Abstract: Voltage
sag and swell are significant power quality disturbances that can adversely
affect sensitive industrial, commercial, and residential loads. These
disturbances may lead to equipment malfunction, production losses, and reduced
operational efficiency. This paper presents a novel approach for voltage sag
and swell mitigation using an FPGA (Field-Programmable Gate Array)
controller-based Unified Power Quality Conditioner (UPQC). The UPQC consists of
series and parallel compensating devices, enabling the system to simultaneously
correct both voltage sags/swells and current harmonics, thus ensuring the
reliability and quality of power supply. The proposed system's key feature is
the utilization of FPGA technology for real-time control, which improves response
time, enhances processing efficiency, and reduces hardware complexity. The main
objective to develop this method is Development of an FPGA-based UPQC system,
Real-time voltage sag and swell compensation, Evaluation of system performance.
Simulation results demonstrate the effectiveness of the system in mitigating
voltage disturbances, providing a robust solution to power quality issues. The
future scope of this research includes Power Electronics Optimization, Fault
Detection and Diagnostics, Wireless Communication and IoT Integration etc.
