwalithi ephezulu.
