Abstract :
A novel device based on power electronic is presented, designed to help in voltage regulation on the secondary feeder of distribution transformers, to help to mitigate the sag and swell phenomena, and for canceling harmonic voltages. The device is based in the injection of a series voltage with that of the own transformer. Such voltage is created by means of a voltage source converter (VSC) and controlled through a digital signal processor (DSP). Results obtained in a laboratory prototype and by simulation exhibit its applicability
