Final Thoughts

After discussing different aspects of disturbance analysis we can think of some ideas that can help us to faster improve the efficiency of the process.

The first thing that we need to do is to try to minimize or eliminate the involvement of protection engineers in some of the tasks that can be automated. First of all, it is clear that we need to develop as quickly as possible the common XML based format for the setting files.

This will remove the need for extracting information from proprietary setting files and replace it with automated processing of the available settings data and converting it into information that can be useful in the fault or disturbance analysis. It will help with the development of modules that can determine the expected behavior based on the settings in devices protecting a faulted segment of the electric power system.

Joining forces with the experts from the IEC TC57 working group 10 in standardizing the functional hierarchy modeling of multifunctional protection and control IEDs will further simplify the development of intelligent applications that can combine the knowledge of the configuration of the IED with its reported operation during the event under consideration. This will require the protection automation and control community to put pressure on the suppliers to speed-up the development of the capability from the IED interface tools to export event reports in the IEEE C37.239 COMFEDE format.

Once we have this ability to process settings and event reports information, we can use the definitions of the expected behavior of protection and control devices to develop hierarchical object-oriented fault analysis tools.

We should start with the simple stuff - first look at the distribution level which will give us the opportunity to achieve automated analysis of the biggest number of faults cleared by relatively simple protection schemes.
