General

Acrel power quality device is mainly used for power supply and distribution equipment at the user end, and provides power quality improvement equipment (such as active filters, reactive power compensation equipment, etc.) to help improve user power quality and make users more economical, safe and reliable.

Acrel ANAPF series active power filter collects the harmonic current of the system through the current transformer, quickly calculates and extracts the content of each harmonic current by the controller, generates the harmonic current command, and generates an amplitude equal to the harmonic current through the power executive device. Compensating currents in opposite directions are injected into the power system to cancel harmonic currents generated by non-linear loads.

ANAPF is connected in a low-voltage distribution system with harmonic loads in parallel, which has the ability to realize fast and real-time tracking and compensation of dynamically changing harmonic currents. Mainly used in hospitals, commercial plazas, manufacturing, data centers, charging piles, airports, photovoltaic and other industries.

Function

1) Flexible compensation method: Compensating for reactive power from the load, filter out harmonics within 5th, 7th, 9th, 11th, and 13th;

2) Ability of managing three-phase imbalance;

3) Linear compensation, Response time ≤ 5ms;

4) Humanized human-computer interaction interface, which displays real-time power quality information of the system and the ontology. This interface has the ability to control the device remotely and easy to operate;

5) Adopt imported IGBT which has high power density and high reliability;

6) Using DSP digital control system for high speed detection and calculation;

7) With remote communication interface, real-time monitoring through PC;

8) Standard modular design which reduces lead times and increases reliability and maintainability.
