ʻO Harmonics i ka ʻōnaehana mana mai nā lako uila, ʻo ia hoʻi, mai ka hana ʻana i nā mea hana a me nā lako uila.
1. Kumu Harmonic (ke kumu harmonic ma ka hopena o ka mana e kuhikuhi ana i nā mea uila e hoʻokomo i ka au i loko o ka pā lehulehu a i ʻole e hoʻohua i ka voluma harmonic i ka pā lehulehu).Hoʻopuka kekahi mau mea laina laina ʻole i ka harmonics ke hana lākou i ka pā.No ka laʻana, hoʻokahi-phase rectifiers, uila arc furnaces, rectifiers, inverters, frequency converters, arc welding machines, induction heating equipment, electromechanical equipment with magnetic saturation, etc. nā locomotives uila, Lu electrolyzers, hoʻololi i nā lako mana, a me nā mea ʻē aʻe, a loaʻa kahi ākea o nā noi.ʻO ka hapa nui o nā mea hoʻoponopono thyristor e hoʻohana i ka mana o ka hoʻololi ʻana, no laila e waiho i ka nui o nā harmonics i ka pā mana.Wahi a nā helu ʻikepili ʻenehana, ʻo ka harmonics i hana ʻia e ka mea hoʻoponopono hoʻoponopono helu no 40% o nā harmonics āpau, a ʻike pinepine ʻia ʻo ia ke kumu nui o nā harmonics.Hoʻohana maʻamau nā mea hoʻololi pinepine i ka mana phase, no laila ʻoi aku ka paʻakikī o nā harmonics i hana ʻia, maʻamau me nā harmonic integer a me nā harmonic fractional.Ma muli o ka mana kiʻekiʻe o ka mīkini hoʻololi pinepine, e hoʻonui ʻia ka ʻike harmonic i hana ʻia.A me nā lako uila o ka hale, no ka mea, ʻo ka hapa nui o lākou he mau mea hoʻoponopono uila a hoʻoponopono, e hana pū lākou i nā harmonic kumu hohonu.I ka manawa like, ʻo ka hoʻololi ʻana o ke au kaulike ʻole e hoʻololi i ka ʻano nalu.Ma muli o ka nui o nā mea hana hale, nui loa ka nui o nā harmonics i hana ʻia.ʻO ka hapa nui o lākou ke hoʻololi nei i nā lako lako mana e pili ana i nā ʻāpana uila.
2. Na ka ʻōnaehana hoʻoili a me ka hāʻawi ʻana iā ia iho e hana i nā harmonics.ʻO ke kumu nui o nā harmonics ka mea hoʻololi mana.Ma muli o ka saturation o ka mea transformer core, e hōʻike ana ka magnetizing current i kahi ʻano nalu kiʻekiʻe, ʻo ia hoʻi, nā harmonic odd.ʻOi aku ka kiʻekiʻe o ka saturation o ka mea transformer core, ʻoi aku ka nui o ka manawa harmonic a ʻoi aku ka kiʻekiʻe o ka ʻike harmonic i hana ʻia.Aia ia i ka mea hao nui me nā hiʻohiʻona saturation ferromagnetic.
3. He mea paʻakikī ke kumu o ka mana e hoʻokō i ka symmetry maikaʻi loa i ka ʻenehana i ka hui a me ka hana ʻana o ka wili ʻekolu-phase o ka generator set, a ʻaʻole hiki i ke kumu hao ma luna o ka mea hana ke hoʻohui like ʻole i ka maikaʻi a me ke ʻano, etc. ka hopena i ka maikaʻi o ka mana i hana ʻia.ʻaʻole kiʻekiʻe, e hopena i nā harmonics.
4. Hoʻokuʻu kinoea kumu kukui uila.No ka laʻana, nā kukui fluorescent, nā kukui sodium kiʻekiʻe, nā kukui halide metala, a me nā mea ʻē aʻe, ma muli o ko lākou nonlinearity koʻikoʻi, e hoʻoulu pū i nā au harmonic ʻē aʻe i ka pā mana.Aia ia i nā mea hana me ka arc ma ke ʻano he mea hana me nā ʻano nonlinear ikaika.
I mea e kaupalena ai i nā harmonics i ka ʻōnaehana mana.ʻO ka maʻamau, hoʻonui ʻia ka helu pulse o ka mea hoʻololi a hoʻokomo ʻia kahi kānana AC.E hoʻoikaika i ka hoʻokele harmonic.ʻO ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa reactive mana uku uku i hana ʻia e Hongyan Electric, ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa i hoʻohui ʻia i ka capacitor compensation device a me ka kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa reactive power dynamic a me static filter compensation device he mau mea hilinaʻi loa ia no ka hōʻemi ʻana i nā pōʻino harmonic.
