Step Fault: This is a fault system consisting of a number of faults with parallel fault planes, the separated blocks slipping in the same direction along parallel planes giving a step-like feature. The fault inception also involves in insulation failures and conducting path failures which results short circuit and open circuit of conductors. In the analysis of power system under fault conditions, it is necessary to make a distinction between the types of fault to ensure the best results possible in the analysis. Contemporary power systems are associated with serious issues of faults on high voltage transmission lines. Fault detection and localization is a focal point in the research of power systems area since the establishment of electricity transmission and distribution systems. OF THESIS POWER SYSTEM FAULT DETECTION AND CLASSIFICATION BY WAVELET TRANSFORMS AND ADAPTIVE RESONANCE THEORY NEURAL NETWORKS This thesis aims at detecting and classifying the power system transmission line faults. Answer: Generally four types of faults exist and are classified into two categories. Protective relay utilizes current and voltage signals to detect, classify, and locate the fault in transmission line. Li et al. In three-phase systems, a fault may involve one or more phases and ground, or may occur only between phases. Chanda et al. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Instant isolation of fault is necessary to maintain the system stability. Attitude of fault as basis; 3. Applying pattern recognition to fault classification for power system protection. Multiple Fault is a central component of more Abnormal Event Management in electric power systems. One Kalman filter assumes the features of the faulted phase while the other has features of an un-faulted phase. Faults may range in length from a few millimeters to thousands of kilometers. E. Trough Fault: This paper presents a method for fault classification in the power systems using a combination of support vector machine (SVM) classifier and Wavelet Transformation. The stability of an interconnected power system means is the ability of the power system is to return or regain to normal or stable operating condition after having been subjected to some form of disturbance.
