Firita yeHarmonic Inoshanda (AHF)—Matanho Matatu
Pfupiso yeChigadzirwa:
Mafirita anoshanda (AHF) ndiwo mhinduro yekupedzisira kumatambudziko emhando yemagetsi anokonzerwa nekukanganiswa kwechimiro chemafungu, simba rakaderera, kusiyana kwemagetsi, kushanduka kwemagetsi uye kusaenzana kwemutoro kune zvikamu zvakasiyana-siyana uye mashandisirwo. Imhando yemafirita anoshanda (APF) anoshanda zvakanyanya, madiki, anochinjika, anochinjika uye anodhura zvishoma anopa mhinduro nekukurumidza uye inoshanda kumatambudziko emhando yemagetsi mumasisitimu emagetsi ane voltage shoma kana yakakwira. Anogonesa hupenyu hwemidziyo hurefu, kuvimbika kwakanyanya kwemaitiro, kugona kwesimba remagetsi kwakavandudzwa uye kugadzikana, uye kurasikirwa kwesimba kushoma, zvichitevedzera mitemo yemhando yemagetsi inoda simba uye makodhi egrid.
MaAHF anobvisa kukanganiswa kwechimiro chemagetsi kubva mumitoro yakaita seharmonics, interharmonics uye notching, uye harmonic voltages inokonzerwa neharmonic currents, nekuisa panguva chaiyo current yakakanganiswa yehukuru hwakafanana asi yakasiyana muchikamu musystem yemagetsi. Pamusoro pezvo, maAHF anogona kugadzirisa mamwe matambudziko akawanda emhando yemagetsi nekubatanidza mabasa akasiyana mumudziyo mumwe chete.
Nheyo yekushanda:
CT yekunze inoona load current, DSP sezvo CPU ine logic control arithmetic yepamusoro, inogona kukurumidza kuteedzera instruction current, inokamura load current kuita active power uye reactive power nekushandisa intelligent FFT, uye inoverenga harmonic content nekukurumidza uye nemazvo. Zvadaro inotumira PWM signal ku internal IGBT's driver board kuti idzore IGBT on and off pa20KHZ frequency. Pakupedzisira inogadzira opposite phase compensation current pa inverter induction, panguva imwe chete CT inoonawo output current uye negative feedback inoenda kuDSP. Zvadaro DSP inoenderera mberi ne logical control inotevera kuti iwane system yakarurama uye yakagadzikana.
