[0002] With the rapid progress of computer technology and the rapid development of power grid scale, the popularization of intelligent substation integrated automation system and the full implementation of unattended substations, the demand for information monitored by the power integrated monitoring system is increasing day by day. However, the corresponding power grid emergencies The types and characteristics are becoming more and more diverse, and the probability of occurrence is gradually increasing, resulting in an increasing workload of power grid monitoring. The time of power grid monitoring and inspection is too long, burying hidden dangers of accidents

The existing dispatching accident handling methods based on manual analysis, judgment, and decision-making can no longer meet the development needs of the future power grid, and the traditional alarm mode still has the following shortcomings:

[0003] (1) Using a single dimension, such as the classification of switch displacement, protection signal, and telemetry limit violation, is obviously not enough to accurately and fully describe the specific alarm information;

[0004] (2) It only provides one-way functions such as suppression / enablement and isolated alarm information confirmation. The alarm method is relatively monotonous, lacks user experience, and too much information is fatal to the operator. In the alarm information, the operator cannot quickly grasp the key information;

[0005] (3) The operator can only be notified of the information by means of tiling and simple classification and filtering, which are obviously too much and not smart enough;
