APFM Active power filter (APF)

        The active power filter (APF) is mainly composed of controller, isolation switch (circuit breaker), contactor, IGBT, driving circuit, protection system, fuse, connection reactor, DC capacitor, etc. The controller measures phase A, C reactive power(current), produces control signal, drives IGBT on/off and produces harmonic and reactive current same as system harmonic current but in opposite phase to filter system harmonic, reduce reactive power and keep system power factor approximately at 1. Our APF equipment is module structure,there are two types Wall Mounted and cabient mounted.The Wall Mounted type is preferred to be used in equipment improvement which is very convenient to install.

Introduction

  • The active power filter (APF) is mainly composed of controller, isolation switch (circuit breaker), contactor, IGBT, driving circuit, protection system, fuse, connection reactor, DC capacitor, etc. The controller measures phase A, C reactive power(current), produces control signal, drives IGBT on/off and produces harmonic and reactive current same as system harmonic current but in opposite phase to filter system harmonic, reduce reactive power and keep system power factor approximately at 1.
  • Our APF equipment is module structure,there are two types Wall Mounted and cabient mounted.The Wall Mounted type is preferred to be used in equipment improvement which is very convenient to install.
  • It is suitable for any non-linar loads like:
  • softstarter
  • UPS,Inverter,EV charger etc
  • Lift,welding machine,control motor
  • Electronics data handle,IDC
  • Lights

Feature

  • Compact and reasonable structure, flexible installation.
  • Advanced control algorithm, software reliability.
  • Double DSP control system, using vector screening technology.
  • Dynamic filter 2 to 50 harmonics, may optionally specified harmonic filter.
  • Harmonic compensation, reactive power compensation and three-phase unbalance compensation.
  • Various capacity module, arbitrary combination and capacity expansion machine, good performance, to meet the different needs of the system capacity.
  • Standard communication interface and communication protocol.
  • Fault alarm and recording function, can be as much as 500 alarm records.
  • With all kinds of complete and effective protection measures, such as over-voltage protection, under voltage protection, short circuit protection, inverter bridge reverse protection, compensation protection etc.
  • Load change process, if the resonance, APFM self judgment and exit system, at the same time, alarm, and avoid.
