What is it about?
In this paper, educational software for the reliability assessment of high/medium-voltage (HV/MV) substations and distribution feeders is presented. It is a useful tool for learning the utility of reliability indices of the HV/MV substations and their distribution feeders, and their influence on the electrical power system operation. By means of an interactive graphical interface, multiple configurations of HV/MV substation layouts can be selected. The Monte Carlo method and the equipment outages have been used to calculate the expected reliability performance of substations and primary distribution feeders. The proposed educational tool has been evaluated to measure students’ satisfaction, and questionnaire and results of this evaluation are presented and discussed.

Why is it important?
The use of this tool not only redresses the shortcomings of the traditional lecture methodology in performing a description of substations and their reliability assessment, but also improves the application of learning theory for the interpretation of results.
Perspectives
It is important to note that the proposed tool can help to design the distribution system with the best global reliability index, and to locate weak points that must be reinforced to get acceptable individual reliability indices. Hence, to learn how the remedial actions are related to the reliability indices, and how they can be modified to get acceptable reliability indices regarding to regulation.
