Parallel Active Power Filter With Predictive Structure For Reference Current Determination - Experimental System

Abstract

For the purpose of experimental verification of the simulation results of the three-phase active filter with predictive determination of the reference current, its laboratory model was made. The paper presents a functional description of a laboratory model of a three-phase active filter. The power circuit of the active filter consists of three single-phase chokes, a three-phase inverter with IGBTs and two symmetrical capacitors on the DC side. Current regulation is realized using three independent hysteresis regulators. A filter system algorithm with a predictive structure for determining the reference current was developed and implemented on a DSP. The experimental results of the realized three-phase active filter in stationary and dynamic modes of operation are presented. The obtained experimental results confirm the effectiveness of the active energy filter in weakening the higher harmonics of the current in the network.
