ABSTRACT
This paper offers an assessment of the performance of an active filter (AF) with three phases and four wires. The suggested three-phase four-wire AF utilizes a split-capacitor configuration. It employs instantaneous active and reactive power theory to create the reference current as well as an adaptive hysteresis current controller to produce the switching signal. The assessment centers on the AF's capability to rectify existing current harmonic distortion and current imbalance in a three-phase four-wire configuration. All assessments were performed in line with IEEE 519-2022 and IEEE 1159-2019, which deal with current harmonic distortion and current imbalance in electrical systems. According to IEEE 519-2022, current harmonic distortion is analyzed using total demand distortion, with thresholds set by the calculated ISC/IL ratio, a method not often addressed in other studies. Another important contribution of this paper is the application of IEEE 1159 as the standard for current imbalance, as limited research has assessed compensation performance for current imbalance with this standard. The assessment outcomes indicate that the AF introduced in this paper performs exceptionally in concurrently addressing current imbalance and current harmonics within a three-phase system with four wires.
