Alarm processing and fault diagnosis using knowledge based systems for transmission and distribution network control

The authors present two expert system developments which are each concerned with utilizing, to the best effect, the increasing volume of SCADA (supervisory control and data acquisition) system data available to power system control staff. The systems presented, APEX and RESPONDD, are aimed at the two related fields of alarm processing and fault diagnosis, respectively. The areas of commonality between these systems are discussed, as well as details specific to each separate system, including a case of study illustrating the practical operation of each.<
