Teaching method
The different concepts are explained by the lecturer using adequated multimedia material and using real power systems examples as much as possible
The students will solve problems shared in the course materials in a semiautonomous way. oral communication are incentivized.
The students have contact with a finite element analysis software tool.
Evaluation method
The evaluation in this course follows one of two options:
Option A - 3 Minitests (MT1, MT2 and MT3) + 3 lab works (TL1, TL2 and TL3)
Theoretical Component (CT) = (0,1667*MT1 + 0,50*MT2 + 0,3333*MT3) >= 9,5 val.
MT3 grade >= 7 val.
Laboratorial Component (CL) = (0,375*TL1 + 0,3125*TL2 + 0,3125*TL3) >= 9,5 val.
Final Grade = 0,60*CT + 0,40*CL >= 9,5 val.
Option B - 1 Final Exam (EF) + 3 lab works (TL1, TL2 and TL3)
Theoretical Component (CT) = l*EF >= 9,5 val.
Laboratorial Component (CL) = (0,375*TL1 + 0,3125*TL2 + 0,3125*TL3) >= 9,5 val.
Final Grade = 0,60*CT + 0,40*CL >= 9,5 val.
In both options, studens will be approved in the course only if their final grade and also the grades in each one of the two components (CT and CL) is equal or higher than 9,5 values (scale from 0 to 20).
The grade of the laboratorial component (CL) may be subjected to oral discussion with the lecturer.
