Abstract

ABSTRACT:In order to solve power system distortions and instability, the project integrates technology from Thyristor-Controlled Reactors (TCR) and Shunt Hybrid Power Filters (SHPF). Our goal is to improve overall quality by balancing reliable power supply and disturbance filtering. Our objective is to develop a flexible reactive power control and noise filtering system that can be used in a variety of industrial and commercial contexts and is verified by simulations and tests.INTRODUCTION:In order to improve power quality, this study presents a combined approach that makes use of the technologies of Thyristor-Controlled Reactor (TCR) and Shunt Hybrid Power Filter (SHPF). Our goal is to increase dependability and efficiency by merging these. For harmonic and reactive power adjustment, the system combines a fifth-harmonic-tuned LC passive filter with a small-rating active power filter (APF). For TCR, proportional-integral control is used, and for SHPF, nonlinear control. The SHPF-TCR compensator is appropriate for a range of loads and power systems due to its effective reduction of distortions and reactive power compensation, as demonstrated by simulation and experimental findings.
