Power Quality Improvement and Harmonics Compensation Using Hybrid Filter

Abstract

The need for electricity is expanding at an even faster rate in these modern times. In order for the electrical devices to function properly and effectively, a constant supply of high-quality power is required. The most common types of power quality reducing factors include noise, interruptions, variations in voltage and frequency, and so on. These factors all contribute to a decrease in the electrical devices' overall efficiency. Total harmonic distortion (THD) was made worse by the presence of non-linear loads. The existence of harmonics is the primary cause of the problems that lead to the breakdown of insulation, excess heating, and a shortened lifespan for various pieces of equipment. In addition to this, if there is a high THD in the electrical system, it may cause the energy meter to give inaccurate readings. An economic hybrid filter can be employed to reduce the losses caused by harmonics distortion, thereby providing a solution to those issues. This paper provides an in-depth look into the application of this filter for harmonic compensation. By performing simulations with the Simulink tool of MATLAB and validating the results using the experimental setup, it has been determined that using a filter can reduce the total harmonic distortion (THD) of the current by 40.09 percentage points, which will result in better power quality and energy conservation. The IEEE Standard 519-1992 was consulted as a reference when making this determination.
