Abstract


The modern power system frequently encounters power quality (PQ) disturbances that require careful analysis and effective mitigation strategies. These disturbances arise from various underlying causes, making it crucial to identify the specific source for accurate mitigation. This paper focuses on the generation and analysis of voltage sag disturbances, which are among the most common PQ issues in power systems. Through both simulation and experimental approaches, this study replicates voltage sag conditions caused by different factors, including transformer energization, induction motor starting, line faults, and load variations. MATLAB Simulink models are used to simulate these scenarios, while a tailor-made experimental setup is employed to validate the simulation results. By integrating simulation and experimental data, this study offers a comprehensive understanding of PQ disturbances, supporting the development of enhanced system designs and operational practices.
