3 Power Quality Monitoring and Management System

1) ANAPF Active Power Filter

1.) Working principle

ANAPF series active power filters are connected in parallel in a low-voltage power distribution system with harmonic loads, enabling fast and real-time tracking and compensation of dynamically changing harmonic currents. The principle is: ANAPF series active power filter collects harmonic current through CT, and quickly calculates and extracts the content of each harmonic current through the controller, generates harmonic current command, and generates and harmonics current amplitude through power execution device. The compensation currents, which are equal in direction, are injected into the power system to cancel out the harmonic currents generated by the non-linear loads.

2) ANSVC low-voltage reactive power compensation device

2.1) Working principle

The ANSVC low-voltage reactive power compensation device is connected in parallel in the entire power supply system, and can control power capacitor switching to compensate according to changes in the load power factor in the power grid. The principle is: ANSVC low-voltage reactive power compensation device through the CT acquisition of current and voltage signals, calculated by the reactive power compensation controller, to calculate a better program for switching capacitors, through non-contact switches to control switching power capacitors in each group.
