HTAF active power filter

Product Description

Operation principle HTAF active power filter is mainly consisted of instruction current arithmetic circuit and compensation current generating circuit. Instruction current arithmetic circuit monitors current in line on real time, changes analog current signal into digital signal, deals signal in DSP, divides harmonic and fundamental wave, sends drive pulse to impregnated current generating circuit in PWM form, drives IGBT or IPM power module, produces current with opposite polarity and same amplitude of compensating current and sends current into electrified wire netting, compensates or counteracts harmonic current and cancels electric harmonic actively. In this way, harmonic current is dealt actively, quickly and completely. HTAF active power filter can supply required fundamental reactive compensating current, achieves dynamic reactive compensation and improves power factor of electrified wire netting. HTAF Series Active Power Filter Characteristic 1. Parallel access, install and maintain easily 2. Filter 2nd to *0th harmonic wave 3. Filter more than *5% harmonic wave 4. Filter wave automatically, never affected by impedance in electrified wire netting 5. Dynamic real-time track-compensation, quick response 6. Filter effect is not affected by electrified wire netting resistance 7. Inhibit overload automatically, no resonance danger 8. No upper frequency ripples current interference 9. Multi-module parallel operation *0. Compensate harmonic and reactive power simultaneously *1. High efficient filter, low electric energy loss *2. Multi-protection to ensure system operate safely and reliably *3. Digital control, Chinese language LCD *4. Fault self-diagnostic function, history recording function *5. RS**5 interface, standard MODBUS communication agreement
