A time-driven and event-driven approach for substation feeder incident analysis

Feeder incident information is quite useful for evaluating the quality of the electricity distribution system. The improving scheme can be taken based on this information as well. In this paper, an adequate way for gathering this information was developed and the related messages from SCADA historical event log were analyzed by a novel methodology. For correctly and rapidly analyzing the collected messages purpose, this paper developed a time-driven and event-driven approach in order to express the exact feeder incident affairs. The feeder fault information can be fetched precisely and efficiently according to the result of this paper. Furthermore, the outage duration of the fault feeder, excluding the load transferring condition, was computed as well. For the sake of cyber security purpose, this paper developed a low cost and secured file transfer mechanism for transferring the event log from the SCADA system to an intranet web server. Corresponding to the web-based application software based on the result of this paper was consequently developed and installed on the sever of information management department of Taiwan Power Company (Taipower) for all SCADA control centers, and the software is running successfully.
