Kutengera zomwe zidachitika pamtundu wamagetsi, tikasankhayogwira harmonic fyuluta, njira ziwiri zimagwiritsidwa ntchito poyerekezera mphamvu ya kukakamiza kwa harmonic.
1.Ulamuliro wapakati: Yerekezerani momwe mungasinthire mphamvu za ulamuliro wa harmonic pogwiritsa ntchito gulu la makampani ndi mphamvu ya transformer.
S---- Mphamvu yovotera Transformer, U---- Voltage yovotera mbali yachiwiri ya U-transformer
Ih---- Harmonic current, THDi---- Chiwopsezo chonse chaposachedwa, chokhala ndi mitundu ingapo yotsimikizika kutengera mafakitale kapena katundu
K---- Transformer kuchuluka kwa katundu
| Mtundu wamakampani | Mlingo wodziwika bwino wa kusokoneza% |
| Subway, Tunnel, Masitima othamanga kwambiri, Mabwalo a ndege | 15% |
| Kulumikizana, nyumba zamalonda, Mabanki | 20% |
| Makampani azachipatala | 25% |
| Kupanga magalimoto, kupanga zombo | 30% |
| Chemical \Petroleum | 35% |
| Makampani opanga zitsulo | 40% |
2.Paulamuliro wamalo: Yerekezerani kuchuluka kwa kasinthidwe kaulamuliro wogwirizana kutengera ntchito zosiyanasiyana zonyamula katundu.
Ih---- Harmonic panopa, THDi----Zomwe zimasokonekera pakali pano, zokhala ndi milingo yosiyanasiyana yotsatiridwa ndi mafakitale kapena katundu wosiyanasiyana
K--- Transformer kuchuluka kwa katundu
| Mtundu wa katundu | Zomwe zili bwino% | Mtundu wa katundu | Zomwe zili bwino% |
| Inverter | 30--50 | Wapakati pafupipafupi induction kutenthetsa magetsi magetsi | 30---35 |
| Elevator | 15---30 | Six pulse rectifier | 28---38 |
| Magetsi a LED | 15---20 | 12 pulse rectifier | 10---12 |
| Nyali yopulumutsa mphamvu | 15---30 | Makina owotchera magetsi | 25--58 |
| Electronic Ballast | 15---18 | Kusintha pafupipafupi ma air conditioning | 6----34 |
| Kusintha mphamvu yamagetsi | 20---30 | UPS | 10---25 |
Zindikirani: Ziwerengero zomwe zili pamwambazi ndizongoyerekeza kuti zigwiritsidwe ntchito.
Tikasankhastatic var jenereta, njira ziwiri zimagwiritsidwa ntchito poyerekezera kuchuluka kwa chipukuta misozi champhamvu.
1.Kuyerekeza kutengera mphamvu ya thiransifoma:
20% mpaka 40% ya mphamvu ya thiransifoma imagwiritsidwa ntchito kukonza mphamvu zolipirira mphamvu, ndikusankha 30%.
Q=30%*S
Q---- Kuchuluka kwa chipukuta misozi, S---- Transformer mphamvu
Mwachitsanzo, thiransifoma ya 1000kVA imakhala ndi chipukuta misozi champhamvu cha 300kvar.
2.Kuwerengera kutengera mphamvu ndi mphamvu yogwira ntchito ya zida:
Ngati pali magawo atsatanetsatane a katundu, monga mphamvu yayikulu yogwira P, mphamvu ya COSO isanachitike chipukuta misozi, ndi chandamale champhamvu cha COSO pambuyo pa chipukuta misozi, mphamvu yeniyeni yolipirira yomwe imafunikira dongosolo ikhoza kuwerengedwa mwachindunji:
Q----Kuchuluka kwa chipukuta misozi, P---- Mphamvu yayikulu yogwira
K----Chiyerekezo cha katundu (nthawi zambiri chimatengedwa ngati 0.7--0.8)
Zindikirani: Mawerengedwe omwe ali pamwambawa ndi ongowona okha.
Noker Electric yadzipereka kupatsa makasitomala chipukuta misozi mwadongosolo komanso mayankho owongolera, mafunso aliwonse pakusankha kwazinthu, mumasuka kutilumikizana nafe.
