Ngokusekwe kumava amava omgangatho wamandla, xa sikhethaisihluzo esisebenzayo se-harmonic, iifomyula ezimbini ziqhele ukusetyenziswa ukuqikelela umthamo wokucinezelwa kwe-harmonic.
1. Ulawulo oluphakathi: Qikelela amandla okulungelelaniswa kolawulo oluhambelanayo olusekwe kulwahlulo lweshishini kunye namandla okuguqula.
S---- Umthamo olinganisiweyo weTransformer, U---- Umbane olinganisiweyo kwicala lesibini le-U-transformer
Ih---- iHarmonic yangoku, iTHDi----Itotali yomyinge wokuguqula ngoku, kunye noluhlu lwamaxabiso olugqitywe ngokusekelwe kumashishini ahlukeneyo okanye imithwalo.
K---- Umyinge womthwalo weTransformer
| Uhlobo lweshishini | Umyinge oqhelekileyo wokugqwethwa kwe-harmonic |
| Umzila ongaphantsi komhlaba, iitonela, oololiwe abahamba ngesantya esiphezulu, izikhululo zeenqwelomoya | 15% |
| Unxibelelwano, izakhiwo zorhwebo, iiBhanki | 20% |
| Ishishini lezonyango | 25% |
| Ukwenziwa kweemoto, ukwenziwa kweenqanawa | 30% |
| Chemical\Petroleum | 35% |
| Ishishini leMetallological | 40% |
2. Kwindawo yolawulo: Qikelela amandla olungiselelo lolawulo oluhambelanayo olusekwe kwiinkonzo zomthwalo ezahlukeneyo.
Ih---- Harmonic yangoku, THDi----Lilonke izinga langoku lokugqwetha, kunye noluhlu lwamaxabiso agqitywe ngokusekelwe kumashishini ahlukeneyo okanye imithwalo
K--- Umlinganiselo womthwalo weTransformer
| Uhlobo lomthwalo | Umxholo oqhelekileyo we-harmonic | Uhlobo lomthwalo | Umxholo oqhelekileyo we-harmonic |
| Inverter | 30---50 | Unikezelo lwamandla obushushu obuphakathi | 30---35 |
| I-elevator | 15---30 | Imithandathu yokuhlaziya i-pulse | 28---38 |
| Izibane ze-LED | 15---20 | Ishumi elinesibini le-pulse rectifier | 10---12 |
| Isibane sokugcina amandla | 15---30 | Umatshini wokuwelda wombane | 25---58 |
| Ibhola ye-elektroniki | 15---18 | Umoya womoya oguquguqukayo | 6----34 |
| Ukutshintsha unikezelo lwamandla kwimowudi | 20---30 | IUPS | 10---25 |
Qaphela: Ezi zibalo zingentla ziifomula zoqikelelo kuphela zereferensi.
Xa sikhethai-static var generator, iifomula ezimbini ziqhele ukusetyenziswa ukuqikelela umthamo wembuyekezo yamandla asebenzayo.
1.Uqikelelo olusekwe kumthamo wesiguquli:
I-20% ukuya kwi-40% yomthamo we-transformer isetyenziselwa ukuqwalasela umthamo wembuyekezo yamandla asebenzayo, kunye nokukhethwa ngokubanzi kwe-30%.
Q=30%*S
Q----Umthamo wembuyekezo yamandla asebenzayo, S----Umthamo wenguqu
Umzekelo, i-1000kVA i-transformer ixhotyiswe ngembuyekezo yamandla asebenzayo angama-300kvar.
2.Bala ngokusekelwe kumandla ombane kunye namandla asebenzayo esixhobo:
Ukuba kukho imilinganiselo yomthwalo eneenkcukacha, njengamandla aphezulu asebenzayo P, amandla factor COSO phambi kwembuyekezo, kunye nethagethi yamandla factor COSO emva kwembuyekezo, owona mthamo wembuyekezo ofunekayo kwinkqubo ingabalwa ngokuthe ngqo:
Q----Umthamo wembuyekezo yamandla asebenzayo, P----Amandla aphezulu asebenzayo
K----Umndilili womthwalo womlinganiso(uthathwa ngokubanzi njenge-0.7--0.8)
Qaphela: Ezi zibalo zingentla zenzelwe ireferensi kuphela.
I-Noker Electric izibophelele ekuboneleleni abathengi ngembuyekezo yamandla asebenzayo kunye nezisombululo zolawulo lwe-harmonic, nayiphi na imibuzo ekukhetheni imveliso, uziva ukhululekile ukuqhagamshelana nathi.
