Firita yeHarmonic Inoshanda (AHF)

Hurongwa hweKudzora Harmonic Hwemhando Yepamusoro

- Kuderedza kurongeka kweharmonic kwechipiri kusvika ku50

- Muripo wenguva chaiyo

- Dhizaini yemodular

- Dzivirira michina kuti isanyanya kupisa kana kutadza kushanda

- Kuvandudza kushanda zvakanaka kwemidziyo

Verenga zvakawanda

Kushanda zvakanaka kwazvo kwekusefa
Dhizaini yemodular
Nzira dzakawanda dzekubhadhara
Shandisa zvikamu zvepamusoro-soro
Yakachengeteka uye yakavimbika

Firita yeHarmonic Inoshanda (AHF) Firita yeharmonic inoshanda rudzi rwechishandiso chemagetsi chinoshandiswa kuderedza kana kubvisa kukanganiswa kweharmonic mumasisitimu emagetsi. Kukanganiswa kweHarmonic kunoreva kuvapo kwemafrequencies asingadiwe musisitimu yemagetsi izvo zvinogona kukonzera matambudziko akadai sekuwedzera kupisa kwemidziyo, kudzikira kwekushanda zvakanaka kwesisitimu, uye kunyange kutadza kushanda kwemidziyo.

AHF inoshanda nekuona ma "harmonic currents" ari musystem uye kugadzira "counter-current" ine hukuru hwakafanana uye chikamu chakapesana. Iyi "counter-current" inodzima "harmonic current" uye inoidzivirira kuti isadzoserwe musystem yemagetsi. Ma "Active harmonic filters" akagadzirwa kuti akurumidze uye akarurama mukupindura kwawo kune mamiriro e "harmonic" ari kuchinja musystem yemagetsi. Ma "Active harmonic filters" anowanzo shandiswa munzvimbo dzemaindasitiri nedzemabhizinesi uko kune mazinga akakwira e "non linear loads", akadai se "variable frequency drives", "uninterruptible power supplies", uye michina yemakomputa. Anoshandiswawo mukuvandudza mhando yemagetsi muzvivakwa zvekugara nezvemabhizinesi.

Nheyo yekushanda

Firita yeHarmonic Inoshanda (AHF)

Nekunge load current yaonekwa ne external CT, DSP seCPU ine advanced logic control arithmetic, inogona kukurumidza kuteedzera instruction current, kupatsanura load current kuita active power uye reactive power nekushandisa intelligent FFT, uye kuverenga harmonic content nekukurumidza uye nemazvo. Zvadaro inotumira PWM signal ku internal IGBT's driver board kuti idzore IGBT on and off pa 20KHZ frequency. Pakupedzisira, inogadzira opposite phase compensation current pa inverter induction. Panguva iyi, CT inoonawo output current uye negative feedback inoenda kuDSP. Zvadaro DSP inoenderera mberi ne logical control inotevera kuti iwane system yakarurama uye yakagadzikana.
