ATP-EMTP study of current differential protection with synchronization and fault location functions
نویسندگان
چکیده
-This paper considers fault location and analytical synchronization of two-end measurements functions as embedded into a current differential protective relay. As a result of that, incomplete two-end measurements, i.e. three-phase currents measured at both line ends, while three-phase voltage only from only one end are considered for processing. Fault location and synchronization formulae are derived with considering a distributed-parameter model of a transposed overhead power line. The performed ATP-EMTP based evaluation proved the validity of the presented algorithms and their high accuracy.

In this paper, a new method has been presented for differential protection of power transformers. In this approach, chaotic method has been used for distinguishing of inrush current from internal fault current of the transformer. The proposed algorithm has been designed based on analysis of harmonic components of the differential current of the transformer due to internal faults and inrus...

Conventional fault location methods using voltages and currents of one terminal are not applicable to multiterminal transmission lines. So far some techniques have been presented to solve fault location problem for multi-terminal transmission lines. In these methods, lumped or distributed frequency domain models of transmission lines have been used. In multi terminal lines, faulty section shoul...

In this paper, performance evaluation of different schemes for location of fault in series compensated transmission lines are presented. A fault location algorithm using two end measurements and another fault location algorithm using one end measurements for transmission lines with series compensator at midpoint are simulated and results are obtained. Both the schemes are compared on the basis ...

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...
