Review: Investigation & Mitigation of Power Quality Events

Chetan E. Morkhade, Chetan M. Bobade

Abstract :

 Development of electrical power supplies began more than one hundred years ago. At the beginning, there were only small DC networks within narrow local boundaries, which were able to cover the direct needs of industrial plants by means of hydro energy. With an increasing demand on energy and the construction of large generation units, typically built at remote location from the load centers, the technology changed from DC to AC. Power to be transmitted, voltage levels and transmission distances increased. Power quality (PQ) issue has attained considerable attention in the last one and half decade due to large penetration of power electronics based loads and/or microprocessor based controlled loads. On one hand these devices introduce power quality problem and on other hand these mal–operate due to the induced power quality problems. PQ disturbances/events cover a oad frequency range with significantly different magnitude variations and can be non–stationary, thus, accurate techniques are required to identify, classify and mitigate these events/disturbances.            This paper presents a comprehensive overview of different techniques used for PQ event’s classifications and mitigations. Various artificial intelligent techniques which are used in PQ event classification are also discussed. Major Key issues and challenges in classifying PQ events are critically examined and outlined.
