ANALYSIS OF ELECTRICITY SUPPLY IN THE DISTRIBUTION NETWORK OF POWER SECTOR

Nowadays, consumers of electricity are demanding for better quality of services and this creates competition in power utility companies to provide better services which are reliable as well as efficient and less costly also to their consumers. Assessment of PQ problems is a tedious task and the various aspects of power system and equipment modelling, disturbance mitigation and data analysis are involved in it. The majority of the work is focused on the distribution system where the sensitive equipments experience interference under different kinds of power disturbances from the system and the local network. For the effective mitigation of these disturbances, some knowledge about PQ events and its effects on equipment is important. So, in this concern PQ is a challenging issue in current scenario. The main aim of this review paper is to investigate different techniques reported by the researchers for detection and classification of PQ events.
