Abstract
Power systems are transitioning into a new era by focusing more on the system characteristics like transient signals. Due to the demand of a more effective way to extract the fault line transient signals, many new methods are introduced into power system to solve the signal analysis problem in order to catch the main characteristics of status changes. Hilbert transform method as the foundation of solving such issues is widely used nowadays. As a result, it is essential to come up with a transfer method that can help analyze even the small changes of the system and can tell the physical significance of such changes. This project is a continuation of a previous work based on a research of transient signal analysis for proposing a method to extract signal changes that can be used in fault line detection and find the fault location. It will focus on the main characteristics of Hilbert transform method and then come up with a new method, the generalized sinusoidal transfer method that can help describe the signals' small changes. The simulations are done using Matlab and Simulink toolbox, and the models of fault line system are from several published research papers. To analyze power system fault signals using the generalized sinusoidal method can help improve the accuracy and efficiency of system analysis. And the new proposed method is of great value to extract transient power system signal and find the fault line and fault location.
