Sefa Yogwira Ntchito Ya Harmonic (AHF) - Gawo Limodzi
Chidule cha malonda:
Zosefera za Active harmonic (AHF) ndiye yankho lomaliza ku zovuta zamtundu wamagetsi zomwe zimayambitsidwa ndi kusokonekera kwa ma waveform, kutsika kwamphamvu kwamagetsi, kusinthasintha kwamagetsi, kusinthasintha kwamagetsi komanso kusayenda bwino kwamagawo osiyanasiyana ndikugwiritsa ntchito.Ndiwo mawonekedwe apamwamba, ophatikizika, osinthika, osinthika komanso otsika mtengo a zosefera zamagetsi (APF) zomwe zimapereka kuyankha pompopompo komanso kothandiza kumavuto amtundu wamagetsi pamakina otsika kapena apamwamba kwambiri amagetsi amagetsi.Amathandizira kuti zida zanthawi yayitali zizikhala ndi moyo wautali, kudalirika kwazinthu zambiri, kuwongolera mphamvu zamakina ndi kukhazikika, ndikuchepetsa kutayika kwa mphamvu, kutsata miyezo yapamwamba yamagetsi ndi ma code a grid.
Ma AHF amachotsa kusokonekera kwa ma waveform pazambiri monga ma harmonics, ma interharmonics ndi notch, ndi ma voltages obwera chifukwa cha mafunde amtundu, pobaya munthawi yeniyeni mphamvu yopotoka ya kukula komweko koma mosiyana ndi gawo lamagetsi amagetsi.Kuphatikiza apo, ma AHF amatha kuthana ndi zovuta zina zingapo zamtundu wamagetsi pophatikiza ntchito zosiyanasiyana pachida chimodzi.
Mfundo Yogwirira Ntchito:
CT yakunja imazindikira katundu wapano, DSP monga CPU ili ndi masamu owongolera anzeru, imatha kutsatira malangizo apano, imagawanitsa katunduyo kukhala mphamvu yogwira komanso mphamvu yogwira ntchito pogwiritsa ntchito FFT yanzeru, ndikuwerengera zomwe zili mu harmonic mwachangu komanso molondola.Kenako imatumiza chizindikiro cha PWM ku board yamkati ya IGBT kuti muwongolere IGBT ndi kuyimitsa pafupipafupi 20KHZ.Pomaliza imatulutsa chipukuta misozi chosiyana pakusintha kwa inverter, nthawi yomweyo CT imazindikiranso zomwe zatuluka komanso zoyipa zomwe zimapita ku DSP.Kenako DSP imapitiliza kuwongolera kotsatira kuti ikwaniritse dongosolo lolondola komanso lokhazikika.
