CE19: Ability to apply electrical engineering.
The subject of Electrical Engineering aims to train students in the Degree in Engineering in Industrial and Automatic Electronics so that they are able to understand, interpret and perform calculations in electrical circuits linked to the electrical network (electrical engineering) and machines. electrical. Only the permanent regime will be considered, the transitional regime will not be the object of study. The subject is very strongly supported by the contents developed in the first year subject Electrical Systems. On the other hand, the contents studied here support subjects such as Power Electronics, Automation, and Robotics.
The course consists of 4 hours a week of face-to-face classes in the classroom and 2 hours a week of laboratory practices. Classroom work will be based on classes where the teacher will explain the theoretical concepts, problem solving and, occasionally, the collaborative resolution of exercises by students. He will also introduce the practices, which will be developed in small groups in the laboratory.
The internship sessions will be compulsory and will be carried out in groups of 15-20 students, divided into work teams of 2-3 students who will perform the work indicated in the corresponding internship script, in the laboratory of Electrical Machines and / or o Control.
Students will have the necessary documentation to follow the course.
The realization of a work of thematic affine to the asignatura is programmed outside the classroom.
Students will also have to devote additional time, non-contact, to the resolution of exercises, preparation of reports of laboratory practices and preparation of written tests.

With the aim of gathering evidence of the achievement of the learning outcomes essential to pass the subject, the following evaluative activities will be carried out:
Assessment activity 1: Partial written test 1 (Ex1). |
|
Description |
Written test (exam) of evaluation of the contents developed in the subjects 1 to 4. Solving problems of Electrical Engineering. |
Support material |
Notes and collection of problems. Bibliography. |
Deliverable and links to the evaluation. |
Test resolution. |
Links to learning outcomes |
Evidence of the achievement of the learning outcomes 1- (part relative to the electrical network) and 2-. |
Assessment activity 2: Partial written test 2 (Ex2). |

Support material |
Practice scripts. Laboratory material and instrumentation (hardware and software). Virtual Campus. |
Deliverable and links to the evaluation |
Eventually, prior report of each practical session. Subsequent report of each practical session. |
Links to learning outcomes |
Evidence of the achievement of learning outcomes 1-, 2- and 3-. |
Assessment activity 4: Work (T) |
|
Description |
This activity, which consists of carrying out a work, is carried out individually or eventually in groups. In this activity will study and simulate with computer some of the machines or circuits that are object of study in the asignatura, subject proposed by the professor. It will be necessary to prepare a report and make a presentation of the work. |
Support material |
Statement of the activity. Notes of the subject. Bibliography. PSIM simulation program. PSIM software manual. |
Deliverable and links to the evaluation |
Report, simulation files and presentation of the work. |
Links to learning outcomes |
Since the topic of each work will be customized for each student or group, there will be evidence of the achievement of 1- and 2- or 3- learning outcomes. Evidence that the student can convey information, ideas, problems and solutions to both specialized and non-specialized audiences (CB. 4). |
Rules for carrying out the activities
All the information about the activities to be carried out will be published on the virtual campus.
For each activity, information will be provided on the regulations to be followed and the particular conditions that govern them, sufficiently in advance.
In the written tests the teacher will provide a form. The student will only need writing utensils and a calculator.
Each of the laboratory practices will need a report (made by the group), which will be delivered to the teacher, in general, at the end of the practice session. The report will be evaluated and within approximately one week. Eventually, a preliminary report must be submitted at the beginning of the internship.
The work will be announced and organized at the beginning of the course.
Deliveries will not be accepted outside the established deadlines or through unforeseen means, except in cases of force majeure.
The ordinary final grade (QFO) of the subject is calculated as follows:
QFO = Ex1 0,35 + Ex2 0,35 + P 0,2 + T 0,1
Minimum grades:
Ex1 and Ex2: 3,0
P: 5,0
T: 4,0
In the event that any of the grades in the Ex1 and Ex2 activities are below the corresponding minimum mark, the ordinary final grade (QFO) of the subject will be limited to 5,0.
In case any of the grades for the P and T activities are below the corresponding minimum mark, the ordinary final grade (QFO) of the subject will be limited to 5,0.
All activities are compulsory. In the event that any of the activities are not carried out, the ordinary final grade (QFO) of the subject will be NP.
In case of not passing the subject in the ordinary assessment, there will be an extraordinary recovery session for Ex1 and Ex2 activities, in the form of an examination (ExR) of all the contents of the subject. The grade of this recovery (ExR) will replace that of Ex1 and Ex2 activities within the subject assessment, as indicated in the formula below, provided it is higher. P and T activities are not recoverable.
The extraordinary final grade (QFE) of the subject is calculated as follows:
QFE = ExR 0,7 + P 0,2 + T 0,1
In the event that the ExR exam grade is below 3,0, the final extraordinary grade (QFE) for the subject will be limited to 5,0.
In the event that any of the grades for the P and T activities are below the corresponding minimum grade, the extraordinary final grade (QFE) of the subject will be limited to 5,0.
