Detection, identification, and correction of bad sensor measurements for fault location

We initially review the readily devised methodology for transmission-grid disturbance location employing measurements from strategically deployed sensors. Later, we introduce one viable procedure for bad measurement detection and identification in order to accurately localize power system faults, thereby to enhance the practicality of the developed method. Furthermore, subsequent elimination of the errors resulting from bad sensor measurements will yield significantly enhanced fault-location accuracy. Simulated data regarding a particular fault scenario are illustrated using the modified IEEE 30-bus test grid.
