General description Nesta materia descríbense e analizan Sistemas de Enerxía Eléctrica (SEE).

A materia divídese en dous partes. A primeira está dedicada á análise de circuítos eléctricos e aos fundamentos das máquinas eléctricas; nesta parte cabe destacar a descrición, modelización e análise dos transformadores e as máquinas síncronas. Nunha segunda parte introdúcense os SEE, descríbense os elementos que os compoñen, así como aspectos operativos, construtivos e analíticos destes sistemas.

Calquera cambio ou evento relacionado coa docencia e avaliación da materia será anunciado polo profesor da mesma nas clases presenciais. Con todo, o profesor habilitará canles telemáticas alternativas para os alumnos que non asisten ás clases presenciais co obxecto de manterse ao corrente de calquera anuncio ou incidencia.

Methodologies
Methodologies Description
Guest lecture / keynote speech Introductory session to the subject.
Explanation of content by the teacher.
Problem solving Students solve calculation problems proposed by the teacher.
ICT practicals Subject to availability / Not confirmed:
-----------------------------------------------------
Practical sessions where students are responsible for carrying out exercises using ICT tools.

If it is not possible to allocate these hours to practicals, they will be reused in the lecture and problem-solving session.
Supervised projects This is an activity that the teacher may propose individually or in groups. The work can be of different natures, depending on the needs and circumstances of each course and always with the criterion of continuous assessment. Commonly, this will include, first, the study of a topic and/or the development of a software tool for a specific topic and, then, the resolution of problems related to the proposed topic.
Field trip Subject to availability / Not confirmed:
-----------------------------------------------------
Scientific and/or informative events or field trips.
Invited lectures or classes given by experts or by collaborating companies related to the competences of each subject.
Visits to industrial facilities related to the competences of each subject.

If it is not possible to allocate these hours to practical work, they will be reused for lectures and problem solving.
Objective test Answer to questions or solve exercises without means of consultation or with restricted means of consultation, in a specific limited space of time.

Supervised projects A1 A6 B2 B5 B13 B16 B7 B6 C1 C3 C5 C8 C9 C11 A 30% assessment of this section will be included in the case of supervised work, if this is the case. This will be voluntary. If this were not the case, this percentage would be added to the objective test. 30
Objective test A1 A6 B2 B6 C5 C1 In the correction of objective tests, the following factors may be taken into account, among other things:
- The follow-up of the instructions for its realization.
- The technical correctness of the calculations and results.
- The order, cleanliness and organization of the delivered material.
- The correct expression of the ideas and reasoning used. 		70
 
Assessment comments

The evaluation of the subject will be carried out through the following tests:

Activities that can be carried out during the school period:

  • It may be proposed to carry out supervised work with a value of up to 30% of the total value of the subject grade (in the case of the proposed carrying out of these scores it will not be recoverable).

Final objective test:

  • Completion of this objective test will be mandatory in order to pass the subject, 40% of the test must be presented and passed correctly in order to add up the score for the activities that can be carried out during the academic period. Depending on the organization or not of the activities during the academic period, the evaluation of the punctuation of the same would be added to the final percentage of the final objective test, which could vary between 70% and 100% of the weighting of the final grade, being necessary to exceed 50% of the test to pass the subject. The assessment method will be similar for the first and second opportunities.

Note on the assessment of non-face-to-face activities:

Non-face-to-face activities:

  • The teacher will reserve the right to request additional information by video conference in order to validate the veracity of the authorship of the content presented, reserving the right to a reduction of up to 100% of the score obtained in the case of inconclusive answers that may present doubts about the work done .

Additional conditions:

Condition of not presented:

  • Students who do not present themselves for the first or second opportunity objective test will obtain the status of not presented, regardless of the evaluation of the possible activities carried out during the academic period.

Early call:

  • Students who make an early call may retain the score obtained in the activities carried out during the academic period during a call. After this, if the subject has not been passed or no test has been taken, they will be evaluated through a final objective test, scoring it at 100% of the subject's grade, and it is necessary to pass 50% of the test to pass the subject.

Academic exemption:

  • Students with an academic dispensation will be exempt from class attendance and laboratory practices. The evaluation methods will be equivalent to those used with students enrolled in the face-to-face mode.

Fraudulent performance:

  • Students who fraudulently carry out any type of assessment activity (whether carrying out activities during the academic period or in the objective test), once verified, will automatically be classified as failed (numerical grade 0) in the corresponding call for the academic year, and may not evaluate the subject until the next call for the next academic year.

Other comments

To help achieve an immediate sustainable environment and fulfill the objective of action number 5: "Teaching and research that is healthy and environmentally and socially sustainable" of the "Green Campus Ferrol Action Plan":

The delivery of the documentary work carried out in this matter:

  • 1.1. It will be requested in virtual format and/or computer support.
  • 1.2. It will be done through Moodle, in digital format without the need to print them.
  • 1.3. If done on paper:

- Plastics will not be used

- Double-sided printing will be carried out.

- Recycled paper will be used.

- The printing of drafts will be avoided.

In addition to this, the full integration of students who, for physical, sensory, psychological or socio-cultural reasons, experience difficulties in having a suitable, equal and profitable access to university life will be facilitated.
