Analysis and Simulation of Line Fault Location on High Voltage Transmission Line by Travelling Wave Principle
Phyu Phyu Win
Power System Protection is a vital importance for power engineers and is implicated by modern techniques with efficient and effective methods by traveling wave theory which is widely implied on high voltage theoretical background and practical application for line fault location and power system protection. An electric power system comprises of generation, transmission and distribution of electric energy. The rapid growth of electric power systems over the past few decades has resulted in a large increase of the number of lines in operation and their total length. These lines are exposed to faults as a result of lightning, short circuit, faulty equipments, mis-operation, human errors, overload and aging. The importance of this research arises from the need to reduce the interruptions of electricity, especially for interconnecting transmission lines and
to reduce the repair and restoration time especially in areas with difficult terrain. This can be attained by reducing the error in the fault distance estimation. In this paper, a travelling -wave scheme is used positive features of traveling wave algorithm. Validation of the fault location is performed using the Power System
Dynamics Monitoring System-Time Synchronizing (PSDM-TS) transient system. The algorithm will allow utilities to accurately locate line faults with the knowledge of transient current signals. Thus this paper provides an economic approach to fault location of transmission systems consistent with today's needs, providing a good foundation for further developments.
