Empirical Investigations: Power Quality Disturbance Classification

Abstract

In electrical power systems, one of the most essential parameters is a system signal with stable fundamental amplitude and frequency. Some disturbances have a negative impact on this stability, yet.These disturbances, known as power quality disturbances (PQDs), encompass phenomena such as sag, interruption, swell, harmonics, flicker, interharmonics, spike, notch, and transients. PQDs can ariseindividually or in some combinations. They pose unpredictable and variable effects on system componentsgiving rise to destructive outcomes. Acquisition of real-world datasets related to these disturbances is challenging due to the randomness and complex nature of power systems. Therefore, the importance of conducting experimental studies to investigate and analyze PQDs has significantly increased. This study aims to serve as a valuable resource for researchers investigating PQDs. It provides a guidance, offering insights into some types of PQDs and their characteristics. This paper supports researchers in understanding and addressing the challenges based on PQDs by presenting knowledge about these disturbances and their impacts. Recognizing the significance of experimental studies, the compilation includes methodologies, experimental setups, and tools employed for studying PQDs. It emphasizes the necessity for experimental datasets to enhance research in this field and highlights the importance of PQD investigation.
