50A harmonic reduction convenient 33kv harmonic filters

Dynamically compensate 2-50 times all harmonics or specific harmonics Reduce harmonic to less than 5% What Is Harmonic? A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency,. i.e. if the fundamental frequency is 50Hz, the frequencies of the next harmonics are: 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 100 Hz (4th harmonic) etc. Main nonlinear load includes: UPS Switching power supply Rectifier Frequency inverter Frequency adjustable air conditioner Inductive heating furnace Electronic computer Charger Main harmonics polluting industries:
Product Description Product Function: 33kv harmonic filters is a new electronic harmonic filtering device to reduce voltage harmonic and current harominic and improve power quality. Based on voltage source inverter, it’s connected in parallel with non-linear loads which need to compensate. For compensating harmonic current which is with changing Amp and frequency and reactive power, it overcomes the shortcomings of traditional passive filter. It has the advantages of high compensation accuracy and fast dynamic response etc. APF adopts innovative intelligent control algorithm, through space vector modulation technology, generates compensation current with equal value and opposite direction to harmonics and reactive power and puts it into electric network and achieves harmonic suppression and reactive power dynamic compensation. 150A multilevel active harmonic filter Main Technical Parameters

Summary: Beijing Green Power active filter general performance is better than Europe brand. The items with red color is better performance. Active harmonic filter other features Have user-friendly operating software for easy operation. Could withstand load short circuit shock, and restart after removal of short circuit. Automatically eliminate resonance, not affected by electric network impedance and system impedance change. Could simultaneously filter 2-50 harmonics in three-phase four -line distribution system, and is able to choose compensation or not for each harmonic from 2-50 harmonics . The system has fast and complete fault self detection features, including undervoltage or overvoltage , overcurrent, fan failure , power devices over temperature , input fuse failure etc. fault self detection, all fault could be alarmed by APF and automatically taken corresponding actions. APF’s high-frequency carrier itself can not be feedback to electric network. Overcompensation must be avoided during filtering, i.e. APF could realize only filtering without generating reactive power to avoid over compensation completely, or by setting target power factor, the remaining energy after filtering is used for reactive power compensation. Have soft start control loop to avoid too large inrush current while starting and to limit the current within rated range. When the system is powered down, the filter could be automatically disconnected; After system recovery, the filter can be automatically restored.
