A Comparative Study of Different Traveling Wave Fault Location Techniques
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 5
Abstract
Power transmission lines transfer a huge amount of electricity from generation stations to distribution centers. The flow of the large currents causes faults along transmission lines, leading to extended power outages and equipment failure. When a fault occurs along a line at a particular location, a reduction of voltage at that point leads to a high frequency inversion known as a traveling wave electromagnetic impulse. The velocity of propagation of the traveling wave along the line provides information about the fault. This study focuses on problems that cause a short circuit in a long-distance transmission line and develops a fault location method using traveling wave techniques. Single- and double-ended techniques are used to extract the voltage and the current traveling wave reflection and arrival times to locate the fault for three phases. The captured traveling wave signals input into MATLAB using a wavelet transform filter to obtain their frequency components. Four different techniques – two single-ended techniques (close in fault and remote end fault) and two double-ended techniques (close end and remote end) – are simulated on the IEEE 9-bus transmission system using MATLAB Simulink. This comparative study examines the application of different traveling wave techniques to find the most accurate technique for locating a transmission line fault.
