PROJECT TITLE :

Experimental Investigation on a Hybrid Series Active Power Compensator to Improve Power Quality of Typical Households - 2016

ABSTRACT:

In this paper, a transformerless hybrid series active filter employing a sliding-mode control algorithm and a notch harmonic detection technique are implemented on a single-phase distribution feeder. This methodology provides compensation for source current harmonics coming back from a voltage fed type of nonlinear load (VSC) and reactive power regulation of a residential shopper. The realized active power filter enhances the power quality whereas cleaning the point of common coupling (PCC) from possible voltage distortions, sags, and swells initiated through the grid. Furthermore, to beat drawbacks of real-time control delay, a computational delay compensation method, that accurately generates reference voltages, is proposed. Based on an improved compensation strategy, whereas the grid current remains clean even with a tiny compensation gain, voltage disturbances initiated by the power system are obstructed by the compensator, and therefore the PCC became free of voltage harmonics and protected against sag and swell. Simulation and experimental results carried on a 1.6-kVA prototype are presented and mentioned.
