Distance relays are protective devices which main goal is the protection of transmission lines. However, the presence of harmonics and the exponentially decaying DC offset in the system voltage and current signals negatively affects the relay performance. In this paper, an adaptive phasor estimation method based on Artificial Neural Networks is presented to reduce these components’ effects, focusing...
This work proposes a software tool for fault diagnosis in power systems. The solution was developed to process the monitoring real-time data in Supervisory Control and Data Acquisition (SCADA) of the transmission and generation network of a Brazilian electric utility in order to assist operators of control centers with useful information about disturbances and the best procedures to reestablish the...
