Product Description

Wt-bpqc compensated power quality regulator is an integrated comprehensive power quality regulator that can simultaneously compensate power quality problems such as voltage, harmonic, reactive power and imbalance. The device is composed of automatic voltage regulation compensation module, reactive power and harmonic compensation module. The automatic voltage regulation compensation module compares the over voltage and under voltage with the reference setting voltage by actually monitoring the grid voltage, and generates a voltage equal to the difference voltage and in the opposite direction, which is superimposed on the line voltage to ensure stable output voltage.  

 The reactive power and harmonic compensation module compensates the line reactive power and harmonic according to sampling calculation of the system voltage and current. Through multi-objective coordinated control, it can be realized: 1. Voltage regulation; 2. Active and reactive power dynamic regulation; 3. Harmonic filtering; 4. Three-phase imbalance control.
