Research and Application of Intelligent Alarm System for Substation Based on Multi-source Data

With the development of the substation, there is a continuous demand for enhancing information alarm system performance. When the system experiences anomalies, there is a large amount of alarm information, but it lacks practical analysis and judgment. Related personnel find it challenging to swiftly assess the operational status and pinpoint fault locations, directly affecting the handling of alerts. Based on this, the paper first proposes a tiered collaborative intelligent alarm strategy, which integrates site-specific information fusion and application and analyzes alarm functions. Secondly, alarm technology based on multi-source data is offered for the substation. The paper generates intelligent alarms and brief reports using a unified benchmark signal and expert reasoning logic. Simultaneously, a simple and efficient data interaction mechanism between dispatch and substation facilitates the direct transmission of alarm information and customized notifications. Finally, the characteristics of the proposed intelligent alarm system are summarized, providing significant reference value for power grid operations and equipment management.
