Analysis and design SCADA alarm management system strategy based on jitter characteristics

The alarm management system often has the problem of "flood" alarm for a period of time. A large number of flooding alarm will cause a crisis of trust between human and machine and reduce the availability of the system. The article first investigates the problem of unbalanced alarm distribution in the actual application of the alarm system. In order to adjust the probability density of different alarms, it is necessary to introduce the concept of alarm chatter rate that characterizes the arrival density of alarms. Then, the description principles and methods of the characteristics of alarm redundancy chatter are given. An alarm chatter rate characterization algorithm combining attenuation factor and natural alarm arrival rate is proposed. Finally, the concrete realization of the compression strategy based on this feature processing is given. Comparing and analyzing in actual test, this method can effectively reduce the number of redundant alarms and improve the efficiency of human-machine information interaction expression.
