الملخص

High Voltage transmission lines are designed to transfer large amount of power from one location to another. The length exposed to the environment is a major reason for occurrence of faults on the lines. A fault on a high voltage transmission line affects the stability of the overall power system, which sometimes leads to permanent damage of the equipment. The Major problem of tripping signal of a relay based on steady state component does not warranty faster tripping schemes for protection of high voltage transmission lines. Proposed work has made an attempt to find solution to the problem of fault detection and faster tripping using numerical relay based on travelling wave.Voltage and current traveling waves are generated when a fault occurs on the transmission line. The Information about the fault can be obtained by analyzing the traveling waves. This Thesis has made an attempt to obtain travelling waves components in the form of forward wave and backward waves from post fault components of voltage and current. The traveling wave techniques, which are based on analog signal processing, proposed in this thesis in addition to numeric techniques identify and locate the fault by using the information contained in the waves. The techniques are implemented in MATLABSIMULINK. Some cases of the fault are discussed in the thesis.The performance of the numeric technique for protecting HV transmission lines using traveling waves is confirmed to be satisfactory. The proposed technique provide protection at speed and accurate.
