Figure 6. (Above) Simplified overview of the process. After the event the data from the SCADA system was analyzed. Figure 7. (Right) Analysis of the SCADA data for the process shows a distinct change in characteristics two days prior to the event. Had some form of automated pattern matching been in operation, a warning would have been issued at this time, and there is a high possibility that the resulting event would have been averted. resulting event, it would be possible to identify future circum- stances that match the pattern and thus indicate another potential occurrence of the same event. Summary An approach to the proactive management of networks has been considered. This approach integrates the existing utility systems such as SCADA and Work Management with information from other sources such as metrological data, and uses pattern-matching techniques to look for syndromes or potential events occurring in the network that require remedial work and automatically schedule field engineers to perform the work required before an incident occurs. With sufficient self-learning, the integrated system should improve its ability to identify potential problems, and water com- panies will be able to schedule remedial work in a timely manner, thus greatly reducing the number of unplanned incidents. we Steve Mustard is the president and CEO of au2mation, and can be reached at steve.mustard@au2mation.com.
