An alternative and simplified procedure is described to estimate the longitudinal resistances of transmission lines based on the real-time load profile. This method proposes to estimate the resistance parameters from the synchronized measurements of complex currents and complex voltages at the sending and receiving ends of transmission systems. The synchronized measurements can be in practice o...

In the context of energy industry decentralization, electrical networks encounter deviations power quality indices (PQI), including violations sinusoidality current and voltage signals, which increase errors in joint digital processing spatially separated signals devices. This paper addresses specific features using concept spatial coherence measurement signals. Methods for assessing during syn...

Phasor Measurement Unit’s (PMU) are power system devices which provide real time synchronized phasor measurements. Synchronization is achieved by same-time sampling of voltage and current waveforms by means of timing signals from the Global Positioning System Satellite (GPS). Synchronized phasor measurements make higher the standards of power system monitoring, control, and protection. Since PM...

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...
