IDENTIFICATION AND CLASSIFICATION OF DISTURBANCES ON HV TRANSMISSION SYSTEMS

Availability of electrical power has much more importance than before and there is no tolerance to power interrupts in today's power networks. There are many different types of transient disturbances and short duration variations affecting the safe operation of sub-components such as high voltage transmission lines, underground power cables, switching equipment, etc. It is necessary to identify and classify those in a very short time in order to provide high speed clearance of the disturbance by taking necessary action such as isolating the faulty line section to enable fast restoration. Therefore, it is needed to develop an algorithm and analyzing scheme that can be used on-line monitoring serving for identification of transient events and their classification by defining the possible…
