Aims

The contents of the course are structured according to your goals, where you want the students to understand the problems associated with power networks, understand and establish the equations of Load Flo, and analyze the phenomena of short circuits in networks. The students implement the developed models in an computational environment.

Method of Evaluation
The student have two options:
Option 1: (TE + LAB)
Two tests during the semester (average 10 values). Laboraty work (average 10 values).
Option 2: (EX + LAB).
The final written exam at the final of the semester (minimum of 10 values). Laboraty work (average 10 values).
Final grade
The final grade (NF) is given by:
1st option: NF = 0.70 TE + 0.30. LAB
2nd option: NF = 0.70 EX + 0.30 LAB
