Active Harmonic Sefa (AHF)—Single Phase
Product Summary:
Active harmonic mafirita (AHF) ndiyo yekupedzisira mhinduro kumatambudziko emhando yemagetsi anokonzerwa nekukanganiswa kwewaveform, yakaderera simba chinhu, kusiyanisa kwevoltage, kushanduka kwevoltage uye kusaenzana kwekuremerwa kwezvikamu zvakasiyana uye mashandisirwo.Iwo emhando yepamusoro, compact, inochinjika, modular uye inodhura-inoshanda mhando yeanoshanda magetsi mafirita (APF) ayo anopa mhinduro pakarepo uye inoshanda kumatambudziko emhando yemagetsi mune yakaderera kana yakakwira voltage emagetsi masisitimu.Vanogonesa hupenyu hurefu hwemidziyo, kuvimbika kwepamusoro, kuvandudzwa kwesimba system uye kugadzikana, uye kuderera kurasikirwa kwesimba, kuenderana neakanyanya kudiwa emhando yemagetsi uye makodhi makodhi.
AHFs inobvisa kukanganiswa kwemasaveform kubva pamitoro senge harmonics, inter harmonics uye notching, uye harmonic voltages anokonzerwa neharmonic currents, nekupinza munguva chaiyo-chaiyo yakakanganiswa yehukuru hwakafanana asi yakapesana muchikamu mumagetsi emagetsi system.Uye zvakare, maAHF anogona kutarisira akati wandei mamwe matambudziko emhando yemagetsi nekubatanidza mabasa akasiyana mumudziyo mumwe.
Working Principle:
External CT inoona mutoro wazvino, DSP seCPU ine advanced logic control arithmetic, inogona kukurumidza kuteedzera rairo yazvino, kupatsanura mutoro wazvino kuita simba rinoshanda uye reactive simba nekushandisa yakangwara FFT, uye inoverengera harmonic zvirimo nekukurumidza uye nemazvo.Zvadaro inotumira chiratidzo chePWM kune yemukati IGBT yedhiraivha bhodhi kudzora IGBT nekudzima pa20KHZ frequency.Pakupedzisira inogadzira yakatarisana nechikamu chekubhadhara ikozvino pane inverter induction, panguva imwe chete CT inoonawo yakabuda ikozvino uye yakaipa mhinduro inoenda kuDSP.Ipapo DSP inoenderera mberi inotevera inonzwisisika kutonga kuti iwane yakanyatsojeka uye yakagadzikana sisitimu.
