Abstract
This project proposes the hardware implementation of a Shunt Active Power Filter (SAPF) as a solution to mitigate power quality issues in electrical systems. SAPF is an advanced power electronic device used to compensate for harmonic distortion, reactive power, and unbalanced loads, thereby improving the overall power quality. This project aims to design, implement, and test a SAPF prototype to address power quality problems such as voltage harmonics, voltage flicker, and reactive power compensation in electrical networks.
Introduction
With the increasing use of nonlinear loads and renewable energy sources, power quality issues have become a significant concern in electrical systems. Harmonic distortion, voltage fluctuations, and reactive power imbalance can lead to equipment malfunction, reduced system efficiency, and increased energy costs. Shunt Active Power Filters (SAPFs) offer an effective solution to mitigate these power quality problems by dynamically compensating for harmonic currents and reactive power. This project seeks to design and implement a SAPF prototype to enhance the power quality of electrical systems.
Problem
Conventional power distribution systems are prone to power quality issues caused by nonlinear loads, unbalanced loads, and intermittent renewable energy sources. Harmonic currents generated by nonlinear loads can distort voltage waveforms and affect the performance of sensitive equipment. Reactive power imbalance can lead to voltage fluctuations and reduce the efficiency of power distribution networks. Addressing these power quality issues requires the deployment of advanced power electronic devices such as SAPFs. However, the design and implementation of SAPFs pose challenges related to cost, complexity, and compatibility with existing infrastructure.
Aim
The primary aim of this project is to design, implement, and test a Shunt Active Power Filter (SAPF) prototype to mitigate power quality issues in electrical systems. The SAPF prototype will be capable of compensating for harmonic distortion, reactive power, and unbalanced loads, thereby improving the overall power quality and reliability of electrical networks. The project aims to demonstrate the feasibility and effectiveness of SAPFs in real-world applications and provide insights into their practical implementation and performance.
