A Neuro-fuzzy Approach for the Fault Location Estimation of Unsynchronized Two-terminal Transmission Lines
Overhead transmission line is an element of electrical power systems that are most frequently experienced short circuit faults compared to other power system elements. Short circuit faults on overhead transmission line cause a relatively large current and therefore can damage mechanically the electrical equipment connected to the system. The protection system is essentially needed in this situa...
متن کاملUsing the Energy Balance Method in Estimation of Overhead Transmission Line Aeolian Vibrations
Original scientific paper This paper considers using the Energy Balance Method for estimation of overhead transmission line Aeolian vibrations. Since the damper’s efficiency strongly depends on its position, the procedure of determining the optimum position of the damper is described. It is observed that the optimal damper position depends on the span length also and that the best results can b...
متن کاملSingle-phased Fault Location on Transmission Lines Using Unsynchronized Voltages
The increased accuracy into the fault’s detection and location makes it easier for maintenance, this being the reason to develop new possibilities for a precise estimation of the fault location. In the field literature, many methods for fault location using voltages and currents measurements at one or both terminals of power grids’ lines are presented. The double-end synchronized data algorithm...
متن کاملTransmission line fault distance and direction estimation using artificial neural network
An accurate fault distance and direction estimation based on application of artificial neural networks for protection of doubly fed transmission lines is presented in this paper. The proposed method uses the voltage and current available at only the local end of line. This method is adaptive to the variation of fault location, fault inception angle and fault resistance. The Simulation results s...
متن کاملEstimation of Transmission Line Parameters using Fault Records
In this paper an innovative algorithm for the transmission line parameter estimation is presented. The important factors, such as synchronisation, processing of non-stationary signals and phasor estimation that are affecting the estimation accuracy have been addressed in the paper, and the set of pre-processing tools have been proposed. The new algorithm is tested using practical fault records....
