Introduction
In modern electrical systems, power quality issues such as harmonic distortion, voltage fluctuations, and reactive power imbalance pose significant challenges to system reliability and performance. Conventional passive filters are often limited in their ability to mitigate these issues effectively, especially in dynamic and nonlinear loads. The Hardware Implementation of Shunt Active Power Filter project addresses this limitation by proposing a hardware-based solution using shunt active power filters (SAPFs).
SAPFs are capable of dynamically compensating for harmonic currents, reactive power, and other disturbances in real-time, thereby improving power quality and system efficiency. By integrating SAPFs into the electrical network, the project aims to provide a reliable and cost-effective solution for mitigating power quality issues and ensuring stable operation of electrical equipment.
Problem
Power quality issues such as harmonic distortion, voltage fluctuations, and reactive power imbalance can have detrimental effects on electrical equipment and systems. Harmonic currents generated by nonlinear loads, such as power electronics and variable speed drives, can lead to overheating, increased losses, and reduced lifespan of equipment. Voltage fluctuations and reactive power imbalance can also cause voltage flicker, equipment malfunction, and instability in the electrical network.
Traditional methods of power quality correction, such as passive filters and capacitor banks, are often ineffective in addressing dynamic and nonlinear loads. Passive filters are limited in their ability to adapt to changing load conditions and may introduce resonance issues in the system. Capacitor banks can improve power factor but do not address harmonic distortion or voltage fluctuations.
Addressing these power quality issues requires the deployment of active filtering solutions capable of dynamically compensating for disturbances in real-time. Shunt active power filters (SAPFs) offer an effective and versatile solution for mitigating harmonic distortion, reactive power, and voltage fluctuations, thereby improving overall power quality and system reliability.
