Product Description

DLAPF Series of Active Power Filter

Product Description

Brief introduction

APF is a kind of power electrical device. Its fundamental is to detect harmonic current from compensation object, then generate anti-harmonic compensation current, only leave the fundamental current in power system. APF device attracts a lot of attention. This device is an ideal device to prevent power grid "pollution" and improve power quality and save energy.

Application range

Following is the typical application range of APF:

  • Site with frequency converter
  • Site with imbalance loads
  • Steel company
  • Nonferrous metallurgy
  • Harbor machine
  • Electric railway
  • High precision automatic production line
  • CBD with energy saving lamp and air conditioners

Technical features

APF series active power filter reached international advanced technology level. It can meet city power grid reformrequirements. It provide standard 3 phase symmetry sine voltage compensates large capacity reactive power, harmonic current and negative-sequence current, lowers line loss.

  • Combine active power filter and passive power filter
  • DSP+FPGA all digital control system design
  • Using advanced compensation components separation method, quick DSP operation process, system trail time is approximately 20ms.
  • Equip perfect user interface, meets the requirements of local and remote control.
  • Automatic synchronization, no manual operation needed.
  • Modularized construction design, expandable capacity for user requirements.
  • Perfect protection function including overload, over voltage, under voltage, over current, temperature protection and self diagnosis.
  • Perfectly suitable for compensation of all harmonic, negative sequence and reactive power generated by various high-power non-linear load.
  • According to the requirements of reactive power compensation, harmonic compensation and negative sequence compensation, device can be uniformly set to multi-functional or single functional.

Technical Parametes

working principle

APF series active power filter is parallel with system, real-time monitoring the harmonic and reactive component of load, using PWM conversion technology, inject current, which is equile to the harmonic and reactive component in value, reversed in direction, to power distribution system and realize the functions of harmonic filteration and dynamic reactive compensation.

Figure 1 is schematic diagram of APF series parallel active power filter, APF can be called arbitrary wave generator, or controllable non-linear components. APF can compensate any harmonic current.
